“…The combined lipid extracts were filtered, dried by passing through anhydrous Na 2 SO 4 layer, and evaporated at 35 °C. FA methyl esters (FAMEs) were prepared in a mixture of methanol:sulfuric acid (20:1, v/v) at 90 °C for 2 h as previously described (Makhutova et al 2012). FAMEs were analyzed on a gas chromatograph (GC) equipped with a mass spectrometer detector (model 6890/5975C, Agilent Technologies, Santa Clara, CA, USA) and a 30 m long × 0.25 mm internal diameter HP-FFAP capillary column (Agilent Technologies, Santa Clara, CA, USA).…”

Aquatic invertebrates are valuable dietary sources of essential polyunsaturated fatty acids, eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3), for fish. Phylogeny, diet, and various ecological factors affect the fatty acid composition of aquatic invertebrates. We focused our study on the effect of ecological factors to a cosmopolitan species inhabiting lakes that differed in salinity, temperature, and presence/absence of predators (fish). To avoid the effect of phylogeny, which strongly influences the fatty acid composition of animals, we studied several populations of one cosmopolitan benthic species, Gammarus lacustris Sars. We found that differences in fatty acid percentages of G. lacustris were mainly affected by differences in their diets. Some populations preferred dinoflagellates, cryptophytes, green algae/cyanobacteria, and bacteria; other populations selected diatoms; and still other populations consumed zooplankton or allochthonous (terrestrial) organic matter. Примечание [U1]: The name of the Institute has been changed already. So this is the new name The salinity and presence/absence of fish affected the contents of EPA and DHA in G. lacustris. Populations from saline and fishless lakes had significantly higher contents of EPA and DHA. Thus, stocking of fishless lakes dominated by G. lacustris with fish could lead to a decrease in EPA and DHA contents in the gammarids. We propose that some saline and fishless lakes could be used as a source of gammarids for aquaculture fish feeding.

“…Hence, the quagga mussel can allocate more energy into growth and reproduction, which has been suggested as the major difference in life strategy between the two dreissenids (Ram et al, 2012). While different allocation of energy budget in both species seems to contribute substantially to the shift of dominance, only Makhutova et al (2012) compared the nutrient range (by analytical detection of lipids) between the two dreissenids to determine their energy budget. By contrast, a number of earlier studies on zebra mussel revealed that the body composition of this species contains 5%–10% carbohydrates, 5%–20% lipids, and 60%–70% proteins (Bruner et al, 1994; Nalepa et al, 1993; Smolders et al, 2004; Sprung, 1995; Sprung & Borcherding, 1991; Voets et al, 2006; Walz, 1979).…”

Dreissena rostriformis bugensis (quagga mussel, QM) has spread into areas occupied by an earlier invader, Dreissena polymorpha (zebra mussel, ZM) in Europe and North America. Usually QM displaces ZM within a few years or both species coexist, although the mechanisms driving these outcomes have not been uncovered clearly. In Lake Balaton (central‐eastern Europe), QM displaced ZM in the oligotrophic (food‐limited) basin, whereas they coexist in the eutrophic (food‐rich) basin. Searching for the drivers of interactions in dreissenid assemblages, we compared survival, growth, allometry, shell hardness, biomacromolecule content and superoxide dismutase (SOD) expression (indicating nutrition stress) of dreissenids collected in both basins in a field survey, and in individuals collected from the food‐rich basin and experimentally transplanted (10 weeks) to the food‐limited or food‐rich (i.e. the same) basin. In the field survey, QM from the food‐rich basin showed the greater height increment per unit length than coexisting ZM and food‐limited conspecifics. ZM had the hardest shells of all the mussel populations. In the food‐rich basin, ZM did not differ from QM in weight, protein, and carbohydrate contents, but had higher lipid content and SOD expression. Food‐limited QM, compared to conspecifics from the food‐rich basin, had weaker shells, but their protein, carbohydrate, and lipid contents showed faster increments per unit size, thus adults made up for the initial advantage of the food‐rich population. QM survived better than ZM after transplantation irrespective of the basin. Shells were harder in ZM versus QM and in the food‐rich versus food‐limited conditions. QM grew at both locations, whereas ZM only in the food‐rich basin. The protein and carbohydrate contents were greater in the food‐rich versus food‐limited basin, with no interspecific differences. Lipid content in QM was higher in the food‐limited versus food‐rich basin, whereas the opposite held for ZM. We demonstrated that the dreissenid species could coexist in food‐rich conditions, despite the higher level of stress in ZM (as shown by weaker survival, higher SOD expression), whereas QM displaced ZM under food‐limiting conditions, probably due to the ability to replace missing storage carbohydrates with accumulated lipids. Nevertheless, QM from the food‐limited basin also showed symptoms of nutritional stress (changes in biomacromolecule content, lower shell hardness). Results suggest that the ability to show a rapid change in metabolism could be an important advantage of QM over ZM in their competition.

“…The column temperature program was as follows: from 100°C to 190°C at 3°C/min, 5 min isothermally, then to 230°C at 10°C/min, and 20 min isothermally. Other instrument conditions were as described elsewhere (Makhutova et al 2012). FAME peaks were identified by their mass spectrum compared to those in a database (NIST-2005, Gaithersburg, MD, USA) and to those of available authentic standards (Sigma-Aldrich, St. Louis, MO, USA).…”

Feeding spectra of bivalve mollusks Unio and Dreissena from Kanevskoe Reservoir, Ukraine: are they food competitors or not?

Background: One of the most abundant freshwater invaders is Dreissena polymorpha which provide wide-ranging direct and indirect impacts on the invaded ecosystems. A particularly notable impact on benthic communities is the extinction of native mollusks of the order Unionida. However, the settlement of D. polymorpha on unionid's shells in Kanevskoe Reservoir did not increase native unionid mortality. Since the reason for the successful coexistence of native unionids and invading dreissenids in Kanevskoe Reservoir is unknown, we hypothesized that these mollusks have different feeding spectra. To evaluate this hypothesis, we compared feeding spectra of the mollusks using a fatty acid (FA) marker analysis.
