The role of external and internal phosphorus loading in the lakes eutrophication was estimated according to the published and our own data. The role of plankton and benthos animals was determined in phosphorus excretion and formation of internal nutrient load. It was shown, that the term “eutrophication” is valid both in the anthropogenic and the natural increase in the trophic status of the water body.

Keywords: lakes eutrophication, the phosphorus load, heterotroph phosphorus excretion.

The Structure of the Flagella Apparatus of Heterotrophic Flagellate Klosteria bodomorphis Nikolaev et al., 2003 (Kinetoplastea Excavata).

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

e-mail: mylnikov@ibiw.yaroslavl.ru

The structure of the flagellar apparatus of excavate flagellate Klosteria bodomorphis has been considered. Two naked heterodynamic flagella which are covered by a dense layer of glycocalyx emerge from the single flagellar pocket. The kinetosomes are parallel to each other or are at an acute angle. The dorsal and ventral rootlets run from the kinetosomes and produce dorsal and ventral bands, which have not been connected to each other. The MTR band begins from the wall of the flagellar pocket. The long cytopharynx is supported by the MTR band and additional microtubules. The small fibril and horseshoe-shaped structure lie in the anterior part of the cytopharynx. The vesicular nucleus and Golgi apparatus are of the common structure. The mitochondria is with discal cristae. The kinetoplast as a compact formation has not found. The ressemblance of K. bodomorphis with other free-living kinetoplastids has been discussed.

Keywords: Klosteria bodomorphis, ultrastructure, flagellar apparatus, cytopharynx, Kinetoplastea.

Heterotrophic Bacteria, Zooflagellates and Ciliates in Coastal Waters of the Northeastern Black Sea.

Admiral Ushakov Maritime State University, 353918 Novorossiysk, Lenin ave., 93, Russia

e-mail: selifa@mail.ru

According to microbiological parameters (density, biomass of bacterioplankton) waters in the seaports of Novorossiysk and Tuapse were eutrophic-hypereutrophic and in the resort cities of Gelendzhik and Anapa waters were hypereutrophic. During the periods of abnormally high water temperature (August, 2010) the number of heterotrophic bacteria reached record figures – 12.7–14.2 million ind./ml in recreation zones. Chain like and threadlike forms (57–65%) of bacteria which are typical for coastal pollution of waters prevailed. The abundance of zooflagellates (kinetoplastida) in semi-partically isolated water areas (the port of Novorossiysk, Gelendzhik Bay) reached the level of highly eutrophic waters – 6.2–9.7 million ind./m³. However, the biomass of naked ciliates was 1.5 times lower than their maximum values, which had been registered earlier in coastal waters of the northeasten shelf. The peak of abundance of alien tintinnids of genus Eutintinnus, Tintinnopsis, Amphorellopsis which were introduced via ballast waters of ships were recorded in Novorossiysk Bay. The ratio of tintinnids to the total abundance of ciliates increased 5 times and reached 25–40%. The protozoan developed more poorly in the oil polluted port of Tuapse and Anapa Bay.

Keywords: bacteria, protozoan, trophic level, biological invasion, bays and ports, the Black Sea.

The mitten crab Eriocheir japonica (de Haan, 1835) was used as an indicator species for the biochemical monitoring of different estuarine zones in the Peter the Great Bay (Sea of Japan). The following molecular biomarkers were determined in gills and hepatopancreas of the crabs: the activity of biotransformation enzyme glutathione-S-transferase, antioxidative enzymes superoxide dismutase and catalase, reduced glutathione concentration and lipid peroxidation level, measured as malondialdehyde. The suite of biochemical indicators testify to a good physiological condition of crabs from estuaries of Shkotovka and Sukhodol rivers, and to a depressed one – from Tesnya river. Crabs from the last one had lower activity of catalase, but higher glutathione-S-transferase activity and lipid peroxidation level. Using the data of molecular biomarkers determination, the integral biochemical index was calculated, which made it possible to rank the estuaries on the extent of adverse effects on the biota. The research of the functional condition of the indicator species allows estimating and predicting the biota state under the anthropogenic impact.

Keywords: estuaries, Peter the Great Bay, molecular biomarkers, anthropogenic pollution, mitten crab Eriocheir japonica.

e-mail: laurag@ibiw.yaroslavl.ru

Deformations of hard-chitinized structures (mentum, mandibles) mouthpart larvae of the genus Chironomus, under the influence of organic pollutants were analyzed. A system of quantitative assessment of anomalies of these structures was developed. The indices of severity of mental (ISMtD) and mandibular (ISMdD) deformations were calculated. ISMMD (index of severity of hard-chitinized structures deformations), which is the sum of the above two indices, suggested about contamination of the freshwater ecosystems of toxic organic substances.

Keywords: deformations, mentum, mandibles, genus Chironomus, organic pollution.

Effects of Heavy Metals (Cu, Zn) on the Digestive Glycosidase in Bentophagous Fish from Rybinsk Reservoir Sites with Different Anthropogenic Load.

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

e-mail: golovanova5353@mail.ru

The separate and combined effects of heavy metals (Cu, Zn) at concentrations 0.125 mg/l on the activity of glycosidase (maltase, sucrase, amylolytic activity) in the intestinal mucosa of bream and roach from the Rybinsk reservoir areas with different anthropogenic load have been studied in vitro. Membrane maltase and sucrase in fish from polluted Sheksna reach less sensitive to the effects of Cu and Zn, than in fish from relatively clean Volga reach. On the contrary, enzymes hydrolyzing starch in bream from contaminated area, are more sensitive to the metals studied, especially in summer. The joint action of Cu and Zn (1:1) in most cases reduces the separate effects of these metals on the activity of glycosidase (excluding amylolytic activity) in the studied species.

Keywords: Rybinsk Reservoir, fish, bream, roach, digestive enzymes, glycosidase, heavy metals, copper and zinc.

The indirect competitive immunoenzyme method has been developed for quantitative estimation of microcystins in water (MC-ELISA) using prepared MC-specific polyclonal antibodies. The threshold concentration of the most widespread and highly toxic MC-LR which was reliably detected using MC-ELISA was 0.05 ± 0.01 ng/ml, 50% inhibition concentration was 0.41 ± 0.05 ng/ml, and the concentration range for the quantitative estimation of MC-LR was 0.1–5.0 ng/ml. The MC-ELISA method made it possible to detect MC-LR in water at concentrations 10–20 times lower than the World Health Organization guideline level for drinking water and 100–200 times below the admissible MC concentrations inwaterbodies. A group of cross-reacting MCs and nodularin were detected using MC-ELISA. The method can be applied for monitoring of MC concentrations in waterbodies and drinking water.

Keywords: blue-green algae, microcystins, immunoenzyme analysis.
