Abstract Protected Areas (PAs) are the cornerstone of biodiversity conservation. Here, we collated distributional data for >14,000 (~70% of) species amphibians and reptiles (herpetofauna) to perform a global assessment conservation effectiveness PAs using distribution models. Our analyses reveal that >91% herpetofauna currently distributed in PAs, this proportion will remain unaltered under future climate change. Indeed, loss species’ ranges be lower inside than outside them....

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...

In the arid landscapes of Arabian Peninsula, high levels cryptic diversity among reptiles, and especially in geckos, have recently been revealed. Mountain ranges within peninsula were shown to contain highest richness reptile endemicity, serving as refugia species less adapted hyper-arid conditions lowlands. With up 19 endemic species, Hajar Mountains southeastern Arabia are a clear example this pattern. Owing its old geological history, complex topography geographic isolation from rest...
The geological history of the Arabian Peninsula has played a crucial role in shaping current diversity and distribution patterns many African faunal elements. gecko genus Hemidactylus is not an exception. In this study, we provide insight into phylogeny systematics 45 recognized species so-called Arid clade from Arabia, Horn Africa, Levant Iran. material comprises 358 specimens sequenced for up to two mitochondrial (12S rRNA, cytochrome b) four nuclear (mc1r, cmos, rag1, rag2) genes with...
Abstract Scaling evolutionary trees to time is essential for understanding the origins of clades. Recently developed methods allow including entire fossil record known group interest and eliminated need specifying prior distributions node ages. Here we apply fossilized birth-death (FBD) approach reconstruct diversification timeline viperines (subfamily Viperinae). Viperinae are an Old World snake subfamily comprising 102 species from 13 genera. The vipers fairly rich well assignable clades...
Abstract Aim Deserts are generally perceived as areas of low diversity, and hence receive little attention from researchers conservationists. Squamates the dominant group vertebrates in arid regions, such represent an ideal model to study biodiversity patterns these areas. We examine spatial evolutionary history endemism terrestrial squamates Arabian Peninsula test hypotheses on role topography isolation so identify possible environmental drivers diversification.

Abstract The geographic distribution of biodiversity is central to understanding evolutionary biology. Paleogeographic and paleoclimatic histories often help explain how biogeographic patterns unfold through time. However, such are also influenced by a variety other factors, as lineage diversification, that may affect the probability certain types events. complex well-known geologic climatic history Afro-Arabia, together with extensive research on reptile systematics in region, makes...

The desert vipers of the genus Cerastes are a small clade medically important venomous snakes within family Viperidae. According to published morphological and molecular studies, group is comprised by four species: two morphologically similar phylogenetically sister taxa, African horned viper (Cerastes cerastes) Arabian gasperettii); more distantly related species, Saharan sand vipera), enigmatic Böhme's boehmei), only known from single specimen in captivity allegedly captured Central...
