Wooded pastures combine trees and pastures in a land-use system resulting from traditional silvopastoral practices. With their sparse tree cover, wooded pastures represent an ecotone between open area pastures and forests with potentially high species diversity, although this is poorly tested for animal groups especially insects. In this study, we aimed to characterise and compare species communities in terms of species composition and diversity indices, biomass and ecological traits of ground beetles in wooded pastures, forests and non-wooded pastures.

Im Rahmen eines Forschungs- und Entwicklungsvorhabens zur Ausgestaltung von Durchlassbauwerken für Kleintiere, gefördert durch das Bundesamt für Naturschutz, wurde die Nutzung von Querungshilfen durch verschiedene Artengruppen untersucht, um Anforderungen an eine erfolgreiche Wiedervernetzung von Ökosystemen über Verkehrswege hinweg besser definieren zu können.

In natural populations, vital rates such as survival and reproduction are influenced by a complex interplay of abiotic conditions (e.g., environment), density dependence, and individual factors (e.g., phenotypic traits). Studies at the extremes of species distributions, particularly high elevations, offer unique insights due to the intensified effects of abiotic stressors, which can amplify both direct and indirect effects on vital rates.

Abstract: Addendum to the Hydrophiloidea species checklist of Switzerland: Helophorus nanus Sturm, 1836 (Coleoptera: Helophoridae). − Helophorus nanus Sturm, 1836 was not included on the 2023 checklist of the Hydrophiloidea of Switzerland. Although this species was mentioned for Switzerland in the past, historical literature citations were not supported by specimens in collections. In this note, we present proof of its presence in Switzerland based on specimens collected in 2023 in the canton of Schaffhausen.
