AN EFFECT OF SPHAGNUM ON THE GROWTH OF BLACK SPRUCE [PDF]

The Forestry Chronicle, 1966
Black spruce (P. mariana (Mill.) BSP.) grows slowly and reproduces with difficulty on most of the lowland sites where it normally occurs. An examination of the rooting systems of small and large trees indicates that growth was initiated at points substantially below the present ground surface.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

Wildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Wood formation in black spruce : [PDF]

, 2012
La croissance des arbres dans la foret boreale est souvent consideree limitee par les basses temperatures et par la disponibilite en azote (N). Avec le rechauffement climatique, la disponibilite en azote pourrait augmenter grâce a l'effet positif d'une augmentation de la temperature du sol sur la mineralisation et la decomposition de la matiere ...

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

Wildlife Biology, EarlyView.
Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.

Effects of strands geometry on the physical and mechanical properties of oriented strand boards (OSBs) made from black spruce and trembling aspen

BioResources
Black spruce is widely used for lumber production in Eastern Canada, and it has the potential to replace trembling aspen and paper birch for oriented strand board (OSB) manufacturing.

Evaluating the impact of climate change on the black spruce defoliation by spruce budworm

, 2023
Current ecological models predict profound climate change-related effects on the natural disturbance regimes of forests. Spruce budworm (Choristoneura fumiferana) (SBW) is the principal insect defoliator in eastern North America, and SBW outbreaks have a major impact on the structure and function of the Canadian boreal forest, as defoliation leads to ...

Behavioral response of moose Alces alces to summer heat stress

Wildlife Biology, EarlyView.
Minnesota moose are heat‐stressed during summers, which is adversely impacting their survival. We used both movement and activity data to explore the behavioral responses of Minnesota moose experiencing heat stress, termed ‘hot moose events' or HMEs, to understand how both ambient temperature and available habitat contribute to the ability of these ...

Organic Material Dissolved During Oxygen-Alkali Pulping of Hot-Water-Extracted Spruce Sawdust

BioResources, 2016
Untreated and hot-water-extracted (HWE) Norway spruce (Picea abies) sawdust was cooked using the sulfur-free oxygen-alkali (OA) method under the following conditions: temperature, 170 °C; liquor-to-wood ratio, 5:1 L/kg; and NaOH charge, 19% on the oven ...

Life‐history stages and behavior influence demographic classification of moose captured on remote cameras

Wildlife Biology, EarlyView.
Obtaining accurate information on demographic states, such as the age and sex classes of animals, is an important step for monitoring wildlife populations. Traditionally, demographic data are collected from harvest, aerial surveys and telemetry studies.
