The Impact of Water Stress on Early Humans in the Kalahari Desert. This project aims to understand the impacts of water stressed environments for early modern human behaviour through state-of-the-art excavation techniques and palaeoenvironmental reconstruction at two new archaeological sites in the Kalahari. How humans mitigated water stress during a major technological transition is significant because adaptability to arid environments was crucial for humans expanding beyond Africa and into Aus ....The Impact of Water Stress on Early Humans in the Kalahari Desert. This project aims to understand the impacts of water stressed environments for early modern human behaviour through state-of-the-art excavation techniques and palaeoenvironmental reconstruction at two new archaeological sites in the Kalahari. How humans mitigated water stress during a major technological transition is significant because adaptability to arid environments was crucial for humans expanding beyond Africa and into Australia. The expected outcome of this project is creation of new knowledge on the origins of human resilience to water stress. The benefit lies in the potential to gain insights into meeting future climate challenges by exploring the adaptive strategies developed by early modern humans in the southern Kalahari.Read moreRead less

A high throughput phenomics facility for pace of life traits in animals. A high throughput phenomics facility for pace of life traits in animals: This project seeks to create the first high-throughput phenomic facility for animals in Australia. The molecular revolution has brought unprecedented capacity to understand genetic variation. Genetic variation is now better understood and more easily and cheaply characterised than the physical traits that organisms exhibit. Linking phenotypic variation ....A high throughput phenomics facility for pace of life traits in animals. A high throughput phenomics facility for pace of life traits in animals: This project seeks to create the first high-throughput phenomic facility for animals in Australia. The molecular revolution has brought unprecedented capacity to understand genetic variation. Genetic variation is now better understood and more easily and cheaply characterised than the physical traits that organisms exhibit. Linking phenotypic variation to genetic variation represents the major challenge in harnessing the power of the biomolecular age. This facility will accommodate animals from marine, freshwater and terrestrial systems across a diverse array of phyla. It will allow Australian researchers to leverage advances in high throughput genomic technologies to address a major bottleneck in biology.Read moreRead less
The ecology of parasite transmission in fauna translocations. Parasitic diseases pose a threat to the conservation management of Australia's biodiversity. This project will improve our understanding of the impact and transmission of parasites in fauna translocations, contributing to the conservation management of Australian ecosystems by government and private agencies.
How a ubiquitous endosymbiont of insects protects against pathogens. The project intends to determine the mechanism that underpins pathogen protection in insects. Insects harbour microbial communities in their cells and guts and confer a range of benefits on their hosts. One bacterium, Wolbachia, protects insects against co-infecting pathogens. The release of Wolbachia into mosquito populations is currently being tested as a means to reduce dengue virus transmission to humans. Using innovative e ....How a ubiquitous endosymbiont of insects protects against pathogens. The project intends to determine the mechanism that underpins pathogen protection in insects. Insects harbour microbial communities in their cells and guts and confer a range of benefits on their hosts. One bacterium, Wolbachia, protects insects against co-infecting pathogens. The release of Wolbachia into mosquito populations is currently being tested as a means to reduce dengue virus transmission to humans. Using innovative evolutionary and genetic approaches, the project proposes to elucidate the mechanism of pathogen blocking and ascertain its broader consequences for the host. This knowledge may be critical for maintaining the effectiveness of the biocontrol approach in the field by informing the development of resistance management strategies.Read moreRead less

Summary
Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic pe ....Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic performance under elevated CO2, and the importance of habitat in how fish respond to elevated CO2. As fish play critical roles in marine ecosystems by structuring food webs and driving ecological processes, this information will be critical for predicting the effects of ocean acidification on marine ecosystems and biodiversity.Read moreRead less
Are good males bad females? Sexual conflict in hermaphrodites. Animal hermaphrodites (organisms that are both males and females) are extremely common and important from both an economic and ecological perspective but we know little about the evolution of this group. This project will examine how sexual conflict, so pervasive in organisms with separate sexes, affects the evolution of hermaphrodites.
Geomolecular dating with biologically relaxed clocks, and mammal evolution. This project aims to use DNA, fossils and biological cues to synergistically model evolutionary rate changes. Molecular dates allow direct comparison of evolutionary and ecological patterns and processes across the tree of life. However, current models struggle to identify the location and magnitude of molecular clock rate changes on phylogenies, often resulting in wildly inaccurate dates. Expected outcomes include impro ....Geomolecular dating with biologically relaxed clocks, and mammal evolution. This project aims to use DNA, fossils and biological cues to synergistically model evolutionary rate changes. Molecular dates allow direct comparison of evolutionary and ecological patterns and processes across the tree of life. However, current models struggle to identify the location and magnitude of molecular clock rate changes on phylogenies, often resulting in wildly inaccurate dates. Expected outcomes include improved dating accuracy, and a novel statistical framework for morphological data, which allows fossils to be more accurately merged into the tree of life. In turn, the project aims to resolve intense debate on the origins of marsupial and placental mammals, and to trace the responses of these two groups to past environmental changes.Read moreRead less
