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.

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

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. 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. 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
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.
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interacti ....The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less

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

Summary
The Darwin Prospective Melioidosis Study has documented 761 cases since 1989, with 102 fatalities. This study has led to improved therapy and public health initiatives. New technology to sequence whole bacterial genomes provides an opportunity to determine why urban melioidosis is increasing and to analyse this unique 22+ year set of bacteria and their linked patient data to find the important bacterial virulence factors, forming a foundation for future diagnostics, therapeutics, and vaccines.
Threats to the water quality and ecosystem of Coffin Bay, South Australia. Coffin Bay (South Australia) is experiencing worsening environmental conditions despite its major economic and ecological importance.

Coffin Bay (South Australia) is experiencing worsening environmental conditions despite its major economic and ecological importance. Research is needed to understand the cause of this decline, particularly in light of a recent bacterial outbreak that impacted the aquaculture industry. This multidisciplinary project aims to deliver world-leading scientific advice based on novel field techniques and innovative models of this complex inverse estuary system and its surrounding catchment. The new understanding of the sources, fluxes and fate of nutrients within the bay and the surrounding catchment, arising from this project, is expected to benefit management decision-making and establish a new standard in estuarine water quality investigation.Read moreRead less

Temporal control of cell function aligns biological pathways with environmental cues and is critical for optimal heath in mammals. This project will shed light on how a hormone receptor, the MR, modulates time keeping of biological clock time in cells. We will bring together cutting edge genetic modals and bioinformatic approaches with a unique set of research models to define the interaction between the MR and the circadian clock and its role in the normal biology of the heart. New data will significantly enhance our understanding of the biology of MR and cortisol for the circadian time keeping function in peripheral tissues, and gain a clearer understand how our heart cells adapt to environmental circadian disruptors such as shift work.

Improved Indigenous population projections for policy and planning. This project will use a range of methods to understand the population dynamics of the Australian Aboriginal and Torres Strait Islander (Indigenous) population. This information will allow policy makers to plan and target resources and help Indigenous organisations understand what is happening to the population in their communities.
