Coral-associated viruses: pathogens, mutualists and agents of evolution? Corals host numerous organisms, of which viruses are the least studied. The aim of this project is to characterise the viruses associated with corals and to obtain a detailed understanding of the critical roles that viruses play in coral health, coral bleaching and adaptation of corals to climate change.
Revealing the structure, evolution and sensitivity of symbioses in basal metazoa. This project will explore the complex interactions between each component of the sponge holobiont (virus, bacteria, sponge) during thermal stress. This will also provide the first molecular assessment of sponge viruses and provide insights into how sponges may adapt to a changing climate.

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
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less
The basis of oyster resilience to global environmental change. This project aims to investigate the impact of global environmental change on the survival of Australia’s oyster industry, by combining the science of genetics, physiology and ecology to identify already resilient oysters. Through the first complete understanding of resilience in oysters, including the trade-offs they have made in other fitness traits, the project develops new capacities to 'climate and future-proof' our natural oyst ....The basis of oyster resilience to global environmental change. This project aims to investigate the impact of global environmental change on the survival of Australia’s oyster industry, by combining the science of genetics, physiology and ecology to identify already resilient oysters. Through the first complete understanding of resilience in oysters, including the trade-offs they have made in other fitness traits, the project develops new capacities to 'climate and future-proof' our natural oyster populations and the Australian oyster industry, to enable the restoration of degraded oyster habitats. This project will ensure the future of an iconic and economically important national industry and food source and contribute to preserving the critical cultural links of Indigenous Australians with their lands.Read moreRead less
Peripheral isolates as hotbeds of adaptive diversity. This project uses cutting edge molecular technology and spatial analyses to predict the location of diversity relevant to managing the impact of climate change. Knowledge generated in this project will open the door to the informed use of genetic translocation in efforts to kerb expected biodiversity losses.
Why does the genetic nearly-null subspace exist? This project aims to determine why nearly-null genetic subspaces exist by simultaneously measuring the input of new mutational variance in these nearly-null subspaces and the selection that acts on these new mutations to result in the observed low levels of standing genetic variance. The ability of organisms to evolve in response to human disturbance, translocation to new environments, or climate variation is governed by the availability of geneti ....Why does the genetic nearly-null subspace exist? This project aims to determine why nearly-null genetic subspaces exist by simultaneously measuring the input of new mutational variance in these nearly-null subspaces and the selection that acts on these new mutations to result in the observed low levels of standing genetic variance. The ability of organisms to evolve in response to human disturbance, translocation to new environments, or climate variation is governed by the availability of genetic variation. Recent advances in multivariate genetic analysis have demonstrated that a substantial proportion of a phenotype described by quantitative traits has very little genetic variance associated with it, and will therefore tend to be subjected to evolutionary limitsRead moreRead less

Summary
The effect of apparent stabilising selection on genetic architecture. This project aims to improve our understanding of the cause of evolutionary limits. It will test the prediction that trait combinations with high genetic variation are highly correlated with other traits, and therefore are more evolutionary limited than they appear. This project will develop and implement novel evolutionary and statistical manipulations and methods to test this prediction, and is expected to provide new method ....The effect of apparent stabilising selection on genetic architecture.

It will test the prediction that trait combinations with high genetic variation are highly correlated with other traits, and therefore are more evolutionary limited than they appear. This project will develop and implement novel evolutionary and statistical manipulations and methods to test this prediction, and is expected to provide new methods for the study of selection. A better understanding of evolutionary limits will provide a significant benefit, enabling better predictions of how natural populations will evolve over short and long time-scales, and their risks of extinction.Read moreRead less

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
