Strict consistency between genetic and topographic landscapes of the brown tree frog (Buergeria robusta) in Taiwan

► 564 brown tree frogs from 31 drainages were sequenced for phylogeographic analysis. ► The eastern and western populations showed a prominent genetic divergence. ► Genetic landscape presented extremely high congruence to the topography of Taiwan. ► Post-glacial expansion was strongly and consistently supported by different analyses.
