Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in ....Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in decision-making in the event of an oil spill. This project will assess the relative toxicities of a number of petroleum hydrocarbons on Australian seagrass species to provide necessary data for the development of effective management practice.Read moreRead less
Oyster biomonitor for endocrine disrupting chemicals. Endocrine disrupting chemicals (EDCs) can produce alarming detrimental impacts on the reproduction and survival of aquatic species, though little is presently known in terms of their effect and impacts on sensitive marine invertebrate species. We propose the development and validation of the first marine mollusc as a biomonitor for the detection and impact assessment of estrogenic contaminants in Australian estuarine and marine waterbodies. S ....Oyster biomonitor for endocrine disrupting chemicals. Endocrine disrupting chemicals (EDCs) can produce alarming detrimental impacts on the reproduction and survival of aquatic species, though little is presently known in terms of their effect and impacts on sensitive marine invertebrate species. We propose the development and validation of the first marine mollusc as a biomonitor for the detection and impact assessment of estrogenic contaminants in Australian estuarine and marine waterbodies. Such biomonitors will provide water management agencies with the capability to manage estrogenic effluent discharges and provide the oyster industry with a tool to prevent product contamination, ensuring the continued health and sustainability of our aquatic resources.Read moreRead less

The project's aims are to determine a) the impact of endocrine disrupting compounds (EDCs) such as contraceptive pills and detergents in sewage effluent on aquatic biota; and b) which EDCs contribute to the impact. This project will provide the first comprehensive assessment of whether EDCs are causing effects in rivers downstream of sewage treatment plants and will identify the chemicals responsible. New biological tests for detecting endocrine disruption will also be developed for research and commercial use. The findings will assist regulatory bodies and water service providers to develop appropriate legislative, management and technological strategies to minimise EDC impacts on ecosystem health.Read moreRead less
Impact of industrially based endocrine disrupting chemicals on aquatic biota. Endocrine disrupting chemicals (EDCs) are a serious threat to aquatic organisms, livestock and humans. EDCs are present in water discharged from sewage treatment plants and in leachate from contaminated land. This project will determine the impact of EDCs from contaminated landfill on aquatic animals. It will also identify the chemicals responsible for biological impact by developing new bio-assays suitable for industr ....Impact of industrially based endocrine disrupting chemicals on aquatic biota. Endocrine disrupting chemicals (EDCs) are a serious threat to aquatic organisms, livestock and humans. EDCs are present in water discharged from sewage treatment plants and in leachate from contaminated land. This project will determine the impact of EDCs from contaminated landfill on aquatic animals. It will also identify the chemicals responsible for biological impact by developing new bio-assays suitable for industrial, scientific and regulatory authority applications. This research has wide-ranging relevance and value to Australian State and Federal regulators and industries because of the ubiquity of sewage treatment plants and contaminated leachate from landfills.Read moreRead less

Environmental DNA: Integration of new methods to enhance marine management. This project aims to develop new environmental DNA (eDNA)-based methods of managing humanity’s impact on valuable marine resources. eDNA preserved in seawater provides a lens to study and monitor marine biota and ecosystems. This project will work with fisheries managers and the environmental consulting sector, and focus on sites in the Kimberley, Cocos-Keeling Islands, Fremantle and Deep-sea oil/gas sites to demonstrate the value of eDNA methods in best-practice monitoring. A multi-proxy toolkit (including eDNA) that can audit and baseline marine biota could make balancing conservation and sustainable exploitation achievable. Anticipated outcomes are improved management and monitoring of fisheries, ports and offshore oil/gas sites.Read moreRead less
Predicting the effects of desalination plant discharge in a changing ocean environment. This project will test whether changes to the ocean environment associated with climate change (a warmer and more acidic ocean) will influence the sensitivity of marine organisms to hyper-saline discharges. Novel toxicity tests will be developed using locally relevant species that will provide crucial tools for the management of coastal habitats.

This project aims to tackle a critical challenge of groundwater management – to understand and predict the impacts of declining groundwater levels. Over pumping and declining groundwater tables are a global problem, yet the effects on the ecosystems that exist within aquifers are poorly known. This project will create a world first evidence-based model of how lowering water tables affects the microbes, invertebrates (stygofauna) and ecological processes in groundwater ecosystems, and will demonstrate the consequences of such changes to groundwater quality and availability. This model will allow impacts to be reliably forecast and avoided or mitigated, vastly improving how major developments affecting groundwater are planned and implemented.Read moreRead less
