Summary
The role of epigenetic modifications in tiger snake adaptation. This project aims to investigate mechanisms underlying animal adaptation to future environmental change by examining the molecular basis for phenotypic plasticity in snakes. This project will specifically examine variation in genetic/epigenetic profiles and compare against important fitness traits, such as variable head size, bite force and swallowing performance to identify relationships between molecular change and physiology. Suc ....The role of epigenetic modifications in tiger snake adaptation. This project aims to investigate mechanisms underlying animal adaptation to future environmental change by examining the molecular basis for phenotypic plasticity in snakes. This project will specifically examine variation in genetic/epigenetic profiles and compare against important fitness traits, such as variable head size, bite force and swallowing performance to identify relationships between molecular change and physiology. Such research is a critical first step in improving our knowledge of the mechanisms whereby animal populations may adapt to environmental change, allowing us to facilitate such processes or concentrate conservation effort where species are unable to adapt via epigenetic modification.Read moreRead less
Using genetics to reconstruct the peopling and diversification of Sahul. A recent landmark study has revealed that people who first arrived on Sahul (the landmass connecting Australia with New Guinea) remained largely genetically isolated from subsequent migrations. However, there is still little known about the route(s) taken into Sahul, or how adaptation has shaped the enormous diversity now observed across Indigenous Australians and Papuans. This project aims to look at these issues by applyi ....Using genetics to reconstruct the peopling and diversification of Sahul. A recent landmark study has revealed that people who first arrived on Sahul (the landmass connecting Australia with New Guinea) remained largely genetically isolated from subsequent migrations. However, there is still little known about the route(s) taken into Sahul, or how adaptation has shaped the enormous diversity now observed across Indigenous Australians and Papuans. This project aims to look at these issues by applying phylogenetic and population genetic tools to the largest genetic dataset yet analysed from populations across Australia, New Guinea, and Island South East Asia. The outcomes of the project should reveal both the route(s) taken into Sahul and how adaptation has shaped the diversity now observed in descendants of the colonisation.Read moreRead less
Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
Adapting to a changing world: mothers as drivers of evolutionary change. This project will improve our understanding of how organisms will adapt to the unprecedented speed and magnitude of human-induced environmental change. By identifying how mothers modify their offspring to better match the prevailing environment, it will address the role of mothers in directing and accelerating adaptation in our changing world.
