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

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

Summary
The neurological correlates of periodic breathing in insects. While at rest many animals switch from breathing continuously to displaying long breath-hold periods between periods of ventilation. The neurological mechanisms responsible for generating this respiratory pattern will be investigated using insects that display a discontinuous pattern of breathing.

Summary
Building community resilience to coastal climate hazards in Australia. More frequent and intense climate hazards are devastating Australian communities and are projected to worsen as climate changes. This project aims to develop and communicate urgently needed strategies to assist coastal communities to prepare for and respond to climate hazards. The relationship between local-scale connection and capacity to prepare and respond will be investigated using mixed methods research in at-risk commun ....Building community resilience to coastal climate hazards in Australia. More frequent and intense climate hazards are devastating Australian communities and are projected to worsen as climate changes. This project aims to develop and communicate urgently needed strategies to assist coastal communities to prepare for and respond to climate hazards. The relationship between local-scale connection and capacity to prepare and respond will be investigated using mixed methods research in at-risk communities. The research will deliver practical guidance to policy makers and managers that will optimise investments in building community resilience, advance the discipline of human geography, and benefit over 20 million Australians living in coastal areas by creating new knowledge on neighbourhood adaptive capacity.Read moreRead less

Summary
Can species interactions drive diversification? Species interactions may drive the evolution of species diversity but we currently lack the empirical evidence to demonstrate conclusively how this occurs. Using a group of closely-related species native to Australia's rainforest, this study will test how species interactions drive the evolution of mating traits and the formation of new species.

Summary
How adaptation increases the intensity of sexual conflict. This project aims to test a theory that a species’ adaptation to its environment may cause sexual conflicts where gene variants increase the fitness of one sex but decrease it in the other. When populations harbour large numbers of these sexually antagonistic genes, adaptation is hampered and extinction becomes more likely. This project will fuse experimental evolution with quantitative genetic approaches to test this theory. Understandi ....How adaptation increases the intensity of sexual conflict. This project aims to test a theory that a species’ adaptation to its environment may cause sexual conflicts where gene variants increase the fitness of one sex but decrease it in the other. When populations harbour large numbers of these sexually antagonistic genes, adaptation is hampered and extinction becomes more likely. This project will fuse experimental evolution with quantitative genetic approaches to test this theory. Understanding sex differences in adaptation and the evolution of sexual dimorphism could enable scientists to predict levels of sexually deleterious variation under changing environmental conditions. Its findings are expected to provide new insights into sex differences in adaptation.Read moreRead less

This project aims to understand how morality influences adaptation to climate change in the Great Barrier Reef region. This project expects to generate new knowledge in the critical area of climate change adaptation, using an interdisciplinary approach. Expected outcomes include empirical insights into the connection between morality and adaptation, international collaborations, theory development, and refined methods to help identify leverage points for incorporating morality into climate change decision-making. This should provide significant benefits, including a basis for policy-making in Australia and globally, that supports effective and just adaptation to climate change in ways that sustain livelihoods and respect local values.Read moreRead less

This project aims to develop novel catalysts for high-efficient nitrogen fixation by learning from the natural enzymes, which can convert nitrogen or nitrate into reactive ammonia at very mild conditions. It is expected that the enzyme-mimicking catalysts possessing the nitrogen active sites similar with the natural enzymes will allow the effective fixation of nitrogen from both the atmosphere and the nitrogen excessively fertilized environment into reusable ammonia. The outcomes of this project will provide a sustainable approach to solve the issues in current unbalanced inorganic nitrogen cycle in the world and contribute to a green artificial nitrogen cycle while with minimized environmental impact.Read moreRead less

Summary
Understanding how shared between-sex genetic variance constrains the evolution of sexual dimorphism. Differences between males and females in the expression of shared traits have been of lasting interest to biologists. One fundamental question, which is as yet poorly understood, regards the extent to which a common genome restricts the independent evolution of the sexes. This project proposes a novel way of examining the degree to which the shared genetic architecture restricts the evolution of ....Understanding how shared between-sex genetic variance constrains the evolution of sexual dimorphism. Differences between males and females in the expression of shared traits have been of lasting interest to biologists. One fundamental question, which is as yet poorly understood, regards the extent to which a common genome restricts the independent evolution of the sexes. This project proposes a novel way of examining the degree to which the shared genetic architecture restricts the evolution of the sexes and the costs this imposes on population fitness. The results from the proposed experiments will give a clearer picture of how current measures reflect the true genetic constraint imposed on the sexes from a shared genetic architecture.Read moreRead less
