The A. provides an overview and assessment of how geographers could potentially incorporate a genetic perspective into biogeographical research focused on past, present, and likely future species distributions. This effort is especially timely
as the lat 2 decades have seen monumental advances in the knowledge of how organismal molecular biology functions to create the physiological and reproductive characteristics of species and their respective populations. In addition, these genetic studies also
and extending them to eliminate problematic assumptions and to fit real-world geographical exigencies. Then, he illustrates how such models can be applied to research problems including hypothesis testing. Finally, the A. proposes an invasion rule based
of the midwestern coastal region of SW Australia. Six stands encompassing the whole of the extant geographic range of the species are analyzed to explore how Quaternary climate oscillations and the likely geomorphic consequence of dune mobilization might explain
