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.

Metapopulation and habitat quality: towards an integrated approach to the conservation of an endangered grassland lizard. Our research will provide the basis upon which the grassland earless dragon can be removed from its endangered status and provide a template for the future science based management of other endangered species. Australia will gain through this project by reducing its risk of losing yet another species through inappropriate management.
The evolution and maintenance of specificity, mutualism and diversity in plant-soil microbe interactions. This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration prac ....The evolution and maintenance of specificity, mutualism and diversity in plant-soil microbe interactions. This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration practices. Furthermore, it will see the continued development of the Acacia-rhizobia system as a world-class model for exploring interactions between perennial legumes and microbial symbionts. The research also investigates the adaptability and potential for rapid evolution of critical elements of the soil microflora to environmental change.Read moreRead less
A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertis ....A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertise developed will contribute directly to the conservation of endangered Australian orchids, and will take into account the risks of climate change. The project will contribute to the priority research goals of sustainable use of Australia's biodiversity as well as responding to climate change and variability. The project will also provide high quality, cross-disciplinary training.Read moreRead less
Diversity out of a hybrid zone: the interplay of reinforcement and sexual selection in the formation of new species. How are there so many different species? Understanding how new species arise is a fundamental question because it explains current biodiversity and reveals the processes that will continue to give rise to new species in the future. An integral part of any animal species is who they choose to mate with, but how mate choice evolves to create new species remains poorly understood. He ....Diversity out of a hybrid zone: the interplay of reinforcement and sexual selection in the formation of new species. How are there so many different species? Understanding how new species arise is a fundamental question because it explains current biodiversity and reveals the processes that will continue to give rise to new species in the future. An integral part of any animal species is who they choose to mate with, but how mate choice evolves to create new species remains poorly understood. Here I will be studying the processes that affect the evolution of mate choice in an Australian rainforest frog hybrid zone. This system is uniquely suitable for providing internationally important insights into the evolutionary processes that form new species.Read moreRead less
Life history responses to habitat heterogeneity and implications for conservation. This exciting new research project will provide a novel understanding of how animals respond and adapt to environmental variation. This will fill a critical gap between ecological theory and real-world populations and initiate a major shift in how we view the relationship between environments and the species that inhabit them. Natural resource use practices like forestry are rarely considered compatible with biodi ....Life history responses to habitat heterogeneity and implications for conservation. This exciting new research project will provide a novel understanding of how animals respond and adapt to environmental variation. This will fill a critical gap between ecological theory and real-world populations and initiate a major shift in how we view the relationship between environments and the species that inhabit them. Natural resource use practices like forestry are rarely considered compatible with biodiversity conservation. This research will provide on-the-ground management recommendations to integrate such land uses with conservation, thereby providing both economic and conservation benefits to the Australian community.Read moreRead less
