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

open access: yesEcological 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 ...

Temperature elevation broadens the dietary niche of an insect herbivore

open access: yesEcological Entomology, EarlyView.
The realised dietary niche in Chrysomela lapponica was the narrowest at 10°C, whereas higher temperatures (15–25°C) broadened the dietary niche by increasing preference for and survival on suboptimal host plants. Elevated temperature broadened the realised dietary niche through both direct effects on beetles and indirect effects mediated by temperature‐

Kant's Solution to the Trilemma of Concept Formation

open access: yesEuropean 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.

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

Variation in forest area influences post‐fledging development and dispersal onset in the Eurasian Goshawk (Astur gentilis)

open access: yesIbis, EarlyView.
Natal dispersal is a key ecological process influencing gene flow, population connectivity and individual fitness. In altricial birds, the transition from fledging to natal dispersal is mediated by the post‐fledging dependence period, which is often difficult to observe in elusive, forest‐dwelling species.
