The genetic basis of differentiation: Towards a predictive understanding of evolution in the wild. Given that Australia cannot escape the effects of, among others, climate change and habitat deterioration, the question of how this is going to impact Australia's unique flora and fauna is an important one. Since extinction is the final consequence of the inability to adapt with sufficient speed to changing environmental conditions, this raises the issue of how well we understand the processes unde ....The genetic basis of differentiation: Towards a predictive understanding of evolution in the wild. Given that Australia cannot escape the effects of, among others, climate change and habitat deterioration, the question of how this is going to impact Australia's unique flora and fauna is an important one. Since extinction is the final consequence of the inability to adapt with sufficient speed to changing environmental conditions, this raises the issue of how well we understand the processes underlying evolutionary adaptation. This project will provide insight into the process of population divergence and the role of genetics therein, and will enhance our understanding of the effects of environmental change, habitat fragmentation and population bottlenecks on population viability and Australia's biodiversity in general.

Understanding “reinforcement”, an evolutionary process that can lead to the origin of new species and generate species diversity. Understanding how species are formed is of broad significance. National benefit will come from internationally competitive research and collaborations with leading international researchers. Benefits will also come under the ARC Priority Goals of 'An Environmentally Sustainable Australia' as I will (i) provide genetic data that will be invaluable for the conservation ....Understanding “reinforcement”, an evolutionary process that can lead to the origin of new species and generate species diversity. Understanding how species are formed is of broad significance. National benefit will come from internationally competitive research and collaborations with leading international researchers. Benefits will also come under the ARC Priority Goals of 'An Environmentally Sustainable Australia' as I will (i) provide genetic data that will be invaluable for the conservation of a highly threatened species, (ii) determine the importance of contact zones for generating new species and maintaining the evolutionary potential of regions, and (iii) address the role of climate change in shaping diversity over recent evolutionary time, an understanding of which is essential for predicting the impact of future change.

Evaluating the adaptive potential of organisms to respond to environmental change. The program utilizes technological advances to develop a gene inventory for climatic change adaptation, using, as model system, the vinegar fly from divergent climates along eastern Australia. The inventory will result in new methods for monitoring climatic change impact on populations, and for testing adaptive potential of organisms from threatened habitats. A key hypothesis is that these organisms have restricte ....Evaluating the adaptive potential of organisms to respond to environmental change. The program utilizes technological advances to develop a gene inventory for climatic change adaptation, using, as model system, the vinegar fly from divergent climates along eastern Australia. The inventory will result in new methods for monitoring climatic change impact on populations, and for testing adaptive potential of organisms from threatened habitats. A key hypothesis is that these organisms have restricted genetic options to counter environmental change, increasing extinction risk. The program investigates genetic adaptation to pollutants in midges, a key group for monitoring water health. By assessing evolutionary potential and DNA species markers, biological signatures of aquatic pollutants should result.Read moreRead less
