Аннотация: The source of radioactive contamination of the Yenisei River floodplain, including contamination with transuranic elements, is the Mining-and-Chemical Combine of the Russian Ministry of Atomic Energy, which has for many years been producing weapons-grade plutonium. Transuranic elements have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. This work is an investigation of accumulation and release of 241Am by a submerged macrophyte of the Yenisei River (Elodea canadensis) in laboratory experiments. In 2000-2003, laboratory experiments were carried out with biomass of E. canadensis Mich. and filtered river water. The samples were collected from the Yenisei River upstream of the discharge of the Combine's radioactive effluent. The experiments showed that 241Am is accumulated by Elodea biomass: the activity concentration of 241Am can reach 3280 В± 240 Bq/g, with the concentration factor for 241Am 16 600 В± 2200 l/kg. Results of chemical fractionation have proved that in the course of 241Am accumulation by Elodea biomass, 241Am tightly bound to biomass increases from 11% to 27% of the total 241Am in the biomass. Release of 241Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial 241Am activity and the rate of 241Am release into the water environment reached 23 Bq/day.

Аннотация: The study addresses 242Pu accumulation by Elodea canadensis, one of the abundant species of submerged plants in the Yenisei River. 242Pu in water samples of the "Elodea - Yenisei River water" model system and in the biomass fractions was determined ?-spectrometrically, following radiochemical recovery of 242Pu using 236Pu - a chemical yield tracer. The experiments on accumulation of 242Pu by Elodea biomass showed that the activity concentration of 242Pu can reach 21 В± 2 Bq/g dry wt, with the concentration factor for 242Pu 13100 В± 2100 L/kg dry wt. Results of chemical fractionation proved that during the first few hours of the experiment 242Pu contained in Elodea was mainly concentrated in the exchangeable and the adsorbed fractions of biomass (about 100%). As Elodea biomass accumulated 242Pu, the absolute amount of 242Pu in the exchangeable and the adsorbed fractions remained almost unchanged, although the portion of 242Pu tightly bound to biomass increased. At the end of the experiment, on day 7, 242Pu tightly bound to biomass (fractions of organics and mineral residue) constituted 43-63% (in different experiments) of the total 242Pu in the biomass.

Аннотация: The source of radioactive contamination of the Yenisei River floodplain, including contamination with actinides, is the Mining-and-Chemical combine (MCC), which has for many years been producing weapons-grade plutonium. Actinides have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. The aim of our investigation was to assess the levels of actinides and other radionuclides in sediments and aquatic plants both near the MCC and at a considerable distance from it, down the Yenisei River. Investigations of the Yenisei River sediment samples revealed high activity concentrations of actinides (Pu isotopes and 241Am), which were 100 times higher than their global fallout levels. Sequential extraction of radionuclides from samples of sediments collected near the MCC showed that the amounts of extracted 241Am were the largest (up to 98% of initial activity). It was found that aquatic plants of the Yenisei River collected both near the MCC discharge site and at a distance up to 200 km downstream contained several actinide isotopes. The aquatic moss, Fontinalis antipyretica, was found to contain higher levels of radionuclides than Potamogeton lucens. Leaves of P. lucens contained higher levels of radionuclides, including 239Np, than stems. Sequential extraction of radionuclides from samples of aquatic plants showed that 239Np levels in exchangeable and adsorption fractions of P. lucens biomass were higher than in the respective fractions of F. antipyretica biomass.

Аннотация: Conservation and sustainable management of aquatic ecosystems is a priority in environmental programs worldwide. However, these aims are highly dependent on the efficiency, accuracy and cost of existent methods for the detection of keystone species and monitoring of biological communities. Rapid advances in eDNA, barcoding and metabarcoding promoted by high-throughput sequencing technologies are generating millions of sequences in a fast way, with a promising cost reduction, and overcoming some difficulties of the traditional taxonomic approaches. This paper provides an updated broad perspective of the current developments in this dynamic field presented in the special session (SS) "The use of molecular tools in ecological and biodiversity assessment of aquatic ecosystems" of the XIX Congress of the Iberian Association of Limnology (AIL2018), held in Coimbra, Portugal. Developments presented are mainly focused on the Iberian Peninsula (Portugal and Spain, including Atlantic Macaronesian islands) but include studies in France, Germany, Finland, Russia (Siberia) and South America. The networks within which these researchers are involved are yet even broader, profiting from existing molecular facilities, and traditional taxonomic expertise, which can be viewed as a characteristic of this new research area. It was evident in the SS that the use of molecular tools is widespread, being used to study a diversity of aquatic systems, from rivers' headwaters to estuaries and coastal lagoons, and volcanic, mountain and frozen lakes to hot springs. The organisms targeted are likewise varied and include fish, macroinvertebrates, meiofauna, microalgae such as diatoms and dinoflagellates, other protists, fungi, and bacteria (cyanobacteria and other). Some studies address the whole biodiversity (i.e., all species present independently of the taxonomic group) from environmental samples of water, biofilms and preservative solution from field samples (e.g., ethanol from macroinvertebrate samples). Great advances were acknowledged in the special session, namely in the use of metabarcoding for detecting hidden biodiversity, juvenile stages, low-abundance species, non-indigenous species and toxicity potential, and ultimately for ecological monitoring of diatoms and invertebrates. Yet, several drawbacks were highlighted and need further work, which include: taxonomic gaps in the reference databases (including gaps at species level and on intraspecific variability) or absence of public databases (e.g. for meiofauna), still high sequencing costs, the need of a substantial bioinformatics effort, difficulties in establishing the amount of environmental sample necessary for a good DNA extraction and the need for testing different genetic markers to obtain accurate results.

