Has Twentieth Century warming changed southeastern Australia's fire regimes? This project will reconstruct extreme fire seasons and fire events for the past 500 years in three temperate regions of southeastern Australia. This baseline information will extend our historic records of fire, quantify the controls on fire in our landscapes and place recent catastrophic fire events in historical context.
Past climate and environmental impacts on Great Barrier Reef paleoecology. This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death event ....Past climate and environmental impacts on Great Barrier Reef paleoecology. This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death events to establish which environmental stressors and paleoclimate variations are most critical for reef health. The outcomes will better constrain long term coral reef dynamics and provide significant benefits to those who manage reefs globally, since the Great Barrier Reef covers the full range of reef environments.Read moreRead less

Summary
Tracking the response of the Australian climate to abrupt climate change. This project will use cutting-edge climate proxy analyses to reconstruct the response of the Australian climate system to global climate change over the last 2,000 years. The results will provide significant insight in to how future global climate change will impact on social, biological and physical systems in Australia.
Mesozoic Austral Biodiversity: Research and Regional Museum Applications. The impact of environmental alteration on Australia’s biodiversity has poorly understood long-term effects. This project examines the controversial biogeography and evolution of Australia’s biodiversity during the Age of Dinosaurs (mid-Cretaceous ~100 MYA) and their adaptational responses to climatic change. Fossils readily capture the public imagination and thus help promote complex scientific concepts in the global media ....Mesozoic Austral Biodiversity: Research and Regional Museum Applications. The impact of environmental alteration on Australia’s biodiversity has poorly understood long-term effects. This project examines the controversial biogeography and evolution of Australia’s biodiversity during the Age of Dinosaurs (mid-Cretaceous ~100 MYA) and their adaptational responses to climatic change. Fossils readily capture the public imagination and thus help promote complex scientific concepts in the global media. This project raises awareness about sustainable use of non-renewable fossil resources through public education and ecotourism fieldwork programs; these will help generate local interest and thus protection of sensitive fossil localities by highlighting them as lucrative tourism assets for regional communities.Read moreRead less
Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they ....Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they do so limits attempts at accurate predictive climate modelling. This project will test conceptual models of SWW dynamics and provide essential boundary conditions for predictive climate models. The project intends to simultaneously build and support a research capacity and global network, and advance Australia’s knowledge and contribution in the area of global climate dynamics.Read moreRead less
Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this ....Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this project will investigate how body size of marine species and communities evolved in response to the mass extinction and rapid global warming. It is expected that the project findings will help better understand the links between global warming, anoxia, hypercapnia, euxinia, ocean acidification, and species adaptation and evolution.Read moreRead less
The last glaciation maximum climate conundrum and environmental responses of the Australian continent to altered climate states. This project will show how climate systems in south east Australia responded to large scale global change the last time this happened, which was about 21,000 years ago. By determining the climate response in Australia to this change, this project will help predict future response in rainfall and temperature to human-induced and natural climate change.

Summary
Stable isotope analysis of environmental and physiological samples. Mass spectrometers capable of isotope analysis are essential tools for the earth and environmental sciences, physiology and palaeoecology. This project will provide mass spectrometers for both laboratory and field conditions which will ensure Australia remains at the forefront of international research, attract collaborations and lead to outcomes of global significance.
Quantifying the effects of western colonisation on Great Barrier Reef molluscan communities. Dead shells provide a record of the pre-colonisation Great Barrier Reef (GBR) ecosystem. Using this record this research will determine what the GBR looked like before James Cook and the first fleet arrived in Australia. This study will also sample living molluscs to quantify the current state of these communities. Together these data will provide environment managers and stakeholders with the first quan ....Quantifying the effects of western colonisation on Great Barrier Reef molluscan communities. Dead shells provide a record of the pre-colonisation Great Barrier Reef (GBR) ecosystem. Using this record this research will determine what the GBR looked like before James Cook and the first fleet arrived in Australia. This study will also sample living molluscs to quantify the current state of these communities. Together these data will provide environment managers and stakeholders with the first quantitative estimates of human impacts on this world heritage ecosystem. This project will address the questions: Do protected areas return to a pre-colonial state or do they represent another non-natural state? What type of management scheme results in communities most similar to the pre-colonial state?Read moreRead less
