Lags and legacies: antecedent effects on grassland biomass response to carbon dioxide. This project aims to assess how past conditions influence grassland responses to the rising atmospheric concentration of carbon dioxide. High CO2 concentrations should stimulate productivity but in grasslands this is rarely realised because other, mostly unknown, factors constrain the response. By synthesising data from past experiments, this project aims to determine exactly why grasslands fail to realise the ....Lags and legacies: antecedent effects on grassland biomass response to carbon dioxide. This project aims to assess how past conditions influence grassland responses to the rising atmospheric concentration of carbon dioxide. High CO2 concentrations should stimulate productivity but in grasslands this is rarely realised because other, mostly unknown, factors constrain the response. By synthesising data from past experiments, this project aims to determine exactly why grasslands fail to realise the full productivity benefits of increased CO2 and when this will happen. This should improve predictions of carbon exchange and indicating the best direction for climate change adaptation measures.Read moreRead less
Carbon in - carbon out: can carbon inputs keep up with losses in peatland? This project aims to quantify the current and predict the future carbon balance of a high altitude, carbon-dense ecosystem, namely sub-alpine grassy peatland, by measuring how environmental variables including experimental warming control the fluxes of carbon and water into and out of the system. In this way, this project will produce new knowledge on the susceptibility of high-altitude peaty soils to climate change. Expe ....Carbon in - carbon out: can carbon inputs keep up with losses in peatland? This project aims to quantify the current and predict the future carbon balance of a high altitude, carbon-dense ecosystem, namely sub-alpine grassy peatland, by measuring how environmental variables including experimental warming control the fluxes of carbon and water into and out of the system. In this way, this project will produce new knowledge on the susceptibility of high-altitude peaty soils to climate change. Expected outcomes include an enhanced ability to predict future carbon accumulation rates and the resilience of the vital water-storage and filtration services provided by these systems. This project will enhance outputs from new infrastructure and assist planning for future flood and drought management across SE Australia.Read moreRead less

A transdisciplinary assessment. Geoengineering the Southern Ocean? A transdisciplinary assessment. The project aims to comprehensively evaluate the feasibility of offsetting climate change by using geoengineering to boost carbon dioxide removal by Southern Ocean microbes. With existing polar datasets as a platform, the project would combine experiments and modelling to quantify carbon dioxide removal and critically assess the economic feasibility and side effects of geoengineering. Anticipated outcomes include a framework for governance of future research and informed national/international policy on using geoengineering to mitigate climate change.Read moreRead less
Meta-modelling of ecological, evolutionary and climatic systems dynamics. This project aims to improve forecasts of the response of biodiversity to future climate change and so improve on-ground conservation management. Using dynamic systems modelling, tested against field data from a wide variety of case studies, the project models will integrate a variety of biological and geophysical inputs to produce more realistic forecasts of change.
Systems modelling for synergistic ecological-climate dynamics. The project aims to improve forecasts of the response of biodiversity to future climate change and so improve on-ground conservation management. A systems modelling framework will be developed and tested against real-world data to integrate a wide variety of biological and geophysical inputs and so produce more realistic predictions.
Seaweed forests of the future: responses to ocean acidification and warming. The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics. Seaweeds create habitats and food for shellfish and fish, and play a crucial role in long term ‘blue carbon’ storage. They are predicted to benefit from future carbon dioxide enrichment, but to test this forecast r ....Seaweed forests of the future: responses to ocean acidification and warming. The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics. Seaweeds create habitats and food for shellfish and fish, and play a crucial role in long term ‘blue carbon’ storage. They are predicted to benefit from future carbon dioxide enrichment, but to test this forecast requires a detailed understanding of the mechanisms used by seaweeds to acquire dissolved inorganic carbon. The expected outcome is robust predictions of how the primary productivity of coastal waters will respond to future high carbon dioxide conditions, enabling human adaptation to environmental change.

Disaggregating and modelling the impacts of land-use change on biodiversity. This project aims to systematically analyse contemporary and historical data on agriculture, energy use and urbanisation, to identify the consumption and technology pathways that can most effectively mitigate the future extent and impact of land-use change. This synthesis is expected to develop new forecasting and optimisation tools using an innovative hierarchical meta-modelling approach. A key outcome would be to resolve inherent global and national trade-offs between ongoing human development and the competing need to conserve habitats, ecosystems, and species.Read moreRead less
Mechanisms of acclimation of coralline algae to ocean acidification. This project aims to investigate the biological and ecological mechanisms by which reef-building coralline algae may have survived past ocean acidification and warming events and may acclimate to future changes. Coralline algae play critical roles in coral reef ecology but are sensitive to human-induced ocean acidification. However, the abundant geological record coincident with past acidification events is inconsistent with th ....Mechanisms of acclimation of coralline algae to ocean acidification. This project aims to investigate the biological and ecological mechanisms by which reef-building coralline algae may have survived past ocean acidification and warming events and may acclimate to future changes. Coralline algae play critical roles in coral reef ecology but are sensitive to human-induced ocean acidification. However, the abundant geological record coincident with past acidification events is inconsistent with their sensitivity to high carbon dioxide. Acclimation and adaptation is therefore possible but in ways we do not yet understand. The project expects to provide insights to the ability of key marine organisms to acclimate to rapid environmental change and provide information critical for the conservation of valuable marine systems.Read moreRead less