Аннотация: The bacterial bioluminescence has high sensitivity to the action of various inhibitors of biological activity. The lyophilized luminous bacteria Photobacterium phosphoreum (Microbiosensor B17 677F) and luminous strain Escherichia coli (Microbiosensor EC) from the Culture Collection IBSO were used to create bioluminescent biotests. They have been applied in ecological monitoring to determine the overall toxicity of the Yenisei and Angara Rivers and some water sources of Altai Territory. As a rule the heaviest pollution of water in studied rivers was registered near cities and settlements. The luminous bacteria biotests are simple and convenient in work, standardized and quantitative, have rapid response to actions of different substances and high sensitivity to environmental pollutants. It takes less than 30 min to do the biotest (the other biotests take 48-96 h). Copyright В© 1999 John Wiley & Sons, Ltd.

Аннотация: The Yenisei River, one of the largest rivers in the world, is contaminated with artificial radionuclides released by one of the Russian nuclear plants, which produces weapons-grade plutonium and has been in operation for many years. The aim of the study that was conducted between 1997 and 2002 was to investigate accumulation of artificial radionuclides by aquatic plants of the Yenisei River. The aquatic plants sampled were: Potamogeton lucens (shining weed) and Fontinalis antipyretica (water moss). The ?-spectrometric analysis of the samples of aquatic plants for artificial radionuclides has revealed a wide spectrum of long-lived and short-lived radionuclides. Artificial radionuclides such as 51Cr, 54Mn, 58Co, 60Co, 65Zn, 137Cs, and 152Eu were found in aquatic plants collected both near the plutonium complex and 194 km downstream in the river. The radiochemical analysis of aquatic plants revealed strontium and isotopes of plutonium. Fontinalis antipyretica had very high concentration factors of the principal radionuclides: 14220, 3110 and 500 of 51Cr, 46Sc and 239Np, respectively.

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: We studied species composition, density, biomass and production of larvae of the family Ceratopogonidae in two saline rivers (Volgograd region, Russia). Ceratopoponids make up an important part of macroinvertebrate community in these rivers. Average monthly production (dry weight) of ceratopogonid larvae in the rivers was 3.5-4.8 g m -2 month -1 in May and ?0.9 g m -2 month -1 in August. For the first time, feeding spectra of ceratopogonid larvae, Palpomyia schmidti Goetghebuer, 1934, was studied using fatty acid analyses. The larvae of P. schmidti appeared to selectively consume diatoms and other algae and to avoid bacteria and decomposed dead organic matter (detritus) of low nutritive quality. © CSIRO.

Аннотация: The Yenisei River is contaminated by artificial radionuclides released by one of the Russian facilities producing weapons-grade plutonium (the Mining-and-Chemical Combine, MCC), which has been in operation for 60 years. The paper presents results of long-term monitoring of radionuclide concentrations in six aquatic plant species collected from the 1400 km Yenisei River stretch downstream of the city of Krasnoyarsk. Before the last MCC reactor was shut down (in 2010), up to 30 artificial radionuclides were detected in the plant biomass, and 2 and 5 years after the reactor shutdown, 11 and 3–5 radionuclides, respectively, were detected. The highest concentrations of radionuclides were recorded in Fontinalis antipyretica. The aquatic plant Elodea canadensis, which commonly occurs in the Yenisei River, was used in the cytogenetic study. High frequencies of chromosomal aberrations (up to 33%) were revealed in cells of Elodea canadensis roots from the Yenisei region affected by the MCC radioactive discharge, at dose rates of 45–72 ?Gy/d, while in the cells of the plant roots from the reference areas, the frequency of chromosomal aberrations was 5–7%, at dose rates below 2 ?Gy/d. The higher frequencies of chromosomal aberrations in Elodea canadensis collected from the parts of the River with increased concentrations of artificial radionuclides are associated with the radiation factor. The aquatic plant Elodea canadensis can be recommended as a bio-indicator for radioactively contaminated aquatic ecosystems. © 2019 Elsevier Ltd

