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,

Role of Mixed-Species Stands in Attenuating the Vulnerability of Boreal Forests to Climate Change and Insect Epidemics

Frontiers in Plant Science, 2021
We investigated whether stand species mixture can attenuate the vulnerability of eastern Canada’s boreal forests to climate change and insect epidemics.

Warming Drives Large‐Scale Shifts in Post‐Disturbance Vegetation Dynamics and Expansion of Deciduous Trees in the Boreal Forest in a Dynamic Vegetation Model

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract The intensification of disturbance regimes due to climate change is a growing concern in boreal forests, yet the long‐term consequences for forest recovery remain poorly understood, as boreal successional dynamics unfold over a century or longer and exceed the length of available observational records.

Spruce Budworm in Maine: 1977 [PDF]

, 1978
In May and June of 1977, the Maine Forest Service worked with the Cooperative Spruce Budworm Suppression Project to spray 922,000 acres of Maine forest as an attempt to manage the spruce budworm infestation.

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

, 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 ...

Three Centuries of Synchronous Forest Defoliator Outbreaks in Western North America.

PLoS ONE, 2016
Insect outbreaks often occur synchronously across large spatial scales, but the long-term temporal stability of the phenomenon and the mechanisms behind it are not well understood.

Carbon‐Nutrient Interactions Under Insect Disturbance Simulated by the Land‐Surface Model QUINCY 21edff48

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Insect outbreaks significantly impact tree mortality and carbon‐nutrient cycling in forest ecosystems, yet most terrestrial biosphere models do not represent insect disturbances due to the complexity of nutrient processes and limited data. To address this gap, we implemented a new insect impacts module in the QUINCY (Quantifying Interactions ...

Baculoviruses in populations of western spruce budworm

, 2015
Population studies of western spruce budworm, Choristoneura occidentalis, revealed that a baculovirus, ChocNPV, was widespread in outbreak populations over a broad geographical area of British Columbia, Canada although the rate of mortality was usually ...

Holocene reconstruction of the spruce budworm outbreak-fire interaction in the mixed boreal forest reveals a peculiar oscillation

Frontiers in Ecology and Evolution
Characterizing millennial and multi-millennial variability in disturbance regimes will be crucial in improving knowledge within the context of a changing climate and the development of sustainable forest management practices in the eastern Canadian mixed
