Wolbachia prevalence and diversity in selected riverine predatory beetles (Bembidiini and Paederini)

2018

Despite the many studies on Wolbachia in Coleoptera, data about the prevalence of this bacterium among ground and rove beetles are missing. This study describes Wolbachia distribution and diversity in predatory beetles co-habiting the same environment - submontane river channels. Three species of Paederini (Staphylinidae) and four Bembidiini (Carabidae) were collected from six river catchments of the Carpathians. Wolbachia was absent in three species: Paederidus rubrothoracicus (Goeze), Bembidion decorum (Zenker in Panzer), Bembidion modestum (F.) - but detected in four others. Paederus limnophilus Erichson and Paederidus ruficollis F. were infected at only some sites by different strains o…

Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards

2022

Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle the effects of habitat area (area of vegetated vineyards), habitat fragmentation (number of vegetated vineyard…
