The analysis of Ust-Tegussky oil field formation waters are made, the cultures of SRB are isolated from these waters and their taxonomic status is determined. The formation waters which are using for the maintenance of intra sheeted pressure on the Ust-Tegussky oil field, are characterized by a moderate mineralization (23.2 g/l) and contain sulfate (8.4 mg/l). The sulfate-reducing enrichment culture was isolated from the studied waters and contained three bacterial strains by results of TGGE. Fragments 16S rRNA genes of the strains Y1 and Y2 were genetically close to Desulfovibrio alaskensis and D. psychrotolerans with similarity of 99.0 and 95.0%, respectively. Strain Y2 was isolated in pure culture and partially characterized. The phylogenetic analysis of almost full sequence of 16S rRNA gene of strain Y2 showed that it is the most close to a type strain of D. psychrotolerans of isolated from the saline lake and the similarity 96.5% suggests description of a new species. It is shown that new sulfate-reducing bacteria are inhabitants of the formation waters arriving with extracted oil.

Keywords: sulfate-reducing bacteria, underground formation waters, oil deposits, Desulfovibrio.

The water chemical composition and characteristics of the algal periphyton were studied in 25 rivers and streams with different levels of anthropogenic load within Primorskii krai, Russia. Cod and ammoniac dissolved nitrogen are the most unambiguous indicators of the total anthropogenic impact. Organic dissolved phosphorus and nitrates can also be used as indicators of human-caused eutrophication in the Razdolnaya River, characterized by the highest level of eutrophication. the number and biomass of periphyton alga are quite variable even within similar streams. The spices composition and saprobity index (S) calculated from it are more stable. The saprobity indexes shows less spatial variability than chemical composition of the river water. Nevertheless, the correlation between the saprobity index and concentrations of ammonia forms of nitrogen is observed, as well as between the trend in saprobity index of the Razdolnaya River for the last 20 years and dynamics of pollutants received by the river.

Keywords: chemical composition of river waters, nutrients, water quality, algae of periphyton, saprobity index.

Fruit Germination of Some Representatives of the Family Sparganiaceae Rudolphi Under Laboratory Conditions.

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

e-mail: eugenybeliakov@yandex.ru

This paper considers fruit germination patterns in representatives of the family Sparganiaceae which are the most widespread in the European part of Russia: Sparganium emersum Rehm. (subgenus Xanthosparganium), Sparganium erectum L. and Sparganium microcarpum (Neum.) Raunk. (subgenus Melanosparganium). It is shown that after the dissemination fruits of all the studied species do not germinate immediately, both intact and after different pre-sowing treatment (scarification). It is found that under laboratory conditions a long period of moist cold stratification positively affects germination ability of S. emersum and S. microcarpum fruits, as opposed to fruit of S. erectum. In all other experiments, fruits of S. microcarpum did not germinate or sprout sporadically. Fruits of S. erectum did not germinate, regardless of the different conditions of storage and pre-sowing treatment. Long-term dry storage of S. emersum fruits under room conditions, leads to a decrease in laboratory germination ability, and only a subsequent stratification of the fruits makes it possible to significantly increase this characteristic.

Keywords: Sparganium, germination of fruits, lag-time, laboratory percentage of fruit germination, germination period.

This study was conducted in April–October 2009–2011 to investigate the species composition and seasonal changes in concentrations of planktonic heterotrophic nanoflagellates in two small rivers and Sheksna River which run through Cherepovets, a large industrial city. A total of 48 species and forms of colorless flagellates were recorded in the rivers. The three-year average abundance and biomass of heterotrophic nanoflagellates accounted 5788–6164 cells/ml and 252–266 mg/m³, correspondingly in the small rivers and 4450 cells/ml and 194 mg/m³– in the littoral zone of the Sheksna River. In the small rivers maximum values (10.1–11.6 thousand cells/ml and 591–654 mg/m³) were recorded more offen in the second half of summer. A high positive correlation was found between the biomass of single bacterial cells and biomass of heterotrophic nanoflagellates. In the hot summer of 2010 with anomalously high water temperatures the abundance and biomass of heterotrophic nanoflagellates in all the rivers were considerably higher than in other years.

