Аннотация: We studied fatty acid (FA) composition in samples from bodies and intestinal contents of the littoral amphipod Gammarus lacustris Sars, from the Bugach freshwater reservoir. Simultaneously, samples of seston and bottom sediments were also collected from the reservoir during early August. There were no differences in FA composition of gut contents, seston and sediments of pebbly bottom. Seston was the main food source of Gammarus but some FAs Gammarus got from sediments. The FA composition of G. lacustris and seston from the Bugach freshwater reservoir were compared with those of the animals from the saltwater Lake Shira (Siberia). While FA composition of the two Gammarus populations differed significantly, those of seston were practically similar: the composition of long-chain unsaturated fatty acids, 20:5omega3, 22:6omega3 and 20:4omega6, were significantly higher in animals from saline Shira Lake, whereas 16:1 and 16:0 were higher in the freshwater populations of amphipods from the Bugach freshwater reservoir. Taking into account the relevant literature data, we hypothesise that this difference in C16 acid might be a distinguishing characteristic of FA composition of freshwater and saltwater crustaceans.

A study of the spectral brightness and reflectance of the Krasnoyarsk and Dnepr reservoir systems / A. F. Sid'ko // Oceanology. - 2005. - Vol. 45, Is. 2. - P186-193 . - ISSN 0001-4370

Аннотация: The brightness spectra of the Krasnoyarsk and Dnepr reservoir systems are presented for various periods of their development, from the beginning of their filling to the final stage of their formation. The curves of the surface distribution of chlorophyll a, which were remotely obtained from the brightness coefficient spectra, are found to be monotonic when diatomaceous, green protococcus, and dinophyte algae dominate in the phytoplankton. In the presence of blue-green algae, the curve of the distribution of phytoplankton on the surface is essentially irregular. The irregularities range from tens to hundreds of meters with sharp gradients of the phytoplankton concentration. The negative values of the VI color index change for positive ones when the concentration of chlorophyll a of the phytoplankton in the subsurface layer Cchl > 250-270 mg/m3. This is associated with the change in the species composition of the phytoplankton from the dominating diatom forms to bluegreen algae. Copyright В© 2005 by Pleiades Publishing, Inc.

Agent-based modeling of the complex life cycle of a cyanobacterium (Anabaena) in a shallow reservoir / F. L. Hellweger [et al.] // Limnology and Oceanography. - 2008. - Vol. 53, Is. 4. - P1227-1241 . - ISSN 0024-3590

Аннотация: The cyanobacterium Anabaena flos-aquae and many other phytoplankton species have a complex life cycle that includes a resting stage (akinete). We present a new agent-based (also known as individual-based) model of Anabaena that includes the formation and behavior of akinetes. The model is part of a coupled Eulerian-Lagrangian model and can reproduce the main features of the observed seasonal and interannual population dynamics in Bugach Reservoir (Siberia), including an unexpectedly large bloom in a year with low nutrient concentrations. Model analysis shows that the internal loading of phosphorus (P) due to germination from the sediment bed is ?10% of the total input. However, most of the long-term nutrient uptake for Anabaena occurs in the sediment bed, which suggests that the sediment bed is not just a convenient overwintering location but may also be the primary source of nutrients. An in silico tracing experiment showed that most water column cells (?90%) originated from cells located in the sediment bed during the preceding winter. An in silico gene knockout experiment (akinete formation is prohibited) showed that the formation of resting stages is of critical importance to the survival of the population on an annual basis. A nutrient-reduction management scenario indicates that Anabaena densities increase because they are less sensitive to water column nutrient levels (because of the sediment bed source) than other species.

Associating particulate essential fatty acids of the ?3 family with phytoplankton species composition in a Siberian reservoir / N. N. Sushchik [et al.] // Freshwater Biology. - 2004. - Vol. 49, Is. 9. - P1206-1219, DOI 10.1111/j.1365-2427.2004.01263.x . - ISSN 0046-5070

Аннотация: 1. We studied variation in the composition of fatty acids in the seston of a small freshwater reservoir with changes in phytoplankton composition during four growth seasons. We focused on the dynamics of the ?3 fatty acids because of their potential importance for zooplankton nutrition. 2. Total diatoms were related to the 20:5?3 fatty acid (eicosapentaenoic, EPA) content in seston. Among two dominant diatom genera, Cyclotella was not associated with EPA content. In contrast, there was a significant correlation between Stephanodiscus and the percentage contribution and content of EPA throughout the study. Hence, freshwater diatoms can differ strongly in content of the essential EPA. 3. We considered abundant cyanobacteria as a potential source of 18:3?3 fatty acid (linolenic, ALA) to aquatic food webs. Among four dominant cyanobacteria species, two (Anabaena flos-aquae and Planktothrix agardhii) showed significant correlation with the ALA content of the seston, while the other two (Aphanizomenon flos-aquae and Microcystis aeruginosa) did not. 4. Dinophyta had a relatively high level of 22:6?3 (docosahexaenoic, DHA) for freshwater species and can be also a source of EPA to aquatic food webs. 5. Our results show that various species of diatoms as well as cyanobacteria can be of contrasting nutritional value for zooplankton because of their different content of the essential PUFAs. Diatoms, which are low in EPA, could not be considered as a valuable food, while some field populations of cyanobacteria might be valuable sources of essential ALA.

