Repellent Effects of Host Essential Oils and Limited Effects of Host Length on Tree‐Killing Bark Beetle Attacks

Entomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 37-44, January 2026.
This study demonstrated that the host essential oil significantly reduced Polygraphus proximus Blandford (Coleoptera: Scolytinae) attack density, but the density did not differ significantly among logs of various lengths of Abies sachalinensis. Our study suggests that host essential oils can perform as repellents against conifer‐infesting bark beetles.

Habitat Mosaic Limits Gene Flow and Promotes Morphological Adaptation in a Generalist Mammal

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We investigated how fine‐scale habitat heterogeneity influences genetic structure in the European wood mouse by sampling individuals across hedgerow, forest edge, and inner forest habitats in three Northern Ireland forest parks. Microsatellite and stable isotope analyses revealed consistent genetic divergence and dietary differences among habitat types,

STUDIES ON THE PIGMENT FROM HEART WOOD OF LARIX KAEMPFERI

Journal of the Japanese Technical Association of the Pulp and Paper Industry, 1952
The saw dust from heart wood of Larix Kaempferi was extracted in a continuous extraction with methanol for 7 days. Brownish red extract was evaporated, and yield a brownish red mass. It treated with hot water, then afforded a yellowish white crystal. After several times of recrystallzation from hot water with charcoal, it gave hexagonal sheet crystal ...

Soil pH modulates microbial nitrogen allocation in soil via compositional and metabolic shifts across forests in Japan

iMetaOmics, Volume 2, Issue 4, December 2025.
This study reveals how soil pH regulates microbial N allocation in forest soils across Japan. We show that microbial abundance controls the overall rate of N cycling, while microbial composition and metabolic potential determine whether ammonium is released or retained.

Transcriptomics of Three Larix Species in Response to Geographically Distinct Bursaphelenchus xylophilus Strains in China

Plants
Pine wood nematode (PWN, Bursaphelenchus xylophilus) is fatal to the pine trees around the world. Its northward and westward expansion in China endangers Larix spp., yet its molecular response remains understudied.

Evaluating the accuracy of the Seek app for conifer identification: A baseline for future educational use

Natural Sciences Education, Volume 54, Issue 2, December 2025.
Abstract In recent years, mobile applications, including artificial intelligence‐based ones such as Seek by iNaturalist, have become essential educational tools, particularly for science and outdoor learning. Therefore, we decided to work with this mobile app and conduct a pilot investigation of its reliability in selected conifer species ...

Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues

Plant, Cell &Environment, Volume 48, Issue 12, Page 8483-8501, December 2025.
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...

Pest categorisation of Guignardia laricina

EFSA Journal, 2018
Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of Guignardia laricina, a well‐defined and distinguishable fungal species of the family Phyllostictaceae.

Transcriptomic and enzymological evidence for plastid peptidoglycan synthesis in the gymnosperm Picea abies

The Plant Journal, Volume 124, Issue 5, December 2025.
Significance Statement Peptidoglycan (murein) biosynthesis is involved in chloroplast division in mosses, while Arabidopsis MurE mutants are defective in chloroplast development. We have shown that the gymnosperm Picea abies expresses 11 genes of the peptidoglycan biosynthesis pathway, and that P.

What Risk Does Phytophthora ramorum Pose to Sitka Spruce (Picea sitchensis) and Other Conifers in Britain?

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Larch (Larix) and, to a lesser extent, rhododendron (Rhododendron ponticum) have emerged as key drivers of the Phytophthora ramorum epidemic in Britain because of the copious numbers of sporangia that are released from their foliage following infection; the inoculum then initiates stem and foliar infections on nearby broadleaf and conifer ...
