Coral reef connectivity: an empirical and theoretical synthesis. Australia possesses the greatest marine biodiversity of any first world country and this biodiversity is a major contributor to our economic wealth. Nonetheless, Australia's coral reef communities are threatened by various human activities and climate change. Wisely designed systems of marine reserves are critical to mitigating threats to coral reefs, but existing approaches do not incorporate crucial information about ecological c ....Coral reef connectivity: an empirical and theoretical synthesis. Australia possesses the greatest marine biodiversity of any first world country and this biodiversity is a major contributor to our economic wealth. Nonetheless, Australia's coral reef communities are threatened by various human activities and climate change. Wisely designed systems of marine reserves are critical to mitigating threats to coral reefs, but existing approaches do not incorporate crucial information about ecological connections between reefs. We will use graph theory metrics to identify priority reefs for protection based on empirical genetic and hydrological connectivity information. In addition, we will determine the sensitivity of these priorities to climate change scenarios.Read moreRead less
Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a pr ....Geometry of wall-turbulence and its potential to advance scalable models. This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a predictable geometric structure, and the notorious complexity of turbulent wall-flow dynamics could be clarified through its inherent geometry. This project expects to construct a basis for predicting engineering and atmospheric wall-flows, which would enhance atmospheric flow prediction, reduce energy consumption and further environmental sustainability.Read moreRead less
Self-similar scale interactions in turbulent boundary layers. Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future. While recent research has yielded a clearer physical understanding of these flows, converting this understanding into tools useful to engineering practice remains a central obstacle. The proposed research directly addresses this fundamental challenge ....Self-similar scale interactions in turbulent boundary layers. Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future. While recent research has yielded a clearer physical understanding of these flows, converting this understanding into tools useful to engineering practice remains a central obstacle. The proposed research directly addresses this fundamental challenge by precisely connecting the eddy interactions of the turbulence to the mathematical equations that rigorously describe these flows. As such it holds breakthrough potential toward the development of turbulent boundary layer prediction and control schemes that do not rely on ad hoc models or assumptions.Read moreRead less
Novel species interactions arising from synergistic environmental changes. Synergistic environmental changes, including climate and land use change, are altering Australia's ecosystems and creating novel species assemblages. We know little about how these assemblages develop and function, and yet they are likely to become more pervasive and provide a significant conservation and restoration challenge. We aim to improve our understanding of the factors affecting the creation of novel plant assemb ....Novel species interactions arising from synergistic environmental changes. Synergistic environmental changes, including climate and land use change, are altering Australia's ecosystems and creating novel species assemblages. We know little about how these assemblages develop and function, and yet they are likely to become more pervasive and provide a significant conservation and restoration challenge. We aim to improve our understanding of the factors affecting the creation of novel plant assemblages (through invasions and changes in species' ranges) in the York Gum woodlands of Western Australia. We will examine how novel assemblages function, improve the ability to predict potential ongoing changes in assemblages and provide guidance for the management of these and other internationally important plant communities.Read moreRead less
Why conserve genetic variation? Is this misdirected effort or a crucial concern? In attempting to conserve populations of threatened plants, ecosystem managers must prioritise allocation of resources to both immediate and long-term threats, including loss of genetic variation. This study will determine the importance of maintaining existing genetic variation within populations of several species in a major Australian plant group. As well as advancing theory in the area of plant ecological genet ....Why conserve genetic variation? Is this misdirected effort or a crucial concern? In attempting to conserve populations of threatened plants, ecosystem managers must prioritise allocation of resources to both immediate and long-term threats, including loss of genetic variation. This study will determine the importance of maintaining existing genetic variation within populations of several species in a major Australian plant group. As well as advancing theory in the area of plant ecological genetics and evolutionary biology, our results will provide a stronger scientific basis for the development of conservation policy and management decisions for conserving threatened plant species.

Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the deve ....Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the development of better strategies to manage their impacts. The project will also build Australia's wider capacity to manage outbreaks of infectious diseases.Read moreRead less
Sustainable Farms: Tree Regeneration and the Future of Farmland Biodiversity. While many government and community initiatives aim to enhance the sustainability of Australian farming systems, none specifically target the important regional-scale threatening process of tree recruitment failure. Unless this problem is addressed urgently, many farming landscapes may be virtually treeless in the future, with severe negative ramifications for both biodiversity and agricultural productivity. 'Sustainab ....Sustainable Farms: Tree Regeneration and the Future of Farmland Biodiversity. While many government and community initiatives aim to enhance the sustainability of Australian farming systems, none specifically target the important regional-scale threatening process of tree recruitment failure. Unless this problem is addressed urgently, many farming landscapes may be virtually treeless in the future, with severe negative ramifications for both biodiversity and agricultural productivity. 'Sustainable Farms' will have major national and community benefits because it will: (1) identify more sustainable farming practices that are conducive to successful tree recruitment in the future, and (2) raise awareness about a much neglected threat to the sustainability of Australian farming landscapes.Read moreRead less
Managing the evolutionary potential of fragmented native plant populations. Many previously widespread plant species now exist in small fragmented populations threatened with extinction due to genetic decline. We will apply a novel and powerful new genetic approach for the assessment of the evolutionary potential of these populations. Through the most detailed characterisation of realized mating yet possible, we will determine if recently fragmented populations are in genetic decline, and how ....Managing the evolutionary potential of fragmented native plant populations. Many previously widespread plant species now exist in small fragmented populations threatened with extinction due to genetic decline. We will apply a novel and powerful new genetic approach for the assessment of the evolutionary potential of these populations. Through the most detailed characterisation of realized mating yet possible, we will determine if recently fragmented populations are in genetic decline, and how anciently fragmented species avoid extinction. Our aim is to generate general principles for the early measurement and/or prediction of genetic decline in species most at risk, that will enable us to determine how and when remediation measures are required.Read moreRead less
