This project aims to provide scientifically verified methods to avoid, intercept and redesign products that cause the most abundant type of marine plastic pollution – clothing fibres - which has increased by over 450% in 60 years. It will determine how natural and plastic fibres, clothing brands and washing machine filters, alter fibre emissions and ecological impacts. This will enable protocols to improve products and the environment, and reduce health risks that will benefit the public, government regulation and companies in designing "eco-friendly" products.Read moreRead less

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
Predicting coastal ecological futures in an era of unprecedented change. This project aims to show how we can predict the future for coastal habitats, fisheries and biodiversity, and validate the reliability of those predictions. Global change means ecosystems are rapidly changing beyond the bounds of historical data, so we can no longer extrapolate past trajectories to predict the future. Reliable predictions are needed to help managers mitigate the risks of future human activities to the envir ....Predicting coastal ecological futures in an era of unprecedented change. This project aims to show how we can predict the future for coastal habitats, fisheries and biodiversity, and validate the reliability of those predictions. Global change means ecosystems are rapidly changing beyond the bounds of historical data, so we can no longer extrapolate past trajectories to predict the future. Reliable predictions are needed to help managers mitigate the risks of future human activities to the environment. Expected outcomes are improved techniques for making predictions that can inform the adaptive management of ecosystems. This is expected to benefit the management of the coastal zone, including fisheries and habitat restoration, which will contribute to enhancing Australia’s valuable ocean economy. Read moreRead less
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.
The contribution of human/marine herbivore interactions to reef degradation. This project aims to define how interactions between human society and herbivores influence marine ecosystem structure and function. It will analyse geographic patterns from recent systematic sampling of reef communities worldwide and study fish, macro-invertebrate and meso-grazer herbivory to identify herbivores’ role in the collapse and recovery of reef ecosystems. This project will examine the match between a critica ....The contribution of human/marine herbivore interactions to reef degradation. This project aims to define how interactions between human society and herbivores influence marine ecosystem structure and function. It will analyse geographic patterns from recent systematic sampling of reef communities worldwide and study fish, macro-invertebrate and meso-grazer herbivory to identify herbivores’ role in the collapse and recovery of reef ecosystems. This project will examine the match between a critical ecosystem function and community structure across local to global scales, including the identification of non-linearities and interactions involving human effects on this process. This research is expected to safeguard marine ecosystems from collapse.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
