We describe three new species of Pristimantis from the upper montane forests and high Andean grasslands Pui Protected Forest its close surroundings (Región Junín, central Peru) compare them morphologically genetically with other taxonomically biogeographically relevant Pristimantis. All have skin on dorsum shagreen scattered tubercles, discontinuous dorsolateral folds, tuberculate flanks, venter areolate. bounides sp. nov. is known two localities outside in between 3350 3463 m a.s.l....
Mesalina are small lacertid lizards occurring in the Saharo‐Sindian deserts from North Africa to east of Iranian plateau. Earlier phylogenetic studies indicated that there several species complexes within genus and thorough taxonomic revisions needed. In this study, we aim at resolving phylogeny taxonomy M. brevirostris complex distributed Middle East Arabian/Persian Gulf region Pakistan. We sequenced three mitochondrial nuclear gene fragments, combination with delimitation species‐tree...
We present a comprehensive summary of the distribution lizards Iran accompanied by an annotated checklist. The updated maps all 146 species 41 genera 11 families are based on available bibliographic records, catalogues museum collections and our own field observations. final dataset used for contains 8525 georeferenced records cover 41% country when plotted grid 0.25° × resolution. is publicly accessible through GBIF portal (http://www.gbif.org/dataset/7db4f705-61ae-4c6e-9de2-06674e7d46b2)....
We describe a new minute species of the genus Pristimantis, P. boucephalus sp. nov., from Yanachaga-Chemillén National Park, Región Pasco, Peru. The description is based on freshly collected male specimen found at 2950 m a.s.l. in cloud forest and four previously unidentified museum specimens consisting two adult males, one subadult female juvenile Park. mainly characterized by snout–vent length 13.4–14.5 mm males (n = 3), 12.5 only known female, compared morphologically genetically with...
Sex chromosomes are believed to be stable in endotherms, but young and evolutionary unstable most ectothermic vertebrates. Within lacertids, the widely radiated lizard group, sex have been reported vary morphology heterochromatinization, which may suggest turnovers during evolution of group. We compared partial gene content Z-specific part across major lineages lacertids discovered a strong stability chromosomes. can conclude that common ancestor living around 70 million years ago (Mya),...
Genetic architecture of a species is result historical changes in population size and extent distribution related to climatic environmental factors contemporary processes dispersal gene flow. Population-size range contractions, expansions shifts have substantial effect on genetic diversity intraspecific divergence, which further shaped by gene-flow limiting barriers. The Balkans, as one the most important sources European biodiversity, region where many temperate persisted during Pleistocene...
ABSTRACT Dermal armour, consisting of bony dermal structures known as osteoderms (ODs), is widespread in squamate reptiles. However, some limbless taxa such snakes, ODs are rare, probably due to a trade‐off between mechanical protection and the demands locomotion consumption large prey. Recent findings restricted distal body regions sand boas ( Eryx , Erycidae) challenge this paradigm, suggesting they provide passive against aggressive prey without significantly impairing locomotion....
Tree frogs Hyla arborea and savignyi are similar, closely-related species distributed in Europe the Middle East. We investigated geographic variation body shape within between these species, tested its relationships to macroclimatic conditions. used morphometric distances (based on size corrected external measurements) construct phenetic trees (unweighted pair-group method of arithmetical averages, Neighbour-joining), test correlations morphology, geography, climate by partial Mantel test....
Tail autotomy and regeneration are less known in Sphenodon ('Reptilia': Rhynchocephalia) than Squamata. We examined museum specimens, guntheri (N = 8) punctatus 172), wild 19) sp. skeletons 8). In S. punctatus, unlike typical Squamata, sexes had similar relative (intact) tail lengths, frequencies; body growth was isometric. breakage usually intravertebral, followed by ablation of a variably sized terminal vertebral piece, partly deviating from lizards. Hypothetically, imperfect results...
The molecular phylogeny of Hemidactylus turcicus (sensu lato) and related Levantine taxa geckos were studied using mitochondrial DNA sequence data. Five main phylogenetic lineages detected within the distribution area H. turcicus: (1) stricto) from Mediterranean region comprising two widely distributed haplotype groups divergent by 2.1%; (2) cf. north-eastern Israel forming a (7.2%) sister lineage to s.s.; (3) lavadeserticus black Syrian basalt desert; (4) mindiae southern Jordan; (5) highly...
The gecko genus Hemidactylus, with its 132 currently recognized species, ranks among the most species-rich reptile genera. Recent phylogenetic studies disclosed unexpectedly high genetic variability and complex biogeographic history within arid clade distributed in Mediterranean, Northeast Africa, Middle East Indian subcontinent. Particularly, species from Arabian Peninsula have been lately subject of many taxonomic revisions that resulted descriptions 16 new taxa. Yet not all detected...
Climatic changes during the Pleistocene played an instrumental role in shaping recent distribution and diversity of Western Palearctic biota. Range oscillations often lead to allopatric differentiation followed by establishment secondary contact zones. As a result, many species are composed complex networks phylogenetic lineages with different histories. Pseudopus apodus is only surviving member ancient genus anguid lizards (Anguidae) distributed from Balkans through Anatolia Caucasus...
Abstract The slow-worm lizards ( Anguis ) comprise five species occurring throughout most of the Western Palearctic. Although these are relatively uniform morphologically – with exception A. cephallonica , which exhibits a quite unique morphology they genetically deeply divergent. Here, we provide detailed distribution maps for each and discuss their biogeography conservation based on updated genetic data robust database. We pay particular attention to so called ‘grey zone’, typically...
A new species of the Hypsiboas benitezi group is described from western Amazon Basin. The characterized by its medium size (SVL 24.4–31.2 mm in adult males, 26.0–36.0 females), absence nuptial excrescences, palpebral membrane lacking golden reticulation, and a mental gland males. dorsal surfaces living frogs are bright yellowish green to tan, frequently bear an X-shaped mark; parietal peritoneum, pericardium sclera covered guanophores. differs other members (H. benitezi, H. lemai,...
Acanthodactylus is a widespread lacertid genus occurring from the Iberian Peninsula and western North Africa to India including Middle East, Cyprus, Arabian Peninsula. The in dire need of taxonomic revision, phylogenetic relationships amongst within its species remain unclear. In particular, taxonomy relationship allopatric, narrow-ranged schreiberi close relative, boskianus asper, are poorly understood. We estimated phylogeographical structure A. across distribution range, evaluated b....
