Relationships of lacertid lizards were assessed on the basis of 84 primary and 112 binary characters drawn mainly from morphology, including features of the skeleton, external anatomy, various internal soft part systems and two aspects of behaviour. Among features not previously used, or not fully investigated before, are structure of the septomaxilla and nasal passages, arranged of the xiphisternal cartilages, mite pockets, kidney position, ulnar nerve arragement, thoracic fascia, aspects of the hemipenis and its associated muscles, female genitalia and jaw muscles. On the basis of parsimony analysis and compatibilty treatment of this character set, the Lacertidae fall into two main portions: A paraphyletic Palaearctic and Oriental group of primitive forms, from which is derived a holophyletic assemblage of Ethiopian and advanced Saharan and Eurasian taxa. The former group ist not fully resolvable, but Psammodromus and Gallotia appear to be sister groups and are probably related to Lacerta parva and L. fraasi and then L. brandtii, Podarcis appears to be related successively to L. andreanszkyi, the sister species L. dugesii and L. perspicillata, and perhaps L. danfordi and L. laevis. This assemblage may be related to archaeolacertas and Algyroides. The separation of Lacerta lepida, L. pater and L. princeps from the agilis group, based on chemical evidence, is weakly contradicted by morphology. Takydromus may be most closely related to L. vivipara, and L. jayakari and L. cyanura constitute the most likely sister group of the Ethiopian and advanced Saharo-Eurasian assemblage. Taxe in the Ethiopian and advanced SaharoEuroasian assemblage form a long essentially pectinate tree with relatively change between the side branches, except for a strong disjunction separating the more primitive from the more advanced taxa. Most of the former fall on two main branches, with ´Lacerta` australis and ´L.` rupicola possibly basal to them. 1. the Equatorial forest group containing Gastropholis, Bedriagaia, ´Lacerta` echinata, Adolfus, ´Lacerta` jacksoni and Holaspis. The first three of these constitute a holophyletic group and the same is probably true of the remainder. 2. Tropidosaura, Poromera and Nucras, the latter being the sister group of the more advanced forms. These include successively the Ethiopian Philochortus, Latastia, Ichnotropis and Heliobolus, Pseuderemias, Meroles and Aporosaura, and Pedioplanis, and then the Saharo-Eurasian Eremias, Acanthodactylus, Mesalina and Ophisops-Cabrita. It seems probable that the ancestors of modern Lacertidae arose in western Eurasia, where the family is known since the Palaeocene and is still represented there largely by quite primitive forms (89 species and seven nominal genera). The family later invaded Africa, perhaps first in the early or middle Miocene. Relatively primitive lacertids spread widely in largely mesic situations in the Ethiopian region, radiating to some extent (six present genera and 16 species) and producing Nucras and the related series of advaned groups (eight genera and 54 species) whoich show increasing adaptation to xeric environments. These genera tend to have heir most primitive species in the northeast and north of the Ethiopian region. The most advaned gave rise to the Saharo-Eurasian clade, now made up to Eremias, Acanthodactylus, Mesalina and Ophisops-Cabrita. This invaded the arid areas of North Africa and Eurasia, where it is presently represented by 70 species. Many morphological changes in increasingly advanced lacertids may be functionally related to the problems of survival in arid, hot, open environments. Considerable ecological parallelism exists in lacertids, with members of separate stocks occupying similar niches in different geographical areas. Morphological adaptations associated with these niches contribute significantly to the high levels of character homoplasy found in the family. There is also some correlation between the degree of niche differentiation in various groups and the quality of the phylogenies that can be produced from their physical characters. A number of morphological parallels exist between advaned lacertids and New World macroteiids. In the skull at least, advaned lacertids show a complex mixture of paedomorphosis and acceleration. Nomenclatorial changes are as follows: Cabrita is synonymised with Ophisops, necessitating a new name, Ophisops nictans, for Cabrita jerdonii. Aporosaura is synonymised with Meroles, Platyplacopus with Takydromus, and Bedriagaia with Gastropholis. ´Lacerta` (or Centromastyx) echinata is also transferred to the latter genus and Lacerta jacksoni to Adolfus. ´Lacerta` australis and ´L.` rupicola are put in a new genus, Australolacerta. It is recommended that Lacerta dugesii and L. perspicillata should not be placed in the otherwise very uniform genus Podarcis. Although clearly paraphyletic, Lacerta s. lat. Should be retained at least for the present and, if necessary putative relationships within it indicated by informal groups or subgenera.

