The effect of catchment revegetation on waterways. The effect of catchment revegetation on waterways. This project will examine the forms, transformations and fate of dissolved organic matter (DOM) in aquatic ecosystems and the link to human health with water treatment. Catchment revegetation is a management tool used to reduce excessive nutrient loads to waterways, which in turn causes poor water quality. However, catchment revegetation also produces DOM.

This project will examine the forms, transformations and fate of dissolved organic matter (DOM) in aquatic ecosystems and the link to human health with water treatment. Catchment revegetation is a management tool used to reduce excessive nutrient loads to waterways, which in turn causes poor water quality. However, catchment revegetation also produces DOM. DOM is typically poorly characterised and its effect on ecosystem health unclear. DOM also reacts with chlorine in water treatment plants to form disinfection by-products that affect human health. This research is expected to provide important new information to guide future catchment restoration efforts.Read moreRead less
How effective are environmental flows? Novel approaches for monitoring and assessing ecological responses to large-scale flow alteration. Australia has begun a multi-billion dollar program to return water to stressed rivers as environmental flows. However, during times of unprecedented water scarcity, such an investment in the environment can be controversial because the ecological benefits of released water are mostly poorly understood. This project will demonstrate the effectiveness of environ ....How effective are environmental flows? Novel approaches for monitoring and assessing ecological responses to large-scale flow alteration. Australia has begun a multi-billion dollar program to return water to stressed rivers as environmental flows. However, during times of unprecedented water scarcity, such an investment in the environment can be controversial because the ecological benefits of released water are mostly poorly understood. This project will demonstrate the effectiveness of environmental flows, and promote greater understanding of the links between flow patterns and river health. The project will build upon existing knowledge to create a sound framework for planning, monitoring, and evaluation of environmental watering decisions across regional Australia, greatly improving our ability to sustainably manage rivers into the future.Read moreRead less
Forecasting fish resilience to environmental change in northern Australia. This project aims to use a traits-based modelling framework, incorporating variability both within and between species, to forecast the resilience of freshwater fishes in northern Australia to impending environmental change. While northern Australian rivers are among the most pristine and productive on earth, they face profound change due to human activity. Emerging evidence suggests that flexibility in functional traits ....Forecasting fish resilience to environmental change in northern Australia. This project aims to use a traits-based modelling framework, incorporating variability both within and between species, to forecast the resilience of freshwater fishes in northern Australia to impending environmental change. While northern Australian rivers are among the most pristine and productive on earth, they face profound change due to human activity. Emerging evidence suggests that flexibility in functional traits (e.g. life history, physiology, behaviour, diet) may result in resilience to environmental change. This project aims to provide decision-makers with essential information and new tools to underpin future planning and resource management.Read moreRead less
Resilience of lake ecosystems to water-level manipulation. Which lakes recover from fluctuations in water level and which do not? Manipulations of water levels in lakes will need to intensify as droughts become more frequent. This project will develop robust ways of forecasting how lakes will respond to changes in manipulations of water levels, to minimise extinctions and maintain aesthetics and water quality.
