Genetic approaches are a powerful tool to detect previously overlooked biodiversity. My research focuses on genetic structure in marine animals and how it was shaped both by contemporary and historical environmental conditions. I have mostly worked on marine invertebrates and on fishes in southern Africa, a very exciting region in which to conduct phylogeographic research because this is where the biodiversity of the Atlantic Ocean mixes with that of the Indian Ocean (please see publication #3 below). Most of the “species” I have studied turned out to be species complexes, and the ranges of these are typically limited by environmental discontinuities. While based at Flinders, I will develop new tools to study how such “cryptic” species are adapted to their environment and to develop microsatellite libraries to uncover genetic patterns that have evolved very recently. The temperate marine fauna of southern and eastern Australian is very similar to that of southern Africa, but the oceanography and coastal topography of the two regions differs considerably. My long-term goal is to contrast what factors led to the evolution of new species in temperate Australia and southern Africa.
– Comparative phylogeography of temperate Australian coastal invertebrates
– Evolutionary history of the crab genera Hymenosoma (southern Africa) and Amarinus (Australia)
– Sex-specific genetic structure in marine mussels
– Population genetics of Antarctic terns
– Stock structure in commercially exploited southern African seabreams