Аннотация: Sediments from eutrophic reservoir Bugach (Siberia, Russia) were tested for possibility to produce biodiesel. We supposed that the sediments could be a promising biodiesel producer. The major reason of high price of biodiesel fuel is cost of a raw material. The use of dredging sediments for biodiesel production reduces production costs, because the dredging sediments are by-products which originated during lake restoration actions, and are free of cost raw materials. Lipid content in sediments was 0.24% of dry weight. To assess the potential of from sediments as a substitute of diesel fuel, the properties of the biodiesel such as cetane number, iodine number and heat of combustion were calculated. All of this parameters complied with limits established by EN 14214 and EN 14213 related to biodiesel quality. В© 2011 Elsevier Ltd.

Аннотация: The in-situ data on the vertical structure and stability of the vertical stratification of saline Lake Shira over the past decade (2007–2015) are analyzed. Simplified mathematical models have shown that strong wind in the autumn of 2014 together with rather thick ice in the winter of 2015 caused a change in the circulation regime of this water reservoir from meromictic (incomplete mixing) to holomictic (compete mixing). Based on the results obtained, a circulation regime for deep saline lakes located in the continental climate zone, in particular, in the arid zones of Southern Siberia (Khakassia, Transbaikal, and Altai) can be predicted under various climate scenarios of the future. © 2017, Pleiades Publishing, Ltd.

Аннотация: We have studied the fatty acid (FA) contents and composition of cladocerans and copepods from warm and cold lakes. We have found no significant differences in FA percent levels and per carbon contents of cladocerans from warm and cold lakes or of copepods from warm and cold lakes. A discriminant analysis showed that all cladocerans differed from all copepods mainly due to the content of docosahexaenoic acid. Compared to cladocerans, copepods had significantly higher levels of all C22 polyunsaturated FA. Thus, we conclude that cladocerans and copepods in all environments had comparatively invariant taxon-specific compositions and contents of long-chain highly unsaturated fatty acids (HUFAs). According to HUFA content, all studied copepods can be regarded as a valuable food for fish.

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.

Correlations between fatty acid composition of seston and zooplankton and effects of environmental parameters in a eutrophic Siberian reservoir / M. I. Gladyshev [et al.] // Limnologica. - 2010. - Vol. 40, Is. 4. - P343-357, DOI 10.1016/j.limno.2009.12.004 . - ISSN 0075-9511

Аннотация: During two sampling seasons we analyzed on weekly basis fatty acid (FA) composition of seston fraction <130?m and zooplankton fraction >130?m, and compared them using a multivariate canonical correlation analysis (CCA). Besides, we evaluated a possible impact of water temperature and inorganic nutrients on FA composition of the seston and the zooplankton.In spite of significant differences in percentages of several individual FAs, we found very strong canonical correlation (cross-correlation, 1-week lag) between FA composition of the seston and the zooplankton. The most important factor, providing the overall canonical cross-correlation between FA profiles of the seston and the zooplankton fractions was eicosapentaenoic acid (20:5?3, EPA). FA composition of the zooplankton fraction had comparatively poor correlations with taxonomic composition of the zooplankton. Thus, seasonal variations of FA composition of the zooplankton were determined primarily by seasonal changes in FA composition of the seston, rather than by taxonomic differences of FA profiles between rotifers, cyclopoids and cladocerans. FA composition of the seston was strongly affected by its taxonomic composition, namely by that of phytoplankton. According to CCA, the highest factor loadings pertained to diatoms interacting with their marker acids, including EPA, and cyanobacteria and greens, interacting with their marker acids. Ciliates and small rotifers composed considerable and sometimes major part of the seston biomass, but according to CCA their contributions to seasonal variations of the total FA profile of the seston were insignificant. This finding indirectly support the conclusion of the other authors, that the main source of FAs presented in ciliates and rotifers must be sought in algae and that they do not modify FA composition of food consumed, apart from repackaging it.Water temperature was the principal environmental parameter which drove the overall variations of FA composition. Factor loadings for the inorganic nutrients were comparatively negligible. The main contribution in the seasonal variation of FA composition of the seston was given by negative interaction between water temperature and percentage of EPA in the seston.

