Phylogeography of Triplophysa stenura (Nemacheilidae): Responded to the Mid-Pleistocene Climate Transition in the Qinghai-Tibetan Plateau.

ABSTRACT: Pleistocene climatic oscillations have greatly influenced the evolutionary histories and distribution patterns of most extant species. In this study, the phylogeographic patterns and evolutionary history of Triplophysa stenura were investigated. A total of 359 individuals from 19 locations covering the species' distribution range were collected, and two mitochondrial genes (COI and Cyt b) and the recombination activating protein 1 gene (Rag1) were analyzed. Two deeply divergent lineages, corresponding geographically to the northern and southern Tanggula Mountain, were observed, and shallow divergences were found within the southern and central Qinghai-Tibetan plateau (QTP). The estimated divergence time between the northern and southern Tanggula lineages was around 1.07 Mya.
