Аннотация: Deep insight into types of vegetation variability provided by AVHRR space scanner images of vegetation index spatial distribution helps reveal impact of land surface changes on environment. The Institute of Computational Modeling SB RAS has developed nonparametric algorithms of automatic to classify and recognize patterns of these images which helped to reveal: (1) major variability types (generally connected); (2) areas belonging to small classes, which can be used to reveal deviations from 'normal' (e.g., forest fires, etc.); (3) deviation from a certain type of dynamics indicative of changes in condition of plants, which can be used to diagnose pathology at early stages; (4) impact of economical activities on vegetation in Norilsk area. The authors provide biological interpretation of the satellite data. Computer-animated dynamics and color maps are presented. Nonparametric algorithms of an automatic classification and pattern recognition were provided by the Institute of Computational Modeling SB RAS. (C) 2000 COSPAR. Published by Elsevier Science Ltd.

Fatty acid composition of fish species with different feeding habits from an Arctic Lake / M. I. Gladyshev [et al.] // Doklad. Biochem. Biophys. - 2017. - Vol. 474, Is. 1. - P220-223, DOI 10.1134/S1607672917030164 . - ISSN 1607-6729
Аннотация: We compared the composition and content of fatty acids (FAs) in fish with different feeding habits (sardine (least) cisco Coregonus sardinella, goggle-eyed charr (pucheglazka) form of Salvelinus alpinus complex, humpback whitefish Coregonus pidschian, broad whitefish Coregonus nasus, boganid charr Salvelinus boganidae, and northern pike Esox lucius from an Arctic Lake. Feeding habits of the studied fish (planktivore, benthivore, or piscivore) significantly affected the composition of biomarker fatty acids and the ratio of stable isotopes of carbon and nitrogen in their biomass. The hypothesis on a higher content of eicosapentaenoic and docosahexaenoic acids in the fish of higher trophic level (piscivores) when compared within the same taxonomic group (order Salmoniformes) was confirmed. © 2017, Pleiades Publishing, Ltd.

Senecella siberica -- marine glacial relict -- zooplankton -- Norilsk lakes -- central Siberia
Аннотация: The large, deep, freshwater Norilsk lakes (Lake Lama, Lake Sobachye, Lake Glubokoe and Lake Keta) are located beyond the Arctic Circle, at the northwestern edge of the Putorana Plateau. They underwent a Pleistocene boreal marine transgression. A relict of that transgression, Limnocalanus macrurus Sars 1863 (Copepoda, Calanoida), presently dominates the crustacean zooplankton of these lakes. Sympatric with the native relict species L. macrurus, Senecella siberica Vyshkvartzeva 1994, was found in our zooplankton samples taken from the deep parts of lakes Lama and Sobachye in the summer-autumn of 2014-2016. Sampling was performed using a Juday net hauled vertically from a depth of 15, 20(25/30) and/or 50 m to the surface. All Senecella specimens were older copepodites, mainly CIV stage in Lama and Sobachye lakes in August and CV in Sobachye Lake in September; their abundance was low (25-2000 ind. m(-2)). They inhabited the central deeper regions of the lakes, contributing up to 7-14% to the total wet biomass of net zooplankton in 0-20 and 0-50 m strata. Previous sporadic and rather superficial samplings in these lakes missed Senecella due to its deep locations, low abundance levels and the absence of both the oldest copepodites and adults in summer.

Аннотация: During the winter of 2018, total zooplankton samples were taken under ice with a plankton net in Lake Sobachye, one of the large Norilsk lakes, in the western (April 13, May 6) and middle (May 6) parts at 70, 80 and 100 m depths. The previous assumption that Senecella in the large Norilsk lakes is reproduced in winter and is a univoltine species with a long (one year) generation development time has been confirmed. The assignment of adult individuals to the species Senecella siberica Vyshkvartzeva 1994 has also been confirmed.

