Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
Improved biomonitoring of urban freshwater ecosystems using DNA barcodes. This project aims to provide rapid diagnostic detection of environmental change in aquatic ecosystems at reduced cost. Next-generation sequencing (NGS) can transform monitoring of aquatic ecosystems by identifying many species in multiple biological samples. This project aims to use NGS technology to identify macroinvertebrate species as biological indicators in urban freshwater ecosystems to provide more rapid, sensitive ....Improved biomonitoring of urban freshwater ecosystems using DNA barcodes. This project aims to provide rapid diagnostic detection of environmental change in aquatic ecosystems at reduced cost. Next-generation sequencing (NGS) can transform monitoring of aquatic ecosystems by identifying many species in multiple biological samples. This project aims to use NGS technology to identify macroinvertebrate species as biological indicators in urban freshwater ecosystems to provide more rapid, sensitive and cost-effective monitoring compared to traditional methods. The project uses DNA barcodes that identify species to detect species in samples processed with NGS. The project also plans to use previously collected samples to explore species diversity and detect indicator species.Read moreRead less

Summary
New technology for accurate freshwater biodiversity assessment using environmental DNA. This project will develop a new biodiversity monitoring tool for identifying freshwater fish species without their capture or observation, using environmental DNA (faeces, urine and skin cells) extracted from water samples. This new tool will be used to survey for all fish species in freshwater ecosystems in southwestern Australia, a biodiversity hotspot.
Subterranean invertebrate communities of arid zone Western Australia: diversity, assessment and food-web structure. The diverse and unique subterranean fauna associated with aquifers of the Western Australia arid zone is potentially threatened by water extraction, mining and other human impacts. This project aims to apply a powerful combination of molecular genetic analyses and compound specific isotope analyses to study, for the first time, the food web structure and source of energy of these g ....Subterranean invertebrate communities of arid zone Western Australia: diversity, assessment and food-web structure. The diverse and unique subterranean fauna associated with aquifers of the Western Australia arid zone is potentially threatened by water extraction, mining and other human impacts. This project aims to apply a powerful combination of molecular genetic analyses and compound specific isotope analyses to study, for the first time, the food web structure and source of energy of these groundwater ecosystems. The project aims to also develop novel procedures for monitoring their biodiversity using environmental DNA within the groundwater. The results will provide crucial information for the management of groundwater, and conservation of their associated ecosystems, and significantly improve the rigour of long-term environmental monitoring.Read moreRead less
Revolutionising biodiversity monitoring in freshwater ecosystems using environmental DNA. Australian biodiversity is declining at an unprecedented rate and freshwater species are particularly at risk. Effective conservation of freshwater biodiversity depends on reliable, accurate and cost-efficient monitoring techniques for assessing species communities and key environmental assets and threats. However, current techniques are inefficient, expensive and highly invasive. This project aims to utili ....Revolutionising biodiversity monitoring in freshwater ecosystems using environmental DNA. Australian biodiversity is declining at an unprecedented rate and freshwater species are particularly at risk. Effective conservation of freshwater biodiversity depends on reliable, accurate and cost-efficient monitoring techniques for assessing species communities and key environmental assets and threats. However, current techniques are inefficient, expensive and highly invasive. This project aims to utilise a novel methodology known as environmental DNA to revolutionise biodiversity surveys in freshwater environments, and aims to lead to a substantial increase in positive conservation outcomes through cost-efficient and accurate assessments of the distributions and abundances of both native and introduced species.Read moreRead less
From hazard identification to risk management. From hazard identification to risk management. This project aims to explore health risks from water- and sediment-borne bacteria to recreational users of urban rivers, using a suite of novel molecular microbiological and in-vitro assays and microbial risk assessment modelling.

This project aims to explore health risks from water- and sediment-borne bacteria to recreational users of urban rivers, using a suite of novel molecular microbiological and in-vitro assays and microbial risk assessment modelling. This project also aims to develop source tracking methods to mitigate and manage these risks. The number of bacterial-related water-borne outbreaks associated with recreational activities is rising, but waterway managers are under pressure to re-open these rivers for recreation. The project is expected to benefit urban communities by ensuring waterway managers make informed decisions about river recreation.Read moreRead less
A new-generation flood forecasting system using observations from space. Floods are dangerous and expensive, costing Australia more than any other cause of natural disaster. This project will use satellite measurements of soil moisture and rainfall along with computer models to improve the Bureau of Meteorology’s predictions of floods in rivers. Better flood forecasts will reduce costs and save lives.
Functional characterisation of contaminant-nanoparticle associations. Nanoparticles present in the environment modify the movement and toxicity of contaminants. This project targets key gaps that hinder the ability to predict the fate and behaviour of environmental contaminants; this will lead to the optimisation of legislative framework and the management/remediation of contaminated sites (for example, mine sites, landfills).
From environmental monitoring to management: extracting knowledge about environmental events from sensor data. New, high-detail sources of environmental sensor data are useless without new methods for identifying patterns and extracting knowledge from that data. This project will develop improved techniques for interacting with environmental sensor data to assist environmental scientists and manager in understand the important events that are occurring.
Predicting water quality at the catchment scale: learning from two decades of monitoring. Poor water quality affects many rivers and receiving waters such as the Great Barrier Reef and Gippsland Lakes. This project aims to use Bayesian hierarchical models of statewide water quality data to quantify the effects of a range of factors on stream water quality including climate, land use, river flow, vegetation cover, etcetera. The analysis intends to extract information from the entire data set rath ....Predicting water quality at the catchment scale: learning from two decades of monitoring. Poor water quality affects many rivers and receiving waters such as the Great Barrier Reef and Gippsland Lakes. This project aims to use Bayesian hierarchical models of statewide water quality data to quantify the effects of a range of factors on stream water quality including climate, land use, river flow, vegetation cover, etcetera. The analysis intends to extract information from the entire data set rather than concentrating on individual sites. It intends to underpin a new predictive capacity including response to land use and management changes and climatic variations based on long-term data sets, as well as a water quality prediction capability. It is intended that the models developed will jointly model a range of inter-related water quality parameters.Read moreRead less
