Many Australian birds show striking variation in plumage across their range. The Australian magpie is one of the best known. Its distribution covers most of mainland Australia and Tasmania, with male birds in the north having black backs and male birds in the south having white backs. In both the east and west, there are intermediate zones, where black-backed, white-backed and ‘hybrid’ birds occur. In this talk, I examine the possible causes of this distribution and the explanation for its apparently stable structure. I will describe a phylogeographic study across the entire distribution and a long-term ecological study in the eastern hybrid zone.

Her research has focused on using molecular approaches to address questions in ecology, biogeography and conservation. She and her students have published mostly in the areas of freshwater biodiversity and biogeography, as well as evolutionary and ecological studies of Australian birds, particularly the Australian Magpie.
