Colobine monkeys constitute a diverse group of primates with major radiations in Africa and Asia. However, phylogenetic relationships among genera are under debate, recent molecular studies incomplete taxon-sampling revealed discordant gene trees. To solve the evolutionary history colobine to determine causes for possible tree incongruences, we combined presence/absence analysis mobile elements autosomal, X chromosomal, Y chromosomal mitochondrial sequence data from all recognized genera....
Gibbons or small apes inhabit tropical and subtropical rain forests in Southeast Asia adjacent regions, are, next to great apes, our closest living relatives. With up 16 species, gibbons form the most diverse group of hominoids, but number taxa, their phylogenetic relationships phylogeography is controversial. To further discussion these issues we analyzed complete mitochondrial cytochrome b gene from 85 individuals representing all gibbon including subspecies. Based on tree reconstructions,...
The Leptolalax applebyi group of Asian leaf-litter frogs currently comprises four species particularly small-bodied (<40 mm SVL) distributed in the Central Highlands Vietnam and northeastern Cambodia. In addition to their small size, is characterized by morphological genetic similarities, as well breeding habitat at headwaters mountain streams seeps. A recent study suggested that least two-thirds diversity remained hidden within morphologically cryptic lineages. We expand upon molecular,...

Abstract Aim Small geographic ranges make species especially prone to extinction from anthropogenic disturbances or natural stochastic events. We assemble and analyse a comprehensive dataset of all the world's lizard identify with smallest ranges—those known only their type localities. compare them wide‐ranging infer whether specific regions biological traits predispose have small ranges. Location Global. Methods extensively surveyed museum collections, primary literature our own field...

Pathogen pollution has caused dramatic losses of amphibian diversity on a global scale. The recently emerged chytrid fungus Batrachochytrium salamandrivorans ( Bsal ) been hypothesized to have its origin in Asian urodelan populations, from which it may introduced Europe through the trade live urodelans.
