Effect of temperature on contents of essential highly unsaturated fatty acids in freshwater zooplankton / M. I. Gladyshev [et al.] // Limnologica. - 2011. - Vol. 41, Is. 4. - P339-347, DOI 10.1016/j.limno.2011.03.001 . - ISSN 0075-9511

Аннотация: In 11 lakes from cold and warm regions we studied the content of highly unsaturated fatty acids (HUFA) in seston (<130?m) and crustacean zooplankton using gas chromatography-mass spectrometry. An increase of temperature correlated with a decrease of HUFA content in zooplankton. A multivariate canonical correlation analyses revealed, that the decrease of HUFA content was related with a decrease of per cent of copepods in zooplankton communities, which are known to have higher HUFA levels in their biomass, than cladocerans. This means that temperature primarily affected the HUFA levels indirectly, via changing of taxonomic structure of zooplankton community, while the homeoviscous adaptation of zooplankton individuals had comparatively lower importance. As found, water temperature was better predictor of HUFA contents of zooplankton, than the fatty acid composition of seston. Thus, it can be predicted, that a probable climate warming will decrease the content of the essential HUFA in freshwater zooplankton with possible negative consequences for animals of higher trophic levels.

Growth rate of Daphnia feeding on seston in a Siberian reservoir: The role of essential fatty acid / M. I. Gladyshev [et al.] // Aquatic Ecology. - 2008. - Vol. 42, Is. 4. - P617-627, DOI 10.1007/s10452-007-9146-7 . - ISSN 1386-2588

Аннотация: Specific growth rates (based on biomass increment in unit time) of Daphnia fed natural reservoir seston from a eutrophic Siberian reservoir were studied during four vegetation seasons in a laboratory flow-through system. Concentrations of particulate C, N, and P in reservoir seston <115 ?m were comparatively high, 1.9, 0.2, and 0.05 mg l-1, respectively; maximum C:P ratio was 259 mol:mol. According to conventional thresholds, concentrations of elements and their stoichiometry did not limit the growth rate of Daphnia. Eicosapentaenoic acid (EPA) in seston significantly effected the growth rates at concentrations up to ?13 ?g l-1 (regression ANOVAR F-test value was 7.91), but not above this concentration. Thus, we consider this concentration of EPA in seston <115 ?m to be the limiting concentration of EPA for the growth of Daphnia (longispina group), i.e., below this concentration EPA was the best single predictor of the growth of Daphnia.

Аннотация: We studied non-consumptive (non-predatory) mortality of Daphnia and Cyclops vicinus during four sampling seasons. Mortality estimations were based on live/dead sorting using special staining and measurements of sedimentation rates for dead individuals, depended on wind speed. Original equations were used for calculations. The estimated specific non-consumptive mortality never had biologically senseless negative values, which were often obtained on the basis of the other ways of mortality estimations, and was in a good agreement with other components of population dynamics. As found, the non-consumptive mortality was the important, often the determinant component of the zooplankton population dynamics.

Gut content analysis of Gammarus lacustris from a Siberian lake using biochemical and biophysical methods / M. I. Gladyshev [et al.] // Hydrobiologia. - 2000. - Vol. 431, Is. 2-3. - P155-163 . - ISSN 0018-8158

Аннотация: We studied the gut contents of Gammarus lacustris from the littoral of Shira lake, a Siberian salt lake, by microscopic analysis in conjunction with measuring of fluorescence of chlorophyll and composition of fatty acids. Gammarus ingested primarily fresh seston, probably settled on the bottom. Additionally, the amphipods obtained essential polyunsaturated fatty acids of ?3 family by selectively consuming bottom sediment particles. A considerable part of the ingested seston comprised cells of Botryococcus sp., which passed the intestinal tract in living form and their photosynthetic activity increased. This viable gut passage was likely one of the causes of bloom of Botryococcus in the littoral. Unlike a number of literature data, there was no selective digestion of any fatty acid species, including polyunsaturated acids, in the intestinal tract.

Аннотация: Asynchronous vertical migrations of calanoid copepods Arctodiaptomus salinus were studied in two stratified lakes in the south of Siberia using the method of two-section enclosures. It was found that the presence of a pronounced thermocline and a depth maximum of phytoplankton (Lake Shira) contributes to the appearance of intensive individual migrations of copepods between areas of the epi- and hypolimnion.

