Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that clim ....Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that climate change was to blame. This study will refine our knowledge of the timing and causes of these extinctions in southern Australia by assessing how communities responded to climate change in the lead-up to human arrival. It will provide vital information for managing the conservation of many modern species and guide us in limiting future losses.Read moreRead less
Managing fire and ecology in northern Australia. This project aims to understand how fire affects the northern Australian savannah. European arrival changed how fire was used in Australia. This project will use ecology, palaeoecology and model development to develop pre-European ecological baselines in northern Australia and to reconstruct changes in plant cover in response to changes in fire regime. By understanding the effect of fire, the project will support the effective maintenance of the e ....Managing fire and ecology in northern Australia.

Traditional Owner-led restoration of urban billabongs. This Indigenous scientist led project aims to investigate the past and present fire, flooding and vegetation dynamics of urban billabongs through paleoenvironmental assays (sediment cores) and field surveys of vegetation, faunal and water quality responses to cultural burns and floods. In partnership with Melbourne Water and Traditional Owners, this innovative project intends to develop and combine historical and contemporary ecological and ....Traditional Owner-led restoration of urban billabongs. This Indigenous scientist led project aims to investigate the past and present fire, flooding and vegetation dynamics of urban billabongs through paleoenvironmental assays (sediment cores) and field surveys of vegetation, faunal and water quality responses to cultural burns and floods. In partnership with Melbourne Water and Traditional Owners, this innovative project intends to develop and combine historical and contemporary ecological and Indigenous peoples’ knowledge and apply it to better manage culturally and ecologically significant billabongs in one of Australia’s largest cities. This project expects to provide a template for effective Traditional Owner-led restoration and management of our threatened urban wetlands.Read moreRead less
Changing perspective: using fish ear bones to counteract the shifting baseline syndrome. Chemical tracers in fish ear bones from 5,500 years ago through to modern times will provide information on changes in fish ecology over centuries and identify why fish populations have declined. Outcomes will provide knowledge of how fish populations would react to altered fishing pressure and restoration of environments.

How has bushfire activity varied around the Southern Hemisphere over the last 10,000 years? We will determine the relative contribution of climate and human ignitions in driving bushfire activity around the Southern Hemisphere over the last 10,000 years. Such knowledge is crucial for ecologically sustainable fire management, resolving debates about past Aboriginal environmental impacts and understanding the risk posed by climate change.
The Devonian Gogo Fauna: Diversity, Palaeoecology and Global Significance. The late Devonian Gogo Formation (380 million years old) is undoubtedly one of the richest and best-preserved assemblages of fossil fishes and invertebrates from this age anywhere on Earth. This project will use CT scanning for stomach contents, plus use biomechanical and morphometric analyses to reconstruct tropic relationships of reef-dwelling organisms and test the resilience of the reef ecosystem. Several new species .... The Devonian Gogo Fauna: Diversity, Palaeoecology and Global Significance. The late Devonian Gogo Formation (380 million years old) is undoubtedly one of the richest and best-preserved assemblages of fossil fishes and invertebrates from this age anywhere on Earth. This project will use CT scanning for stomach contents, plus use biomechanical and morphometric analyses to reconstruct tropic relationships of reef-dwelling organisms and test the resilience of the reef ecosystem. Several new species will be published and the heritage significance of the site will be assessed. Working with local indigenous stakeholders, the scientific findings will feed into developing a long-term management plan to protect and conserve the site for future research work and to grow tourism in the region.Read moreRead less
Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the spe ....Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the speed of evolution at the time, and the environments in which the radiation took place. Studying the fossil evidence in the light of present-day ecological frameworks, and in comparison with modern behavioural and morphological analogues, as well as living relatives, can help us better assess our understanding of this first radiation of animals.Read moreRead less
The role of natural selection in macroevolution: a case study examining convergence of form and function in marine predator guilds. Darwin's theory of evolution natural selection is one of the most successful in the history of science and provides the framework for modern biology: however, areas of debate or uncertainty are often misinterpreted by non-scientists as indication of fundamental flaws in the theory. New 'hi-tech' tools provide the opportunity to re-examine these areas, and also to de ....The role of natural selection in macroevolution: a case study examining convergence of form and function in marine predator guilds. Darwin's theory of evolution natural selection is one of the most successful in the history of science and provides the framework for modern biology: however, areas of debate or uncertainty are often misinterpreted by non-scientists as indication of fundamental flaws in the theory. New 'hi-tech' tools provide the opportunity to re-examine these areas, and also to demonstrate the process of science to the public. The new tool is Computational Biomechanics, the future of studying biological form, and this project will further develop the leading role of Australian research in this technology which has applications for palaeontology, environmental management, medical science, and the next generation of engineering using 'biomaterials'.Read moreRead less
