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

Beginning in the early 1990s, the balsam fir sawfly (Neodiprion abietis) became a significant defoliating insect of precommercially thinned balsam fir (Abies balsamea (L.) Mill.) stands in western Newfoundland, Canada.

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

Forecasting ecological trajectories from ecological dynamic regimes to improve resilience analysis
Abstract The ecological dynamic regime (EDR) framework was recently proposed as an alternative to equilibrium‐based approaches for assessing ecological resilience in empirical systems, explicitly incorporating dynamic regimes as a reference for assessing the system's deviation during disturbances.

Balsam Fir in front of Nininger Hall
A Balsam Fir, Abies balsamea (Pinaceae) was in the lawn in front of Nininger Hall near East College Street across from the Kline Campus Center, late 1970’s.https://digitalcommons.bridgewater.edu/college_landscapes/1019/thumbnail ...

Often termed “acid rain,” combined nitrogen and sulfur deposition can directly and indirectly impact the condition and health of forest ecosystems. Researchers use critical loads (CLs) to describe response thresholds, and recent studies on acid‐sensitive

ABSTRACT Aim Northern populations of temperate tree species evolve under climatic, topographic and edaphic conditions that approach the limits of their ecological tolerance. However, the environmental constraints acting on species abundance are not spatially uniform, and their relative importance can shift markedly from core to northern populations. We

Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

This study discovered CfHSP70‐2, a heat shock protein expressed in the testis of a forest lepidopteran pest spruce budworm, Choristoneura fumiferana, during late pupal and adult stages primarily found in round spermatids during spermatogenesis. Heat shock, starvation, and chemical heat shock protein activators were unable to alter expression.
