Uncovering the transgenerational dimension of ageing. Despite over a century of research on the biology of ageing, one intriguing aspect of ageing – the widely observed tendency for older parents to produce offspring with reduced lifespan and fitness – remains poorly understood. Such effects could be a major source of variation in individual fitness, could play a role in the evolution of ageing, and could impact human health. Building on recent discoveries by CI Bonduriansky’s research group and ....Uncovering the transgenerational dimension of ageing. Despite over a century of research on the biology of ageing, one intriguing aspect of ageing – the widely observed tendency for older parents to produce offspring with reduced lifespan and fitness – remains poorly understood. Such effects could be a major source of variation in individual fitness, could play a role in the evolution of ageing, and could impact human health. Building on recent discoveries by CI Bonduriansky’s research group and others, this project’s aims will address significant questions about the mechanisms mediating these effects, the roles of mothers vs. fathers, and the role of the ambient environment. This project will also contribute new theory on the evolutionary implications of such effects. Read moreRead less

Can sexual conflict contribute to a resolution of the paradox of sex? Despite over a century of research, it remains unclear why most animals can reproduce only via sex. An exciting new hypothesis proposes that sexual conflict can promote sexual reproduction and inhibit asexual strategies, suggesting a potential solution to this long-standing paradox. Building on my research expertise, and using a native Australian insect species in which the role of sexual conflict can be studied in natural pop ....Can sexual conflict contribute to a resolution of the paradox of sex? Despite over a century of research, it remains unclear why most animals can reproduce only via sex. An exciting new hypothesis proposes that sexual conflict can promote sexual reproduction and inhibit asexual strategies, suggesting a potential solution to this long-standing paradox. Building on my research expertise, and using a native Australian insect species in which the role of sexual conflict can be studied in natural populations, this ambitious project aims to test this hypothesis for the first time. This research will expand knowledge in the biological sciences by helping to answer one of the most challenging questions in evolutionary biology. This work will also contribute to efforts to monitor Australia's unique insect fauna.Read moreRead less

The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to unde ....The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to understand the genetic potential of organisms to adapt to anthropomorphic change in the environment connected with the resources industry. Our work, will bring new insight into the future management of environmental contamination, and the mitigation of adverse effects arising from resource extraction.Read moreRead less
