In this study a total of 29 Eremias strauchi strauchi specimens (10 males, 16 females and three juveniles), collected from different localities in northwest of Iran were examined. The study was based on morphological features including color pattern, morphometric measurements, pholidotic characters, as well as ecological and biological observations especially habitat, reproductive biology and distribution. Habitat features and new distribution localities were documented. Egg characters of Eremias strauchi strauchi such as shape, size, number and color are reported for the first time. Also, some other new information on this species has been given.

The Northwest of Iran, covering the three provinces of Ardabil, East Azerbaijan and West Azerbaijan, is a special area that, due to its particular geographical and climatic conditions has a rich biodiversity. The present study was conducted with the aim of studying the habitat, substrate type, feeding, conservation and distribution of lizards in this area from 2003 to now. Our results have revealed that there are 20 lizard species belonging to 13 genera and 5 families in this area. Lacertid lizards have the highest species diversity with 12 species. We also found that high ranges of habitats with a different substrate types are inhabited by lizard species. The number of species in pine regions compared with other types of area is considerably greater. The conservation status of lizards is unknown and requires further study.

Northwestern Iran has unique geographical and climatic conditions that support a rich flora and fauna. In
view of the lack of in-depth studies on the lizards of the region, an investigation was started in the northern part of
Ardabil Province for an inventory of this component of the fauna and their habitats. Collections were made from
October 2003 to June 2005 and 165 specimens were collected and identified. Five families, 12 genera and 15 species
are represented, including Agamidae: Laudakia caucasia, Phrynocephalus persicus, Trapelus ruderatus; Lacertidae:
Lacerta media media, Lacerta strigata, Lacerta brandtii, Darevskia raddei raddei, Eremias strauchi strauchi,
Eremias arguta, Ophisops elegans; Scincidae: Mabuya aurata transcaucasica, Eumeces schneiderii princeps,
Abelepharus bivittatus; Anguidae: Pseudopus apodus and Gekkonidae: Cyrtopodion caspium caspium. Comparing
this list to the data provided by Anderson (1999), it seems that most of the lizards are being reported for the Province
for the first time. The families Gekkonidae and Anguidae are newly recorded, and the gecko Cyrtopodion caspium is
first recorded from the west and northwest of Iran. With seven species represented in the area, lacertids have the highest
species diversity among the lizard families and need further study. Habitat features also have been given for all

The Iranian Plateau is an area of highly complex landscape and incredibly diverse habitats, from salt deserts to temperate forests. Such a heterogeneous environment, at the crossroads of Asia, Europe, and Africa, fuels the high diversity and uniqueness of the Iranian fauna and flora. Nevertheless, our understanding of the historical processes that shaped the Iranian biodiversity remains limited. In this context, we revisit the evolutionary history of the two most widespread lizard species on the Iranian Plateau (Eremias persica and Mesalina watsonana) to explore whether these two taxa of similar ecology have been subjected to similar historical processes. To achieve that, we performed a series of phylogenetic analyses and thoroughly tested all possible alternative topologies based on available mitochondrial sequences (cytochrome b and 12S ribosomal RNA). Additionally, we estimated the number of mitochondrial clusters based on a novel single-locus delimitation method and the time of their divergence, using recently inferred evolutionary rates for lacertid species. The results indicate that the two taxa have been shaped by similar physiographic and climatic barriers since both phytogenies split into similar geographical clusters. However, E. persica has twice as long evolutionary time on the Iranian Plateau than M. watsonana. The first divergence of E. persica was estimated in the Middle Miocene (~13 Mya), at the time of the major uplift of the Zagros mountain range. The Upper Miocene tectonic rearrangement that resulted in the uplift of the Alborz mountains coincides with the original split in M. watsonana (~6.6 Mya) and several contemporaneous splits within E. persica.

We studied, for the first time, the age structure of Eremias strauchi strauchi (Kessler, 1878) from a sample (18 adults) of a population living in the vicinity of Iğdır (eastern Turkey) using the skeletochronological method. The maximum observed longevity was 7 years for males and 5 years for females. The age of males ranged from 4 to 7 years (mean 4.91, n = 12), while that of females ranged from 4 to 5 years (mean 4.66, n = 6). The average snout–vent length (SVL) was 61.10 mm in males and 60.82 mm in females. The differences in mean age and SVL between sexes were not statistically significant. Intersexual differences in body size were male-biased, but this state was not statistically significant. Age and SVL were positively correlated in both sexes.

Morphometric evaluation of limb proportions in five sympatric desert lacertas of the genus Eremias, namely E. velox, E. grammica, E. intermedia, E. lineolata, and E. scripta inhabiting southern Balkhash Lake region (Sary-Ishyk-Otrau desert), Kazakhstan, was made. Considerable species differences in proportions of some limb segments associated with locomotion adaptations (burrowing, climbing etc) of these lizards have been found as well as sexual dimorphism and age variability. Associations among morphometric peculiarities (limb proportions), locomotion activity, spatial, temporal, and trophic characteristics of ecological niches of sympatric species are discussed.

Twenty-four species of lacertid lizards were examined at 31 sites in western Yogoslavia, Greece and Iberia. Comparative observations were made on over 4500 individual lizards, noting such features as times of activitiy, hunting methods, diet, micro- and macrohabitat, refuges used and body temperature. These data are used as a basis for assessing resource partition in related sympatric species, for find out whether different systematic groups have characteristic types of niche, and for comparing cumminity structures in the peninsulas of southern Europa.

Arnold, E.N. (2002) -
Differences in surface structure (ober- hautchen) of body scales of lacertid lizards involve cell size, shape and surface profile, presence or absence of fine pitting, form of cell margins, and the occurrence of longitudinal ridges and pustular projections. Phylogenetic information indicates that the primitive pattern involved narrow strap-shaped cells, with low posteriorly overlapping edges and relatively smooth surfaces. Deviations from this condition produce a more sculptured surface and have developed many times, although subsequent overt reversals are uncommon. Like variations in scale shape, different patterns of dorsal body microornamentation appear to confer different and conflicting performance advantages. The primitive pattern may reduce friction during locomotion and also enhances dirt shedding, especially in ground-dwelling forms from moist habitats. However, this smooth microornamentation generates shine that may compromise cryptic coloration, especially when scales are large. Many derived features show correlation with such large scales and appear to suppress shine. They occur most frequently in forms from dry habitats or forms that climb in vegetation away from the ground, situations where dirt adhesion is less of a problem. Microornamentation differences involving other parts of the body and other squamate groups tend to corroborate this functional interpretation. Microornamentation features can develop on lineages in different orders and appear to act additively in reducing shine. In some cases different combinations may be optimal solutions in particular environments, but lineage effects, such as limited reversibility and different developmental proclivities, may also be important in their genesis. The fine pits often found on cell surfaces are unconnected with shine reduction, as they are smaller than the wavelengths of most visible light.

In this paper we deal on the ultraviolet color (invisible to us): where we can find it, the capability of animals to see it and the advantages that this color perception offers to them. As the simplest way to detect it is the photography, we describe and review how to photograph the UV, as a result of 15 years of amateur experience, searching
and testing nearly in complete blindness due to the lack of practical information about “how to do it”. We describe the different kinds of photography (chemical and digital); the cameras and objectives suitable (both astronomically expensive ones and cheap options); what are the best characteristics that the objectives should have for this purpose; the films suitable for their use in chemical photography; the different filters (current or discontinued) manufactured along the years; and the subtle combinations among the different materials to obtain pure UV photographs. This
kind of scientific photography is mainly used in forensics, forgery detection, art dermatology and less in Natural History, despite the fact that a great part of animals see this color and use it in important questions of their biology as the social behavior, mate choice or the food search.

Animals communicate via a variety of sensory channels and signals. Studies on acoustic and visual communication systems suggest that differences in the physical environment contribute to the variety of signalling behaviour, with species investing in those signals that are transmitted best under the local conditions. Whether or not environmental tuning also occurs in chemical communication systems has received much less attention. In the present study, we examined the effect of several aspects of the physical environment on the chemical communication system of lacertid lizards (family Lacertidae). The numbers of femoral pores are used as a proxy reflecting how much a particular species invests in and relies upon chemical signalling. Femoral pores are specialized epidermal structures that function as a secretion channel for the waxy substance produced by glands. In some lacertid species, the secretion carries infochemicals that play an important role in social communication. The number of femoral pores varies considerably among species. We have compiled data on femoral pore numbers for 162 species and tested for the effects of climate and substrate use. After correcting for body size and taking the phylogenetic relationships among the species into account, we found no effect of climate conditions or latitude on species pore numbers. Substrate use did affect pore numbers: shrub-climbing species tended to have fewer femoral pores than species inhabiting other substrates.

A new species of Eremias has been described from the Cholistan Desert of Pakistan. It constitutes the first record of the genus Eremias from the Oriental (Indian) region. The species has been named Eremias cholistanica, after the Cholistan Desert of Pakistan. This striped desert lacerta is not only different from all its congeners in several morphological characteristics but has been collected from an area distant from the previous known range of Eremias.

Present studies are aimed to document the herpetofauna of Cholistan Desert and study its ecology. During the last three years from 2001 to 2003, attempts have been made to collect and observe the amphibians and reptiles in different parts of Cholistan Desert. More than four thousand specimens belonging to 44 species have so far been collected/observed from the study area. Among different collecting techniques adopted for these studies, “Pit-fall” traps and “Hand Picking” showed best results. The voucher specimens have been catalogued and are presently lying with Pakistan Museum of Natural History, Islamabad.

A complete catalogue is provided for the type specimens of lacertid lizards in the herpetological collection of the Zoological Museum, Berlin, as of December, 1993. The collection contains a total of 514 type specimens, representing 63 taxa, of which 42 are currently regarded as valid at the specific or subspecific level. Types representing an additional four taxa appear to have been lost from the collection. The collections are especially rich in African lacertid types and in historically significant specimens collected early in the Nineteenth Century by Pallas, Eversmann, and Hemprich & Ehrenberg. Also present are the type series of many subspecies of Podarcis lilfordi and P. pityusensis described by Eisentraut.

Research of the herpethofauna of the Lower Volga area began by academic expeditions of the 18 century.
As a result of these researches, many new species of amphibians and reptiles were described. Some of
these species descriptions are recognized as the priority ones. The earliest data on amphibians and reptiles
in the territory of the current Volgograd region were collected at the beginning of the 19 century (Kondratyev,
1885). Important data on the Sarepta amphibians and reptiles were also published by A. Becker
(1855). Later, a new viper species was described on the basis of the Sarepta materials (Christoph, 1861).
At the beginning of the 20 century, materials on amphibians and reptiles were collected by V. Kiziritsky
in the territory of the Tsaritsyn (currently Volgograd) region (1913). The results of these works are reflected
in A. M. Nikolsky`s reports (1915, 1916, and 1918). A next stage of research began in the middle
of the 20 century by works of the Stalingrad zoologists (N. A. Kosareva, B. S. Kubantsev, T. I. Zhukova,
N. N. Kolyakin, etc.). Later, zoologists from Moscow and other Russian cities conducted their research
there as well. The results of all these studies on inventory of the herpethofauna of the Volgograd region
are summarized in Professor B.S. Kubantsev’s works (1996, 2003, etc.). Now, local zoologists continue
studying the amphibian and reptile fauna of the Volgograd region. A significant contribution to our
knowledge on distribution, number and ecology of reptiles was brought by Saratov researchers. But the
herpethofauna inside a considerable territory of the Lower Volga area is still poorly studied.
Key words: amphibians, reptiles, fauna, study, history, Volgograd region, Russia.

Изучение герпетофауны Нижнего Поволжья началось в академических экспедициях ХVIII в. В результате этих исследований было описано много новых видов амфибий и рептилий, часть из которых признана сейчас как валидными. Первые сведения о земноводных и пресмыкающихся на территории нынешней Волгоградской области были собраны в начале ХIХ в. (Кондратьев, 1885). Важные сведения о герпетофауне Сарепты опубликовал также A. Becker (1855). Позже по материалам из Сарепты был описан новый вид гадюки (Christoph, 1861). В начале ХХ в. на территории Волгоградской области герпетологические материалы собирал В. Кизирицкий (1913). Результаты этих работ содержатся в сводках А. М. Никольского (1915, 1916, 1918). Следующий этап исследований начался в середине ХХ в. работами сталинградских зоологов (Н. А. Косарева, Б. С. Кубанцев, Т. И. Жукова, Н. Н. Колякин и др.). Позже здесь проводили исследования также зоологи из Москвы и других городов России. Итоги всех этих работ по инвентаризации герпетофауны Волгоградской области подведены в ряде статей Б. С. Кубанцева (1996, 2003 и др.). Сейчас герпетофауну Волгоградской области продолжают изучать местные зоологи. Большой вклад в познание распространения, численности и экологии рептилий внесли также саратовские исследователи. Но герпетофауна значительной территории Нижнего Поволжья по-прежнему остается еще слабо изученной.

Animals must cope with and be able to move effectively on a variety of substrates. Substrates composed of granular media, such as sand and gravel, are extremely common in nature, and vary tremendously in particle size and shape. Despite many studies of the properties of granular media and comparisons of locomotion between granular and solid substrates, the effects of systematically manipulating these media on locomotion is poorly understood. We studied granular media ranging over four orders of magnitude in particle size, and differing in the amount of particle shape variation, to determine how these factors affected substrate physical properties and sprinting in the generalist lizard Eremias arguta. We found that media with intermediate particle sizes had high bulk densities, low angles of stability and low load-bearing capacities. Rock substrates with high shape variation had higher values for all three properties than glass bead substrates with low shape variation. We found that E. arguta had the highest maximum velocities and accelerations on intermediate size particles, and higher velocities on rock than glass beads. Lizards had higher stride frequencies and lower duty factors on intermediate particle size substrates, but their stride lengths did not change with substrate. Our findings suggest that sand and gravel may represent different locomotor challenges for animals. Sand substrates provide animals with an even surface for running, but particles shift underfoot. In contrast, gravel particles are heavy, so move far less underfoot, yet provide the animal with an uneven substrate.

Locomotor performance in lizards is strongly affected by structural habitat. Understanding this relationship allows us to predict species distributions across habitat types. However, little information is available about the ecological role of the locomotion of multiocellated racerunner (Eremias multiocellata) in the desert steppe ecosystem of Inner Mongolia, China. Herein, we studied the effects of habitat structure on the locomotor performance of this lizard species in the field. We found that the sprint speed of this lizard declined significantly with increasing vegetation coverage. Manipulative experiments were further conducted to examine the effects of branch barriers and surface substrates on the sprint speed of the lizard. We found that the sprint speed was significantly influenced by the surface substrates and branch barriers, and there were no interactions between them. Branch barriers impeded sprint speed, and E. multiocellata showed better locomotor performance on sandy rather than loamy substrates. Our results indicate that E. multiocellata tends to occupy open areas with sandy substrates, but its locomotor performance is not closely associated with habitat preference.

The current book provides a synthesis of the information concern-
ing field identification of all the species and subspecies of Amphibia
and Reptilia hitherto registered in Bulgaria. It comprises 61 species
and 23 subspecies, among which 5 species (Pelophylax lessonae, P.
kurtmuelleri, Hemidactylus turcicus, Eremias arguta, Montivipera
xanthina) that have not been found yet on the territory of the
country, but which are known from sites in proximity to Bulgar-
ian frontiers. The frogs and toads are represented with 14 spe-
cies, newts and salamanders with 6 species, turtles and tortoises
with 7 species (Trachemys scripta introduced; Caretta caretta and
Chelonia mydas considered extinct), and snakes with 19 species
(Vipera aspis and V. ursinii considered extinct). The structure of
each species’ description includes the following headings: Name,
Diagnosis, General Distribution, Distribution in Bulgaria, Habitats,
and Biology. Besides in Bulgarian and Latin, all species are sup-
plemented with their English, French, German and Russian names.
All synonyms in the main herpetological literature are listed after
the currently accepted Latin name. Original keys for identification
of the families, genera and species, based entirely on morphologi-
cal characters of adult specimens, as well as on the structure of
amphibians’ eggs and larvae, are elaborated to facilitate the users.
A photo gallery, comprising original colour photos shot in nature,
and numerous line drawings of different key characters are made
for better distinction between the species. For purely conservation-
al reasons, the distribution maps not only indicate the scientifically
confirmed species distribution in the country, but also show the
areas with suitable habitats where a given species is likely to oc-
cur. The degree of suitability is indicated with a different degree
of shading: optimal (black); suboptimal (80% gray); suitable (60%
gray); less suitable (20% gray); white means unsuitable. The guide
is also introducing the readers to some general aspects of the tax-
onomy, systematics, morphology, biology and ecology of herpeto-
fauna. Special chapters are devoted to the methods of observation
and capture of amphibians and reptiles, first aid after a snake’s
bite, and the relationship between herpetofauna – humans. The
status of each species according to main biodiversity conservation
acts and conventions is given in Table 1. Being the first publication
of its kind, the book is intended for professional herpetologists,
students or nature lovers.

Terrestrial route counts of reptiles in 24 localities of the plateau Ustyurt were carried out in 2007 – 2008.
474 individuals of 15 species were found along a total of 243.5 km passed. Based on the results of our
survey, the reptile population structure has been clarified in 12 landscapes. The low specific diversity and
population density of reptiles were observed everywhere. 2 to 8 species with a population density of 1.9 –
8.4 individuals per ha were found in certain landscapes. In terms of abundance, the reptiles belonged to
rare or common species. The steppe agama Trapelus sanguinolentus and the Central Asian tortoise
Agrionemys horsfieldii were the most abundant. Four racerunner species (Eremias) had a pronounced
confinement to various types of substrate, which allowed them to occupy the dominant position in the
landscapes by numbers. Four main landscape complexes of reptile communities were identified, which
changed zonally in the latitudinal direction. The attitude of the reptiles to their environmental conditions
is discussed. The plasticity of the Eremias species to substrates is estimated, and to distinguish its types is

Many regions of the former USSR still re- ceive little attention from Western visitors, herpetologists not excluded. For the Cau- casus Mountains this is all the more sur- prising since the area forms a zone where northern and Middle Eastern flora and fauna meet, and which is thus of considera- bly zoogeographical interest.
Presently we find three larger states in the Caucasus: Georgia, Azerbaijan and Arme- nia. Turkey borders to the southwest, Iran to the southeast, and in the north it is the Russian federation. Various smaller parts claim independence. The Black Sea forms the natural western boundary, the Caspian Sea the eastern one.
Herpetologically the Caucasus is historically well-known because of the work of Darev- sky and collaborators on the rock lizards (at the time still in the large genus Lacerta, now in Darevskia) and the discovery of the first case of parthenogenesis in vertebrates (DAREVSKY, 1967; DAREVSKII, 1978; DAREVSKY & KULIKOVA, 1961).
Below we will concentrate on the results of our field trip to Georgia during the last two weeks of June 2003. Predictably, because of our common interest in the group, the lacertids will receive the most attention.

A phylogenetic-comparative approach was used to assess and refine existing secondary structure models for a frequently studied region of the mitochondrial encoded large subunit (16S) rRNA in two large lizard lineages within the Scincomorpha, namely the Scincidae and the Lacertidae. Potential pairings and mutual information were analyzed to identify site interactions present within each lineage and provide consensus secondary structures. Many of the interactions proposed by previous models were supported, but several refinements were possible. The consensus structures allowed a detailed analysis of rRNA sequence evolution. Phylogenetic trees were inferred from Bayesian analyses of all sites, and the topologies used for maximum likelihood estimation of sequence evolution parameters. Assigning gamma-distributed relative rate categories to all interacting sites that were homologous between lineages revealed substantial differences between helices. In both lineages, sites within helix G2 were mostly conserved, while those within helix E18 evolved rapidly. Clear evidence of substantial site-specific rate variation (covarion-like evolution) was also detected, although this was not strongly associated with specific helices. This study, in conjunction with comparable findings on different, higher-level taxa, supports the ubiquitous nature of site-specific rate variation in this gene and justifies the incorporation of covarion models in phylogenetic inference.

We discuss three aspects of the thermal biology of lacertid lizards. First, we provide an overview
of the available data on field body temperatures (Tb), the thermal sensitivity of various performance
functions and selected body temperatures in different species of lacertid lizards. We also
briefly summarise information on the mechanisms of thermoregulation. Second, we discuss recent
developments to estimate the »precision« of thermoregulation, and the contribution of distinct behavioural
mechanisms. Finally, we revise available evidence for the existence of evolutionary adjustments
of thermal characteristics in lacertid lizards. Existing studies have mainly dealt with
within- and among-species differences in thermoregulatory behaviour (selected temperatures) and
thermal physiology of adults (optimal temperatures, heating rates). Available data provide only
limited evidence for clear-cut evolutionary shifts in thermal physiology characteristics along climatic

The disturbance of the thyroid system and elimination of chiral pyrethroid pesticides with respect to enantioselectivity in reptiles have so far received limited attention by research. In this study, bioaccumulation, thyroid gland lesions, thyroid hormone levels, and hypothalamus-pituitary-thyroid axis-related gene expression in male Eremias argus were investigated after three weeks oral administration of lambda-cyhalothrin (LCT) enantiomers. In the lizard liver, the concentration of LCT was negatively correlated with the metabolite-3-phenoxybenzoic acid (PBA) level during 21 days of exposure. (+)-LCT exposure induced a higher thyroid follicular epithelium height than (−)-LCT exposure. The thyroxine levels were increased in both treated groups while only (+)-LCT exposure induced a significant change in the triiodothyronine (T3) level. In addition, the expressions of hypothalamus-pituitary-thyroid axis-related genes including thyroid hormone receptors (trs), deiodinases (dios), uridinediphosphate glucuronosyltransferase (udp), and sulfotransferase (sult) were up-regulated after exposure to the two enantiomers. (+)-LCT treatment resulted in higher expression of trs and (−)-LCT exposure led to greater stimulation of dios in the liver, which indicated PBA-induced antagonism on thyroid hormone receptors and LCT-induced disruption of thyroxine (T4) deiodination. The results suggest the (−)-LCT exposure causes higher residual level in lizard liver while induces less disruption on lizard thyroid activity than (+)-LCT.

Dermal exposure is regarded as a potentially significant but understudied route for pesticides uptake in terrestrial reptiles. In this study, a native Chinese lizard was exposed to control, diflubenzuron or flufenoxuron contaminated soil (1.5 mg kg−1) for 35 days. Tissue distribution, liver lesions, thyroid hormone levels and transcription of most target genes were examined. The half-lives of diflubenzuron and flufenoxuron in the soil were 118.9 and 231.8 days, respectively. The accumulation of flufenoxuron in the liver, brain, kidney, heart, plasma and skin (1.4–35.4 mg kg−1) were higher than that of diflubenzuron (0–1.7 mg kg−1) at all time points. The skin permeability factor of flufenoxuron was more than 20-fold greater than that of diflubenzuron at the end of exposure. However, the liver was more vulnerable in the diflubenzuron exposure group. The alterations of triiodothyronine (T3) and thyroxine (T4) level after diflubenzuron or flufenoxuron exposure were accompanied with the changes in the transcription of target genes involved not only in hypothalamus-pituitary-thyroid (HPT) axis (sult, dio2, trα and udp) but also in metabolism system (cyp1a and ahr). These results indicated that flufenoxuron produced greater body burdens to lizards through dermal exposure, whereas both diflubenzuron and flufenoxuron have the potential to disturb metabolism and thyroid endocrine system.

Lambda-cyhalothrin (LCT) is a widely used pyrethroid with neurotoxicity. However, little is known about the toxicokinetics of LCT in reptiles. In this study, the absorption, distribution, metabolism and excretion of LCT in Chinese lizards (Eremias Argus) were determined following a single dose (10 mg kg−1) treatment. In the liver, brain, gonads and skin, LCT levels peaked within several hours and then decreased rapidly. However, the concentration of LCT gradually increased in the fat tissue. More than 90% of the LCT dose was excreted in the faeces. One LCT metabolite, 3-phenoxybenzoic acid (PBA), was detected in lizard plasma and tissues. PBA preferentially accumulates in the brain and plasma. The half-life of PBA in the brain was 3.2 days, which was 35.4-fold greater than that of LCT. In the plasma, the concentration of PBA was significantly higher than that of LCT. The bioaccumulation of LCT in tissues was enantioselective, and the enantiomeric fractions (EF) ranged from 0.72 to 0.26. The preferential accumulation of enantiomers changed according to exposure time, but the reasons behind this phenomenon were not clear. For pathological analysis, vacuolation of the cytoplasm and large areas of necrosis were observed in the liver sections after 168 h of dosing. The liver tissues exhibited both decreases in the hepatosomatic index and histopathological lesions during the exposure period. In this study, the effect concentration of LCT in lizards was 200-fold lower than its LD50 value used in risk assessments for birds. These results may provide additional information for the risk assessment of LCT for reptiles and indicate that birds may not be an ideal surrogate for reptile toxicity evaluation.

