Toxic cyanobacterial blooms in a carbon dioxide (CO2)-rich world: assessing the impacts of global climate change. Cyanobacterial blooms in Australia cost the country over $150 million every year because of their impacts on water quality and animal and human health. The frequency, distribution and intensity of these blooms are all expected to increase worldwide as global climate change impacts increase over the next century. This project will provide much needed information of the severity of imp ....Toxic cyanobacterial blooms in a carbon dioxide (CO2)-rich world: assessing the impacts of global climate change. Cyanobacterial blooms in Australia cost the country over $150 million every year because of their impacts on water quality and animal and human health. The frequency, distribution and intensity of these blooms are all expected to increase worldwide as global climate change impacts increase over the next century. This project will provide much needed information of the severity of impacts on cyanobacteria commonly causing blooms in Australian aquatic ecosystems. This information will be important to authorities responsible for managing our precious water resources.Read moreRead less

Summary
Tuneable diode laser for field and laboratory measurement of stable isotopes of CO2. The tuneable diode laser system will facilitate projects with major environmental benefits to Australia. Projects will provide major insights into Australia's CO2 balance. This will improve our ability to predict whether ecosystems are net sources or sinks for CO2 -- information that underpins Australia's greenhouse gas balance. The tuneable diode laser system will also benefit Australia's economy via enhanci ....Tuneable diode laser for field and laboratory measurement of stable isotopes of CO2. The tuneable diode laser system will facilitate projects with major environmental benefits to Australia. Projects will provide major insights into Australia's CO2 balance. This will improve our ability to predict whether ecosystems are net sources or sinks for CO2 -- information that underpins Australia's greenhouse gas balance. The tuneable diode laser system will also benefit Australia's economy via enhancing understanding of agricultural and forest production, a key portion of our GDP. These economic benefits will stem from new knowledge about the limitations to plant growth and the water-use efficiency of plants. 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
Elevated carbon dioxide (CO2) effects on vegetation: repairing the disconnect between experiments and models. Ecosystem models are important tools used in a variety of applications, including predicting how vegetation uptake of carbon affects global climate, estimating carbon sequestration by natural and planted forests and determining water yield of catchments. Although there has been a massive investment in experiments to determine plant response to elevated carbon dioxide [CO2], ecosystem mod ....Elevated carbon dioxide (CO2) effects on vegetation: repairing the disconnect between experiments and models. Ecosystem models are important tools used in a variety of applications, including predicting how vegetation uptake of carbon affects global climate, estimating carbon sequestration by natural and planted forests and determining water yield of catchments. Although there has been a massive investment in experiments to determine plant response to elevated carbon dioxide [CO2], ecosystem models do not incorporate this body of data as well as they could. This project will use innovative methods to bridge the gap between experimental data and ecosystem models, resulting in significantly improved information for managers of Australia's natural resources into the future.Read moreRead less
