Sperm competition, sexual conflict, and gamete evolution in mice. The innovative experiments of this project will yield results that are at the forefront of research in evolutionary biology. This project will generate publications in high profile journals, and will foster collaborations between Australian and European researchers, creating a significant international impact and promoting excellence in Australian research. Since European settlement of Australia, sixty percent of the native rodent ....Sperm competition, sexual conflict, and gamete evolution in mice. The innovative experiments of this project will yield results that are at the forefront of research in evolutionary biology. This project will generate publications in high profile journals, and will foster collaborations between Australian and European researchers, creating a significant international impact and promoting excellence in Australian research. Since European settlement of Australia, sixty percent of the native rodent species have become extinct or are threatened with extinction. As there is a significant lack of research on the mating systems of Australian rodents, our investigations on a native mouse will generate information that will be extremely valuable to the national conservation efforts of threatened rodent species.Read moreRead less
Female roles during postcopulatory sexual selection. The project will evaluate the importance of postcopulatory sexual selection in the guppy, a polyandrous species of livebearing fish. The use of artificial insemination, which experimentally controls the relative contribution of sperm from competing males (as well as other confounding effects), will facilitate a powerful test of recent theoretical predictions in evolutionary biology. The project will enable me to distinguish between competing h ....Female roles during postcopulatory sexual selection. The project will evaluate the importance of postcopulatory sexual selection in the guppy, a polyandrous species of livebearing fish. The use of artificial insemination, which experimentally controls the relative contribution of sperm from competing males (as well as other confounding effects), will facilitate a powerful test of recent theoretical predictions in evolutionary biology. The project will enable me to distinguish between competing hypotheses for postcopulatory paternity bias following female multiple mating (sperm competition, cryptic female choice, genetic compatibility) and provide additional insights into the selective forces promoting the evolution of female promiscuity.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
The evolution of female multiple mating: genetic benefits and indirect genetic effects. This work will yield results at the forefront of evolutionary biology, thereby contributing to Australia's reputation as a country where excellent and original research is conducted. A greater understanding of the processes determining offspring viability, paternity success, and the acquisition of genetic quality will also benefit animal breeding and conservation biology. My research will work towards a bette ....The evolution of female multiple mating: genetic benefits and indirect genetic effects. This work will yield results at the forefront of evolutionary biology, thereby contributing to Australia's reputation as a country where excellent and original research is conducted. A greater understanding of the processes determining offspring viability, paternity success, and the acquisition of genetic quality will also benefit animal breeding and conservation biology. My research will work towards a better understanding of an ecologically important Australian native coastal species which supports commercial fisheries. Australian science will further benefit from the training of young scientists and from collaborations with international researchers that will promote excellence in Australian research.Read moreRead less

Identifying sperm quality or male viability is a crucial issue for livestock production. A greater understanding of the mechanisms of sperm competition and the benefits of multiple mating can also benefit conservation biology since these issues are being applied to undertake strategic plans for endangered species.Read moreRead less
