Continent‐wide population genomic structure and phylogeography of North America’s most destructive conifer defoliator, the spruce budworm (Choristoneura fumiferana)

open access: yesEcology and Evolution, 2020
The spruce budworm, Choristoneura fumiferana, is presumed to be panmictic across vast regions of North America. We examined the extent of panmixia by genotyping 3,650 single nucleotide polymorphism (SNP) loci in 1975 individuals from 128 collections ...

Fungal Interactions and Host Tree Preferences in the Spruce Bark Beetle Ips typographus

open access: yesFrontiers in Microbiology, 2021
The spruce bark beetle Ips typographus is the most damaging pest in European spruce forests and has caused great ecological and economic disturbances in recent years. Although native to Eurasia, I.

Peer Pressure: Do the Fitness Benefits of Animal Behavioral Traits Vary With Conspecific Density?

open access: yesEthology, EarlyView.
We show that the activity of juvenile North American red squirrels influenced their survival in a density‐dependent manner: more active individuals had higher survival under high conspecific density, whereas less active juveniles had higher survival under low densities. Juveniles who were both more active and aggressive were more likely to survive. Our

In vivo function of Pgβglu-1 in the release of acetophenones in white spruce [PDF]

open access: yesPeerJ, 2017
Eastern spruce budworm (Choristoneura fumiferiana Clemens) (ESBW) is a major forest pest which feeds on young shoots of white spruce (Picea glauca) and can cause landscape level economic and ecological losses.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

open access: yesNew Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Soil carbon storage and stability controlled by site properties more than forest management in a humid boreal forest

open access: yesSoil 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 ...

Comparative Genomics Analysis of Repetitive Elements in Ten Gymnosperm Species: “Dark Repeatome” and Its Abundance in Conifer and Gnetum Species

open access: yesLife, 2021
Repetitive elements (RE) and transposons (TE) can comprise up to 80% of some plant genomes and may be essential for regulating their evolution and adaptation.

The Genome and Population Structure of the Spruce Beetle, Dendroctonus rufipennis (Kirby, 1837), a Transcontinental Pest of North American Spruce

open access: yesMolecular Ecology Resources, Volume 26, Issue 8, November 2026.
ABSTRACT The spruce bark beetle Dendroctonus rufipennis (Family: Curculionidae; Subfamily Scolytinae) is a major forest insect pest throughout the transcontinental range of spruce species (Picea spp.) in North America. Here, we present an annotated, near chromosome‐level, genome assembly of 271 Mb, with 86% of the assembly contained in 16 ...

Variation among populations of Quercus macrocarpa in a reciprocal transplant experiment across a latitudinal gradient

open access: yesEcology, Volume 107, Issue 10, October 2026.
Abstract Ongoing climate change will negatively impact tree populations unless they are able to acclimate to the changes in their local environment. Effective planning for climate adaptation management requires an understanding of the current state of local adaptation and physiological performance to assess whether populations are at risk of local ...
