Unravelling Western Australia's Stormy Past - A Precisely-Dated Sediment Record of Cyclones over the past 7000 years. Australia has a vast coastline, much of which is vulnerable to cyclone impact. Clearly, historical human experience does not comprehend what the climate system is capable of in terms of epic storms. Our effort to understand the storm risks of the past is complicated by the limited length of the instrumental record which reaches back only 150 years of European settlement in tropic ....Unravelling Western Australia's Stormy Past - A Precisely-Dated Sediment Record of Cyclones over the past 7000 years. Australia has a vast coastline, much of which is vulnerable to cyclone impact. Clearly, historical human experience does not comprehend what the climate system is capable of in terms of epic storms. Our effort to understand the storm risks of the past is complicated by the limited length of the instrumental record which reaches back only 150 years of European settlement in tropical areas of Australia. This project will reconstruct the history of storms and cyclones using sedimentary signatures in Western Australia over the past 7000 years to assess storm and cyclone risks under changing future climates in a regional context.Read moreRead less

This project will provide tools essential for the effective management of Australia's ecosystems by delivering clear guidelines and practical methods that will substantially improve the modelling of future species distributions.
Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their p ....Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their protection; in aquaculture, selecting for productive fish will also increase aggression-related injuries. If not strongly linked, we may be able to select for high productivity and low aggression in fish, or high productivity and low metabolism, thus reducing feed costs in aquaculture associated with aggressive behaviour leading to injury and infection, and reduced growth at warmer temperatures.Read moreRead less
Molecular Archaeology: Carbon isotope analysis of amino acids as a means to investigate diets, physiology, metabolism and palaeoenvironment. The investigation of the bones of past societies and animals at the molecular level opens up a whole array of alternative data about palaeodiet and environment. Investigating the past in this way provides a unique perspective about how diet and health have changed in humans and about how animals and the environment have changed. When we understand the past ....Molecular Archaeology: Carbon isotope analysis of amino acids as a means to investigate diets, physiology, metabolism and palaeoenvironment. The investigation of the bones of past societies and animals at the molecular level opens up a whole array of alternative data about palaeodiet and environment. Investigating the past in this way provides a unique perspective about how diet and health have changed in humans and about how animals and the environment have changed. When we understand the past in this manner we can better understand current health issues linked to diet and how the environment and climate is changing.Read moreRead less

Changing Seas at Cellular to Cross-Ocean Scales. Australia relies greatly upon its rich natural environmental resources for goods, services and for economic growth (tourism, fisheries, and recreational industries). Climate change is one of the biggest threats to the natural marine environment. As the climate warms and oceans become more acidic, corals, the framework builders of reefs, experience unfavourable conditions. This project aims to better understand the processes by which ocean acidifi ....Changing Seas at Cellular to Cross-Ocean Scales. Australia relies greatly upon its rich natural environmental resources for goods, services and for economic growth (tourism, fisheries, and recreational industries). Climate change is one of the biggest threats to the natural marine environment. As the climate warms and oceans become more acidic, corals, the framework builders of reefs, experience unfavourable conditions. This project aims to better understand the processes by which ocean acidification and climate change affect corals, and to develop management tools for the mitigation of, and acclimation to, climate change. By so doing, this project will enable managers of Australia's Great Barrier Reef to better respond to the threatening challenges that climate change poses. Read moreRead less
Past and future effects of climate change on the carbon-water balance of plants. Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-clim ....Past and future effects of climate change on the carbon-water balance of plants. Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-climate feedbacks. It will determine the combined effects of elevated atmospheric CO2 and drought on the productivity of natural and agricultural landscapes, and provide the biophysical framework for developing the next generation of high-yielding, drought tolerant crop varieties for the rapidly approaching greenhouse world.Read moreRead less
