Аннотация: The efficiency of the transfer of gamma-emitting radionuclides in food chains, including macrophytes, zoobenthos, and bentho- and ichthyophagist fish, was estimated in the radiation-polluted region of the Yenisei river. Significant differences in the efficiency of the transfer of natural and technogenic radionuclides between components of different trophic levels were revealed. Substantial species-related differences in the accumulation of radionuclides in ichthyophagist fish from food were revealed. В© 2012 Pleiades Publishing, Ltd.

Artificial radionuclides in fish fauna of the Yenisei River in the vicinity of the Mining-and-Chemical Combine (Siberia, Russia) / T. Zotina, E. Trofimova, A. Bolsunovsky // Radioprotection. - 2011. - Vol. 46, Is. 6 SUPPL. - S75-S78, DOI 10.1051/radiopro/20116649s . - ISSN 0033-8451
Аннотация: Activities of radionuclides were measured in five species of fish (grayling, dace, crucian carp, pike, cod) sampled in the Yenisei River (Siberia, Russia) in the vicinity of the Mining-and-Chemical Combine (ROSATOM) from 2007 to 2010, with a gamma-spectrometer (Canberra, USA). The analyses of samples of organs and tissues of fish species revealed artificial (46Sc, 51Cr, 54Mn, 58,60Co, 59Fe, 65Zn, 85Sr, 99Mo, 103,106Ru, 137Cs, 141,144Ce) and natural (7Be, 40K) radionuclides in fish organs and tissues, including edible ones. The major percent (up to 80%) of 137Cs and 40K activity occurred in muscles of fish species, which also contained considerable percentages of 60Co (up to 70%) and 65Zn (up to 20%). Seasonal changes in the intake of artificial radionuclides by zoobenthos-feeding fish species (grayling and dace) were recorded and they were followed by an activity concentration increase in internal organs. The dramatic increase in radionuclide intake by grayling coincided with the change of diet source. Hence, the feeding behavior of fish can change the fluxes of artificial radionuclides in the Yenisei River. The most effective diet transfer of a radionuclide from gammarus to grayling (muscles and total body) was recorded for 40K (1.3) and much less effective for artificial nuclides.

Аннотация: A one-dimensional mathematical model of the Yenisei river ecosystem including hydrological, ecosystem and radioecologicl blocks has been developed. The model was used to evaluate contribution of different processes (transfer by water masses, dilution, radioactive decay, bioaccumulation) into self-purification of the river water from a radiation pollution. The pollution density of ecosystem components (bacteria, phyto-, zooplankton, phyto-, zoobenthos, detritus) with 137Cs and 32P is calculated.

Аннотация: Spatial distribution of Gammarus lacustris in Lake Shira and growth of young specimens that feed on lake biota were studied. The amphipods have been shown to inhabit the littoral, sublittoral and the upper aphytal zones of the lake on stony-sandy soil and silted sand. The young and adult individuals stay apart. The young live in submerged or semi-submerged vegetation in the littoral, the adults in the sublittoral and upper aphytal zones. Maximum density of amphipods was encountered in the areas influenced by human activity. The feeding experiments revealed that the lake plankton is a more important food source for G. lacustris than any other food species. The specific growth rate measured was 0.039 d-1, with a length increment 0.095 mm d-1.

Amino acid composition of epilithic biofilm and benthic animals in a large Siberian river / A. A. Kolmakova [et al.] // Freshwater Biology. - 2013. - Vol. 58, Is. 10. - P2180-2195, DOI 10.1111/fwb.12200 . - ISSN 0046-5070

Аннотация: We studied amino acid (AA) composition of epilithic biofilms and zoobenthos near the shore at a middle section of the Yenisei River (Siberia, Russia). We hypothesised that there was an imbalance between the composition and content of amino acids in the biofilm and its consumers, the zoobenthos, as well as between those in the zoobenthos and fish. Based on monthly sampling from 2007 to 2010, there was seasonal variation in AA profiles in the epilithic biofilms, probably caused by the succession of microalgal and cyanobacterial species. Overall, there was an imbalance in the percentage of the essential amino acids (lysine and histidine) between benthic animals and their food (the epilithic biofilm), which suggests that benthic animals may be limited by food quality. Moreover, the zoobenthos had a significantly higher content of AA, relative to carbon, than the biofilm. Based on sampling in 2012, there was an imbalance between the AA profiles of zoobenthos and that of their main consumer, the Siberian grayling (Thymallus arcticus), particularly in the percentages of two essential amino acids, lysine and leucine. In terms of overall content of essential amino acids, the nutritional value to fish of gammarids, which have recently invaded the river, was significantly lower than that of indigenous taxa, trichopteran and chironomid larvae.

