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
Testing the waters: impacts of contaminants on ecosystem structure and function in urban waterways. To ensure that people can swim, catch fish and enjoy the beauty of urban waterways we need to be able to predict the effects of more than one stressor at a time. This project will determine how nutrients and metals affect our waterways. Findings will help prioritise management actions that protect biodiversity and human uses of these systems.
Clothes, fibres and filters that reduce pollution by micro and nano debris. 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 t ....Clothes, fibres and filters that reduce pollution by micro and nano debris. 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
Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity a ....Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity and function of coastal seascapes is to be conserved. This project aims to use a combination of novel modelling, surveys, and large experiments to understand how threatened seagrass, fish, and sediment habitats are altered in human modified seascapes, and to assess the success of habitat restoration following the removal of boating structures.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.
Microplastic infiltration of food webs: cells to ecosystem consequences. Using trophic ecological theory as a framework, this project aims to provide the first comprehensive assessment of the fate and effects of microplastics. Plastic pollution is a persistent and increasing problem. Plastics are degraded into small particles, called microplastics, which are ingested by animals. The project aims to develop much-needed techniques to measure microplastics in biological tissue and apply these techn ....Microplastic infiltration of food webs: cells to ecosystem consequences. Using trophic ecological theory as a framework, this project aims to provide the first comprehensive assessment of the fate and effects of microplastics. Plastic pollution is a persistent and increasing problem. Plastics are degraded into small particles, called microplastics, which are ingested by animals. The project aims to develop much-needed techniques to measure microplastics in biological tissue and apply these techniques in food web studies to determine the capacity of microplastics to transfer from the environment into animals, and how microplastics move through a food web to affect biological diversity and animal health. This information will be used to complete the first risk assessment for microplastics in a major coastal habitat.Read moreRead less
Towards 2050 - managing recovery of Australia's coral reefs. The coral reefs of Australia contribute over $6 bn each year to the economy. However, the reefs of Australia, in addition to those worldwide, are threatened by coral bleaching driven by anthropogenic climate change. If we are to preserve the economic, social and ecosystem value of these environments, it is essential that we are able to better manage the recovery of reefs from bleaching events. This project will utilise a variety of mul ....Towards 2050 - managing recovery of Australia's coral reefs. The coral reefs of Australia contribute over $6 bn each year to the economy.

The proposed research will provide insight into the physiological and morphological features that control the productivity of mangrove forests across broad gradients in salinity and aridity. Central to this is this identification of plant traits that increase salt and drought tolerance, which will assist in the development of plant varieties suited to Australian conditions. The results will also contribute to development of process-based models to better predict the response of mangrove vegetation to changing climate. A deep understanding of the processes that influence the growth and survival of mangroves is of fundamental importance to sustainable fisheries and protection of wildlife reliant on coastal ecosystems.
