Abstract

Abstract: This study used the mitochondrial DNA cytochrome b and control region sequences to examine the population genetic structure of Microphysogobio brevirostris, an endemic cyprinid species in northern Taiwan. In total, 90 specimens were collected from six populations belonging to four major rivers. All haplotypes were identified as two major clades (Clades N and S), exhibiting a southern and a northern distribution. The results of statistical dispersal-vicariance analysis (S-DIVA) revealed that two vicariance events and one dispersal event shaped the phylogeographic pattern of M. brevirostris . These results suggest that the ancestral populations of M. brevirostris are widely distributed throughout northern Taiwan, north of the Miaoli Plateau. The ancestral populations then diverged into two clades (N and S) by the raising of the Taoyuan Plateau. Finally, two major rivers of the S clade diverged and dispersed into adjacent rivers. Besides, our results revealed that Microphysogobio alticorpus and M. brevirostris colonized Taiwan during the same ice age through different colonization routes. Highlights: The ancestral populations of Microphysogobio brevirostris were widely distributed and diverged into two clades (N and S). S-DIVA revealed two vicariance events and one dispersal event shaped the phylogeographic pattern of M. brevirostris . M. alticorpus and M. brevirostris colonized Taiwan during the same ice age through different colonization routes.
