Uncovering the evolutionary history of Australasian marsupials: combining molecular phylogenetics and ecological inference. Marsupials are symbolic of the uniqueness of Australia's biological systems and there is widespread public interest in their natural history.

Marsupials are symbolic of the uniqueness of Australia's biological systems and there is widespread public interest in their natural history. Yet we know little of the evolutionary mechanisms that have shaped their biodiversity. This is a critical problem when considered in the context of Australian marsupials having suffered the highest extinction rate of any continental mammal fauna over the past 200 years. This project will make a major contribution to understanding the origins, timescale and ecological nature of Australasian marsupial evolution. In doing so, it will inform conservation strategy, promote Australasian marsupials as a model system for studying faunal coevolution and develop widely applicable bioinformatic tools.Read moreRead less
Generalised methods for testing extinction dynamics across geological, near and modern time scales. The record of extinctions over deep time is patchy and incomplete, yet we must use it to determine how major changes in past environments have shaped life on Earth today. The project will develop cutting-edge mathematical tools to determine the patterns of extinctions and speciation over geological time to help predict our uncertain environmental future.
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.
