Population dynamics and reproductive success of Short‐eared Owls in relation to widely fluctuating food abundance and farmland habitat degradation

Ibis, EarlyView.
Populations of the Short‐eared Owl Asio flammeus have declined across Europe and North America, probably in response to habitat degradation driven by agricultural intensification. However, long‐term evidence linking farmland habitat change to variation in breeding density and reproductive success remains limited.

Population genetic analysis of the endangered Mottled Duskywing butterfly (Erynnis martialis) informs species reintroduction

Insect Conservation and Diversity, EarlyView.
Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...

Small birches matter: Beetle diversity on burned birch and pine in boreal forests

Insect Conservation and Diversity, EarlyView.
Burned birch hosted higher beetle richness than burned pine. Higher beetle richness on birch was associated with its greater post‐fire mortality, with charred, dead birches attracting more specialized beetles. Retaining burned birch alongside pine can enhance saproxylic and pyrophilous beetle diversity after prescribed burning.

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

Insect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

Lignan‐rich Norway spruce (Picea abies) resin extract exhibits anti‐inflammatory, skin‐regenerative and anti‐acne effects: In vitro, in silico, biocompatibility and exploratory clinical findings

International Journal of Cosmetic Science, EarlyView.
GA text A 30% Picea abies resin extract cream combined antimicrobial, anti‐inflammatory and early pro‐repair activities relevant to acne‐prone skin. The formulation showed strong activity against Cutibacterium acnes, reduced inflammatory cytokines and demonstrated promising tolerability and efficacy in an exploratory in‐use study.
