Potential relationships of selected abiotic variables, chemical elements and stand characteristics with soil organic carbon in spruce and beech stands

iForest - Biogeosciences and Forestry, 2021
Increasing attention is given to carbon sequestration in forest soil with regard to climate change and the mitigation of its impacts; therefore, it is very important to know which parameters and variables could influence carbon sequestration and throw ...

Terpenoids are transported in the xylem sap of Norway spruce [PDF]

Plant, Cell & Environment, 2020
Norway spruce is a conifer storing large amounts of terpenoids in resin ducts of various tissues. Parts of the terpenoids stored in needles can be emitted together with de novo synthesized terpenoids. Since previous studies provided hints on xylem transported terpenoids as a third emission source, we tested if terpenoids are transported in xylem sap of

Effects of Volatile Emissions of Picea abies Fresh Debris on Ips duplicatus Response to Characteristic Synthetic Pheromone

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2012
Ips duplicatus is an important pest of Norway spruce (Picea abies) planted outside of its natural range. This species uses olfactory signals to identify the spruce trees favourable for colonisation. The knowledge of the beetles’ response to these stimuli

Nutrient dynamics and early decomposition rates of Picea abies needles in combination with Fagus orientalis leaf litter in an exogenous ecosystem

Annals of Forest Research, 2016
The Hyrcanian forests in the Northern Iran are originally poor of coniferous and are considered as a refugium of temperate broad-leaved trees during the Quaternary glaciations.

Divergent selection predating the Last Glacial Maximum mainly acted on macro‐phenotypes in Norway spruce

Evolutionary Applications, 2023
The current distribution and population structure of many species were, to a large extent, shaped by cycles of isolation in glacial refugia and subsequent population expansions.

Stem taper and bark functions for Norway spruce in Norway [PDF]

Silva Fennica, 2019
Based on data from long-term experimental fields with Norway spruce ( (L.) H. Karst.), we developed new stem taper and bark functions for Norway. Data was collected from 477 trees in stands across Norway. Three candidate functions which have shown good performance in previous studies (Kozak 02, Kozak 97 and Bi) were fitted to the data as fixed-effects ...

Coccinellidae on native and introduced spruce in central Europe: conservation implications in urban areas

Frontiers in Ecology and Evolution
The abundance and species composition of adult ladybird communities (Coleoptera: Coccinellidae) were investigated on two congeneric trees, native Norway spruce (Picea abies) and the introduced blue spruce (Picea pungens), at four locations in Slovakia ...

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.

Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content

Fire and Materials, EarlyView.
ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

Ectomycorrhizas and cadmium toxicity in Norway spruce seedlings [PDF]

Tree Physiology, 1999
We studied the effects of ectomycorrhizal colonization by Laccaria bicolor (Maire) Orton S238 and Paxillus involutus (Batsch) Fr. 533 on cadmium (Cd) toxicity in Norway spruce seedlings (Picea abies (L.) Karst.). Both mycorrhizal and nonmycorrhizal seedlings were exposed to 0 (control), 0.5 or 5 &mgr;M CdSO(4) for 9 weeks in a sand culture system with ...
