The effects of short‐term extreme events on tree functioning and physiology are still rather
elusive. European beech is one of the most sensitive species to late frost and water …

Whether sources or sinks control wood growth remains debated with a paucity of evidence
from mature trees in natural settings. Here, we altered carbon supply rate in stems of mature …

Key message Woody tissue photosynthesis might play a key role in maintaining plant
carbon economy and hydraulic function under unfavourable conditions such as drought …

To investigate the climate impacts on the different components of ecosystem respiration, we
combined soil efflux data from a tree-girdling experiment with eddy covariance CO 2 fluxes …

Soil respiration (R s) is the largest outward flux of carbon (C) from terrestrial ecosystems,
accounting for more than half of total temperate forest C loss. Evaluating the drivers of this …

Carbon dynamics within trees are intrinsically important for physiological functioning, in
particular growth and survival, as well as ecological interactions on multiple timescales …

Stem CO 2 efflux (ES) plays an important role in the carbon balance of forest ecosystems.
However, its primary controls at the global scale are poorly understood and observation …

Soil respiration (R s) plays a key role in the carbon balance of forest ecosystems. There is
growing evidence that R s is strongly correlated with canopy photosynthesis; however, how …
