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. Yet we know little of the evolutionary mechanisms that have shaped their biodiversity.

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

Summary
Dispersal, diversity and survival: lessons from the fossil record. The ability of organisms to spread their genes may be key to their long-term survival. For example, birds survived the mass extinction of 65 million years ago, but their non-flying dinosaurian relatives did not. This project will use the fossil record to establish whether swimming or flying are key traits in long-term survival. This will be done by producing the first family tree for all extinct terrestrial vertebrates onto which ....Dispersal, diversity and survival: lessons from the fossil record. The ability of organisms to spread their genes may be key to their long-term survival. For example, birds survived the mass extinction of 65 million years ago, but their non-flying dinosaurian relatives did not. This project will use the fossil record to establish whether swimming or flying are key traits in long-term survival. This will be done by producing the first family tree for all extinct terrestrial vertebrates onto which geographic data will be mapped before a novel computational analysis shows how species moved between continents over the last 400 million years. The results may inform modern conservation issues, as changing climate means an organism's survival could be dependent on its ability to physically track shifting environments.Read moreRead less