The induction of diapause in Moina by species-specific chemical cues / E. Zadereev, T. Lopatina // Aquatic Ecology. - 2007. - Vol. 41, Is. 2. - P255-261, DOI 10.1007/s10452-006-9062-2 . - ISSN 1386-2588

Аннотация: The ability to change the reproduction mode and produce diapausing eggs, which is prevalent in many zooplankton species, significantly impacts on the evolution and ecology of aquatic communities. The production of diapausing eggs is controlled by multiple effects of biotic and abiotic factors, including infochemicals. We have investigated the effects of chemicals exuded by conspecifics and ecologically close competing congers, Moina brachiata and M. macrocopa, which coexist in the same water body, and by larger Cladocera species (Daphnia magna) on the change of reproduction mode, specific growth rate and fecundity of M. brachiata and M. macrocopa females. The production of gametogenetic eggs in both species was detected only in waters from crowded cultures of conspecifics. The water from crowded cultures of conspecifics reduced the specific growth rate of the juvenile females of both species that later switched to gametogenesis. While it either did not affect (in M. macrocopa) or even increase (in M. brachiata) the specific growth rate of the juvenile females that later reproduced by parthenogenesis. Females of M. macrocopa released significantly fewer neonates in the water from crowded cultures of conspecifics than in all other treatments, while the fecundity of M. brachiata females was the same in all treatments. To understand the phenomenon of diapause induction under the effect of chemical cues in zooplankton, a link between laboratory tests and ecological research should be established, and the chemical composition of the signals should be determined.

Feeding spectra of Arctodiaptomus salinus (Calanoida, Copepoda) using fatty acid trophic markers in seston food in two salt lakes in South Siberia (Khakasia, Russia) / A. P. Tolomeev [et al.] // Aquatic Ecology. - 2010. - Vol. 44, Is. 3. - P513-530, DOI 10.1007/s10452-010-9331-y . - ISSN 1386-2588

Аннотация: During two vegetation seasons (2004-2005), we compared feeding spectra of Arctodiaptomus salinus (Calanoida, Copepoda) populations inhabiting two neighboring salt lakes, Shira and Shunet, Khakasia, Russia, using fatty acid (FA) trophic markers. Sestonic FA composition in two lakes moderately differed, whereas levels of diatom FA markers were higher in Lake Shunet and of Cyanobacteria and green algae markers in Lake Shira. In general, markers in storage lipids-triacylglycerols (TAG) of A. salinus-reflected the differences in sestonic composition of the two lakes. Nevertheless, TAG fraction was also enriched by FA trophic markers of the minor components of seston, which were selectively ingested by the animals. In Lake Shira, A. salinus had significantly higher concentrations of bacterial FA markers in TAG. In Lake Shunet, TAG of A. salinus contained significantly higher relative amounts of 18:4?3, 18:5?3 and C22 polyunsaturated fatty acids (PUFA), which indicated marked contribution of cryptophytes or (and) flagellates into the diet. Laboratory experiments showed feeding on Cryptomonas and sulfur purple bacteria in Lake Shunet and ciliates and colonial picoplankton in both lakes, and generally confirmed the differences in FA trophic markers in A. salinus between the lakes. The two populations of A. salinus markedly differed in levels of essential long-chain PUFA, eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, although the levels of these FA in seston were quite similar between the two lakes. The higher levels of the essential ?3 PUFA in A. salinus in Lake Shunet may be an adaptive response of the animals to a vertical stratification of physico-chemical conditions and significantly higher salinity levels at the boundary of adjacent bottom layer in this lake.

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.

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.

Аннотация: The allelopathic effect of population density on gametogenesis induction of Moina macrocopa (Crustacea: Cladocera) was investigated at varying food concentration, photoperiod, and temperature. The presence of the non-trophic effect of population density on gametogenesis induction was demonstrated. The experiments with single females have shown that if the photoperiod, temperature, and food concentration are favorable for parthenogenesis, the crowding water has the effect of stimulating females into changing the reproduction mode. This effect was enhanced by using a higher density of the population to achieve crowding. The change of reproduction mode occurs in the experiments with populations of M. macrocopa with the achievement of food availability favorable for the parthenogenesis of single females. Chemical interactions between animals are the most obvious explanation for the obtained results.