Keywords: heterotrophic nanoflagellates, species composition, abundance, biomass, small rivers.

Downstream migration of young of the year Dolly Varden char Salvelinus malma from the spawning tributary of Lake Kurilskoye lake was studied. It is demonstrated that this migration is an essential stage of the life cycle of this species. Both alevins and fry of Dolly Varden char performed the first feeding migration. It lasted for about one month in the examined creek – from early June to mid July. The migration came to the end by the beginning of sockeye salmon spawn in the creek. Clear diurnal dynamics was inherent for the migration – it occurred only in the dark time of the day. The mass migration from the creek was caused by the deficiencies of habitats and unfavorable feeding conditions.

Keywords: Dolly Varden char, young of the year, downstream migration, Kurilskoye Lake.

Linear Growth of Sparsely Rakered Whitefish Coregonus lavaretus lavaretus (L.) (Coregonidae) in the Babinskaya Imandra (Imandra Lake).

Institute of the North Industrial Ecology Problems KSC RAS, 184209 Apatity, Academgorodok, 14а, Russia

e-mail: zubova@inep.ksc.ru

This study investigated changes in the structure of catches and growth rate of whitefish in the background regions of Lake Imandra (Babinskaya Imandra) in different periods of the Lake transformation (1996–1997 and 2011). A reduction in the number of age groups with a reliable increase in the observed size/weight characteristics and back-calculation of fish lengths (TL) have been found. The increase of growth rate, in turn, has led to the naturally earlier achievement of optimal linear dimensions of first spawning fish and to an earlier age of entry of males and females in the spawning population. No effect of whitefish puberty on its growth rate have been shown.

Keywords: background regions, Imandra Lake, sparsely rakered whitefish Coregonus lavaretus lavaretus (L.), linear growth rate.

The article concerns studies of changes of biomarker P-450 and novel serotonin-modu­la­ting anticonsolidation protein (SMAP) in the brain, liver and gills of eastern bystryanka (Alburnoides bipunctatus eichwaldii (Filippi, 1863)) and Caucasian river gobies (Neogobius constructor (Nordmann, 1840)), caught in the rivers of Azerbaijan Republic polluted with indus­trial wastes. The levels of both proteins in the fish tissues were evaluated with indirect im­mu­ne-en­­zyme assay. It was shown that both indexes, especially SMAP, had different patterns of chan­ges in the tissues of bystryanka and gobies which is perhaps, related to different eco­logical pe­cu­­liarities of the animals of these species.

Keywords: cytochrome P-450, serotonin-modulating anticonsolidation protein, eastern bystryanka, Caucasian river gobies, indirect im­mu­ne-en­zyme assay, brain, liver, gills.

The pro-oxidant and antioxidation plant responses and changes in their anatomical parameters in relation to industrial pollution are detected. Submerged plants are more subjected to a negative impact of sewages compared to semi-submerged plants.

The Effect of Glass Roughness on the Formation of Fouling Communities and Monocultures.

Chelyabinsk State University, 454021 Chelyabinsk, str. Brother Kashirinykh, 129, Russia

e-mail: korfish@mail.ru

This study investigates bio-fouling of rough glass slides in the gradient of deepennings from 7 to 270 µm and from 2 to 10 mm. А severalfold increase in abundance, biomass and diversity of various aquatic organisms is observed on uneven glass surface as compared to the even one. Different size deepennings serve as “cell” to be occupied by attached and mobile forms of various specialization. Later a more complex structure of fouling communities is formed even on the slightest unevenness of the glass.

Keywords: glass, deepenning, biomass, number, periphyton.
