phototrophic plankton of the syderotrophic meromictic Lake Kuznechikha (Republic Mari El, Russia).

Institute of Ecology of the Volga River Basin, Russian Academy of Sciences, 445003, Samara region, Togliatti, Komzina str., 10, Russia

e-mail: mvumansk67@gmail.com

During summer thermal stratification, a broad transition zone with hypoxic conditions is formed in meromictic ferruginous Lake Kuznechikha between the thermocline and the main gradient of water mineralization. In this zone, chemical composition of water undergoes ecologically significant transformation, due to overlapping gradients of nutrient concentrations and redox conditions. In this paper, we presented an analysis of strongly vertically structured community of prokaryotic and eukaryotic phototrophs developing in the lake as a whole and especially in the transition zone. In early summer 2009 a sequence of phototrophic organisms with depth in order Chlorophyceae → Chromatiales → Chloroflexales → Euglenales → Chlorobiales was observed in transition zone, while cyanobacteria were almost completely absent. Biomass maximum of anoxygenic phototrophic bacteria was located between the peaks of phototrophic picoplankton and euglenoids. Such а coexistence of oxygenic and anoxygenic phototrophs in a wide range of depths is highly unusual and sharply distinguishes the Lake Kuznechikha from water-bodies with sulphide-containing monimolimnion.

Keywords: anoxygenic phototrophic bacteria, phytoplankton, phototrophic picoplankton, vertical distribution, stratification, meromictic lakes.

Golden Algae (Chrysophyta) in plankton of the Volga river reservoirs: taxonomic structure, Dynamics of Diversity and Abundance.

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

e-mail: korneva@ibiw.yaroslavl.ru

Published and original data for the period of 1953–2004 concerning the taxonomic composition and ecological and geographical characteristics of planktonic chrysophytes of nine reservoirs of the Volga River basin have been analyzed. Analysis of the relationship between species richness and some abiotic and biolimnological parameters has been carried out. The degree of floras similarity in the reservoirs has been studied. Patterns of changes in specific species richness and biomass of golden algae in the longitudinal profile of the Volga River reservoirs are identified. The long-term dynamics (1954–2011) of diversity, abundance and biomass of chrysophytes in the Rybinsk Reservoir are analyzed. Decline in diversity and biomass of golden algae in direction from the Upper to the Lower Volga, in accordance with the geographical zoning is revealed. It is shown that a long-term increase in the diversity and biomass of golden algae in the Rybinsk Reservoir (Upper Volga) is positively correlated with an increase in water temperature and precipitation.

Keywords: phytoplankton, golden algae (Chrysophyta), Volga River basin reservoirs.

Accumulation of heavy metals and morphophysiological responses of two common species of submerged hydrophytes (Elodea canadensis Michx. and Potamogeton perfoliatus L.) from habitats with differen levels of pollutions were studied. The investigations were carried out in the surroundings of the metallurgical plant, the town of Revda, Sverdlovsk oblast, Russia (upstream and downstream Revda River). It was shown that hydrophytes from polluted habitats (downstream) differed from plants of a less polluted site (upstream) by the higher accumulation of HMs, the greater thickness of a leaf, the larger cells and chloroplasts. Plants in the polluted site were characterized by a high photosynthetic pigments, while flavonoid content in the leaves was lower. The identified trends indicate a high adaptive potential of these plant species and their ability to inhabit the environment polluted with metals and other pollutants.

Keywords: hydrophytes, leaf mesostructure, photosynthetic pigments, flavonoids, heavy metals.

Heterotrophic Flagellates of Sphagnum Bogs and Lakes in Usman Pine Forest, Voronezh Oblast, Russia

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

e-mail: ap.mylnikov@rambler.ru

The species composition and morphology of heterotrophic flagellates from 4 sphagnum bogs and 6 lakes in Usman pine-forest, Voronezh Oblast, Russia is described. A total of 71 species from 5 supergroups (Amoebozoa, Opistoconta, Rhizaria, Archaeplastida and Excavata) have been recorded. Faunal similarity of flagellates local complexes in the studied water bodies is extremely low. The maximal species richness has been registrated in the terrace dammed lake with a marsh watershed; minimal richness has been detected in the driest sphagnum bog. Floodplain lakes were characterized by maximal and minimal species specificity, whereas the terrace lakes and bogs had an intermediate level of species specificity. Most species were represented by Rhizaria and Excavata. Among Rhizaria Cercomonadida and Glissomonadida were dominant; Euglenoidea and Kinetoplastida prevailed among Excavata. Only three predatory species have been recorded: Rhynchobodo armata, Goniomonas truncata and Alphamonas edax. Some of the revealed species are also known for sea waters, that indicates their euryhalinity. Bordnamonas tropicana has been found in a fresh water body for the first time. The descriptions, drawings and photographs of 16 species are given, taking into account the morphological features of their cells.