carbon flux -- inland waters -- lakes -- live -- dead sorting -- non-predatory mortality -- zooplankton carcasses
Аннотация: Zooplankton carcasses are ubiquitous in marine and freshwater systems, implicating the importance of non-predatory mortality, but both are often overlooked in ecological studies compared with predatory mortality. The development of several microscopic methods allows the distinction between live and dead zooplankton in field samples, and the reported percentages of dead zooplankton average 11.6 (minimum) to 59.8 (maximum) in marine environments, and 7.4 (minimum) to 47.6 (maximum) in fresh and inland waters. Common causes of non-predatory mortality among zooplankton include senescence, temperature change, physical and chemical stresses, parasitism and food-related factors. Carcasses resulting from non-predatory mortality may undergo decomposition leading to an increase in microbial production and a shift in microbial composition in the water column. Alternatively, sinking carcasses may contribute significantly to vertical carbon flux especially outside the phytoplankton growth seasons, and become a food source for the benthos. Global climate change is already altering freshwater ecosystems on multiple levels, and likely will have significant positive or negative effects on zooplankton non-predatory mortality. Better spatial and temporal studies of zooplankton carcasses and non-predatory mortality rates will improve our understanding of this important but under-appreciated topic.

Аннотация: The possibility of symbiotic, mutualistic (++) interrelations between epibiontic microalgae (Characidiopsis ellipsoidea, Colacium vesiculosum) and cyclopoids (Cyclops vicinus, Mesocyclops leukarti) in the Bugach recreational reservoir with a bloom of cyanobacteria is demonstrated. Overgrown cyclopoids, compared to those free from microalgae, have advantages in oxygen supply, which may be insufficient in the period of intensive algal bloom. Calculations have shown that oxygen requirements of cyclopoids may be fully satisfied due to C. vesiculosum photosynthetic activity in the dysphotic zone if the density of overgrowth exceeds 1000 algal cells per individual. There is no significant correlation between the natural mortality of crustaceans and the indices of their overgrowth by microalgae.

Аннотация: Seasonality of burden and prevalence of phototrophic (microalgal) epibionts Characidiopsis ellipsoidea, Colacium vesiculosum and Colacium sp. on dominating crustacean zooplankton (Daphnia longispina, Cyclops vicinus and Mesocyclops leuckarti) were studied in a small reservoir Bugach with cyanobacterial bloom. The correlations between the seasonal dynamics of prevalence and the dynamics of others biotic and abiotic factors were calculated. The conclusions were as follows. The substrate species, that determined the development of the epibionts on the three studied crustacean zooplankton, was Daphnia longispina (Cladocera). Despite intensive epibiotic infestation of crustacean zooplankton, epibionts did not appear to have caused non-consumptive mortality of the crustacean zooplankton. But they could have contributed to the Daphnia summer decline by increasing mortality due to its consumption by planktivorous fishes. The phototropic epibionts may successfully coexist with cyanobacterial bloom. The possible role of the epibionts in changing nutrient fluxes in pelagic food web is discussed.

Аннотация: We tested a comparatively new method of tracing of natural food webs, compound-specific isotope analysis (CSIA) of fatty acids (FA), using laboratory culture of Daphnia galeata fed Chlorella vulgaris and Cryptomonas sp. In general, Daphnia had significantly lighter carbon stable isotope composition of most fatty acids, including essential, than those of their food, microalgae. Thus, our results did not support the pivotal premise of the FA-CSIA application for food web analysis, i.e., transmitting the isotope 'signal' of essential FAs to consumers from their food without any modification. Moreover, the values of isotope fractionation of particular FAs in the consumer relative to its food were not constant, but varied from 1.35‰ to 7.04‰. The different isotope fractionation (depletion) values of diverse FAs in consumer were probably caused by different processes of their synthesis, catabolism and assimilation. More work is evidently to be done for correct interpretation of results of FA-CSIA during field studies for tracing of natural food webs. © 2015 Elsevier GmbH.

Аннотация: This study assesses the comparative sensitivity and possibility of obtaining fast results of various methods of biotesting for several surfactants: Tween 85, sodium dodecyl sulfate (SDS), Fairy dishwashing gel, and Mif washing powder. The following test organisms are used for the study: luminescent bacteria Photobacterium phosphoreum (Beijerinck), preparation of Ecolum luminescent bacteria, unicellular algae Scenedesmus quadricauda (G.M. Smith), infusorian Paramecium caudatum (Ehrenberg), and crustacean Daphnia magna (Straus). It has been revealed that Fairy dishwashing gel possesses the strongest toxicity against the studied test objects. Daphnia and algae are most sensitive to the effects of Fairy and SDS, protozoan and luminescent bacteria are most sensitive to SDS, and Ecolum is most sensitive to Mif washing powder. The tested aquatic organisms and Ecolum are most tolerant to the effect of Tween 85. © 2016, Pleiades Publishing, Ltd.