DNA sequence indicates the Lacertidae contain two subfamilies, Gallotiinae and Lacertinae, the latter comprising two monophyletic tribes, the Eremiadini of Africa and arid southwest and central Asia, and the Lacertini of Europe, northwest Africa and southwest and east Asia. Relationships within the 108 species of Lacertini are explored using mtDNA (291 bp cytochrome b; 329 bp 12S rRNA for 59 nominal species, and reanalysis of the data of Harris et al. 1998, and Fu 2000). The morphology of the tribe is reviewed and 64 of its characters (equivalent to 83 binary ones) also used to assess relationships. The Lacertini are assigned to 19 monophyletic units of 1 to 27 species, recognised here as the following genera (contents are indicated in brackets): Algyroides, Anatololacerta gen. nov. (L. danfordi group), Apathya (L. cappadocica group), Archaeolacerta (L. bedriagae), Dalmatolacerta gen. nov. (L. oxycephala), Darevskia (L. saxicola group), Dinarolacerta gen. nov. (L. mosorensis), Hellenolacerta gen. nov. (L. graeca), Iberolacerta (L. monticola group), Iranolacerta gen. nov. (L. brandtii and L. zagrosica), Lacerta s. str. (sand and green lizards, L. agilis group), Parvilacerta gen. nov. (L. parva and L. fraasii), Phoenicolacerta gen. nov. (L. laevis group), Podarcis (wall lizards), Scelarcis (L. perspicillata), Takydromus (Asian grass lizards), Teira (L. dugesii), Timon (ocellated lizards, L. lepida group) and Zootoca (L. vivipara). Both mtDNA and morphology indicate that Lacerta and Timon are sister taxa, and DNA suggests further possible relationships among genera (Fig. 1, p. 6). Neither DNA nor morphology indicates that the archaeolacertas (sometimes formalised as Archaeolacerta sens. lat.) form a clade. Instead, they are representatives of an ecomorph associated with living on rock exposures and using the narrow crevices that these contain. The Lacertidae probably arose in the European area, with the Gallotiinae later reaching Northwest Africa and the Canary Islands, and the ancestor of the Eremiadini invading Africa in the mid-Miocene. The Lacertini spread through much of their present European range and diversified, perhaps largely by repeated vicariance, around 12–16 My ago, producing the ancestors of the present mainly small-bodied genera, which then underwent often modest speciation. Three units spread more widely: the Lacerta-Timon clade of large-bodied lizards probably dispersed earliest, followed by Algyroides and then Podarcis. Overall, European Lacertidae show a pattern of repeated spread, often accompanied by restriction of previous groups. Expansion of Lacertini may have displaced earlier lacertid lineages from all or much of Europe; while spread of Podarcis may have restricted many other genera of Lacertini. The earlier expansion of the Lacerta-Timon clade probably did not have this effect, as difference in adult body size restricted competitive interaction with other forms. Several invasions of more distant areas also occurred: of East Asia by Takydromus over 10 My ago, and more recently of northwest Africa by Podarcis, Scelarcis and Timon, and Madeira by Teira. Relationships within the Eremiadini estimated from both mtDNA, and nDNA differ considerably from those based on morphology. They indicate relatively mesic forms may have diversified widely across Africa and given rise to at least three independent invasions of arid habitats. MtDNA also indicates that Lacerta andreanskyi belongs in the Eremiadini and may occupy a basal position there. It is assigned to a further new genus, Atlantolacerta gen. nov.

Apathya is a lacertid genus occurring mainly in south-east Turkey and its adjacent regions (part of Iran and Iraq). So far two morphological species have been attributed to the genus, i.e. A. cappadocica (with five subspecies, A. c. cappadocica, A. c. muhtari, A. c. schmidtlerorum, A. c. urmiana and A. c. wolteri) and A. yassujica. The first of them occupies most of the genus’ distribution while A. yassujica is endemic of the Zagros Mountains. The topology and the genetic distances retrieved from this study, reveal that Apathya is a highly variable genus, which comes in agreement with the high morphological variation found in previous studies. Such levels of morphological differentiation and genetic divergence often exceed those between species of other Lacertini genera that are already treated as full species, justifying our view that the genus requires taxonomical revision. The phylogeographical scenario proposed reveals that dispersal and vicariant events in Anatolia and Southwest Asia throughout the Miocene, Pliocene, and Pleistocene resulted in the present distribution of the genus under study. Key geological event for the understanding of the phylogeography of the genus is the movement of the Arabian plate that led to the configuration of Middle East specifically the formation of the mountain ranges of Turkey and Iran.

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.