Keywords: heterotrophic flagellates, fauna, morphology, Voronezh Oblast, Russia, Usman pine forest, lakes, sphagnum bogs.

Heterotrophic Nanoflagellates in Water and Column Sediments of the Rybinsk Reservoir: Species Composition, Abundance, Biomass and the Role in the Consumption of Bacteria.

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

e-mail: dkos@ibiw.yaroslavl.ru

The abundance, biomass and taxonomic composition of heterotrophic flagellates (HNF) were determined in water bottom and sediments of a large lowland mesoeuthrophic reservoir (Rybinsk reservoir, Upper Volga). The role of HNF in the consumption of the bacterial production was estimated. A total of 56 species from 15 large taxa were identified. Amongthem 35 species were found in plankton and 45 species were found in benthos. The Orders Kinetoplastida, Choanomonada and Chrysomonadida had the greatest diversity. Abundance and biomass of HNF averaged 991 ± 326 cells/ml and 41.4 ± 14.1 mg/m3 in water and (236 ± 61) × 103 cells/ml and 10.7 ± 4.0 µg/ml in bottom sediments respectively. The biomass of HNF averaged 11.2% of the bacterial biomass in the water column and only 2% in sediments. Flagellates were the important factor which controlled the bacterioplankton while they consumed on average 32.3% of its daily bacterioplankton production whereas their influence on bacteriobenthos was insignificant as they consumed on average only 2.0% of bacteriobenthos production.

Keywords: heterotrophic flagellates, bacteria, water column and bottom sediments of the reservoir.

The composition and structure of zooplankton in small waterbodies (lakes and puddles) of Pechora Bay coastal marches were studied. The investigated water bodies were attributed to three ecotopes (low, medium and high marshes), distinguished according to the degree of soil salinity and vegetation quality on the coastal strip along ecological profile that is perpendicular to the coast. It was revealed that species composition and zooplankton abundance are dependent on a ecotope type and water mineralization. The trophic community structure shows the difference of food resources in the studied ecotopes.

Keywords: zooplankton, coastal marsches, composition, structure.

Experimental Study of the European River Lamprey, Lampetra fluviatilis (L.), Migratory Behaviour in the Period of Juveviles Initial Dispersion.

Institute of Ecology and Evolution, Russian Academy of Sciences, 119071 Moscow, Pr. Leninskii, 33, Russia

e-mail: a.o.zvezdin@gmail.com

Mechanisms of initial dispersion of the European river lamprey early larvae resident and anadromous forms have been experimentally explored. The courses (channel flow and underflow), type of bottom and illumination are the key factors influencing the beginning and the end of downstream migration. Larvae leaving pebble ground of the spawning area when there is underflow, and illumination reduced to the night level, and then they migrate downstream in the channel stream. It is shown that the individuals dispersing from the spawning areas have switched to exogenous feeding. The end of the dispersion occurs after larvae reach oozy habitats of the riverbed, where they could find optimal feeding conditions.

Keywords: European river lamprey Lampetra fluviatilis, early larvae behavior, mechanisms of migration, channel flow and underflow, preference for different types of bottom.

The influence of phenol and its derivatives (4-chlorophenol, 4-nitrophenol, 2,4-dinitrophenol) on peptidase activity in 5 species, differed by the feeding character was investigated. Under in vitro conditions phenol and its derivatives in concentrations 0.5-0.6 mmol/l, usually decrease the peptidase activity in the intestine of bream, silver bream and especially pike. The extent of their influence depends on the fish species, as well as the localization of the enzymes (mucosa or chyme). Peptidase activity in sander and perch in fact does not change in the presence of these toxic substances. It is assumed that the effects of phenol and its derivatives are largely dependent on the structure of peptidases: in the representatives of the family Percidae the enzymes are relatively stable to the action of phenol and its derivatives. In the representatives of the families Cyprinidae and Esocidae the peptidases are sensitive to the action of phenols.

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

e-mail: kryloff@ibiw.yaroslavl.ru

The impact of light deprivation, geomagnetic deprivation and the combination of these factors on the germ cell mitosis in roach embryos and the size of hatched prelarvae have been studied. It is shown that the geomagnetic deprivation leads to changes in the ratio of blastomeres that pass through initial and final phases of mitosis and the increase in the mitotic index of germ cells, the number of chromosomal abnormalities and the length of prelarvae. An additive effect of the embryos exposure to the combination of light and geomagnetic deprivation is expressed as a significant increase in the number of aberrant mitosis and the length of prelarvae.

Keywords: mitosis, light, germ cells, blastomeres, hypomagnetic field.
