trophic level
Three following periods were distinguished in the Krasnoyarsk Reservoir in 2000−2009: with low, middle, and high water levels. The largest number of phytoplankton species and infraspecific taxa (193) was found at a middle water level. Cyanophyta gave way to Bacillariophyta, which is indicative of the decrease in the trophic level of the reservoir. In terms of phytoplankton biomass and saprobic index, water quality in the reservoir corresponds to the third class and β-mesosaprobic zone.

A total of 264 species and infraspecific taxa of algae was found in phytoplankton of the Vygozero Reservoir. Bacillariophyta (45%), Chlorophyta (32%), and Chrysophyta (9%) were represented by the largest number of species. Data on the peculiarities of the ecological and floristic composition of phytoplankton, and also on species−indicators of the ecological state and water quality, are given in the paper. Changes in the taxonomic structure of phytoplankton consisting in the increase in the number of species−indicators of a rather high trophic level and organic contamination, were registered in the reservoir. Long-term data (1971−2008) on the quantitative indices of phytoplankton development in the northern part of the Vygozero Reservoir subjected to the influence of sewage of the Segezha Pulp and Paper Mill were analyzed. Saprobiological state of the studied area of water was assessed.

Investigations were carried out at 208 sampling stations located in water bodies and watercourses of Ukraine. It has been found that Dreissena polymorpha and D. bugensis occurred on the shells of mollusks of the family Unionidae in 40 and 13 water bodies, respectively. The influence of the fouling on mollusks was investigated.

The diatom fouling of the Minke whales (little picked whales) in Antarctica have been studied. It was established that the dominant species was Bennettella ceticola (Nelson ex Bennett) Hîlmes, accompanied by Grammatophora marina (Lyngb.) Kütz., Fragilariopsis kerguelensis (O'Meara) Hust. and Nitzschia media Hant. The quantitative characteristics (numbers and biomass) of the diatom films on the whales' skin were determined.

Paper deals with results of study of periphyton, formed in the secondary settling tanks of the municipal waste water treatment plant (Minsk, Belarus.) It was shown that by structural organization it is similar to periphyton of the natural waters. At the same time it was characterized by exceeding of destruction over production and high content of heavy metals and nutritive elements (nitrogen and phosphorus). Use of periphyton for the after-purification of the sewage water after biological treatment in aerotanks can significantly decrease content of the pollutants, first of all heavy metals and nutritive elements (nitrogen and phosphorus).

sanitary state
The most widely used methods of bioindication were analyzed. The Pantle−Buck, Shannon−Weaver, and Goodnight−Whitley indices, and also the Zahner method, were used in assessing the sanitary state of the Rybinsk and Gorkiy reservoirs in terms of macrozoobenthos organisms. These indices were calculated for different sections of the reservoirs. It has been found that in the Gorkiy Reservoir, the deep water section of which is assigned to α−β-mesosaprobic zone with the tendency to α-mesosaprobic zone, the degree of contamination of the water and bottom sediments is higher than that in the Rybinsk Reservoir. In terms of the state of macrozoobenthos, both reservoirs are characterized as moderately contaminated water bodies.

Peculiarities of the organic matters destruction in bottom sediments of the technogeneous water bodies have been outlined. Decomposition of organic matters was shown to occur mainly anaerobically, at this role of methanogenesis and sulfate reduction was also notable.

Seasonal and diurnal dynamics of the freshwater benthic heterotrophic nanoflagellates feeding on bacteria was studied by method of the "stained sediments". Velocity of the bacteria consumption depended on density of the bottom sediments and was not limited by the food concentration, because relation bacteria/flagellate significantly exceeded 1000 : 1.

Paper deals with results of monitoring of the quantitative and functional characteristics of the peripheral blood cells of different fish species of the middle section of the Krasnoyarsk reservoir over the years 2000−2009. Seasonal dynamics of the oxygen metabolism of the blood cells of different fishes was characterized by similar changes of the non-specific resistance in the spawning and post-spawning period under different level of the water filling of the reservoir.

mass of a specimen
Relationship between 137Cs specific activity and the mass of a specimen in benthophage fishes taken from various water bodies of the Kiev region was studied in 1986−2009. In Cyprinus carpio (L.), Carassius auratus gibelio (Bloch), and Carassius carassius (L.), 137Cs specific activity increased with increasing the mass of a specimen. In Abramis brama (L.) and Blicca bjoerkna (L.), vice versa, the specific activity of 137Cs decreased with increasing the mass of a specimen. It is likely that relationship between 137Cs specific activity and the mass of a specimen (age) in benthophage fishes is conditioned by physiological peculiarities of each species.

For the first time a composition of the macro- and meiofauna of the specific biotope - algal balls was described for the Azov-Black Sea basin. The algal balls, collected in the Sivash Bay (the Sea of Azov) at the depth 0.5−1.5 in summer 2009, were formed mainly by fragments of the green alga of the genus Chaetomorpha (Ch. Aerea or Ch. Linum). Macrofauna comprised representatives of Coelenterata, Oligochaeta, Polychaeta, Crustacea, Gastropoda, meiofauna -Foraminifera, Kinorincha, Turbellaria, Nematoda, Harpacticoida, Ostracoda, Acarina (of eumeiobenthos), and Oligochaeta, Polychaeta, Amphipoda, Isopoda (of pseudomeiobenthos).
