Hybridisation leading to lost sex: genomic and experimental insights. The project intends to apply advanced genomics to two classic Australian systems and quantitative genetics to one to address long-standing questions about why asexual reproduction is rare. It aims to test for rapid changes in genomes accompanying hybrid-origins of asexuals and whether this new diversity enables their ongoing evolution. The significance is that support for this hypothesis would challenge current theory for why ....Hybridisation leading to lost sex: genomic and experimental insights. The project intends to apply advanced genomics to two classic Australian systems and quantitative genetics to one to address long-standing questions about why asexual reproduction is rare. It aims to test for rapid changes in genomes accompanying hybrid-origins of asexuals and whether this new diversity enables their ongoing evolution. The significance is that support for this hypothesis would challenge current theory for why sex is so common. The expected outcome is to understand how variation is generated in natural populations with different ways of reproducing. Benefits would include significant contributions to global science, evolutionary training and potential applications in using hybridisation to manage threatened species or pests.Read moreRead less
A Varied Diet, Ageing, and the Evolution of Life Histories. This research aims to understand how nutritional environments affect lifespan and its evolution. The expected outcomes are improved knowledge around the biology of ageing including the identification of diet-responsive genes and biological pathways. These elements will comprise targets for future applied studies on ageing, metabolic dysfunction and personalised nutrition. This study will also inform as to how lifespans evolve. Because l ....A Varied Diet, Ageing, and the Evolution of Life Histories. This research aims to understand how nutritional environments affect lifespan and its evolution. The expected outcomes are improved knowledge around the biology of ageing including the identification of diet-responsive genes and biological pathways. These elements will comprise targets for future applied studies on ageing, metabolic dysfunction and personalised nutrition. This study will also inform as to how lifespans evolve. Because lifespan is a fundamental demographic trait, this knowledge will improve ability to predict how populations adapt to environmental change. Lastly, through methodological innovation this project will also provide new statistical tools for studying how treatments affect the risk of death age specifically.Read moreRead less
