Trees and shrubs are widely perceived as central to solving problems of national and international significance. Seed funding is sought to facilitate establishment of a research network focused on their ability to sequester carbon and transmit water to the atmosphere. The proposed network is broadly based in plant physiology and ecology and contains a strong cross-section of leading international expertise in relevant sub-disciplines. By leveraging the huge pool of international expertise and focusing on a range of scales (from molecular to biosphere scales), this network will yield new ideas and approaches that will produce outputs and outcomes of national significance.Read moreRead less
Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major in ....Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.Read moreRead less
More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the ....More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the relationship between tree cover, carbon uptake, water yield and biodiversity. The outcomes will allow government agencies, landowners and carbon farming groups to better evaluate the effects of different landscape planning options and contribute to effective long-term planning for multiple goals.Read moreRead less
Molecular biosignatures for isolating pollution problems in aquatic ecosystems using macroinvertebrate bioindicators. Aquatic ecosystems are under increasing threat by human activities. This has been further exacerbated by drought and climate change. In the future, understanding the major factors impairing aquatic ecosystems will be a vital part of sustaining water resources. This project develops new molecular tools to better monitor and assess aquatic pollution. We will develop a new high-tech ....Molecular biosignatures for isolating pollution problems in aquatic ecosystems using macroinvertebrate bioindicators. Aquatic ecosystems are under increasing threat by human activities. This has been further exacerbated by drought and climate change. In the future, understanding the major factors impairing aquatic ecosystems will be a vital part of sustaining water resources. This project develops new molecular tools to better monitor and assess aquatic pollution. We will develop a new high-tech deoxyribonucleic acid (DNA) approach to identify insect indicator species and combine this with a field-based microcosm method that uses local aquatic insects to isolate pollution effects from other impacts. This proposal will facilitate fast identification of pollution problems and provide the water industry with an innovative means to assess pollution and monitor remedial actions.Read moreRead less
Sustainable futures of Australian temperate forests: An investigation of coupled carbon, water and energy exchanges from hourly to centennial timescales. Australia's forests are a critical natural resource that must be sustainably managed. We will determine the uptake/release of carbon from old growth and regrowth forests and assess the water budgets of the Melbourne water catchment. We aim to understand the current cycles of carbon, water and energy and how these may change over time (hours to ....Sustainable futures of Australian temperate forests: An investigation of coupled carbon, water and energy exchanges from hourly to centennial timescales. Australia's forests are a critical natural resource that must be sustainably managed. We will determine the uptake/release of carbon from old growth and regrowth forests and assess the water budgets of the Melbourne water catchment. We aim to understand the current cycles of carbon, water and energy and how these may change over time (hours to centuries). We will integrate our observations with state-of-the-art models to improve our predictions of how forests will respond to change. This will aid our management of forests and forested catchments to ensure sustainable and viable water resources and optimise carbon sequestration.Read moreRead less
Cellular automata model of forest stands to predict size-class distribution and survival. Existing forest growth models predict well stand level processes such as growth. However, they provide little information on forest structure and how this affects commercial forest products, risks of growing plantations and stand dynamics that determine carbon sequestration and water-use and result in age-related decline in productivity and self-thinning. By using newly developed technology to quantify in ....Cellular automata model of forest stands to predict size-class distribution and survival. Existing forest growth models predict well stand level processes such as growth. However, they provide little information on forest structure and how this affects commercial forest products, risks of growing plantations and stand dynamics that determine carbon sequestration and water-use and result in age-related decline in productivity and self-thinning. By using newly developed technology to quantify inter-tree competition, tree level resource supply, between tree genetic differences and the importance of chance events this project will draw on complexity theory to develop an innovative model that partitions stand level production to forecast the growth and size of individual trees.Read moreRead less
Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance.

The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from escalating groundwater use. The results of this study on the evolution of two crustacean groups will provide significant biological information for management plans, facilitating conservation of mound springs communities, and helping to understand the impacts of water extraction and climate change on this unique habitat.Read moreRead less

Quantifying carbon sources and sinks and understanding the underlying processes are pre-requisites to informed policy decisions, especially as nations seek to develop strategies to manage carbon emissions and sequestration. Australia is unique because of its poor soils and high climate variability and is likely to have patterns and process of carbon that are globally different. We focus on Australia's Top-End region, but will develop tools/methods that can be applied to other important Australian hot-spots. This project will support the existing National Carbon Accounting System by providing new information on processes and spatial variability and regional budgets of carbon and water budgets that underpin our international commitments.Read moreRead less

Climate change threatens biodiversity in alpine areas of Australia. This project seeks to predict how plants, soils and small animals will respond to warming and the associated increased risk of bushfire. Our project uses chambers placed out in the field to simulate warming conditions, and measures plant growth and development, and small animal community structure within the chambers. We also assess the effects of climate change on soil processes. The information is used to evaluate the ability of alpine plants and animals to deal with climate change and to identify ways managers can help maintain biodiversity in this fragile ecosystem.
