Заглавие : Saline rivers provide arid landscapes with a considerable amount of biochemically valuable production of chironomid (Diptera) larvae
Место публикации : Hydrobiologia. - 2014. - Vol. 722, Is. 1. - С. 115-128. - ISSN 00188158 (ISSN) , DOI 10.1007/s10750-013-1684-5
Ключевые слова (''Своб.индексиров.''): 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.

Заглавие : Export of biomass and metals from aquatic to terrestrial ecosystems via the emergence of dragonflies (Insecta: Odonata)
Место публикации : Contemp. Probl. Ecol.: Maik Nauka Publishing / Springer SBM, 2016. - Vol. 9, Is. 4. - С. 458-473. - ISSN 19954255 (ISSN) , DOI 10.1134/S1995425516040090
Ключевые слова (''Своб.индексиров.''): abundance--barabinsk forest steppe--biomass--emergence--long-term ecological monitoring--metals--odonata--western siberia--anisoptera (dragonflies)--diptera--insecta--libellula quadrimaculata--odonata
Аннотация: Long-term monitoring of the abundance and spatial distribution of 18 widespread species of Odonata has made it possible to assess their contribution to the export of aquatic productivity that entered the Barabinsk forest-steppe ecosystem. The annual emergence of Odonata varies from 0.8 to 4.9 g/m2 of the land area and from 2.3 to 13.3 g/m2 of the water area, which is 4–5 times larger than that in Diptera. The total flux of organic matter from water to terrestrial ecosystems remains relatively stable (sixfold interannual variability) irrespective of large interannual variations in the abundance of separate species (e.g., 42-fold interannual variability in Libellula quadrimaculata). The metal content was determined in nine Odonata species. Export of metals by dragonflies decreases in the series K > Na > Mg > Ca > Fe > Zn > Cu > Mn > Pb > Ni > Cr > Cd. Therefore, odonates appear to be quantitatively and qualitatively important providers of aquatic resources to the forest-steppe landscape of Western Siberia. © 2016, Pleiades Publishing, Ltd.

Заглавие : Dispersal of midges (Chironomidae, Diptera) on terrestrial area after the emergence from saline lake shira
Место публикации : J. Siberian Fed. Univ. Humanit. Social Sci.: Siberian Federal University, 2019. - Vol. 12, Is. 2. - С. 216-226. - ISSN 19971370 (ISSN), DOI 10.17516/1997-1389-0294
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.

Аннотация: During three field seasons (June-September) of 1997-99 contents of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb were determined in compartments of ecosystem (surrounding soils, bottom sediments, water, zoobenthos, macrophytes, and fish) of a fish and recreation pond situated at the edge of Krasnoyarsk City (Siberia, Russia). Contents of most parts of metals in soils, water, and macrophytes significantly correlated with each other. As concluded, their contents were determined by natural, general, geochemical peculiarities of the region. Heavy metals, contents of which were higher than federal upper limits of concentration, were revealed. In muscles of fish with different feeding spectra-crucian and perch-concentrations of some metals differed significantly; correlation graphs for metals also had different structures. Comparison of our data with those on diverse aquatic ecosystems of Siberia, Europe, North America, and China published in the last decade was carried out. It was concluded that a distribution of heavy metals in the compartments of an aquatic ecosystem presently have to be determined for each particular water body until general regularities are discovered.

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.

Заглавие : Comparison of fatty acid contents and composition in major lipid classes of larvae and adults of mosquitoes (Diptera: Culicidae) from a steppe region
Место публикации : Insect Science. - 2013. - Vol. 20, Is. 5. - С. 585-600. - ISSN 16729609 (ISSN) , DOI 10.1111/j.1744-7917.2012.01582.x
Ключевые слова (''Своб.индексиров.''): amphibiotic insects--essential fatty acids--metamorphosis--mosquitoes--short-chain polyunsaturated fatty acids
Аннотация: Emerging aquatic insects, including mosquitoes, are known to transfer to terrestrial ecosystems specific essential biochemicals, such as polyunsaturated fatty acids (PUFA). We studied fatty acid (FA) composition and contents of dominant mosquito populations (Diptera: Culicidae), that is, Anopheles messeae, Ochlerotatus caspius, Oc. flavescens, Oc. euedes, Oc. subdiversus, Oc. cataphylla, and Aedes cinereus, inhabited a steppe wetland of a temperate climate zone to fill up the gap in their lipid knowledge. The polar lipid and triacylglycerol fractions of larvae and adults were compared. In most studied mosquito species, we first found and identified a number of short-chain PUFA, for example, prominent 14:2n-6 and 14:3n-3, which were not earlier documented in living organisms. These PUFA, although occurred in low levels in adult mosquitoes, can be potentially used as markers of mosquito biomass in terrestrial food webs. We hypothesize that these acids might be synthesized (or retroconverted) by the mosquitoes. Using FA trophic markers accumulated in triacylglycerols, trophic relations of the mosquitoes were accessed. The larval diet comprised green algae, cryptophytes, and dinoflagellates and provided the mosquitoes with essential n-3 PUFA, linolenic, and eicosapentaenoic acids. As a result, both larvae and adults of the studied mosquitoes had comparatively high content of the essential PUFA. Comparison of FA proportions in polar lipids versus storage lipids shown that during mosquito metamorphosis transfer of essential eicosapentaenoic and arachidonic acids from the reserve in storage lipids of larvae to functional polar lipids in adults occurred.

Ключевые слова (''Своб.индексиров.''): 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.

Заглавие : Biological aspects of the associations of biting midges (Diptera: Ceratopogonidae) in two saline rivers of the Elton Lake Basin, Russia
Место публикации : Mar. Freshw. Res.: CSIRO, 2018. - Vol. 69, Is. 6. - С. 906-916. - ISSN 13231650 (ISSN) , DOI 10.1071/MF17125
Ключевые слова (''Своб.индексиров.''): biomarker fatty acids--ceratopogonid larvae--saline rivers--secondary production--algae--bacillariophyta--ceratopogonidae--diptera--palpomyia
Аннотация: We studied species composition, density, biomass and production of larvae of the family Ceratopogonidae in two saline rivers (Volgograd region, Russia). Ceratopoponids make up an important part of macroinvertebrate community in these rivers. Average monthly production (dry weight) of ceratopogonid larvae in the rivers was 3.5-4.8 g m -2 month -1 in May and ?0.9 g m -2 month -1 in August. For the first time, feeding spectra of ceratopogonid larvae, Palpomyia schmidti Goetghebuer, 1934, was studied using fatty acid analyses. The larvae of P. schmidti appeared to selectively consume diatoms and other algae and to avoid bacteria and decomposed dead organic matter (detritus) of low nutritive quality. © CSIRO.