Flufenoxuron is a widely used pesticide to inhibit the synthesis of chitin during insect development and its effect on the growth of lizards has been little addressed. The hypothalamus-pituitary-thyroid (HPT) axis plays an important role on the development of lizards. In this study, the lizards at different development stages (proliferation and resting stages) were exposed to flufenoxuron for 21 days. The plasma thyroid hormone levels, thyroid gland histopathology and expression profiles of thyroid hormone receptors (trα, trβ), deiodinases (dio1, dio2), and transthyretin (ttr) genes were measured to evaluated the toxic effect of flufenoxuron on the HPT axis at different stages. The flufenoxuron exposure showed more seriously effect on the triiodothyronine (T3) level at resting phase than that at proliferation stage. The follicle epithelium cell height in the thyroid was only significantly increased when the exposed male lizards were at proliferation stage. The alteration of HPT axis-related genes expression was gender and tissue dependent after flufenoxuron treatment. The lizards exposed to flufenoxuron showed that the trα, trβ, dio1, dio2, and ttr genes in the female liver were more sensitive at the proliferation stage than that at the resting stage. In the male brain, the expressions of trα, trβ, dio1, and dio2 gene were significant decreased at proliferation stage while significant increased at resting stage after flufenoxuron exposure. Therefore, the thyroid endocrine system of lizards could be affected by the flufenoxuron exposure and the different development stage should also be considered when study the toxic effect of contaminants on the lizards.

More and more studies are focusing on toxic effect of pesticides on lizards. However, the responses of different life-stage lizards to pesticides have not been reported. In this study, according to RNA-seq library data, thyroxine 5′-deiodinase activity showed significant difference between mature and immature lizard liver. In addition, triiodothyronine (T3) level in immature lizard serum was higher than that in mature lizard serum. Thus, we investigated the thyroid disruption of flufenoxuron with different concentrations (0, 5, 20 mg/kg) to both mature lizards and their offspring. No significant differences were observed in immature lizard body weight compared between control and exposure groups while the body weight of mature lizards was significantly decreased after flufenoxuron exposure. Moreover, the levels of thyroid hormones and the expression of thyroid related genes changed with exposure concentration of flufenoxuron and exhibited different regulation mechanism between mature and immature lizards. In immature lizard liver, trα, trβ, dio1 and ugt genes controlled the thyroid hormone levels interfered by flufenoxuron. In contrast, the thyroxine (T4) pathway in mature lizard liver was significantly disrupted especially by 20 mg/kg flufenoxuron exposure. This study elucidated the different thyroid disruption effects of flufenoxuron to lizards based on different exposure doses and lizard life stages.

Benzoylurea pesticides (BPUs) are widely used to control the locust, but the toxicokinetics and hepatotoxicity of BPUs in lizards have not been investigated. In this study, the tissue distribution, metabolism and liver toxicity of diflubenzuron and flufenoxuron were assessed in the Eremias argus following a single oral exposure. Diflubenzuron preferred to accumulate in the fat and brain (>1.0 mg kg−1) and was rapidly eliminate in other tissues. In the liver, 4-chloroaniline was one of diflubenzuron metabolites, although with a concentration less than 0.05% of the accumulated diflubenzuron. No significant difference was observed in the liver histopathology between the control and diflubenzuron exposure group. The expressions of Cyp1a and Ahr gene which control the cell apoptosis were also equal to the control level. After flufenoxuron exposure, biomodal phenomenon was observed in the liver, skin, brain, gonad, kidney, heart and blood circulation was an important route for the flufenoxuron penetration. The concentrations of flufenoxuron in all tissues were greater than 1.0 mg kg−1 at 168 h. The excretion of flufenoxuron in the faeces was 1.5 fold higher than diflubenzuron. The hepatocytes in the flufenoxuron treated group showed vacuolation of cytoplasm and decreased nucleus. In addition, the Cyp1a and Ahr genes were significantly up-regulated in the flufenoxuron exposure group. These results suggested that the higher hepatotoxicity of flufenoxuron may be attributed to the higher residual level in the lizard tissues and the Cyp1a and Ahr genes can serve as biomarkers to assess the liver toxicity.

Diflubenzuron (DFB) is a potential endocrine-disrupting chemical. However, its thyroid endocrine effect on reptiles has not been reported. In this study, immature lizards (Eremias argus) were exposed to 20 mg kg−1 DFB once a week for 42 days through oral or dermal routes. Their body weight, plasma thyroid hormone levels, thyroid gland histology and the transcription of hypothalamic–pituitary–thyroid (HPT) axis-related genes in different tissues were assessed to explore the effects of DFB on the HPT axis of lizards. The body weight decreased significantly only after the dermal exposure to DFB. Triiodothyronine (T3) to thyroxine (T4) ratio in the male plasma also significantly increased after the dermal exposure. After oral exposure, the activity of thyroid gland was positively related to the thyroid hormone levels. Furthermore, the alterations in thyroid hormone levels affected the HPT axis-related gene expression, which was tissue dependent and sexually selected. The thyroid hormone receptor genes (trα and trβ) in the brain and thyroid were more sensitive to oral exposure. However, only the dermal treatment affected the trα, trβ and type 2 deiodinase (dio2) genes in the male liver. These results suggest that DFB exposure caused sex-specific changes in the thyroid function of lizards, and the dermal treatment may be an important route for the risk assessment of reptiles.

In this study, the different metabolic pathways of lambda-cyhalothrin (LCT) enantiomers in Eremias argus feces and enantioselective disruption on hypothalamus-pituitary-gonad (HPG) system were investigated. After 7 days oral exposure to LCT enantiomers, the concentration of 3-phenoxybenzoic acid (PBA), hydroxylated and sulfated LCT were higher in the (+)-LCT exposure group than that in the (−)-LCT exposure group, which indicated a higher metabolic rate of (+)-LCT than (−)-LCT. Although no significant differences were seen on lizard body weight after enantiomers’ exposure, the gonadosomatic index was dramatically decreased. The testicular impacts such as increased seminiferous tubule diameters were only observed in the (+)-LCT exposure group. Consistent with this result, the expression of ar gene in the (+)-LCT exposure was significantly higher than that in the (−)-LCT exposure group. In addition, the stronger binding affinity of AR with (+)-LCT further demonstrated the more serious disruption of (+)-LCT on lizard HPG axis than (−)-LCT. This study first elucidated the metabolic pathway and endocrine effects of LCT in lizards at enantiomeric level and provided some evidence for lizard population decline.

This study was conducted to find the sexual size dimorphism(SSD) in morphometric characters of three species , Eremias argus, Takydromus amurensis and T. wolteri in lacertid lizard from Korea. Six external traits, snout‐vent length, tail length, head length, head width, forelimb length and hind-limb length were focused to compare two sexes among the each three lizards. Student`s t‐test was used to compare the adult SVL between the sexes for each species. For the other parts of the body, a one‐way analysis of covariance(ANCOVA) with SVL as the covariate was used. In all these species, males have longer tail and head than females like general lacertid lizard. In addition, male E. arugus have broader head and longer forelimbs and hind-limbs than conspecific females. Likewise, male T. wolteri have broader head than females. In the three lacertid lizards from Korea, snout‐vent length did not significantly differ between the sexes. To understand the causes for SSD in SVL, ecological information, such as the presence/absence of male-male combat and the correlation between the SVL of female and litter size, is required. Therefore, further ecological study on the three species of lacertid lizard from Korea will make it possible to explain the reason SSD is not found in SVL.

Numerous studies suggested that reptiles are sensitive to environmental pollution and the abundance of many species are in decline. Our research is aim to assess the toxic effects of pesticide in reptiles. And we also want to supply some data about nondestructive samples for environmental risk assessment in reptiles. Lizards were orally administered a single-dose of beta-cypermethrin (BCP) or myclobutanil (MC) at the concentration of 20 mg/kg body weight (bw). The results showed that pesticides could induce changes in enzymatic activities (SOD, CAT, LDH, AChE) and MDA levels in organs or tissues of lizards. BCP could cause more severe oxidative damage than that of MC. Salivary enzymes activities showed sensitivity changes to the toxicity of pesticides. We could use saliva to reflect whether the reptiles are toxic by pesticides. We also agree that buccal swabs could be used as a tool for saliva sampling.

Eleven polymorphic microsatellite loci are described for the multi-ocellated racerunner Eremias multiocellata (Squamata: Lacertidae). Loci were screened in 33 individuals of E. multiocellata. The number of alleles ranged from 11 to 17. The observed heterozygosity ranged from 0.515 to 0.939, and the expected heterozygosity from 0.875 to 0.925. These microsatellite markers provide a valuable set of tools for population genetic studies of E. multiocellata.

In recent years, serious environmental pollution has caused a decrease in the abundance of many species worldwide. Reptiles are the most diverse group of terrestrial vertebrates. There are large amounts of toxicological data available regarding myclobutanil, but the adverse effects of myclobutanil on lizards has not been widely reported. In this study, treatment groups were orally administered a single-dose of myclobutanil (20mg/kg body weight (bw)). Subsequently, it was found that there were differences in myclobutanil levels between the different tissues and concentrations also changed with degradation time. The tissue concentrations of myclobutanil decreased in the order of: stomach > liver > lung > blood > testis > kidney > heart > brain. Based on our results, the liver and testis were considered to be the main target organs in lizards, indicating that the myclobutanil could induce potential hepatic and reproductive toxicity on lizards. Meanwhile, it was also demonstrated that the toxic effects of myclobutanil was different in different species, and the distribution of different pesticides in lizards were different.

Soil contamination caused by the widespread use of pesticides is one of the main environmental problems facing conservation organizations. (S)-metolachlor (SM) is a selective pre-emergent herbicide that poses potential risks to soil-related organisms such as reptiles. The present study elucidated the toxic effects of SM (3 and 30 mg/kg soil weight) in Eremias argus. The results showed that growth pattern was similar between the sexes in breeding season. For males, both kidney coefficient (KC) and testis coefficient in the exposure group were significantly different from those in the control group, while only KC in the high-dose group was significantly higher for females. Based on histopathological analysis, the livers of female lizards were more vulnerable than those of males in the exposure group. A reduction in total egg output was observed in SM exposed lizards. Accumulation studies indicated that skin exposure may be an important route for SM uptake in E. argus, and that the liver and lung have strong detoxification abilities. In addition, the body burdens of the lizards increased with increasing SM concentration in the soil.

Beta-cypermethrin (BCYP), a synthetic pyrethriod (PYR) pesticide which is a mixture of the alpha- and theta- cypermethrin, have been reported various toxicological profiles to non-target organisms. But little is known about assimilation, accumulation and toxic effects of BCYP in reptiles. The present study firstly elucidated absorption, tissue distribution, excretion of BCYP in Eremias argus . Treated group were administered orally with BCYP 20 mg/kg body weight (bw) dissolved in corn oil. Neurotoxicity was observed at 24 h after gavage, and the poisoning symptom ameliorated at 72 h. The changes of BCYP concentration depended on degradation time and tissues. Lizards had a strong capacity to eliminate BCYP with different tissue distribution. The tissues concentration of BCYP from high to low were intestine, stomach, heart, kidney, blood, lung, liver and brain. Bimodal phenomena were observed in lung, liver and kidney. These results may be due to the activities of enzymes, circadian rhythm, and enterohepatic circulation in lizards. Based on the results of organ coefficient and histopathology analysis in liver, the liver was confirmed as the main target organ.

Sexual dimorphism, age and geographical variability of 254 specimens of Eremias velox from 20 localities of Kazakhstan and Uzbekistan were studied. Sexual dimorphism found to be clearly manifested in some metric characters, amount of abdominal shields and peculiarities of preanal region pholidosis. It is suggested to use males for the examining of ecological relations, as they demonstrate more adaptive peculiarities of given characters, whereas females are more suitable for phylogenetic analysis. Some peculiarities of age variability are demonstrated. Cline variability is shown from west to east for the following characters: body length, head length, head width, rear limb length. The rate of cline variability is less in Alakol Depression. Females, however, demonstrated the decreasing of body length meaning from west to east. The largest body size in South-East Kzyl-Kum population suggesting, probably, that the most favorable conditions for this species is located in the region mentioned. Contrary, the conditions in the Alakol Depression are less favorable. Variations of coloration are described for E. velox. It is shown that the specter of head pholidosis is distinct from other species within Eremias genus, having 1-7 scales in between of parietal and interparietal shields. Eastern Kazakhstan populations are distinct from others by several characters, including peculiarities of pholidosis.

407 specimens of Eremias arguta, 140 specimens of E. intermedia and 271 specimens of E. velox from Kazakhstan and adjacent areas were examined in respect of pholidosis variability. 24 pholidosis characters of head and preanal region and 2 pholidosis characters of rear limbs were analyzed. Resulting from analysis, we divide E. arguta into three main groups. First group comprises animals from Volgograd District (Russia) and, partially, animals from Western Kazakhstan. Second group includes the rest of Western Kazakhstan samples, North Aral Sea Region, Eastern Kazakhstan and some specimens from Semirechje. Specimens from Kzylkum sands, Karatau ridge and environs of Kopa station were referred to as third group. The rate of specimens with increased amount of shields before the 2nd supraocular shield trends to gradual grow westward and southward. E. intermedia shows no significant differences within range of species distribution in Kazakhstan. Most variable E. velox from Western Kazakhstan are characterized with absente or only single scute between frontal and supraocular shields. Most variable temporal region were documented for eastern samples.

Es wurde die externe Morphologie von Eremias arguta in Kasachstan untersucht. Analysiert wurden drei metrische und zehn meristische Merkmale sowie die Dorsalzeichnung von 206 Individuen aus 13 Populationen in Süd-, Südost- und Ost-Kasachstan. Ein Geschlechtsdimorphismus wurde bei den Merkmalen relative Schwanzlänge (♀♀ > ♂♂), Anzahl der Femoralporen (♀♀ < ♂♂) sowie Anzahl der Gularia entlang der Kehlmitte (♀♀ < ♂♂) festgestellt. Bei einigen Merkmalen (Anzahl Dorsalia, Gularia, Femoralporen, Schuppenzahl zwischen den beiden Femoralporenreihen) besteht eine klinale Variation. Die meisten der Stichproben weisen ein Zeichnungsmuster aus großen, weißen, unregelmäßigen Flecken und einer dunklen Querstreifung auf. In Ost-Kasachstan treten dagegen Individuen auf, die kleine weiße Flecken und eine dunkle unregelmäßige zusammenfließende Querstreifung besitzen. Die Tiere der südlichsten Stichproben haben dagegen längliche weiße und unregelmäßige schwarze Flecken. Die systematische Position der ost-kasachischen Populationen ist nicht deutlich und benötig weitere Untersuchungen. Südost-kasachische Populationen gehören dagegen zu E. a. potanini, süd-kasachische Populationen zu E. a. uzbekistanica.

In Dobrudja we encountered 10 species of amphibians (Triturus dobrogicus, Bombina bombina, Hyla arborea, Pelobates fuscus, Pelobates syriacus, Bufo bufo, Bufo viridis, Rana dalmatina, Rana ridibunda, Rana lessonae), 16 species of reptiles (Emys orbicularis, Testudo graeca, Ablepharus kitaibelli, Lacerta agilis, Lacerta viridis, Lacerta trilineata, Podarcis taurica, Podarcis muralis, Eremias arguta, Coronella austriaca, Zamensis longissimus, Elaphe quatuorlineata, Dolichophis caspius, Natrix natrix, Natrix tessellata, Vipera ammodytes) and also Rana kl. esculenta populations. Some species of amphibians (Pelobates fuscus, Pelobates syriacus) that were only previously known inform the lower regions of the Danube’s meadow and in the vicinity of the Black Sea, were recorded in the high areas of northern Dobrudja. Also here, all three forms of the green frogs’ complex documented for Romania have been encountered, but Rana lessonae and Rana esculenta are very rare, being found only in the north. The central sectors of Dobrudja are severely impacted by human activities, almost completely cleared as a result of agriculture and showed very low number of herpetofauna species as being present. The most important areas for the herpetofauna are the northern and south-western regions.

This paper analyzed the morphological differences among the 8 Eremias species distributed in China.258 specimens were collected and measured.15 countable characters were selected to principal component analysis of data reduction.Based on the loudings of the first three principal components, scatterplots were figured out for further analysis.The results showed that 8 species located in three different regions in the scatterplots.They were E. argus species group (E. argus and E. brenchleyi), E. velox species group (E. velox and E. vermiculata), and E. multiocellata species group (E. multiocellata, E. arguta, E. przewalskii and E. grammica).The main differences between E. argus species group and other two species groups were presented on fn、pfa、scc、nvll and fprs, and it indicated that E. argus and E. brenchleyi were distinctly different from other species of Eremias.E. velox species group could be distinguished from E. multiocellata species group mainly by the character vbfp.The character pfa was found unstable in E. argus, and in 107 specimens there are five types on the numbers of prefrontal and most of them have 4 prefrontals.This article suggested that the character of prefrontal in E. argus was in the stage of intensive evolution, which indicated the formatting of new subspecies of E. argus.This research also agreed that E. quadrifrons Strauch (1876) was an invalid species.The character sisl could be used to distinguish E. argus from E. brenchleyi, which was regarded as a valid species and this character was treated as the difference to classify different species.E. velox and E. vermiculata could be easily distinguished by the characters nvll and clov.The character oa indicated E. grammica should be a group independent among all 8 species.The research showed that the difference between E. m. yarkandensis and E. m. multiocellata was sisl and larger than the differences in E. m. multiocellata、E. arguta and E. przewalskii.We speculated that E. m. yarkandensis should be a valid species but not a subspecies of E. multiocellata.E. m. multiocellata and E. przewalskii were so similar that it was difficult to distinguish them by morphological countable characters.We doubted the validity of the E. przewalskii.Finally based on the results of this research, 8 species were divided into four species groups: E. argus group (E. argus and E. brenchleyi), E. velox group (E. velox and E. vermiculata), E. multiocellata group (E. multiocellata, E. arguta and E. przewalskii), and E. grammica group.

The reptile and mammals fauna of North-East of Iran were investigated and the
contraction and fragmentation of some species due to climatic changes and human
activities were analyzed. The sampling was carried out in selected stations throughout
the Great Khorsan. The results showed that there are approximately 71 reptiles
(including 39 species of lizards, 32 snakes and one turtle) and 83 species of mammals.
The exact number of vulnerable and threatened reptile and mammal species in Khorasan
provinces is not clear, but there are at least 33 reptiles and 10 mammals categorized as
threatened species. The distribution and population size of some species has greatly
changed during recent years, most probably as a result of recent global warming, i. e.
temperature rise, decrease of precipitation, drought and human harmful activities. The
human activity in this region, especially urbanization, agricultural activities and cutting
of shrubs has caused fragmentation and serious decline of population size in some
species and even elimination of some local endemic population of relict species. The
conservation of mammals and reptiles in the North-East of Iran demands organized
collaborations including education of native people for protection of valuable vertebrate
faunae of the area.

The effects of the degree of urbanization on the composition and mean abundance of helminth species and the structure of helminth communities in the Mongolian racerunner were investigated along a rural–urban gradient in the region of Ulan-Ude city (the Republic of Buryatia, Russia) and neighbouring rural districts. Racerunners were obtained from key areas and categorized into three grades based on the degree of urbanization. In this study, a total of 208 lizards were examined. The helminth communities in the Mongolian racerunner were studied at the infracommunity and component community levels. The nematode Spauligodon pseudoeremiasi was a sensitive bioindicator of the degree of urbanization in our study. All parameters of helminth infracommunities in the Mongolian racerunner were significantly reduced with increasing degree of urbanization of the key areas. Two parameters of helminth component communities (the proportion of hosts infected with parasites and the Shannon index) were significantly reduced with increasing degree of urbanization. The decline recorded in parameters of helminth infracommunities and component communities in the Mongolian racerunner were probably connected with the attenuation of the relationships between helminths, having a complex life cycle with intermediate hosts along the rural–urban gradient.

New finds of the lizards of Eremias multiocellata complex became known for extreme southeast of Kazakhstan. In 2006-2007 re recorded the lizards in the mountain valleys of Kegen and Tekes Rivers creossing an intermountain depression located between Ketmen’ and Terskey-Alatau at altitude 1850-1950 m a.s.l. Morphological analysis revealed the reliable differences of the specimens collected from other species of multiocellata complex inhabited the close areas – E. stummeri from Issyk-Kul’ Depression and E. kokshaaliensis from Sary-Dzhaz River Basin of Kyrgyzstan. Morphological peculiarity of the populations recorded may be caused by their isolative position in extreme southeast of Kazakhstan and needs future elucidation.

We have studied the terrestrial reptile fauna of the northwest Yazd province (Iran) and present here some of the characters that we examined for common species in the region. In total, 50 specimens from eight families (six lizard families and two snake families) were collected from the region. The collected lizards belonging to 13 species were Laudakia nupta, Phrynocephalus maculatus, Phrynocephalus scutellatus, and Trapelus agilis (Agamidae); Agamura persica and Bunopus crassicaudus (Gekkonidae), Teratoscincus bedriagai (Sphaerodactylidae); Eremias fasciata, Eremias persica, Mesalina watsonana, and Ophisops elegans (Lacertidae); Varanus griseus (Varanidae), and finally Uromastix asmussi belonging to the Uromastycidae. The two species of snakes were Spalerosophis diadema schiraziana (Colubridae) and Psammophis schokari (Lamprophiidae). Based on these results, Agamidae and Lacertidae are the families with highest number of genera and the genera Eremias and Phrynocephalus had the most species. Among the collected lizards, Trapelus agilis, Mesalina watsonana, and Bunopus crassicaudus were the most abundant species in the northwest Yazd province.

A specially optimized restriction analysis of
highly repetitive DNA elements, called DNA taxonprint,
was applied for phylogenetic study of primates and lizards.
It was shown that electrophoretic bands of DNA
repeats revealed by the taxonprint technique have valuable
properties for molecular systematics. Approximately
half of taxonprint bands (TB) are invariable and
do not disappear from the genomes during evolution or
change spontaneously. Presumably these invariable
bands are restriction fragments of dispersed DNA repeats.
Another group represents variable taxonprint
bands that differ even between closely related species.
These variable bands are probably represented by tandem
DNA repeats and could be used as species-specific
markers. It was shown that taxonprint bands are independent
characters since the appearance of a new taxonprint
band does not change the previous band pattern.
Phylogenetic reconstruction carried out on taxonprint data
demonstrated that this approach could be of general utility
for molecular systematics and species identification.

A phylogeny of the family Lacertidae was derived from mtDNA gene sequence data. Seventeen species, representing 16 currently recognized genera and subgenera, were included in the analysis. A total of 954 bp was obtained and aligned from 12S and 16S partial gene sequences. A preferred tree was selected based on weighted parsimony and functional ingroup and outgroup analyses. Decay analysis, bootstrapping, and permutation tail probability were used to evaluate support for the recovered nodes. The genus Gallotia was resolved as the basal taxon and the sister group of all remaining lacertids.Takydromus branched off next. All African lacertids grouped together and formed a monophyletic clade with the Eurasian genera Eremiasand Ophisops. The remaining Eurasian lacertids sequentially branched off near the base of the tree in a “comb-like” fashion. The basal position of Gallotia and the monophyly of African lacertids are consistent with previous hypotheses. The European-origin hypothesis of lacertids is favored, and the distribution of lacertids in Africa is likely a Miocene dispersal event. Most of the extant European lacertids probably arose after the Eocene. The classification of the family needs to be revised.

A phylogeny of the family Lacertidae was derived from DNA sequences of six mitochondrial genes. Only a few nodes were confidently resolved using maximum parsimony, although the data yielded a total of 1664 phylogenetically informative characters. The lacertids grouped into two subfamilies, the Gallotiinae which includes genera Gallotia and Psammodromus, and the Lacertinae which includes the remaining lacertids. The Lacertinae split into two additional groups. The African group included all African and Arabian lacertids and two Eurasian genera, Eremias and Ophisops; the remaining Eurasian lacertids were included in the Eurasian group. Most of the relationships within the African and Eurasian groups cannot be confidently resolved. A permutation tail probability test suggested that there is very little character covariance in the data to support these unresolved relationships. A recent explosive speciation hypothesis was invoked to explain the lack of structure of the data. The common ancestor of the Eurasian group, as well as the ancestor of the African group, experienced simultaneous, or almost simultaneous, multiple speciation events, which left none or very few characters fixed on the internodes. The phylogenetic reconstruction at the family level will be very difficult, if not impossible. Future phylogenetic research should focus on lower levels.

