In the article was considered species composition of fish in the littoral and sublittoral zones of Yarnyshnaya and Zelenetskaya bays (Barents Sea) during summer and autumn 2019. At whole was discovered 15 species of fish and most abundent between them is young shorthorn sculpin Myoxocephalus scorpius. Also quantitative characteristics of the distribution for each fish species are represented. The dynamics of abundance and diversity of coastal fish communities were analyzed. Comparing of perennial data with 2019 indicates that at the present observed low abundance of young Gadidae, the presence of subdominant species, but high indicators of biodiversity in coastal communities.

The analysis of the influence of climatic factors on fluctuations in the flow of the Ob River is carried out. Based on the analysis of long-term series of annual and seasonal runoff of the Ob and differential integral curves, the phases of change in river flow ar e revealed. Spatial features of changes in precipitation and air temperature in different periods of water content have been studied. Mathematical and statistical processing of cartographic images made it possible to identify areas of the predominant influence of various climatic factors on the volume of river flow. The areas of the basin where climatic fluctuations had the greatest impact on the change in the Ob River flow in 1930–2017 have been identified. One of these areas is confined to the basin of the Tobol River, the second is adjacent to the Ob and Yenisei watershed. It is shown that the increase in winter water runoff is largely due to fluctuations in precipitation and air temperature. It is impossible to completely exclude the impact of permafrost degradation on the volume of Ob runoff, but it is obvious this factor is not significant.

The results of seasonal studies of the ichthyofauna carried out at the top of the estuary of the Tuloma River in April, June, September and October 2018–2020 are presented. The dominant species in the water area is the European flounder; its abundance in net catches increases from April to September. Distribution density in September 2020 varied from 13 to 1667 ind/ha, biomass – from 0.013 to 276.9 kg/ha. European flounder in the study area in the spring-summer period is represented mainly by juveniles from 15 to 18.5 cm long. In autumn, six- to seven-year-old individuals with a size group of 22–24 cm were recorded. The age of European flounder in the area did not exceed 8+ years. The sexual structure, stages of gonadal maturity and nutrition of the European flounder are also considered.

Phytoplankton organisms are the basis of the trophic chain and primary producers in the pelagial of the Barents Sea. The variation in phytoplankton biomass during the growing season is closely related to the change in chlorophyll a concentration. The data on the concentration of chlorophyll a in situ collected during the long-term (2006, 2007, 2010, 2013, 2015–2019) MMBI expedition research were compared with remote satellite sensing data. More than 200 in situ samples and satellite data were analyzed on the same dates in a 5x5 km square centered on the sampling point. It was revealed that permanent cloud cover over the Barents Sea interferes with the complete remote monitoring of this water area. The small number of coincidences of concentrations in situ with satellite data does not allow achieve global monitoring goals. Having analyzed the relationship of sea surface temperature as a key factor affecting the spatial and temporal distribution of chlorophyll a, a high degree of correlation (r = 0.89) between the parameters under consideration was determined, which indicates a sufficiently high reproducibility of the data of field measurements by satellite instruments.

A classification of habitats based on the topographic position of biotopes and plant communities, which diagnose them, is proposed. A map of undisturbed habitats of the watershed areas of the southern tundra of the Nenets Autonomous Okrug was compiled, which are subdivided into 5 categories at the second and 12 at the third level and correspond to 17 syntaxa.

The results of long-term studies of the ecological and physiological features of vascular plants in the Arctic tundra on the island of Spitsbergen are presented. Data on the content of plastid pigments for 98 vascular plants species from 20 families. The range of chlorophyll content is 0,4–2,6 mg / g of fresh weight. The relationship between the content of pigments and some indicators of functional activity of Arctic plants is analyzed. The content of flavonoids in the leaves of 63 species of vascular plants was studied. It is shown that 85 % of the studied species have high and medium values (4–11 %) of the flavonoid content. This is 2–3 times higher than in similar species of the Kola Subarctic. The composition of lipids in the leaves of the dominant and rare plant species of the Arctic tundra during the active vegetation period is analyzed. It was found that the dominance of saturated or unsaturated fatty acids in total lipids depends on the cold resistance of plant species and their representation in the ecotopes of the studied territory.

The present study provides new results of an inventory of cyanobacterial species from the North part of the Polar Urals Mountains. This territory is characterized as a unique geographical position in the transition between sub-Arctic and Low-Arctic zone and heterogeneous natural conditions. In 2019 expedition in a total of 52 localities were studied, 232 samples collected. The species identification was based on morphological features only. As a result, twenty-three species are reported for the Polar Urals flora for the first time. Feasibly, unexplored biodiversity of the terrestrial cyanobacteria of this territory is very high. This is due to both the presence of a large number of montane habitat types and the geological diversity of rock.
