Tree Mortality Risks Under Climate Change in Europe
General Context: Climate change can positively or negatively affect abiotic and biotic drivers of tree mortality. Process-based models integrating these climatic effects are only seldom used at species distribution scale. Objective: The…

Interaction of drought and frost in tree ecophysiology: rethinking the timing of risks
https://link.springer.com/article/10.1007/s13595-021-01052- Abstract • Key message The increase in climate variability is likely to generate an increased occurrence of both frost-induced and drought-induced damages on perennial plants. We examined how these stress factors…

Intra-specific variability in deep water extraction between trees growing on a Mediterranean karst
https://www.sciencedirect.com/science/article/pii/S002216942030888X Abstract Plant transpiration is a major component of water fluxes in the critical zone, which needs to be better characterized to improve our ability to understand and model the hydrological cycle.…

Distribution of endemic bark beetle attacks and their physiological consequences on Pinus halepensis
http://www.sciencedirect.com/science/article/pii/S0378112719324223 One factor that determines a tree’s resilience capacity to drought is its level of interaction with aggravating biotic factors, such as bark beetles, which in turn depends on whether insect populations…

Tree xylem water isotope analysis by Isotope Ratio Mass Spectrometry and Laser Spectrometry: a dataset to explore tree response to drought
http://www.sciencedirect.com/science/article/pii/S2352340920302432 Water isotopes from plant xylem and surrounding environment are increasingly used in eco-hydrological studies. Carrière et al. [1] analyzed a dataset of water isotopes in (i) the xylem of three different tree…
