The Sequence of Drought‐Driven Stomatal Closure, Stem Xylem Embolism, Dehydration, and Aquaporin Gene Expression Differs Among Species

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Stem dehydration is critical in predicting drought‐driven tree mortality. Yet, how it coordinates with stomatal closure, xylem embolism, and aquaporin‐mediated water transport regulation remains unknown. Two angiosperms (beech and olive) and two conifers (pine and juniper) of contrasted embolism resistance were selected to assess the sequence ...

Large‐scale atmospheric variability entails differential modes of seasonal tree growth in the Mediterranean Basin

Journal of Ecology, Volume 113, Issue 9, Page 2652-2667, September 2025.
This work demonstrates the control of teleconnections on seasonal tree growth through local climate across the Mediterranean basin. Despite the constant link between the East Atlantic Pattern and temperature, synergies among teleconnections point to an east–west dipole in tree seasonal growth, driven by precipitation variability.

Multiyear Drought Strengthens Positive and Negative Functional Diversity Effects on Tree Growth Response

Global Change Biology, Volume 31, Issue 9, September 2025.
Mixed‐species forests may help trees better cope with increasing drought stress under climate change. We analyzed tree‐ring growth from nearly 1000 trees across 16 species in 9 experimental plantations across Europe to understand how tree diversity influences drought responses.

Age-related phenological and anatomical response of European beech (Fagus sylvatica L.) under severe summer drought conditions

Journal of Forest Science
The year 2018 was distinguished by a warm summer with extended periods of low or no precipitation. In this context, we investigated the intra-annual dynamics of xylem differentiation phases and quantitative vessel anatomy to analyse the age effect on the

Opposing seasonal trends in source water and sugar dampen intra‐annual variability in tree rings oxygen isotopes

New Phytologist, Volume 247, Issue 1, Page 97-114, July 2025.
Summary Variations of oxygen isotopes δ18O in tree rings provide critical insights into past climate and tree physiological processes, yet the mechanisms shaping the intra‐annual δ18O signals remain incompletely understood. To address this gap, we investigated how seasonal changes in source water, leaf water, and sugars influence δ18O recorded along ...

Carbon neutrality of forest biomass for bioenergy: a scoping review

iForest - Biogeosciences and Forestry, 2023
The exploitation of forest biomass for bioenergy is commonly perceived as part of a broad strategy for climate change mitigation due to the view that forest biomass is carbon neutral.

Ecological thresholds and transformations due to climate change: The role of abiotic stress

Ecosphere, Volume 16, Issue 4, April 2025.
Abstract An ecological threshold is the point at which a comparatively small environmental change triggers an abrupt and disproportionately large ecological response. In the face of accelerating climate change, there is concern that abrupt ecosystem transformations will become more widespread as critical ecological thresholds are crossed.

Highest Occurring Vascular Plants from Ladakh Provide Wood Anatomical Evidence for a Thermal Limitation of Cell Wall Lignification

Plant, Cell &Environment, Volume 48, Issue 2, Page 1445-1451, February 2025.
ABSTRACT As an evolutionary achievement of almost all terrestrial plants, lignin biosynthesis is essential for various mechanical and physiological processes. Possible effects of plant cell wall lignification on large‐scale vegetation distribution are, however, not yet fully understood. Here, we present double‐stained, wood anatomical stem measurements

A Coupled Model of Hydraulic Eco‐Physiology and Cambial Growth — Accounting for Biophysical Limitations and Phenology Improves Stem Diameter Prediction at High Temporal Resolution

Plant, Cell &Environment, Volume 48, Issue 2, Page 1344-1365, February 2025.
ABSTRACT Traditional photosynthesis‐driven growth models have considerable uncertainties in predicting tree growth under changing climates, partially because sink activities are directly affected by the environment but not adequately addressed in growth modelling.
