The researchers will integrate studies of zooplankton biodiversity from the tropics to the Southern Ocean with an optical plankton counter to quickly measure zooplankton size and approximate shape. This new technology, together with a resurgence in collaborative marine science through the Integrated Marine Observing System and the Sydney Institute of Marine Science, will enable Australian researchers to understand changes in the plankton in freshwater or in estuaries, as well as in the East Australian Current. This current has already strengthened and is predicted to be the area of greatest warming in the Southern Hemisphere. The response of plankton communities to these changes will have profound effects on Australian fisheries and livelihoods.Read moreRead less
Trophic associations involving fish and crustaceans in coastal saltmarsh. Coastal saltmarsh is an endangered ecological community utilised by a diverse assemblage of fish during spring tides. Little attempt has been made to determine why fish visit saltmarsh, or what contribution saltmarsh makes to the diet of fish. This study combines gut analysis with novel approaches involving stable isotopes and radioactive markers to determine trophic interactions between fish and permanent members of the s ....Trophic associations involving fish and crustaceans in coastal saltmarsh. Coastal saltmarsh is an endangered ecological community utilised by a diverse assemblage of fish during spring tides. Little attempt has been made to determine why fish visit saltmarsh, or what contribution saltmarsh makes to the diet of fish. This study combines gut analysis with novel approaches involving stable isotopes and radioactive markers to determine trophic interactions between fish and permanent members of the saltmarsh fauna and flora. The project will provide coastal resource managers with quantifiable indicators of the relative significance of different saltmarsh communities to estuarine fisheries.Read moreRead less
Determining global and regional conservation priorities for biodiversity hotspots. The economic wealth of both Australia and Israel is underpinned by biological diversity - for example the remarkable biological diversity of both countries fuels multimillion-dollar tourism industries. We will devise methods to make better decisions about where to invest conservation dollars amongst the biodiversity 'hotspots' of the Mediterranean ecosystems of the world. We will create and test new theory and to ....Determining global and regional conservation priorities for biodiversity hotspots. The economic wealth of both Australia and Israel is underpinned by biological diversity - for example the remarkable biological diversity of both countries fuels multimillion-dollar tourism industries. We will devise methods to make better decisions about where to invest conservation dollars amongst the biodiversity 'hotspots' of the Mediterranean ecosystems of the world. We will create and test new theory and tools for incorporating into decision making the effect of processes such as climate change and invasion by alien species, which will help reduce the huge detrimental impacts on social, economic, health and human-well being. We will share the results of our work with decision makers and with the public.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.
The importance of sediment denitrification in the nitrogen budget of the inshore wet tropics section of the Great Barrier Reef Lagoon. The Great Barrier Reef (GBR) is a World Heritage Area that has significant ecological, economical and social values for the Australian (world) community. Nutrient over-enrichment (eutrophication) associated with runoff from adjacent catchments is a major threat to the GBR. This study will quantify what proportion of the terrestrial nitrogen load delivered to the ....The importance of sediment denitrification in the nitrogen budget of the inshore wet tropics section of the Great Barrier Reef Lagoon. The Great Barrier Reef (GBR) is a World Heritage Area that has significant ecological, economical and social values for the Australian (world) community. Nutrient over-enrichment (eutrophication) associated with runoff from adjacent catchments is a major threat to the GBR. This study will quantify what proportion of the terrestrial nitrogen load delivered to the inshore wet tropics section of the Great Barrier Reef Lagoon is removed through sediment denitrification. Critical information for understanding the process of eutrophication in the GBR Lagoon that will be used by our Industry Partner in the management, rehabilitation and protection of the GBR.Read moreRead less

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
Do marine reserve networks work? Larval connectivity, sustainable harvesting and ecological resilience. The Great Barrier Reef is a globally iconic marine ecosystem and benefits from the world's largest network of no-take reserves. While we know reserves contain more and bigger fish, several key questions about how reserves contribute to sustainable harvesting, protecting biodiversity and resisting climate change remain unanswered. Answers depend on a new understanding of the degree to which fis ....Do marine reserve networks work? Larval connectivity, sustainable harvesting and ecological resilience. The Great Barrier Reef is a globally iconic marine ecosystem and benefits from the world's largest network of no-take reserves. While we know reserves contain more and bigger fish, several key questions about how reserves contribute to sustainable harvesting, protecting biodiversity and resisting climate change remain unanswered. Answers depend on a new understanding of the degree to which fish population on different reefs are connected, and whether or not reserve networks help sustain these linkages. This project will use new technologies to measure the transport of fish larvae between reefs, to assess strengths and weaknesses of the reserve network, and examine ways to improve species protection and sustainable harvesting in a changing climate.Read moreRead less
