Summary
Breathing streams: integrating aquatic emissions into carbon budgets. This project aims to determine the amount of greenhouse gases emitted by small streams across the Australian tropics, a potential hotspot for emissions of carbon dioxide and methane. The project expects to investigate the controls on gaseous emissions from stream to regional scales using a novel combination of gas tracer experiments, remote sensing techniques and machine learning algorithms. Expected outcomes include the devel ....Breathing streams: integrating aquatic emissions into carbon budgets. This project aims to determine the amount of greenhouse gases emitted by small streams across the Australian tropics, a potential hotspot for emissions of carbon dioxide and methane. The project expects to investigate the controls on gaseous emissions from stream to regional scales using a novel combination of gas tracer experiments, remote sensing techniques and machine learning algorithms. Expected outcomes include the development of a predictive model of gas exchange and the first estimate of gaseous emissions from the Australian tropics. This should provide significant benefits such as reducing uncertainties on the national carbon budget and avoiding misalignment of greenhouse gas abatement policies.Read moreRead less
Linking terrestrial–aquatic fluxes to rectify the Australian carbon balance. This project aims to rectify the Australian carbon balance by determining the amount of terrestrial carbon that is lost to streams and rivers across the country. Through a novel integration of high-resolution hydrochemical and gas measurements, remote sensing and machine learning algorithms, the project intends to generate new knowledge about the links between terrestrial carbon sequestration and aquatic carbon export. ....Linking terrestrial–aquatic fluxes to rectify the Australian carbon balance.

Through a novel integration of high-resolution hydrochemical and gas measurements, remote sensing and machine learning algorithms, the project intends to generate new knowledge about the links between terrestrial carbon sequestration and aquatic carbon export. Expected outcomes include a refined estimate of the net carbon sequestration potential across Australian biomes and seasons. This should provide significant benefits such as avoiding misalignment of greenhouse gas abatement policies and advancing carbon cycling models and predictions.Read moreRead less
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
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
Vulnerability of Australian savannas to climate change and variability. Australian savannas are productive and are culturally and biologically significant landscapes, but they are vulnerable to climate change. This project will determine savanna function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.

This proposal aims to establish an ultra-high-resolution, accurate mass spectrometry facility in Australia for comprehensive lipidomics research. The platform would consist of a Thermo Scientific Orbitrap Fusion mass spectrometer interfaced with ultra-high-pressure high-performance liquid chromatography. This proposal will address a major need for advanced mass spectrometry-based lipid analysis capabilities across mammalian, plant, parasite, and microalgae research disciplines, as well as enabling fundamental studies of lipid separation, chemistry and reactivity. The instrumentation would be applicable to a diverse range of projects including studies of the role of lipid metabolism in mammalian biochemistry and cell biology, plant biology and parasitology, and micro algae biofuel production.Read moreRead less
Incentivising On Country Aboriginal Employment: Anangu Futures. . This project aims to investigate the changing face of cultural tourism in central Australia and examine pathways towards sustainable aboriginal employment in and around Uluru-Kata Tjuta National Park.

This project aims to investigate the changing face of cultural tourism in central Australia and examine pathways towards sustainable aboriginal employment in and around Uluru-Kata Tjuta National Park. The project is significant because it brings together Aboriginal community members, industry and government stakeholders to identify micro-business opportunities, youth training initiatives, better relations across cultural divides, and the economic value of Aboriginal knowledge. Outcomes include a model for sustainable Aboriginal employment in remote and very remote contexts, and the development of culturally relevant and sustainable governing guidelines for regional investment. Benefits include more sustainable jobs for Aboriginal people.Read moreRead less

Summary
Mobile Australian field isotope alliance. This project will enable a quantum leap in capacity to undertake, real-time, field-based studies of environmental processes using the natural isotope tracers of carbon, oxygen and hydrogen. This will enable the project to address a range of fundamental research questions in climate change, water resources, ecology and human impact in tropical Australia.
Beyond burial: redefining the blue carbon paradigm. This project aims to constrain the magnitude and drivers of alkalinity and greenhouse gas fluxes in mangroves. Mangroves cover less than 0.03 per cent of the Earth’s surface yet account for approximately 14 per cent of oceanic carbon burial. Mangroves also export alkalinity to the coastal ocean, and act as sources of methane and nitrous oxide. The effect of these fluxes on climate may exceed carbon burial by several-fold, but are unaccounted fo ....Beyond burial: redefining the blue carbon paradigm. This project aims to constrain the magnitude and drivers of alkalinity and greenhouse gas fluxes in mangroves. Mangroves cover less than 0.03 per cent of the Earth’s surface yet account for approximately 14 per cent of oceanic carbon burial. Mangroves also export alkalinity to the coastal ocean, and act as sources of methane and nitrous oxide. The effect of these fluxes on climate may exceed carbon burial by several-fold, but are unaccounted for in blue carbon budgets. This project will couple high-resolution radionuclide geochronology of soil carbon cycling with autonomous measurements of aquatic exports and greenhouse gas fluxes. This study will provide the detailed data required to refine the blue carbon paradigm.Read moreRead less
