Development of environmentally-friendly bioinsecticides for control of Australian crop pests. Insect pests cause over $3 billion of damage each year to Australian crops. Current insecticides are becoming less effective, and they often have adverse environmental impacts. This project aims to develop a new generation of environmentally-friendly insecticides that can be used to control insect pests on farms and around the home and garden.
Improving heat and drought tolerance in canola through genomic selection in Brassica rapa. This project aims to improve heat and drought tolerance in canola by identifying stress tolerance genes in the genetically diverse turnip family. An effective large-scale screening test for heat and drought tolerance will be developed and a number of heat- and drought-tolerant lines will be identified for genomic breeding and selection.
Characterisation of a major quantitative trait locus on wheat chromosome 3BL responsible for Fusarium crown rot resistance. Fusarium crown rot (FCR) is a serious wheat disease in Australia and worldwide. Our team has identified a major chromosome region controlling this disease. This project is proposing to develop DNA markers for marker assisted breeding, to understand the genetic mechanism of resistance and to identify genes responsible for resistance to the disease.
Towards improving the yield of Canola and other Brassicas during drought. One of the major problems faced by world agriculture is drought; this project should improve the yield of Canola during moderate to severe droughts. Significantly, this project includes both "traditional" non-genetically modified (GM) strategies and GM strategies to maximise the market for our drought-tolerant canola both in Australia and overseas.
Sustaining Australia's sheep industry under climate change: modelling Australia's sheep flock response to climatic and economic constraints. This project aims to provide a quantitative assessment of the impact of climate change and economic conditions on the Australian sheep industry. This will be achieved by constructing a robust dynamic model of the Australian sheep flock capable of integrating biophysical and economic constraints across regional and national scales. Using historical and proje ....Sustaining Australia's sheep industry under climate change: modelling Australia's sheep flock response to climatic and economic constraints. This project aims to provide a quantitative assessment of the impact of climate change and economic conditions on the Australian sheep industry. This will be achieved by constructing a robust dynamic model of the Australian sheep flock capable of integrating biophysical and economic constraints across regional and national scales. Using historical and projected biophysical and economic inputs it will enhance the capacity of the Australian sheep industry for strategic planning in the face of projected climate change. This capacity is being actively sought by the peak sheep industry bodies in conjunction with our industry partner the Bureau of Rural Sciences.Read moreRead less
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a nov ....Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a novel NUE technology that when transferred to plants significantly improves NUE. We will define the phenotype at the molecular, biochemical and physiological levels to maximise its adoption to other agricultural crops such as wheat, barley and maize.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.
Understanding the koala microbiome: unlocking the secrets of koala health and dietary specialisation, and successful husbandry and translocation. This project aims to discover how the composition and function of koala gastrointestinal microbial communities differ in space and time in response to the varying nutritional quality and chemical composition of koala diets. Using detailed chemical analysis, cutting edge metagenomic and bioinformatic pipelines and powerful approaches to study enzyme fun ....Understanding the koala microbiome: unlocking the secrets of koala health and dietary specialisation, and successful husbandry and translocation. This project aims to discover how the composition and function of koala gastrointestinal microbial communities differ in space and time in response to the varying nutritional quality and chemical composition of koala diets. Using detailed chemical analysis, cutting edge metagenomic and bioinformatic pipelines and powerful approaches to study enzyme functions in the koala’s gut, the investigators aims to reveal the role of microbes in detoxification of plant toxins and degradation of recalcitrant fibre fractions. The outcomes aim to facilitate the use of faecal transplants to improve digestive function for translocated and rehabilitated koalas, enhancing options for koala management and conservation.Read moreRead less
Marine urban development: how can ecology inform the design of multifunctional artificial structures? This project aims to experimentally manipulate the design of artificial structures to achieve multipurpose ecological objectives.

This project aims to experimentally manipulate the design of artificial structures to achieve multipurpose ecological objectives. Artificial structures such as buildings and roads have featured in terrestrial urban landscapes for many years, but have only more recently begun encroaching on aquatic environments. Most marine artificial structures lack the innovative design solutions required to mitigate their ecological impacts and provide essential ecosystem services such as pollution abatement. This project will investigate the efficacy of these designs with both classical measures of diversity and structure and novel measures of ecosystem function. The project aims to provide essential information to inform the design of future marine urban developments.Read moreRead less
