Conjugate natural convection boundary layers. Conjugate natural convection systems occur when a conducting vertical wall separates fluids at different temperatures (that is at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator). This project will provide accurate predictions of such flows together with scaling relations.
Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy ....Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.Read moreRead less
Orientation in the pelagic environment: how do larval marine fish find their way home? This study will determine what senses tiny fish larvae use to orientate in the ocean and to influence where currents disperse them. Because larval dispersal determines the spatial extent of fish populations, this knowledge is important for management of marine fisheries and the design and operation of marine parks.
Ecologically responsible mining to fuel a green energy transition. An energy transition is key to tackling climate change. However, renewable energy is mineral intensive and boosting its supply may create new mining threats to biodiversity. This project aims to facilitate strategic development of ecologically responsible mining. It expects to reveal where new mines will be needed to meet future energy demand, and create innovative tools to predict and mitigate threats to plants and animals. Expe ....Ecologically responsible mining to fuel a green energy transition. An energy transition is key to tackling climate change. However, renewable energy is mineral intensive and boosting its supply may create new mining threats to biodiversity. This project aims to facilitate strategic development of ecologically responsible mining. It expects to reveal where new mines will be needed to meet future energy demand, and create innovative tools to predict and mitigate threats to plants and animals. Expected outcomes include an improved ability to inform sustainable climate and energy policies, leading to strategic investment decisions, cleaner mineral supply chains and conservation outcomes that capture valuable environmental and social benefits and create a competitive advantage for Australia’s mining sector.Read moreRead less
The roles of stress and immunocompetence in biological invasions. Invasive species pose a major threat to biodiversity worldwide; and within Australia, cane toads are widely viewed as one of the biggest such problems. Building on recent studies that reveal weakened immune systems in invasion-front toads, this project will provide a comprehensive understanding of immune responses in cane toads and native frogs, with the aim of exploiting the toads' immunocompromised state to develop new and more ....The roles of stress and immunocompetence in biological invasions. Invasive species pose a major threat to biodiversity worldwide; and within Australia, cane toads are widely viewed as one of the biggest such problems. Building on recent studies that reveal weakened immune systems in invasion-front toads, this project will provide a comprehensive understanding of immune responses in cane toads and native frogs, with the aim of exploiting the toads' immunocompromised state to develop new and more effective control measures. The project will develop a new paradigm about the roles of stress and immunity in biological invasion, applicable to the control of other invasive species and to understanding processes at work when environmental changes force species to shift their ranges.Read moreRead less
An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Keystone effects of Australia's top predators: dingoes, devils and biodiversity. This project will study the interactions of Australia's two largest predators, the dingo and Tasmanian devil, with other species. The project will help develop an understanding of the value of these predators in maintaining ecosystem processes and diversity, and guide their management in the future.
New generation nanostructured coatings with combined control of spectral and angular emissivity. The aim of this project is to generate a complete scientific understanding of a new generation of hybrid, tri-layered, optically-selective coatings. The new design paradigm combines the very different attributes of smooth and nanostructured layers so that superior and simultaneous control of both spectral and angular properties of light can be achieved. Existing theory will be extended so that quanti ....New generation nanostructured coatings with combined control of spectral and angular emissivity. The aim of this project is to generate a complete scientific understanding of a new generation of hybrid, tri-layered, optically-selective coatings. The new design paradigm combines the very different attributes of smooth and nanostructured layers so that superior and simultaneous control of both spectral and angular properties of light can be achieved. Existing theory will be extended so that quantitative analyses of these new systems and other hybrids become possible and new and improved fabrication techniques will be developed. The work will unlock new technological possibilities for coating performance and application and is likely to be associated with significant improvements in energy conservation and generation.

Unraveling the mystery of the Plain of Jars, Laos. Since their discovery in the 1930s, the mysterious collections of giant stone jars scattered throughout central Laos have remained one of the great prehistoric puzzles of south-east (SE) Asia. It is thought that the jars represent the mortuary remains of an extensive and powerful Iron Age culture. This project seeks to determine the true nature of these sites, which date to a dynamic period of increasing complexity in SE Asia (c.500BCE-500CE). T ....Unraveling the mystery of the Plain of Jars, Laos.

Using a suite of cutting-edge archaeological technologies, it is expected to have far-reaching benefits for archaeology, science, Laos and World Heritage.Read moreRead less
Disperse or die: the evolution of dispersal ability in a changing climate. Whether or not climate change will affect a species depends upon the ability of ecological communities to track climate change. Species that rapidly shift their range in response to climate change will not be unduly affected, whereas species that are stuck in one place are at extreme risk from a changing climate (they must either adapt, or perish). We need, therefore, a firm understanding of how, and how rapidly, specie ....Disperse or die: the evolution of dispersal ability in a changing climate. Whether or not climate change will affect a species depends upon the ability of ecological communities to track climate change. Species that rapidly shift their range in response to climate change will not be unduly affected, whereas species that are stuck in one place are at extreme risk from a changing climate (they must either adapt, or perish). We need, therefore, a firm understanding of how, and how rapidly, species shift their range. This project will develop a universal framework within which to model species' responses to climate change. As such, the project will contribute greatly to how we plan for, and manage, the effects of climate change.Read moreRead less
