Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new k ....Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new knowledge on how fire influences soil-to-atmosphere C fluxes in a warmer climate using a multi-disciplinary approach. Expected outcomes include an enhanced capacity to predict the terrestrial ecosystem-to-atmosphere C fluxes and their feedbacks to climate under increasing frequency of fire using Earth-system models.

Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the fir ....Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the first time, couple advanced oxygen sensing, metabolic physiology, coral reproductive and stress biology to transform our understanding of oxygen thresholds that are diagnostic of reduced coral competitive fitness across life stages (adults, juveniles, larvae), needed to improve coral reef ecosystem management.Read moreRead less

Summary
Plant community responses to fire regime: the role of plant–soil feedbacks. We need to know how different prescribed burning regimes set the stage for long-term changes in plant community composition, diversity, and flammability. This project aims to reveal how plant community dynamics under different fire scenarios can be predicted based on contemporary interactions between plants and soil micro-organisms. This innovative approach to fire ecology integrates soil biology and plant ecophysiology ....Plant community responses to fire regime: the role of plant–soil feedbacks. We need to know how different prescribed burning regimes set the stage for long-term changes in plant community composition, diversity, and flammability. This project aims to reveal how plant community dynamics under different fire scenarios can be predicted based on contemporary interactions between plants and soil micro-organisms. This innovative approach to fire ecology integrates soil biology and plant ecophysiology with sophisticated experiments and novel modelling techniques. Expected outcomes include a much-needed mechanistic framework for early detection of major ecological changes under novel fire regimes, with direct benefits for land managers and the long-term conservation of Australia’s iconic vegetation.Read moreRead less
Developing feasible in situ control of mange disease in wombats. Our goal is the development of feasible in situ control of sarcoptic mange in wombat populations. Globally important, the Sarcoptes scabiei mite infects >100 mammal species and is among the 50 most common human diseases, causing health, welfare and population impacts. This infection is treatable, and we will test a new treatment (fluralaner), develop new models to guide management, and conduct replicated field trials.

Globally important, the Sarcoptes scabiei mite infects >100 mammal species and is among the 50 most common human diseases, causing health, welfare and population impacts. This infection is treatable, and we will test a new treatment (fluralaner), develop new models to guide management, and conduct replicated field trials. This will enable science-based guidelines, advancing disease control, local eradication, and regulatory approval for wombats. Our research framework is adaptable to other mange-impacted species, and advance methods and theory for control of treatable disease in wildlife.Read moreRead less
New metrics to measure and track fauna community condition in Australia. This project aims to improve how biodiversity is measured by developing a system to describe the condition of animal communities, analogous to those used for plant communities. It develops and tests the system for Australia’s birds, then extends the approach to other animal groups. The project expects to develop a data-driven typology of bird communities, accompanying community condition metrics that are scalable from site ....New metrics to measure and track fauna community condition in Australia. This project aims to improve how biodiversity is measured by developing a system to describe the condition of animal communities, analogous to those used for plant communities. It develops and tests the system for Australia’s birds, then extends the approach to other animal groups. The project expects to develop a data-driven typology of bird communities, accompanying community condition metrics that are scalable from site to national levels, and guidance for using these metrics in practice. These metrics will enable holistic and relevant measures of the biodiversity value of sites, improve evaluation of restoration actions, reveal trends in community condition, and inform monitoring and evaluation tools for emerging biodiversity markets.Read moreRead less

This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling growth and survival. The expected outcome is to provide practical advice to restoration practitioners about the importance of matching the provenance of seed source to planting sites, and opportunities for selecting provenances pre-adapted to predicted future climatic conditions at planting sites.Read moreRead less
