Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less

Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less
Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in r ....Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in reducing uptake. Results will be relevant to most crop plants, because of the widespread occurrence of the symbioses. The project will enhance collaboration with China where arsenic toxicity is prevalent, provide education and training in an internationally recognised laboratory and enhance Australia's reputation for tackling soil contamination.Read moreRead less
The contribution of beneficial arbuscular mycorrhizal (AM) fungi to sustainable tomato production in Australia. Formation of beneficial arbuscular mycorrhiza (AM) by processing tomatoes has been used as an indicator of 'healthy soil' in an environmental monitoring audit of the industry in southern Australia, but field occurrence of the AM fungi and their potential contribution to tomato nutrition and productivity are not well understood. We will determine the responsiveness of widely-grown tomat ....The contribution of beneficial arbuscular mycorrhizal (AM) fungi to sustainable tomato production in Australia. Formation of beneficial arbuscular mycorrhiza (AM) by processing tomatoes has been used as an indicator of 'healthy soil' in an environmental monitoring audit of the industry in southern Australia, but field occurrence of the AM fungi and their potential contribution to tomato nutrition and productivity are not well understood. We will determine the responsiveness of widely-grown tomato varieties to AM inoculation and relate colonisation in the field to farming practices. The results will determine the potential benefits of AM fungi to tomato crops, in the context of development of environmentally and economically sustainable practices both in Australia and overseas.

This project aims to improve the practice of seed banking for the conservation of the Australian flora. Recent evidence points to diverse and complex storage behaviour for wild seeds and to seeds of many species being shorter-lived than anticipated. Predicting seed storage behaviour and viability decline is central to effective seedbanking. This project expects to develop new high throughput technologies and data interrogation techniques for predicting seed lifespan in storage, and alternative storage protocols for problematic seeds. Results will allow seed bank managers to more efficiently triage and curate their seed collections and will benefit seed banks globally.Read moreRead less

Each year invasive plants cost Australia billions of dollars through costs associated with their control and through lost agricultural production and degradation of native ecosystems. Two particularly damaging plants are gorse and broom. The problems gorse causes are so serious that it has been recognized as a Weed of National Significance (Federal Department of Environment and Heritage). Biological control efforts have seldom use native agents, and even less often, parasitic plants. This project will help to develop strategies for the control of two noxious species using a native parsitic plant.Read moreRead less
