New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ec ....New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ecogenomics offers a way to rapidly assess the composition of an ecological community. These techniques offer great promise, but they must be cross-validated against existing methods to derive the best ’toolbox’. Working with Melbourne Water and CSIRO the investigators aim to do this using demonstration estuaries in Victoria.Read moreRead less

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
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
Environmentally-friendly strategies for shoreline protection in lakes. Most current approaches to shoreline protection involve the use of ecologically damaging hard structures. Nature-based alternatives are increasingly adopted, but often without scientific evidence that they are environmentally-friendly. With rising sea-levels, the need for coastal protection will increase, so it is essential that we develop ecologically sustainable approaches to shoreline protection. The aim of this study is ....Environmentally-friendly strategies for shoreline protection in lakes. Most current approaches to shoreline protection involve the use of ecologically damaging hard structures. Nature-based alternatives are increasingly adopted, but often without scientific evidence that they are environmentally-friendly. With rising sea-levels, the need for coastal protection will increase, so it is essential that we develop ecologically sustainable approaches to shoreline protection. The aim of this study is to assess changes to biodiversity and ecosystem functions associated with different protection strategies. The research outcomes will be an understanding of the broad ecological impacts from these approaches and will provide the basis for ecologically sustainable shoreline protection in coastal lakes and lagoons.Read moreRead less
Predicting interactive effects of multiple stressors on marine ecosystems. This project aims to create an innovative model to predict how multiple stressors interact to affect marine ecosystems across large spatial scales. The interactive effects of multiple stressors are poorly quantified in the marine environment, and natural resource managers are not able to confidently incorporate these complex interactions into prioritising management efforts in space and time. The project intends to devel ....Predicting interactive effects of multiple stressors on marine ecosystems. This project aims to create an innovative model to predict how multiple stressors interact to affect marine ecosystems across large spatial scales. The interactive effects of multiple stressors are poorly quantified in the marine environment, and natural resource managers are not able to confidently incorporate these complex interactions into prioritising management efforts in space and time. The project intends to develop models that will predict, a-priori, the type of interactions that may occur. This should enable ecosystem managers to better prioritise actions to more effectively conserve valuable and threatened marine ecosystems.Read moreRead less

The role of vegetated foreshores in stabilising Australia's shorelines. This project aims to improve Australia's capacity to predict shoreline position with sea level rise, identify the role of vegetation in foreshore stabilisation and determine thresholds for shoreline retreat by quantifying the links between biological, geomorphological and sedimentary processes and shoreline position. Sea level rise and potential increases in storminess are predicted to lead to severe impacts and there is an ....The role of vegetated foreshores in stabilising Australia's shorelines. This project aims to improve Australia's capacity to predict shoreline position with sea level rise, identify the role of vegetation in foreshore stabilisation and determine thresholds for shoreline retreat by quantifying the links between biological, geomorphological and sedimentary processes and shoreline position. Sea level rise and potential increases in storminess are predicted to lead to severe impacts and there is an immediate and critical need to understand and accurately predict the functioning, dynamics, and distribution of Australia's coastal zones. Expected outcomes of this interdisciplinary project include an integrated modelling framework crucial for planning and management of sea level rise responses in Australia.Read moreRead less
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure.

This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less
Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative ....Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative that could be incorporated into DTA programs if their ecological relevance can be demonstrated. This project will develop and validate a new and internationally significant suite of in vitro bioassays for incorporation into DTA programs, leading to more ethical, cost effective and improved environmental protection.Read moreRead less
