The proposed research will provide valuable information about the physiological functioning of trees in northern Australia. Experiments will elucidate mechanisms that can result in variation in water-use efficiency among different tree species. Such a mechanistic understanding will have multiple benefits: (1) results will be able to be incorporated into process-based models of carbon and water cycling in the north-Australian landscape; (2) they will provide valuable information for land managers interested in optimizing both plant biomass production and water resource management; and (3) they will provide a critical test of proxy methods for identifying high water-use efficiency in taxonomically diverse tree species.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

Plant species vary widely in quantitative functional traits. Global datasets about functional variation are emerging, with Australian and NZ leadership. A network would be supported in both Australia and NZ and with strong links elsewhere. It would target seven ambitious but achievable research developments. Each of them demands intensive conversation between separate disciplines. Networking across all seven strands will create a broader linkage, spanning across palaeobiology, ecosystem function, vegetation structure, global change, ecophysiology, phylogeny, genomics, ecoinformatics and evolutionary theory.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

Synthesising prior information for ecological research and management. While using existing information to design studies and compare results, ecologists rarely use existing information in their analyses. We will combine the results of previous ecological studies to summarise the existing information. We will test how well the traits of plants and animals can be predicted from previous research, and the benefit of this existing information for environmental management. By taking advantage of the ....Synthesising prior information for ecological research and management. While using existing information to design studies and compare results, ecologists rarely use existing information in their analyses. We will combine the results of previous ecological studies to summarise the existing information. We will test how well the traits of plants and animals can be predicted from previous research, and the benefit of this existing information for environmental management. By taking advantage of the wealth of previous ecological research, our project can save time and money for ecological research by scientists and environmental management by federal and state agencies. This will fundamentally change the way that ecology is conducted.Read moreRead less

Biodiversity loss in the savannas indicates unsustainable management. This research will enhance our abilities to effectively manage Australia's tropical savannas, as well as contributing to several State and Territory, Commonwealth and international obligations to maintain biodiversity. Understanding the processes underlying current declines will also make the effects of future management or environment changes easier to predict. Retaining threatened species can benefit remote and regional communities through tourism, and also through the extra employment required to implement the management prescriptions that will be developed from this research.Read moreRead less
How will Eucalypt tree architecture and growth adapt to future atmospheric CO2 and drought? This work is fundamental to understanding how growth and water use by Australia's forests will be modified in the future by global change. The changes in tree leaf area and canopy structure that we seek to understand will determine forest responses to increasing atmospheric CO2 and drought.

This work is fundamental to understanding how growth and water use by Australia's forests will be modified in the future by global change. The changes in tree leaf area and canopy structure that we seek to understand will determine forest responses to increasing atmospheric CO2 and drought. It is essential to study these changes on Australian species, because they differ from forest species elsewhere in having been largely shaped by water availability. This fundamental work will flow into predictions of future forest growth and water use in Australia, with consequences for land and water resource management as well as forestry.Read moreRead less
