Agricultural intensification, particularly pesticide use, has reduced beneficial organisms and their functional diversity in agroecosystems. We studied the effects of pulsed exposure to two common insecticides, Mospilan 20 SP (neonicotinoid - active ingredient (a.i.) acetamiprid) and Sherpa 100 EC (pyrethroid - a.i. cypermethrin), on the non-target ground beetle Poecilus cupreus (Coleoptera: Carabidae) in a large-scale landsca...

Increasing atmospheric CO 2 levels change the elemental composition in plants, altering their nutritional quality and affecting consumers and ecosystems. Ecological stoichiometry provides a framework for investigating how CO 2 -driven nutrient dilution in pollen affects bees by linking changes in pollen chemical element proportions to the nutritional needs of bees. We investigated the consequences of five years of Free Air CO...

Bees provide important ecological services, and many species are threatened globally, yet our knowledge of wild bee ecology and evolution is limited. While evolving from carnivorous ancestors, bees had to develop strategies for coping with limitations imposed on them by a plant‐based diet, with nectar providing energy and essential amino acids and pollen as an extraordinary, protein‐ and lipid‐rich food nutritionally similar t...

In this study, the effects of zinc nanoparticles (ZnO-NPs) and ions (ZnCl 2 ) on the mortality, growth, maturation, and cellular respiration of the earthworm Eisenia andrei were assessed. Earthworms were individually exposed for 98 days, starting from the juvenile stage, to soils contaminated with either ZnO-NPs or ZnCl 2 (125, 250, 500 and 1000 mg Zn kg −1 dry weight (dw)). Exposure to the highest-concentration ionic treatmen...

In the study presented here, we tested, how large a fraction of lysogenic culture was undergoing filamentation, which could indicate triggering of the SOS response or SOS-independent prophage induction that is also known to cause cell filamentation. Here, antibiotic stress was triggered by adding mitomycin C and oxidative stress was induced by hydrogen peroxide. Observation of bacterial cells under an optical microscope reveal...

A statistical model is derived relating the diurnal variation of sea surface temperature (SST) to the net surface heat flux and surface wind speed from a numerical weather prediction (NWP) model. The model is derived using fluxes and winds from the European Centre for Medium-Range Weather Forecasting (ECMWF) NWP model and SSTs from the Spinning Enhanced Visible and Infrared Imager (SEVIRI). In the model, diurnal warming has a...