Аннотация: Waters of the Yenisei River, certain rivers and lakes of the Altai Territory, and effluents of some industrial factories in Krasnoyarsk were studied by luminous bacteria biotest Microbiosensor B17 677F. The lyophilized luminous bacteria Photobacterium phosphoreum from the IBSO collection were used to design this biotest. The bioluminescent test is based on bioluminescence quenching resulting from the action of water samples on luminous bacteria. The test results indicated locations and zones of impaired water quality. The heaviest pollution of water in the Yenisei River was recorded in the zones 0-116 km downstream from Krasnoyarsk (Krasnoyarsk and satellite towns). The effluents of most factories were found to be toxic. Underground and surface waters of some areas of the Altai Territory had different toxicity levels; there were deviations from the norm in most water samples taken from the different lakes and rivers. The data from this study show that the luminous bacteria biotest is simple and convenient, and that the results obtained are within acceptable levels of accuracy for the evaluation of the toxicity of effluent and river water. It takes no more than 30 min to do the biotest. It can be used in ecological monitoring like the Microtox toxicity test. В© 1998 John Wiley & Sons, Inc.

Аннотация: The Yenisei River is contaminated with artificial radionuclides released by one of the Russian nuclear plants. The aquatic plants growing in the radioactively contaminated parts of the river contain artificial radionuclides. The aim of the study was to investigate accumulation of artificial radionuclides and stable elements by submerged plants of the Yenisei River and estimate the strength of their binding to plant biomass by using a new sequential extraction scheme. The aquatic plants sampled were: Potamogeton lucens, Fontinalis antipyretica, and Batrachium kauffmanii. Gamma-spectrometric analysis of the samples of aquatic plants has revealed more than 20 radionuclides. We also investigated the chemical fractionation of radionuclides and stable elements in the biomass and rated radionuclides and stable elements based on their distribution in biomass. The greatest number of radionuclides strongly bound to biomass cell structures was found for Potamogeton lucens and the smallest for Batrachium kauffmanii. For Fontinalis antipyretica, the number of distribution patterns that were similar for both radioactive isotopes and their stable counterparts was greater than for the other studied species. The transuranic elements 239Np and 241Am were found in the intracellular fraction of the biomass, and this suggested their active accumulation by the plants. В© 2011 American Chemical Society.

Аннотация: The trophic position of fish is one of the most important factors controlling the accumulation of potentially toxic elements and compounds in fish tissues, primarily via the spectrum of fish nutrition. In this study, the content of potentially toxic transition metals (Cu, Zn, Mn, Pb, and Cd) and radiocesium (Cs-137) in the edible tissues (muscles and liver) of two representatives of the fish-eating ichthyofauna of the Yenisei River, northern pike (Esox lucius) and burbot (Lota lota), have been comparatively studied relatively to the size of the fish. A significant decrease in the content of radiocesium and zinc in the muscles of pike and zinc in the liver of pike with an increase in body size has been recorded in juvenile pikes with a body weight (W) of less than 0.35 kg. For larger sexually mature pikes, no significant size dependences of the accumulation of metals in tissues are found. A positive correlation is found between the content of Cs-137, Cu, Zn, and Mn in muscles and the size of burbot in the W range from 0.42 to 1.62 kg. The tissues of burbots and pikes of the same size significantly (p < 0.05) differ in the concentration of metals in their tissues: concentrations of Zn and Mn are 1.6-2.2 times higher in the muscle of burbot; the concentration of Pb is 1.8 times higher in muscle of pike; Cu is twice as high in the liver of burbot; and Zn and Mn are 4.7 and 1.6 times higher in the liver of pike, respectively. These differences may be due to the different food spectra of pike and burbot. Concentrations of Cu, Zn, and Mn in the liver of pike are 3-7 times higher than in muscle; the concentration of Cu in the liver of burbot is 5 times higher than in muscle. Pb and Cd tend to be higher in liver than muscle for both fish species. Despite the revealed size dependences, the concentrations of potentially toxic metals and radiocesium in the muscles and liver of fish are below the permissible concentrations for food. These results can be used to assess environmental risks for the population consuming fish, as well as to plan for the long-term environmental monitoring of rivers using representatives of piscivorous fish.

