TL;DR: In 2018, Central Europe experienced one of the most severe and long-lasting summer drought and heat wave ever recorded, which had a greater impact on forest ecosystems of Austria, Germany and Switzerland than the 2003 drought as discussed by the authors.

TL;DR: In this paper, the authors present data from an experimental field study using straight-forward stable isotope methodology to gather new insights into the processes induced by rewetting of dried soils and evaluate current hypotheses for the “Birch“-CO 2 -pulse.

TL;DR: Evergreen sclerophylls were less susceptible to photoinhibition, and the diurnal decline in F-v/F-m remained fully reversible during drought, and structural regulation of light interception was not found to be an important strategy in these species, and only small, though significant changes in leaf angle occurred.

TL;DR: A review of water ages in the critical zone can be found in this article, where the authors provide an overview of new prospects and challenges in the use of hydrological tracers to study water ages, and a discussion of the limiting assumptions linked to our lack of process understanding and methodological transfer of water age estimations to individual disciplines or compartments.

TL;DR: Chronic and total photoinhibition were significantly correlated with predawn and midday water potentials, respectively, and a grouping of the macchia species into three functional groups is proposed according to this relationship.