It is known that parasitic worms are an integral part of the natural ecosystem, performing a complex regulatory function. The aim of our study was to investigate the pathological changes that occur in the tissues of lizards exposed to parasites. In histological specimens of small intestine we observed cross sections of nematodes. The bodies of parasites with vaguely expressed organ structure and rounded formations of a small size, were surrounded by a wide strip of acellular eosinophilic mass; in the central parts there was a single rounded basophilic inclusion. On this basis we can assume that there is a formation of fibrosis, a protection against the parasite. Intestinal nematode parasitism in the studied lizards causes building of a xenoparasite barrier. The formation of the xenoparasite barrier is due to the adaptation of a parasitic agent and the host.

The present paper proves that the endangered steppe runner (Eremias argutadeserti) still exists in the “Hanu Conachi River Sand Dunes” Nature Reserve. Prior to thisstudy it had not been recorded for almost 40 years and had been reported as extinct inthis region by the Romanian Red Data Book of Vertebrates. However, the majority of itsnatural habitat has been destroyed by the Robinia pseudoacacia plantations from thereserve. In order to ensure the survival of Eremias arguta deserti in the reserve, and inRomanian Moldavia, urgent measures have to be taken to reconstruct its natural habitatthrough the development of a management plan under the supervision and guidance ofexperts. At present, the steppe runner population from Hanu Conachi is extremelythreatened.

Iran contains 36 named endemic reptile species in 17 genera and seven families. The
most endemic and speciose family is the Gekkonidae, followed by the Lacertidae. These
two families collectively dominate with 22 species (or 60.1%) of the total endemic
herpetofauna. Twenty one endemics are known only from a single location or restricted
area within a single physiographic region. An analysis of endemicity is given in terms of
systematics and distribution.

The tail regeneration frequency in 55 lizards from the Volgograd region was analyzed, among which were 12 steppe-runners (Eremias arguta (Pallas, 1773)) and 43 sand lizards (Lacerta agilis Linnaeus, 1758). The following cases of tail regenerates were observed: 0) a normal tail; 1) regeneration in the distal third; 2) a tail regenerated from the middle part; and 3) autotomy near the base (the proximal third). The majority of the lizards had normal tails (60.0% of E. arguta and 83.2/57.1% of L. agilis in females/males). Only 16.7% of the steppe-runners had regenerated tails in the distal part whereas 8.4% of females and 28.6% of males had autotomy with subsequent regeneration in the proximal third of the tail; 5.6% of females and 14.3% of males had regenerated autotomy in the distal part, and 2.8% of females had it in the middle part of the tail. Two lizards with bifurcated tails were found and described: a male of E. arguta and a female of L. agilis. A case of complicated abnormality of tail regeneration in a male of L. agilis is also described.

Приводится анализ частоты регенерации хвоста у 55 ящериц, из которых 12 особей разноцветной ящурки (Eremias arguta (Pallas, 1773)) и 43 - прыткой ящерицы (Lacerta agilis Linnaeus, 1758) из Волгоградской области. Наблюдались следующие случаи наличия регенератов хвоста: 0) нормальный хвост; 1) регенерация в дистальной трети; 2) хвост регенерирован из середины хвоста; 3) автотомия вблизи основания (проксимальной трети). Большинство ящериц имело нормальные хвосты (60.0% E. arguta и 83.2/57.1% L. agilis самки/самцы). Лишь 16.7% особей разноцветной ящурки были с регенерированными хвостами в дистальной его части, тогда как у 8.4% самок и 28.6% самцов произошла автотомия с последующей регенерацией в проксимальной трети хвоста; у 5.6% самок и 14.3% самцов - в дистальной части и у 2.8% самок посередине хвоста. Выявлено и описано две особи с бифуркацией хвоста: один самец E. arguta и одна самка L. agilis. Также описан случай сложного нарушения регенерации хвоста у самца L. agilis. Рентгенографическое исследование показало, что каудальная бифуркация может возникать как результат первичной, так и вторичной (на хрящевой трубке) регенерации.

Multiple band patterns of DNA repeats in
the 20–500-nucleotide range can be detected by digesting
genomic DNA with short—cutting restriction endonucleases,
followed by end labeling of the restriction
fragments and fractionation in nondenaturing polyacrylamide
gels. We call such band patterns obtained from
genomic DNA ‘‘taxonprints’’ (Fedorov et al. 1992).
Here we show that taxonprints for the taxonomic groups
studied (mammals, reptiles, fish, insects—altogether
more than 50 species) have the following properties: (1)
All individuals from the same species have identical taxonprints.
(2) Taxonprint bands can be subdivided into
those specific for a single species and those specific for
groups of closely related species, genera, and even families.
(3) Each restriction endonuclease produces unique
band patterns; thus, five to ten restriction enzymes (about
100 bands) may be sufficient for a statistical treatment of
phylogenetic relationships based on polymorphisms of
restriction endinuclease sites. We demonstrate that taxonprint
analysis allows one to distinguish closely related
species and to establish the degree of similarity among
species and among genera. These characteristics make to use this phenomenon for phylogenetic aims (Cooke
1975; Christie and Skinner 1979; Brown and Dover
1979, 1980; Elizur et al. 1982; Hembelen et al. 1982;
Buckland 1983; Dandieu et al. 1984; Lima de Faria et al.
1984; Shubina and Mednikov 1986; Turner et al. 1991),
but this approach has not been extensively applied. In
this paper we have reexamined the problem on the basis
of our own preliminary results, partly published in Russian
journals, confirming the ideas about possible correlations
between evolution of DNA repeats and speciation
(Fedorov et al. 1992; Grechko et al. 1993; Potapov and
We have demonstrated that the modified method designated
‘‘DNA taxonprint’’ (Fedorov et al. 1992) can be
effectively used for revealing species—specific genomic
markers in different taxonomic groups. These taxonprint
markers are found to be helpful for evaluation of the
degree of species similarity between species, genera, and
families. More than 50 species from different taxa were

Eremias, or racerunners, is a widespread lacertid genus occurring in China, Mongolia, Korea, Central Asia, Southwest Asia and Southeast Europe. It has been through a series of taxonomic revisions, but the phylogenetic relationships among the species and subgenera remain unclear. In this study, a frequently studied region of the mitochondrial 16S rRNA was used to (i) reassess the phylogenetic relationships of some Eremias species, (ii) test if the viviparous species form a monophyletic group, and (iii) estimate divergence time among lineages using a Bayesian relaxed molecular-clock approach. The resulting phylogeny supports monophyly of Eremias sensu Szczerbak and a clade comprising Eremias, Acanthodactylus and Latastia. An earlier finding demonstrating monophyly of the subgenus Pareremias is corroborated, with Eremias argus being the sister taxon to Eremias brenchleyi. We present the first evidence that viviparous species form a monophyletic group. In addition, Eremias przewalskii is nested within Eremias multiocellata, suggesting that the latter is likely a paraphyletic species or a species complex. Eremias acutirostris and Eremias persica form a clade that is closely related to the subgenus Pareremias. However, the subgenera Aspidorhinus, Scapteira, and Rhabderemias seem not to be monophyletic, respectively. The Bayesian divergence-time estimation suggests that Eremias originated at about 9.9 million years ago (with the 95% confidence interval ranging from 7.6 to 12 Ma), and diversified from Late Miocene to Pleistocene. Specifically, the divergence time of the subgenus Pareremias was dated to about 6.3 million years ago (with the 95% confidence interval ranging from 5.3 to 8.5 Ma), which suggests that the diversification of this subgenus might be correlated with the evolution of an East Asian monsoon climate triggered by the rapid uplift of the Tibetan Plateau approximately 8 Ma.

We used the Mongolian racerunner Eremias argus as a model animal to evaluate the effects of constant versus fluctuating incubation temperatures on hatching success and hatchling phenotypes. Eggs were incubated under four constant [24, 27, 30 and 33 (±0.3) °C] and one fluctuating temperature regimes. Hatching success did not differ among treatments, and incubation temperature did not affect the sexual phenotype of hatchlings. Incubation length decreased exponentially as incubation temperature increased, and eggs incubated at fluctuating temperatures took a longer time to complete development than did those incubated at constant temperatures with the same mean. Of the hatchling phenotypes examined, body dry mass, carcass dry mass, residual yolk dry mass and locomotor performance of hatchlings were more likely to be affected by incubation temperature. Overall, locomotor performance was best in the low temperature treatments (24 °C and 27 °C) and worst in the high temperature treatment (33 °C), with the moderate temperature treatments (30 °C and fluctuating temperatures) in between. Our data show that: (1) daily exposure of eggs to extreme temperatures that are potentially lethal to embryos for brief periods does not have detectable adverse effects on hatching success and morphological phenotypes in E. argus; and (2) thermal fluctuations exert no positive effects on locomotor performance of hatchlings but influence incubation length differently than constant temperatures with the same mean.

Enantioselective toxicokinetics, accumulation, and toxicity of myclobutanil were investigated by oral exposure of myclobutanil enantiomers to lizards. After a single oral administration, the absorption half-lives () and elimination half-lives () were in the range of 0.133–14.828 and 3.641–17.682 h, respectively. The absorption and elimination half-lives of (+)-myclobutanil showed no significant differences from those of (-)-myclobutanil in lizard blood, whereas preferential enrichment of (-)-enantiomer was observed in the liver, fat, skin, intestine, lung and kidney. In the bioaccumulation experiments, the residue of (-)-myclobutanil was detected in most tissues at 7, 14, and 28 days, while (+)-myclobutanil was found only in lizard skin, at a concentration lower than that of (-)-myclobutanil. Thus, (-)-myclobutanil was preferentially accumulated in lizards. The transcriptional responses of metabolic enzyme genes indicated that cytochrome P450 1a1 (cyp1a1), cyp2d3, cyp2d6, cyp3a4 and cyp3a7 played a crucial role in the metabolism of (+)-myclobutanil, whereas cyp1a1, cyp2d3, cyp2d6, cyp2c8, and cyp3a4 contributed to the metabolism of (-)-myclobutanil. The difference in metabolism pathways may be a reason for the enantioselectivity of myclobutanil in lizard. Myclobutanil also affected the expression of antioxidant enzyme genes, and the (+)-myclobutanil treatment might produce higher oxidative stress in lizard liver when compared with its antipode. Hepatic histopathological changes such as hepatocellular hypertrophy, nuclear pyknosis, vacuolation, and non-zonal macrovesicular lipid accumulation were observed in the liver of lizards for both (+)-myclobutanil and (-)-myclobutanil treatments. Thus, myclobutanil could affect lizard liver upon multiple exposure. The findings of this study provide specific insights into the enantioselective metabolism and toxicity of chiral triazole fungicides in lizards.

DNA sequences from parts of the 12S, 16S and cytochrome b mitochondrial genes, which totalled 1049 aligned base pairs, were used to estimate the relationships of 49 species of Lacertidae, including representatives of 19 out of the 23 recognized genera and 23 species of the paraphyletic genus Lacerta. These data were used, together with morphological information, to estimate the relationships within the family. Molecular evidence corroborates the monophyletic status of many genera and species groups originally based on morphology. It indicates that Psammodromus forms a clade with Gallotia, which is the sister taxon of all other lacertids. These comprise three units: the primarily Afrotropical armatured group; the largely Oriental Takydromus; and the west Palaearctic Lacerta and its derivatives, Podarcis and Algyroides. Morphology also supports the first three assemblages, but suggests that they are derived from a paraphyletic Lacerta. Within Lacerta and its allies, DNA sequence analysis corroborates the affinity of some members of each of the subgenera Lacerta s. str. and Timon, and of the L. saxicola group. It also supports the relationship of L. monticola, L. bonnali and L. horvathi, and suggests that the L. parva–L. fraasi clade and L. brandti are not related to Psammodromus–Gallotia, as morphology indicates, but instead are associated respectively with the L. danfordi and L. saxicola groups. DNA sequence data provide additional evidence that the eastern Arabian `Lacerta` jayakari and `L.` cyanura are members of the armatured clade and also sister species. Our analysis supports an origin for present lacertids in west Eurasia. The armatured clade invaded Africa, probably in the mid-Miocene, spreading widely and evolving increasingly xeric-adapted forms, one lineage of which later moved back into the Palaearctic. `Lacerta` jayakari and `L.` cyanura are assigned to Omanosaura, Lutz and Mayer 1986. The name Gallotiinae Cano, Baez, Lopez-Jurado and Ortega, 1984 is available for the Gallotia–Psammodromus clade, Eremiainae Shcherbak 1975 for the armatured clade and Lacertinae for Lacerta, Podarcis and Algyroides. Two new subgenera of Lacerta are proposed here: Caucasilacerta for L. saxicola and its allies, and Parvilacerta for L. parva and L. fraasi.

Den Iran als Urlaubsziel zu wählen, dies dürfte wohl den wenigsten Deutschen einfallen. Dabei verfügt dieses riesige Land über eine reichhaltige Kultur und ist auch unter herpetologischen Gesichtspunkten sehr interessant. Andererseits bietet der Iran fast keine touristische Infrastruktur und ist dem Tourismus auch nicht wirklich aufgeschlossen - angefangen dabei, dass Kreditkarten nicht akzeptiert werden, bis hin zur Kopftuchpflicht für alle Frauen, egal welcher Nationalität oder Glaubensrichtung sie angehören. Dies alles schreckte uns jedoch nicht davon ab, per Fahrrad ca. 3600 Kilometer von Istanbul bis nach Tehran zu fahren, weitestgehend entlang der alten Seidenstrasse.

The evolutionary diversification of many terrestrial vertebrate groups is strongly linked to climatic events in the Cenozoic, the period from 65 Million years ago to today when modern animals first appeared. I investigated the effects of Cenozoic climate change on the taxonomic and morphological diversification of the Old World lizard family Lacertidae, with particular emphasis on the African radiation. African lacertids exhibit an unusual pattern of diversification, in which their highest species richness occurs in deserts north and south of the equator, despite being spread throughout the continent. This disparity is particularly surprising given that desert lacertids are thought to be evolutionarily younger than their mesic-dwelling relatives, suggesting increased diversification rates in arid habitats. To identify the evolutionary factors underlying this pattern, I use a combination of phylogenetic, morphological and ecological techniques. In Chapter 1, I apply Bayesian methods and fossil-based calibrations to molecular sequence data to construct a time-calibrated phylogeny for Lacertidae. I estimate that the family arose in the early Cenozoic, with the majority of their African radiation occurring in the Eocene and Oligocene. In Chapter 2, I describe changes in lacertid body shape across biomes and substrates, and find widespread morphological convergence in similar habitat types. I suggest that in addition to foraging demands, fluctuating and extreme climatic conditions, largely driven by precipitation and temperature, contribute to morphological convergence across independent arid-dwelling clades. Finally, I test if ancestral transitions in ecology, morphology, and rates of diversification temporally coincide with paleoclimatic events in the Cenozoic. I use High Resolution X-ray Computed Tomography to characterize changes in the skull related to life in arid habitats, and apply maximum likelihood methods to test if the origins of those traits temporally coincide with significant shifts in habitat, diversification rates and climatic changes. My results show that African lacertids experienced three major peaks in diversification, accompanied by the evolution of suites of arid-adapted morphological traits. These changes coincide with climatic shifts in Africa, including the transition from closed forests to open grasslands and savanna in the late Oligocene, prior to the peak temperatures of the mid-Miocene Climatic Optimum, and following the formation of the Benguela current leading to hyper-aridity in southern Africa. I conclude that deserts are important centers for reptile evolution, but that expected changes in climate due to global warming may outpace the ability of arid-dwelling species to adapt and persist in the future.

Background: Although current molecular clock methods offer greater flexibility in modelling
evolutionary events, calibration of the clock with dates from the fossil record is still problematic
for many groups. Here we implement several new approaches in molecular dating to estimate the
evolutionary ages of Lacertidae, an Old World family of lizards with a poor fossil record and
uncertain phylogeny. Four different models of rate variation are tested in a new program for
Bayesian phylogenetic analysis called TreeTime, based on a combination of mitochondrial and
nuclear gene sequences. We incorporate paleontological uncertainty into divergence estimates by
expressing multiple calibration dates as a range of probabilistic distributions. We also test the
reliability of our proposed calibrations by exploring effects of individual priors on posterior
Results: According to the most reliable model, as indicated by Bayes factor comparison, modern
lacertids arose shortly after the K/T transition and entered Africa about 45 million years ago, with
the majority of their African radiation occurring in the Eocene and Oligocene. Our findings indicate
much earlier origins for these clades than previously reported, and we discuss our results in light
of paleogeographic trends during the Cenozoic.
Conclusion: This study represents the first attempt to estimate evolutionary ages of a specific
group of reptiles exhibiting uncertain phylogenetic relationships, molecular rate variation and a
poor fossil record. Our results emphasize the sensitivity of molecular divergence dates to fossil
calibrations, and support the use of combined molecular data sets and multiple, well-spaced dates
from the fossil record as minimum node constraints. The bioinformatics program used here,
TreeTime, is publicly available, and we recommend its use for molecular dating of taxa faced with

While global variation in taxonomic diversity is strongly linked to latitude, the extent to which morphological disparity follows geographical gradients is less well known. We estimated patterns of lineage diversification, morphological disparity and rates of phenotypic evolution in the Old World lizard family Lacertidae, which displays a nearly inverse latitudinal diversity gradient with decreasing species richness towards the tropics. We found that lacertids exhibit relatively constant rates of lineage accumulation over time, although the majority of morphological variation appears to have originated during recent divergence events, resulting in increased partitioning of disparity within subclades. Among subclades, tropical arboreal taxa exhibited the fastest rates of shape change while temperate European taxa were the slowest, resulting in an inverse relationship between latitudinal diversity and rates of phenotypic evolution. This pattern demonstrates a compelling counterexample to the ecological opportunity theory of diversification, suggesting an uncoupling of the processes generating species diversity and morphological differentiation across spatial scales.

In north Khorasan province, Iran, we compared the effectiveness of two types of traps for collecting reptiles: funnel traps and pitfall traps. Three stations were monitored over three 10-day periods and in total 544 individuals (including 200 re-captures) belonging to 5 species and 4 families of lizards (Lacertidae) were collected. Funnel traps with 280 captures were more efficient than pitfall traps with 264 captures, but the differences between the two traps are not significant. Three species were captured most often in the three different stations respectively: station 1, Bunopus crassicauda (22% relative frequency); station 2, Eremias fasciata (29% relative frequency); and station 3, Trapelus agilis (32% relative frequency). Shannon species richness indices were higher for pitfall than funnel traps (i.e., 1.45 vs. 1.40), but the difference was not significant. Pitfall traps were better for capturing species that search widely for food, while the funnel traps preferentially captured species that climb plants, such as Trapelus agilis. We recommend using both types of trap to capture the various types of species in any one region.

Eremias strauchi strauchi and Eremias strauchi kopetdaghica are genetically and morphologically distinct and are distributed allopatrically in northeastern and northwestern Iran. E. s. strauchi is distinguishable by having green spots on lateral parts of the body, while E. s. kopetdaghica is characterized by white spots and irregular black dots on lateral parts of the body. Recent molecular studies have suggested that these are two distinct species, but other types of analyses leave their classification unclear. In this study, we evaluated their taxonomic status using additional data (including ecological niches) to confirm the hypothesis that they are two species. All known records of their occurrence were employed to predict and evaluate the suitable areas where they may be expected to be found in Iran. We then performed niche similarity tests (niche identity and background tests) and point-based analyses to compare their ecological niches and explain ecological differentiation. Niche models of E. s. strauchi and E. s. kopetdaghica had good results and powerful performance based on high area under the curve (AUC) values [E. s. strauchi = 0.992, standard deviation (SD) = ± 0.008; E. s. kopetdaghica = 0.978, SD = ± 0.032]. Ecological differentiation has been found across the entire range, indicating that ecological differentiation had an important role in species differentiation. Environmental conditions for the species diverged along environmental variables, as precipitation of coldest quarter for the “Strauch” subspecies and precipitation of warmest quarter for the “Kopet dagh” subspecies were most important in determining habitat suitability, respectively. These two factors are important in niche differentiation between the two species and influenced their genetic divergence. Finally, our results confirmed the niche differentiation between E. s. strauchi and E. s. kopetdaghica and added new insights into the taxonomic distinction between E. s. strauchi and E. s. kopetdaghica.

Outbreaks of grasshoppers (Orthoptera: Acrididae) often cause serious ecological damage. Recently, there has been interest in using natural enemies of grasshopper for their biological control. This study examined the biology and predation on grasshoppers by Eremias argus, a common lizard in Inner Mongolia. Its developmental duration and life history are consistent with adaptation to grasshopper phenology. The diet structure of E. argus included grasshoppers, beetles, ants, leafhoppers, moths, bees and spiders. A positive correlation between E. argus population numbers and grasshopper population numbers was highly significant. We built models describing the functional response and intraspecific competition for E. argus adults. The functional feeding response of E. argus on grasshopper was classed as Holling type III. The maximum number of grasshoppers consumed by female and male adults were 11.2 and 7.0 individuals per day, respectively. Predatory ability was strongest in female adults, with the second and third instars of Oedaleusasiaticus preferred. The predation ratios(E) of E. argus on grasshoppers declined with increasing lizard density, especially for female adult E. argus. E. argus could play an important role in grasshopper control and maintaining a population of E. argus in the grassland ecosystem could effectively control low-density grasshopper populations on grassland. Suggestions on how E. argus could fit into an IPM programme for biological control of grasshopper are discussed.

The life and work of the Alsatian Louis Amédée Lantz (1886-1953), a pioneer of European herpetology. A trained and professional research-chemist, the Alsatian Louis Amédée Lantz was an active and particularly dynamic herpetologist. His residence of nearly twelve years in Russia enabled him to make several field trips to regions such as the Caucasus and Iran. He always carried with him a home made telescopic net that he used to catch lizards. That net became symbolic of Lantz for most people around him. He realized significant herpetological collections mainly deposited in the Museum of the Zoology Institute of the Russian Academy of Sciences in St. Petersburg. Soon after the Russian Revolution in 1917, he had to leave the country and stayed for a few years in France before joining England. During this period, Lantz visited the French Pyrenees and the Mediterranean border (Hyeres Islands, Bandol), enabling him to discover for the first time oviparous populations of common lizard and also to describe a new species of lizard from the French Pyrenees. Lantz is also at the origin of the discovery of unisexual reproduction by parthenogenesis in reptiles. His collaboration with the Swedish amateur herpetologist Otto Cyrén, whom he met through the German herpetologist Willy Wolterstorff, was particularly successful throughout his career. Lantz died at the age of 66 years, in Switzerland, as he was about to join the team of herpetologists at the Natural History Museum in Paris.

the Lacertidae is one of the most diverse and widespread lizard families throughout Eurasia and Africa. Several studies so far have attempted to unravel the phylogeny of Lacertidae using morphological and mole- cular data. However, the intra-family relationships remain unclear. in an effort to explore the phylogenetic relationships within the family Lacertidae, a concatenated dataset of 5727 bp from six genes (two nuclear and four mitochondrial) and 40 genera was assembled based on GenBank database. Phylogenetic inference analy- ses were conducted using Maximum Parsimony (MP), Bayesian inference (Bi) and Maximum Likelihood (ML), revealing that even a combined dataset of both mitochondrial and nuclear genes is not able to resolve the phylogenetic relationships of the Lacertidae family under the tribe level.

Information about the mating behaviors of an endangered species is critical for the understanding of the natural history of the species as well as in situ and ex situ breeding programs designed to rehabilitate field populations. We describe the mating behaviors of the Mongolian racerunner (Eremias argus), an endangered species in South Korea. The mating of this species consists of precopulatory, copulatory, and postcopulatory stages and is composed of 12 different mating behaviors. During the postcopulatory stage, other males or females not involved in mating show more interference behaviors than during the precopulatory and copulatory stages. The male E. argus has an extraordinarily long postcopulatory bite, which may function as a type of mate-guarding behavior. This study is the first report on the mating behavior of a South Korean reptile.

Information on habitat use is critical in sizing protected areas for endangered reptile species.To investigate habitat use,home range,and hibernaculum of the endangered Mongolian Racerunner (Eremias argus),we radio-tracked 40 specimens in a coastal sand dune in South Korea.Of the 163 locations recorded during the breeding season,150 (92.0％) were in grass sand dunes,and the rest (8.0％),all associated with the same lizard,were in shrub sand dunes.All of the 123 locations recorded during the non-breeding season were in grass sand dunes.No lizards were found in the grasslands abutting the dunes.The four lizards with identifiable hibernation sites were found under an average of 17.8 cm of sand and were all located in grass sand dunes.The lizards moved approximately 5 m daily and used 162 m2 of home range (computed by minimum convex polygon,MCP) during the breeding season,and they moved approximately 2 m and used 68 m2 of home range during the non-breeding season.However,the mean daily moved distances and MCP home ranges were not statistically significantly different between the seasons or between males and females.Our results suggest that in coastal sand dunes,E.argus uses grass sand dunes as its main habitat throughout the year.This finding could be used to determine the appropriate habitat size and to designate for the conservation of this endangered species.

