Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less
Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Aus ....Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Australia, the project will extend hydroclimatic records by several centuries, to identify the frequency and extent of extreme droughts across the continent. Outcomes are expected to provide appropriate context for evaluating and adapting to climate change, allowing climate modellers, agricultural producers and other industries to improve forecasts of likely change for risk management.Read moreRead less

Climate Change, Industrial Structure and the Knowledge Economy: Key Issues for an Effective Response on Greenhouse Gases. The objectives of this project are to undertake a major, long term study of the impact of global structural change on greenhouse gas emissions and on climate change, and to develop a detailed knowledge base concerning trade in embodied emissions. It is hoped that the knowledge generated will both inform global responses to this vital problem and contribute to the continuing d ....Climate Change, Industrial Structure and the Knowledge Economy: Key Issues for an Effective Response on Greenhouse Gases. The objectives of this project are to undertake a major, long term study of the impact of global structural change on greenhouse gas emissions and on climate change, and to develop a detailed knowledge base concerning trade in embodied emissions. It is hoped that the knowledge generated will both inform global responses to this vital problem and contribute to the continuing development of effective responses within Australia. The output - a book and many papers - will be directed in part to contribute to the IPCC's Fourth Assessment Report.Read moreRead less
Faunal responses to environmental change and isolation on an Australian land-bridge island. Establishing how faunas responded to past isolation and environmental changes offers great potential for predicting long-term impacts of habitat fragmentation. By combining novel methods we will track extinction rates, diet and body-size shifts on Kangaroo Island, the only known land-bridge island with a fossil record spanning the past 100,000 years.
Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how tem ....Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how temperature reverses chromosomal sex determination in dragon lizards. This could show how climatic extremes affect the biology of climate sensitive reptiles, and understand their vulnerability to climate change.Read moreRead less
