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. 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 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
Does physiological plasticity of individuals render populations resilient to climate change? Abrupt environmental changes can put natural populations at risk of extinction. The project will show to what extent individuals can compensate for temperature changes and thereby render populations resilient to climate change. This research will make theoretical advances and improve the power to predict impacts of future climate change.

I will establish a network of international and national collaborators and improve knowledge on how animals responded to past environmental change. The anticipated outcome of this project is to improve our ability to understand, measure and preserve our ....Comparative genomics to improve conservation planning in Australian deserts. This project aims to locate hotspots of diversity in Australia’s vast, flat deserts and to quantify how well these areas are captured under the National Reserve System. I will establish a network of international and national collaborators and improve knowledge on how animals responded to past environmental change. The anticipated outcome of this project is to improve our ability to understand, measure and preserve our unique desert biodiversity and the evolutionary processes that sustain it, using our remarkably diverse reptile fauna as a model system. In the face of current, rapid environmental change, this has never been more important, and will provide a tool for biodiversity survival.Read moreRead less

Summary
Adaptive evolution and its demographic consequences today. This project aims to provide the first test of whether the rate of adaptative genetic evolution has changed in the recent decades, to quantify how much recent genetic evolution helps animal populations survive, and to increase the ability to study on-going genetic evolution in Australian wildlife. The project is of major significance as many species are currently threatened, or invading, due to rapid environmental changes, in particular ....Adaptive evolution and its demographic consequences today. This project aims to provide the first test of whether the rate of adaptative genetic evolution has changed in the recent decades, to quantify how much recent genetic evolution helps animal populations survive, and to increase the ability to study on-going genetic evolution in Australian wildlife. The project is of major significance as many species are currently threatened, or invading, due to rapid environmental changes, in particular climate change. The anticipated outcome of the project is to deliver new methods, establish a network of international and national collaborators and improve the ability to measure and to forecast how Australian animals adapt to rapidly changing environments.Read moreRead less
How does the interaction between environmental drivers determine the impact of global change on animals? There is an urgent need to determine how vulnerable natural populations are to simultaneous changes in more than one environmental driver. This project will take an integrative approach, using molecular, physiological and ecological tools, to determine whether cellular responses to the interaction between UV-B radiation and temperature vary between populations, and within individuals over tim ....How does the interaction between environmental drivers determine the impact of global change on animals? There is an urgent need to determine how vulnerable natural populations are to simultaneous changes in more than one environmental driver. This project will take an integrative approach, using molecular, physiological and ecological tools, to determine whether cellular responses to the interaction between UV-B radiation and temperature vary between populations, and within individuals over time. This project will bridge the gap between physiology and ecology by testing whether molecular responses translate into fitness benefits for the organism to gain an understanding at a level that is relevant for conservation.

Transitions between modes of sex-determination in a changing world. Sex-determination controls the largest variation within animals—the division into males and females. While the different systems of sex-determination—involving genetic or environmental control—are fairly well understood, transitions between these systems remain enigmatic in evolutionary biology. This project aims to address this gap by revealing the molecular change required to transition between systems, using one of only two k ....Transitions between modes of sex-determination in a changing world. Sex-determination controls the largest variation within animals—the division into males and females. While the different systems of sex-determination—involving genetic or environmental control—are fairly well understood, transitions between these systems remain enigmatic in evolutionary biology. This project aims to address this gap by revealing the molecular change required to transition between systems, using one of only two known lizard species exhibiting both genetic and temperature control of sex. This knowledge will have important implications for species conservation, facilitating predictions of highly biased sex ratios under climate change, plus potential commercial applications for species where production of one sex is favoured.Read moreRead less
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
Genomics for persistence of Australian freshwater fish. Biodiversity faces an unpredictable cocktail of impacts and global environmental change, against which the best insurance is genetic diversity. We will develop genomic measures of ecological-genetic functions and evolutionary potential for managing Australian freshwater fish.
Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral ....Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral-algal symbioses. It will provide much-needed knowledge required to identify associations most appropriate for specific conditions, prioritise populations for conservation, and assess the feasibility of new approaches to managing and restoring coral reefs.
