Total Ozone Reactivity Measurements Reveal Knowledge Gap in Volatile Organic Compound Emissions and Their Reactions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Total ozone (O3) reactivity monitors (TORMs) were used to investigate biogenic volatile organic compound (BVOC) emissions from several ecosystems. Measurements were conducted in temperate deciduous North American forests, during the CABINEX and SOAS campaigns, on tundra vegetation emissions at Toolik lake field station (TFS) in Alaska, and in ...

Effects of brassinosteroid application on seed germination of Norway spruce, Scots pine, Douglas fir and English oak

iForest - Biogeosciences and Forestry, 2017
We tested the influence of a synthetically-produced brassinosteroid compound (2α,3α,17βtrihydroxy-5α-androstan-6-one) on seed germination in Norway spruce, Scots pine, Douglas fir and English oak.

Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, Volume 2026, Issue 8, August 2026.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

Ectomycorrhizal community composition and extramatrical hyphal proportion predict soil carbon stocks at the landscape scale

Functional Ecology, Volume 40, Issue 8, Page 2490-2505, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While fungal composition has been linked to soil carbon at global scales, these patterns are often difficult to disentangle from broad climatic gradients and species range limits. To address this constraint, we tested which aspects of ectomycorrhizal community structure

Regeneration response to post‐disturbance forest management in Central Europe

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
As disturbance activity intensifies, forest management must identify strategies to facilitate the rapid recovery of disturbed sites. By studying 868 disturbed sites across Central Europe, we found that active post‐disturbance management significantly enhanced tree regeneration in regional disturbance hotspots.

Risk assessment of mould growth on spruce wood during transport in an intermodal container

Maderas: Ciencia y Tecnología, 2018
Microclimatic conditions (relative humidity and temperature) were monitored in a shipment of Norway spruce (Picea abies) wood inside an intermodal container on its 66-day transport from Slovenia to Japan. In parallel, the susceptibility of Norway spruce

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 382-397, August 2026.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Tensile creep of Norway spruce on the tissue scale

Mechanics of Time-Dependent Materials
Abstract The rheological behavior of wood emerges from complex mechanical interactions occurring across multiple length scales. This behavior is characterized by directional dependence, as well as sensitivity to moisture content, loading time, and the degree of loading.

Competitive interactions modify the direct effects of climate

Ecography, Volume 2026, Issue 8, August 2026.
As the climate is changing, species respond by changing their distributions and abundances. The effects of climate are not only direct, but also occur via changes in biotic interactions, such as competition. Yet, the role of competition in mediating the effects of climate is still largely unclear.
