The National Representative System of Marine Protected Areas contributes directly to the protection of marine biodiversity, and to Australia's international obligations under the UN Convention on Biological Diversity. Non-indigenous species have potential to undermine native biodiversity in marine protected areas across Australia. By identifying the most effective strategies for dealing with potential incursions of non-indigenous species in Victorian marine national parks and sanctuaries, the project will make a valuable contribution to the viability of local marine ecosystems and the maintenance of biodiversity. Furthermore, it will provide a template to aid similar decision-making in other marine protected areas around the country.Read moreRead less
Theory for global biodiversity conservation. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. We will devise methods to make better decisions about where to invest conservation dollars amongst the biodiversity "hotspots" of the world and Australia to deliver environmental sustainability. We will solve the problem of how much of any environmental budget should be spent on mo ....Theory for global biodiversity conservation. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. We will devise methods to make better decisions about where to invest conservation dollars amongst the biodiversity "hotspots" of the world and Australia to deliver environmental sustainability. We will solve the problem of how much of any environmental budget should be spent on monitoring conservation actions to make better and more cost-effective decisions. We will create new theory and freely available tools for building systems of marine reserves that allow for threats like coral bleaching and hurricanes.Read moreRead less
The quality of seagrass as a dugong food resource: the importance of the effects of season and water depth. Australia has international obligations to conserve dugongs (sea cows). Dugongs rely on seagrasses for food. Knowledge of the abundance and quality of seagrasses, and how these change in response to the environment, is vital if dugong conservation is to have the necessary scientific basis. Research has focussed on intertidal seagrass as food for dugongs. However, deepwater seagrasses ....The quality of seagrass as a dugong food resource: the importance of the effects of season and water depth. Australia has international obligations to conserve dugongs (sea cows). Dugongs rely on seagrasses for food. Knowledge of the abundance and quality of seagrasses, and how these change in response to the environment, is vital if dugong conservation is to have the necessary scientific basis. Research has focussed on intertidal seagrass as food for dugongs. However, deepwater seagrasses are a mainstay of most significant dugong populations, such as the population in Hervey Bay, Queensland. This research will provide information on the effect of season and water depth on the quality of seagrasses as dugong food.Read moreRead less
Environmental management of coral reef resilience. The primary aim of this project is to provide the scientific evidence needed to effectively manage and protect reef resilience within the GBR Marine Park. We will develop and apply scientific tools for understanding the large-scale effect of multiple physical environmental stresses on coral populations. Furthermore, we will determine how fish communities influence the potential for coral reefs to remain healthy in the face of global change. Cent ....Environmental management of coral reef resilience. The primary aim of this project is to provide the scientific evidence needed to effectively manage and protect reef resilience within the GBR Marine Park. We will develop and apply scientific tools for understanding the large-scale effect of multiple physical environmental stresses on coral populations. Furthermore, we will determine how fish communities influence the potential for coral reefs to remain healthy in the face of global change. Central to this work will be an evaluation of the potential of No-Take Zones, a contemporary management tool, to promote resilience and the ability of coral reefs to cope with environmental change.Read moreRead less
Effectiveness of temperate Australian marine protected areas as tools for biodiversity conservation and informing fisheries management. The effectiveness of marine protected areas (MPAs) for biodiversity protection and informing fisheries management will be investigated at a continental scale for the first time. Communities of fishes, invertebrates and plants at >100 sites within MPAs in WA, NSW and Tasmania will be studied from prior to fisheries protection, with changes over time compared with ....Effectiveness of temperate Australian marine protected areas as tools for biodiversity conservation and informing fisheries management. The effectiveness of marine protected areas (MPAs) for biodiversity protection and informing fisheries management will be investigated at a continental scale for the first time. Communities of fishes, invertebrates and plants at >100 sites within MPAs in WA, NSW and Tasmania will be studied from prior to fisheries protection, with changes over time compared with changes at fished reference sites. This study represents a human predator exclusion experiment with a scale sufficiently large to distinguish general patterns from among site specific and species specific variability. It will provide management authorities with information crucial to determining MPA number, size and configuration.Read moreRead less
How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I prop ....How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I propose to compare the life histories and microchemical signatures in larval otoliths of endemic and closely related non-endemic reef fishes to determine the mechanisms and prevalence of self-recruitment. The results will broaden our understanding of how marine populations are replenished, information critically needed for marine conservation and resource management.Read moreRead less
Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the deve ....Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the development of better strategies to manage their impacts. The project will also build Australia's wider capacity to manage outbreaks of infectious diseases.Read moreRead less
Larval Dispersal And The Design Of Marine Reserve Networks: Benefits Within And Beyond Boundaries. Most marine organisms produce tiny offspring that are dispersed unknown distances by oceanic currents. Our present strategies to manage marine resources lack this vital piece of information. This study will apply two revolutionary techniques that finally enable us to determine how far marine larvae travel. Using the team that developed these techniques, field studies will for the first time measure ....Larval Dispersal And The Design Of Marine Reserve Networks: Benefits Within And Beyond Boundaries. Most marine organisms produce tiny offspring that are dispersed unknown distances by oceanic currents. Our present strategies to manage marine resources lack this vital piece of information. This study will apply two revolutionary techniques that finally enable us to determine how far marine larvae travel. Using the team that developed these techniques, field studies will for the first time measure both retention of fish larvae within marine protected areas and dispersal of larvae to adjacent fished areas on coral reefs. This information can be directly applied to optimize the size of reserves and their spacing in marine protected area networks.Read moreRead less

The World Heritage Great Barrier Reef sustains unique marine biota such as dugongs and turtles. High concentrations of harmful dioxins have been reported recently in dugongs. However, the impacts of these contaminants on the health of dugong and turtle populations remain unknown. This study will redress the general lack of toxicological information available for reptiles and dugongs. This includes assessments of exposure, pathways as well as toxicological responses to the compounds of concern, to provide a robust assessment of the risks associated. The outcomes will guide management policy designed to protect the environmental health of Queensland's Marine Parks.Read moreRead less

The primary national benefit will be to better safeguard biological diversity by reducing extinction risk for marine species. This will be achieved through analysis of factors affecting extinction risk, and through the development of protocols to improve the siting of marine protected areas for conservation outcomes. A more effective National Representative System of Marine Protected Areas will be achieved through decreased extinction risk and lower opportunity costs. In addition, a quantitative baseline dataset will be obtained for evaluating long-term changes in threatened marine species populations, and the effectiveness of future management actions aimed to safeguard threatened species.Read moreRead less
