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.

Impregnation of Norway spruce (Picea abies L. Karst.) wood with hydrophobic oil [PDF]

, 2006
The overall goal of this thesis was to develop new knowledge to facilitate the production of Norway spruce wood-based materials that are more durable and more homogenous than current materials by using a hydrophobic oil impregnation process). Linseed oil

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 ...

Lignin studies of transgenic Norway spruce [PDF]

, 2006
An attractive objective in tree breeding is to reduce the content of lignin, or increase its extractability, to favor delignification during pulping. This study investigates the potential for lignin alterations in Norway spruce (Picea abies [L.] Karst ...

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 ...

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.

Seasonal measurements of total OH reactivity emission rates from Norway spruce in 2011 [PDF]

, 2013
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

Effects of silver fir (Abies alba Mill.) on the humus forms in Norway spruce (Picea abies (L.) H. Karst.) stands

Journal of Forest Science, 2018
The effects of silver fir (Abies alba Miller) on the soil compared to Norway spruce (Picea abies (Linnaeus) H. Karsten) were evaluated. Altitude of the study site is 790 m a.s.l., mild slope of 10° facing SW, forest site is spruce-beech on acid soil. The

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.
