Ecological results of Norway spruce forests’ decline in main forest types of the Ukrainian Carpathians

Наукові праці Лісівничої академії наук України, 2019
Stationary studies of the decline dynamics on the 21st Norway spruce forest stands in the Ukrainian Carpathians were conducted in 2010-2014. The analysis of the research results made it possible to assess the environmental impacts of their decline for ...

The crown condition of Norway spruce and occurrence of symptoms caused by Armillaria spp. in mixed stands

Journal of Forest Science, 2020
Mixed stands are currently supported as effective management options to reduce forest vulnerability to climate change. However, our issues about benefits of mixtures, mechanisms of their incidence and conditions for their effectiveness have yet been only

Dynamics of soil organic carbon (SOC) content in stands of Norway spruce (Picea abies) in central Europe

iForest - Biogeosciences and Forestry, 2018
Norway spruce is the main forest tree species in the Czech Republic. Until now, little attention has been given in the literature to the dynamics of soil organic carbon (SOC) content under Norway spruce stands as a function of stand characteristics.

Effects of field vegetation control on pine weevil (Hylobius abietis) damage to newly planted Norway spruce seedlings [PDF]

, 2003
We investigated interactions between field vegetation and seedling damage caused by a major insect pest, the pine weevil Hylobius abietis (L.), in an experiment established on a clear-cut area in southern Sweden.

Transmittance of young Norway spruce stand canopy for photosynthetically active radiation during the growing season

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
Analysis of transmittance of young Norway spruce stand canopy for photosynthetically active radiation (PAR) was made at the study site of Bílý Kříž (the Moravian-Silesian Beskids Mts., the Czech Republic) at different sky conditions during the growing ...

Control efficacy of stump treatment and influence of stump height on natural spore infection by Heterobasidion spp. of precommercial thinning stumps of Norway spruce and birch

Silva Fennica, 2012
An alternative precommercial thinning technique results in trees being cut higher up the stem compared to the normal method using a brush saw. The aims of this study were to investigate if primary infection of Heterobasidion spp.

Potential implications of shortened rotation length for forest birds, bryophytes, lichens and vascular plants: An example from southern Swedish production forests.

PLoS ONE, 2023
The rotation lengths of intensively managed production forests may be altered to achieve a variety of goals, with correspondingly implications for biodiversity.

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
AbstractNorway 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 ...

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.
