Explaining forest responses to rising carbon-dioxide concentrations at stand scale using a new, simple model of plant carbon economy. Australia is undergoing large changes in [CO2] and rainfall patterns, with 20% decreases in annual rainfall across southern Australia over the past 30 years, and large increases in north-western Australia. The impacts of rising [CO2] and altered rainfall must be factored into Australia's environmental and water-catchment management strategies. The outcome of this ....Explaining forest responses to rising carbon-dioxide concentrations at stand scale using a new, simple model of plant carbon economy. Australia is undergoing large changes in [CO2] and rainfall patterns, with 20% decreases in annual rainfall across southern Australia over the past 30 years, and large increases in north-western Australia. The impacts of rising [CO2] and altered rainfall must be factored into Australia's environmental and water-catchment management strategies. The outcome of this project will be a new simplified forest model that has been validated for Australia's leading climate-change experiment on forests, the Hawkesbury Forest Experiment, which includes both CO2 and watering treatments. The model will be readily transferable to new sites and at regional scale, so it can be applied as a tool for future management of Australia's forests.Read moreRead less
Devising a methodology for the digital soil map of the world. Soil mapping is a key part of land-resource assessment for sustainable environmental management. The output will enable the use of soil data and information to give a clear understanding of the status of, and changes in, the nation's land, vegetation and water resources and implications for their sustainable use. This global good will be used by district agricultural extension workers, and policy decision makers in developing countri ....Devising a methodology for the digital soil map of the world. Soil mapping is a key part of land-resource assessment for sustainable environmental management. The output will enable the use of soil data and information to give a clear understanding of the status of, and changes in, the nation's land, vegetation and water resources and implications for their sustainable use. This global good will be used by district agricultural extension workers, and policy decision makers in developing countries to assist in improved crop production and sustainable land management.

Metabolite pools and their implications for plant responses to global change. Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest. Flexibility in core processes of plant functi ....Metabolite pools and their implications for plant responses to global change. Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest. Flexibility in core processes of plant function represents a significant opportunity to develop such tools. With a focus on plant metabolites, this project will characterise how Australian trees alter the allocation of resources to cope with environmental changes and produce metabolite-based selective traits for stress tolerance in Australian trees.

The physiological ecology of forest succession: explaining shade tolerance variation in evergreen and deciduous trees. This work will strengthen both the theoretical framework and the local knowledge base for sustainable timber production from natural forests, and for habitat restoration programs (National Research Priority 1.5: Sustainable Use of Australia's Biodiversity). These same advances of global and local relevance will also enable better quality input into models predicting vegetation d ....The physiological ecology of forest succession: explaining shade tolerance variation in evergreen and deciduous trees. This work will strengthen both the theoretical framework and the local knowledge base for sustainable timber production from natural forests, and for habitat restoration programs (National Research Priority 1.5: Sustainable Use of Australia's Biodiversity). These same advances of global and local relevance will also enable better quality input into models predicting vegetation dynamics under climate change scenarios (Research Priority 1.7: Responding to climate change & variability). Furthermore, by clarifying relationships of shade tolerance with other stress-tolerance strategies, this work will help us understand the evolutionary potential of local floras to respond to global change.Read moreRead less
