Phytoplankton Photosynthetic Activity in the Volga River Reservoirs.

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia


Parameters of photosynthetic activity of phytoplankton biomass in the Volga River reservoirs are under consideration. It is shown that in spite of wide limits about the half of all the values are limited by narrower range that makes 0.5–3 mg O₂/(mg · day) for A/B-coefficients, 0.5–3.0 and 1.0 day⁻¹ for P/B-coefficients in euphotic layer and the total water column, respectively. The highest values were ​​obtained in the Upper Volga reservoirs. Turnover time of phytoplankton biomass in the euphotic layer makes 0.2–1.6 days that is 2.1–3.8 times as higher than in the water column from the surface to the bottom. Seasonal changes of the A/B and P/B-coefficients in a reservoir are more variable than the ones within all the cascade in the summer period. A reliable decrease from oligotrophic waters to eutrophic waters testifies the indicator significance of A/B and P/B-coefficients.

Keywords: phytoplankton, biomass, primary production, A/B and P/B-ratios, Volga River reservoirs.

To Ecology and Morphology of Thalassiosira incerta Makarova (Bacillariophyta).

*The Nizhny Novgorod Lobachevsky State University, 603600 Nizhny Novgorod, Pr. Gagarina, 23, Russia

**Institute for Biology of Inland Waters RAS, 152742 Borok, Russia


Thalassiosira incerta has reached an appreciable level of quantitative development in the Cheboksary Reservoir and Oka River (hundreds of thousands and millions of cells per liter, from tenths to tens of grams per cubic meter). Higher abundance and biomass of this species are recorded during the low-water period (August). And algal bloom, to the extent typical for eutrophic/hypertrophic waters, is observed in the Oka River in its section with a typical river regime not subjected to the reservoir's backwater effect. Our studies make it possible to specify ecology, range and morphological features of the species. River conditions of highly trophic and highly saprobic water courses during dry years are optimal for the species development.

Keywords: Cheboksary Reservoir, Oka River, phytoplankton, diatoms, Thalassiosira incerta, ecology, morphology.

Institute of Biology of the Southern Seas, 299011 Sevastopol, Pr. Nakhimova, 2, Russia


The spatial variability of the vertical structure of bioluminescence intensity has been studied along the Crimean coast in the spring period. The location of the layer with high intensity of bioluminescence has been determined and its dependence on hydrological parameters and thermohaline structure of waters is shown. Structurization of the spatial variability of bioluminescence intensity has been made. Four regions different in the pattern of the vertical distribution of bioluminescence intensity have been distinguished in coastal waters of the Crimean Peninsula.

Keywords: bioluminescence, Black Sea, vertical structure, hydrological characteristics.

*Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

**Institute of Hydroecology and Ichthyology of Scientific Centre of Zoology and Hydroecology NAS, RA, 0014 Yerevan, P. Sevak str., 7, Armenia


The qualitative composition and structure of autumn zooplankton in pelagic zone of Lake Sevan, in years which are characterized by different amount of fish, are described. In October 2013 at increase of the whitefish quantity, the richness of zooplankton species increased insignificantly; the values of trophic coefficient and Shannon index, calculated by number, increased; the specific number of Rotifera and Cladocera decreased. Atypical changes of development parameters of zooplankton invertebrates were marked simultaneously. They were expressed as the increase in the total biomass, due to Cladocera, among which Daphnia (Ctenodaphnia) magna Straus occupied the leading position. The particular changes of zooplankton are discussed.

Keywords: high mountain Lake Sevan, autumn, zooplankton, fish quantity.

The Dependence of Sperm Motility Duration of Ob-Irtysh Basin Coregonidae on Temperature.