Аннотация: Abstract: The contents of isotopes of plutonium (238Pu and 239, 240Pu) and 137Cs in samples of bottom sediments and hydrobionts (water moss, amphipods, and caddisfly larvae with casings) taken in the Yenisei River in the vicinity of the radioactive discharge from the Mining and Chemical Combine in 2012 and 2018 were comparatively estimated. It is shown that the content and ratios between the specific activities of plutonium isotopes (238/239 and 240) in samples of BSs and hydrobionts increased after the recommencing of plutonium discharges into the Yenisei due to the beginning of MOX fuel production. The background content and the ratio between plutonium isotopes in BSs of the Yenisei were estimated for the first time. Hydrobionts and BSs were ranged differently according to the content of plutonium and 137Cs: we recorded the highest content of 137Cs in BSs and that of plutonium in water moss. The plutonium content in hydrobionts of the Yenisei River varies considerably, which permits specification of representatives of biota (water moss and caddisfly larvae with casings) that, along with BSs, can be used as effective indicators of ecosystem pollution with plutonium. © 2020, Pleiades Publishing, Ltd.

Аннотация: Seasonal dynamics of contents of essential polyunsaturated fatty acids (PUFA) in dominant groups of benthic invertebrates: gammarids (Gammaridae, Amphipoda), oligochaetes (Oligochaeta), chironomid larvae (Chironomidae, Diptera) and caddisfly larvae (Trichoptera), and dominant benthivorous fish, Siberian grayling Thymallus arcticus, have been studied in ecosystem of the large Siberian river. During the year of the study most benthic invertebrate taxa showed significant variations in the contents of both C-18 and long chain C-20-22 PUFAs. In contrast, the fish, which consumed the zoobenthos, had no significant seasonal variations in long chain PUFAs' contents. Thereby, the fish, as organisms of relatively higher evolution level than invertebrates, was supposed to have more strict metabolic control of long chain PUFAs' contents. Evidence was obtained that the studied fish species, grayling, may be capable to convert dietary EPA into DHA. В© 2006 Elsevier Inc. All rights reserved.

Аннотация: An integrated study of the middle and lower Yenisei River was performed in the summer of 2012. It involved monitoring the key elements and ecological processes associated with the carbon cycle of the river ecosystem (the study area is more than 1800 km long). Measurements of the production and destruction processes have shown the failure of the "neutral pipe" hypothesis claiming that any river is a simple drain of carbon from terrestrial ecosystems to the ocean. The Yenisei River is not a purely heterotrophic ecosystem. It also has autotrophic areas, where the primary production of planktonic photosynthesis is higher than respiration (above the Angara River and near the Bolshaya and Malaya Heta rivers). According to the data, the respiration rate of the plankton community in the river depends mostly on the water temperature and the content of inorganic phosphorous that can restrict the amount of organic matter consumed by bacterioplankton.

Аннотация: Contents of highly unsaturated long-chain fatty acids of omega-3 family (HUFA); eicosapentaenoic acid (EPA; 20:5n-3); and docosahexaenoic acid (DHA; 22:6n-3) are the principal indicators of the nutritive quality of fish for humans. Effects of environmental factors, first of all water temperature, on EPA and DHA contents in fish tissue are not currently completely understood. To reveal the putative effect of water temperature, fatty acid composition and contents were studied for 6 fish species, inhabiting the cold waters of the Yenisei River (Siberia, Russia) downstream of a dam (hypolimnetic release from reservoir) and its adjacent warm water tributaries (the Mana River and the Kacha River). It was hypothesized that (a) fish species from the cold river would have higher HUFA contents than fish from the warm rivers and (b) temperature would be negatively correlated with HUFA content in fish species. Using gas chromatography-mass spectrometry, distinct species-specific fatty acid profiles were observed, whereas contents of the essential fatty acids, EPA and DHA, in fish species from the cold Yenisei River were in general similar to that from warm tributaries. Thus, in contrast to the first hypothesis, phylogenetic factors overweighed the effect of water temperature and food (benthic invertebrate) composition, on fatty acid composition and HUFA content in fish. For the second hypothesis, for the 2 species inhabiting both cold and warm rivers, only one had higher EPA and DHA content at lower temperatures. Consequently, the response of EPA and DHA content in fish tissue to temperature variations may be species-specific.

