Isolation, marine transgression and translocation of the bare-nosed wombat (Vombatus ursinus).

ABSTRACT: Island populations can represent genetically distinct and evolutionarily important lineages relative to mainland conspecifics. However, phenotypic divergence of island populations does not necessarily reflect genetic divergence, particularly for lineages inhabiting islands periodically connected during Pleistocene low sea stands. Marine barriers may also not be solely responsible for any divergence that is observed. Here, we investigated genetic divergence among and within the three phenotypically distinct subspecies of bare-nosed wombats (Vombatus ursinus) in south-east Australia that are presently-but were not historically-isolated by marine barriers. Using genome-wide single nucleotide polymorphisms, we identified three genetically distinct groups (mainland Australia, Bass Strait