State Research and Reproduction Center of Fishery, 625023 Tyumen, ul. Odesskaya, 33, Russia


The sperm motility duration of four whitefish species in the Ob-Irtysh basin: Coregonus tugun, river and lake forms of C. peled, C. lavaretus pidschian and C. nasus has been studied. The sperm motility duration of the species under study depends significantly on the temperature of water used for activation in inverse proportion. The sperm motility duration at the spawning temperature in the range of 0.1–5.0°C amounts to 331±107 sec, and duration of forward movement amounts to 149±44 sec. At temperatures (above 7.1°C) which exceed spawning values, these parameters constitute 190±47 sec and 86±15 sec, respectively. The highest interspecific variability in the sperm motility duration was observed within the temperature range from 0.1 to 2.5°C and above 7.1°C. C. tugun shows less dependence of sperm motility duration on temperature than the other species under study at the temperature of 0.7°C. The total duration and duration of the forward movement of C. tugun sperm are 201 and 108 sec, respectively. When temperature increases up to 13.4°C, the parameters under study decrease 1.2 and 1.1 times only, to 172 and 100 sec respectively.

Keywords: coregonidae, fish sperm, temperature, activation of sperm, sperm motility, forward motility, oscillatory motility.

The Role of Bithyniid Snails (Gastropoda: Bithyniidae), as Hosts of Trematodes of the Family Notocotylidae in Ecosystems of Different Climatic Zones of the West Siberian Plain.

Institute of Systematics and Ecology of Animals, SB RAS, 630091 Novosibirsk, ul. Frunze, 11, Russia


The results of long-term investigations (1994–2012) of an infection rate of trematodes of the family Notocotylidae Lühe, 1909 in the first intermediate hosts (Bithyniidae family) are discussed. The bithyniid snails (11 348 Bithynia troscheli (Paasch, 1842) and 4347 Bithynia tentaculata (Linne, 1758) in 1994–2012 from Western Siberia have been studied. Parthenitae and cercariae of the family Notocotylidae belong to three species: Notocotylus imbricatus Looss, 1894, Szidat; N. parviovatus Yamaguti, 1934 [syn.: N. chionis Baylis, 1928] и Catatropis verrucosa (Frohl.) Odhner, 1905. The extensiveness of infection of bithyniid snails by the trematodes (parthenitae and cercariae) of the family Notocotylidae in rivers basin Ob, Irtich, Karacyk and Chany Lake is analysed. The level of the infection of bithyniid snails by trematodes (parthenitae and cercariae) does not exceed one percent in different reservoirs. The similar data have been obtained during long-term studies in the mouth of the Kargat river, and in the Ob river (near Novosibirsk). The percentage of infected B. tentaculata was significantly higher than of infected B. troscheli in the total (1.79 and 0.32% accordingly, χ2 = 95.1, p<0.001), and in different reservoirs, too. The infected bithyniid snails are recorded in waterbodies of all four basins only in steppe (0.52 ± 0.37%) and forest-steppe zones (0.76 ± 0.07%). Bithyniid snails from waterbodies of the forest zone of the West Siberian Plain were not infected with parthenitae and cercariae of the family Notocotylidae.

Keywords: forest-steppe, steppe, Bithyniidae, Bithynia troscheli, Bithynia tentaculata, Notocotylus imbricatus, Notocotylus parviovatus, Catatropis verrucosa.

Activity of Digestive Enzymes as a Determinant Factor in Localization of Tetrabothrius erostris (Loennberg) (Cestoda: Tetrabothriidae) in Intestine of Herring Gull Larus argentatus Pontoppidan.

Murmansk Marine Biological Institute of Kola Scientific Centre of RAS, 183010 Murmansk, ul. Vladimirskayа, 17, Russia


Herring gulls Larus argentatus (adult and nestling) were investigated. The parameters of their invasion by Tetrabothrius erostris (Cestoda: Tetrabothriidae) were determined. T. erostris parasitizes in posterior and middle parts of a small intestine of adult herring gulls. T. erostris parasitizes in the middle part of the small intestine of nestling herring gulls. High activities of digestive enzymes (protease and glycosidase) and intense processes of cavernous and membrane digestion were recorded in this part of the small intestine of gulls. Apparently, features of physiology of digestion of herring gulls and peculiarities of development of tetrabothriid are factors which determined localization T. erostris in the small intestine of herring gulls.

Keywords: herring gull, Tetrabothrius erostris, localization in small intestine, protease, glycosidase.
