Green or crispy: Which plants use transpiration to survive heatwaves? Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels.

Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types could be used to better forecast the potential effects of climate change on forest ecosystems. This project also expects to identify heat-tolerant tree species and their relevant physiological traits, which can improve the success of urban tree plantings to help create cooler, greener cities throughout Australia.Read moreRead less
Ecosystem response to climate and anthropogenic disturbances: implications for greenhouse gas emissions and nutrient cycling. Humanity is challenged with climate change, greenhouse gas emissions, declining fertiliser reserves and a need to feed the world's growing population. This project will result in greater understanding of how ecosystems can respond to these challenges and provide a framework to help Australia manage its agricultural and natural reserves.
Applications-oriented elucidation of germination triggers for Emu Bush seed. The project aims to determine the environmental and genetic mechanisms that currently limit seed germination in Emu Bush (Eremophila) species. The anticipated project outcomes aim to develop new technologies for efficient and mass production of Emu Bush seedlings. The outcomes will improve land restoration by increasing plant diversity and reducing establishment costs, and will also provide the nursery industry with nov ....Applications-oriented elucidation of germination triggers for Emu Bush seed. The project aims to determine the environmental and genetic mechanisms that currently limit seed germination in Emu Bush (Eremophila) species. The anticipated project outcomes aim to develop new technologies for efficient and mass production of Emu Bush seedlings. The outcomes will improve land restoration by increasing plant diversity and reducing establishment costs, and will also provide the nursery industry with novel products for home gardens. The intended project benefits are to increase the diversity of Australian native plants used for restoration and ornamental purposes and to promote the conservation of species in this plant family and its genetic diversity.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

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.

This project aims to provide an evidence base for coral reef management to be targeted towards regions at greatest risk, and those that have the greatest capacity for acclimation under near-future climate change. This project will undertake an innovative trans-disciplinary analysis of coral thermal tolerance and the implications for targeted coral reef conservation to mitigate the impacts of climate change across the Great Barrier Reef ....Developing a mechanistic basis for coral reef conservation. This project aims to provide an evidence base for coral reef management to be targeted towards regions at greatest risk, and those that have the greatest capacity for acclimation under near-future climate change. This project will undertake an innovative trans-disciplinary analysis of coral thermal tolerance and the implications for targeted coral reef conservation to mitigate the impacts of climate change across the Great Barrier Reef (GBR). The project will provide significant benefits, by assisting in the maintenance of the goods and services (tourism, fisheries, shoreline protection) provided to Australia by the GBR.Read moreRead less
Towards operational monitoring of key climate parameters from synthetic aperture radar. Agricultural productivity is a major contributor to the Australian economy, but is experiencing significant stress in response to climate change. Moreover, soil moisture controls vegetation dynamics that contribute to carbon storage, atmospheric processes leading to severe weather, and runoff generation processes leading to floods and runoff yield from urban water storage catchments. Consequently, high reso ....Towards operational monitoring of key climate parameters from synthetic aperture radar. Agricultural productivity is a major contributor to the Australian economy, but is experiencing significant stress in response to climate change. Moreover, soil moisture controls vegetation dynamics that contribute to carbon storage, atmospheric processes leading to severe weather, and runoff generation processes leading to floods and runoff yield from urban water storage catchments. Consequently, high resolution time-series information on soil moisture and vegetation status from space represents a powerful tool for understanding climate change impacts on Australia. It is therefore imperative that products be developed specifically for the Australian environment to take full advantage of radar data from satellites.Read moreRead less
Diagnosing coral health tipping points under accelerating coastal hypoxia. This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia.

This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia. This project will couple advanced oxygen sensing, metabolic physiology and functional genomics techniques to transform our understanding of how corals and their associated microbial communities respond to reduced oxygen conditions, which is essential to improve coral reef ecosystem management.Read moreRead less
