Limits to the resilience of Australian forests and woodlands to drought. Water availability is a primary determinant of plant growth and the distribution of plant species and communities throughout the world. In Australia, climate change is predicted to result in increasing temperatures and shifting precipitation patterns, leading to more intense droughts in some areas.

Water availability is a primary determinant of plant growth and the distribution of plant species and communities throughout the world. In Australia, climate change is predicted to result in increasing temperatures and shifting precipitation patterns, leading to more intense droughts in some areas. This project will examine the resilience of Australian forests and woodlands to drought under both current and future climate scenarios. The results of this work will feed into the new generation of dynamic global vegetation models, allowing for robust prediction of changes in the structure and productivity of Australian vegetation communities in the face of rapid climate change.Read moreRead less
The metabolic footprint of plants. Plant roots "leak" 5-10% of the C fixed in photosynthesis. Surprisingly, we have a limited understanding of which compounds leak from roots.This project will identify the compounds leaking from roots and explore their function in tolerance of biotic and abiotic stress and implications for soil respiration.
Drought and death: past, present and future survival limits in the Australian vegetation landscape. Science cannot predict the point at which water stress becomes lethal for plants. This research into plant water transport aims to find a new way to understand whether plant species will die or adapt to a future drier climate.
