The goal of this project is to improve our understanding of the impacts of two key drivers of global climate change – rising temperatures and increasing concentrations of atmospheric carbon dioxide ([CO₂]) – on leaf respiration (R_d). While much is known about the impacts of rising temperatures and [CO₂] on photosynthesis, the impact of elevated temperature and [CO₂] on day-to-day variability in leaf R_d is poorly understood. To address this knowledge gap, this project will discover how warming and elevated [CO₂] influence variations in R_d in Australian broad-leaved, evergreen temperate and tropical trees. The project will elucidate mechanisms linking R_d to photosynthesis and carbohydrate mobilisation - key processes that drive daily variations in R_d. The project will deliver a process-based framework through which dynamic changes in R_d can be predicted by climate models now and in the future.

Student intake: One fully funded PhD position is available (PhD scholarship is available through an associated DECRA project awarded to Dr. Eric Dusenge provided the student has an H1 grade)
