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
Resolving the geochemistry of coastal floodplain blackwaters. Deoxygenated dead zones are a rapidly growing global crisis in coastal areas. A major cause of dead zones in our estuaries is the formation and release of blackwaters from coastal wetlands. This project will provide the knowledge necessary to manage blackwaters in these wetlands and to greatly improve the health and sustainability of our estuaries.
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.

Summary
From sink to source: does microbial priming of degraded seagrasses contribute to global warming? Australian seagrasses are among the planet's most effective natural systems for removing greenhouse gases; but, if degraded, they could leak stored carbon and accelerate global warming. This project will test the emerging paradigm that microbes control carbon leakage, thereby providing information to ensure that seagrass carbon remains locked away.
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
Assessing fish connectivity across highly-modified seascapes. This project aims to quantify the effects of large-scale infrastructure on fish connectivity and populations by advancing our understanding of critical ecological processes within these modified coastal seascapes. The project expects to generate new knowledge in the area of fish seascape ecology and management using an innovative approach which considers all life history stages within a metapopulation modelling context. Expected outco ....Assessing fish connectivity across highly-modified seascapes. This project aims to quantify the effects of large-scale infrastructure on fish connectivity and populations by advancing our understanding of critical ecological processes within these modified coastal seascapes. The project expects to generate new knowledge in the area of fish seascape ecology and management using an innovative approach which considers all life history stages within a metapopulation modelling context. Expected outcomes of this project include the development of an integrated modelling approaches to better predict the effects of habitat modifications. This should provide significant benefits by allowing assessment of development and management actions before they take place, supporting long-term planning.Read moreRead less
Bioinvasions: the interactive effects of propagule pressure and pollution. The successful establishment of species outside their native range is an increasingly frequent occurrence and can cause reductions in biodiversity and ecosystem disruption. Bioinvasions may also cause public health risks and damage to agriculture and fisheries. Nowhere is the accelerating pace of bioinvasions more dramatic than in ports and harbours. This project will determine the effects of pollution on invasion in a ma ....Bioinvasions: the interactive effects of propagule pressure and pollution. The successful establishment of species outside their native range is an increasingly frequent occurrence and can cause reductions in biodiversity and ecosystem disruption. Bioinvasions may also cause public health risks and damage to agriculture and fisheries. Nowhere is the accelerating pace of bioinvasions more dramatic than in ports and harbours. This project will determine the effects of pollution on invasion in a marine system. This project is in the national interest because it will identify mechanisms through which the invasion of exotic species are encouraged and assist in the identification and prioritisation of effective management strategies to prevent invasion.Read moreRead less
Do pollution events facilitate biotic invasion in marine systems? This project aims to determine whether pollution affects the biological resistance of assemblages to invasion. The discharge of toxicants into coastal waters is an increasingly important source of disturbance that has the potential to make marine assemblages more susceptible to biotic invasion. The project will determine if pollution events facilitate the colonisation, persistence and spread of non-native species and how initial a ....Do pollution events facilitate biotic invasion in marine systems? This project aims to determine whether pollution affects the biological resistance of assemblages to invasion. The discharge of toxicants into coastal waters is an increasingly important source of disturbance that has the potential to make marine assemblages more susceptible to biotic invasion. The project will determine if pollution events facilitate the colonisation, persistence and spread of non-native species and how initial assemblage diversity modifies this response. The generality of several important ecological hypotheses developed in plant communities are tested in marine systems for the first time and extended to include the role of toxic disturbances.Read moreRead less