Water moss as a food item of the zoobenthos in the Yenisei River / G. S. Kalachova [et al.] // Central European Journal of Biology. - 2011. - Vol. 6, Is. 2. - P236-245, DOI 10.2478/s11535-010-0115-0 . - ISSN 1895-104X

Аннотация: Bryophytes are abundant in streams and are a habitat for many invertebrates, but their contribution to the diet of fluvial zoobenthos is still debated. To estimate the amount of bryophyte-derived organic matter assimilated by benthic invertebrates, we used a combination of fatty acid and stable isotope analyses during a four-year monthly study of a littoral site in the Yenisei River (Siberia, Russia). Acetylenic acids, which are highly specific biomarkers of the water moss Fontinalis antipyretica, were found in lipids of all dominant benthic animals: gammarids, ephemeropterans, chironomids and trichopterans. The dominant zoobenthic species, Eulimnogammarus viridis, had maximum levels of the biomarkers in its biomass during winter, and minimum levels in summer. The zoobenthos in the studied site regularly consume and assimilate bryophyte-derived organic matter as a minor supplemental food. This consumption increases in winter, when the main food source of the zoobenthos, epilithic biofilms, are probably scarce. В© 2010 Versita Warsaw and Springer-Verlag Wien.

Seasonal dynamics of fatty acids in the lipids of water moss Fontinalis antipyretica from the Yenisei River / G. S. Kalacheva [et al.] // Russian Journal of Plant Physiology. - 2009. - Vol. 56, Is. 6. - P795-807, DOI 10.1134/S1021443709060090 . - ISSN 1021-4437

Аннотация: Identification of lipid fatty acids (FA) and studying of their seasonal dynamics in water moss Fontinalis antipyretica from the Yenisei River were carried out by means of gas chromatography-mass spectrometry. FA composition of water moss was notable for a relatively low level of saturated acids and predominance of polyunsaturated acids (PUFA) with double bonds (accounting for more than 30% of total FA) and polyunsaturated acids with double and triple bonds (acetylenic acids, accounting for more than 40% of total FA). Among PUFA, ?- and ?-linolenic (18:3?3 and 18:3?6), arachidonic (20:4?6), and eicosapentaenoic (20:5?3) acids prevailed. Relative content of PUFA from ?3-family was the greatest in spring, and the level of PUFA from ?6-group was essentially the same throughout all the seasons. In the biomass of water moss, we identified seven acetylenic acids; among them octadeca-9,12-dien-6-ynoic (6a,9,12-18:3), octadeca-9,12,15-trien-6-ynoic (6a,9,12,15-18:4), and eicosa-11,14-dien-8-ynoic (8a,11,14-20:3) acids were predominant. For the first time, in the lipids of water moss we identified an acetylenic eicosa-11,14,17-trien-8-ynoic acid (8a,11,14,15-20:4). Relative content of acetylenic acids in the total FA was great throughout the entire period of investigation with the peak accumulation in summer. Owing to a steadily high level in the biomass of water moss and the lack of other producers of these acids in the ecosystem, acetylenic FA are highly specific biochemical markers useful for the investigation of trophic interactions between higher aquatic plants and zoobenthos.

Seasonal dynamics of long-chain polyunsaturated fatty acids in littoral benthos in the upper Yenisei river / N. N. Sushchik [et al.] // Aquatic Ecology. - 2007. - Vol. 41, Is. 2. - P349-365, DOI 10.1007/s10452-006-9065-z . - ISSN 1386-2588

Аннотация: We studied composition and concentrations of fatty acids (FAs) in benthos from pebbly littoral region of the Yenisei River in a sampling site near Krasnoyarsk city (Siberia, Russia) for 1 year from March 2003 to February 2004. Special attention was paid to major long-chain polyunsaturated fatty acids (PUFAs) of the ?3 family: eicosapentaenoic acid (EPA, 20:5?3) and docosahexaenoic acids (DHA, 22:6?3). In phytobenthos, which was dominated by diatoms, the annual maxima of EPA and DHA pool occurred in spring and early summer. In zoobenthos, EPA and DHA pool peaked in autumn, due mainly to an increase of the biomass of dominant taxa (gammarids) and to a moderate increase of the PUFA content per body weight. Seasonal peaks of EPA in overwintering insect larvae (chironomids and caddisflies) generally coincided with those of biomass of these larvae, while there was no such trend for amphipods and oligochaetes. In spring and early summer, the main part of ?3 PUFA, 40-97% of total amount, in the littoral region was contained in biomass of producers, i.e., benthic microalgae, and in autumn it was transferred to primary consumers-benthic invertebrates, which contained ?76-93% of total ?3 PUFAs.

