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

It is very difficult to locate items that have been buried underground or to find out their condition without digging them up. There are a number of situations involving leaking underground chemical storage tanks, and pipelines together with improperly disposed of chemical containers where chemical leaks can pose dangers to the environment and human health. This project aims to develop a robotic system that can burrow through the ground and home in on sources of leaking chemicals. Such a system could pinpoint the sources of leaks without requiring extensive excavations.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
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. Intertidal/shallow subtidal sediments are the most extensive and productive (biologically and economically) coastal ....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. 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
THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. ....THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES.

Water reuse will become a major option to meet increasing water demand in Australia. However, the presence of endocrine disrupting compounds (EDCs) in wastewater has been identified as a potential impediment for this practice. This project will use a combination of effects-based biological methods based on different levels of biological organisation, and chemical analysis to assess the efficacy of an advanced tertiary sewage treatment plant (ATSTP) to remove EDCs. The results will provide insights on 1. effects of mixtures of EDCs; 2. characterisation of risks of reuse of treated effluent; 3. optimisation of effluent treatment technologies to ensure industry competitiveness; and 4. developing sustainable plans to meet future water demand.Read moreRead less
