Predation by Amphibians and Small Mammals on the Spruce Budworm (Lepidoptera: Tortricidae)

, 2017
Stomach-content analyses of pitfall-trapped amphibians and small mammals showed that the eastern American toad, Bujo americanus americanus, and the wood frog, Rana sylvatica, preyed on late instars and moths of the spruce budworm, Choristoneura ...

Modeling stratified dispersal in forest pests: A case study of the mountain pine beetle in Alberta

Ecology, Volume 107, Issue 2, February 2026.
Abstract Forest pests pose critical threats to forest ecosystems worldwide, yet accurately predicting their spatial spread remains challenging due to complex dispersal behaviors, weather effects, and the inherent difficulty of tracking small organisms across large landscapes.

Perceptions of Spruce Budworm Monitoring, Management, and Remote Sensing Technology in Maine's Forest Sector

Maine Policy Review
Eastern spruce budworm (Choristoneura fumiferana Clem; SBW) is a native forest pest that can severely damage spruce-fir forests in Maine. Monitoring SBW defoliation and populations is important to ensure forest managers make timely decisions regarding ...

Spruce Budworm Defoliation Influences Greenhouse Gas Concentrations in Streams

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract One of the most significant natural disturbances in the Canadian boreal and hemiboreal forest is tree defoliation by eastern spruce budworm (SBW), which may increase nutrient and carbon inputs to catchment soils, and in runoff. Closely connected to catchments, headwater streams are known to be significant emitters of greenhouse gases (GHGs ...

Changes in Spatiotemporal Patterns of 20th Century Spruce Budworm Outbreaks in Eastern Canadian Boreal Forests

Frontiers in Plant Science, 2018
In scenarios of future climate change, there is a projectedincrease in the occurrence and severity of natural disturbances inboreal forests. Spruce budworm (Choristoneura fumiferana)(SBW) is the main defoliator of conifer trees in the North American ...

Ecological factors shaping post‐fire resilience in mature black spruce forests of eastern North America

Journal of Ecology, Volume 114, Issue 2, February 2026.
Our study provides an assessment of the fire resilience of mature black spruce (BS) forests. A third of pre‐fire mature closed‐canopy stands are expected to transition into open woodlands. While mature BS‐dominated forests are considered more fire‐resilient than younger stands, our study raises concerns about their capacity to persist under the ...

Come from away: Reconstructing a long‐range migratory flight of spruce budworm moths to Newfoundland, Canada Venues de loin : reconstitution d'un vol migratoire de longue distance de tordeuses des bourgeons de l'épinette vers Terre‐Neuve, au Canada

Ecological Entomology, Volume 51, Issue 1, Page 41-58, February 2026.
Lagrangian atmospheric models were used in conjunction with ecophysiological factors to reconstruct the path and meteorological conditions of a long‐range migration flight of spruce budworm moths to Newfoundland, Canada. Moths travelled under high winds and warm temperatures that favoured their migratory flight until encountering cooler temperatures ...

Evaluating the efficacy of eBird data for modeling historical population trajectories of North American birds and for monitoring populations of boreal and Arctic breeding species

Avian Conservation and Ecology, 2020
Historic population trajectories for most North American bird species are largely unknown for years prior to circa 1970. Additionally, current estimates of population trajectories of boreal and Arctic breeding species are imprecise or biased because of ...
