Evaluating the adaptive potential of organisms to respond to environmental change. 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 restricte ....Evaluating the adaptive potential of organisms to respond to environmental change. 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 ancient DNA to understand Australia's past and manage its future. The aim of this program is to establish an ancient DNA research centre for Australia, and use long-term natural records to investigate the genetic responses of animals, plants, and micro-organisms to environmental change.

This research will quantify the contribution to Australian regional climate change due to greenhouse gases, which will assist policymakers in reaching decisions about policies on emission reductions or adaptation to greenhouse climate change. Improved estimates of uncertainties in future regional climate changes due to increasing greenhouse gases will allow better quantification of their likely impacts, estimation of the costs or maximising any benefits from regional climate changes. Through collaboration with the Bureau of Meteorology and CSIRO, this research enhances Australia's capabilities in diagnostic analysis of climate variability and change, and aids the development and evaluation of new Australian climate models.

Genesis of Australian Climate Extremes in the Southern Hemisphere Extratropical Ocean-Atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental s ....Genesis of Australian Climate Extremes in the Southern Hemisphere Extratropical Ocean-Atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustainability. I propose to launch a major new initiative in extratropical climate analysis. This work will have significant benefits for the many sectors of society reliant on interseasonal-interannual climate prediction. Prominent examples include agriculture, energy, freshwater supply, bushfire control, air quality, health, and tourism.Read moreRead less
The time scales of geochemical cycles and earth processes. Precise information on timescales and rates of change is fundamental to understanding natural processes and the development and testing of quantitative physical models in the Earth Sciences. Uranium decay-series isotope studies are revolutionising this field by providing time information in the range 10^2-10^4 years, similar to that of many important Earth processes.

Precise information on timescales and rates of change is fundamental to understanding natural processes and the development and testing of quantitative physical models in the Earth Sciences. Uranium decay-series isotope studies are revolutionising this field by providing time information in the range 10^2-10^4 years, similar to that of many important Earth processes. This project will establish a world-class Australian Uranium-series research group to investigate the processes of magma formation and transport, continental growth, rates of erosion and recycling. These methodologies can also constrain processes governing water flow and reservoirs, mineral resources, volcanic eruptions, carbon cycles and other environmentally important processes/systems/cycles.Read moreRead less
Complexity in climate impact assessment: a methodology to address extremes. It is something of a truism that the events and states of the changing environment that affect society tend to fall in the extremes. My goal is to develop a model-based methodology to characterize the extremes that are not usually predicted by climate models. Key extremes of importance to stakeholders in Australia and around the world include coastal flooding and fire. These events, in the context of regional climate var ....Complexity in climate impact assessment: a methodology to address extremes. It is something of a truism that the events and states of the changing environment that affect society tend to fall in the extremes. My goal is to develop a model-based methodology to characterize the extremes that are not usually predicted by climate models. Key extremes of importance to stakeholders in Australia and around the world include coastal flooding and fire. These events, in the context of regional climate variation, will act as test cases for the methodology. From this work, the likelihood of policy-relevant events in the future can be evaluated, with a robust assessment of the uncertainty.Read moreRead less

Climate change poses a wide range of challenges to Australia's agricultural sector and for the management of natural ecosystems. These challenges are recognised in the National Research Priorities 1, An Environmentally Sustainable Australia, and 4, Safeguarding Australia. The potential economic costs of climate change to vital national assets such as the Murray-Darling Basin and the Great Barrier Reef, amount to billions of dollars per year, and ecological costs are even more significant. Uncertainty about the rate at which climate change will take place and about effects in different regions is central to the problem. This project will explore adaptive management strategies that promote resilience in the face of uncertainty.
