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
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
Linking flow, nutrients, seagrass and fish: an integrated approach to estuary management. Estuaries are iconic recreational areas providing both ecological habitat and millions of dollars in revenue to the tourism and fisheries industries. How estuaries respond to human pressures is highly variable with some such as the Gippsland Lakes succumbing to algal blooms, whilst other heavily nutrient laden systems such as the Werribee Estuary support extremely high fish populations. This project aims to ....Linking flow, nutrients, seagrass and fish: an integrated approach to estuary management. Estuaries are iconic recreational areas providing both ecological habitat and millions of dollars in revenue to the tourism and fisheries industries. How estuaries respond to human pressures is highly variable with some such as the Gippsland Lakes succumbing to algal blooms, whilst other heavily nutrient laden systems such as the Werribee Estuary support extremely high fish populations. This project aims to lead to an understanding of the links between freshwater flow, blue-green algal blooms, and recruitment of a key fishery species, black bream. The outcome of the project aims to give catchment managers greater confidence in setting levels of environmental flows that will both support fish populations but also mitigate against algal blooms.Read moreRead less
Ecological valuation tools to protect seagrass during coastal development. Ecological valuation tools to protect seagrass during coastal development. Focussing on differences between shallow and deep seagrasses in the Great Barrier Reef, this project aims to develop a spatial valuation tool so resource managers and policy makers can minimise the effect of port development on seagrass ecosystems.

Ecological valuation tools to protect seagrass during coastal development. Focussing on differences between shallow and deep seagrasses in the Great Barrier Reef, this project aims to develop a spatial valuation tool so resource managers and policy makers can minimise the effect of port development on seagrass ecosystems. Seagrasses provide ecosystem services (fisheries, nutrient cycling, primary productivity) worth trillions of dollars, but coastal development threatens this capacity. Resource managers lack accurate information about their potential effect and mitigation measures. Anticipated outcomes are protection of key marine environment and World Heritage Assets, and benefits to Australia’s economy through maintenance of ecosystem services and reduced risk associated with development.Read moreRead less
Sustaining intensive agriculture through droughts and floods. This project aims to develop state-of-the-art conceptual and numerical models of river-soil-groundwater interactions to address complex and persistent questions on water sustainability in the Lower Burdekin Delta, Queensland, where groundwater pumping to irrigate sugarcane has been supplemented by artificial recharge for over 50 years.

This project aims to develop state-of-the-art conceptual and numerical models of river-soil-groundwater interactions to address complex and persistent questions on water sustainability in the Lower Burdekin Delta, Queensland, where groundwater pumping to irrigate sugarcane has been supplemented by artificial recharge for over 50 years. This project expects to deliver new knowledge of critical aquifer processes to inform the scheme operation, the largest in the country. Expected outcomes include ground-breaking management plans for the aquifer-replenishment scheme. Anticipated benefits involve balancing the needs of agriculture and the protection of pristine environments, including groundwater discharge to the Great Barrier Reef.

The role of vegetated foreshores in stabilising Australia's shorelines. This project aims to improve Australia's capacity to predict shoreline position with sea level rise, identify the role of vegetation in foreshore stabilisation and determine thresholds for shoreline retreat by quantifying the links between biological, geomorphological and sedimentary processes and shoreline position. Sea level rise and potential increases in storminess are predicted to lead to severe impacts and there is an ....The role of vegetated foreshores in stabilising Australia's shorelines. This project aims to improve Australia's capacity to predict shoreline position with sea level rise, identify the role of vegetation in foreshore stabilisation and determine thresholds for shoreline retreat by quantifying the links between biological, geomorphological and sedimentary processes and shoreline position. Sea level rise and potential increases in storminess are predicted to lead to severe impacts and there is an immediate and critical need to understand and accurately predict the functioning, dynamics, and distribution of Australia's coastal zones. Expected outcomes of this interdisciplinary project include an integrated modelling framework crucial for planning and management of sea level rise responses in Australia.Read moreRead less
Nitrous oxide and methane emissions from South East Queensland waterways and influence of wastewater discharges. Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind.

Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-off and wastewater discharges. Through an in-depth study on several rivers, estuaries and reservoirs in South East Queensland, this project will provide data to enable reliable estimation of such emissions in Australia, and deliver knowledge and tool support for the development of strategic catchment management strategies.Read moreRead less
Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma.

Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative that could be incorporated into DTA programs if their ecological relevance can be demonstrated. This project will develop and validate a new and internationally significant suite of in vitro bioassays for incorporation into DTA programs, leading to more ethical, cost effective and improved environmental protection.Read moreRead less
