A new toad of Myers & Leviton, 1962 (Anura, Megophryidae) from Sichuan Province, southwest China.

A new species of the genus Myers & Leviton, 1962 is described from Sichuan Province, southwest China. Molecular phylogenetic analyses based on mitochondrial gene sequences clustered the new species as an independent clade nested with , , and . The new species could be distinguished from its congeners by a combination of the following characters: body size moderate (39.

A wide hybrid zone mediated by precipitation contributed to confused geographical structure of .

Confused geographical structure of a population and mitonuclear discordance are shaped by a combination of rapid changes in population demographics and shifts in ecology. In this study, we generated a time-calibrated phylogeny of , an endemic Xizang alpine toad occurring in mountain streams on the Qinghai-Xizang (Tibet) Plateau (QTP). Based on three mitochondrial DNA (mtDNA) genes, eight clades were assigned to three deeply divergent lineages.

Temperature and Diet Acclimation Modify the Acute Thermal Performance of the Largest Extant Amphibian.

The Chinese giant salamander (), one of the largest extant amphibian species, has dramatically declined in the wild. As an ectotherm, it may be further threatened by climate change. Therefore, understanding the thermal physiology of this species should be the priority to formulate related conservation strategies.
