Postglacial colonization of the Qinling Mountains: phylogeography of the swelled vent frog (Feirana quadranus).

ABSTRACT:

Background

The influence of Pleistocene climatic fluctuations on intraspecific diversification in the Qinling-Daba Mountains of East Asia remains poorly investigated. We tested hypotheses concerning refugia during the last glacial maximum (LGM) in this region by examining the phylogeography of the swelled vent frog (Feirana quadranus; Dicroglossidae, Anura, Amphibia).

Methodology/principal findings

We obtained complete mitochondrial ND2 gene sequences of 224 individuals from 34 populations of Feirana quadranus for phylogeographic analyses. Additionally, we obtained nuclear tyrosinase gene sequences of 68 F. quadranus, one F. kangxianensis and three F. taihangnica samples to test for mitochondrial introgression among them. Phylogenetic analyses based on all genes revealed no
