“…Nonmethylene interrupted FA, that is, 5,11–20:2, 7,13–20:2, and 7,13–22:2, and many others have also been identified (Demidkova, ). They have been confirmed only in marine bryozoans and have not been proven either in our work or by Makhutova et al (). It is possible to speculate that their presence is a taxonomic marker of marine bryozoans.…”

“…The freshwater bryozoan Plumatella emarginata has been analyzed for the FA content, which was similar to the FA content of marine bryozoans; the content of 20:4n‐6 reached 2.7% of total FA (Makhutova et al, ). Heptadecanal has been identified as a major aldehyde in eight marine bryozoans (Berdyshev, Getmanova, Svetashev, & Kubanin, ), which demonstrates the presence of plasmalogen lipids as part of total lipids.…”

Freshwater bryozoan Pectinatella magnifica was collected from a sand pit (South Bohemia). The total lipids after extraction from lyophilized bryozoans were analyzed using high-performance liquid chromatography/high-resolution negative tandem electrospray mass spectrometry. A total of 19 lipid classes were identified, including N-acyl-substituted phospholipids, that is, N-acylphosphatidylethanolamine and N-acylphosphatidylserine in their plasmenyl forms. Based on gas chromatography/mass spectrometry of 3-pyridylcarbonyl (picolinyl) esters, a very unusual fatty acid was identified, namely 24:7n-3 (all-cis-3,6,9,12,15,18,21-tetracosaheptaenoic acid). The presence of polyunsaturated fatty acids in individual classes is very specific: arachidonic and eicosapentaenoic acids being predominantly bound as amides in N-acyl phospholipids, that is, diacyl-N-acylphosphatidylethanolamines (NAPtdEtn), plasmenyl-N-acylphosphatidyl ethanolamines (PlsNAPtdEtn), diacyl-N-acylphosphatidylserines (NAPtdSer), and plasmenyl-N-acylphosphatidylserines (PlsNAPtdSer). While 24:6n-3 was identified in the sn-2 position of several phospholipids, 24:7n-3 was identified in only two plasmalogens, that is, PlsNAPtdEtn and PlsNAPtdSer. Thanks to the tandem mass spectrometry, we managed to identify the position of all acyl groups in both diacyl- and also in alkenyl-acyl-(plasmenyl) molecular species of N-acylphospholipids. The identification of the molecular species of N-acyl-substituted phosphatidylethanolamine and phosphatidylserine, including their plasmalogen forms, in the freshwater bryozoan P. magnifica has enabled the identification of endogenous cannabinoid precursors.

“…Most likely, when more samples are analysed throughout the world, the range of variations will be expanded. Indeed, variations of EPA+DHA contents in the benthic larvae of aquatic insects were ~10-fold (Makhutova et al, 2016). Besides, the average LC-PUFA flux to land area was found to vary from 0.04 to 4.39 mg•m -2 •year -1 across numerous biomes.…”

For future estimating of potential limitation of some terrestrial consumers by food quality in global scale, the water-land fluxes of essential polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA), with the biomass of emergent aquatic insects in several biomes were estimated. The water /land area ratios for each biome were calculated by dividing the water area of each biome by its terrestrial area. Data on insect emergence from water bodies (g of dry mass m-2 year-1), were generalized and averaged for each biome.From available data, EPA and DHA contents (mg g-1 dry mass), in the biomass of emergent aquatic insects were calculated first so that annual fluxes of PUFA to land area via aquatic insect emergence could be estimated for each biome. A high variability of PUFA fluxes occurred between the biomes, ranging from 0.04 to 4.39 mg•m-2 •year-1. In this study, the aquatic PUFA supply to land area appeared to be significantly lower than that of a previous global average estimate. This finding indicates that a putative limitation of some terrestrial consumers by food quality, namely by the supply of aquatic PUFA, may be more severe than was previously determined.

“…However, using data on FA profiles, obtained in this study, feeding habits of some species at the studied sites might be specified. For instance, Siberian spined loach C. melanoleuca , which had the maximum levels of Σ20:1, but the minimum level of 20:5n‐3 (Table ), might prefer Mollusca, Hirudinea, and Oligochaeta, rich in 20:1 (Makhutova et al, ), to insect larvae, rich in EPA (Makhutova et al, ). Stone sculpin P. knerii had a high level of 24:1n‐11, which is characteristic of marine harpacticoid copepods, when feeding on diatom algae (Nanton & Castell, ).…”

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.