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.

Metal Concentrations in the Ecosystem and Around Recreational and Fish-Breeding Pond Bugach / M. I. Gladyshev [et al.] // Water Resources. - 2001. - Vol. 28, Is. 3. - P288-296, DOI 10.1023/A:1010400807660 . - ISSN 0097-8078
Аннотация: Data of two field studies were used to analyze the concentrations of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb in the water, bottom deposits, zoobenthos, fish, and macrophytes of the Pond Bugach and in the soils near the pond. It was established that the majority of metals in the soils and bottom deposits correlate and their concentrations are governed by the universal geochemical factors of the region. The heavy metals were recognized that originate from anthropogenic sources and their concentrations were found to exceed the maximum admissible values for different components of the ecosystem. Five types of heavy metals migration were recognized in the soil-bottom deposits-zoobenthos-fish chain and in macrophytes. Statistically significant difference was found to exist between the concentrations of some heavy metals in the muscles of fish species with different food types (crucian carp and perch) as well as between the correlations of metals. The recorded concentrations were compared with the concentrations of metals measured in the last decade in other limnetic ecosystems in Siberia, Europe, North America, and China.

Аннотация: During three field seasons (June-September) of 1997-99 contents of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb were determined in compartments of ecosystem (surrounding soils, bottom sediments, water, zoobenthos, macrophytes, and fish) of a fish and recreation pond situated at the edge of Krasnoyarsk City (Siberia, Russia). Contents of most parts of metals in soils, water, and macrophytes significantly correlated with each other. As concluded, their contents were determined by natural, general, geochemical peculiarities of the region. Heavy metals, contents of which were higher than federal upper limits of concentration, were revealed. In muscles of fish with different feeding spectra - crucian and perch - concentrations of some metals differed significantly; correlation graphs for metals also had different structures. Comparison of our data with those on diverse aquatic ecosystems of Siberia, Europe, North America, and China published in the last decade was carried out. It was concluded that a distribution of heavy metals in the compartments of an aquatic ecosystem presently have to be determined for each particular water body until general regularities are discovered.

Аннотация: During three field seasons (June-September) of 1997-99 contents of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb were determined in compartments of ecosystem (surrounding soils, bottom sediments, water, zoobenthos, macrophytes, and fish) of a fish and recreation pond situated at the edge of Krasnoyarsk City (Siberia, Russia). Contents of most parts of metals in soils, water, and macrophytes significantly correlated with each other. As concluded, their contents were determined by natural, general, geochemical peculiarities of the region. Heavy metals, contents of which were higher than federal upper limits of concentration, were revealed. In muscles of fish with different feeding spectra-crucian and perch-concentrations of some metals differed significantly; correlation graphs for metals also had different structures. Comparison of our data with those on diverse aquatic ecosystems of Siberia, Europe, North America, and China published in the last decade was carried out. It was concluded that a distribution of heavy metals in the compartments of an aquatic ecosystem presently have to be determined for each particular water body until general regularities are discovered.

Аннотация: Highly unsaturated fatty acids (HUFA), namely eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA), which are essential for many animals, including humans, are mainly produced in aquatic trophic webs. In fast-flowing rivers, macrozoobenthos is the main source of HUFA for fish and may be particularly vulnerable to thermal alterations associated with climate change. We studied benthic communities in a unique natural ecosystem: the Yenisei River downstream of the dam of Krasnoyarsk Hydroelectric Power Station with very low temperature in summer because of discharge of cold water from deep in the reservoir and its tributaries with high summer temperature. This natural experiment' allowed to get rid of confounding factors, such as differences in light, seasonality, geology (biogeochemistry) and biogeography (regional species pools). As found, in spite of an increase of biodiversity and rates of daily production in warm rivers compared with cold sites, DHA and partly EPA production of zoobenthos decreased with the increase of temperature because of changes in species composition. Thus, in a climate warming context, we can predict a decrease of production of these HUFA by river zoobenthos and thereby a diminishing of their supply for fish and next to humans.

