Finalisation of the European Approach to Assess the Fire Performance of Facades—Brief Information on the Outcome of the Project

Fire and Materials, EarlyView.
ABSTRACT This research was conducted within the framework of project SI2.825082, funded by the European Commission—DG GROW. The project's objective was to finalise a European approach for assessing the fire performance of façades under medium and large fire exposure conditions.

Changes in the extent and structure of Norway spruce stands in the Ukrainian Carpathians based on forest survey data from 1988 to 2018

Central European Forestry Journal
This study investigates dynamics of Norway spruce stands in the Ukrainian Carpathians in 1988–2018. Cultivation of Norway spruce has altered forest composition at the expense of site-adapted species.

Difference on cone size preferences between two coniferous species by Great Spotted Woodpecker (Dendrocopos major) [PDF]

PeerJ, 2017
The number of species that specialize in pre-dispersal seed predation is relatively small. Examples of specialized pre-dispersal seed predators adapted to feeding on closed cones include vertebrate species like Crossbills, Squirrels, Nutcrackers and ...

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Recruitment dynamics in conifer-dominated uneven-aged forests in the carpathians

Forest Ecosystems
In permanently uneven-aged forests, continuous ingrowth of recruitment into higher stand layers is a critical process for the formation and maintenance of differentiated stand structures.

Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

Oikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

Species selection in areas subjected to risk of root and butt rot: applying Precision forestry in Norway

Silva Fennica, 2022
Norway’s most common tree species, Picea abies (L.) Karst. (Norway spruce), is often infected with Heterobasidion parviporum Niemelä & Korhonen and Heterobasidion annosum (Fr.) Bref.. Because Pinus sylvestris L.
