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

Animal cultures and anthropogenic change. This project aims to investigate the impacts of anthropogenic change on the elaborate song cultures of declining Australian songbirds. Culture is fundamental to the biology of social animals, and has profound implications for biodiversity conservation; however, the drivers of animal cultural change are unclear. This project will analyse how lyrebird song cultures respond to anthropogenic environmental change, including Australia’s 2019-20 megafires. Furt ....Animal cultures and anthropogenic change. This project aims to investigate the impacts of anthropogenic change on the elaborate song cultures of declining Australian songbirds. Culture is fundamental to the biology of social animals, and has profound implications for biodiversity conservation; however, the drivers of animal cultural change are unclear. This project will analyse how lyrebird song cultures respond to anthropogenic environmental change, including Australia’s 2019-20 megafires. Furthermore, it will assess the mechanisms linking environmental and cultural change, and examine the utility of vocal cultures as bioindicators of ecological health. This project will advance fundamental research in animal culture and enhance the conservation of cultural diversity in the wild.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
Hotspots of endemism for invertebrate conservation in south-east Australia. The project aims to identify and predict hotspots of species endemism to guide conservation and restoration efforts. This work is significant in the current extinction crisis because endemic species (those unique to a region) are at higher risk of extinction due to human causes. The project will model the relationship of narrow range endemic species with contemporary and past environments, estimate the historical loss of ....Hotspots of endemism for invertebrate conservation in south-east Australia. The project aims to identify and predict hotspots of species endemism to guide conservation and restoration efforts. This work is significant in the current extinction crisis because endemic species (those unique to a region) are at higher risk of extinction due to human causes. The project will model the relationship of narrow range endemic species with contemporary and past environments, estimate the historical loss of species through land-clearing and fire, and predict future responses to climate change, to inform conservation planning. Lastly, it will test the efficacy of habitat transplants in restoring local invertebrate assemblages. Benefits include better informed conservation planning and new restoration approaches.Read moreRead less
A network perspective for ecosystem responses to plant invasion. Invasive species are key drivers of global change, yet, our understanding of their negative impacts on ecosystems is limited within many contexts. This project will provide the first large-scale test for interactions between plants and microbes, via network analyses, as yardsticks for invasive species impacts on ecosystems. Using innovative approaches that link interactions network properties with ecosystem functioning, the fundame ....A network perspective for ecosystem responses to plant invasion. Invasive species are key drivers of global change, yet, our understanding of their negative impacts on ecosystems is limited within many contexts. This project will provide the first large-scale test for interactions between plants and microbes, via network analyses, as yardsticks for invasive species impacts on ecosystems. Using innovative approaches that link interactions network properties with ecosystem functioning, the fundamental data generated in this study will answer unsolved theoretical questions, providing evidence for the use of networks to predict and mitigate invader impacts. These benefits are not only crucial for biodiversity managers but also for those responsible for sustainable crop development under future climates.Read moreRead less
What determines plant sensitivity to heat?: Individual to lifetime impacts. Temperature is a major determinant of the distribution of species and yet the capacity to predict the thermal sensitivity of plants is extremely limited. How vulnerability varies as a plant grows from seed to adult and produces more seed is a key question. Whether chronic warming exacerbates or ameliorates effects of extreme events, e.g. triggering the plant to enlist defensive strategies, is also an open question. This ....What determines plant sensitivity to heat?: Individual to lifetime impacts. Temperature is a major determinant of the distribution of species and yet the capacity to predict the thermal sensitivity of plants is extremely limited. How vulnerability varies as a plant grows from seed to adult and produces more seed is a key question. Whether chronic warming exacerbates or ameliorates effects of extreme events, e.g. triggering the plant to enlist defensive strategies, is also an open question. This project will advance fundamental understanding of how thermal tolerance varies across species and over the plant life cycle and how it scales demographically to lifetime vulnerability. The work will yield a significant advance in our capacity to predict impacts of extreme heat events on plant performance and distribution.
