Glyphosate is a widely used agrochemical. Nevertheless, only a few studies have investigated its effect on bees, specifically its influence on their foraging activity. This article provides a summary of the prominent research results on this issue, published in journals in the field of experimental biology. The effect of commonly used concentrations of glyphosate on honey bee navigation has been evaluated in several studies, as well as concentrations that are reportedly sublethal. Exposure to this herbicide increases the flight time back to the hive and affects the flight trajectories of these bees. These results imply that glyphosate at certain concentrations...

Previous studies of the effects of elevated CO2 (eCO2) concentrations and heavy metal stress conditions on plant growth and physiology have mostly focused on crops rather than vegetables. In this study, we investigated the effects of Cd stress on the growth and antioxidant system of pak choi (Brassica rapa L.), water spinach (Ipomoea aquatica Forssk.), cherry radish (Raphanus raphanistrum subsp. sativus (L.) Domin) and pepper (Capsicum annuum L.) growing in pots under ambient CO2 (aCO2) or eCO2 conditions. In general, Cd stress reduced plant biomass and SPAD values...

This study identified three soil bacteria (NRRU-BW3, NRRU-BW3, and NRRU-TV11) that degrade chlorpyrifos, produce indole-3-acetic acid, and exopolysaccharides under pesticide stress. The results revealed that soil bacteria were identified as Priestia megaterium NRRU-BW3, Bacillus siamensis NRRU-BW9, and Bacillus amyloliquefaciens NRRU-TV11. These strains showed the ability to produce indole-3-acetic acid (IAA) and exopolysaccharides (EPS) in chlorpyrifos. Moreover, these bacteria can degrade chlorpyrifos (CP) in an aqueous medium, and a 33–52% degradation rate was observed after 14 days of incubation. Inoculation with the...

This study aimed to determine the effect of tea planting age on stoichiometric ratios of microbial biomass carbon (MBC), nitrogen (MBN), and phosphorus (MBP) and soil microbial quotient (SMQ, expressed as qMBC, qMBN, and qMBP, respectively). A chronological sequence of tea plantations (3, 8, 17, 25, and 34 years) was selected in a small watershed in the Three Gorges Reservoir Area, and a slope farmland was selected as control. The results showed that with the increase of tea plantation age, soil and microbial biomass C, N, P contents, soil C : N and C : P elevated significantly, while soil N : P overall declined;...

Water and nutrient use efficiencies are important adaptive features of plants in arid and semi-arid environments. In this study, water, nitrogen (N), and phosphorus (P) use efficiencies of Stipa purpurea Griesb., an endemic and dominant grass species, were investigated in the alpine steppe along precipitation gradients on the Tibetan Plateau. The leaf N content of S. purpurea increased along the precipitation gradient, but leaf P decreased, whereas carbon (C) remained unchanged. Leaf δ13C (water use efficiency, WUE) and C : N ratio (N use efficiency, NUE) decreased with increasing precipitation. But leaf C : P...

Surface runoff and soil losses in the case of potato cultivation using de-stoning technology on gentle slopes (Haplic Cambisol) were studied in 2020–2022. Different ridges shapes were compared: control (smooth shaped ridges), pits, pits plus loosening, pits plus loosening plus cover crop (Triticum aestivum L.) sowing in trail furrows. Runoff and soil losses were studied approximately 1 and 2 months after planting potatoes. The obtained results showed the highest reduction of surface runoff and soil losses in the treatment with cover crop sowing. In this variant, soil losses were reduced by 65–81% (1 month after planting) and 54–85%...
