Genetic solution or dilution: can selective breeding future-proof oysters? This project aims to test whether the flow of beneficial genes from farmed oysters into wild oysters can make natural oyster beds and the ecological communities that they support more resilient to environmental change. Wild oysters are critical to the function of coastal ecosystems. However, wild oyster populations are threatened by environmental change in Australia and around the world. Selectively bred oysters bearing s ....Genetic solution or dilution: can selective breeding future-proof oysters? This project aims to test whether the flow of beneficial genes from farmed oysters into wild oysters can make natural oyster beds and the ecological communities that they support more resilient to environmental change. Wild oysters are critical to the function of coastal ecosystems. However, wild oyster populations are threatened by environmental change in Australia and around the world. Selectively bred oysters bearing stress resistance genotypes are now commercially farmed in many estuaries on Australia's east coast and may be used to bolster wild oyster populations. This project endeavours to develop novel genetic strategies to future-proof oysters. Thus, the outcome of this project has potential to benefit entire ecosystems that depend upon oysters.Read moreRead less

Peridinin-chlorophyll-protein complex: unravelling the unique photosynthetic apparatus of dinoflagellates in response to climatic variation. Dinoflagellates sustain the food chain. They live in coral and in ice, and also create toxic algal blooms. This project will dissect the unique photosynthetic machinery of these organisms to learn how they adapt and thrive in extreme environments. This new knowledge will predict how dinoflagellate-based ecosystems will respond to future climate change.
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
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
Identifying and creating essential habitat for rare Australian intertidal molluscs. Coastal development in Australia causes major changes to natural habitats. Obligations to conserve biodiversity are impossible without reliable information about how animals respond to habitat and how best to restore damaged habitat. Current management treats habitats as large-scale units and ignores fine-scale use of habitat by animals. This project will provide essential understanding to guide policy about coas ....Identifying and creating essential habitat for rare Australian intertidal molluscs. Coastal development in Australia causes major changes to natural habitats. Obligations to conserve biodiversity are impossible without reliable information about how animals respond to habitat and how best to restore damaged habitat. Current management treats habitats as large-scale units and ignores fine-scale use of habitat by animals. This project will provide essential understanding to guide policy about coastal conservation, by providing ecologically realistic understanding of associations between rare invertebrates and habitat. New protocols to measure these associations and success of restoration, will be applicable to any rare species in any complex habitat, increasing present capabilities for conservation.Read moreRead less
Prediction of fishery year-class-strengths from larval growth and zooplankton size structure. The abundance of young fish produced in the ocean each year is highly variable, and banks or managers need to prepare for these future changes when the fish reach market size. Therefore many nations conduct special trawl surveys of juvenile fish each year, but these are expensive, particularly when Australia has over 200 commercially harvested fish. We propose that the growth of fish larvae, recorded as ....Prediction of fishery year-class-strengths from larval growth and zooplankton size structure. The abundance of young fish produced in the ocean each year is highly variable, and banks or managers need to prepare for these future changes when the fish reach market size. Therefore many nations conduct special trawl surveys of juvenile fish each year, but these are expensive, particularly when Australia has over 200 commercially harvested fish. We propose that the growth of fish larvae, recorded as daily growth rings within the earstone of undersized fish from the fishery, could predict future abundance. We will link growth to a cost-effective assessment of their zooplankton prey in spawning areas that lead to Australia's South East Trawl region.Read moreRead less

Through a series of controlled laboratory experiments and numerical model development, this project aims to determine and quantify for the first time the role of water infiltration on sandy soil stability at actively eroding coastal sand dunes. This project expects to generate much-needed understanding of fundamental dune erosion processes using innovative instrumentation to obtain continuous measurements of wave-dune interactions, dune profile evolution, and water infiltration. Expected outcomes of this project include improved coastal engineering models to predict dune erosion under waves and increasing water levels. This should provide significant benefit to the future management of coastal assets using nature-based solutions.Read moreRead less
Understanding biodiversity by experimental analysis of links between physical, chemical and biological properties of intertidal sediments. The coastal zone accounts for 38 % of total environmental services, estimated as $12 trillion per year. Over 90 % of current development and 80 % of Australians are found within 50 km of the coast, putting enormous pressure on these habitats.

The coastal zone accounts for 38 % of total environmental services, estimated as $12 trillion per year. Over 90 % of current development and 80 % of Australians are found within 50 km of the coast, putting enormous pressure on these habitats. Intertidal/shallow subtidal sediments are the most extensive and productive (biologically and economically) coastal habitats, supporting much of Australia's unique biodiversity. Their functioning depends on complex interactions among physical, chemical and biotic processes, yet is largely unknown. Understanding these processes is crucial for coastal planning and management, to minimise habitat-loss and retain biodiversity in these important habitats.Read moreRead less
