The genetic code of native plants are yet to be explored for DNA elements that promote resilience to climate change. These elements are now ripe for discovery due to recent advances in epigenomics allowing for rapid identification. This proposal aims to discover heat-associated elements in waxy bluebells, which inhabit Australia’s vulnerable high country. Expected outcomes include new insights on gene regulatory mechanisms in native plants; the generation of resources for genetic conservation, and catalysing further molecular research into Australian flora. This should provide significant benefits by revealing genome regulation in native plants, thereby improving the ability to predict the impacts of climate change.Read moreRead less
How does ecological disturbance shape the genetic diversity of natural populations? Environmental disturbances shape the dynamics of the world's ecosystems. However, we do not understand how they influence biodiversity at its most fundamental level, genetic diversity. This is important, because genetic diversity affects the fitness of individuals, the viability of populations and the adaptability of species. This project will study fire in the Australian environment to discover how disturbance a ....How does ecological disturbance shape the genetic diversity of natural populations? Environmental disturbances shape the dynamics of the world's ecosystems. However, we do not understand how they influence biodiversity at its most fundamental level, genetic diversity. This is important, because genetic diversity affects the fitness of individuals, the viability of populations and the adaptability of species. This project will study fire in the Australian environment to discover how disturbance affects genetic diversity. By integrating landscape genomics and computational modelling with long-term field studies, the research will significantly advance our understanding of how genetic diversity is distributed, and improve our ability to predict the responses of natural populations to changes in the frequency and severity of wildfire.Read moreRead less

Summary
Integrating ecology and evolution: how does sexual selection affect population fitness and extinction? Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationsh ....Integrating ecology and evolution: how does sexual selection affect population fitness and extinction? Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationship with sexual selection. It also proposes ambitious experimental evolution and quantitative genetic studies that will empirically measure the net effect of sexual selection on population fitness and extinction. This project aims to catalyse a change in the study of population fitness and address a conspicuous gap in contemporary evolutionary biology.Read moreRead less
The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentiall ....The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentially wide and novel significance. This project proposes to test the generality of our observations for other vertebrate-pollinated species, and to test the conservation and evolutionary consequences of reduced pollen dispersal caused by habitat fragmentation and declining pollinators for a pollination paradigm facilitating promiscuity.Read moreRead less
The Maintenance of Genetic Variation by Antagonistic Sexual Selection. The principle outcomes of my proposed research are fundamental knowledge, training of young scientists and the improvement of Australia's research capacity and profile. My research will have a major impact on two major branches of evolutionary biology that are seldom integrated - sexual selection and quantitative genetics. My research will enable me to establish myself as an independent researcher. Moreover, my collaborations ....The Maintenance of Genetic Variation by Antagonistic Sexual Selection.

In order to study such processes our collective experience strongly suggests and increasing need for geographic amalgamation of necessary and complementary molecular and biomedical techniques. We therefore request funding to establish a collaborative research laboratory in a novel research field - Evolutionary Immuno-Ecology- in which all vital aspects, from a mechanistic to an evolutionary level, can be studied at one research centre.Read moreRead less
