Pleistocene-dated biogeographic barriers drove divergence within the Australo-Papuan region in a sex-specific manner: an example in a widespread Australian songbird

摘要

The ranges of the currently accepted grey shrike-thrush subspecies: blue— , red— , purple— , green— and yellow— , and contemporary and putative historical biogeographic barriers and relevant geographic regions (Schodde and Mason ).

( ) is also shown (same colours apply); here we considered the King Island and Tasmanian lineages as one because their ranges overlap
