Description :
This paper investigates within species patterns of genetic diversity and relatedness for Banksia hookeriana Meissn. (Proteaceae), a fire-killed shrub with a restricted geography range of only 80 x 30 km centered on the Eneabba Sandplain 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 the patterns of genetic diversity, and reveal the possible location of glacial refugia and postglacial migration pathways.
