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
Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species.

Movement data will b ....Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less
Have we already lost the Australian lungfish? This project aims to use radiocarbon ageing, conservation genetics and modelling to identify threats to the long-term survival of the Australian lungfish, the world's oldest living vertebrate. This project will provide managers with a powerful tool to prioritise management interventions to ensure the conservation of the species and to pull it back from extinction.
An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses ....An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses of N, P from fertilisers will be investigated. The major outcome of this research will be effective and inexpensive procedures for reducing eutrophication due to N, P from waste water and fertilisers.Read moreRead less
A stitch in time: evidence-based strategy to keep platypus from extinction. This project aims to assess the status of the iconic platypus, identified as ‘near-threatened’ in 2014. The project’s multidisciplinary approach plans to compare regulated and unregulated rivers to investigate metapopulation structure (via physical and genetic tagging), current condition and future adaptability of the species, as well as other threats and habitat quality. The project also links vulnerability of platypus ....A stitch in time: evidence-based strategy to keep platypus from extinction. This project aims to assess the status of the iconic platypus, identified as ‘near-threatened’ in 2014. The project’s multidisciplinary approach plans to compare regulated and unregulated rivers to investigate metapopulation structure (via physical and genetic tagging), current condition and future adaptability of the species, as well as other threats and habitat quality. The project also links vulnerability of platypus populations to conservation actions that reduce extinction risk, through rigorous decision analyses. It is anticipated that the project will deliver implementable conservation actions at relevant scales.Read moreRead less
A global standard for the status of Wetlands of International Importance. The project will develop and test a new global standard for the assessment and reporting on ecological condition of internationally important wetlands, listed under the Ramsar Convention. It has four aims: establishment of a strategic adaptive management and governance framework, a meta-analysis of the 2,303 internationally listed wetlands, development of a protocol for assessment and prediction and delivering a digital re ....A global standard for the status of Wetlands of International Importance. The project will develop and test a new global standard for the assessment and reporting on ecological condition of internationally important wetlands, listed under the Ramsar Convention. It has four aims: establishment of a strategic adaptive management and governance framework, a meta-analysis of the 2,303 internationally listed wetlands, development of a protocol for assessment and prediction and delivering a digital reporting platform for effective management. The project is significant because it tackles the decline of freshwater ecosystems, by targeting the most prominent wetlands. It also assists state and national governments to meet their obligations under the Ramsar Convention and most importantly guides more effective management.Read moreRead less

This project aims to assess the risk of low rates of mixing in sub-tropical drinking water supply reservoirs, using environmental monitoring and numerical modelling. Emerging evidence suggests sub-tropical drinking water supply reservoirs could transition to low mixing states with increasing age and projected changes in global climate. While this risk is poorly understood, it could significantly affect the long-term reliability of water supply and potable water treatment costs. Addressing this knowledge gap is expected to develop effective management responses to ensure the long term sustainable use of these water resources.Read moreRead less
Imaging the world of miniature venomous arthropods. Venomous arthropods produce a myriad of biologically active peptides, with many having potential as pharmacological tools, bioinsecticides and pharmaceuticals.

Venomous arthropods produce a myriad of biologically active peptides, with many having potential as pharmacological tools, bioinsecticides and pharmaceuticals. Most studies to date have focussed on large arthropods; smaller species remain neglected due to the difficulties of venom collection. This project seeks to further advance the pioneering imaging mass spectrometry approaches the project team developed for imaging toxins in the venom glands of spiders and centipedes. By combining high-resolution matrix-assisted laser desorption ionisation imaging data with histological and transcriptomic information the project aims to provide the first detailed insights into the neglected world of miniature arthropod venoms. The approaches developed by this project aim to have wide application in the field of biology.Read moreRead less
Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less
