Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interac ....Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interactions, whilst models do not represent the functional characteristics and adaptions of eucalypts. This project will develop a strong evidence- and process-based understanding to quantify the functional behaviour of drought-adapted Eucalyptus species and leverage this insight to make future model projections.Read moreRead less
Variability in El Niño frequency and intensity over the past 4000 years. Fossil corals contain a rich archive of past climate variability for tropical oceans which can extend the limited instrumental data and increase our understanding of climate sensitivity. El Niño variations in the Pacific have far-reaching impacts on Australian climate, and this project will reconstruct variations in the past in order to better forecast climate sensitivity in the future. It focuses on Christmas Island whic ....Variability in El Niño frequency and intensity over the past 4000 years. Fossil corals contain a rich archive of past climate variability for tropical oceans which can extend the limited instrumental data and increase our understanding of climate sensitivity. El Niño variations in the Pacific have far-reaching impacts on Australian climate, and this project will reconstruct variations in the past in order to better forecast climate sensitivity in the future. It focuses on Christmas Island which is the optimal site to capture El Niño variability at several different time scales, and will lead to a better understanding of atmospheric and oceanic factors that have caused climate variability.Read moreRead less
Prioritising habitat restoration for biodiversity and ecosystem service outcomes.

This research will prioritise investments in habitat restoration in order to cost-effectively achieve biodiversity conservation and ecosystem service protection goals.
Brown is the new green: grassland responses to drought and heat. This project aims to improve accuracy and precision in predicting the impact of water availability and heat stress on grassland function. Grassland ecosystems are important reservoirs of global biodiversity and carbon storage. Grasslands are highly sensitive to drought and heat stress, but studies recently showed that current grassland models cannot predict these responses because they do not adequately represent the key processes ....Brown is the new green: grassland responses to drought and heat. This project aims to improve accuracy and precision in predicting the impact of water availability and heat stress on grassland function. Grassland ecosystems are important reservoirs of global biodiversity and carbon storage. Grasslands are highly sensitive to drought and heat stress, but studies recently showed that current grassland models cannot predict these responses because they do not adequately represent the key processes of physiological drought tolerance, leaf browning, and species traits. This project will collect targeted data sets in order to develop and test model representations of these key processes. This will provide significant benefits, such as greatly increasing capacity to predict the impact of drought and heat stress on grasslands, at scales ranging from field to globe.Read moreRead less
450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to a ....450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to assess its vulnerability to global climate change in relation to other nations, thereby informing national planning of landscape resource use, including primary industry, water infrastructure and carbon trading.Read moreRead less
Metabolite pools and their implications for plant responses to global change. Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest. Flexibility in core processes of plant functi ....Metabolite pools and their implications for plant responses to global change. Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest. Flexibility in core processes of plant function represents a significant opportunity to develop such tools. With a focus on plant metabolites, this project will characterise how Australian trees alter the allocation of resources to cope with environmental changes and produce metabolite-based selective traits for stress tolerance in Australian trees.

Past and future effects of climate change on the carbon-water balance of plants. Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-clim ....Past and future effects of climate change on the carbon-water balance of plants. Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-climate feedbacks. It will determine the combined effects of elevated atmospheric CO2 and drought on the productivity of natural and agricultural landscapes, and provide the biophysical framework for developing the next generation of high-yielding, drought tolerant crop varieties for the rapidly approaching greenhouse world.Read moreRead less
Portfolio projection of biodiversity responses under climate change. Organisms need to adapt and/or migrate to avoid critical population loss under climate change. Despite the importance of both processes in biodiversity dynamics, most biodiversity predictions focus on the patterns of migration under climate change. The type and amount of adaptation required to escape climate-driven extinction in the future remain largely unknown. This project aims to quantify the type and extent of adaptation a ....Portfolio projection of biodiversity responses under climate change. Organisms need to adapt and/or migrate to avoid critical population loss under climate change. Despite the importance of both processes in biodiversity dynamics, most biodiversity predictions focus on the patterns of migration under climate change. The type and amount of adaptation required to escape climate-driven extinction in the future remain largely unknown. This project aims to quantify the type and extent of adaptation and migration required for ecologically and economically important marine species to avoid critical population loss under climate change. By quantifying adaptive and migration responses as vulnerability metrics, the project outcomes will provide resource managers novel tools to formulate flexible management strategies.Read moreRead less
