Determining the relative roles of dispersal and vicariance in the assembly of the New Zealand fauna. New fossils from New Zealand's St Bathans Fauna (19-16 million years) will revolutionise our understanding of the shared biodiversity and evolutionary history of New Zealand and Australia through the first views of the origin and evolution of major Gondwanan groups including frogs, crocodiles, birds and bats on the now mostly-drowned continent Zealandia.
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less
Predicting genetic exchange between species under climate change. This project aims to resolve the factors that lead to the mixing of species’ gene pools, with a focus on whether climate change will increase such mixing, possibly leading to extinction by genetic swamping.
The significance is that the project would improve our understanding of speciation and species’ vulnerability to rapid climate change through genetic mixing; a largely overlooked process.
Key outcomes would be to generate new k ....Predicting genetic exchange between species under climate change. This project aims to resolve the factors that lead to the mixing of species’ gene pools, with a focus on whether climate change will increase such mixing, possibly leading to extinction by genetic swamping.
The significance is that the project would improve our understanding of speciation and species’ vulnerability to rapid climate change through genetic mixing; a largely overlooked process.
Key outcomes would be to generate new knowledge of a fundamental evolutionary process and extend the toolbox of biodiversity managers facing rapid environmental change.
The project would benefit Australia by highlighting our unique biodiversity and scientific capability, and by training early career researchers in advanced evolutionary biology.Read moreRead less
The evolution of generalism: why so many polyphagous fruit flies? This project aims to understand why flies that cause maggoty fruit have so frequently evolved the generalist feeding habitat. Insect herbivores make up 50 per cent of eukaryotic species on earth. Nearly all are host specialists, feeding on only one or very few plant species. In stark contrast, 40 per cent of tropical fruit flies are generalists, feeding across many plant families. This project aims to test specific hypotheses to e ....The evolution of generalism: why so many polyphagous fruit flies? This project aims to understand why flies that cause maggoty fruit have so frequently evolved the generalist feeding habitat. Insect herbivores make up 50 per cent of eukaryotic species on earth. Nearly all are host specialists, feeding on only one or very few plant species. In stark contrast, 40 per cent of tropical fruit flies are generalists, feeding across many plant families. This project aims to test specific hypotheses to explain the high frequency of generalism in Bactrocera. Outcomes will significantly advance understanding of the evolution of generalism, and so greatly advance herbivory theory. As Bactrocera are also globally significant horticultural pests, the project will provide under-pinning science for pest management.Read moreRead less
Recombination and the genomic landscape of speciation. This project aims to evaluate how genomes become different during the origin of species by utilising an innovative system where multiple replicates of the speciation process exist. This project expects to generate knowledge in the area of speciation genetics by exploring the effects of sex, migration and selection on the diversity of hundreds of genomes from an Australian wildflower. Expected outcomes of this project include a deeper underst ....Recombination and the genomic landscape of speciation. This project aims to evaluate how genomes become different during the origin of species by utilising an innovative system where multiple replicates of the speciation process exist. This project expects to generate knowledge in the area of speciation genetics by exploring the effects of sex, migration and selection on the diversity of hundreds of genomes from an Australian wildflower. Expected outcomes of this project include a deeper understanding of the maintenance of genetic diversity in natural populations, and development of a model organism for studying the genetics and ecology of speciation. This project should provide significant benefits including enhanced capacity in evolutionary genetics in Australia.Read moreRead less
Diversification and conservation of Australian frogs. Australia's 216 known species of frogs are exceptionally diverse, 98 per cent are found nowhere else in the world and many of them are in trouble. This project will test ideas concerning the tempo of Australian frog diversification, identify previously cryptic new species and provide information critical to the conservation of Australia's declining frogs.
