Switching partners: a driving force for tree productivity in a changing environment? Eucalypts take part in a mutually beneficial association with diverse communities of mycorrhizal fungi to satisfy nutrient demands. The fungi that eucalypts interact with change as they grow but the reasons for this shift are not known. To improve forestry management strategies, the project will determine why and how this shift occurs.
The endangered swift parrot as a model for managing small migratory birds.

Summary
Understanding plant:fungal communication to increase plant productivity. Relationships between mutualistic fungi and plants are exploited as they foster plant productivity and vigour. One significant problem facing the agro-forestry and agricultural industries is that the ability of beneficial fungi to colonise plant hosts is highly dependent on the genetic background of the host. Ultimately, this means that if fungal inoculants are not matched with the appropriate plant host, maximal benefits f ....Understanding plant:fungal communication to increase plant productivity. Relationships between mutualistic fungi and plants are exploited as they foster plant productivity and vigour. One significant problem facing the agro-forestry and agricultural industries is that the ability of beneficial fungi to colonise plant hosts is highly dependent on the genetic background of the host. Ultimately, this means that if fungal inoculants are not matched with the appropriate plant host, maximal benefits from these relationships are not achieved. This project aims to identify the first genetic markers to be used for matching plants with appropriate fungal isolates, thereby guaranteeing optimal plant performance. This will add a critical component to the global effort of increasing the productivity of our natural resources.Read moreRead less
Factors controlling ectomycorrhizal contributions to plant N nutrition. This project aims to define the mechanistic link between nitrogen metabolism in symbiotic ectomycorrhizal fungi and its effect on the quantity of nitrogen shared with a plant host. Using a genetically diverse population of a key Australian fungal species, the project expects to uncover genetic features related to nitrogen metabolism that correlate to improved support of plant nutrition. Expected outcomes include better under ....Factors controlling ectomycorrhizal contributions to plant N nutrition. This project aims to define the mechanistic link between nitrogen metabolism in symbiotic ectomycorrhizal fungi and its effect on the quantity of nitrogen shared with a plant host. Using a genetically diverse population of a key Australian fungal species, the project expects to uncover genetic features related to nitrogen metabolism that correlate to improved support of plant nutrition. Expected outcomes include better understanding of plant-microbe interactions, groundwork for tools to better model the role of fungi in soil nutrient cycling and guidelines for plant:fungal pairings in reforestation practices. Overall, these should provide significant benefit to the global effort in understanding the role of soil microbes in plant nutrition.Read moreRead less
Characterising controls of carbon flow from trees into mycorrhizal fungi. This project aims to improve our understanding of below-ground carbon sequestration. A significant portion of plant photosynthate is shuttled to root-associated mutualistic ectomycorrhizal fungi in forest ecosystems. Therefore, fungal partners of forest trees are valuable carbon sinks. One problem impeding below-ground carbon accounting in forest soils is a lack of understanding concerning the genetic control of how photos ....Characterising controls of carbon flow from trees into mycorrhizal fungi. This project aims to improve our understanding of below-ground carbon sequestration. A significant portion of plant photosynthate is shuttled to root-associated mutualistic ectomycorrhizal fungi in forest ecosystems. Therefore, fungal partners of forest trees are valuable carbon sinks. One problem impeding below-ground carbon accounting in forest soils is a lack of understanding concerning the genetic control of how photosynthetically fixed sugars are passed to root-associated microbes. This project aims to identify and characterise the sugar transporters that shuttle carbon in ectomycorrhizal plant–fungal interactions and investigate how these are affected by elevated carbon dioxide. It may also identify isolates of mutualistic fungi that could be paired with eucalypt hosts to maximise carbon sequestration and forest productivity.Read moreRead less
Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers throu ....Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers through a series of experiments. The expected outcome of this project is a clear understanding of the role of traits in wood decomposer communities, especially their influence on priority effects, competitive hierarchies, and the resultant wood decay rate.Read moreRead less
Are Secreted Proteins determinants of host range in ectomycorrhizal fungi? This project aims to understand the role of small secreted proteins in governing symbiotic fungal-host compatibility and determine the impact of environmental change on the role of these proteins. Using innovative approaches, this project expects to achieve these goals using comparative genomics, transcriptomic analyses and functional characterisation of these proteins within a keystone Australian ectomycorrhizal fungus. ....Are Secreted Proteins determinants of host range in ectomycorrhizal fungi?

Using innovative approaches, this project expects to achieve these goals using comparative genomics, transcriptomic analyses and functional characterisation of these proteins within a keystone Australian ectomycorrhizal fungus. It is anticipated that outcomes of this project will add a critical component to the global effort in understanding the role of soil microbes in supporting the health of plants experiencing a variety of climactic conditions. This could provide significant benefits to informing management practices of forest ecosystems.Read moreRead less
Surviving the inferno: how threatened macropods survive catastrophic fire. This project aims to determine the impact of the catastrophic black summer fires of 2019/20 on threatened wallabies, including the parma wallaby (that had 70% of its entire distribution burnt) and the red-legged pademelon. Following these fires, wildlife across Australia has been decimated. This project expects to generate new knowledge by comparing burnt and unburnt areas before and after the fires to determine their imp ....Surviving the inferno: how threatened macropods survive catastrophic fire. This project aims to determine the impact of the catastrophic black summer fires of 2019/20 on threatened wallabies, including the parma wallaby (that had 70% of its entire distribution burnt) and the red-legged pademelon. Following these fires, wildlife across Australia has been decimated. This project expects to generate new knowledge by comparing burnt and unburnt areas before and after the fires to determine their impact on threatened wallaby conservation ecology. The expected outcomes of this project include improved understanding of the impact of fires on Australia's iconic wildlife. This should significantly improve our ability to reduce the risk on these species in future megafires. Read moreRead less

Novel experimental and longitudinal analyses to promote woodland biota. This project aims to close important scientific and practical application gaps around the most effective ways to restore and manage vegetation on farms. Although restoration programs to increase native vegetation cover are essential for integrating agricultural production with biodiversity conservation, critical scientific questions remain about how biota responds to temporal increases in vegetation cover. This project will combine novel spatiotemporal analyses of long-term datasets and a blocked and replicated experiment comparing planting strategies that connect woodland patches vs augmentation strategies that increase individual patch size. Anticipated outcomes are better designed and implemented restorations to maximise benefits for biota.Read moreRead less
