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 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.

Comparison of seasonal dynamics of the essential PUFA contents in benthic invertebrates and grayling Thymallus arcticus in the Yenisei river / N. N.

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.

Saline rivers provide arid landscapes with a considerable amount of biochemically valuable production of chironomid (Diptera) larvae / T. D. Zinchenko [et al.] // Hydrobiologia. - 2014. - Vol. 722, Is. 1. - P115-128, DOI 10.1007/s10750-013-1684-5 . - ISSN 0018-8158

Chironomid larvae -- Essential fatty acids -- Saline rivers -- Secondary production
Аннотация: Saline rivers are supposed to be 'hot spots' of high biological productivity in arid landscapes. To test this, we quantified the production of chironomid larvae, because river production is known to be transferred to arid landscapes primarily by birds fed on these larvae. In addition, we studied the potential biochemical quality of the larvae for birds based on the essential highly unsaturated fatty acid (HUFA) contents in their biomass. We studied species composition and measured production of chironomid larvae in two saline rivers (Volgograd region, Russia). We also evaluated the fatty acid composition and contents of the dominant taxa and estimated the flux of HUFA from the studied saline rivers to land via chironomid potential emergence. Average monthly production of chironomids measured for only 1 month, August, was quite comparable to annual production in some freshwater rivers. All the dominant chironomid larvae had comparatively high essential eicosapentaenoic acid contents, especially Cricotopus salinophilus, which showed the highest value, reported for Chironomidae. The monthly flux of HUFA from the studied rivers to land due to the chironomid potential emergence was roughly comparable to the global average estimation of annual water-land HUFA export via emerging insects.

fatty acids -- triacylglycerols -- polar lipids -- gammarids -- aquatic larvae of insects
Аннотация: The composition and content of fatty acids (FAs) in total lipids, triacylglycerols (TAG) and polar lipids (PL) in dominant groups of benthic invertebrates: gammarids (Gammaridae, Amphipoda), chironomid larvae (Chironomidae, Diptera), caddisfly larvae (Trichoptera) and mayfly larvae (Ephemeroptera) were studied in the Yenisei river. For the first time data on the FA composition of species belonging to Trichoptera (Insecta) are presented. The groups of aquatic insect larvae and gammarids weakly differed in total content of essential polyunsaturated fatty acids (PUFAs). Hence, the strong invasion of gammarids which occurred in the last decades in the Yenisei river should not result in a decrease in potential yield of essential PUFA in the ecosystem and corresponding decrease in food resource quality for fish in respect to PUFA content. Significant differences in biomarker FAs in TAG were found which correlated to specific food sources. Different levels of long-chain PUFA in PL of the invertebrates are discussed in relation to the genetic ability of particular taxa to form these FAs. (C) 2002 Elsevier Science Inc.

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.

Fatty acid composition and content in chironomid species at various life stages dominating in a saline Siberian lake / O. N. Makhutova [et al.] // Contemp. Probl. Ecol. - 2017. - Vol. 10, Is. 3. - P230-239, DOI 10.1134/S1995425517030064 . - ISSN 1995-4255

amphibiotic insect emergence -- Chironomidae -- fatty acids -- life stages -- saline lake -- Chironomidae -- Glyptotendipes barbipes -- Hexapoda
Аннотация: This paper studies the fatty acid (FA) composition and content of essential polyunsaturated fatty acids (PUFAs) in the biomass of larvae and adults of chironomids from the saline Shira Lake. Species of different genera significantly differ in their larvae FA composition and essential PUFA content, and they also occupy different ecological niches: Chironomus species with a low PUFA content (0.2–0.3 mg g–1 of wet weight) inhabit a deepwater zone of the lake, while Glyptotendipes barbipes species that were richer in PUFA (2.3 mg g–1 of wet weight) dwell in the littoral of the lake. The biochemical differences are likely related to different feeding spectra of these taxa and can also be explained by the phylogenetic factor. A comparison does not find differences in the PUFA content in larvae and adults in the samples of the same species G. barbipes; i.e., we do not confirm the data on an increase in the content of these acids during the metamorphosis of chironomids. Thus, the data on the PUFA content in larvae can be used in calculations of PUFA fluxes through chironomid emergence from water bodies; however, the taxonomic affiliation of the emerged chironomids should be taken into consideration due to the high variability in the PUFA content in Chironomidae species. © 2017, Pleiades Publishing, Ltd.

Dispersal of midges (Chironomidae, Diptera) on terrestrial area after the emergence from saline lake shira / I. A. Vitkovskaya, E. V. Borisova, N. N. Sushchik // J. Siberian Fed. Univ. Humanit. Social Sci. - 2019. - Vol. 12, Is. 2. - С. 216-226, DOI 10.17516/1997-1389-0294 . - ISSN 1997-1370

Аннотация: We studied the number of midges (Chironomidae, Diptera) on the terrestrial area where flows of organic matter and essential polyunsaturated fatty acids (PUFA) provided by the emergence of the amphibiotic insects from saline steppe Lake Shira were dispersed. Records of midge specimens captured on sticky traps showed that 50 and 95 percent of the emerged adults of the Glyptotendipes and Polypedilum genera occurred within 25-m and 100-m strips surrounding the lakeshore, respectively. The areas of these strips were calculated along with quantification of flows of chironomid biomass and essential PUFA per land area unit based on data of previously measured export. For the 25-m lake-surrounding strip, where 50% of midges swarmed, the annual import of dry biomass and PUFA accounted for 1.5 g · m-2 and 15 mg · m-2, respectively. Further, the 100-m wide strip, where 95% of the midges were registered, got the annual flows of 0.7 g dry weight · m-2 and 7.2 mg PUFA · m-2. The calculated values of PUFA import were similar to measurements in relatively productive landscapes. The number of midges captured on the site located near the most productive lake part was the lowest among all the studied near-lake sites. This site of the lakeshore is part of a national preserve, where a great number of insectivorous birds live or stop. The lower abundance of swarming chironomids on this site was likely related to intensive consumption by terrestrial animals, i.e., birds, for obtaining necessary doses of essential compounds. © Siberian Federal University.
