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
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
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.

The proposers have an extensive background in these areas.
X-ray and neutron scattering techniques, developed by us, allow the interfacial structure of the surfactant to be found and the intellectual "loop" closed in the design process. Preliminary screening will be done using the surface balance and bulk emulsion synthesis.Read moreRead less
High Internal Phase Emulsions - Structure and Rheology Control. Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mes ....High Internal Phase Emulsions - Structure and Rheology Control. Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mesoscale structure in emulsion formulation, as well as the rheology and stability of emulsion preparations. To do this we plan to use mixed surfactant systems and to study intersurfactant synergic effects on the structure and fluidity of the interfacial material. We believe that the proposed work is unique and that the outcomes will be scientifically novel and also valuable for Australian industry.Read moreRead less
Optimising seasonal decisions for environmental water use. This project will develop a tool to optimise the use of environmental water, drawing on seasonal forecasts of streamflow and water price, and predicted ecological responses to changing flows. This tool will strengthen the effectiveness of the government organisations responsible for managing Australia's environmental water reserves.
Genomics for persistence of Australian freshwater fish. Biodiversity faces an unpredictable cocktail of impacts and global environmental change, against which the best insurance is genetic diversity. We will develop genomic measures of ecological-genetic functions and evolutionary potential for managing Australian freshwater fish.
Upscaling genetic management of wildlife populations. Earth’s biodiversity is in crisis: many species are threatened with extinction and need our help. Genetic management helps to stop extinctions and promotes the health and continued existence of our wildlife. This project aims to understand how to use genome science to support preservation of four endangered species in changing climates and apply these learnings to help other species to survive and thrive.

Genetic management helps to stop extinctions and promotes the health and continued existence of our wildlife. This project aims to understand how to use genome science to support preservation of four endangered species in changing climates and apply these learnings to help other species to survive and thrive. Anticipated outcomes include innovative approaches to aid conservation decision-making, automated analyses of genome data, and improved conservation training. The expected benefits include larger, healthier populations of four species, new ways of saving other species, and the provision of important resources for conservation managers.Read moreRead less
Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This ....Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This study aims to develop sophisticated Assisted Reproductive Technologies (ART) to enhance the propagation and genetic management of endangered Australian frog species. ART is a powerful new approach to ex situ conservation that, if integrated into existing captive breeding programs, will ensure the preservation of Australia’s unique amphibian biodiversity.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.
Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences.
