Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought

Plant, Cell &Environment, Volume 49, Issue 8, Page 4850-4871, August 2026.
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.

Decreasing water availability reduces productivity in Swiss forests along an altitudinal gradient

Functional Ecology, Volume 40, Issue 7, Page 2143-2157, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests are one of the most important terrestrial carbon sinks, but are increasingly under pressure due to drought, heat and the occurrence of extreme events. There are opposing longer term trends for European forest growth reported, and severe drought and disturbance ...

Regulating bark beetles with mechanical bark treatments: Trade‐offs among pest control, operational efficiency and biodiversity

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Three times harvester processing and motor‐manual bark gouging effectively reduce bark beetles, enabling two options: permanent on‐site retention for biodiversity conservation, or up to 2 years of intermediate on‐site storage with no treatment effect on blue‐stain fungi colonization or energy content, thereby buffering operational bottlenecks during ...

Sapwood Cuts and Their Impact on Tree Stability

Arboriculture & Urban Forestry, 2012
AbstractSapwood may be lost due to wood decay fungi or mechanical damage. Assessing the impact of sapwood loss on the likelihood of tree failure has not been empirically tested. The purpose of this research was to determine the effect of the loss of sapwood on the flexural stiffness of tree trunks for different species and trunk sizes.

Bayesian Approach to Sapwood Estimates and Felling Dates in Dendrochronology [PDF]

Archaeometry, 2002
An improved method of generating sapwood estimates for oak is developed. This suggests a revision of the 95% confidence range from 10–40 to 9–36 rings for trees from southern England. Current methods for estimating felling dates on timbers with incomplete sapwood do not generate true 95% confidence limits, and a Bayesian method for deriving such limits

Effects of heat treatment on the physical properties of heartwood and sapwood of Cedrus libani [PDF]

BioResources, 2013
Effects of heat treatment on the physical properties of heartwood and sapwood of Cedrus libani A. Richard, such as density, equilibrium moisture content, swelling, and fiber saturation point were investigated.

Effects of moisture content on the behaviour of Scots pine heartwood and sapwood under impact

Journal of Wood Science
The material properties of sapwood and heartwood vary within various wood species and even they can show significant differences within a single tree. Scots pine (Pinus sylvestris L.), a species that plays a crucial role in timber production for joinery ...

Heartwood and sapwood in eucalyptus trees: non-conventional approach to wood quality

Anais da Academia Brasileira de Ciências
This study evaluated the quality of heartwood and sapwood from mature trees of three species of Eucalyptus, by means of the qualification of their proportion, determination of basic and apparent density using non-destructive attenuation of gamma ...
