Long-term effects of precommercial thinning on the stem dimensions, form and branch characteristics of red spruce and balsam fir crop trees in Maine, USA

Silva Fennica, 2009
The effects of precommercial thinning (PCT) on stem dimensions, form, volume, and branch attributes of red spruce [Picea rubens Sarg.] and balsam fir [Abies balsamea (L.) Mill.] crop trees were assessed 25 years after treatment in an even-aged ...

Long‐term trends in greenness in the alpine zone of northeastern North America from remote sensing

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Alpine zones above treeline in the Appalachian Mountains and adjacent ranges of northeastern North America support distinctive ecological communities that thrive where conditions are too harsh for trees to grow. These communities differ from alpine zones elsewhere on the continent and are a regionally important source of floristic biodiversity,

COMPATIBILITY OF FOUR EASTERN CANADIAN WOODS WITH GYPSUM AND GYPSUM-CEMENT BINDERS BY ISOTHERMAL CALORIMETRY COMPATIBILIDAD DE CUATRO MADERAS DEL ESTE DE CANADÁ CON YESO Y YESO-CEMENTO POR CALORIMETRÍA ISOTÉRMICA

Maderas: Ciencia y Tecnología, 2008
In order to determine the feasibility of manufacturing wood-gypsum and wood-gypsum-cement particleboards, the hydration reactions of four Eastern Canadian wood species with gypsum and Portland cement were studied. The compatibility of hot water extracted

Investigating climate anomalies associated with the sudden mortality of balsam fir trees in eastern Canada

Frontiers in Forests and Global Change
The identification of climate anomalies associated with large-scale stand disturbances can help inform climate-focused forest management. In the spring and summer of 2018, an unusual spike in balsam fir (Abies balsamea) mortality was reported in multiple

Interactions entre le type de plants et la sylviculture dans la restauration de sapinières sous forte pression de broutement

The Forestry Chronicle, 2019
Les herbivores transforment les ecosystemes, particulierement suite aux introductions en milieux insulaires. La plantation de sapins baumiers (Abies balsamea) est realisee sur l’ile d’Anticosti (Quebec, Canada) pour restaurer ou maintenir des composantes

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

Wildlife Biology, Volume 2026, Issue 5, September 2026.
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 ...

The overlooked role of individual variability in autumn xylem phenology and carbon sequestration

Forest Ecosystems
Accurate modeling of carbon sequestration by forests requires scaling wood formation processes from trees to the landscape. The quantification of growth and carbon dynamics requires deep knowledge of the variability in xylem phenology among individuals ...

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

Wildlife Biology, Volume 2026, Issue 5, September 2026.
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.

Age and size structure of gap-dynamic, old-growth boreal forest stands in Newfoundland

Silva Fennica, 2006
The age and size structure of trees in old Abies-Picea-Betula forests on Newfoundland’s Great Northern Peninsula were examined. It was hypothesized that the size and age structure of both the tree and regeneration “strata” of these stands ...