Little is known about altitudinal distribution of lizards in Iran. In the present study we studied distribution pattern of members of family Lacertidae along the eleveatinal gradient in Iran. To determine environmental drivers of distribution pattern of 48 lizard species, all known valid members of family Lacertidae, along elevational gradient in Iran. Firstly, we classified Iran digital elevation model (DEM) based on 100m intervals, that resulted in 56 altitudinal bands and number of species in each band was recorded. Secondly, we extracted mean value of following variables; altitude, slop, area, solar radiation index (SRI), normalized differences vegetation index (NDVI), annual precipitation, precipitation of wettest month, precipitation of driest month precipitation, precipitation of wettest quarter, precipitation of driest quarter, and precipitation of warmest quarter, and using VIF measure correlated variables were removed. Finally, we performed a multiple regression and found that area and precipitation of warmest quarter are the most important drivers of distribution pattern of family Lacertidae along elevational gradient in Iran. General distribution pattern of family Lacertidae was unimodal and maximum number of species living from 1475 m to 1675 m.

Mountains play a key role in forming biodiversity by acting both as barriers to gene flow among populations and as corridors for the migration of populations adapted to the conditions prevailing at high elevations. The Anatolian and the Zagros Mountains are located in the Alpine-Himalayan belt. The formation of these mountains has influenced the distribution and isolation of the animal population since the late Cenozoic. Apathya is a genus of lacertid lizards distributed along these mountains with two species, i.e., Apathya cappadocica and Apathya yassujica. The taxonomy status of lineages within the genus is complicated. In this study, we tried to collect extensive samples from throughout the distribution range, especially within the Zagros Mountains. Also, we used five genetic markers, two mitochondrial (COI and Cyt b) and three nuclear (C-mos, NKTR, and MCIR), to resolve the phylogenetic relationships within the genus and explain several possible scenarios that shaped multiple genetic structures. The combination of results in the current study indicated eight well-support monophyletic lineages that separated to two main groups; group 1 including A. c. cappadocica, A. c. muhtari and A. c. wolteri, group 2 contains four regional clades Turkey, Urmia, Baneh and Ilam, and finally a single clade belonging to the species A. yassujica. In contrast to previous studies, Apathya cappadocica urmiana was divided into four clades and three clades were recognized within Iranian boundaries. The clades have dispersed from Anatolia to adjacent regions in the south of Anatolia and the western Zagros Mountains. According to the evidence generated in this study this clade is paraphyletic. Based on our assumption, orogeny activities and also climate fluctuations in Middle Miocene and Pleistocene have influenced to formation of lineages. In this study we revisit the taxonomy of the genus and demonstrate that the species diversity was substantially underestimated. Our findings suggest that each of the eight clades corresponding to subspecies and distinct geographic regions deserve to be promoted to species level.

Apathya is a lacertid genus occurring mainly in south-east Turkey and its adjacent regions (part of Iran and Iraq). So far two morphological species have been attributed to the genus; A. cappadocica (with five subspecies, A. c.cappadocica, A. c.muhtari, A. c.schmidtlerorum, A. c. urmiana and A. c.wolteri) and A.yassujica. The first species occupies most of the genus’ distribution range, while A. yassujica is endemic of the Zagros Mountains. Here, we explored Apathya’s taxonomy and investigated the evolutionary history of the species by employing phylogenetic and phylogeographic approaches and using both mitochondrial (mtDNA) and nuclear markers. The phylogenetic relationships and the genetic distances retrieved, revealed that Apathya is a highly variable genus, which parallels its high morphological variation. Such levels of morphological and genetic differentiation often exceed those between species of other Lacertini genera that are already treated as full species, suggesting the necessity for a taxonomic revision of Apathya. The phylogeographical scenario emerging from the genetic data suggests that the present distribution of the genus was determined by a combination of dispersal and vicariance events between Anatolia and Southwest Asia dating back to the Miocene and continuing up to the Pleistocene. Key geological events for the understanding of the phylogeography of the genus are the movement of the Arabian plate that led to the configuration of Middle East (orogenesis of the mountain ranges of Turkey and Iran) and the formation of Anatolian Diagonal.