In this study, we have evaluated the physical characteristics of neonate, female, and male Mongolian racerunners (Eremias
argus) and determined the age structure of a population of the species in a field located in Taean-gun, Chungnam,
South Korea. The physical parameters of females and males, including snout-vent length (SVL), head length, head width,
and body mass were found to be significantly interrelated. Male Mongolian racerunners exhibited significantly longer
heads than the females, but other physical parameters, such as SVL, head width, and body mass did not differ between
the female and male specimens. In the study population, the females ranged in age from two to eleven years old and the
males ranged between two to eight years of age. The number of females and males, when separated into different age
classes, did not differ within each age class. Male Mongolian racerunners evidenced greater SVL growth coefficients than
the females, but asymptotic SVL did not differ between the females and males.

We sequenced the mitochondrial genome of the Western green lizard (Lacerta bilineata) using Illumina technology and additional Sanger sequencing. The assembled 17 086 bp mitogenome had a GC content of 40.32% and consisted of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region (CR), with a gene order identical to the chordate consensus. In addition, we re-sequenced the mitogenome of the closely related Eastern green lizard L. viridis using the same techniques as for L. bilineata. The mitogenomes of L. bilineata and L. viridis showed a sequence identity of 94.4% and 99.9%, respectively, relative to the previously published L. viridis mitogenome. The phylogenetic reconstruction based on 17 Lacertinae mitogenomes using Anolis carolinensis as the outgroup supported L. bilineata and its sister species L. viridis as distinct lineages.

Summer counts of Phrynocephalus helioscopus (Pallas, 1771) and Eremias arguta (Pallas, 1773) were conducted in the Altai Region during April – September, 2016. A sharp decline in the activity of lizards in June and July was noted, due to the high temperatures and dry weather. As a result of excavation of some burrows, lizards in a non-active state were found. The possibility of summer hibernation (estivation) of the species is considered.

An overview of the cases of introduction (both accidental and intentional) of amphibians and reptiles in
the Caucasus and Crimea is provided. The introduction cases are systemized in accordance with the goals
and ways of introduction and with regards to the expected scale of the impact and its nature. No negative
consequences of the introduction of amphibian and reptile species in the Crimea and Caucasus are currently
observed on any of the known examples. No cases of species naturalization, which the “invasion”
term can be applied to, have been revealed. The importance of allochthonous populations as experimental
sites to study microevolutionary processes and ecological adaptations of the species in new environmental
conditions is discussed.

he chromosomes of eight lacertid species were studied by standard and banding techniques (C- and NOR-banding, telomeric sequences) and chromosomal interlocation during mitosis and meiosis was investigated. The data obtained are discussed in the light of modern ideas of the interrelation between DNA changes, karyotype evolution, and speciation. The assumption is voiced on the optimal number of arms and, consequently, the “optimal” number of functional telomeres in the Lacertidae, which in its turn may be associated with the structure of the nucleus and with canalization of the genome as a whole.

In the shrub land habitat,E.argus lives in the shrub community but P.frontalis lives mainly on the field among the shrub land. The overlap of their spatial niche was small ( 0.15) but the overlap of the trophic niche was high( 0.82, Aug.).The potential competitive ability between the two species was measured by Nelson similarity coefficient.The competitive ability of P.frontalis for space was stronger than that of E.argus,but for trophic E.argus was stronger than that of P.frontalis.Measured by several factors,the Adaptability of E.argus was superior to that of P.frontalis in the shrub land.

In this study we observed the embryonic development processes and compared the weight of eggs with neonates to identify the form of nutritional provisioning in Eremias multiocellata. We also used light microscopy to determine the features of chorioallontoic placenta during late stages of gestation. Neonatal dry weight was approximately 10.3% smaller than egg dry weight. Chorioallantoic membrane and uterine epithelium exhibited an indirect apposition without any fusion. No specialized region, placentome, has been found for nutrition transfer between these membranes. The chorioallontoic placenta of E. multiocellata is consistent with the simplest and most common type, Weekes type I. We infer that E. multiocellata is predominately lecithotrophic, meaning that nourishment for embryonic development is primarily supplied by the yolk. This kind of embryonic nutrition confirms the pattern found in most squamates with a simple placenta. This simple placenta adds anatomical evidence to understand the weak immune interaction between matrix and fetus in E. multiocellata. Finally, we discussed the implications for interpreting the evolution of viviparity and placentation.

Reproductive success and morphological traits are intimately linked in lizards. We collected adult multi-ocellated racerunners Eremias multiocellata from a population in Inner Mongolia (northern China) to quantify sexual dimorphism and female reproductive characteristics of this poorly studied viviparous, lacertid lizard, testing for the prediction that the evolution of sexual dimorphism is promoted by between-sex differences in reproductive success relating to adult morphological traits. Adults are sexually dimorphic in head size but not in body size, with males having longer and wider heads than do females of the same body length. Females ovulate from May to June and, under laboratory conditions, they give birth to young from late June to late July. Litter size ranges from two to four young. Litter mass is positively correlated with female SVL, but female SVL only explains a small portion (approximately 19%) of variation in litter mass. Both litter size and neonate mass are not correlated with female SVL. Neonate mass is negatively correlated with relative fecundity (litter size relative to female SVL), suggesting a trade-off between size and number of offspring in E. multiocellata. Overall, selective pressures towards large male and large females are both relatively weak in E. multiocellata, and the evolution of sexual dimorphism in head size results mainly from between-sex differences in reproductive success relating to adult head size

We compared adult size, female reproductive traits, and offspring phenotypes between multiocellated racerunners (Eremias multiocellata) from two thermally different sites (populations) in Inner Mongolia (North China): the colder one in Wulatehouqi (WQ) and the warmer one in Dalateqi (DQ). Both adults and neonates were smaller in the colder site. Females from the two sites both produced a single litter of 2–5 young per season, and did not differ in allocation of energy to reproduction after accounting for differences in body size. Female neonates had more ventral scales than did males, and the WQ neonates had fewer ventral scales than did the DQ neonates. The WQ neonates were slower than the DQ neonates. When body length was normalized across populations, we found that (1) hindlimb length correlated positively with sprint speed in both WQ and DQ neonates, (2) forelimb length correlated positively with sprint speed only in the DQ neonates, and (3) tail length correlated positively with sprint speed only in the WQ neonates. Hindlimb length played a more important role in locomotion than did tail length or forelimb length. Though differing in size and morphology, neonates from the two sites did not differ in early growth and survival under identical laboratory conditions. Our data are consistent with many studies that have shown countergradient variation in physiological traits (growth rate and reproductive output) and cogradient variation in morphological traits.

We used a cold-climate viviparous lacertid lizard (Eremias prezwalskii) as a model system to test the maternal manipulation hypothesis. Twenty-four gravid females collected from a population in Inner Mongolia (northern China) were maintained in the laboratory for the whole gestation length, with 12 allowed to bask for 14-h daily and the other 12 for 10-h daily. Females selected lower body temperatures but did not thermoregulate more precisely when gravid. The mean gestation length was shorter in females provided with longer basking opportunity. Neonates in the two treatments differed in tail length and the number of ventral scales but not in other examined morphological traits, with offspring born in the 14-h treatment having longer tails but fewer ventral scales. Offspring were sexually dimorphic at birth, with females being smaller in tail length, head length and fore-limb length but having more ventral scales than males of the same size. Offspring born in the 14-h treatment were not only faster runners but also grew faster than did offspring born in the 10-h treatment. Our data validate the main predictions of the maternal manipulation hypothesis that females should shift selected body temperatures during gestation to provide optimal thermal conditions for developing embryos and that phenotypic traits determined by maternal thermoregulation should enhance offspring fitness. Our study is the first to demonstrate that the maternal manipulation hypothesis applies to cold-climate viviparous reptiles.

We acclimated adult males of three Eremias lizards from different latitudes to 28 °C, 33 °C or 38 °C to examine whether temperature acclimation affects their thermal preference and tolerance and whether thermal preference and tolerance of these lizards correspond with their latitudinal distributions. Overall, selected body temperature (Tsel) and viable temperature range (VTR) were both highest in E. brenchleyi and lowest in E. multiocellata, with E. argus in between; critical thermal minimum (CTMin) was highest in E. multiocellata and lowest in E. brenchleyi, with E. argus in between; critical thermal maximum (CTMax) was lower in E. multiocellata than in other two species. Lizards acclimated to 28 °C and 38 °C overall selected lower body temperatures than those acclimated to 33 °C; lizards acclimated to high temperatures were less tolerant of low temperatures, and vice versa; lizards acclimated to 28 °C were less tolerant of high temperatures but had a wider VTR range than those acclimated to 33 °C and 38 °C. Lizards of three species acclimated to the three temperatures always differed from each other in CTMin, but not in Tsel, CTMax and VTR. Our results show that: temperature acclimation plays an important role in influencing thermal preference and tolerance in the three Eremias lizards, although the degrees to which acclimation temperature affects thermal preference and tolerance differ among species; thermal preference rather than tolerance of the three Eremias lizards corresponds with their latitudinal distributions

We isolated and characterizated 12 polymorphic microsatellite loci in the rapid racerunner Eremias velox (Squamata: Lacertidae). The loci were screened in 37 E. velox individuals. The number of alleles ranged from 6 to 16. The observed heterozygosity ranged from 0.432 to 0.919, and the expected heterozygosity ranged from 0.685 to 0.902. These microsatellite markers should prove useful for population genetic studies of E. velox and other Eremias species.

Triadimefon (TF) is a widely used chiral fungicide with one chiral centre and two enantiomers (TF1 and TF2). However, little is reported about the ecological toxicity of reptiles on an enantioselective level. TF is a potential endocrine disruptor that may interfere with sex steroid hormones, such as testosterone (T) and 17beta-estradiol (E2). In our study, the lizards Mongolia Racerunner (Eremias argus) were orally exposed to TF and its enantiomers for 21 days. Plasma sex steroid hormones and steroidogenic-related genes, including 17-beta-hydroxysteroid (hsd17β), cytochrome P450 enzymes (cyp19 and cyp17), and steroid hormone receptors (erα and Ar) were evaluated. After exposure, the plasma testosterone level in the 100 mg/kgbw group was elevated, while the oestradiol level was reduced. This phenomenon may be caused by the transformation of cyp19, which may inhibit the conversion of testosterone to oestradiol and affect sexual behaviour. In addition, the two enantiomers have different effects on hormone levels, which testified to the previously reported biotoxic dissimilarity between TF1 and TF2 in organisms. Furthermore, the cyp19 mRNA level in liver and gonad of the TF2 and TF group (100 mg/kgbw) were significantly down-regulated, while the cyp17 and hsd17β mRNA levels were up-regulated. The expression of erα and Ar mRNA levels were up-regulated in males but not in females, which may indicate that TF has sex differences on these two genes. As seen from the above results, TF and its enantiomers may have endocrine-disrupting effects on lizards (E. argus) by acting sensitively on sex steroid hormones and steroidogenic-related genes.

The Sox family of genes shares a high sequence similarity with the HMG box region of the human Y chromosomal gene, SRY. We used highly degenerate primers to clone and sequence seven Eremias breuchleyi Sox genes (EbSox2, EbSox3, EbSox4, EbSox11, EbSox12, EbSox14 and EbSox21). A database search for the cloned sequences revealed the following percentage identity with the homologous human SOX genes: EbSox2 = 96%, EbSox3 = 88%, EbSox4 = 94%, EbSox11 = 99%, EbSox12 = 96%, EbSox14 = 98%, EbSox21 = 97%. Cluster analysis indicates that they seem to belong to group B and group C of Sox gene family, respectively.

Electrocardiograms (ECG) of Eremias multiocellata were studied at 5-35 ℃ in body temperature.Electrocardiogram wave intervals (R-R,P-R,QRS,T-P,and R-T) shortened while heart rate increased with the increasing of body temperature.The average heart rate was 14.6/min at 5 ℃,whereas it was 201/min at 35 ℃.The duration of wave intervals of ECG and the heart rate were related significantly to the body temperature (P<0.001).Among the components of a cardiac cycle the cardiac rest period (TP intervals) and the atria-ventricular conduction time (PR interval) were affected mostly by body temperature.In the other hand the ventricular depolarization and repolarization (QRS and R-T intervals) were relatively less affected by the body temperature.The increasing of heart rate with body temperature was mainly caused by the shortening of ECG wave intervals,and the T-P interval (the cardiac rest period) was shortened more noticeably than other intervals.

采用甘肃省民勤县荒漠半荒漠环境中的卵胎生蜥蜴密点麻蜥(Eremias mutiocellata)为材料，研究其心电活动随体温变化的规律以及对环境温度的适应特点。共记录密点麻蜥125只，每只蜥蜴记录5、10、15、20、25、30、35 ℃7个温度等级，每个等级15-20只；少数蜥蜴记录的温度范围扩展到40、42、44、45和46℃。环境温度采用由电接点温度计和继电器控制的电冰箱和恒温箱来控制。体温测量采用SY-2型数字式温度计，测定时插入泄殖腔2 cm。心电描记采用LMS2B型二道生理记录仪。电极为不锈钢针形电极。实验前将蜥蜴放入待测温度环境中适应2 h。被测蜥蜴背位固定于木板上，不麻醉，将记录电极的正极插入左前肢皮下，负极插入右前肢皮下，地线插入后肢皮下，插入深度均为5 mm。电极固定后待蜥蜴的体温达到预定崐温度5 min后再开始心电记录。在实验记录纸上测量各波的电压值及各间期的时间，其中R-T间期即S-T段，表示从QRS波结束到T波结束的时间，T-P间期表示从T波结束到P波开始时的时间，P-R间期表示从P波开始到QRS波开始的时间，以t测验检验相关系数的显著性。体温为5-35 ℃时的心电图中P波和T波是正向的，且幅度很低，R波幅度高于P波和T波。P波电压值为0.027-0.0525 mV，多在5-25 ℃时出现，高体温(25 ℃以上)时大多数蜥蜴心电图上P波和T波重叠，不易分辨。Q波很小，大多不易辨认，S波在15 ℃以上时均可出现，且为负向波。体温由5 ℃上升至35 ℃时，心率由14.6次/min增加为201次/min。P-R、R-T和T-P间期的值都随之缩短。各间期值在各温度等级之间的差异都极显著(P<0.001)。在相同体温条件下，密点麻蜥的心率范围较一些作者报道的其他蜥蜴的心率都快，且差别很大。心率和体重之间有R＝153 Wt[0.207]的关系(Licht，1965)，密点麻蜥的体重小则心率快，但是密点麻蜥(E.Multiocellata)和荒漠沙蜥(Phrynocephalus przewalskii)的体重相似，心率却有差异，除种属差异外，也与生态环境的差异有关。 QRS/RR和RT/RR的值与体温呈正相关，而TP/RR和PR/RR的值与体温呈负相关。说明在体温升高时心动周期中各间期缩短的程度不同，即心脏的静息期(TP)和房室传导时间(PR)相对缩短，而心室开始去极化至复极化结束的时间(QRS和RT)相对延长。这一特征说明了密点麻蜥的心率随体温升高而加快的原因是静息期缩短和房室传导速度加快，而静息期缩短是最重要的因素。

The paper deals with the relationship between the body temperatures of Phrynocephalus przewalskii (Sthauch) and Eremias multiocellata (Guenther) and the environmental temperatures,their selections of environmental temperatures and their resistance against low and high temperatures.The body temperatures of przewalskii and Multiocellata were negatively interrelated to environmental temperatures (P<0.001).Under the same temperatures.The body temperatures of przewalskii were 3 ℃ higher than that of multiocellata.The environmental temperatures selected by the former were 38-40 ℃,whereas the latter required only 35-37 ℃.The hot and dead temperatures of przewalskii were higher than those of multiocellata.The threshhold of the hot and dead temperatures in przewalskii varied from 44 ℃ to 48 ℃ and its highest dead temperature (TL) was up to 48℃,and that in multiocellata was 42-46 ℃ and its highest hot temperature (TL) was 46 ℃.The ability that two species can resist against low temperatures was equal.The cold and dead temperatures varied from 0 ℃ to -3 ℃.The cold and dead temperatures (TL) of przewalskii were -2.3 ℃,but those of multiocellata were -2.5 ℃.These significant differences between the two species are concerned with the characteristics of each,habitats and sizes of the bodies.

How ectotherms exploit thermal resources has important implications for their habitat utilization and thermal vulnerability to climate warming. To address this issue, we investigated thermal relations of three sympatric lizard species (Eremias argus, Eremias multiocellata, and Phrynocephalus przewalskii) in the desert steppe of Inner Mongolia, China. We determined the thermoregulatory behavior, body temperature (Tb), operative temperature (Te), selected body temperature (Tsel), and critical thermal maximum (CTmax) of adult lizards. Based on these physiological parameters, we quantified the accuracy and effectiveness of thermoregulation as well as thermal-safety margin for these species. The three species were accurate and effective thermoregulators. The P. przewalskii preferred open habitats, and had a higher Tb than the two Eremias lizards, which preferred shade habitats and shuttled more frequently between the shade and sun. This indicated that the three sympatric lizards have different thermoregulatory behavior and thermal physiology, which might facilitate their coexistence in the desert steppe ecosystem. In addition, the P. przewalskii had higher Tsel and CTmax, and a wider thermal-safety margin than the two Eremias lizards, suggesting that the two Eremias lizards would be more vulnerable to climate warming than P. przewalskii.

The rapid racerunner, Eremias velox, is a widely distributed lizard from the northern Caucasus across entire Central Asia eastward to China. It is increasingly common to accept E. velox as a species complex in its entire range. To date, published morphological and molecular systematic hypotheses of this complex are only partially congruent, and its taxonomic status and evolutionary history are still far from clear. The mitochondrial cytochrome b gene and 12S rRNA sequences were used to evaluate the taxonomy of this complex, with particular attention to the phylogenetic placement of populations in northwestern China. Examination of the phylogenetic analyses recovers seven distinct, biogeographically discrete, and well-supported clades, revealing genetically identifiable populations corresponding to some previously morphology-defined subspecies. Chinese E. v. roborowskii appears to have split from other Central Asian rapid racerunner lizards well before differentiation occurred among the latter taxa. Specifically, we corroborate that there are two subspecies occurring in China, i.e., E. v. velox and £. v. roborowskii. We recommend a novel subspecific status for the phenotypically and genetically distinct populations in southern Aral Sea region of Uzbekistan previously assigned to E. v. velox. Finally, each of the three independently evolving lineages from Iranian Plateau should be recognized as three species new to science under the general lineage concept.

Late Cenozoic stepwise aridification has transformed Central Asia into an arid environment, and the Pleistocene climatic oscillations exerted further ecological impact. Therefore, both aridification and glaciation would have considerably influenced the evolution of many midlatitude species in arid Central Asia (ACA). However, strong biotic evidence supporting this role is still lacking. Here, we test this perspective using a phylogeographic study of Eremias velox, which is an arid-adapted lizard, across ACA using sequences from mitochondrial cytochrome b and 12S rRNA genes. Phylogenetic analyses of the concatenated data, including 595 specimens from 107 localities, revealed ten geographically correlated lineages that diverged by 1.1–15.4% for the cytochrome b gene and 1.0–10.3% for the 12S rRNA gene, which were estimated to have coalesced ∼6.23 million years ago. Ancestral area estimations suggested that E. velox originated from the Iranian Plateau and then dispersed into Central Asia. The intensification of aridification across Central Asia during the Late Pliocene may have facilitated the rapid radiation of this arid-adapted lizard throughout this vast territory. Subsequently, the geological events (e.g., uplift of the Kopet-Dagh, Tianshan and Greater Caucasus Mountains) and glacial oscillations during the Pleistocene triggered the progressive diversification of E. velox. The most recent common ancestor of the Caucasus-Central Asia clade was dated to approximately 2.05 Ma. Specifically, the diversification between the Caucasus clade (VI, VII) and the Central Asia clade (VIII, IX, X), and within the Central Asia clade may have been established and partially maintained by repeated transgressions of the Caspian Sea during the Pleistocene and Holocene. In contrast to demographic and/or range contractions in response to climatic changes during the Last Glacial Maximum (LGM) of the populations (Clades VI and X) from the Caucasus-Central Asia clade, mitochondrial evidence and ecological niche modeling support the signature of demographic and range expansions during the LGM for the Clade V populations (E. v. roborowskii, being endemic to the Turpan Depression). The effect of Pleistocene climatic changes on the historical demography of this arid-adapted species may be lineagespecific, depending predominantly on animal physiology and geography. Finally, we discuss the taxonomic implications, such as the appearance of the Turkmenistan populations as a distinct species, and E. v. roborowskii deserving a full species status.

Food composition in stomaches of 209 adults and 43 juveniles of Eremiqs multiocellata in Minqin area of Gansu Province is analyzed. The results show that Eremias multiocellata is a kind of omnivorous animal which mainly feeds on beetles and Nitraria fruits. After its dormancy, this animal begins to strongly ingest, its ingesting rate being more than 83%.It has an obvious seasonal variation of feeding habit, i.e. only animals are ingested inspring, half of animal and plant in summer, and third of plant in autumn.

In the present study, relationships among all Chinese species of lacertids in the genus Eremias, E. velox, E. grammica, E. vermiculata, E. przewalskii, E. multiocellata, E. arguta, E. brenchleyi, and E. argus, were assessed using 574 aligned base positions of 16S rRNA mitochondrial DNA sequences from 103 individuals collected from 28 populations. Three kinds of phylogenetic tree (MP, ME, and NJ) were reconstructed and were found to be concordant. All eight species well form a monophyletic group. The resulting genetic distance between E. przewalskii and E. multiocellata is surprisingly low, only 0.008. The result could be due to introgression of the mtDNA molecule. All Eastern-Asia lacertids except E. vermiculata grouped together and formed a monophyletic clade. E. vermiculata are closely related to E. arguta, a Central-Asia species. E. brenchleyi and E. argus formed a monophyletic clade as the sister group of E. multiocellata. The Central-Asia species (E. arguta, E. grammica and E. velox) originated from Central-Asia and Eastern-Asia species (the rest) from China. The phylogenetic relationships among E. grammica, E. velox, E. arguta-vermiculata, E. argus-brenchleyi, and E. multiocellata-przewalskii are unclear in the study, which needs more comprehensive taxonomic sampling from Western Asia and Europe, and additional genetic evidence to resolve it.

In order to get the information about the population structure of lizards,107 lizards are trapped from the outskirts of Lanzhou in Gansu province.There are 52 E.argus and 55 P.frontalis respectively.The population density of E.argus is 129/hm2 and P.frontalis is 100/hm2.Every population is divided into two classes(the submature class and the mature class).For E.argus the average of SVL is 34.2 mm of the submature class and that of the mature class is 54.5 mm.For P.frontalis the average of SVL is 35.4 of the submature class,and that for the mature class is 57.9 mm.The sex ratio(♀:♂) of the population is 1∶1.07 for E.argus and 1∶0.94 for P.frontalis,so they are close to 1∶1.The results show that the two populations can live in one and the same area.Eremias argus wakes earlier than Phrynocephalus frontalis.The body temperature of lizards is influenced by the ambient temperature of the environment and their physiology can be maintained by their behaviors.

Some data are presented on the ecology of two lizard species: Eremias velox and E. arguta inhabiting the so-called Ciscaucasian area of the USSR. Both species prefer sandy areas, but E. arguata being more eurytopic, is more tolerant to the anthropogenic disturbing effects in the Kalmykian region. Activity diagrams of both species have two maxima during the day. Beetles seem to be the dominant items in the diet of both species.

We collected adult Eremias argus (Lacertidae) from a population in Yangquan (Shanxi, northern China) to study thermal dependence of food assimilation and sprint speed. Selected body temperature (Tsel) measured on a laboratory thermal gradient was 36.0 °C; critical thermal minimum (CTMin) and critical thermal maximum (CTMax) averaged 1.0 °C and 44.9 °C, respectively. Differences in Tsel, CTMin and CTMax were not found between-sex. Within the range of body temperatures considered, food passage time, daily food intake, daily production of feces and urates, apparent digestive coefficient (ADC) and assimilation efficiency (AE) were all affected by body temperature. Food passage time decreased with increase in body temperature within the range from 26 °C to 34 °C, and then increased at higher body temperatures. Lizards at 30, 32, 34 and 36 °C ate more food and produced more feces and urates than did those at 28 °C and 38 °C. Although ADC and AE were both higher at 34 °C and 36 °C than at other lower or higher temperatures, no clear patterns associated with temperature could be discerned for these two variables. Sprint speed increased with increase in body temperature within the range from 18 °C to 36 °C, and then decreased at 38 °C. The body temperatures maximizing sprint speed was around 36 °C, which was much close to the mean value of body temperatures selected by lizards on the thermal gradient. This result adds evidence that the range of optimal body temperatures for sprint speed is tightly coupled with Tsel in lizards [Acta Zoologica Sinica 52(2):256–262, 2006].