Аннотация: Zooplankton populations can at times suffer mass mortality due to non-predatory mortality (NPM) factors, and the resulting carcasses can be captured by sediment traps to estimate NPM rate. This approach assumes sinking to be the primary process in removing carcasses, but in reality, carcasses can also be removed by ingestion, turbulent mixing and microbial degradation in the water column. We present mathematical formulations to calculate NPM from sediment trap data by accounting for carcass removal by processes in addition to sinking, and demonstrate their application in a study in Lake Shira, Russia. Carcass abundance of the major calanoid copepod Arctodiaptomus salinus decreased with depth, indicating the effect of carcass removal from the water column. The estimated NPM values (0.0003-0.103 d(-1)) were comparable with previously reported physiological death rates. We further used independent data to partition carcass removal due to detritivory, turbulent mixing and microbial degradation. Estimated ingestion by the amphipod Gammarus lacustris could account for the disappearance of copepod carcasses above the traps. Wind-driven turbulence could also extend the carcass exposure time to microbial degradation. Collectively, these water column processes would facilitate the remineralization of carcasses in the water column, and diminish the carcass carbon flux to the benthos.

Effects of zebra mussels on cladoceran communities under eutrophic conditions / I. Feniova [et al.] // Hydrobiologia. - 2018. - P1-18, DOI 10.1007/s10750-018-3699-4 . - ISSN 0018-8158

Аннотация: The purpose of this study was to determine how zebra mussels affected cladoceran community structure under eutrophic conditions. We conducted a mesocosm study where we manipulated the presence of zebra mussels and the presence of large-bodied Daphnia (Daphnia magna and Daphnia pulicaria). We also conducted a complimentary life-table experiment to determine how water from the zebra mussel treatment affected the life history characteristics of the cladoceran species. We anticipated that small- and large-bodied cladoceran species would respond differently to changes in algal quality and quantity under the effects of zebra mussels. Large-bodied Daphnia successfully established in the zebra mussel treatment but failed to grow in the control. We did not observe positive relationships between food concentrations and cladoceran abundances. However, the phosphorus content in the seston indicated that food quality was below the threshold level for large-bodied cladocerans at the beginning of the experiment. We believe that zebra mussels quickly enhanced the phosphorus content in the seston due to the excretion of inorganic phosphorus, thus facilitating the development of large-bodied Daphnia. In conclusion, our results suggest that zebra mussels can alter the phosphorus content of seston in lakes and this can affect the dynamics of crustacean zooplankton. © 2018 Springer International Publishing AG, part of Springer Nature

zooplankton -- nonpredatory mortality -- numerical modeling -- Arctodiaptomus -- salinus
Аннотация: In deep stratified lakes, the processes of growth and mortality of zooplankton populations result in uneven vertical distributions of living and dead organisms in a water column. The carcasses in the water are removed by sinking, degradation due to microbial decomposition and detritivory, etc. In the case of the epilimnion maximum of zooplankton, provided that the degradation prevails over the sinking, the downward flux of carcasses exponentially decays with depth. This vertical profile of dead organisms, demonstrating the decline in meta- and hypoliminon, can be described by the numerical model presented in this paper. The model approximation of the field data makes it possible to determine non-predator mortality rate m and degradation rate D in relative terms (m/v and D/v, vsinking velocity) or absolute values (with defined v). For the case of the copepod population of Arctodiaptomus salinus in Lake Shira, the calculated m and D (medians of 0.13 and 0.26 day(-1), respectively) were in a good agreement with the literature data. This method also gives the advantage of using the depth-dependent sinking velocity v.

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: It has been shown that the main drivers of the dynamics of cladoceran and copepod abundances can be predators (fish), the quantity and/or quality of food in terms of the contents of eicosapentaenoic acid, phosphorus and nitrogen in the seston under eutrophic conditions. In experimental mesocosms under eutrophic conditions, we found that, fish did not affect the quantity and quality of food resources for crustaceans. In the second half of experiments, however, dominance shifted from copepods to cladocerans. This was due to the improvement of the food quality for cladocerans in terms of the carbon-to-phosphorus ratio in the seston rather than to fish predation. Under eutrophic conditions, fish reduced the biomass of both cladocerans and copepods without changing the ratio between them.
