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

open access: yes, 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.

Developmental phase transitions in Norway spruce [PDF]

open access: yes, 2013
Plant development proceeds through distinct phases that are controlled by complex networks of regulatory genetic circuits and fine-tuned by environmental and endogenous cues.

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

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

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

open access: yesSilva 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.

Climate-growth relationships at different stem heights in silver fir and Norway spruce [PDF]

open access: yes, 2012
We investigated the effect of climate on variations in annual ring-area increment along the stem of dominant silver fir (Abies alba Mill.) and Norway spruce (Picea abies (L.) Karst.) trees in the Black Forest, southwestern Germany, to test the hypothesis

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

open access: yesiForest - 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 ...

Drought sensitivity of Norway spruce is higher than that of silver fir along an altitudinal gradient in southwestern Germany [PDF]

open access: yes, 2013
For Central Europe, climate projections foresee an increase in temperature combined with decreasing summer precipitation, resulting in drier conditions during the growing season.

The spruce bark beetle Ips typographus in a changing climate [PDF]

open access: yes, 2012
Outbreaks of the Spruce bark beetle Ips typographus are often triggered by storm and drought and have destroyed millions of cubic meters of wood. It is therefore a pest insect of economic importance in Europe.

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

open access: yesNotulae 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

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

open access: yesEvolutionary 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.
