Abstract Freshwater mussels are ecosystem engineers and keystone species in aquatic environments. Unfortunately, due to dramatic declines this fauna is among the most threatened globally. Here, we clarify taxonomy biogeography of Russian Unionidae based on comprehensive multi-locus dataset sampled date. We revise distribution assess conservation status for each species. This comprises 16 native from 11 genera 4 tribes: Anodonta , Pseudanodonta (Anodontini); Amuranodonta Beringiana Buldowskia...
Birds, fish, and marine mammals consumed by indigenous people are included in Arctic biomonitoring. However, there still many gaps the data on microbiota associated with these animals. In current study, we used high-throughput 16S rRNA gene sequencing to explore bacterial diversity composition intestines of willow ptarmigans, greater white-fronted geese, taiga bean which widely Arctic. For first time, meta-taxonomic have been obtained lungs wild resident migratory birds Russian North. The...
Kraft pulp enzymatic hydrolysis is a promising method of woody biomass bioconversion. The influence composition and structure kraft fibers on their efficiency was evaluated while using four substrates, unbleached hardwood (UHP), softwood (USP), bleached (BHP), (BSP). Hydrolysis carried out with Penicillium verruculosum enzyme complex at dosage 10 filter paper units (FPU)/g pulp. changes in fiber morphology were visualized optical electron microscopy. Fiber cutting swelling quick xylan...
Permafrost peatlands, containing a sizable amount of soil organic carbon (OC), play pivotal role in (peat) OC transformation into soluble and volatile forms greatly contribute to overall natural CO2 CH4 emissions the atmosphere under ongoing permafrost thaw degradation. Peat microorganisms are largely responsible for processing this OC, yet coupled studies chemical bacterial parameters peatlands rather limited geographically biased. Towards testing possible impact peat pore water composition...
Exposure of Arctic residents to environmental pollutants is an emerging public health problem receiving little global attention. The objective this study was assess whole blood concentrations nine selected essential (Co, Cu, Mn, Se, Zn) and non-essential (As, Cd, Hg, Pb) elements among Nenets non-Nenets adult the Autonomous Okrug (NAO) living in seven coastal inland settlements. Urine collected two settlements for assessment iodine status. Altogether 297 68 urine samples were analysed by...
The global development of the bioeconomy is impossible without technologies for comprehensive processing plant renewable resources. use proven pretreatment raises possibility industrial implementation enzymatic conversion polysaccharides from lignocellulose considering process’s complexity. For instance, a well-tuned kraft pulping produces substrate easily degraded by cellulases and hemicelulases. Enzymatic hydrolysis bleached hardwood pulp was carried out using an enzyme complex...
Sulfite and kraft pulping are two principal methods of industrial delignification wood. In recent decades, those have been considered as possibilities to pretreat recalcitrant wood lignocellulosics for the enzymatic hydrolysis polysaccharides subsequent fermentation obtained sugars valuable bioproducts. Current work compares chemistry technological features different cooking processes in preparation polysaccharide substrates deep saccharification with P. verruculosum glycosyl hydrolases....
Currently, monitoring of persistent organic pollutant (POP) content in various biological and environmental matrixes the Arctic is an urgent task. The present study focused on determination POPs such as: PCB#28, PCB#52, PCB#101, PCB#105, PCB#118, PCB#123, PCB#153, PCB#128, p,p’-DDE, o,p’-DDE, p,p’-DDD, o,p’-DDD, hexachlorobenzene (HCB), cis-nonachlor, trans-nonachlor, cis-chlordane, trans-chlordane, mirex, 1,2,3,5-tetrachlorobenzene 1,2,4,5-tetrachlorobenzene fish consumed by indigenous...
Persistent organic pollutants (POPs) are heterogeneous carbon-based compounds that can seriously affect human health. The aim of this study was to measure serum concentrations POPs in women residing the Euro-Arctic Region Russia. A total 204 from seven rural settlements Nenets Autonomous Okrug (NAO) took part study. We measured 11 polychlorinated biphenyls (PCBs) and 17 organochlorine pesticides (OCPs) across sites among non-Nenets residents. Measurement performed using an Agilent 7890A gas...
Abstract Fish muscle may constitute one of the main sources iodine (I) for indigenous peoples Russian Arctic, although limited information is available about its content in commonly consumed fish species. In current study, bromine (Br), I, essential elements (copper, selenium and zinc) other non-essential — specifically mercury, arsenic (As), cadmium, lead nickel have been quantified 10 species by people living Nenets Chukotka Regions. was analysed ICP-MS after nitric acid or...
We studied freshwater molluscan communities and the reproduction of pea clam Pisidium casertanum in three types Arctic lakes. The lakes differed limnological features, both within across lake type; although composition assemblages were similar, abundances varied considerably. Whereas abundance P. was not related to water macroion composition, shell length negatively concentrations SO42−, Cl−, Mg2+, Na+ Ca2+. average number embryos positively correlated only with Mg2+ content. Patterns...
Introduction: Arctic ecosystems are the most important object of microbiological surveillance that helps monitor a rapidly changing natural environment affected by climate change and industrial development northern territories. Objective: To assess epidemic potential opportunistic bacteria associated with animals from islands Barents Kara Seas. Materials methods: We have studied four strains gram-negative (Serratia fonticola, Aeromonas salmonicida, Yersinia kristensenii, rochesterensis)...
Intestinal bacterial community in rainbow trout (Oncorhynchus mykiss) is increasingly recognized as important for aquaculture and fish health. This review summarizes the current knowledge on how various feed components, including animal- plant-derived ingredients, well other additives, influence gut microbiota of trout. Studies using 16S rRNA gene profiling metagenomics demonstrate dietary changes affect composition, diversity, functionality communities. The findings suggest that there no...
The raw concentration data for the research article entitled "Essential and non-essential trace elements in fish consumed by indigenous peoples of European Russian Arctic" (Sobolev et al., 2019) [1] are herein presented. Fifteen species were collected Nenets Autonomous Arkhangelsk Regions Federation analysed 9 (As, Cd, Co, Cu, Hg, Ni, Pb, Se Zn). sampling sites located parts Arctic sub-Arctic territories. Within these territories, commonly catch consume local fish. Based on questionnaire...
The overwhelming majority of Arctic biomonitoring studies in humans include either pregnant or non-pregnant women reproductive age while little attention is paid to toxic compounds concentrations men. This study contributes with information the present amounts persistent organic pollutants (POPs) men living Russia. We studied serum 11 polychlorinated biphenyl (PCB) congeners and 17 organochlorine pesticides (OCPs) some their metabolites samples collected from 92 adult (mean 43 years) seven...