Fluxes of biomass and essential polyunsaturated fatty acids from water to land via chironomid emergence from a mountain lake / E. V. Borisova [et al.] // Contemp. Probl. Ecol. - 2016. - Vol. 9, Is. 4. - P446-457, DOI 10.1134/S199542551604003X . - ISSN 1995-4255

amphibiotic insect emergence -- biogenic fluxes from water to land -- Chironomidae -- mountain landscape -- polyunsaturated fatty acids -- Chironomidae -- Hexapoda
Аннотация: The taxonomic composition, seasonal dynamics, and emergence intensity of chironomid adults (the Chironomidae family) emerging from Oiskoe mountain oligotrophic lake (Western Sayan, Southern Siberia) have been established. The value of the annual emergence of chironomid adults averages 0.42 g wet weight m-2 in the lake area and approaches the value of potential emergence, which is calculated based on the estimate of zoobenthos secondary production. For the first time the fatty-acid composition and contents of essential omega-3 polyunsaturated fatty acids (PUFAs) are compared between the larvae and adult stages of chironomids. The PUFA content per wet weight unit in adults is more than 7 times higher than that in larvae. The PUFA flux per lake area unit resulting from the chironomid emergence amounted to 1.752 mg m-2 y-1, which is over 10 times lower than the global estimate for the emergence of amphibiotic insects. Calculations show that the PUFA flux brought with the chironomid emergence per land unit of the studied mountain territory is very low when compared to that for other landscapes, with the exception of the shoreline part of the territory with a width of 15 m, in which the PUFA flux is comparable to that in productive landscapes. © 2016, Pleiades Publishing, Ltd.

Аннотация: В результате многолетних исследований (2010-2013) получены данные по накоплению урана-238 в гидробионтах разных трофических уровней экосистемы р. Енисей. Пробы водного мха (Fointinalis antipyretica), зообентоса (Philolimnogammarus viridis и Ph. Cyaneus), сибирского хариуса (Thymallus arcticus) и щуки (Esox lucius) отбирали в районе ранее зарегистрированного повышенного содержания урана в воде р. Енисей (вблизи радиоактивных сбросов Горно-химического комбината Росатома). Показано, что уран способен эффективно накапливаться из воды в биомассе всех исследованных гидробионтов. Максимальные коэффициенты накопления (КН) урана получены для водного мха, что многократно превышает КН урана для зообентоса и мышечной ткани рыб. Средние значения КН урана для зообентоса статистически значимо превышают КН в мышцах рыб за весь период наблюдения. Не выявлено статистически значимых отличий в накоплении урана рыбами разного трофического уровня (хариус и щука)
The aim of the research was a comparative evaluation of the intensity of uranium-238 accumulation in the biomass of aquatic organisms, occupying different trophic levels in the ecosystem of the Yenisei river. Previously, uranium-238 at concentrations higher than the background ones was detected in water and sediment samples of the Yenisei River collected close to the discharge site of one of the Rosatom facilities (the Mining-and-Chemical Combine). However, radioecological studies of the Yenisei River ecosystem have not focused on uranium isotopes in aquatic organisms so far. The toxic effects of uranium on living organisms are known to be based on its both radioactive and chemical properties. We conducted a study on accumulation of uranium-238 in aquatic organisms at different trophic levels in the Yenisei River ecosystem between 2010 and 2013. We collected samples of aquatic moss (Fointinalis antipyretica), zoobenthos (Philolimnogammarus viridis and Ph. cyaneus), arctic grayling (Thymallus arcticus), and pike (Esox lucius) from the Yenisei region at a distance of 85-90 km downstream of Krasnoyarsk (5-10 km downstream of the radioactive discharge of the Mining-and-Chemical Combine). Data on samples are shown in Table 1. We determined uranium concentration in the samples of aquatic organisms by neutron activation analysis, in water - by ICP-MS (Table 2). The study shows that uranium can be effectively concentrated from water and accumulate in the biomass of all aquatic organisms used in experiments. The highest uranium concentration factors (CFs) were obtained for aquatic moss, and they were several times higher than the uranium CFs for zoobenthos and fish muscles. Based on the uranium concentration from water, all aquatic organisms of the Yenisei River used in this study can be ranked as follows: aquatic moss > gammarids > grayling = pike. No statistically significant difference has been found between uranium accumulation by fish of different trophic levels (Arctic grayling and pike). The uranium CFs obtained in this study is comparable with the literature data on the CFs of artificial radionuclides for aquatic moss and fish of the Yenisei River