Аннотация: The degradation dynamics of polyhydroxyalkanoates of different composition has been studied in an eutrophic storage reservoir for two seasons. It has been shown that the biodegradation of polymers under natural conditions depends not only on their structure and physicochemical properties but also, to a great extent, on a complex of weather-climatic conditions affecting the state of the reservoir ecosystem. The molecular genetic analysis of 16S rRNA has revealed bacterial species (clones) probably involved in the degradation of polyhydroxyalkanoates in a model storage reservoir.

Аннотация: During the summers of 1999-2001 the dynamics of polyhydroxyalkanoate degradation in a small recreational eutrophic reservoir was studied experimentally. It has been shown that biodegradation of polyhydroxyalkanoates in the environment is determined by the structure and physicochemical properties of the polymer and by local weather conditions, which influence the state of the aquatic ecosystem. Species (clones) of bacteria able to utilize polyhydroxyalkanoates in the reservoir were identified using molecular phylogenetic analysis of 16S rRNA genes. В© 2007 Elsevier Ltd.

Differentiated influence of quality of seston (Content of C, N, P, and polyunsaturated fatty acids) on rate of somatic and generative growth of Daphnia / A. P. Tolomeev [et al.] // Contemporary Problems of Ecology. - 2012. - Vol. 5, Is. 4. - P450-458, DOI 10.1134/S1995425512040130 . - ISSN 1995-4255

Аннотация: The data set obtained in 19 experiments aimed at studying the growth of Daphnia of the longispina group on natural seston of the Bugach water reservoir (Krasnoyarsk) was used to analyze the relationship between the parameters of somatic and generative growth of the studied animals and the amount and quality of food. Depending on the quality of the seston, two models of the development of Daphnia were proposed. It was demonstrated that, despite the existing positive correlation between somatic and generative growth, a noticeable fraction of the variations of the specific rate of generative production is determined by external factors of the environment, such as the relative content of N and ?-linolenic acid (N: C and ALA: C) in seston.

BIODEGRADATION -- PHENOL
Аннотация: Using experimental microecosystems the kinetics of phenol disappearance in river and reservoir water were investigated. In river water the disappearance kinetics could be described by A first-order equation, the same kinetics took place in reservoir water before and after the period of ''bloom'' of blue-green algae. During the ''bloom'', the phenol seemed to be mineralized by bacteria which grew at the expense of another compound, and the model of best fit was the model of exponential growth and low concentration of the test substrate. In the river, two sections differed according to the difference between the mean values of the specific disappearance rates. In the reservoir these rates were lower than those in the river. In general the specific disappearance rate values did not correlate with the values of initial bacterioplankton density, the concentrations of inorganic nutrients nor the chemical oxygen demand. Conclusions about the integral influence of ecosystems on the disappearance rates and dependence of self-purification kinetics on the type of aquatic ecosystem were made.

Аннотация: Diverse, multidirectional changes in biochemical composition of seston, plankton, and fish fry are detected in the coastal zone of a plain reservoir in the vicinity of a semiaquatic bird colony during vegetation season with extra high water level. Under these conditions, specific patterns of phyto- and zooplankton structure and quantitative characteristics, that, as was found out earlier, result from the vital activity of birds belonging to the family Ardeidae (namely, raising the share of mixotrophic phytoflagellates and copepods in plankton species composition) are leveled out. The main role in this process belongs to decomposition of immersed vegetation in the coastal zone, development of littoral macrophytes, and trophic relationships between algae and invertebrates. However, increase in atmospheric precipitation leads to increase in copepods abundance, which seems to be related to fast and intensive inflow of nitrogen-rich products of birds' vital activity. Due to this, during the whole period of observations, the following tendencies are revealed in biochemical composition of seston, plankton, and fish fry in the vicinity of the bird colony: 1) concentrations of carbon, nitrogen, and phosphorus and their ratios turn out to be auspicious for predominance of diatoms and mixotrophic phytoflagellates, rich in docosahexaenoic acid (DSA); 2) the abundance of phytoplankton, rich in polyunsaturated essential fatty acids (PEFA), favors propagation of those planktonic crustaceans which contain significantly more DSA and are more valuable food items for fish; 3) predominance of zooplankters, rich in PEFA, leads to higher concentration of PEFA in fry fish tissues, which, in certain periods, turns out to be advantageous for successful development and growth of dominant species of fish fry,such as roach, bream, white bream, and perch, by comparison with the test site.
