This project aims to establish the scientific basis for silvicultural treatments of eucalypt plantations for clear wood production. While eucalypt plantations in north-eastern NSW have dramatically increased in recent times, the knowledge base for the production clear, branch-free wood from the tree species used does not exist. A physiological, mechanistic understanding of crown and canopy dynamics as well as branch shedding will form the scientific foundation for stand manipulations such as pruning and thinning to enhance wood quality. Project outcomes will provide the basis for a stand management simulation model for the most important eucalypt species.Read moreRead less
Quantifying tree and soil respiration and their responses to global change. The Australian Greenhouse Office, as well as independent analysis, recognizes that belowground processes must be better quantified if Australia's contributions to atmospheric concentrations of greenhouse gases (GG) are to be firmly based. A major issue is the lack of dedicated research focused on soil and plant root emissions of GG and, in particular, a lack of testing of methodologies suited to Australian soils and con ....Quantifying tree and soil respiration and their responses to global change. The Australian Greenhouse Office, as well as independent analysis, recognizes that belowground processes must be better quantified if Australia's contributions to atmospheric concentrations of greenhouse gases (GG) are to be firmly based. A major issue is the lack of dedicated research focused on soil and plant root emissions of GG and, in particular, a lack of testing of methodologies suited to Australian soils and conditions. This project will address these concerns. We will also be addressing the clear need for further training of PhD qualified researchers in the field of climate change. Read moreRead less

The capacity of forests to protect regional climate under global warming. The project plans to develop a new understanding of the capacity of forests to increase moisture recycling, which enhances cloud and precipitation processes and exerts a cooling influence on the land surface. Deforestation and climate change are major global challenges. The role of forests in the carbon cycle is well recognised. Less attention is given to their role in the energy and water cycles, and their capacity to reg ....The capacity of forests to protect regional climate under global warming. The project plans to develop a new understanding of the capacity of forests to increase moisture recycling, which enhances cloud and precipitation processes and exerts a cooling influence on the land surface. Deforestation and climate change are major global challenges. The role of forests in the carbon cycle is well recognised. Less attention is given to their role in the energy and water cycles, and their capacity to regulate regional climate. The project plans to apply an innovative land use-climate scenario modelling to quantify the impacts of deforestation and afforestation on the climate of northern Australia and south-east Asia under global warming. It also plans to evaluate the capacity of restoring forests to offset regional climate change, to inform regional land use planning and climate mitigation and adaptation.Read moreRead less

Temperature response and thermal acclimation of mesophyll conductance. Photosynthetic rate and efficiency depend on diffusion of carbon dioxide from the atmosphere into leaf mesophyll cells. Carbon dioxide diffusion is affected by temperature, but we lack knowledge of how this varies between plant species. Stable isotope methodology will be used to characterise the temperature response of this carbon dioxide diffusion step. Plants from contrasting climates will be grown in different temperature ....Temperature response and thermal acclimation of mesophyll conductance. Photosynthetic rate and efficiency depend on diffusion of carbon dioxide from the atmosphere into leaf mesophyll cells. Carbon dioxide diffusion is affected by temperature, but we lack knowledge of how this varies between plant species. Stable isotope methodology will be used to characterise the temperature response of this carbon dioxide diffusion step. Plants from contrasting climates will be grown in different temperature regimes to reveal the extent of variation in adaptation and acclimation to temperature. This will provide new insights towards modifying photosynthesis to increase crop yield and it will also improve forecasting of global atmospheric carbon dioxide fluxes derived from the analysis of atmospheric isotope data.Read moreRead less
