Current genetic variation patterns across different geographic areas are mainly the result of various historical processes, including paleoclimate oscillations and tectonic events. Southern China, characterized by a complex paleoclimate and topography, presents an opportunity to examine such genetic variation patterns. Herein, we selected three species of moustache toads (Leptobrachium boringii, Leptobrachium liui and Leptobrachium leishanense) distributed across southern China to elucidate historical processes that shaped their current phylogeographic patterns based on two mitochondrial genes...
