Antifungal properties of Norway spruce (Picea abies (L.) Karst.) seedling homogenates

Acta Societatis Botanicorum Poloniae, 2014
The presence of antimicrobials in root, hypocotyl and cotyledon homogenates of Norway spruce was studied using in vitro assays with soil-borne pathogens.

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Identification of Salt Stress Biomarkers in Romanian Carpathian Populations of Picea abies (L.) Karst.

PLoS ONE, 2015
The Norway spruce (Picea abies), the most important tree species in European forests, is relatively sensitive to salt and does not grow in natural saline environments.

Effect of soil waterlogging on below-ground biomass allometric relations in Norway spruce [PDF]

, 2010
An increasing importance is assigned to the estimation and verification of carbon stocks in forests. Forestry practice has several long-established and reliable methods for the assessment of aboveground biomass; however we still miss accurate predictors ...

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Forestry adaptation measures at the decline of Norway spruce (Picea abies Karst.) stands as exemplified by the Silesian Beskids, Czech Republic

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
At the beginning of this century, particularly after 2003, decline of Picea abies occurred at Forest District Jablunkov in the Silesian Beskids. This decline is of the complex character disease caused by the synergetic effects of abiotic, biotic and ...

Risk factors for bark stripping damage on Norway spruce by red deer

Wildlife Biology, EarlyView.
Norway spruce Picea abies is an economically important tree species in Europe, actively managed for forestry. Among the most negative biotic factors for growth and hence forest production is damage caused by wildlife, such as damage through bark stripping by red deer Cervus elaphus.

Screening Analyses of Pinosylvin Stilbenes, Resin Acids and Lignans in Norwegian Conifers

Molecules, 2006
The content and distribution of stilbenes and resin acids in Scots pine (Pinus sylvestris) and spruce (Picea abies), sampled in central Norway, have been examined. The contents of pinosylvin stilbenes in pine heartwood/living knots were 0.2-2/2-8 % (w/w).
