Breaking the ice: multiple origins of ice‐binding/antifreeze proteins
The FEBS Journal, EarlyView.Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.

Protection Strategy against Spruce Budworm
, 2019 Spruce budworm is one of the most significant forest insects worldwide, in terms of outbreak extent, severity, and economic impacts. As a defoliator, spruce budworm larvae are susceptible to insecticide protection, and improvements in efficacy and ...

Soil Science Society of America Journal, Volume 90, Issue 6, November/December 2026.Abstract Soils of managed boreal forests are a significant carbon (C) reservoir, and maintaining or increasing their ability to store C could play an important role for climate change mitigation. We investigated the effects of forest logging through clearcut and partial cut compared to forest conservation on total soil C stocks, particulate organic ...

Vulnerability of conifer regeneration to spruce budworm outbreaks in the Eastern Canadian boreal forest [PDF]
, 2019 Spruce budworm (Choristoneura fumiferana) is the main defoliator of conifer trees in North American boreal forests, affecting extensive areas and causing marked losses of timber supplies. In 2017, spruce budworm affected more than 7 million ha of Eastern

Variation of Stem Radius in Response to Defoliation in Boreal Conifers
Frontiers in Forests and Global Change, 2021 In the long term, defoliation strongly decreases tree growth and survival. Insect outbreaks are a typical cause of severe defoliation. Eastern spruce budworm (Choristoneura fumiferana Clem.) outbreaks are one of the most significant disturbances of Picea

Journal of Quaternary Science, Volume 41, Issue 7, Page 1178-1199, October 2026.ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Budworm-linked warblers as early indicators of defoliation by spruce budworm: A field study
Ecological Indicators, 2021 Outbreaks of eastern spruce budworm (Choristoneura fumiferana; hereafter SBW) are a major natural disturbance in coniferous forests of eastern North America. These outbreaks provide a superabundant source of food for insectivorous birds.
