Air pollution and its multifaceted effects on insect pollinators: A review

Ecological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.
Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

LiDAR‐derived forest inventory data to map and quantify ecologically important large trees across large spatial extents

Ecological Applications, Volume 36, Issue 1, January 2026.
Abstract Large old trees are widely recognized as ecologically important across forest landscapes and concern regarding the decline of these trees is well documented because of their role in maintaining biodiversity for a broad range of organisms. In response to a growing need to inventory such trees, we developed and present the methodology to map and

Modeled diameter growth response to intermediate treatments of planted white spruce (Picea glauca) affected by eastern spruce budworm (Choristoneura fumiferana) in Minnesota, USA

, 2019
White spruce (Picea glauca (Moench) Voss) plantations have historically been an important source of high-quality forest products in the Great Lakes Region of North America.

Resist!: Sustaining forest carbon sequestration and wood production after insect disturbance

Frontiers in Ecology and the Environment, Volume 23, Issue 10, December 2025.
Disturbances from insect pests threaten ecologically and economically important goods and services supplied by forests, including wood production and carbon sequestration. We highlight the factors that influence these services’ resistance, a term quantifying the initial response to disturbance.

Variation in the Molecular Phenotype of βglu‐1, an Insect Defence‐Related Beta‐Glucosidase Gene, in Two Transcontinental Picea Species

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Forest trees face threats from many insect pest species, underscoring the importance of understanding their defence mechanisms for survival. In a North American conifer species, Picea glauca, gene expression of βglu‐1 produces phenolic compounds (acetophenones) that defend against its insect defoliator, Choristoneura fumiferana. βglu‐1 is also

Pre-ingestive effects of tannins on the spruce budworm, Choristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae) [PDF]

, 2007
The spruce budworm, Choristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae), is considered the most important pest threatening the coniferous forests of eastern North America.

International Biological Flora: Tsuga canadensis*

Journal of Ecology, Volume 113, Issue 10, Page 3037-3080, October 2025.
Eastern Hemlock is a long‐lived forest tree of eastern North America known for its deep shade and home given to many organisms. Despite surviving large‐scale clearing for agriculture when Europeans arrived, it returned to dominate when the land was abandoned in the mid 1800s.

Diapause survival requires a temperature-sensitive preparatory period

Current Research in Insect Science
Diapause is a form of internally-controlled dormancy that allows insects to avoid stressful conditions and periods of low food availability. Eastern spruce budworm (Choristoneura fumiferana Clemens), like many cold-adapted insects, enter diapause well in

Leveraging Biomass Procurement to Mitigate Carbon Emissions at the Stand Level: A Case Study in Eastern Canadian Forests

GCB Bioenergy, Volume 17, Issue 9, September 2025.
The carbon emission reductions from using residual forest biomass for bioenergy remain controversial, despite its potential to mitigate climate change. This study evaluated how intensifying wood procurement for bioenergy, alongside supplying fiber for conventional wood industries, can support low‐carbon forest management.
