Reef Breath Testing (RBT): exhaled volatile-gas biomarkers of coral health. This Project aims to uncover volatile gas "fingerprints" of coral reef taxa and how they are diagnostic of healthy reef functioning over space and time. All organisms emit distinct volatile gases via physiological fine-tuning and signalling as their environments change. Whilst coral reef taxa and coral reefs are hotspots for volatile gas emissions, which gases are produced, when and why, is entirely unexplored.

This Project aims to uncover volatile gas "fingerprints" of coral reef taxa and how they are diagnostic of healthy reef functioning over space and time. All organisms emit distinct volatile gases via physiological fine-tuning and signalling as their environments change. Whilst coral reef taxa and coral reefs are hotspots for volatile gas emissions, which gases are produced, when and why, is entirely unexplored. This project unites a multidisciplinary team of experts to, for the first time, couple volatile gas assessment, metabolic physiology and functional genomics techniques to transform understanding of how key volatile gases underpin coral resilience to stress and disease, which is essential to improve coral reef ecosystem management.Read moreRead less

Summary
Elemental diagnostic of coral resilience to future reef climates. This project aims to integrate elemental stoichiometry, bio-elemental imaging and metabolomics to develop a common ‘elemental currency’ as an entirely new diagnostic of coral fitness. Coral reefs generate invaluable ecosystem services, but are on the verge of global collapse. Efforts to resolve coral traits that promote ecological resilience have been unable to integrate biological and environmental complexities of reef systems in ....Elemental diagnostic of coral resilience to future reef climates. This project aims to integrate elemental stoichiometry, bio-elemental imaging and metabolomics to develop a common ‘elemental currency’ as an entirely new diagnostic of coral fitness. Coral reefs generate invaluable ecosystem services, but are on the verge of global collapse. Efforts to resolve coral traits that promote ecological resilience have been unable to integrate biological and environmental complexities of reef systems into a unifying diagnostic of reef health. Natural extremes will provide the platform to identify key metabolic traits vital for future survival, to establish adaptive elemental signatures that can scale from organism to ecosystem. The project is expected to enhance capacity of marine managers and reef stakeholders to effectively manage and safeguard Australia’s reefs and the cultural and ecosystems.Read moreRead less
Factors controlling marine food webs: consumer vs. nutrient limitation of mobile invertebrates and algae. An understanding of the strength of interactions in marine food webs is crucial to predicting change in coastal habitats due to human activities. The outcomes of this research will indicate the relative importance of changes in nutrient inputs from terrestrial runoff (eutrophication) and predation pressures (via overfishing) - both of which may strongly affect the structure of marine habitat ....Factors controlling marine food webs: consumer vs. nutrient limitation of mobile invertebrates and algae. An understanding of the strength of interactions in marine food webs is crucial to predicting change in coastal habitats due to human activities. The outcomes of this research will indicate the relative importance of changes in nutrient inputs from terrestrial runoff (eutrophication) and predation pressures (via overfishing) - both of which may strongly affect the structure of marine habitats - on an extremely abundant and diverse component of coastal marine habitats.Read moreRead less
Boxing clever: artificial nest boxes as a conservation and research tool. Saving endangered species increasingly requires proactive management. This project presents an innovative and practical solution to save an iconic Australian species, while also providing the scientific foundation for the development of a novel Australian-based commercial product that will be used to protect and restore Australian biodiversity.
Bioinvasions: the interactive effects of propagule pressure and pollution. The successful establishment of species outside their native range is an increasingly frequent occurrence and can cause reductions in biodiversity and ecosystem disruption. Bioinvasions may also cause public health risks and damage to agriculture and fisheries. Nowhere is the accelerating pace of bioinvasions more dramatic than in ports and harbours. This project will determine the effects of pollution on invasion in a ma ....Bioinvasions: the interactive effects of propagule pressure and pollution. The successful establishment of species outside their native range is an increasingly frequent occurrence and can cause reductions in biodiversity and ecosystem disruption. Bioinvasions may also cause public health risks and damage to agriculture and fisheries. Nowhere is the accelerating pace of bioinvasions more dramatic than in ports and harbours. This project will determine the effects of pollution on invasion in a marine system. This project is in the national interest because it will identify mechanisms through which the invasion of exotic species are encouraged and assist in the identification and prioritisation of effective management strategies to prevent invasion.Read moreRead less
Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional en ....Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional endemism or key roles in dispersal of larvae. The ecological efficacy of the temperate Australian MPA network will be assessed through analysis of long-term ecological datasets and further development of a novel 'remote sensing' methodology, whereby surveys are undertaken by volunteer divers across much greater spatial and temporal scales than could be studied by dedicated scientific dive teams.Read moreRead less

The European shore crab has the potential to undermine the productivity of Australia's estuaries and devastate our shellfish industries, worth over $50 million p.a. This project will provide estuarine managers with the data urgently needed to prevent spread of this pest species. In doing so, it will help to ensure the future prosperity of our seafood industries and the sustainability of our unique coastal biodiversity. The outcomes of this project will be applicable to the management of many of the > 200 introduced marine species already present within our coastal waters. Importantly, the project will also contribute to research training in new techniques to protect Australia from future pest invasions.Read moreRead less
Testing the waters: impacts of contaminants on ecosystem structure and function in urban waterways. To ensure that people can swim, catch fish and enjoy the beauty of urban waterways we need to be able to predict the effects of more than one stressor at a time. This project will determine how nutrients and metals affect our waterways. Findings will help prioritise management actions that protect biodiversity and human uses of these systems.
Dynamic networks in a patchy landscape: will species interactions adjust to increased climatic extremes? This project addresses pressing questions on how increased climatic extremes will affect species diversity in arid Australia, building on the longest ecological dataset available for the continent's vast but fragile inland landscapes.

This project addresses pressing questions on how increased climatic extremes will affect species diversity in arid Australia, building on the longest ecological dataset available for the continent's vast but fragile inland landscapes. Our tests of key ideas about strong interactions among species, their role in building resilient communities and conserving biodiversity, will generate considerable international interest, while our focus on interactions of species at water sources will address knowledge gaps to inform best practice in managing converted pastoral lands. The results will contribute to retaining healthy functioning ecosystems, and the vital production systems they support, as the global climate changes.Read moreRead less
