Ecology of fine root endophytes in native and agricultural ecosystems. This project aims to investigate the abundance, diversity and function of fine root endophytes in Australian native and agricultural ecosystems in response to recent genetic data proving they are taxonomically distinct from the well-studied arbuscular mycorrhizal fungi. The project aims to complete a comprehensive field survey, novel molecular analyses and innovative glasshouse experiments. Outcomes should include globally si ....Ecology of fine root endophytes in native and agricultural ecosystems. This project aims to investigate the abundance, diversity and function of fine root endophytes in Australian native and agricultural ecosystems in response to recent genetic data proving they are taxonomically distinct from the well-studied arbuscular mycorrhizal fungi. The project aims to complete a comprehensive field survey, novel molecular analyses and innovative glasshouse experiments. Outcomes should include globally significant insights into fine root endophytes and their role in plant growth. The project will strengthen capacity to predict impacts of global environmental change on ecosystem functions driven by the soil rhizosphere.Read moreRead less
The biogeochemical cycles of Ni and Co, a functional approach to ecological restoration of lateritic soils. Nickel is an essential metal for many technologies, and a key component of Australia's resource industry. Nickel exports contribute in excess of Aus$2 billion per annum to the economy. To date, most of Australia's Ni production has come from sulphide ores but the current development of large lateritic Ni operations in Western Australia will result in most production coming from lateritic N ....The biogeochemical cycles of Ni and Co, a functional approach to ecological restoration of lateritic soils. Nickel is an essential metal for many technologies, and a key component of Australia's resource industry. Nickel exports contribute in excess of Aus$2 billion per annum to the economy. To date, most of Australia's Ni production has come from sulphide ores but the current development of large lateritic Ni operations in Western Australia will result in most production coming from lateritic Ni ore. Hence increasing the research effort on ecological restoration of these large opencast mines is essential to ensure an environmentally sustainable Australia. This project will set up strategies to maintain biodiversity using geochemical and biological technologies to minimise environmental risk.Read moreRead less
Understanding why aluminium and other trace metals are toxic to plants - the key to improving crop yield in degraded soils. Aluminium toxicity drastically reduces plant growth in acid soils, costing Australia approximately $1.5 billion per annum in lost productivity. This project will aim to identify the reasons behind the toxicities of aluminium and other metals and has the potential to increase yields in 50 per cent of Australia’s agricultural land which is acidic.
