Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe

open access: yesPlant Biology, EarlyView.
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Redistribution of soil water by mature trees towards dry surface soils and uptake by seedlings in a temperate forest

open access: yesPlant Biology, EarlyView.
Mature beech trees redistributed soil water, equal to ca. 10% of stand transpiration, from deeper moist soils to dry surface soils, where it was taken up by seedlings of different tree species. Abstract Hydraulic redistribution is considered a crucial dryland mechanism that may be important in temperate environments facing increased soil drying–wetting
