Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosys ....Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosystems will allow us to make better decisions when trying to establish sustainable and 'natural' mainland and island sanctuaries. Ancient DNA is well preserved in some dry environments; this project will assess DNA preservation from sites all across Australia and use the DNA sequences to discover information about extinct animals and how past climate changes effected the native biota.Read moreRead less
Inbreeding: what are the reproductive costs and how are they avoided? Inbreeding in animal populations will undoubtedly become more prevalent in the face of increased habitat fragmentation brought on by human activities and climate change. By increasing our understanding of how inbreeding influences reproductive traits, my research will be directly applicable to conservation programs, specifically by providing insights into how Australia's rich biodiversity will respond to climate change and var ....Inbreeding: what are the reproductive costs and how are they avoided? Inbreeding in animal populations will undoubtedly become more prevalent in the face of increased habitat fragmentation brought on by human activities and climate change. By increasing our understanding of how inbreeding influences reproductive traits, my research will be directly applicable to conservation programs, specifically by providing insights into how Australia's rich biodiversity will respond to climate change and variability. This project also addresses critical issues in evolutionary biology, thereby contributing towards Australia's reputation as a world leader in this field. Australian science will further benefit through international collaborations and from the training of young scientists.Read moreRead less
Effects of ants and ant-mediated dispersal on speciation rates, biogeography and diversity of angiosperms. This work seeks to improve our general understanding of longstanding questions in ecology in evolution, namely what are the processes that have allowed some groups to become diverse and others not, why does dispersal mode vary with geography, and how do speciation and extinction vary across space, time and taxon? In answering these questions, we will address some of the most fundamental que ....Effects of ants and ant-mediated dispersal on speciation rates, biogeography and diversity of angiosperms. This work seeks to improve our general understanding of longstanding questions in ecology in evolution, namely what are the processes that have allowed some groups to become diverse and others not, why does dispersal mode vary with geography, and how do speciation and extinction vary across space, time and taxon? In answering these questions, we will address some of the most fundamental questions in conservation, including what are the factors that make species geographically rare, which species are most at risk for climate change, and what are the factors that have led habitats like the Kwongan Heath and Fynbos to be so exceptionally biodiverse.Read moreRead less
Conservation genetics of humpback whales off Western Australia: Implications for the management of the Antarctic Group IV population. We will define the geographic structuring and gene flow of humpback whales comprising Antarctic Area Group IV, and which migrate off the coast of Western Australian. With this information we will develop guidelines for commonwealth, state, industry, and non-government organisations, for conserving and managing discrete (genetic) populations of humpback whales off ....Conservation genetics of humpback whales off Western Australia: Implications for the management of the Antarctic Group IV population. We will define the geographic structuring and gene flow of humpback whales comprising Antarctic Area Group IV, and which migrate off the coast of Western Australian. With this information we will develop guidelines for commonwealth, state, industry, and non-government organisations, for conserving and managing discrete (genetic) populations of humpback whales off Western Australia. We can then manage these cetaceans at the appropriate geographic scale, and assign conservation priority in relation to population genetic structure gained from this study.Read moreRead less
