The program utilizes technological advances to develop a gene inventory for climatic change adaptation, using, as model system, the vinegar fly from divergent climates along eastern Australia. The inventory will result in new methods for monitoring climatic change impact on populations, and for testing adaptive potential of organisms from threatened habitats. A key hypothesis is that these organisms have restricted genetic options to counter environmental change, increasing extinction risk. The program investigates genetic adaptation to pollutants in midges, a key group for monitoring water health. By assessing evolutionary potential and DNA species markers, biological signatures of aquatic pollutants should result.Read moreRead less
Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selec ....Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selection and drift. It will create a novel temporal dataset of genomic adaptation and evolution, and will generate critical data for studies of evolutionary processes such as extinctions, speciation and conservation biology and management.Read moreRead less
Genetics of species differentiation and hybridisation in Eucalyptus. Eucalypts are an icon of Australia and of great economic and ecological significance. This project will use genomic technologies to provide novel insights into the evolutionary processes that shape diversity in this genus. This will contribute to the development of better conservation and management practices for this valuable genetic resource.
Understanding “reinforcement”, an evolutionary process that can lead to the origin of new species and generate species diversity. Understanding how species are formed is of broad significance. National benefit will come from internationally competitive research and collaborations with leading international researchers. Benefits will also come under the ARC Priority Goals of 'An Environmentally Sustainable Australia' as I will (i) provide genetic data that will be invaluable for the conservation ....Understanding “reinforcement”, an evolutionary process that can lead to the origin of new species and generate species diversity. Understanding how species are formed is of broad significance. National benefit will come from internationally competitive research and collaborations with leading international researchers. Benefits will also come under the ARC Priority Goals of 'An Environmentally Sustainable Australia' as I will (i) provide genetic data that will be invaluable for the conservation of a highly threatened species, (ii) determine the importance of contact zones for generating new species and maintaining the evolutionary potential of regions, and (iii) address the role of climate change in shaping diversity over recent evolutionary time, an understanding of which is essential for predicting the impact of future change.

This project aims to determine the effects of changing environments on wild animal populations across Australia. By combining recent advances in genomic technology with a consortium of fourteen long-term studies of mammals, birds and reptiles, it aims to quantify the genetic basis of life-history variation and the potential for evolutionary adaptation in the wild. The project will generate a comprehensive understanding of the genetic consequences of environmental change, population decline, inbreeding and disease in natural environments. The expected benefits include a coordinated network for long-term wild animal studies in Australia, advanced quantitative skills training, and knowledge transfer for wildlife management and conservation.Read moreRead less
The genetic basis of differentiation: Towards a predictive understanding of evolution in the wild. Given that Australia cannot escape the effects of, among others, climate change and habitat deterioration, the question of how this is going to impact Australia's unique flora and fauna is an important one. Since extinction is the final consequence of the inability to adapt with sufficient speed to changing environmental conditions, this raises the issue of how well we understand the processes unde ....The genetic basis of differentiation: Towards a predictive understanding of evolution in the wild. Given that Australia cannot escape the effects of, among others, climate change and habitat deterioration, the question of how this is going to impact Australia's unique flora and fauna is an important one. Since extinction is the final consequence of the inability to adapt with sufficient speed to changing environmental conditions, this raises the issue of how well we understand the processes underlying evolutionary adaptation. This project will provide insight into the process of population divergence and the role of genetics therein, and will enhance our understanding of the effects of environmental change, habitat fragmentation and population bottlenecks on population viability and Australia's biodiversity in general.

Climate change threatens biodiversity in alpine areas of Australia. This project seeks to predict how plants, soils and small animals will respond to warming and the associated increased risk of bushfire. Our project uses chambers placed out in the field to simulate warming conditions, and measures plant growth and development, and small animal community structure within the chambers. We also assess the effects of climate change on soil processes. The information is used to evaluate the ability of alpine plants and animals to deal with climate change and to identify ways managers can help maintain biodiversity in this fragile ecosystem.

This project aims to predict the future of coral reefs in the rapidly changing climate of the Anthropocene by integrating state-of-the-art population genomics with evolutionary and ecological modelling. The project expects to describe pathways of genetic and non-genetic adaptation; and the strength and direction of connectivity of warm vs cold adapted coral populations - united in an eco-evolutionary framework. Expected outcomes address critical gaps in data and methodology that currently hinder our ability to reliably model the evolutionary and ecological dynamics of one of the most biologically diverse, socially and economically valuable and climatically vulnerable ecosystems of our planet, contributing to their science-based management.

The project will will enable Australia to take the lead in the global analysis of oligotrophy, highlighting the reputation Australian scientists have in scientific programs of global significance. As Australia is surrounded by some of the most oligotrophic waters in the world, we have access to an enormous natural resource suitable for the isolation of oligotrophs. Realising the potential of oligotrophs may therefore provide an invaluable source of compounds, enzymes and molecules for biotechnology and industry. Understanding microbial oligotrophy will also ensure we protect our $50 billion dollar tourism industry by remaining abreast of factors which influence the marine environment and directly impact on all coastal activities.Read moreRead less
