Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

High Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Tree Species Vulnerability to Fire Increases at Dry Range Edge

Global Change Biology Communications, Volume 1, Issue 4, December 2026.
Following severe drought and fire, some tree species experience increased tree mortality, topkill (death of above‐ground biomass) and lower rates of seedling recruitment at the dry edge of their ranges, while other species maintain resilience, exhibiting low rates of mortality and topkill and high rates of recruitment across their ranges.

Oxygen transmission rate in American oak barrel staves used for wine aging: Influence of wood macrostructure

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7844-7857, October 2026.
Abstract Background Oak barrels are widely used in wine and spirit aging, where oxygen transmission plays a key role in the development of chemical and sensory properties. In cooperage, stave selection is traditionally based on grain width; however, the extent to which grain and wood macrostructure determine oxygen transmission under barrel conditions ...

Hydraulic function of medullary bundles in a tropical root climber

American Journal of Botany, Volume 113, Issue 9, September 2026.
Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function in a tropical root climber, Adelobotrys scandens (Melastomataceae) to ...

Veratric Acid and the Cytotoxic Activity of Handroanthus impetiginosus Inner Bark Extract: No Association

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Physicochemical characterization, phytochemical profiling, and in vitro cytotoxicity assessment of Handroanthus impetiginosus inner bark extract show that veratric acid, despite being readily identified by HPLC‐DAD, does not account for the observed cytotoxicity.

Fungicidal Efficacy of Leaf Extracts From Khaya senegalensis (Desr.) A. Juss. Irrigated With Agricultural Drainage Water and Treated With Some Fertilizer Types

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
The extraction and analysis of K. senegalensis compounds for wood preservation. Air‐dried leaves are milled, soaked in ethanol, filtered, and concentrated into dried extracts. These extracts undergo HPLC for chemical profiling. The concentrated extract is applied to wood samples to test its antifungal activity, demonstrating its potential as a natural ...
