Understanding fungal diversity and functioning in forest soils using molecular and stable isotope approaches. The project aims to investigate fungal community structure and functioning in forest soils using novel molecular, stable isotope and physiological approaches. This will provide new insights into the linkage between diversity and functioning in forest soil fungal communities and the importance of these organisms in ecosystem processes. In addition, this pioneering research will facilitate ....Understanding fungal diversity and functioning in forest soils using molecular and stable isotope approaches. The project aims to investigate fungal community structure and functioning in forest soils using novel molecular, stable isotope and physiological approaches. This will provide new insights into the linkage between diversity and functioning in forest soil fungal communities and the importance of these organisms in ecosystem processes. In addition, this pioneering research will facilitate development and refinement of methodologies that will pave the way for future investigations of fungal ecology. The on-going collaboration will produce high quality joint publications and provide significant opportunities for early career researchers to gain international experience in a dynamic research environment.Read moreRead less
Future climate change: consequences for decomposition and pathways of carbon flow through rhizosphere fungal communities. The proposed collaboration will provide novel insights into likely consequences of global climate change on decomposition and pathways of carbon flow through forest soils. This will refine predictive models of future climate change and its impacts on the sustainability of Australia's forests. It will also enhance the protection of our valued habitats and their important soil ....Future climate change: consequences for decomposition and pathways of carbon flow through rhizosphere fungal communities. The proposed collaboration will provide novel insights into likely consequences of global climate change on decomposition and pathways of carbon flow through forest soils. This will refine predictive models of future climate change and its impacts on the sustainability of Australia's forests. It will also enhance the protection of our valued habitats and their important soil biodiversity. The knowledge gained will help land managers to adapt current practices to meet the demands of future climate change. This will maximize the opportunities for sequestering carbon in Australia's forests and so contribute to meeting Australia's global responsibility for mitigation of climate change.Read moreRead less
Understanding plant uptake of organic and inorganic nitrogen for optimal fertiliser application in forestry. Nitrogen (N) in soils occurs in both organic and inorganic forms. Plants can take up inorganic N - nitrate and ammonium - but, on average, these account for only 5% of the soluble N in soils. Recent evidence suggests that plants may be able to tap into some of the 95% of N that occurs in organic forms. We will investigate the importance of organic N uptake for two plantation Eucalyptus sp ....Understanding plant uptake of organic and inorganic nitrogen for optimal fertiliser application in forestry. Nitrogen (N) in soils occurs in both organic and inorganic forms. Plants can take up inorganic N - nitrate and ammonium - but, on average, these account for only 5% of the soluble N in soils. Recent evidence suggests that plants may be able to tap into some of the 95% of N that occurs in organic forms. We will investigate the importance of organic N uptake for two plantation Eucalyptus species by tracing the uptake of different N forms by bacteria, fungi and eucalypts. This information will redefine what is meant by 'available N' and will guide the development of a new test for soil N status.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
