Forest ecosystem responses to climate change
Our research mainly deals with tree physiological responses to climate (change). It enabels us to conclude about species-specific thresholds in terms of climate variables (drought stress, frost stress, extreme events etc.) and its consequences for forest ecosystems in the future.
