Management and tree dieback alter beetle assemblage structure and body size distribution in a temperate German forest

Ecological Entomology, EarlyView.
Forest management and climate‐induced tree dieback alter the structural characteristics of forests, which could subsequently lead to changes in the structure of beetle assemblages. Beetle assemblages in more open forests exhibited less even abundance distributions, with fewer, more dominant species (higher rates of decline (r), higher dominance (d ...

Rapid decrease of the Labrador Sea’s influence on black spruce ecosystems with distance inland

Communications Earth & Environment
In eastern Canada, Black spruce (Picea mariana Mill. B.S.P.) grows in a wide variety of climates, from maritime-oceanic conditions near the Labrador Sea, to more continental climates, inland.

Kant's Solution to the Trilemma of Concept Formation

European Journal of Philosophy, EarlyView.
Abstract According to a widespread assumption, Kant's logical account of concept formation starts with comparison, where the latter involves concepts. On this assumption, the formation of a concept presupposes other concepts, so that the argument is threatened either by circularity, regress, or break‐off.

Trapped between food, heat, and insects: Movement of moose (Alces alces) and exposure to flies in the boreal forest of Alaska

Ecology and Evolution
Moose (Alces alces) in the boreal forest habitats of Alaska are unlike other northern ungulates because they tolerate high densities of flies (Diptera) even though flies cause wounds and infections during the warm summer months.

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.

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 ...

Black carbon in Quebec boreal black spruce forests

, 2013
Wildfires affect boreal forest carbon stocks through consumption of the vegetation and forest floor, and production of black carbon (BC). This by-product of organic matter’s incomplete combustion is an important component of the global soil carbon pool.
