Host preferences of non‐native Acalolepta aesthetica (Coleoptera: Cerambycidae) on the Island of Hawaiʻi

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 2, Page 149-159, May 2026.
Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...

Investigating the Chemical, Antifungal, and Cytotoxic Properties of Cochlospermum vitifolium Leaves and Stem Bark Extracts

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
This figure contains images created by Freepik from Flaticon. ABSTRACT Comprehensive analysis of the chemical properties and bioactivities of plant extracts is essential for identifying compounds with therapeutic potential. This study analyzed hydroethanolic extracts from the leaves and stem bark of Cochlospermum vitifolium, investigating their ...

Flammability behaviour of wood and a review of the methods for its reduction [PDF]

open access: yes, 2013
Wood is one of the most sustainable, aesthetically pleasing and environmentally benign materials. Not only is wood often an integral part of structures, it is also the main source of furnishings found in homes, schools, and offices around the world.

Nirs tools for prediction of main extractives compounds of teak (Tectona grandis L.) heartwood [PDF]

open access: yes, 2012
Biochemical and physiological process which occurred during heartwood formation have consequences on wood properties such as colour, natural durability and some mechanical properties. However, it is very time-consuming to take measurements of extractives

Artefacts Associated With Cryogenic Vacuum Distillation Do Not Compromise Plant Source Water Extraction From Soil and Xylem for Isotope Analysis

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Understanding the oxygen and hydrogen isotopic composition (δ18O and δ2H values, respectively) of plant source water is fundamental for tracing water uptake in ecohydrological studies. However, discrepancies between cryogenic vacuum distillation (CVD)‐extracted soil and xylem water and known plant source water δ18O and δ2H values continue to ...

Living on borrowed time – Amazonian trees use decade‐old storage carbon to survive for months after complete stem girdling [PDF]

open access: yes, 2018
Nonstructural carbon (NSC) reserves act as buffers to sustain tree activity during periods when carbon (C) assimilation does not meet C demand, but little is known about their age and accessibility; we designed a controlled girdling experiment in the ...

Using Radon (222Rn) to Trace Variability in Greenhouse Gas Emission From Tree Stems Across Species, Seasons and Stem Heights

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

Diterpenoid Diversity across Land Plants

open access: yesHelvetica Chimica Acta, Volume 109, Issue 4, April 2026.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

A Generic Spinup Procedure to Initialize European Forest State Variables in Land Surface Models

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Forest structure is shaped by forest management practices, land‐use changes, and natural disturbances, including droughts, fires, storms, and insect outbreaks that drive species‐specific and size‐specific mortality. By modifying the carbon‐water‐energy exchanges with the atmosphere, it influences a stand's capacity to buffer against or succumb

New Insights on Wood Dimensional Stability Influenced by Secondary Metabolites: The Case of a Fast-Growing Tropical Species Bagassa guianensis Aubl. [PDF]

open access: yesPLoS ONE, 2016
Challenging evaluation of tropical forest biodiversity requires the reporting of taxonomic diversity but also the systematic characterization of wood properties in order to discover new promising species for timber industry.
