Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling ....Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling across a range of undisturbed to disturbed systems. It is intended that this project will provide information for conceptualising, calibrating and verifying models, including green-house gas production. Good models, and the data that support them, such as that provided by this study, are critical for the efficient allocation of management resources in Australian coastal systems, including by our partners. The findings from this project will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.Read moreRead less
Stabilisation of algal biomass harvested from coal seam gas associated water to generate a renewable, high nutrient resource. This project will develop composting technology to stabilise the biomass harvested from coal seam gas ponds. A feature of the project is consideration of toxic algal metabolites, and the potential for the release and degradation of these compounds during stabilisation.
The ecology of trace metal contamination in native Australian mammals. The ecology of trace metal contamination in native Australian mammals . This project aims to evaluate the impacts of mined trace metals on the health and performance of native Australian mammals in a northern tropical ecosystem and to determine how each species’ ecology contributes to their risk of contamination.

The ecology of trace metal contamination in native Australian mammals . This project aims to evaluate the impacts of mined trace metals on the health and performance of native Australian mammals in a northern tropical ecosystem and to determine how each species’ ecology contributes to their risk of contamination. The research also aims to give local Indigenous Rangers scientifically based strategies to improve wildlife conservation on their island. Australia’s long-term health relies on its ability to minimise the environmental costs of mining, particularly in areas characterised by high biodiversity, unique native species, or species of cultural or touristic value. Anticipated outcomes are better, more targeted strategies for conservation in mining areas.Read moreRead less
Assessing the ecosystem-wide risks of threatened species translocation. Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places. Moving threatened plants and animals to new environments, or reintroducing them where they previously persisted, is a growing focus of conservation. Moving species can have unanticipated effects on other specie ....Assessing the ecosystem-wide risks of threatened species translocation. Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places. Moving threatened plants and animals to new environments, or reintroducing them where they previously persisted, is a growing focus of conservation. Moving species can have unanticipated effects on other species in the ecosystem. Although the International Union for Conservation of Nature deems ecosystem-wide risk assessments essential for conservation translocations, no framework exists to assess these risks and inform these decisions. New tools for assessing the risks of conservation translocations are expected to improve global and local conservation outcomes.Read moreRead less
Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will b ....Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less

Ecological valuation tools to protect seagrass during coastal development. Focussing on differences between shallow and deep seagrasses in the Great Barrier Reef, this project aims to develop a spatial valuation tool so resource managers and policy makers can minimise the effect of port development on seagrass ecosystems. Seagrasses provide ecosystem services (fisheries, nutrient cycling, primary productivity) worth trillions of dollars, but coastal development threatens this capacity. Resource managers lack accurate information about their potential effect and mitigation measures. Anticipated outcomes are protection of key marine environment and World Heritage Assets, and benefits to Australia’s economy through maintenance of ecosystem services and reduced risk associated with development.Read moreRead less
Restoring ecosystem function in altered landscapes to achieve ecologicallly sustainable development goals. Mining and agriculture contribute approximately 10 per cent of Australia's gross domestic product. Hence the sustainable development of these sectors is critical to our long term economic growth and well being. However, this growth is leading to degradation of landscape ecosystem function and loss of ecosystem services. Community reaction will curtail production in these sectors where funct ....Restoring ecosystem function in altered landscapes to achieve ecologicallly sustainable development goals. Mining and agriculture contribute approximately 10 per cent of Australia's gross domestic product. Hence the sustainable development of these sectors is critical to our long term economic growth and well being. However, this growth is leading to degradation of landscape ecosystem function and loss of ecosystem services. Community reaction will curtail production in these sectors where function and services continue to be lost. This project addresses the demand for accurate scientific information, needed by industry and government, to understand ecosystem responses to change, and to develop optimal conservation interventions that take account of the costs and benefits in landscapes where the intensive mining industry intersects with extensive land uses for food and fibre production.Read moreRead less
Unravelling the cycling of nitrogen along a subtropical freshwater-marine continuum using a multi-isotope, multi-tracer and modelling approach. This project will significantly advance our understanding of the sources, cycling and pathways of nitrogen along a sub-tropical catchment-river-estuary. As such, the findings from this research will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.
