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.

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.
Drivers of fine scale genetic spatial structuring in aquatic organisms. Understanding factors that influence genetic spatial structure of species is essential for conserving biodiversity. Movement of freshwater organisms in riverine environments is severely constrained by dendritic structure of streams, variation in aridity, and geomorphology. The project aims to test hypotheses of how these factors impact genetic patterns across east-west climatic gradients in eastern Australia. For most aquati ....Drivers of fine scale genetic spatial structuring in aquatic organisms. Understanding factors that influence genetic spatial structure of species is essential for conserving biodiversity. Movement of freshwater organisms in riverine environments is severely constrained by dendritic structure of streams, variation in aridity, and geomorphology. The project aims to test hypotheses of how these factors impact genetic patterns across east-west climatic gradients in eastern Australia. For most aquatic species, research is limited on genetic patterns across spatial scales with varying riverine dendritic structure and rarely incorporates historical data. Uncovering genetic spatial structure in aquatic ecosystems is necessary for conservation management and predicting species movements in the current changing climate.Read moreRead less

Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceu ....Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceutical company, the best means to produce and characterise nanobubbles will be investigated, as well as the conditions governing their stability. The project also aims to determine how the nanobubbles interact with surfaces in order to better control their properties and achieve a better understanding of these bubbles.Read moreRead less

Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler solvents on the way to producing cellulose-based polymers. By exploring ways to adjust the properties of celluloses for use in different applications, we can deliver potential benefits to primary producers, industries and the environment.

Designer Surfactants for Creation of Emulsion Properties. We propose new approaches to the design of surfactants for stabilising water in oil emulsions. New block copolymer surfactants may be "tailored" for head group structure and a pre-chosen hydrophilic/lipophilic balance at the oil-water interface using the Australian developed RAFT polymer synthesis method and polymeric inorganic species. The proposers have an extensive background in these areas.
