Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will ....Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will resolve the roles of environmental drivers of soil respiration across forests; integrate mechanistic understanding of differing plant and microbial responses to temperature within a common modelling framework; and evaluate the implications of this knowledge in predictions of climatic impacts on terrestrial carbon cycling.Read moreRead less
Predicting and improving the productivity of plants in future climates. Earth's atmospheric carbon dioxide (CO2) sustains all terrestrial vegetation, yet the effects of increasing concentrations of this gas on plant productivity are difficult to predict. The project aims to undertake experiments on the leaf-level processes that underpin plant productivity in multiple global vegetation systems. This could enable the development of a new theoretical approach to predicting plant productivity in cha ....Predicting and improving the productivity of plants in future climates. Earth's atmospheric carbon dioxide (CO2) sustains all terrestrial vegetation, yet the effects of increasing concentrations of this gas on plant productivity are difficult to predict. The project aims to undertake experiments on the leaf-level processes that underpin plant productivity in multiple global vegetation systems. This could enable the development of a new theoretical approach to predicting plant productivity in changed environmental circumstances at all scales. The results of this project could provide new tools for understanding the vulnerabilities and sensitivities of natural and managed landscapes under environmental pressures associated with increasing CO2.Read moreRead less

Summary
Generalising a root-water uptake mechanism for successful land surface modelling. Understanding root functioning in Australian savanna ecosystems is critically important for successful resource management but such understanding is not represented in land surface models (LSMs). This project will incorporate root functioning into LSMs and improve our ability to manage water and carbon natural resources in a changing climate.
When fire and water mix: do carbon dioxide-related water savings drive woody plant thickening and fire dynamics in a grassy woodland? Australia's woodland landscapes have experienced widespread shrub expansion in the last century due to changes in fire, grazing and atmospheric carbon dioxide. This project will endevour to fill critical gaps in the nexus between carbon dioxide-induced effects on vegetation and fire disturbance to help explain this phenomenon and help manage Australian woodlands i ....When fire and water mix: do carbon dioxide-related water savings drive woody plant thickening and fire dynamics in a grassy woodland?

Optimising feeds to support ecosystem-based aquaculture. This project aims to assess the global and local consequences of changing feeds in aquaculture by developing a new interdisciplinary sustainability assessment framework. The project expects to generate new methods to understand and predict local farm-to-ecosystem changes and global environmental footprints under contrasting feed and climate scenarios by integrating field data with novel experiments, modelling techniques and global mapping ....Optimising feeds to support ecosystem-based aquaculture. This project aims to assess the global and local consequences of changing feeds in aquaculture by developing a new interdisciplinary sustainability assessment framework. The project expects to generate new methods to understand and predict local farm-to-ecosystem changes and global environmental footprints under contrasting feed and climate scenarios by integrating field data with novel experiments, modelling techniques and global mapping of terrestrial and marine feed raw materials and their impacts. Expected outcomes include new methods to assess ecological, social and economic trade-offs under different feeds to inform decision making in support of an ecosystem-based approach to aquaculture spanning global to local scales.Read moreRead less
Living on the edge: how do Australian plants cope with extreme temperature? Of all the climatic factors determining species distributions, temperature is arguably the most important. It is extremes – rather than averages – that drive species evolution. So it is concerning that although extreme temperature events are increasing in frequency and intensity little is known about the breadth of thermal tolerance of plants from extreme environments. This information is crucial to understand species di ....Living on the edge: how do Australian plants cope with extreme temperature? Of all the climatic factors determining species distributions, temperature is arguably the most important. It is extremes – rather than averages – that drive species evolution. So it is concerning that although extreme temperature events are increasing in frequency and intensity little is known about the breadth of thermal tolerance of plants from extreme environments. This information is crucial to understand species distribution and survival under future climate regimes. This project will ascertain the thermal breadth of Australian species growing in situ and under controlled environments. The project will contribute to development of effective conservation, restoration and rehabilitation plans for Australian native plant communities. Read moreRead less

Impacts of extreme hydro-meteorological conditions on ecosystem functioning and productivity patterns across Australia. As Earth’s climate continues to change, the frequency and intensity of warm droughts, extreme precipitation patterns, and heat waves will alter in potentially different ways, ecosystem functioning and productivity with major impacts on carbon and water balance, and food security. The extreme hydro-meteorological conditions that are presently afflicting Australia provide excepti ....Impacts of extreme hydro-meteorological conditions on ecosystem functioning and productivity patterns across Australia. As Earth’s climate continues to change, the frequency and intensity of warm droughts, extreme precipitation patterns, and heat waves will alter in potentially different ways, ecosystem functioning and productivity with major impacts on carbon and water balance, and food security. The extreme hydro-meteorological conditions that are presently afflicting Australia provide exceptional opportunities to study ecosystem-level functional responses using contemporary, in-situ and satellite observational datasets. This project aims to analyse cross-biome and site-level functional responses across contrasting hydroclimatic periods to better understand climate change impacts on ecosystem productivity, resilience, and potential collapse.Read moreRead less
