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: In this article, the authors highlight specific areas of recent progress and new research challenges in plant carbon and water relations, using selected examples covering scales from the leaf to the regional scale.

TL;DR: In this article, the effects of first natural rain pulses on soil and ecosystem carbon dioxide fluxes and their isotopic composition (delta C-13) after an extended summer drought in a Mediterranean oak woodland were monitored.

TL;DR: Stable isotopes provided valuable new insights into the drought-related variations of ecosystem C dynamics, encouraging future studies but also highlighting the need of improved methodology to disentangle short-term dynamics of isotopic composition of Reco.

TL;DR: Significant short-term dynamics in delta13C(R) at hourly to daily timescales and a modulated response to environmental drivers are indicated and may have important implications for the sampling protocols of nocturnal Keeling plots.
