Transitions between modes of sex-determination in a changing world. Sex-determination controls the largest variation within animals—the division into males and females. While the different systems of sex-determination—involving genetic or environmental control—are fairly well understood, transitions between these systems remain enigmatic in evolutionary biology. This project aims to address this gap by revealing the molecular change required to transition between systems, using one of only two k ....Transitions between modes of sex-determination in a changing world. Sex-determination controls the largest variation within animals—the division into males and females. While the different systems of sex-determination—involving genetic or environmental control—are fairly well understood, transitions between these systems remain enigmatic in evolutionary biology. This project aims to address this gap by revealing the molecular change required to transition between systems, using one of only two known lizard species exhibiting both genetic and temperature control of sex. This knowledge will have important implications for species conservation, facilitating predictions of highly biased sex ratios under climate change, plus potential commercial applications for species where production of one sex is favoured.Read moreRead less

Summary
Pioneering alpine epigenomics to discover adaptive genetic elements. 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 n ....Pioneering alpine epigenomics to discover adaptive genetic elements. 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

Summary
Adaptive evolution and its demographic consequences today. This project aims to provide the first test of whether the rate of adaptative genetic evolution has changed in the recent decades, to quantify how much recent genetic evolution helps animal populations survive, and to increase the ability to study on-going genetic evolution in Australian wildlife. The project is of major significance as many species are currently threatened, or invading, due to rapid environmental changes, in particular ....Adaptive evolution and its demographic consequences today. This project aims to provide the first test of whether the rate of adaptative genetic evolution has changed in the recent decades, to quantify how much recent genetic evolution helps animal populations survive, and to increase the ability to study on-going genetic evolution in Australian wildlife. The project is of major significance as many species are currently threatened, or invading, due to rapid environmental changes, in particular climate change. The anticipated outcome of the project is to deliver new methods, establish a network of international and national collaborators and improve the ability to measure and to forecast how Australian animals adapt to rapidly changing environments.Read moreRead less