Temperature variability is predicted to increase in the coming century due to climate change. However, the biological impact of increased temperature variability on animals remains largely unexplored. Here, we experimentally exposed gravid viviparous lizards (Eremias multiocellata) to two thermal environments [constant daily maximum (CDM) versus variable daily maximum (VDM) treatment with the same average temperature] to address maternal and offspring responses to increased variability in ambient temperature. Females from the VDM treatment delayed parturition, but produced similar litter sizes and litter masses as did CDM females. Offspring from the VDM treatment selected higher body temperatures, had higher metabolic rates and higher growth rates, and grew to a similar size as those from the CDM treatment despite having a shorter growth period prior to hibernation. Therefore, phenotypic plasticity may be critical for lizards to respond effectively to climate change, and its role in responding to increasingly variable temperatures warrants further attention.

The vulnerability of species to climate warming varies along latitudinal and elevational clines, but how sympatric species vary in vulnerability to climate warming remains largely unknown. We experimentally simulated nest temperatures of two sympatric lizards with divergent microhabitat preferences (Phrynocephalus przewalskii and Eremias argus), under climate warming senarios, to determine the response of embryos to increased mean temperatures and heat waves. Our study demonstrated that simulated climate warming reduced hatching success and hatchling size and growth in E. argus (that prefers closed microhabitats), but had less effect in P. przewalskii (that occupies open microhabitats). The reduced growth rate of E. argus hatchlings was associated with a decrease in metabolic rate, which was more evident in hatchling E. argus than in P. przewalskii. Our results suggest lizards that prefer closed microhabitats may be more vulnerable to climate warming than those that prefer open microhabitats; further studies are needed to test this hypothesis. More generally, the divergent responses of sympatric species to climate warming highlights the importance of distinguishing the thermal sensitivity of behavior and physiology for each species of a community, in order to make predictions about the impacts of climate warming at regional scales.

The diverse habitats of central Uzbekistan support a rich herpetofaunal community, but distributions and relative abundances of the species comprising this community remain poorly known. Here, we present an annotated species inventory of this under-explored area, with detailed notes on distributions and population statuses. Fieldwork was concentrated in southern Navoi and western Samarkand provinces, although some records were also made in the far north of Navoi province, near the city of Uchkuduk. Data were collected between March and May/June in 2011, 2012, and 2013, with herpetofaunal records being made opportunistically throughout this period. Survey effort was concentrated in semi-desert steppe area located to the south of the city of Navoi and an expanse of unnamed steppe located to the north of Navoi. Further records were made in a range of other habitat types, notably wetlands, sand dune fields, and low rocky mountains. Total fieldwork equated to approximately 8,680 person-hours of opportunistic survey effort. In total, we detected two amphibian and 26 reptile species in our study area, including one species classified as Globally Vulnerable by the IUCN. We present distributional data supporting the first record of regional range extensions of five species from within our study area. Our results represent the most detailed data concerning reptile and amphibian diversity and distributions produced from Uzbekistan in recent years. We conclude by recommending that further, systemized survey work needs to be conducted within the area to supplement our findings with more robust estimates of species abundances supported by more detailed information on specieshabitat relationships.

Die Albumine von 41 Arten der Familie Lacertidae, die einen maßgeblichen Anteil der Gattungen sowie
von infragenerischen Gruppen der Sammelgattung Lacerta s.l. repräsentieren, wurden mittels der MC`F-
Technik untersucht. Die Daten gestatten eine zeitliche Abschätzung der wesentlichsten Radiationsereignisse
und deren Korrelation mit paläogeographischen Gegebenheiten. Unsere Resultate stehen zum Teil in bemer-
kenswertem Widerspruch zu Ergebnissen von ARNOLD (1989a), die auf der Analyse vor allem
morphologischer Merkmale beruhen. Im wesentlichen ergaben sich folgende phylogenetische Beziehungen:
1. Die Gattungen Gallona und Psammodromus sind bereits seit dem Oligozän von den übrigen Taxa
isoliert. Wir taxieren diese beiden Hauptäste als Unterfamilien Gallotiinae und Lacertinae.
2. Lacerta s.str. und Lacerta Subgenus Zootoca stehen gemeinsam den restlichen Lacertinae als
3. Eine Besiedlung Afrikas im unteren Miozän führte zu einer Auftrennung in zwei Linien mit
hauptsächlich eurasischen beziehungsweise afrikanischen Vertetern.

Einheit, denn ein Teil der Gattungen ist eng mit europäischen Formen verwandt.

zur raum-zeitlichen Erklärung der Phylogenie der Lacertidae wird präsentiert.

The family Lacertidae encompasses more than 250 species distributed in the Palearctis, Ethiopis and Orientalis. Lacertids have been
subjected in the past to several morphological and molecular studies to establish their phylogeny. However, the problems of convergent
adaptation in morphology and of excessively variable molecular markers have hampered the establishment of well supported deeper phylogenetic
relationships. Particularly the adaptations to xeric environments have often been used to establish a scenario for the origin and
radiation of major lineages within lacertids. Here we present a molecular phylogenetic study based on two nuclear marker genes and
representatives of 37 lacertid genera and distinct species groups (as in the case of the collective genus Lacerta). Roughly 1600 bp of
the nuclear rag1 and c-mos genes were sequenced and analyzed. While the results provide good support to the hitherto suggested main
subfamilies of Gallotiinae (Gallotia and Psammodromus), Eremiainae and Lacertinae [Harris, D.J., Arnold, E.N., Thomas, R.H., 1998.
Relationships of lacertid lizards (Reptilia: Lacertidae) estimated from mitochondrial DNA sequences and morphology. Proc. R. Soc.
Lond. B 265, 1939–1948], they also suggest unexpected relationships. In particular, the oriental genus Takydromus, previously considered
the sister-group to the three subfamilies, is nested within Lacertinae. Moreover, the genera within the Eremiainae are further divided into
two groups, roughly corresponding to their respective geographical distributions in the Ethiopian and the Saharo-Eurasian ranges. The
results support an independent origin of adaptations to xeric conditions in different subfamilies. The relationships within the subfamily
Lacertinae could not be resolved with the markers used. The species groups of the collective genus Lacerta show a bush-like topology in
the inferred Bayesian tree, suggesting rapid radiation. The composition of the subfamilies Eremiainae and Lacertinae as well as their
phylogeography are discussed.

The paper describes the history of biogeographic views on the herpetofauna of both Dagestan and the Caucasus as a whole. The species are grouped into eight zoogeographic groups on the basis of our de- tailed chorological analysis. Mesophilous and xerophilous refuges of the Dagestan herpetofauna are de- scribed. Our herpeto-geographical subdivision of the territory is given. The territory of Dagestan is lo- cated in the Palaearctic subkingdom of Holarctic kingdom and divided between two areas, namely, the Turanian and Mediterranean ones. The boundary between the regions is the junction of the northern foot- hills and plains of the Eastern Caucasus. A possible reconstruction of the regional herpetofauna genesis is considered.

Aim Body size is instrumental in influencing animal physiology, morphology, ecology and evolution, as well as extinction risk. I examine several hypotheses regarding the influence of body size on lizard evolution and extinction risk, assessing whether body size influences, or is influenced by, species richness, herbivory, island dwelling and extinction risk.
Methods I used literature data and measurements of museum and live specimens to estimate lizard body size distributions.
Results I obtained body size data for 99% of the world`s lizard species. The body size–frequency distribution is highly modal and right skewed and similar distributions characterize most lizard families and lizard assemblages across biogeographical realms. There is a strong negative correlation between mean body size within families and species richness. Herbivorous lizards are larger than omnivorous and carnivorous ones, and aquatic lizards are larger than non-aquatic species. Diurnal activity is associated with small body size. Insular lizards tend towards both extremes of the size spectrum. Extinction risk increases with body size of species for which risk has been assessed.
Main conclusions Small size seems to promote fast diversification of disparate body plans. The absence of mammalian predators allows insular lizards to attain larger body sizes by means of release from predation and allows them to evolve into the top predator niche. Island living also promotes a high frequency of herbivory, which is also associated with large size. Aquatic and nocturnal lizards probably evolve large size because of thermal constraints. The association between large size and high extinction risk, however, probably reflects a bias in the species in which risk has been studied.

Aim Temperature influences most components of animal ecology and life history
– but what kind of temperature? Physiologists usually examine the influence of
body temperatures, while biogeographers and macroecologists tend to focus on
environmental temperatures. We aim to examine the relationship between these
two measures, to determine the factors that affect lizard body temperatures and to
test the effect of both temperature measures on lizard life history.
Methods We used a large (861 species) global dataset of lizard body temperatures,
and the mean annual temperatures across their geographic ranges to examine
the relationships between body and mean annual temperatures.We then examined
factors influencing body temperatures, and tested for the influence of both on
ecological and life-history traits while accounting for the influence of shared
Results Body temperatures and mean annual temperatures are uncorrelated.
However, accounting for activity time (nocturnal species have low body temperatures),
use of space (fossorial and semi-aquatic species are ‘colder’), insularity
(mainland species are ‘hotter’) and phylogeny, the two temperatures are positively
correlated. High body temperatures are only associated with larger hatchlings and
increased rates of biomass production. Annual temperatures are positively correlated
with clutch frequency and annual longevity, and negatively correlated with
clutch size, age at first reproduction and longevity.
Main conclusions Lizards with low body temperatures do not seem to have
‘slower’ life-history attributes than species with high body temperatures. The longer
seasons prevalent in warm regions, and physiological processes that operate while
lizards are inactive (but warm enough), make environmental temperatures better
predictors of lizard life-history variation than body temperatures. This surprisingly
greater effect of environmental temperatures on lizard life histories hints that global
warming may have a profound influence on lizard ecology and evolution.

Aim We provide a new quantitative analysis of lizard reproductive ecology. Comparative
studies of lizard reproduction to date have usually considered life-history
components separately. Instead, we examine the rate of production (productivity
hereafter) calculated as the total mass of offspring produced in a year. We test
whether productivity is influenced by proxies of adult mortality rates such as
insularity and fossorial habits, by measures of temperature such as environmental
and body temperatures, mode of reproduction and activity times, and by environmental
productivity and diet. We further examine whether low productivity is
linked to high extinction risk.
Methods We assembled a database containing 551 lizard species, their phylogenetic
relationships and multiple life history and ecological variables from the literature.
We use phylogenetically informed statistical models to estimate the factors
related to lizard productivity.
Results Some, but not all, predictions of metabolic and life-history theories are
supported. When analysed separately, clutch size, relative clutch mass and brood
frequency are poorly correlated with body mass, but their product – productivity –
is well correlated with mass. The allometry of productivity scales similarly to
metabolic rate, suggesting that a constant fraction of assimilated energy is allocated
to production irrespective of body size. Island species were less productive than
continental species.Mass-specific productivity was positively correlated with environmental
temperature, but not with body temperature. Viviparous lizards were
less productive than egg-laying species. Diet and primary productivity were not
associated with productivity in any model. Other effects, including lower productivity
of fossorial, nocturnal and active foraging species were confounded with
phylogeny. Productivity was not lower in species at risk of extinction.
Main conclusions Our analyses show the value of focusing on the rate of annual
biomass production (productivity), and generally supported associations between
productivity and environmental temperature, factors that affect mortality and the
number of broods a lizard can produce in a year, but not with measures of body
temperature, environmental productivity or diet.

Aim: Small geographic ranges make species especially prone to extinction from an- thropogenic disturbances or natural stochastic events. We assemble and analyse a comprehensive dataset of all the world’s lizard species and identify the species with the smallest ranges—those known only from their type localities. We compare them to wide-ranging species to infer whether specific geographic regions or biological traits predispose species to have small ranges.
Methods: We extensively surveyed museum collections, the primary literature and our own field records to identify all the species of lizards with a maximum linear geo- graphic extent of <10 km. We compared their biogeography, key biological traits and threat status to those of all other lizards.
Results: One in seven lizards (927 of the 6,568 currently recognized species) are known only from their type localities. These include 213 species known only from a single specimen. Compared to more wide-ranging taxa, they mostly inhabit relatively inaccessible regions at lower, mostly tropical, latitudes. Surprisingly, we found that burrowing lifestyle is a relatively unimportant driver of small range size. Geckos are especially prone to having tiny ranges, and skinks dominate lists of such species not seen for over 50 years, as well as of species known only from their holotype. Two- thirds of these species have no IUCN assessments, and at least 20 are extinct.
Main conclusions: Fourteen per cent of lizard diversity is restricted to a single location, often in inaccessible regions. These species are elusive, usually poorly known and little studied. Many face severe extinction risk, but current knowledge is inadequate to properly assess this for all of them. We recommend that such species become the focus of taxonomic, ecological and survey efforts.

The distribution of steppe-runners in the surveyed region depends on the presence of sandy substrates. Eremias arguta inhabits sandy steppes with low vegetation. The northern distribution limit of steppe- runners in the south of European Russia lies about 50 – 53°N. The morphological character of steppe- runners there shows both cline and discrete variations. The cline variations are independent in the Don and Volga basins, which supports the idea of past distribution ways of the species. A gradient of discrete characters also occurs in the Don and Volga interfluves. There are some populations in the Taman penin- sula and Daghestan which are characterized by a unique combination of characters. Some individuals from the right-side Volga-river populations are characterized by a morphology intermediate between E. a. arguta and E. a. deserti, because of the intergradation zone adjacency. Substrate «loose sand» and «im- movable sand» forms in the Middle Don-river populations were discovered.

В результате проведенного исследования удалось установить, что распространение вида на территории России определяется наличием песчаных грунтов. Разноцветная ящурка населяет песчаные степи ранних стадий зарастания. Северная граница распространения вида на исследуемой территории проходит примерно на 50 - 53° с.ш. Разноцветная ящурка на территории Европейской части России имеет сложную популяционную структуру. Количественные и качественные признаки характеризуются клинальной и дискретной изменчивостью. Клинальная изменчивость выражена в бассейнах Дона и Волги независимо - в прошлом продвижение вида на север происходило по пескам речных долин. Перепад частот дискретных признаков также наблюдается в Волго-Донском междуречье. Имеются изолированные популяции вида, характеризующиеся особым сочетанием признаков на Таманском полуострове и на Червленых Бурунах. У особей некоторых популяций разноцветной ящурки с правобережья Волги имеются признаки промежуточного характера между западным и номинативным подвидами - это обусловлено близостью зоны интерградации этих подвидов. На песках Среднего Дона у разноцветной ящурки есть эдафические формы, соответствующие условиям обитания на сыпучих или закрепленных песках.

The etymology of the reptiles, especially the lizards of Iran has not been completely presented in
other published works. Iran is a very active geographic area for any animals, and more especially for lizards,
due to its wide range deserts and ecology. We have attempted to ascertain, as much as possible, the construction
of the Latin binomials of all Iranian lizard species. We believe that a review of these names is instructive, not
only in codifying many aspects of the biology of the lizards, but in presenting a historical overview of collectors
and taxonomic work in Iran and Middle East region. We have listed all recorded lizards of Iran according to
the order of the scientific names in the book of Anderson, The Lizards of Iran. All lizard species and types have
been grouped under their proper Families, and then they have been alphabetically ordered based on their
scientific binominal nomenclature. We also examined numerous published works in addition to those included
in the original papers presenting each binomial.

We describe a new species of Eremias lacertid from the Alborz Mountain range in northern Iran (Tehran Province). Eremias
papenfussi n. sp. is part of the Eremias subgenus (or morphotype) by virtue of lacking lateral fringes on the fourth
toe and color pattern. It can be further differentiated from previously described species assigned to this morphotype by the absence of distinctly keeled upper caudal scales, gular scales that do not extend to the second inframaxiallary scales, color pattern, and scale counts. Eremias papenfussi is found on rocky mountain slopes of the Alborz where it is presumed to have a much broader distribution than demonstrated by the available specimens. Of the 15 species of Eremias known from Iran, E. papenfussi is the fifth species known to inhabit rocky mountain slopes along with E. strauchi, E. lalezharica, E. montanus and E. novo.

From the viewpoint of evolution, the classes of amphibians and reptiles could be considered as relicts, and because they are poikilothermic animals, it’s very difficult for these species to live under the dry and cold climatic conditions in Mongolia. Even species diversity is poor, Mongolian herpetological composition is unique, highly adopted to the country’s harsh climate and originated a long time ago. In Mongolia, 6 species of amphibians belong to four genera, four families and two orders and the recorded 21 species of reptiles belong to 13 genera in 6 families of 2 suborders.

Four species from the E. multiocellata-complex occur in Kyrgyzstan and southeastern Kazakhstan. e taxonomic state of the populations from Kazakhstan is ambiguous. e results of comparative morpho- logical analysis (habitus, color pattern on the dorsal side of the body, metric and meristic characters) in the E.stummeri from two localities in Kyrgyzstan (including type locality) and south-eastern Kazakh- stan are presented. Signi cant di erences were revealed in Sq., G. and L. /L. cd features. As a result, the racerunners from the southeastern Kazakhstan are morphologically identi ed as E. stummeri. Our ob- servations and the analysis of the museum collections con rm independent speci c states of three allo- patric species of E. multiocellata-complex in Kyrgyzstan and Kazakh Tien Shan.

Steppe-runner Eremias arguta (Pallas 1773) is one of the most widespread species of the Asian racerunners (genus Eremias) inhabiting steppes, semi-deserts and deserts of Eastern Europe, Middle and Central Asia. Several subspecies were traditionally recognized, however, their morphological variability is so high that the delimitation and establishing of formal taxonomical status of some populations was always problematic. The metric and meristic morphological characters of E. arguta from 12 populations of Kazakhstan, Uzbekistan, northwestern China and southwestern Mongolia were analyzed using different multivariate statistic methods and preliminary results of molecular analysis of mtDNA cytochrome b gene. The studied populations are clustered in five groups. Based on both morphological and molecular characters, the southernmost populations from Uzbekistan and Chimkent region (Kazakhstan) form a clearly separated group E. a. uzbekistanica, quite different from all other subspecies. The populations from the Ili River valley (southeastern Kazakhstan and northwestern China) were formerly considered as transitional ones between E. a. arguta — E. a. uzbekistanica or E. a. potarcini, but in fact they represent a separate form. The easternmost samples assigned as `E. a. potanini` are deeply nested within E. a. arguta cluster and seem to be a local form with clinal variation of morphological characters.

Разноцветная ящурка один из наиболее широко распространенных видов азиатских ящурок, населяющий степи, полупустыни и пустыни Восточной Европы, Средней и Центральной Азии. Традиционно внутри вида распознавали несколько подвидов, однако изменчивость признаков внешней морфологии так высока, что определение подвидов и придание таксономического статуса некоторым популяциям, особенно в восточной части ареала, всегда было проблематичным.

Here we present the main results of our 2008 field research held in the south-western Mongolia by a herpetological team of the Russian – Mongolian biological expedition. 13 reptile species belonging to five families and eight genera have been recorded. Phrynocephalus versicolor was the most widespread and abundant lizard species. Eremias przewalskii and E. multiocellata were also common in semi-fixed sands subjected to considerable over-grazing (Dundgov’, Umnegov’). Several new localities for Ph.versicolor hispida and E. m. multiocellata and E. m. reticulata are reported. Cyrtopodion elongatum was found in the Nogondov (=Nogon-Dovon) valley located in 300 km northwards from the previously known occurrence of this species. This valley inhabited by Teratoscincus przewalskii, Eremias vermiculata, and Eryx tataricus can be considered as the most western part of the Trans-Altai Gobi Desert adjacent to the Mongolian Dzungaria. The actual status of the C. elongatum populations seems to be out of concern because, according to our night observations, the population density exceeds 20 ind per 500 m². The taxonomical status of Ph. v. hispida and E. m. reticulata is discussed, and the specific status of racerunners collected in the area of their sympatry in the Hovd aimag was confirmed. Some coloration features of living adults and juveniles individuals of the lizards (especially, Eremias and Phrynocephalus species) are reported.

We provide an integrative analysis of the diversity of the E. multiocellata—E. przewalskii species complex in Central and Middle Asia using morphological and molecular (COI DNA-barcoding) data. We report preliminary data on mtDNA variation within this group and clarify the taxonomic status and distribution of the members of the species complex. We also provide a description of a new Eremias species from Eastern Kazakhstan and western Mongolia, where it occurs in sympatry with E. multiocellata sensu stricto, from which it can be clearly differentiated using both morphological and molecular characters. The new species, described as Eremias dzungarica sp. nov., is assigned to the subgenus Pareremias on the basis of the following features: subocular not reaching mouth edge; one frontonasal; two supraoculars; the row of small granular scales between supraoculars and frontal with frontoparietals absent; distance between the femoral pore rows being wide; femoral pore rows not reaching knee-joint; coloration pattern with light colored ocelli with black edging. The new species can be distinguished from its congeners on the basis of the following morphological attributes: a mediumsized lacertid lizard, maximum snout-vent length (SVL) = 64.5 mm, tail being ca. 1.5 times longer than body length (SVL), hindlimbs relatively long (hindlimb length to SVL ratio 0.46); subocular scale not reaching mouth edge, in touch with 6–8 supralabials; males with bright coloration consisting of 2–3 dorsolateral rows of light-colored ocelli with thick black edging; the ventral row of ocelli in life is greenish to bluish; dorsal pattern consisting of black irregular blotches along the middorsal line. We also report on the high genetic and morphological diversity of E. multiocellata in Mongolia and China, synonymize E. m. bannikowi with the nominative form E. m. multiocellata, discuss variation within E. przewalskii, synonymize E. p. tuvensis with the nominative form E. przewalskii, provide new data on E. cf. reticulata and E. m. tsaganbogdensis, confirm validity and clarify distribution ranges of E. stummeri, E. szczerbaki and E. yarkandensis and discuss further progress on taxonomic studies of the E. multiocellata—E. przewalskii species complex.

The Mongolian racerunner (Eremias argus) is a small lacertid lizard species, and its distribution range encompasses the Korean Peninsula, Mongolia, China and Russia. Eremias argus is widespread, but populations on the Korean Peninsula are small and declining, provoking concerns that genetic diversity is being lost. This species is currently listed under the Protection of Wild Fauna and Flora Act in South Korea. In this study, nine novel microsatellites for E. argus were developed with a biotin-enrichment method and used to understand its population genetic structure and delineate conservation units on the Korean Peninsula. Overall, low intrapopulation genetic diversity was observed (mean number of alleles per locus = 2.463; mean H E = 0.398) from 10 populations investigated (n = 110). Two populations (among five with n≥ 10) showed an excess of heterozygosity expected under HWE relative to that expected at mutation-drift equilibrium, indicating severe reduction in population sizes. With only a few exceptions, the overall genetic differentiation among populations was substantial with the high levels of pairwise-F ST (0.006-0.746) and -R ST (0.034-0.940) values. The results of Bayesian STRUCTURE analysis showed that E. argus populations on the Korean Peninsula were most likely partitioned into three genetic clusters. Taken all together, such low levels of gene flow and strong genetic structuring have critical implications for the conservation of this endangered species and its management.

Lacertinae is one of the three lacertid lizard subfamilies with a geographical distribution confined to the
Palaearctic. Several past attempts to reconstruct its phylogeny resulted in unresolved bush-like topologies.
We address the question of whether the lack of resolution is due to insufficient data or whether this
lack reflects a rapid succession of speciation events. We analyzed four partial and one complete gene
sequences from mitochondrial and nuclear genomes, totalling roughly 3600 bp. We included 29 species
representing all 19 genera suggested in recent revision of Lacertinae [Arnold, E.N., Arribas, O., Carranza, S.,
2007. Systematics of the palaearctic and oriental lizard tribe Lacertini (Squamata: Lacertidae: Lacertinae),
with descriptions of eight new genera. Zootaxa 1430, 1–86]. The resulting phylogeny, first, corroborates
monophyly at the genus level for the suggested genera, as well as the finding that Atlantolacerta andreanskyi,
until recently part of Lacertinae, belongs to the subfamily Eremiadinae. Second, we find that
increasing the sequence length and combining multiple nuclear and mitochondrial sequences did not
resolve the polytomy, suggesting that the inferred topology indicates a multiple cladogenesis within a
short geological period, rather than a methodical artefact. Divergence time estimates, based on previous
estimates of several node ages, range from 13.9 to 14.9 million years for the radiation event, however
with very broad confidence interval. To associate the radiation with a narrower geological time we consider
palaeogeographic and palaeoclimatic data, assuming that the Lacertinae probably evolved in Central
Europe andWAsia after the collision of Africa and Eurasia. We suggest that this radiation may date to the
late Langhian (ca. 14–13.5 million years) when geological events caused abrupt changes in regional
water–land distribution and climate, offering a window of distinct conditions.

Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and short-wavelength colour patches are located on the ventral and lateral surfaces of many lacertid lizards. As the combination of long- and short-wavelength-based colours generates local chromatic contrast, we hypothesized that selection may favour the co-occurrence of lateral and ventral contrasting patches, resulting in complex colour patterns that maximize the overall conspicuousness of the signal. To test this hypothesis we performed a comparative phylogenetic study using a categorical colour classification based on spectral data and descriptive information on lacertid coloration collected from the literature. Our results demonstrate that conspicuous ventral (long wavelength-based) and lateral (short wavelength-based) colour patches co-occur throughout the lacertid phylogeny more often than expected by chance, especially in the subfamily Lacertini. These results suggest that selection promotes the evolution of the complex pattern rather than the acquisition of a single conspicuous colour patch, possibly due to the increased conspicuousness caused by the combination of colours with contrasting spectral properties.

Steppe racerunner, Eremias (Eremias) arguta, is one of the most widespread species of the Asian racerunners (genus Er-emias). Several subspecies were traditionally recognized however, morphological variability is so high that delimitation of these subspecies was always problematic. Here we present a phylogenetic hypothesis for this species based on cyto-chrome b sequences (55 samples from 35 populations, 900 bp partial sequences), infer it biogeography and the revise its subspecific structure. Six major phylogenetic lineages were revealed. The southernmost populations (E. a. uzbekistanica) from Uzbekistan form a clade together with the Issyk-Kul Lake subspecies (E. a. darevskii) based on both molecular and morphological evidence. Within more northern populations, there is a split between populations from Northern Caucasus, Europe and Western Kazakhstan (E. a. deserti) and Central and Eastern Kazakhstan populations (E. a. arguta). Transcau-casian (E. a. transcaucasica) steppe racerunners are grouped with Middle Asian populations. Finally, the easternmost samples, assigned to “E. a. potanini” are nested within the E. a. arguta clade. Populations from the Ili River Valley form a separate lineage sister to the clade joining all other E. arguta lineages and might represent a yet undescribed taxon. Spe-cies distribution in relation to historical biogeography of Middle Asia is discussed.

We used the Mongolian racerunner Eremias argus as a model animal to evaluate the effects of constant versus fluctuating incubation temperatures on hatching success and hatchling phenotypes. Eggs were incubated under four constant [24, 27, 30 and 33 (±0.3) °C] and one fluctuating temperature regimes. Hatching success did not differ among treatments, and incubation temperature did not affect the sexual phenotype of hatchlings. Incubation length decreased exponentially as incubation temperature increased, and eggs incubated at fluctuating temperatures took a longer time to complete development than did those incubated at constant temperatures with the same mean. Of the hatchling phenotypes examined, body dry mass, carcass dry mass, residual yolk dry mass and locomotor performance of hatchlings were more likely to be affected by incubation temperature. Overall, locomotor performance was best in the low temperature treatments (24 °C and 27 °C) and worst in the high temperature treatment (33 °C), with the moderate temperature treatments (30 °C and fluctuating temperatures) in between. Our data show that: (1) daily exposure of eggs to extreme temperatures that are potentially lethal to embryos for brief periods does not have detectable adverse effects on hatching success and morphological phenotypes in E. argus; and (2) thermal fluctuations exert no positive effects on locomotor performance of hatchlings but influence incubation length differently than constant temperatures with the same mean [Acta Zoologica Sinica 52(6):1049 – 1057, 2006].

The resting metabolic rates (RMR) of two species of lizards Eremias argus and Phrynocephalus frontalis were measured in April and May 1990. The results showed a positive correlation between RMR and temperature and an inversely exponential relationship of RMR with body weight. Laboratory acclimation indicated that the rates of bodyweight losting in both species of lizard were more sensitive to temperature in the range of 10～15℃ and 20～25℃. The circadian ryhthm of RMR of both species were also noted. The difference of RMR between two species was not significant.

Eremias montanus belonging to the family Lacertidae and is an endemic lizard of Iran. Endemic species because only certain geographical areas there are many values are for academic studies. In this study to find these regions to make a lot of Hamedan province were studied, but observed only in Alvand Mountain in 18 km Hamedan province. The research was performed from early April until late November in 2009; while this species spend hibernation and samples were collected by line transect method. In total 13 samples were collected the 10 specimens were mature and 3 specimens were immature and morphological, ecological and ethological studies were conducted on them. In this study, for the first time this species was detected in Hamedan province, whereas reported only in previous studies of Siah dareh Village in Kermanshah province.

The rapid fringe-toed lizard, Eremias velox, is widely distributed in the Iranian plateau and
Central Asia. Several local morphotypes have so far been reported from different parts of
its range, representing this taxon as a species complex. In an attempt to reveal
phylogenetic relationships among various populations of this complex group, 37
specimens from 13 geographically distant localities in Iran and central Asia, covering
most parts of its range, were sampled. Using Inter Simple Sequence Repeat amplification
(ISSR-PCR) as a molecular marker, whole the nuclear genome of all specimens was
screened. Phylogenetic analysis of the prepared data set successfully recovered seven
major clades within the E. velox complex. Relationships among the major clades were
highly resolved with remarkable statistical supports and well correspond to the
geographic distribution of the populations. The reconstructed phylogeny implies that the
clade as a whole has been originated in the Iranian plateau and expanded into central Asia
before uplifting the Kopet-Dagh Mountains. It has then undergone a rapid cladogenesis
in the latter area and produced several morphotypes. Within the Iranian clades two main
groups could be defined, the foothill and highland dwellers and the open plane and desert
dweller populations. The phylogenetic tree together with the estimated amounts of
genetic distances among the independent lineages, provide good grounds for a
fundamental revision of the taxonomic status of the Eremias velox complex.

Iran is located in an area that is bordered by several mountains and contains herpetofaunal
constituents from adjacent countries such as Pakistan, Iraq, Afghanistan, and Turkey. We
surveyed several border provinces of Iran to more completely understand the Iranian herpetofauna.
During one survey in the northwestern part of Iran we found a species of the genus Eremias that can
be added to Iran’s herpetofauna. Previously, the distribution of Eremias suphani was limited to the Van Lake in Turkey (type locality). We compared Iranian samples with E. suphani from Turkey using a molecular marker (Cytochrome b) and confirmed that this species is also present in Iran. The new record of this species is located on the road from Firoragh to Chaldoran in the west of the province of Azarbaijan, Iran.

Strauch`s Racerunner, Eremias strauchi, is represented by two subspecies, Eremias strauchi strauchi Kessler, 1878 and Eremias strauchi kopetdaghica Szczerbak, 1972, occurring in opposite margins on the northern Iranian Plateau. We sequenced 3926 base pairs of nuclear and mitochondrial DNA from 16 samples of Eremias strauchi, Eremias lalezharica and Eremias velox collected from northeastern, northwestern and southern Iran. Phylogenetic analyses revealed that Eremias lalezharica is sister to Eremias strauchi kopetdaghica and caused the currently recognised species Eremias strauchi to be paraphyletic. According to the estimated genetic distances in the mitochondrial fragments among the lineages, E. s. strauchi diverged from E. s. kopetdaghica and E. lalezharica with a mean genetic distance of 14.0% and 13.9% respectively. Our data indicate enough molecular divergence between the two currently recognised subspecies of E. strauchi and justify upgrading them to full species level as Eremias strauchi (for the north-western clade) and Eremias kopetdaghica (for the north-eastern clade).

The Persian racerunner Eremias persica Blanford, 1875 is confined to the Iranian plateau, and forms one of the most widespread but rarely studied species of the family Lacertidae. With many local populations inhabiting a variety of habitats, and exhibiting considerable morphological, genetic, and ecological variations, it represents a species complex. We analysed sequences of mitochondrial cytochrome b and 12S ribosomal RNA (rRNA) genes derived from 13 geographically distant populations belonging to the E. persica complex. Using our knowledge of palaeogeographical events, a molecular clock was calibrated to assess the major events in fragmentation, radiation, and intraspecific variation. The sequence data strongly support a basal separation of the highland populations of western Iran from those of the open steppes and deserts, occurring in the east. The subsequent radiation, fragmentation, and evolution of these major assemblages have led to several discernable geographical lineages across the wide area of the Iranian plateau. The results indicate a middle-Miocene origin for the clade as a whole. The first split, isolating the western and eastern clades, appears to have occurred 11–10 Mya. Further fragmentations and divergence within the major clades began about 8 Mya, with an evolutionary rate of 1.6% sequence divergence per million years among the lineages in the genes studied (combined data set). Molecular and morphological data strongly support a taxonomic revision of this species complex. At least four of the discovered clades should be raised to species, and two to subspecies, rank.

A new species of the lacertid genus Eremias Fitzinger, 1834 is described from northwest of Isfahan province, Central Iran. Two mitochondrial genes (cyt b and 12S DNA) were sequenced and analyzed as reliable molecular markers for the separation of this newly discovered species from closely related species within the genus Eremias: E. velox, E. persica, E. papenfussi, E. lalezharica, E. montana, E. strauchi, E. kopetdaghica and E. suphani. Genetic distances (K2-p) between any of these species with the newly described species are relatively high (27.5–32.8% for cyt b and 5.2–10.4% for 12S DNA). Phylogenetic analyses (MP, ML and BI) generated trees with very similar topologies. According to molecular and morphological data, Eremias isfahanica sp. nov. belongs to the subgenus Aspidorhinus, and is closely related to E. papenfussi. Because several new Eremias species have recently been described from the Iranian Plateau, we additionally provide an updated identification key.

Eremias velox (Gattung Eremias) aus Zentralasien gehört zu den weit verbreiteten Eidechsen Eurasiens. Nucleotidsequenzen mitochondrialer DNA (Cytochrom b und 12 S rDNA) von 13 geographisch unterschiedlichen Standorten aus dem Iran und Zentralasien wurden genauer analysiert. Die phylogenetische Auswertung fand 5 genetische Linien innerhalb des E. velox– Komplexes, die sich durch große genetische Distanzen unterscheiden und auf lange Zeiten der Isolation hinweisen. Innerhalb der Gesamtphylogenie liegen die iranischen Kladen basal. Dies deutet darauf hin, dass der E. velox Komplex im mittleren Miozän auf dem iranischen Plateau entstand. Aufgrund von Kalkulationen über eine molekulare Uhr wird angenommen, dass die nordiranischen Linien von 10–11 Millionen Jahren entstanden, während sich die zentralasiatischen Taxa vor 6 Ma abzweigten. Dies wurde vermutlich durch die Entstehung der Kopet-Dagh-Berge am Nordrand des iranischen Plateaus ausgelöst. Die Baumtopologie und die genetischen Distanzen bieten eine gute Grundlage dafür, den taxonomischen Status der hier gefundenen Hauptlinien des E. velox – Komplexes neu zu bewerten.

A new species of the lacertid genus and subgenus Eremias is described based on material collected by the senior author from 150 km northeast of Shiraz, Fars province, south-central Iran at about 1800 m elevation. It differs from all other Iranian species of the typical subgenus (E. persica, E strauchi, E velox and E. lalezharica) in that it has a very distinctive and unique color pattern, unmistakable in this character the wide dorsolateral stripe is uniformly black without light spots and there is no ocelli on the upper surface of limbs; the third pair of submaxillary shields are separated by 4 granular scales; and the tympanic shield is rudimentary and almost absent. The new species is sympatric with Eremias persica and apparently restricted in distribution to the steppes and open plains in the northern regions of Fars province south-central Iran.

A new and distinctive form belonging to the genus and subgenus Eremias Fitzinger, 1834 is reported from the highlands of Alvand Mountains, Hamedan Province, western Iran at about 2700 m elevation. It is easily distinguished from all the other species of the typical subgenus (E. velox, E. persica, E. strauchi, E. nigrolateralis E. lalezharica E. afghanistanica, E. regeli, E. suphani, and E. nikolskit) by having a variable number of postmentals (4-5 pairs); smaller size, and a distinctive color pattern. Furthermore, it can be distinguished by having a combination of characters against any of the species in the typical subgenus. Further work, using both morphological arid molecular techniques, is now being carried out on this new form in order to determine its exact taxonomic and phylogenetic status. Systematics of the genus Eremias is shortly discussed.

Distributions of amphibian and reptile faunas were separately delimited on a 1:20 000 000 vegetation map of Northern Eurasia divided into 245 10-degree-longitudinal segments of native subzone within the USSR borders as of 1990. All reptile and amphibian species recorded in every segment were listed, and the Jaccard indices were calculated, and the similarity matrix was studied with cluster analysis. Hierarchic classifications were made: the amphibian one consisting of 3 faunistic regions, divided into 4 subregions, 7 biologic provinces, and 23 districts. The reptile classification includes 4 faunistic regions, 7 subregions, 18 provinces, and 14 districts. The reptile classification has 1.5 times more provincial and district subdivisions than amphibian one. Environmental factors correlating with faunistic nonuniformity were revealed. Our amphibian and reptile schemes are 1.9 and 3.5 times more informative than those proposed earlier and account for 75 and 91% of variance in the faunal similarity coefficient of specific areas, respectively (multiple correlation coefficients 0.87 and 0.95). Environmental factors can explain 84 and 93% of faunistic nonuniformity (correlation coefficients 0.95 and 0.96).

Der Nordosten Irans, ein faszinierendes Gebiet, einerseits durch die immense Ausdehnung arider (Hoch-) Ebenen und Hügelländer, andererseits durch die überraschende landschaftliche Vielfalt unmittelbar südlich des Kaspischen Meeres. So kontrastieren die beeindruckend dichten Hyrcanischen Wälder und das über 5000 m hohe Elburs-Gebirge die endlosen, staubtrockenen Weiten im Landesinneren. Dementsprechend groß ist auch die dortige Artenvielfalt: Knapp 60 Reptilien- und Amphibienarten konnten im Zuge der 14-tägigen Exkursion auf der 4000 km langen Rundtour beobachtet werden.

While the stability of sex chromosomes is widely accepted in viviparous mammals and birds, ectothermic vertebrates are still largely viewed as having frequent turnovers in sex determining systems. Frequent changes in sex determining systems in ectotherms could be problematic for field ecological studies as well as for breeding programs, as molecular sexing across a phylogenetically widespread spectrum of ectothermic vertebrates would not be possible. However, we recently documented that sex determining systems in three important reptile lineages (caenophidian snakes, iguanas, and lacertid lizards) are in fact highly conserved. 2.We applied a new molecular procedure to identify sex within each of these three lineages (encompassing altogether around 4,000 species, i.e. nearly 50% of the recent species of reptiles). This technique uses quantitative PCR (qPCR) to compare copy numbers of genes specific for their respective Z (in caenophidian snakes and lacertids) and X (in iguanas) chromosomes between male and female genomes. The DNA samples required can be collected relatively non-invasively. Unlike molecular sexing based on repetitive elements, this technique can be easily applied to previously unstudied species of these lineages, as the number of copies of protein coding genes linked to the differentiated sex chromosomes is evolutionary highly conserved in each. 3.We suggest that qPCR-based molecular sexing using the comparison of gene copy number is a practical choice for non-model species of caenophidian snakes, iguanas and lacertids. Morever, it should also soon be available for other reptile lineages with differentiated sex chromosomes.

Telomeres are nucleoprotein complexes protecting the physical ends of linear eukaryotic chromosomes and therefore helping to ensure their stability and integrity. Additionally, telomeric sequences can be localized in non-terminal regions of chromosomes, forming so-called interstitial telomeric sequences (ITSs). ITSs are traditionally considered to be relics of chromosomal rearrangements and thus very informative in the reconstruction of the evolutionary history of karyotype formation. We examined the distribution of the telomeric motifs (TTAGGG)n using fluorescence in situ hybridization (FISH) in 30 species, representing 17 families of squamate reptiles, and compared them with the collected data from another 38 species from literature. Out of the 68 squamate species analyzed, 35 possess ITSs in pericentromeric regions, centromeric regions and/or within chromosome arms. We conclude that the occurrence of ITSs is rather common in squamates, despite their generally conserved karyotypes, suggesting frequent and independent cryptic chromosomal rearrangements in this vertebrate group.

Sex chromosomes are believed to be stable in endotherms, but young and evolutionary unstable in most ectothermic vertebrates. Within lacertids, the widely radiated lizard group, sex chromosomes have been reported to vary in morphology and heterochroma- tinization, which may suggest turnovers during the evolution of the group. We compared the partial gene content of the Z-specific part of sex chromosomes across major lineages of lacertids and discovered a strong evolutionary stability of sex chromosomes. We can conclude that the common ancestor of lacertids, living around 70million years ago (Mya), already had the same highly differentiated sex chromosomes. Molecular data demonstrating an evolutionary conservation of sex chro- mosomes have also been documented for iguanas and caenophidian snakes. It seems that differences in the evolutionary conservation of sex chromosomes in vertebrates do not reflect the distinction between endotherms and ectotherms, but rather between amniotes and anamniotes, or generally, the differences in the life history of particular lineages.

Squamata is the most diversified reptilian order that has been traditionally classified into three suborders - Lacertilia, Serpentes and Amphisbaenia in which Lacertilia have about 16-19 families. But the phylogenetic relationships among major groups of Lacertilia remain controversial. In this paper, the complete mitochondrial DNA sequence of Eremias brenchleyi was determined by using long-and-accurate PCR (LA-PCR). The mtDNA sequence is 19 542 bp, making it the longest mitochondrial genome in squamates species reported so far. It shows the typical vertebrate arrangement of genes. The control region of E. brenchleyi was characterized by two conspicuous 65 bp and 56 bp tandem repeats at its 5′ and 3′ terminus respectively. In order to study the higher level relationships of squamates, the phylogenetic study including all currently available squamates mitochondrial sequences was carried out. We obtained a relationship of 16 families of lizards (Lacertidae, Scincidae, Iguanidae, Chameleonidae, Agamidae, Trogonophidae, Bipedidae, Shinisauridae, Helodermatidae, Amphisbaenidae, Gekkonidae, Varanidae, Anguidae, Xantusiidae, Rhineuridae, Cordylidae) and 8 families of Serpentes. The internal relationships within this group yielded high bootstrap support and were more congruent with morphological analyses.

Climate condition is an important key affecting species presence, especially for reptiles. Precipitation and temperature are especially important environmental factors to consider. In the present study, I collected as many presence records as possible for seven lizard species from the Sistan region and analyzed them in relation to environmental variables using the maximum entropy algorithm. According to the analysis, temperature seasonality affected the distributions of three species (Eremias fasciata, Ophiomorus tridactylus, Teratoscincus bedriagai) and precipitation affected the presence of four species (Ablepharus pannonicus, Bunopus tuberculatus, Cyrtopodion scabrum, Trapelus agilis). The most important variable affecting E. fasciata and O.tridactylus (23% of contribution) is isothermality. For T. bedriagai, temperature seasonality was more important (32% contribution). Annual precipitation was the most highly contributed variable for A. pannonicus. Precipitation of the wettest month has a high contribution for the other species, representing 49, 48, and 54% for B. tuberculatus, C. scabrum and T. agilis, respectively.

In this paper, the evolution and ecology of directional asymmetry (DA) during the developmental trajectory (DT) is compared with that of its product, morphological DA (MDA). DT and MDA are calculated for two bilateral morphological scale characters of lizards, the number of subdigital lamellae beneath the fourth toe in 10 agamid and 28 lacertid taxa, and the number of rows of ventral scales in 12 lacertid taxa. MDA, the subtraction between left and right sides (classical measure of DA), is functional in adult animals. Results confirm the hypodiesis that, in DT, the regression parameters a (constant) and b (regression slope) of counts on the right side with those on the left describe a developmental process. No phylogenetic or environmental effects were observed on a and b, but analyses considering both a and b together show non-random phyletic patterns. Independent analyses deduced the same ancestral DT in Agamidae and Lacertidae. In Lacertidae, distance between pairs of taxa in a + b (standardized values) correlates positively with die phylogenetic distance between taxa. Phyletic trends in MDA are indirect, and due to the link of MDA with a + b. The MDA of species is more dissimilar in sympatry than in allopatry. The phyletic trends suggest evolution of DT, while die association of MDA witii sympatry suggests that ecological pressures shape MDA in adult animals. Evolution of DT is independent from tiiat of its product, MDA–adaptive determinism defines the result of, but not the mechanistic process of, development. Deterministic environmental processes define MDA, and deterministic evolutionary processes define the interactive result of a and b, but not each separately. According to circumstances, different DTs produce similar or different MDA, and a particular DT can produce different MDAs.

Chinese lizards (Eremias argus) were exposed to separated R-(-)-triadimefon, S-(+)-triadimefon and racemic triadimefon to evaluate enantioselective accumulation of triadimefon. After single oral administration of R-(-)-triadimefon, S-(+)-triadimefon and racemic triadimefon, the time-concentration curves in different tissues were found to be different. Triadimefon enantiomers crossed the blood-brain barrier and brain is a main target organ. The residues of triadimefon enantiomers in fat were highest after 24 h indicating that fat was the main tissue of accumulation. In racemic triadimefon exposure group, the enantiomer fractions of R-(-)-triadimefon in different tissues showed that the differences between R-(-)-triadimefon and S-(+)-triadimefon were significant in absorption and metabolism, but the differences became smaller in exclusion and accumulation. From the results of mathematical models, S-(+)-triadimefon was absorbed and eliminated faster than R-(-)-triadimefon, and R-(-)-triadimefon was easily distributed in the tissues and more easily converted into its metabolites. Furthermore, among the four enantiomers of triadimenol, SR-(-)-triadimenol produced by S-(+)-triadimefon may have the highest fungicidal activity and the strongest biological toxicity, RR-(+)-triadimenol produced by R-(-)-triadimefon was most likely to bioaccumulate in lizard. Identifying toxicological effects and dose-response relationship of SR-(-)-triadimenol and RR-(+)-triadimenol will help fully assess the risk of TF enantiomers use in the future. The results enrich and supplement the knowledge of the environmental fate of triadimefon enantiomers.

We present a comprehensive summary of the distribution of the lizards of Iran accompanied by an annotated checklist. The updated maps of distribution of all 146 species of 41 genera of 11 families are based on all available bibliographic records, catalogues of museum collections and our own field observations. The final dataset used for the distribution maps contains 8525 georeferenced records and cover 41% of the country when plotted on a grid of 0.25° × 0.25° resolution. The dataset is publicly accessible through GBIF portal (http://www.gbif.org/dataset/7db4f705-61ae-4c6e-9de2-06674e7d46b2). Following the latest biogeographic division of the country, ~53% of the species (76 species) inhabit the Iranian Province, ~41% (60 species) the Western Asian mountain transition zone, ~9% (13 species) the Turanian Province, and ~18% (27 species) the Arabian Province. In addition, ~2% (3 species) reach Iran from the Indo-Malay biogeographic region and ~2% (3 species) are believed to have been introduced to Iran by humans. Endemic species (46) represent ~32% of the known species diversity. The most species-rich family of lizards in Iran is Lacertidae with 47 species, followed by Gekkonidae (41), Agamidae (18), Scincidae (15), Phyllodactylidae (10), Sphaerodactylidae (4), Eublepharidae and Uromastycidae (3), Anguidae and Varanidae (2), and Trogonophidae with one representative.

To determine the size of an Eremias argus population at Baramarae beach in Taeanhaean National Park, we used Peterson’s index and Schnabel’s index. In addition, we provided physical characteristics of male and female E. argus. During our study period, we captured total 152 lizards and among them, 23 individuals were recaptured. The 152 lizards consisted of 54 adult males, 79 adult females, and 19 subadults, respectively. Physical characteristics such as snout-vent length (SVL), tail length (TL), and body mass (BM) were not different between males and females. We recaptured total 23 individuals which consisted of six males and seventeen females. More females (21.5%) tended to be recaptured than males (11.1%), with total average recapture rate of 15.1%. The size of the E. argus population at Baramarae beach was estimated as 438 individuals (Min.-Max.: 226-650) by the Peterson’s method and 470 individuals (Min.-Max.: 334-796) by the Schnabel’s method.

