This project aims to develop innovative laser cleaning processes to conserve the structural integrity and iconic status of the Sydney Harbour Bridge. New laser technologies offer the opportunity to remove lead-based paint and clean the bridge’s metal structures and granite pylons offering advantages unavailable with current techniques. The expected outcomes will be new best-practice laser conservation techniques usable for both hand-held and automated systems to preserve one of the most iconic bridges in the world. This will reduce maintenance frequency and cost, restore the beauty of the bridge, retain its engineering significance and provide a baseline process for cleaning of other historical large scale metal and stone heritage objects.Read moreRead less

Innovative enhancement and management of threatened temperate woodlands for improved biodiversity conservation. We will test the broad question: Does woodland management affect woodland biota, and if so, which groups and in what ways? To answer this, we will quantify the effects of major woodland treatments (prescribed fire, timber addition, grazing control) on animals. We will implement a long-term, large-scale 'natural experiment' to provide critical data & analyses on the simultaneous effects ....Innovative enhancement and management of threatened temperate woodlands for improved biodiversity conservation. We will test the broad question: Does woodland management affect woodland biota, and if so, which groups and in what ways? To answer this, we will quantify the effects of major woodland treatments (prescribed fire, timber addition, grazing control) on animals. We will implement a long-term, large-scale 'natural experiment' to provide critical data & analyses on the simultaneous effects of management regimes on woodland biota. A key outcome will be an improved understanding of woodland biota response to management critical for use on grazing properties, reserves, travelling stock routes in rural south-eastern Australia. This will be a major step forward given that temperate woodlands are among Australia's most threatened vegetation types.Read moreRead less
Marine conservation planning for persistent coral reef communities: Incorporating connectivity and resilience. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. However, despite substantial efforts to conserve marine ecosystems, Australian coral reefs are at increasing risk from climate change related catastrophes. To counteract this trend, we must choose marine reserve networ ....Marine conservation planning for persistent coral reef communities: Incorporating connectivity and resilience. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. However, despite substantial efforts to conserve marine ecosystems, Australian coral reefs are at increasing risk from climate change related catastrophes. To counteract this trend, we must choose marine reserve networks using methods that account for the dynamic nature of climate change and reef community responses to maximise the persistence of reef biodiversity. The new theory and methods will enable us to create more effective and economically efficient marine reserve systems.Read moreRead less
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
Creating conservation landscapes that effectively safeguard biodiversity. The current extinction crisis creates an imperative to protect remaining habitat wherever it occurs. This project aims to reveal how to improve protection for biodiversity outside of designated Protected Areas by advancing the concept of Conserved Areas, where conservation can be a product of other goals.

The current extinction crisis creates an imperative to protect remaining habitat wherever it occurs. This project aims to reveal how to improve protection for biodiversity outside of designated Protected Areas by advancing the concept of Conserved Areas, where conservation can be a product of other goals. This project is expected to generate novel insights into how to recognise Conserved Areas, reveal the risks and benefits associated with different type of protection and develop vital tools to ensure these areas effectively conserve biodiversity. Benefits will include a blueprint to meet global environmental commitments using well-designed systems of Protected and Conserved Areas as part of integrated conservation landscapes.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.
