Predicting biodiversity distribution on the Antarctic continental shelf. This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the pr ....Predicting biodiversity distribution on the Antarctic continental shelf. This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the present and future redistribution of surface primary production to the seafloor, and will enable calculating the amount of atmospheric carbon captured and stored at the seafloor. The maps will be at an unprecedented resolution of around 2 kilometres, and be invaluable tools underpinning policy, management and future science.Read moreRead less

This project aims to greatly improve the cost-effectiveness of actions to protect and restore shallow subtidal marine habitats by quantifying the severity and distribution of recent human impacts. Environmental change will be quantified as the difference between contemporary and historical assemblages encompassing thousands of invertebrate species, and by reading historical chronicles coded by mollusc shells layered in sediments. The roles of different stressors (warming, dredging, eutrophication, introduced species, sediment runoff) will be distinguished. Expected outcomes include continental-scale understanding of factors that facilitate ecosystem decline and recovery, and of sites and species traits most affected by ongoing threats.Read moreRead less

When and where are temperate reef communities vulnerable to ocean warming? This project will test in the laboratory and the field, when and where ocean warming will exceed the thermal limits of marine species and why certain species show greater sensitivity to warming temperatures than others. This project expects to generate robust estimates about how temperature sensitivity varies between populations across species’ ranges and identify the ecological implications for habitat loss in areas wher ....When and where are temperate reef communities vulnerable to ocean warming? This project will test in the laboratory and the field, when and where ocean warming will exceed the thermal limits of marine species and why certain species show greater sensitivity to warming temperatures than others. This project expects to generate robust estimates about how temperature sensitivity varies between populations across species’ ranges and identify the ecological implications for habitat loss in areas where thermal limits differ between key species. Expected outcomes include an enhanced capacity to detect when and where vulnerability hotspots will emerge that could jeopardise the immense social, ecological, and economic value of Australia’s temperate reefs, next to which 70% of Australians live, along 8,000 km of coastline.Read moreRead less

The scarcity of iron in the Southern Ocean limits biological productivity and carbon uptake. There is currently very little Information on zooplankton iron content, yet available data points to high variability. This variability is leading to poor predictive outcomes for models of Southern Ocean iron and carbon cycling. Our project addresses this knowledge gap by quantifying zooplankton iron content and examining its biogeochemical and ecological impact on Southern Ocean productivity. Developing an understanding of how iron is cycled through zooplankton will provide significant benefits including improved global models used to quantify current and future patterns of ocean productivity critical for environmental and economic predictions.Read moreRead less