Life history traits may vary within and among species. Rarely, however, are both variations examined concurrently to identify the life history adaptation. We found that female body size, offspring number and size, and incubation period showed convergent evolution in two lacertid lizards (Takydromus wolteri and Eremias argus) that occur sympatrically in high-latitude and low-latitude localities. Females from the high-latitude population were larger and produced larger clutches than those from the low-latitude population. In both species, the incubation period was shorter for the high-latitude population than for the low-latitude population. However, the physiological mechanism underlying the shorter incubation period differed between the species. These results suggest that: (1) sympatric lizards may adopt similar reproductive strategies in response to their common environments, and (2) embryonic development of the two species follows different pathways for adaptation to low temperatures. This study highlights the importance of understanding the adaptive evolution of life history in response to environmental changes at the embryonic life stages.

The results of our chromosome studies on Eremias arguta from the Samara and Saratov regions are presented. The diploid set of E. arguta from the Volga populations surveyed has been found to include 38 chromosomes: 2n = 38, NF = 38. The female and male karyotype structures are 2n = 35M + 3m and 2n = 36M + 2m, respectively. The karyotype of E. arguta from the Saratov and Samara regions is shown to be similar to the earlier described chromosome sets of the subspecies E. a. deserti. At the same time, the Saratov E. a. deserti differ from E. arguta from the Samara region by the number of pairs of NO-carrying chromosomes, which in the Saratov E. arguta are found on the 2nd, 4th, and 7th chromosome pairs, and in the Samara ones – on the 1st, 2nd, 4th, and 9th pairs.

The modern distribution of Eremias arguta is considered. The species is shown to be represented by stable populations on a vast territory of the Volga region (Saratov and Samara regions) at present, its habitat there is mosaic and the abundance is comparable with that at the central part of the whole habitat. In view of the gradual average annual temperature elevation trend within the territory under study and some stabilization of moisture indices, a decrease in abundance and a shift south of the northern habitat boundary should be expected. Since the peripheral settlements of E. arguta in the Volga region are of separate nature, the species is recommended to enter the Red Books of the Saratov and Samara regions.

Альбинос степной черепахи (Agrionemys horsfleldi (Gray, 1844)) был найден автором 17 апреля 1975 г. в предгорьях хребта Ренин-Тау, в 20 км к юго-востоку от г. Душанбе на высоте около 1200 м над уровнем моря. До этого автор с 1957 г. участвовал в полевых работах по изучению мелких наземных позвоночных, в том числе и черепах, в районах, где численность этого вида весьма велика, но среди многих тысяч просмотренных особей ни одного альбиноса не встретилось. Не было альбиносов и среди 40000 черепах, отловленных в Юго-Западном Таджикистане заготовителями для отправки их за границу. В публикациях, посвященых среднеазиатской черепахе, и в работах об альбиносах у позвоночных животных (Hensley, 1959; Arnoldt, 1980; Bechtel, 1995;) найти сообщений об альбиносах этого вида нам не удалось. По-видимому, это первая находка альбиноса среднеазиатской черепахи.

The modern distribution of Eremias velox (Pallas, 1771) is considered. E. velox is shown to be represented now by rather stable populations witrhin a vast territory of the Lower-Volga region and adjacent territories within Republic Kalmykia and the Astrakhan region, its habitat being of a mosaic character. In view of isolation of the peripheral settlements of E. velox in the territory under survey, the species should be entered in the regional Red Books.

A viviparous lizard, Eremias multiocellata, was used to investigate the possible sexual and ontogeneticeffects on selected body temperature, thermal tolerance range and the thermal dependence of locomotorperformance. We show that adults are sexually dimorphic and males have larger bodies and heads thanfemales. Adults selected higher body temperatures (34.5 vs. 32.4◦C) and could tolerate a broader rangeof body temperatures (8.1–46.8 vs. 9.1–43.1◦C) than juveniles. The sprint speed and maximum sprintdistance increased with temperature from 21◦C to 33◦C, but decreased at 36◦C and 39◦C in both juvenilesand adults. Adults ran faster and longer than juveniles at each tested temperature. Adult locomotor performance was not correlated with snout–vent length (SVL) or sex, and sprint speed was positivelycorrelated with hindlimb length. Juvenile locomotor performance was positively correlated with bothSVL and hindlimb length. The ontogenetic variation in selected body temperature, thermal toleranceand locomotor performance in E. multiocellata suggests that the effects of morphology on temperatureselection and locomotor performance vary at different ontogenetic stages.

Temperature-dependent sex determination (TSD) is well studied in many species of reptiles, but little is known on how geographic distribution and altitude affect the sex ratio. In the present study, we focused on a population of a viviparous lizard with TSD (Eremias multiocellata) that lives at high altitudes (≈2900 m) in Tianzhu, Gansu province, China. Gestation temperature had a notable effect on the offspring sex ratio, gestation period, and the mother`s body mass. The mothers produced female biased offspring at 25 °C but male biased offspring at 35 °C. All female lizards lost weight during pregnancy, and the least loss of the body mass was observed at 31 °C. The gestation period increased in a non-linear fashion as ambient temperature was reduced. Average litter size was elevated with an increase of gestation temperatures, reached a maximum at 31 °C, and then declined at 35 °C. Compared with a previous study on a Minqin population which lives at a lower altitude (≈1400 m) and warmer climate, the present study obtained a less skewed sex ratio of offspring in the Tianzhu population. Geographic variations also affected offspring morphology between the two populations; females collected from Tianzhu produced larger litters but with a smaller body weight of offspring. These differences may be caused by the adaptive response to the cool climatic and high-altitude environmental conditions.

By the PAAG electrophoretic spectra of Coomassi-stained 61-73 bands from 4 “tissues” (heart, skeletal muscle, kidney, liver proteins) for each of 17 specimens representing at least 3 or 4 species, (Eremias vermiculata Blanf., E. przewalskii Str., E. sp. and E. multiocellata Gunther) were compared.Most of the specimens were collected in Mongolia. Their tree, based on several measures of genetic distances, showed the order of the species listed above, with E. sp., the closest to the point of divergency, and situated between E. przewalskii and the specimen of E. multiocellata from several localities and biotypes. The genetic similarity of the biotypes of the last species is discussed in regard with other data on the body size and proportion, pholidosis, coloration.

This article gives a complete overview about the reptiles of western Turkmenistan and their zoogeographical relation. The data were obtained by several expeditions during the last years and completed by compilation of the specific herpetological literature about this area. Ten general landscape units are described along a profile from the Central Karakum desert throughout the Malyi Balkhan chains, the Kyurendag Corridor, the Western Kopetdagh to the state border of Iran. The mountain and plain reptile fauna is analyzed. After discussing the faunal element composition of various landscapes, the Western Kopetdagh was included into the South-West Asian province while the Turanian plain and the Malyi Balkhan were included into the Turanian province of the Palearctic.

The age structure of Eremias suphani was studied from a high-altitude (2180 m a.s.l.) locality in eastern Turkey. A total of 24 preserved (16 males, 7 females, and 1 juvenile) specimens were used in this study. According to the skeletochronological analysis, ages ranged from 6 to 9 years (mean: 7.38 ± 0.22 years) in males and from 6 to 10 years (mean: 7.86 ± 0.51 years) in females. Age at maturity was estimated to be 5–6 years for both males and females. The mean snout–vent length was calculated as 60.88 ± 2.61 mm in males and 58.85 ± 2.44 in females. The sexual dimorphism index was calculated as –0.03. The difference between the sexes for both age and size was not statistically significant.

The aim of this study was to determine if divergence in habitat use among lacertid lizards is paralleled by morphological differentiation. For 35 lacertid species, we measured body, head and limb dimensions. Habitat use was inferred from the literature: ground-dwelling on open terrain, ground-dwelling in vegetated areas, shrub-climbing, tree-climbing, saxicolous (i.e. rock-climbing). Traditional (i.e. non-phylogenetic) statistical analyses suggest morphological differences among species groups with different habitat use. Ground-dwelling species from open habitats tend to have longer femurs, tibiae and humeri (relative to body length) than other groups. Cursorial (i.e. level-running) species have relatively high heads and trunks compared to climbing species. These differences follow biomechanical predictions and it is tempting to consider tham as adaptations to habitat use. However, phylogenetic analyses of the data fail to establish a clear relationship between habitat use and morphology in the data set considered. There is a weak indication that the differences in head and trunk height have evolved as an adaptation to different habitat use, but the differences in relative limb dimensions among species groups with different habitat use vanish. Either adaptation of limb dimensions to habitat use has not occurred in lacertid lizards, or our methods are unable to demonstrate such an adaptation. We show that uncertainties in the topology of the phylogenetic tree used are unlikely to influence the outcome of our study. We also address the fact that habitat use is often similar in different branches of the phylogenetic tree, and the consequences this may have for the power of our statistical analyses.

Background: The present-day amphibian and reptile fauna of Western Siberia are the least diverse of the Palaearctic Realm, as a consequence of the unfavourable climatic conditions that predominate in this region. The origin and emergence of these herpetofaunal groups are poorly understood. Aside from the better-explored European Neogene localities yielding amphibian and reptile fossil remains, the Neogene herpetofauna of Western Asia is understudied. The few available data need critical reviews and new interpretations, taking into account the more recent records of the European herpetofauna. The comparison of this previous data with that of European fossil records would provide data on palaeobiogeographic affiliations of the region as well as on the origin and emergence of the present-day fauna of Western Siberia. An overview of the earliest occurrences of certain amphibian lineages is still needed. In addition, studies that address such knowledge gaps can be useful for molecular biologists in their calibration of molecular clocks. Methods and Results: In this study, we considered critically reviewed available data from amphibian and reptile fauna from over 40 Western Siberian, Russian and Northeastern Kazakhstan localities, ranging from the Middle Miocene to Early Pleistocene. Herein, we provided new interpretations that arose from our assessment of the previously published and new data. More than 50 amphibians and reptile taxa were identified belonging to families Hynobiidae, Cryptobranchidae, Salamandridae, Palaeobatrachidae, Bombinatoridae, Pelobatidae, Hylidae, Bufonidae, Ranidae, Gekkonidae, Lacertidae, and Emydidae. Palaeobiogeographic analyses were performed for these groups and palaeoprecipitation values were estimated for 12 localities, using the bioclimatic analysis of herpetofaunal assemblages. Conclusion: The Neogene assemblage ofWestern Siberia was found to be dominated by groups of European affinities, such as Palaeobatrachidae, Bombina, Hyla, Bufo bufo, and a small part of this assemblage included Eastern Palaearctic taxa (e.g. Salamandrella, Tylototriton, Bufotes viridis). For several taxa (e.g. Mioproteus, Hyla, Bombina, Rana temporaria), the Western Siberian occurrences represented their most eastern Eurasian records. The most diverse collection of fossil remains was found in the Middle Miocene. Less diversity has been registered towards the Early Pleistocene, potentially due to the progressive cooling of the climate in the Northern Hemisphere. The results of our study showed higher-amplitude changes of precipitation development in Western Siberia from the Early Miocene to the Pliocene, than previously assumed.

The composition and distribution of the vertebrate fauna of Afghanistan remain poorly documented and in recent decades little new data have become available due to a series of wars and the resulting unstable security conditions. As Afghanistan returns to some semblance of normalcy, baseline faunistic data will be particularly important for establishing national conservation priorities as well as for placing Afghan taxa into their broader phylogenetic and zoogeographic contexts. We here provide an updated checklist of the herpetofauna of Afghanistan based in part upon biodiversity archives of specimen records from several museum and private collec- tions as well as literature references and field research. The herpetofauna of Afghanistan consists of 118 species and subspecies belonging to 58 genera and 21 families. Seven species are endemic to the country, whereas 18 taxa have to be delet- ed from previous lists of the Afghan herpetofauna. Afghanistan’s primary zoogeo- graphic relationship to the Palearctic Region is reaffirmed but with secondary influ- ence from the Oriental Region. Immediately following the checklist, two sections provide information about species probably occurring in Afghanistan and previous- ly mentioned species that are now recognized as absent.

Eremias multiocellata is a viviparous lizard that is known to exhibit temperature-dependent sex determination (TSD). Conventional Giemsa staining under light microscope examination has iden-tified the karyotype of this species to be 2 n = 36 I + 2 m, with no detectable heteromorphic sex chromosomes. However, a highly differentiated female-specific chromosome, W, which is homo-morphic with the Z chromosome, is found in the present study by the high-resolution cytogenetic method of comparative genomic hybridization (CGH). The results show that E. multiocellata is a viviparous lizard with both TSD and ZW heterogametic sex chromosomes. Despite the fact that a different sex ratio of male offspring was found in two populations (separated by an altitude of 1400 m) in previous incubation experiments, we demonstrate, using genomic in situ hybridization (GISH), that there is no significant chromosomal loss or acquisition between the two populations. This suggests that temperature may play a more important role in lowland populations. These results most likely indicate that E. multiocellata is transitioning between the evolutionary processes of TSD and genotypic sex determination (GSD) systems, and also give clues to the effect of TSD versus GSD in this process.

The metabolic process of diflubenzuron in rat or fish has been well studied, but little is known about its elimination pathway in lizard. The current study predicted the metabolic route of diflubenzuron in lizard feces and compared the toxicity of diflubenzuron and 4-chloroaniline on lizard thyroid system. The amido bond cleavage was the major route for diflubenzuron elimination in lizard feces. 4-Chloroaniline as the most toxic diflubenzuron metabolite was also abundant in feces. According to liver slices, 4-chloroaniline exposure induced significant changes of nuclear shape, while diflubenzuron exposure caused significant hepatocytes clustering. On the basis of thyroid hormone and thyroid-related gene levels, triiodothyronine (T3) level in lizard liver was regulated by thyroid hormone receptors, while thyroxine (T4) concentration was modulated by dio2 and udp genes after diflubenzuron or 4-chloroaniline exposure. These results showed that both diflubenzuron and 4-chloroaniline could disrupt lizard thyroid system, which could provide evidence for lizard population decline.

Benalaxyl as a xylem-systemic fungicide is usually direct sprayed on the soil surface, which is potential harm to the animals lived in the soil. However, the stereoselectivity of benalaxyl in reptiles have rarely been studied. In this study, Chinese lizards (Eremias argus) were firstly used to evaluate the stereoselectivity in biodegradation and toxicity of racemate and individual enantiomers of benalaxyl. A method for determining residues of the two enantiomers of benalaxyl in lizard blood and liver by high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (HPLC-MS/MS) was developed. The degradation followed pseudo first-order kinetics and the degradation of the (S)-(+)-benalaxyl was faster than its antipode in blood and liver (Half-time t1/2 of (R)-(−)-benalaxyl and (S)-(+)-benalaxyl were 5.08 h and 3.75 h in blood, 6.21 h and 4.45 h in liver, separately). Moreover, antioxidant defenses consisting of activities of superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) and lipid peroxide malondialdehyde (MDA) were determined in 24 h acute exposure. Enantioselectivity of acute toxicity depended on the concentration and form of benalaxyl. In addition, cellular degeneration, decrease of cell number, clustering phenomena of cell nuclei and preliminary liver fibrosis were observed in pathological detection at the termination of 21-d subchronic exposure (20 mg/kg−bw of racemate and individual enantiomers of benalaxyl). The enantiomer fractions (EFs) in racemate and individual enantiomer groups were approached both in blood and liver caused by the chiral conversion. The chiral conversion from (R)-(−)-benalaxyl to (S)-(+)-benalaxyl and (S)-(+)-benalaxyl to (R)-(−)-benalaxyl were the primary cause for no remarkable differences in toxicity between the enantiomers of benalaxyl.

The Chinese lizards (Eremias argus) were used to evaluate the metabolism, distribution and effect of dinotefuran following oral exposed. The HPLC equipped with Q Exactive focus was used for metabolite identification and concentration analysis. After single oral administration, the time-concentration curves of dinotefuran and its metabolites were tissue-dependent. The liver and kidney were the major metabolic organs. Percutaneous and urinary excretions were the main ways for lizards to eliminate dinotefuran, and the urine output was the limiting factor. Nitro-reduction was an important process of the metabolism of dinotefuran that was dominated by aldehyde oxidase, and P450 enzymes were involved. The CYP3A4 and CYP2C19 played a crucial role in the other metabolic pathways of dinotefuran. The mRNA expressions of GST family were severely inhibited in liver, which showed dinotefuran might pose a risk of damaging the oxidative stress system in liver. Prolonged residuals of dinotefuran and its demethylation metabolite might enhance the risk of dinotefuran to brain. The results enrich and supplement the knowledge of the environmental fate of dinotefuran in reptiles.

Systematically evaluation of the metabolism, distribution and effect of imidacloprid in Chinese lizards (Eremias argus) were carried out following oral exposure. Imidacloprid-olefin-guanidine was prone to accumulate in the brain and caused potential neurotoxicity. Percutaneous and excretory excretions were the primary ways for the elimination of imidacloprid and its metabolites. Liver was the main site for hydroxy reduction and nitro-reduction metabolism of imidacloprid. The metabolism of imidacloprid was a complex process in which many metabolic enzymes participated. Aldehyde oxidase and CYP2C9 were the key enzymes in nitro-reduction process. CYP3A4 dominated the process of hydroxylation and desaturation. The increase in Glutathione S-transferase expression may be related to the removal of imidacloprid, but also related to the oxidative stress reaction that imidacloprid may cause in tissues, especially in the kidney. The findings enrich and supplement the knowledge of the environmental fate of imidacloprid in reptiles.

1. Whether maternal effects are adaptive or not has been a long-standing topic of discussion in evolutionary ecology. The effects of maternal diet on offspring have been addressed by several studies on diverse organisms, but results are typically conflicting or inconclusive. 2. In this study, we conducted food manipulation experiments with a factorial design (high and low maternal food conditions × high and low offspring food conditions) in a viviparous lacertid lizard (Eremias multiocellata) to test four competing hypotheses on the evolutionary significance of maternal effects: environmental matching hypothesis, low-food compensation hypothesis, low-food pathology hypothesis and no-compensation hypothesis. 3. We found that offspring under the maternal low-food treatment had higher growth and survival rates than those under the maternal high-food treatment, supporting the low-food compensation hypothesis rather than the environmental matching hypothesis, which has been widely accepted as an explanation for the adaptive significance of maternal effects. 4. Our study highlights the importance of testing multiple competing hypotheses that involve both adaptive and non-adaptive explanations when studying the evolutionary significance of phenotypic plasticity.

In this research, Chinese lizards (Eremias argus) were chosen as laboratory animal to evaluate the stereoselectivity in the processes of metabolism, distribution, and bioaccumulation of triadimefon. A validated chiral high-performance liquid chromatography coupled with triple quadruple mass spectrometry (HPLC–MS/MS) method was developed for determining enantiomers’ residues of parent compound triadimefon and its metabolite triadimenol in lizard blood and tissues. Pharmacokinetic results of single-does exposure suggested that S-(+)-triadimefon was metabolized easier than R-(−)-triadimefon, and RR-(+)-triadimenol was the main metabolic product of triadimefon. During the continuous exposure of two dose (40 mg/kgbw•d and 200 mg/kgbw•d), enantiomers of triadimefon and triadimenol were detected in all body compartments, with the highest triadimefon concentrations in brain. However, the triadimenol concentrations were not significantly different among the compartments. The concentrations of RS-(+)-triadimenol were negative correlated with concentrations of RR-(+)-triadimenol both in blood (r=−0.775, p=0.024) and liver (r=−0.834, p=0.02) in 200 mg/kgbw•d group, which indicates that chiral conversion between enantiomers of triadimenol might exist in the metabolic process of triadimefon. In all the processes, the enantiomer fractions (EFs) of R-(−)-triadimefon and RR-(+)-triadimenol were significantly different from their natural ratios, 0.5 and 0.1, respectively, which proved that metabolism, bioaccumulation, and distribution of triadimefon and triadimenol in lizards were enantioselective. These results help enrich and supplement the knowledge of the stereoselective behaviour of triadimefon and triadimenol in reptile.

Extreme high temperatures are occurring more frequently with ongoing anthropogenic climate warming, but the experimental tests of the effects of high temperatures on terrestrial vertebrates in natural conditions are rare. In this study, we investigated the effects of extreme high temperatures on female reproduction and offspring traits of multi-ocellated racerunners (Eremias multiocellata) kept in field enclosures in the desert steppe of Inner Mongolia. Our studies indicate that high temperatures significantly affect the gestation period and reproductive output of females and the offspring sex ratio, but have little impact on offspring body size and mass. More interestingly, we found that the effect of extreme high temperatures on female reproductive output was not consistent between two consecutive years that differed in precipitation. Low precipitation may aggravate the impact of climate warming on lizards and negatively affect the survival of lizards in the desert steppe. Our results provide evidence that temperature interacts with precipitation to determine the life history of lizards, and they suggest that a drier and hotter environment, such as the future climate in arid mid-latitude areas, will likely impose severe pressure on lizard populations, which are an important component of the food web in desert areas around the world.

The neurotoxicity of dinotefuran, thiamethoxam and imidacloprid against Chinese lizards (Eremias argus) were evaluated in acute oral exposure and 28d subchronic exposure. Dinotefuran was not easily metabolized and showed strong persistence in the lizard brain. Thiamethoxam and imidacloprid were rapidly absorbed and excreted in lizards, and were not easily enriched in the lizard brain. Dinotefuran and thiamethoxam could directly increase the concentrations of acetylcholine in the brain and blood by up-regulating the expression of the ach gene, which in turn enhanced the binding of acetylcholine and acetylcholinesterase receptors, eventually causing the release of dopamine. The effect of dinotefuran was more pronounced than thiamethoxam. Clothianidin was a major metabolite of thiamethoxam in the brain and aggravated the neurotoxic effects of thiamethoxam. Imidacloprid desnitro olefin was the only metabolite of imidacloprid that enriched in the brain. The protonation effect of imidacloprid desnitro olefin was stronger than that of the parent imidacloprid, which increased its binding ability to lizard acetylcholinesterase receptors. Competitive inhibition of imidacloprid desnitro olefin and acetylcholine led to the down-regulation of ach gene expression. Although neonicotinoids caused the opening of ligand-gated ion channel through the activation of acetylcholinesterase receptors, the body would alleviate these effects by the inhibition of voltage-dependent channel activity for compensatory mechanisms. This study provided a new perspective on the neotoxic effects of neonicotinoids.

The potential endocrine disruption of neonicotinoids poses a significant threat to the survival of small farmland lizards. We systematically evaluated the distribution, metabolism, and toxicity of three neonicotinoids (dinotefuran, thiamethoxam, and imidacloprid) in the Eremias argus during a 35-day oral administration exposure. Lizards could quickly transfer and store neonicotinoids into the scale and eliminated through molting. Dinotefuran was most prone to accumulation in lizard tissues, followed by thiamethoxam, and imidacloprid was generally present in the form of its terminal metabolite 6-chloropyridinyl acid. Exposure to dinotefuran resulted in hepatic oxidative stress damage, decreased plasma growth hormone concentration, and down-regulation of ghr, igf1 and igfbp2 gene expression. These indicated that dinotefuran might have potential growth inhibition toxicity to lizards. Although imidacloprid caused severe liver oxidative stress damage, the effect of imidacloprid on GH/IGF axis was not obvious. Compared to dinotefuran and imidacloprid, thiamethoxam had the least damage to liver and minimal impact on GH/IGF axis. This study verified the possible damage of neonicotinoids to lizard liver and the interference of GH/IGF axis for the first time.

Systematic evaluation of the metabolism, distribution, and effect of thiamethoxam in Mongolian racerunner (Eremias argus) was carried out after oral exposure. HPLC equipped with Q Exactive focus was used for identification and concentration analysis of thiamethoxam and its metabolites. Percutaneous and urine excretions were the primary ways for the elimination of thiamethoxam and its metabolites, and the limiting factor was urine output. Demethylated thiamethoxam and clothianidin were the main metabolites of thiamethoxam in lizards. CYP3A4, CYP3A7, and CYP2C9 played a crucial role in the metabolism process. Aldehyde oxidase only dominated the nitro-reduction process of demethylated thiamethoxam and clothianidin. Glutathione S-transferase might be related to the clearance process of thiamethoxam and its metabolites. The findings indicated that thiamethoxam might pose potential carcinogenic and hepatic injury risk to lizards. The results enrich and supplement the knowledge of the environmental fate of thiamethoxam in reptiles.

