Sex chromosomes and speciation: chromosome inversion and the large Z-effect. This project aims to understand the divergence of species and the importance of two genomic features of often disproportionately large effect between young taxa – the sex chromosomes, and chromosome inversions. The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide sign ....Sex chromosomes and speciation: chromosome inversion and the large Z-effect.

The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide significant benefits such as enhancing Australia’s strength in the field of evolutionary biology.Read moreRead less
Explaining virus diversity. To prevent virus pandemics, it is necessary to understand how viruses evolve. This project aims to reveal the long-term trends, processes and drivers of RNA virus diversity and evolution. Through the metagenomic sequencing of the viromes of Australian animals that mark evolutionary innovations and transitions this project will reshape our knowledge of virus evolution and disease emergence. Expected outcomes will be a new understanding of how virus diversity is created ....Explaining virus diversity. To prevent virus pandemics, it is necessary to understand how viruses evolve. This project aims to reveal the long-term trends, processes and drivers of RNA virus diversity and evolution. Through the metagenomic sequencing of the viromes of Australian animals that mark evolutionary innovations and transitions this project will reshape our knowledge of virus evolution and disease emergence. Expected outcomes will be a new understanding of how virus diversity is created, how virus phenotypes have changed through time, how often viruses jump to new host species, and how major events in animal evolution have shaped virus diversity. Key benefits include new measures of the viral burden faced by Australia’s native animals and of ecosystem health.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
Mitonuclear incompatibility, speciation, and the Z sex chromosome. This project will characterise the interaction between the mitochondrial and nuclear genome in several species and its contribution to the divergence of species. This interaction is at the heart of energy transformation and storage in all animals and its importance to evolution is yet to be fully understood. The research will provide insight into speciation processes by focusing on recent divergence in Australian finch species. W ....Mitonuclear incompatibility, speciation, and the Z sex chromosome. This project will characterise the interaction between the mitochondrial and nuclear genome in several species and its contribution to the divergence of species. This interaction is at the heart of energy transformation and storage in all animals and its importance to evolution is yet to be fully understood. The research will provide insight into speciation processes by focusing on recent divergence in Australian finch species. We will integrate genomics, bioenergetics, and whole organismal performance in growth, mobility and reproduction by studying birds in the wild and the laboratory. An overarching aim is to unite data from genomics, phenotype and physiology to understand the forces underlying the evolution of species, and biodiversityRead 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
