Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed ....Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed knowledge of how changes in fire and rain shaped the ecology and evolution of plants and animals. This knowledge is key to understanding how Australian ecosystems function and to protecting their cultural, economic and environmental values, especially as climate and fire regimes continue to change into the future.Read moreRead less
Generalised methods for testing extinction dynamics across geological, near and modern time scales. The record of extinctions over deep time is patchy and incomplete, yet we must use it to determine how major changes in past environments have shaped life on Earth today. The project will develop cutting-edge mathematical tools to determine the patterns of extinctions and speciation over geological time to help predict our uncertain environmental future.
Resolving how five million years of dramatic climatic changes shaped Australia's unique fauna. Australia’s biota is a product of its unique heritage, tectonic history and most especially its climate. Over the past five million years it has been beset by a series of intense climatic shifts driven by a combination of global and regional factors. This project will be the first to track faunal responses to environmental changes across this critical interval. It will establish the dynamics of the ori ....Resolving how five million years of dramatic climatic changes shaped Australia's unique fauna. Australia’s biota is a product of its unique heritage, tectonic history and most especially its climate. Over the past five million years it has been beset by a series of intense climatic shifts driven by a combination of global and regional factors. This project will be the first to track faunal responses to environmental changes across this critical interval. It will establish the dynamics of the origin of the modern southern vertebrate fauna, analysing changes in diversity, diet and community structure. By exploring associations between phases of faunal turnover and key climatic transitions, it will bring a Southern Hemisphere perspective to evolutionary models of Cenozoic faunal change largely generated to date from Northern Hemisphere data.Read moreRead less
Faunal responses to past climatic and human impacts in eastern Australia. The Wellington Caves in central eastern New South Wales are Australia's most historically significant fossil locality and preserve one of the world's most complete records of vertebrate life spanning the past 4 million years. To date this unique archive has been vastly under-exploited as a source of information on how faunas respond to increased aridity and climatic variability, as well as human activities over the past 50 ....Faunal responses to past climatic and human impacts in eastern Australia. The Wellington Caves in central eastern New South Wales are Australia's most historically significant fossil locality and preserve one of the world's most complete records of vertebrate life spanning the past 4 million years. To date this unique archive has been vastly under-exploited as a source of information on how faunas respond to increased aridity and climatic variability, as well as human activities over the past 50 000 years. This project aims to elucidate how climate change drove the evolution of the modern fauna of eastern Australia by analysing changes in diversity, diet and community structure over time. It may also help break the 130-year climate-versus-humans deadlock over what drove the Pleistocene megafaunal extinctions.Read moreRead less
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.
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.
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
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. By examining biological processes before, during, and after major changes (eg coral bleaching, salination) the evolution and selective pressures at important genetic loci will be identified, and related to ....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. By examining biological processes before, during, and after major changes (eg coral bleaching, salination) the evolution and selective pressures at important genetic loci will be identified, and related to environmental change to enhance effected planning and future management of Australia's ecosystems, biodiversity and tourism. Key records will come from lake-beds, billabongs, coral reefs, rodent nests, megafaunal bones, and ancient human material.Read moreRead less

Using ancient microbiomes and genomes to reconstruct human history. This project aims to generate unique insights into the processes and history that produced the current distribution of modern humans and the bacteria we carry with us (our microbiome). The project will use combined signals of bacterial, genomic and climate data to reconstruct the impacts of migrations, changes in diet, environment, and health in different parts of the world. A key aspect will be the creation of a program to map the genetic history of indigenous Australia, and the impacts of colonisation on indigenous people around the world. Research advances will be transferred to Early Career Researchers through an innovative program of workshops, and the resulting data will be used to create a new format for Australian genetic databases.Read moreRead less