Hydrochemical Indicators of Water Quality in the Norilsk-Pyasino Lake-River System after a Diesel Fuel Spill at Norilsk Heat and Power Plant 3 in 2020 / D. M. Bezmaternykh, A. V. Puzanov, A. V.

hydrochemistry -- water quality -- Pyasino River -- Lake Pyasino -- Norilsk -- diesel fuel
Аннотация: The results of a hydrochemical analysis of the consequences of an accidental fuel release in the Norilsk-Pyasino water system are presented. The pollution of watercourses in the catchment of Lake Pyasino (a nameless (Nadezhdinsky) creek, the Daldykan River, and the Ambarnaya River) with oil products, phenols, easily oxidizable and hard to oxidize organic matter (COD, PO, and BOD5), suspended solids, inorganic salts, and heavy metals at concentrations exceeding the background levels and MPC for fishery water bodies, as well as a temperature rise in waters of the nameless creek near Norilsk Heat and Power Plant 3 (CHPP-3), have been revealed. The contamination of the surface water decreases downstream in ascending order: nameless creek-Daldykan River-Ambarnaya River. The occurrence of oil products, phenols, and organic substances in the surface waters 2 months after the fuel spill is obviously due to their diffusion from the river bottom sediments, which accumulated a considerable quantity of heavy fractions of diesel fuel after the accident. Increased concentrations of Ca, Cu, Zn, Mn, Co, and Ni in the waters of the studied tributaries of Lake Pyasino are not directly related to the accident; they result from the general technogenic pollution of the territory and the increased geochemical background for these elements. Water contamination with oil products and phenols in the studied areas of Lake Pyasino (its central and northern parts) and the Pyasino River has not been detected. However, Pb concentrations exceed the MPC and Cd is recorded in the water, which is probably due to pollutants that accumulated in previous years.

Аннотация: The bacterial composition of water and sediments in Lake Pyasino and adjacent rivers has been studied by high-throughput sequencing for the first time. No hydrocarbon-degrading bacteria are found in the river sections exposed to the diesel spillage in May 2020. The Daldykan and Ambarnaya rivers, located downstream of the spill site, are dominated by bacteria that oxidize sulfur and heavy metals. At the same time, these bacteria are not found in Lake Pyasino, which is dominated by small cyanobacteria. Thus, the composition of bacteria in the water and sediments of the Norilsk-Pyasino lake-river system corresponds to the technogenic impact to which it is exposed and also demonstrates the buffer properties of Lake Pyasino as water flows into the Kara Sea.

Аннотация: An assessment of the species composition, abundance, biomass, and pigment characteristics of phytoperiphyton and phytoplankton of Lake Pyasino, its tributaries (Bezymyannyi Stream, Daldykan, Ambarnaya, and Norilskaya rivers), and the head of the Pyasina River has been carried out after a manmade accident (a diesel-fuel spill near the city of Norilsk in May 2020). A significant decline in the biomass and changes in the species composition of phytoperiphyton after the water was contaminated by fuel is revealed only near the spillage site (in the Daldykan River and the Ambarnaya River downstream the mouth of the Daldykan). Downstream, in the Ambarnaya mouth zone, as a response to the release of a large amount of nutrients during the decomposition of fuel products and dead organisms, as well as the mechanical cleaning of the bank line, there has been a massive growth of diatom and green algae (Tabularia tabulata, Spirogyra sp.) in the water column and the appearance of indicators of organic pollution (Euglenophyceae and Cryptophyceae). No significant changes in the plankton of Lake Pyasino and the Pyasina River in comparison with the data obtained in the second half of the 20th century (i.e., long before the accident) are found. Species composition and quantitative features, as well as amount and ratio of pigments, characterized the phytoplankton and phytoperiphyton of Lake Pyasino and the Pyasina River as a normally functioning freshwater community of oligotrophic waters. All this indicates the absence of a negative impact of the accidental fuel spill on the ecosystem of Lake Pyasino and the Pyasina River.

Аннотация: At the beginning of August, 2 months after 20 000 t of diesel fuel spilled into the Bezymyanny Stream (which took it out to the Daldykan and Ambarnaya rivers), the large Norilsk expedition of the Siberian Branch, Russian Academy of Sciences, sampled net zooplankton at 13 stations located in both sections of these rivers and Lake Pyasino with the Pyasina River outflowing from it. A comparative analysis of the species composition, abundance, biomass, and saprobity index of zooplankton at these stations has been carried out. The productions of rotifer and crustacean zooplankton and potential production of planktivorous fish in Lake Pyasino have been calculated. Based on the state of zooplankton, a gradual improvement in water quality has been observed from river areas exposed to the oil products to the northern part of the lake and the River Pyasina outflow. The low abundance and biomass of zooplankton in the lake (43 800 +/- 17 550 ind./m(3), 112.8 +/- 26.2 mg/m(3), on average) due to the dominance of rotifers (Ploesoma truncatum (Levander), Bipalpus hudsoni (Imhof), and Conochilus unicornis Rousselet) resulted in low values of zooplankton production and the potential production of planktivorous fish (0.85 kg/ha per season).