Background: Studies of lizards have shown that offspring size cannot be altered by manipulating clutch size in species with a high clutch frequency. This raises a question of whether clutch frequency has a key role in influencing the offspring size- number trade-off in lizards.
Methodology/Principal Findings: To test the hypothesis that females reproducing more frequently are less likely to tradeoff offspring size against offspring number, we applied the follicle ablation technique to female Eremias argus (Lacertidae) from Handan (HD) and Gonghe (GH), the two populations that differ in clutch frequency. Follicle ablation resulted in enlargement of egg size in GH females, but not in HD females. GH females switched from producing a larger number of smaller eggs in the first clutch to a smaller number of larger eggs in the second clutch; HD females showed a similar pattern of seasonal shifts in egg size, but kept clutch size constant between the first two clutches. Thus, the egg size- number trade-off was evident in GH females, but not in HD females.
Conclusions/Significance: As HD females (mean = 3.1 clutches per year) reproduce more frequently than do GH females (mean = 1.6 clutches per year), our data therefore validate the hypothesis tested. Our data also provide an inference that maximization of maternal fitness could be achieved in females by diverting a large enough, rather than a higher-than-usual, fraction of the available energy to individual offspring in a given reproductive episode.

Prothioconazole (PTC) is a widely used triazolinthione fungicide with low toxicity and short residual period. However, its desulfurization metabolite, prothioconazole-desthio (PTC-d), is more persistent and has higher toxicity in terrestrial animals. In this study, the toxicokinetics (TK) and tissue distribution of PTC and PTC-d in Chinese lizards (Eremias argus) were measured following single oral dose (100 mg kg−1 body weight) treatments. TK parameters indicated that PTC was more rapidly absorbed than PTC-d, as indicated by its shorter time to reach peak concentrations in most tissues. Furthermore, the relative bioavailability of PTC in lizards was lower than that of PTC-d. Compared with PTC, PTC-d preferentially accumulated in lizards, as reflected by longer half-life of PTC-d. During the distribution process, PTC-d generated in vivo was transported from other tissues and was deposited in the skin and tail, where PTC-d may be excreted by exuviation or tail detachment. Preferential enrichment of S-enantiomer of both PTC and PTC-d were observed in all tissues. Hepatic cytochrome P450 gene expression measurement revealed that cyp1a5 and cyp3a28 exhibited the strongest responses in both treatment groups. In addition, the opposite responses of cyp2k4 in different treatment groups may indicate that this enzyme caused differences in the rates of metabolism of the two chemicals. This study compared the TK profile of PTC and its desulfurization metabolite PTC-d in lizards and demonstrated that the desulfurization of PTC could increase its ecological risk due to the higher bioavailability and persistence of PTC-d.

The Sox (SRY-related high-mobility-group box) family of genes shares a conserved HMG box and is involved in a diverse range of developmental processes and sex determination in vertebrates. Twenty Sox genes are present in the genomes of humans and mice, but far less is known about the Sox gene family in reptiles. Using two pairs of highly degenerate primers designed from a multiple alignment of Sox amino acid sequences in several species, different positive clones were obtained from male and female Eremias multiocellata, a viviparous lizard which is subject to TSD (temperature-dependent sex determination). These clones were sequenced and identified. They are members of the SoxB (Sox2, Sox14), SoxC (Sox11, Sox12) and SoxE (Sox9a, Sox9b, Sox10) groups. No sex-specific differences were observed. Based on the amino acid sequence similarities, the phylogenetic analysis was carried out and these genes clustered with their orthologues. In addition, we found the gene duplication in E. multiocellata, it may be a mechanism to produce new functional genes.

An experiment on compensatory growth in lacertid lizards from a population in Suzhou, Anhui, eastern China, after different periods of starvation, was conducted from May to June and September to October 2001. All lizards used in this study were adult males. The experiment lasted for 24 days for each test group. Group C, S3, S6, S9 were deprived of food for 0 (control), 3, 6 and 9 days, respectively. Then each group was fed for the rest of the experimental period. There were significant differences in food intake and mass change among the experimental groups during the course of weight recovery. S9 had higher food intake and mass change than S3 and group C. There were no obvious differences in the apparent digestive coefficient (ADC) or assimilation efficiency (AE) among experimental groups. The results indicate that there was a compensatory effect in weight recovery following starvation, and that the compensatory effect mainly resulted from significant increase in feeding intensity during weight recovery.

We used Eremias brenchleyi as a model animal to examine differences in thermal tolerance, selected body temperature, and the thermal dependence of food assimilation and locomotor performance between juvenile and adult lizards. Adults selected higher body temperatures (33.5 vs. 31.7 °C) and were able to tolerate a wider range of body temperatures (3.4–43.6 vs. 5.1–40.8 °C) than juveniles. Within the body temperature range of 26–38 °C, adults overall ate more than juveniles, and food passage rate was faster in adults than juveniles. Apparent digestive coefficient (ADC) and assimilation efficiency (AE) varied among temperature treatments but no clear temperature associated patterns could be discerned for these two variables. At each test temperature ADC and AE were both higher in adults than in juveniles. Sprint speed increased with increase in body temperature at lower body temperatures, but decreased at higher body temperatures. At each test temperature adults ran faster than did juveniles, and the range of body temperatures where lizards maintained 90% of maximum speed differed between adults (27–34 °C) and juveniles (29–37 °C). Optimal temperatures and thermal sensitivities differed between food assimilation and sprint speed. Our results not only show strong patterns of ontogenetic variation in thermal tolerance, selected body temperature and thermal dependence of food assimilation and locomotor performance in E. brenchleyi, but also add support for the multiple optima hypothesis for the thermal dependence of behavioral and physiological variables in reptiles.

Annual variation of water content and energy value of the major energ y reserves were studied in adult lizard, Eremias brenchleyi , from a populati on in Suzhou, Anhui, eastern China. Monthly samples of the adult lizards were c olle cted during September to November 2001 and March to August 2002. The lizards wer e brought to our laboratory in Chuzhou Normal College. The lizards were killed b y freezing to -15℃, and then separated into carcasses (including tails), liver s and abdominal fat bodies. The three components were oven dried to constant mas s at 65℃, weighed and preserved frozen for later determination of composition. We extracted non polar lipids from dried samples (except abdominal fat bodies) in a Soxhlet apparatus for a minimum of 5 5 h using absolute ether as solvent. Th e amount of lipids in a simple was determined by subtracting the lipid free dry mass from total sample dry mass. We determined energy value of dried samples inc luding carcasses, livers, abdominal fat bodies and non polar lipids using an ad i abatic bomb calorimeter. Males and females differed in water contents of carcass and liver. Water contents of carcass and liver were all higher in males than in females. There were significant monthly changes in water contents and energy va lues of carcass (including lean carcass) and liver in both males and females. Si gnificant monthly changes in energy value s of abdominal fat bodies were also found in both sexes. Energy values of carcas s (including lean carcass) and liver were higher in males than in females, but t hose of liver lower in males than in females. Our results indicated that annual variations in the major energy reserves were correlated with the reproduction an d winter hibernation. Proper energy storage in breeding season of male would be help for to strengthen the ability of quick movement, while, that of female woul d be increase reproductive output and improve survival and fitness.
Lacertid lizards,Eremias brenchleyi were captured from field,and reared artificially.Laid eggs were incubated at 30 ℃ and -12 kPa (humidity).Whole eggs,eggshells,yolks,and embryos were weighed,and energy of certain components was determined at a series of time points.Data on the development of embryos and the transition of material and energy in eggs incubation were processed,resulting in:1)The duration of incubation averaged 35 days,and the egg in wet mass increased for absorbing moisture while incubating.2)The embryos employed about 10%,30% and 20% of the total egg energy in the periods of 0-20,20-30,and 30-35 days of incubation,respectively.3)The embryos grew slowly during the first 20 days,then grew rapidly.4)Approximately 63.4% dry material,32.7% non-polar lipids and 59.6% energy in the contents of fresh eggs were transferred to the hatchlings.5)Inorganic material in both yolk and eggshell was used by the embryos in development.The transition ratios of dry material and non-polar lipids as main energy-substance,and the proportion of residual yolk in hatchlings are lower than those reported for snakes.The lower ratios maybe related to the longer slow-phase of embryonic development in this species.

Influence of thermal and hydric environments on incubation eggs,embryonic use of energy and hatchling traits were studied in the lacertid lizards,Eremias brenchleyi,which were collected in Qianshan,Suzhou,Anhui,Eastern China.The eggs were incubated at temperatures of 27,30,and 33 ℃ on substrates with water potentials of 0 and -220 kPa using a 3×2 factorial design. Laid eggs were collected in one hour.Eggs were weighed at five-days intervals till hatchlings from eggs incubated.Each hatchling was thawed and separated into carcass,residual yolks,and fat bodies after measured and weighed.The components were preserved frozen for later determination of composition.All viable eggs increased in mass throughout the course of incubation due to absorption of water,and both thermal and hydric environments affected water exchanges between eggs and their surroundings.Final eggs incubated in wetter substrates (0 kPa) gained more mass than did eggs in drier substrates (-220 kPa) but at the same temperature;final eggs incubated at 27 and 30 ℃ gained more mass than did eggs at 33 ℃ but at the same substrate water potential.Incubation temperature significantly affected duration of incubation,and which decreased as incubation temperature increased,but substrate moisture and its interaction with temperature did not.Both incubation and substrate moisture did not affected hatching success.Substrate moisture and its interaction with temperature were unaffected almost all hatchling traits examined except residual yolk.However,Incubation temperature profoundly affected embryonic use of nutrients and size，mass,and residual yolk mass of hatchlings.33 ℃ was not a suitable incubation temperature for E.brenchleyi eggs,because eggs incubated at 33 ℃ produced smaller hatchlings that contained larger residual yolks than did eggs incubated at 27 ℃ and 30 ℃.Given that eggs incubated at 27 ℃ and 30 ℃ both produced well-developed hatchlings of which all measured variables were nearly the same,we conclude that 30 ℃ is better than 27 ℃ for incubation of E.brenchleyi eggs because of the shortened duration of incubation at 30 ℃.

Selected body temperature (Tsel),critical thermal maximum (Tcmax),critical thermal minimum (Tcmin),and influence of temperature on food assimilation and locomotor performance were studied in adult male lacertid lizards,Eremias brenchleyi,from a population in Suzhou,Anhui,eastern China.Tsel,Tcmax and Tcmin were 33.7,43.6 and 3.3℃,respectively.Temperature significantly affected food passage time,food intake,apparent digestive coefficient (ADC),assimilation efficiency (AE) and locomotor performance of lizards.The food passage time decreased with increase in temperature from 26 to 30℃ and increased at higher temperatures.Food intake,ADC and AE were lower at 26 and 28℃ than at higher temperatures.The sprint speed increased with increase in body temperature from 19 to 34℃,and then decreased dramatically at higher temperatures.The length of continuous locomotion was apparently greater at 31 and 34℃ than at other lower or higher temperatures,and decreased dramatically at the body temperatures higher than 36℃.The average number of stops in the racetrack was significantly greater in lizards with body temperatures higher than 34℃ than in those with body temperatures from 19 to 34℃.Our results suggest that the optimal body temperatures for locomotion are 31-34℃,and the body temperature has pervasive effects on food assimilation and locomotion performance in lizards Eremias brenchleyi.

Studies on the ontogenetic shifts in sexual dimorphism in head size (head length and width) and food habits of Eremias brenchleyi were studied. The results showed that adult E. brenchleyi had no obvious sexual dimorphism in body size (SVL). Both sexes differed in head size since hatching, with males having larger heads than females. This sexual dimorphism was much more pronounced between adults than between juveniles (including hatchlings), largely because the increase velocity of head size of males with SVL was faster than that of females. Hatchlings had relatively larger heads to SVL than juveniles and adults, presumably because E. brenchleyi embryos allocated relatively more resources for early survival and growth of hatchlings. Head size of both sexes overall showed an allometric growth pattern with SVL increase ontogeny.Lizards of different sizes and sexes differed, in certain degrees,in food niche breadth and niche overlap. However, no direct evidence showed a noticeable contribution of the divergence in head size to the segregation of food niche between males and females, thereby mitigating the competition between both sexes.

Adults selected higher body temperatures (33.5 vs. 31.7 degrees C) and were able to tolerate a wider range of body temperatures (3.4-43.6 vs. 5.1-40.8 degrees C) than juveniles. Within the body temperature range of 26-38 degrees C, adults overall ate more than juveniles, and food passage rate was faster in adults than juveniles. Apparent digestive coefficient (ADC) and assimilation efficiency (AE) varied among temperature treatments but no clear temperature associated patterns could be discerned for these two variables. At each test temperature ADC and AE were both higher in adults than in juveniles. Sprint speed increased with increase in body temperature at lower body temperatures, but decreased at higher body temperatures. At each test temperature adults ran faster than did juveniles, and the range of body temperatures where lizards maintained 90% of maximum speed differed between adults (27-34 degrees C) and juveniles (29-37 degrees C). Optimal temperatures and thermal sensitivities differed between food assimilation and sprint speed. Our results not only show strong patterns of ontogenetic variation in thermal tolerance, selected body temperature and thermal dependence of food assimilation and locomotor performance in E. brenchleyi, but also add support for the multiple optima hypothesis for the thermal dependence of behavioral and physiological variables in reptiles.

To assess the potential gestational effects on post-hatching morphology, locomotor performance, and early growth rate, we maintained gravid Eremias multiocellata under four constant treatment temperatures (25, 29, 31, and 35 °C). Ambient temperature had significant effects on some morphometric traits of offspring, including tail length, head size, forelimb length and hindlimb length, but not on body mass or snout-vent length. The data of females` body temperature indirectly support the maternal manipulation hypothesis. Juvenile E. multiocellata had better locomotor performance and faster early growth rate at 29 °C than at the other three treatment temperatures (25, 31, and 35 °C). Our results suggest that gestation temperature may be optimized at 29 °C for E. multiocellata from Tianzhu, Gansu Province, China.

The paper deals with the study of the comparative osteological collection of extant amphibians and reptiles deposited in the Department of Palaeontology of the National Museum of Natural History, NAS of Ukraine. The collection has been recently catalogued and here is described for the first time. It consists of 407 storage units represented by complete or fragmented dry skeletons, skulls, and isolated bones belonging to 104 species of 65 genera, 23 families, and five orders (Caudata, Anura, Crocodilia, Testudines, Squamata). The collection also includes bones of 12 species currently listed in the Red Data Book of Ukraine: Salamandra salanandra, Lissotriton montandonti, Bombina (bombina) variegata, Rana dalmatina, Pseudopus apodus, Mediodactylus kotschyi, Lacerta viridis, Coronella austriaca, Elaphe dione, Zamenis situla, Zamenis longissimus, and Vipera renardi. Collection materials were collected at different times (from the last third of the 19th century until the present day) in 16 countries in Europe, Asia, and Africa. In terms of further enrichment, the collection can be used in batrachological and herpetological studies, and will be of interest for palaeontologists, archaeozoologists, and morphologists who work with osteological materials.

We studied the embryonic use of material and energy during incubation and hatchling traits in the lacertid lizards Eremias argus, which were collected from a mountain population in Langyashan, Chuzhou, eastern China in April, 2005. We randomly selected one egg from eleven clutches, opened and separated them into shell and contents, the other eggs were incubated at naturally fluctuating temperature (varying from 14.0 to 37.0 ℃) using wet vermiculite as the incubation substrate, of which the moisture was kept at -12 kPa water potential. The incubation length of first clutches and second clutches averaged 37.5d and 33.0d, respectively. The wet mass of eggs increased for absorbing moisture while incubating, but no significant difference of the final wet mass was founded between first clutches and second clutches. Fluctuating temperature significantly affected Fat body dry mass, but it did not affect hatching success, sex ratio, snout-vent length, tail length, body wet mass, body dry mass, carcass dry mass and residual yolk dry mass of hatchlings. Fat body dry mass from higher fluctuating temperature was greater than did that from lower fluctuating temperature. Incubation temperature affected some norphological traits of hatchlings, with hatchlings from higher temperature having larger hindleg length and tympanum length than did those from lower temperature. Embryo from higher temperature used much calcium than did that from lower temperature. During incubation, approximately 57.5% of dry material, 27.8% of non-polar lipids and 47.4% of energy in the yolk of freshly laid egg was transferred to the hatchling. There was not significant clutch variation of embryonic use of material and energy and hatchling traits in Eremias argus [Acta Zoologica Sinica 52(6): 1169 – 1173, 2006].

Based on the Giemsa-dyeing karyotypes and silver-staining bands of 15 populations from different localities in China belonging to 6 species of the genus Eremias , We found all species studied have 19 pairs of chromosomes, the size of chromosomes reduces gradually and there are no marked differences between the arranged pairs of macrochromosomes except the last pair of microchromosome. There are the same karyotype formula as 2n=38=36I+2m with NF=38 in E. argus, E. multiocellata, E. velox, E. arguta and E. grammica; but the karyotype formula of E. vermiculata is different as 2n=38=12V+2sI+22I+2m with NF=50. The NOR are all located on one small pair in female of E. velox, and E. arguta , in male of E. grammica and E. vermiculata ,and in both male and female of E. multiocellata. We have not found two or more than two pairs of NOR. Having one pair of NOR may be common in Genus Eremias and also the trait of Eremias. We speculate that the derivation of the karyotype of E. vermiculata had two possible way: one experienced the stage of triploid, and later the Robertsonian transposal of chromosomes; the other way was through the inversions between the arms on the chromosome and the phenomenon of inversions might occur during or subsequently after the upheaval of the Tibet and Qinghai plateau and the founding of the Tianshan . With regard to the trend of the evolution of chromosomes in the lizards (), the karyotype of E. vermiculata is more advanced. Making specialties of E. vermiculata will help in building the phylogenic tree of Eremias. In both male and female of the species studied, the heteromorphic sex-chromosomes were not found.

The major histocompatibility complex (MHC) genes have been well characterized in mammals, birds, amphibians and fishes, but little is known about their organization in reptiles, despite the fact that reptiles occupy an important phylogenetic position for understanding the evolutionary history of vertebrates MHC genes. In this study we used polymerase chain reaction (PCR) and reverse transcription- polymerase chain reaction (RT-PCR) to amplify the genomic exon 3 and exon 4 fragments of MHC class I genes in three racerunner lizards, including viviparous Multiocellated Racerunner (Eremias multiocellata), viviparous Gobi Racerunner (Eremias przewalskii), and oviparous Ordos Racerunner (Eremias brenchleyi). We also presented the molecular characterization of class I sequences for racerunner lacertids. Gene duplication was detected in the three Eremias species, at least four MHC class I loci in Multiocellated Racerunners and Ordos Racerunners, and at least five in Gobi Racerunners. A putative class I pseudogene was inferred in Ordos Racerunner for a premature stop codon in a segment of so-called exon 3. The peptide binding region, β2-microglobulin interaction sites and a conserved cysteine residue were recognized in α2 domain encoded by exon 3. The β2-microglobulin interaction sites, CD8 molecule interaction sites and a conserved cysteine residue were recognized in α3 domain encoded by exon 4. Putative classical class I genes were expressed in the uterus of both oviparous and viviparous racerunners during pregnancy, along with some alleles unexpressed in uterine. In addition, phylogenetic reconstruction suggested the existence of trans-species polymorphism in MHC class I genes in Eremias. These findings provide clues for further investigations of co-evolution of viviparity and maternal immune system, as well as evolution of squamate MHC.

主要组织相容性复合体（Major histocompatibility complex，MHC）是有颌脊椎动物基因组中的一个高度多态性的基因家族，与免疫系统密切相关，MHC基因特征在哺乳类、鸟类、两栖类和鱼类中已被较好地描述. 为了解爬行动物MHC基因的序列特征，通过PCR技术从胎生种密点麻蜥（Eremias multiocellata）、荒漠麻蜥（Eremias przewalskii）及卵生种山地麻蜥（Eremias brenchleyi）的肝脏中克隆了MHC I类基因外显子3和4的DNA片段，采用RT-PCR（逆转录-PCR）从这3种麻蜥的妊娠期子宫组织克隆了这两个外显子的cDNA片段. 结果表明，3种麻蜥MHC I类基因均发生基因重复，密点麻蜥和山地麻蜥至少有4个基因座位，荒漠麻蜥至少有5个基因座位. 在山地麻蜥获得的其中一条DNA片段中编码氨基酸的密码子突变为终止密码子，推测其为MHC I类基因的假基因. 在外显子3编码的α2结构域中检测到多个多肽结合位点和β-2微球蛋白结合位点以及一个保守的半胱氨酸位点. 在外显子4编码的α3结构域中检测到多个β-2微球蛋白结合位点和CD8分子结合位点以及一个保守的半胱氨酸位点. 基于氨基酸的系统发育分析提示3种麻蜥的子宫均表达经典的MHC I类基因，可能有一些MHC基因座位未在子宫中表达. DNA系统发育重建揭示3种麻蜥MHC I类基因谱系没有表现出物种特异性进化，而表现出跨种多态性. 上述结果为进一步研究胎生繁殖方式与母体免疫系统的协同进化及有鳞目MHC的演化奠定了基础.

The body temperature (Tb) and standard metabolic rate (SMR) of female Eremias multiocellata Günther, 1872, a viviparous lizard, were measured at 25, 30, and 35 C during pregnancy and after parturition to assess energy requirement of reproduction. The results showed that the Tbs of female lizards were slightly higher than actual ambient temperature in the 25 and 30 C groups, while they were slightly lower than ambient temperature in the 35 C group. Ambient temperature significantly affected SMR and gestation period of females. Energy requirement was constant in nonpregnant females, whereas it was increased in pregnant females. The maximal estimates of maintenance costs of pregnancy (MCP) were 4.219, 4.220, and 4.448 mg CO2•min–1, which accounted for 19.40%, 14.15%, and 12.32% of the total metabolic rate in the 25, 30, and 35 C group, respectively. The results indicated the MCP was an important component of total energy cost for the lizard E. multiocellata and the MCP in this lizard incurs a relative fixed energetic cost irrespective of ambient temperature.

The karyotype of some local populations of Eremias arguta from the Samara and Saratov Trans-Volga regions is described. The diploid set of multi-coloured lizards of both the Trans-Volga populations includes 38 chromosomes 2n = 38, NF = 38. All the chromosomes are acrocentric, gradually decreasing in size. The karyotype structure of females and males is 2n = 35M + 3m and 2n = 36M + 2m, respectively. The presence of nucleous organizers on telomeric sites of three (2nd, 4th, and 7th) and four (1st, 2nd, 4th and 9th) pairs of autosomes for the Saratov and Samara Trans-Volga regions, respectively, is a feature of the E. arguta karyotypes of these populations. In this connection, further comparative analysis of the chromosome sets of E. arguta from various sites of its habitat seems promising.

Eremias argus often produces two clutches per breeding season in Chuzhou, Anhui Province, with females laying 2 to 5 eggs per clutch. Clutch size and clutch mass was positively correlated to female size (SVL); relative clutch mass was independent of female size; egg was independent of clutch size. There was no inter-clutch difference in clutch size, clutch mass and egg mass. Egg length was positively correlated to egg width. Egg length was negatively correlated to clutch size; and egg width was independent of clutch size. Females increased reproductive output mainly through increasing clutch size.

Understanding community assembly is a fundamental goal of ecology and evolutionary biology, because it provides insight into how a given landscape changes in a synergistic fashion. With the current background of global environmental change, studies of how habitat alteration affects local communities often focus on species` responses to community-level changes instead of responses to specific ecological factors that elucidate the roles each factor plays in the final synergistic response. Here, we focus on the specific ecological mechanisms that drive changes in community structure. We investigated compositional patterns of lizard communities among natural and altered habitats (vegetatively sparse, natural, and dense) in the desert steppe ecosystem of Inner Mongolia, China. Habitat alteration induced significant changes in community composition of lizards and was associated with significant changes in both biotic and abiotic niches. Our preference (soil, thermal, and prey) and performance (locomotor, antipredator, and competitive) experiments identified many of the biotic and abiotic factors shaping lizard community responses to habitat change. In the natural habitat, where Phrynocephalus frontalis and Eremias multiocellata codominate, P. frontalis experienced low overlap (across lizard species) in preferred prey. Eremias multiocellata preferred the thermal environment of the natural habitat (and dense habitat), but this one factor did not fully explain its codominance. Phrynocephalus frontalis dominated in the sparse habitat, where this lizard species experienced its preferred tight soil and warm thermal environment and experienced low overlap of preferred prey. In the dense habitat, where E. argus dominates, P. frontalis and E. multiocellata exhibited impeded locomotor performance, whereas E. argus was not impeded by vegetation density. Eremias argus also preferred the thermal environment of the dense habitat (and natural habitat). Our results suggest, furthermore, that adult predation risk was not a major determinant of community divergence among habitats and that competition likely plays a more important role. Interspecific competition for microhabitat use may explain the low abundance of E. argus in the natural habitat and the low abundance of P. frontalis in the dense habitat. Overall, our assessment of lizard preferences and performances explained community composition across habitats. Our focus on ecological mechanisms associated with habitat alteration highlights the importance of vegetation conservation in lizard community management.
