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
A modelling analysis of the implications of biogenic feedbacks on environment for the adaptation of ecosystems. The sustainable management of Australia's living resources depends critically on a deep understanding of the fundamental properties of ecosystems. These properties will determine the response of an ecosystem to perturbation. Anthropogenic perturbation of ecosystems, whether instantiated by living resource harvesting, habitat destruction, species invasions, pollution or climate change, ....A modelling analysis of the implications of biogenic feedbacks on environment for the adaptation of ecosystems. The sustainable management of Australia's living resources depends critically on a deep understanding of the fundamental properties of ecosystems. These properties will determine the response of an ecosystem to perturbation. Anthropogenic perturbation of ecosystems, whether instantiated by living resource harvesting, habitat destruction, species invasions, pollution or climate change, is the greatest current threat to Australia's biodiversity and hence the continued functioning of the systems that we rely on for maintaining our environment in a habitable state and for providing economic benefit. This research will attempt to discover some of these properties, and assess their implications for the sustainably management of our environment.Read moreRead less
Wild eco-evolutionary dynamics: the decline of an iconic Australian bird. This project aims to dissect the ecological and evolutionary processes causing a decline in an iconic Australian bird species. Studies that can properly test explanations for declines in wild populations are rare. This project aims to test how environmental and genetic processes shape individual traits, how these traits determine fitness and how changes in individual fitness affect population dynamics. The project expects ....Wild eco-evolutionary dynamics: the decline of an iconic Australian bird. This project aims to dissect the ecological and evolutionary processes causing a decline in an iconic Australian bird species. Studies that can properly test explanations for declines in wild populations are rare. This project aims to test how environmental and genetic processes shape individual traits, how these traits determine fitness and how changes in individual fitness affect population dynamics. The project expects to provide essential information for the improved management of Australian bird populations, and for understanding the effects of environmental change on natural systems globally.Read moreRead less
Diversity of Salinispora actinobacteria producing pharmaceutically relevant natural products from Australian marine sponges. By investigating the distribution of marine microbial resources relevant to drug discovery, we will directly contribute to ARC's Research Priority I - An Environmentally Sustainable Australia Priority Goal and the Priority Goal 'Sustainable use of Australia's biodiversity'. We will determine sources of marine bacteria and their genes useful for discovery of new natural pro ....Diversity of Salinispora actinobacteria producing pharmaceutically relevant natural products from Australian marine sponges. By investigating the distribution of marine microbial resources relevant to drug discovery, we will directly contribute to ARC's Research Priority I - An Environmentally Sustainable Australia Priority Goal and the Priority Goal 'Sustainable use of Australia's biodiversity'. We will determine sources of marine bacteria and their genes useful for discovery of new natural products for treatment of human diseases. We will do this by understanding where new strains of Salinispora bacteria may be isolated and how they are distributed in association with Australian marine sponge fauna, and by determining the distribution and chemical and genetic diversity of novel marine Salinispora bacteria.Read moreRead less
A molecular/morphological view of animal evolution based on marsupials. This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalo ....A molecular/morphological view of animal evolution based on marsupials. This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalogue of the evolving marsupial skeleton, which could provide a detailed and publicly accessible narrative of the evolutionary past and future adaptability of Australian marsupials. The proposed development of methods to quantify the effect of past and present biodiversity crises (e.g. environmental change) is expected to inform longer-term conservation planning.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.
