Origins of a biodiversity hotspot flora: diversification of the Australian Proteaceae. Why does Australia's only biodiversity hotspot, with nearly 3000 endemic plant species, occur in an area with poor soils and low rainfall? This project will analyse DNA sequences from over 1000 plant species of the Australian Proteaceae, many found only in this hotspot, to help us understand the evolutionary and ecological origins of this iconic flora.

Summary
Assessing the impact of global environmental change on the nutritional ecology of marsupial and insect folivores of Eucalyptus. Higher atmospheric carbon dioxide concentrations are predicted to alter plant nutrient and toxin content, while higher ambient temperatures may compromise the abilities of animals to metabolise plant toxins. This project will assess how climate change scenarios are likely to impact native marsupials and insects that rely on eucalypt leaves for food.

Summary
Snow, shrub and climate feedbacks: impacts of shrub expansion in the Australian alpine zone. This project aims to understand the mechanisms promoting shrub expansion in alpine areas and the consequences of a shrub-dominated landscape in terms of shrubs as hydrological mediators and as biodiversity and ecosystem modifiers. Some shrub species trap wind-blown snow, thereby facilitating seedling survival through soil insulation and increases to meltwater. However, if adaptive and plastic responses t ....Snow, shrub and climate feedbacks: impacts of shrub expansion in the Australian alpine zone. This project aims to understand the mechanisms promoting shrub expansion in alpine areas and the consequences of a shrub-dominated landscape in terms of shrubs as hydrological mediators and as biodiversity and ecosystem modifiers. Some shrub species trap wind-blown snow, thereby facilitating seedling survival through soil insulation and increases to meltwater. However, if adaptive and plastic responses to climate change allows, shrub expansion will have significant negative impacts on alpine biodiversity and ecosystem function. This project will tease apart the interacting effects of snow, recruitment and adaptation to provide models of shrub increase and determine how shrubs modify alpine ecosystem processes and upper catchment hydrology.Read moreRead less
The evolution and maintenance of specificity, mutualism and diversity in plant-soil microbe interactions. This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration prac ....The evolution and maintenance of specificity, mutualism and diversity in plant-soil microbe interactions. This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration practices. Furthermore, it will see the continued development of the Acacia-rhizobia system as a world-class model for exploring interactions between perennial legumes and microbial symbionts. The research also investigates the adaptability and potential for rapid evolution of critical elements of the soil microflora to environmental change.Read moreRead less

Summary
High-throughput sample preparation robotics to enable emerging large-scale plant genomics, metabolomics and proteomics research. Discovering and breeding plants that are best suited for new environmental conditions requires the analysis of many samples to discover the underlying genes, metabolites and proteins. The project will build two robotic instruments that will facilitate the rapid grinding and extraction of plant tissues to facilitate these discoveries across Australia.
Australian plague locust population genetics and migratory behaviour. The project will allow improved monitoring and forecasting of locusts in Australia and thereby help prevent locust outbreaks. Benefits will arise directly through greater effectiveness in reducing locust damage to crops, and indirectly to Australian rural industry generally through the economic benefits of reduced losses and locust control costs. Environmental and social benefits will also arise from reduced, better targeted u ....Australian plague locust population genetics and migratory behaviour. The project will allow improved monitoring and forecasting of locusts in Australia and thereby help prevent locust outbreaks. Benefits will arise directly through greater effectiveness in reducing locust damage to crops, and indirectly to Australian rural industry generally through the economic benefits of reduced losses and locust control costs. Environmental and social benefits will also arise from reduced, better targeted use of chemical insecticides. This in turn can produce secondary economic benefits, e.g. through enhanced growth and profitability of the organic beef industry within the main locust-outbreak area. Read moreRead less
The causes and effects of mortality in tropical Australian trees. Drought can cause the widespread death of tropical trees resulting in large emissions of carbon dioxide to the atmosphere, but predictions of tree death during drought remain rudimentary. This project will combine new data and modelling on how Australian tropical trees respond to drought to improve estimates of tree mortality risk and its impacts.
Anatomy of a biodiversity hotspot: investigating the evolutionary and ecological basis of high plant diversity in southwestern Australia. Southwestern Australia - Australia's only global biodiversity hotspot - has an exceptionally rich flora but has suffered extensive habitat loss, so many rare plants are threatened with extinction.

Southwestern Australia - Australia's only global biodiversity hotspot - has an exceptionally rich flora but has suffered extensive habitat loss, so many rare plants are threatened with extinction. Further, this region is expected to suffer severely under projected climate change scenarios, lending urgency to efforts to describe and understand the regions plant biodiversity. This project will provide the first description and analysis of an important but hitherto little-known aspect of biodiversity, the evolutionary structure of ecological communities. This will enhance our understanding of how communities are assembled, providing a stronger scientific basis for sustainable management of the southwest's biodiversity.Read moreRead less
Breeding for resistance: Diagnostic toolkit for predicting variation in plant defence compounds in Eucalyptus. Pulp and timber from plantations are important for Australia's economic and environmental future. However, we must ensure that these plantations are grown sustainably.

Pulp and timber from plantations are important for Australia's economic and environmental future. However, we must ensure that these plantations are grown sustainably. One area of concern is the current reliance on pesticides to control herbivores of plantation eucalypts. The work proposed here aims to use existing ecological findings together with early access to the genome of Eucalyptus to develop ways of using the natural resistance of Eucalyptus as an alternative to chemical pesticides. The work will also help us to understand how eucalypts produce the distinctive odours that are so characteristic of Australian landscapes.Read moreRead less

Recent advances in remote sensing are allowing us to measure the biochemical and structural properties of ecosystems with increasing accuracy. This type of information is essential for sustainable natural resource management. However, we still lack a clear understanding of this technology's capabilities and limitations for environmental decision making. This project aims to investigate key gaps in our knowledge about the extent to which modern remote sensing tools are capable of measuring landscape change and habitat quality. This collaborative research project aims to provide an unparalleled opportunity to examine these issues by combining state-of-the-art remote sensing with data from two intensively studied landscape-scale experiments.Read moreRead less
