Continuous Stem Water Potential Measurements of a Diffuse‐Porous Tree Species Offer New Insights Into Tree Water Relations

Ecohydrology, Journal Year: 2025, Volume and Issue: 18(1)

Published: Jan. 1, 2025

ABSTRACT Water potential is a crucial parameter for assessing tree water status and hydraulic strategies. However, methods measuring potential, such as the Scholander pressure chamber, are destructive, discontinuous difficult to perform in tall forests. Consequently, important dynamics potentials, particularly during short‐term drought, capture. Recent advancements have introduced low‐maintenance sensors capable of continuous, high‐resolution stem potentials. We evaluated these temperate, diffuse‐porous species ( Carpinus betulus ) over growing season marked by dry‐down periods heat. Measurements leaf sap flow environmental factors (air temperature, vapour deficit soil content) were conducted. Midday potentials C. reached minimum values −3.39 ± 0.10 MPa exhibited pronounced seasonal fluctuations, mirroring changes conditions flow. Stem correlated well with Scholander‐type measurements predawn R 2 = 0.98) but demonstrated an offset absolute midday 0.71) diurnal measurements. Minimum maximum expressed time lag showed distinct hysteresis. In this first assessment, agreement measurements, parameters suggests tested yield reliable data, especially predawn, need further validation conditions.

Early overyielding in a mixed deciduous forest is driven by both above- and below ground species-specific acclimation

Annals of Botany, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 23, 2024

Mixed forest plantations are increasingly recognised for their role in mitigating the impacts of climate change and enhancing ecosystem resilience. Yet, there remains a significant gap understanding early-stage dynamics species trait diversity interspecies interactions, particularly pure deciduous mixtures. This study aims to explore timing mechanisms by which competitive interactions influence yield, carbon allocation, space occupation mixed forests, both above- belowground.

Effects of heat, elevated vapor pressure deficits and growing season length on growth trends of European beech

Frontiers in Forests and Global Change, Journal Year: 2024, Volume and Issue: 7

Published: Dec. 9, 2024

In recent decades, continued growth decline has been observed in various beech forest regions of Central and Western Europe, especially the warmer lowlands, which is not necessarily linked to increased mortality. While earlier dendrochronological studies have shown that a deteriorating climatic water balance course climate warming can drive negative trends, less known about effects extremes on tree growth, notably heat rising atmospheric vapor pressure deficits (VPD). Through climate-growth analysis, we analyzed influence summer duration (frequency hot days with T max > 30°C) elevated VPD basal area increment (BAI) dominant trees 30 stands across precipitation gradient northern German lowlands. Summer (especially June) are reducing BAI similar manner as does deteriorated balance. growing season length (GSL), derived from thermal thresholds activity, substantially since 1980, declined majority stands, demonstrating decoupling productivity GSL. We conclude most likely important drivers this region, while lost its indicative value productivity.
