The Arctic Ocean is rapidly changing. Air temperature rising two to four times faster in the than global average, with dramatic consequences for ecosystems. Polar zooplankton species have cope those increasing temperatures, whilst simultaneously facing competition by boreal-Atlantic sister advected into via a stronger Atlantic inflow. To assess sensitivity of and respiration rates dominant ( Ca...

Potentilla L. (Rosaceae) species have been used in traditional medicine in Asia, Europe and Northern America. This study analyzed the biological activity of aqueous extracts of Potentilla species (Rosaceae): Dasiphora fruticosa (syn. P. fruticosa), P. norvegica, P. pensylvanica, P. thuringiaca, P. crantzii and P. nepalensis. The activities were tested using MTT, NR and DPPH assays on normal hum...

Rapid identification of Candida species has become more important because of an increase in infections caused by species other than Candida albicans, including species innately resistant to azole antifungal drugs. We previously developed a PCR assay with an enzyme immunoassay (EIA) format to detect amplicons from the five most common Candida species by using universal fungal primers and species...

Most fishes and crustaceans respond to light, and artificial light sources may therefore be an efficient stimulus to manipulate behaviours in aquatic animals. It has been hypothesised that the catch efficiency of pots could be increased if prey, for example krill, can be attracted into the pots providing a visual stimulus and a source of live bait. To find which light characteristics are most a...

Abstract Arctic zooplankton develop large energy reserves, as an adaptation to strong seasonality, making them valuable prey items. We quantified the content (kJ g −1 dry weight) of abundant krill (arcto-boreal , Thysanoessa inermis and boreal, Meganyctiphanes norvegica ) amphipods (Arctic, Themisto libellula sub-Arctic-boreal, abyssorum in Barents Sea late summer (August) early winter (Decembe...

159 forest relevés on sample plots (400 m2 each) at Smolenskoye Poozerye National Park were collected during the period from 2017 till 2022. Lichen diversity of was analyzed simultaneously. 25 lichen species preliminary list indicators biologically valuable landscapes in coniferous-broadleaved subzone European part Russia found plots. Two more (Pyrenula nitida and Toniniopsis separabilis) added...