Sexual size dimorphism in the Iranian endemic Yassujian lizard, Apathya yassujica (Nilson et al., 2003), was previously undocumented. In this study 23 male and 19 female adult specimens of A. yassujica were collected from Kohguiluyeh va Boyer Ahmad and Fars Provinces in southwestern regions of the Iranian Plateau. Univariate and multivariate analyses performed on morphometric data showed that males are larger than females, and except for number of scales from collar to anal plate and that all other sexual differences were male-biased. We also further the previous range of A. yassujica with records from different regions of Fars province, southwestern Iran

Aims The Zagros Mountains are a part of the 20th global hotspot, the Irano-Anatolian biodiversity hotspot. In this study, we aim to develop a comprehensive checklist of endemic herpetofauna species in the Zagros Mountains as one of the biodiversity hotspot regions, to provide more information about this important area and the necessity of conservation programs to protect it. Materials & Methods The Zagros Mountains, with an area of about 533,543km2, ranges from Turkey and Iraq to western and southwestern Iran along the eastern edge of the Persian Gulf. A list of endemic species has been collected from the literature review. Findings This region contains 3 species and 7 subspecies of endemic amphibians belonging to three genera and two families, the Salamandridae (8) and the Bufonidae (2). Neurergus and Calliopersa are endemic to this hotspot. There are 40 species and 6 subspecies of endemic reptiles belonging to 24 genera and 10 families. The families with the greatest number of endemic species are the Gekkonidae, Phyllodactylidae, and Colubridae. Three genera, Asaccus, Mediodactylus, and Eirenis, dominate the region, with 32 endemic taxa. There are also two endemic genera, Parsigecko and Lakigecko. Conclusion Many amphibians in the Zagros Mountains, especially all the species of the genus Neurergus, are categorized in IUCN (the International Union for Conservation of Nature) Red List and CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). The habitats of the Zagros Mountains herpetofauna, especially those of endangered and endemic species, should be protected and managed to maintain or restore populations of the declining species.

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. Location World-wide. 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.

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.

During our long-term fieldwork on the Iranian plateau in 2000 and 2002, we collected and examined a series of lacertid lizards, belonging to the genus Lacerta from various parts of the Zagros Mountains of western and southwestern Iran, from a morphological point of view. Based on the collected material, two new taxa are described: Lacerta yassujica sp.n. and Lacerta brandtii esfahanica ssp.n. Based on all the available evidence, L. yassujica is closely related to Lacerta (Apathya) cappadocica. A short account on taxonomy and biogeography of the studied taxa is given.

The global struggle to conserve as many species as possible with limited resources requires an improvement of our knowledge on the distribution of biodiversity. In Iran, the state of knowledge is poor for most groups of organisms, except few vertebrate groups and vascular plants. Reptiles are one of the best known, most diverse vertebrate groups in Iran, with a high rate of endemism (ca. 29%), but distribution patterns and related environmental drivers remain poorly understood. In the present study, based on a large publicly available dataset, we use general additive modelling (GAM) to identify explanatory variables for species richness of reptiles in Iran. Results indicate heterogeneity parameters (range +entropy) as the variables with the highest explanatory values. Based on the grid cells of the predicted environmental richness, using hotspot analysis, we suggest seven hotspots of reptile diversity (HRDs) across the country. Our results corroborate the previously recognized HRDs and detect three additional ones, located alongside the major mountain ranges around the central deserts plateau, particularly in the Zagros Mountains. Four of the largest HRDs (ca. 90%) situate within the Irano-Anatolian and Caucasus global biodiversity hotspot. In addition, our results reveal a large gap between identified HRDs and the current network of protected areas (PAs) in the country. While three of the detected HRDs in this study are partially touched (ca. 18%) by the PA network, overall, these areas are only covered by less than 10%. Therefore, the effectiveness of the current PAs for the protection of the reptile diversity of Iran is questionable.

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.

We present an annotated checklist for a total 241 reptiles and 22 amphibians including 5 frogs, 9 toads, 7 newts and salamanders, 1 crocodile, 1 worm lizard, 148 lizards, 79 snakes and 12 turtles and tortoises, includes the most scientific literature up to August 2014 and also based on several field surveys conducted in different Provinces of Iran from 2009 to 2014. We present an up-to-dated checklist of reptiles and amphibians in Iran. We provide a comprehensive listing of taxonomy, names, distribution and conservation status of all amphibians and reptiles of Iran. This checklist includes all recognized named taxa, English names for classes, orders, families, species, subspecies along with Persian names for species, including indication of native and introduced species. For the first time we report two non-native introduced reptiles from natural habitats of Iran. Of the total 22 species of amphibians in Iran, 6 (27.2%) are endemic and of the total 241 species of reptiles, 55 (22.8%) are endemic. Of the 22 amphibians species in Iran, 3 (13%) are Critically Endangered, 2 (9%) are Vulnerable and of the 241 reptile species 3 (1.2%) are Critically Endangered, 4 (1.6%) are Endangered and 10 (4.1%) are Vulnerable. Accordingly, this paper combines significant aspects of taxonomy, common names, conservation status and distribution of the Iranian herpetofauna.

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.
