Summary
The drivers of genome evolution and diversification in marsupials. This project aims to investigate the impact of the four basic forces of evolution, mutation, selection, neutral drift, and gene flow, on the genome. Genome-scale data have a signature of these forces and extracting it would greatly improve the quality of evolutionary models fit to the data, but the framework to identify the evolutionary forces has not been developed. This project will develop tests for assessing the impact of the ....The drivers of genome evolution and diversification in marsupials. This project aims to investigate the impact of the four basic forces of evolution, mutation, selection, neutral drift, and gene flow, on the genome. Genome-scale data have a signature of these forces and extracting it would greatly improve the quality of evolutionary models fit to the data, but the framework to identify the evolutionary forces has not been developed. This project will develop tests for assessing the impact of the primary evolutionary forces on the genome, and test these methods using simulations. The new framework of genomic analysis will be disseminated through an intuitive software package, and will be used to estimate with unprecedented confidence the history of diversification and genome evolution of marsupials.Read moreRead less

Summary
Biodiversity, biogeography and molecular evolution on tropical reefs. This project aims to discover how evolutionary processes, biogeography and molecular change drive biodiversity patterns. Coral reefs support over 800,000 plant and animal species on <0.1% of the ocean. This project will examine how this biodiversity was formed by generating genomic data for reef building corals and reef associated fishes to reconstruct their evolutionary history. It will compare models of speciation, extinctio ....Biodiversity, biogeography and molecular evolution on tropical reefs. This project aims to discover how evolutionary processes, biogeography and molecular change drive biodiversity patterns. Coral reefs support over 800,000 plant and animal species on <0.1% of the ocean. This project will examine how this biodiversity was formed by generating genomic data for reef building corals and reef associated fishes to reconstruct their evolutionary history. It will compare models of speciation, extinction and range change among regions to determine how those processes contribute to the formation of biodiversity gradients and regional assemblage differences. The project expects that better understanding of evolutionary dynamics will inform conservation priorities.Read moreRead less
Origins of a biodiversity hotspot flora: diversification of the Australian Proteaceae. Why does Australia's only biodiversity hotspot, with nearly 3000 endemic plant species, occur in an area with poor soils and low rainfall? This project will analyse DNA sequences from over 1000 plant species of the Australian Proteaceae, many found only in this hotspot, to help us understand the evolutionary and ecological origins of this iconic flora.
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
