Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild ba ....Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild barley and identify appropriate candidate genes and their position on chromosomes for further incorporating these traits into commercial barley cultivars. This will reduce the environmental footprint of modern agricultural practices on terrestrial and aquatic ecosystems without compromising food security.Read moreRead less
Testing climatic, physiological and hydrological assumptions underpinning water yield from montane forests. Water collected in dams and reservoirs remains the mainstay water resource for Australian cities, towns and industry. Overwhelmingly, that water is collected from forested catchments where the water balance of forest stands is dominated by the amount of water used by trees. Characterising tree water use, its response to changing climatic and nocturnal conditions, and other aspects of sta ....Testing climatic, physiological and hydrological assumptions underpinning water yield from montane forests. Water collected in dams and reservoirs remains the mainstay water resource for Australian cities, towns and industry. Overwhelmingly, that water is collected from forested catchments where the water balance of forest stands is dominated by the amount of water used by trees. Characterising tree water use, its response to changing climatic and nocturnal conditions, and other aspects of stand hydrology, are crucial to our ability to predict and model future water yields. Working in the Cotter catchment near Canberra and the upper Kiewa catchment in north-east Victoria, we aim to help the agencies responsible for water and catchment management to improve the security of their forecasts of water yield and their on-ground management.

Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in ....Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in decision-making in the event of an oil spill. This project will assess the relative toxicities of a number of petroleum hydrocarbons on Australian seagrass species to provide necessary data for the development of effective management practice.Read moreRead less
Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.
Improving determinants of Australian sports talent identification and development: a multi-disciplinary approach. Sport is important to many Australians. Our sport successes enhance our national identity, generate community pride and attract mega sport events. Currently our sport talent identification and development (TID) systems have been surpassed by our international rivals who borrowed from and improved our knowledge. This project will help regain Australia's international advantage and aga ....Improving determinants of Australian sports talent identification and development: a multi-disciplinary approach. Sport is important to many Australians. Our sport successes enhance our national identity, generate community pride and attract mega sport events. Currently our sport talent identification and development (TID) systems have been surpassed by our international rivals who borrowed from and improved our knowledge. This project will help regain Australia's international advantage and again make Australian TID the international benchmark. Results will highlight the role of TID practices in improving recreational participation and maximising, attracting, developing and retaining sport talent. This will result in improved use of sports limited TID funding by providing greater understanding of factors that influence elite selection and sport development.Read moreRead less
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less
Forecasting live fuel moisture content, the on/off switch for forest fire. Dry forest fuels are a precursor of large bushfires. This research aims to develop, for the first time, a model to reliably forecast the moisture content of live fuels (e.g. the foliage and fine branches of shrubs and trees). This will be achieved by combining (i) satellite-derived estimates of live fuel moisture content, (ii) forecasts of soil moisture, and (iii) plant physiological responses to soil dryness. Forecasts o ....Forecasting live fuel moisture content, the on/off switch for forest fire. Dry forest fuels are a precursor of large bushfires. This research aims to develop, for the first time, a model to reliably forecast the moisture content of live fuels (e.g. the foliage and fine branches of shrubs and trees). This will be achieved by combining (i) satellite-derived estimates of live fuel moisture content, (ii) forecasts of soil moisture, and (iii) plant physiological responses to soil dryness. Forecasts of live fuel moisture content will deliver an early warning system of the risk of bushfires. These forecasts will also facilitate improved planning of prescribed burns: if fuels are too dry there is a risk of burns escaping, conversely, if fuels are too wet there is a risk that burns will fail to meet objectives.Read moreRead less

The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantify the interactive impact of temperature and nutrition on immune function, disease resistance and host-plant quality of plague locusts; and to explore the combined effects of temperature, habitat and Green Guard, in combination with candidate microbes or pathogens, on the behaviour and collective movement of locusts. It is anticipated that this will have implications for management and control strategies.Read moreRead less
