How plants survive droughts

Understanding which plant species can recover from drought, under what conditions and the processes involved, will help researchers predict plant mortality in response to global climate change. In response to drought, some species die because of embolism-induced hydraulic failure, while others recover, following rehydration. This research focuses on structures and processes that might allow some plants to recover from drought stress via embolism reversal.

Mapping transpiration in climate models

When researchers compared the results derived from FLUXNET data with the results synthesised from the literature, they found substantial differences.
As a result, they suggest a new benchmarking metric that could be used to test existing hypotheses embedded in climate models and have mapped a path forward involving using further detailed observations to improve the way coupling/decoupling processes currently represented in climate models.

Understanding water-use efficiency in plants

This study explored the key sources of uncertainty when scaling leaf-level understanding of water-use efficiency to ecosystem scales. The results provide key insights into interpreting (ecosystem-scale) eddy-covariance derived water-use efficiency in an ecophysiological context.