Аннотация: Globally, lake surface water temperatures have warmed rapidly relative to air temperatures, but changes in deepwater temperatures and vertical thermal structure are still largely unknown. We have compiled the most comprehensive data set to date of long-term (1970-2009) summertime vertical temperature profiles in lakes across the world to examine trends and drivers of whole-lake vertical thermal structure. We found significant increases in surface water temperatures across lakes at an average rate of+0.37 degrees C decade(-1), comparable to changes reported previously for other lakes, and similarly consistent trends of increasing water column stability (+0.08 kg m(-3) decade(-1)). In contrast, however, deepwater temperature trends showed little change on average (+0.06 degrees C decade(-1)), but had high variability across lakes, with trends in individual lakes ranging from -0.68 degrees C decade(-1) to+0.65 degrees C decade(-1). The variability in deepwater temperature trends was not explained by trends in either surface water temperatures or thermal stability within lakes, and only 8.4% was explained by lake thermal region or local lake characteristics in a random forest analysis. These findings suggest that external drivers beyond our tested lake characteristics are important in explaining long-term trends in thermal structure, such as local to regional climate patterns or additional external anthropogenic influences.

    Deeper waters are changing less consistently than surface waters in a global analysis of 102 lakes / R. M. Pilla, C. E. Williamson, B. V. Adamovich [et al.] // Sci. Rep. - 2020. - Vol. 10, Is. 1. - Ст. 20514, DOI 10.1038/s41598-020-76873-x . - ISSN 2045-2322
Аннотация: Globally, lake surface water temperatures have warmed rapidly relative to air temperatures, but changes in deepwater temperatures and vertical thermal structure are still largely unknown. We have compiled the most comprehensive data set to date of long-term (1970–2009) summertime vertical temperature profiles in lakes across the world to examine trends and drivers of whole-lake vertical thermal structure. We found significant increases in surface water temperatures across lakes at an average rate of + 0.37 °C decade?1, comparable to changes reported previously for other lakes, and similarly consistent trends of increasing water column stability (+ 0.08 kg m?3 decade?1). In contrast, however, deepwater temperature trends showed little change on average (+ 0.06 °C decade?1), but had high variability across lakes, with trends in individual lakes ranging from ? 0.68 °C decade?1 to + 0.65 °C decade?1. The variability in deepwater temperature trends was not explained by trends in either surface water temperatures or thermal stability within lakes, and only 8.4% was explained by lake thermal region or local lake characteristics in a random forest analysis. These findings suggest that external drivers beyond our tested lake characteristics are important in explaining long-term trends in thermal structure, such as local to regional climate patterns or additional external anthropogenic influences. © 2020, The Author(s).

Saline rivers -- Ostracods -- Diet -- Fatty acid markers
Аннотация: Saline rivers are highly productive ecosystems in arid regions. The meiobenthic community (bottom meiofauna) and its dominant representatives are one of the least studied components of these aquatic ecosystems. Ostracods Cyprideis torosa and Heterocypris salina are major consumers among the species of bottom meiofauna in saline rivers flowing into the hyperhaline Lake Elton (Volgograd Region, Russia). We estimated the abundance, biomass and production of C. torosa, the dominant species at the mouth of the polyhaline Chernavka River (average salinity is similar to 30 g l(-1)), and H. salina, the dominant species at the mouth of the mesohaline Bolshaya Samoroda River (similar to 13 g l(-1)), in spring (May) and summer (August). Additionally, we studied the composition and content of fatty acids of the ostracods and their potential food sources (bottom sediments with bacterial-algal mats). We found that the abundance and biomass (wet weight with shells) of C. torosa in the Chernavka River and H. salina in the Bolshaya Samoroda River reached 3.5 x 10(6) ind. m(-2) and 117 g m(-2), and 1.1 x 10(5) ind. m(-2) and 12 g m(-2), respectively. The first species formed on average about 85% of the total abundance and 96% of the total biomass of the meiobenthos, and the second one, about 13% and 31%, respectively. The daily production of C. torosa and H. salina can reach 249 and 36 mg m(-2) ash-free dry weight, respectively. The results indicate that these species may play an important role in the total flow of matter and energy in the studied habitats. Based on the fatty acid (FA) composition of the ostracods and their food sources, it was found that C. torosa mainly consumed diatoms, while H. salina preferred bacteria, cyanobacteria, and green algae. Differences between the species were greater than differences between the bottom sediments from the rivers. It may mean that the ostracods selectively consumed different food items that may be related to the different nutrient requirements of the species. Seasonal changes in the FA compositions of the ostracods were higher than in their food sources (bottom sediments), which also indicates selective feeding of the species.
