Phylogeography of Diptychus maculatus (Cyprinidae) endemic to the northern margin of the QTP and Tien Shan region.

ABSTRACT:

Background

Phylogeography and historical demography of the cyprinid fish Diptychus maculatus (subfamily Schizothoracinae) are evaluated across three river systems in the Northern Qinghai-Tibetan Plateau (QTP) and Tien Shan range: the Indus River, Tarim River and Ili River.

Results

Results from both mtDNA (16S rRNA, Cyt b and D-loop) and nucDNA (RAG-2) resolved four reciprocally monophyletic clades, representing populations from Indus River, South Tarim River, North Tarim River and Ili River, respectively. The divergence times was estimated to be 1.5-2.5 Mya. It is consistent with the hypothesis that the split of four clades is the consequence of vicariance resulting from both the intensive uplift of QTP and Tien Shan as well as the resultant expansion of the Taklimakan Deser
