Context: The increase in drought intensity due to climate change will accentuate the risk of tree mortality. But very few process-based models are currently able to predict this mortality risk. Aims: We describe the operating principle of a new mechanistic model SurEau that computes the water...

Low water-holding properties impose dry conditions on plants on serpentine soil. To test the hypothesis that leaf water relations are key plant characteristics to grow in serpentine soil, we compared these traits for four tree species (Quercus serrata, Clethra barbinervis, Magnolia obovata and ...

Mature oak stands of different tree height at four sandy valley river sites (Quercus robur) and one south-exposed schist slope (Qu. petraea) in the middle Rhine and lower Main valley were studied from early summer 2017 (normal wet year) until the end of 2018 (extremely hot and dry year). Tree water ...

Despite the appeal of the iso/anisohydric framework for classifying plant drought responses, recent studies have shown that such classifications can be strongly affected by a plant's environment. Here, we present measured in situ drought responses to demonstrate that apparent isohydricity can be...

In this issue of New Phytologist, Ramírez-Valiente et al. (2020; pp. 794-809) used a common garden experiment to assess whether leaf traits, whole-plant morphology, plant hydraulics, gas exchange, and growth rates have evolved in coordination in 12 oak (Quercus) species from the western Palearctic...

We investigated the effects of historic soil chemistry changes associated with acid rain, i.e., reduced soil pH and a shift from nitrogen (N)- to phosphorus (P)-limitation, on the coordination of leaf water demand and xylem hydraulic supply traits in two co-occurring temperate tree species...

Climate change might impact tree fecundity by altering the relative influences of meteorological and physiological drivers, and by modifying resource investment in reproduction. Using a 13-yr monitoring of Quercus ilex reproduction in a rainfall exclusion experiment, we analysed the interactive...

The determinations carried out between July and September 2021 in the Comanesti Hills aimed to establish the effect of the prolonged drought in this area on the physiological processes in the young trees of the species Quercus cerris, Q. Robur and Q. freinetto. The results obtained showed that all...

Szczepkamyces, typified by Szczepkamyces campestris, was a monotypic genus. Based on distinct morphological characters and phylogeny inferred from the combined 2-locus dataset [ITS1-5.8S-ITS2 (ITS) + nuclear large subunit RNA (nLSU)], another species of the genus, Szczepkamyces quercicola sp. nov., ...

A user-friendly and affordable broad-band digital Near Infrared (NIR) camera (Canon PowerShot S110 NIR) was compared with a narrow-band reflectance spectrometer (USB2000, Ocean Optics) at leaf scale for monitoring changes in response to drought of three ecologically contrasting Quercus species (Q....
