the Dnieper reservoirs
It has been found that the distribution of periphyton algae of the Dnieper reservoirs depends to a large extent on the type of substratum. Algae communities differing in their species composition, number of species, floristic spectra, spectra of leading families and genera, dominant species, and in the intensity of their development are formed on substrata of different types (solid artificial inorganic substratum, higher aquatic plants, and green filamentous algae). It has been shown that individual taxonomic groups of algae prefer a specified type of substratum.

microscopic algae
In mountain water courses and oligotrophic water bodies, epilithon algae communities are characterized by a high rate of reproduction, by a high intensity of functioning, and by high values of biomass. These features are typical to phytoepilithon of oligotrophic water bodies in different regions of the world. It is thought that the spatial structure and intensive metabolism of microscopic algae are responsible for autonomous cycle of matter, and also for self supply of algae by nutrients. This is supported by high quantitative indices of phytoepilithon development at a low content of nutrients in oligotrophic water bodies.

species composition
indicator species
On the whole 493 species, varieties, and forms of algae were found in plankton of nine lakes located within the basin of the Shuya River (one of the large tributaries of Lake Onega) subjected to the influence of anthropic load. The species diversity of phytoplankton was formed by Bacillariophyta (42%), Chlorophyta (28%), Chrysophyta (11%), and Cyanophyta (10%). The peculiarities of phytoplankton taxonomic structure and of the ecology of individual species of plankton algae of the lakes of the basin are presented. Indicator species of the ecological state of the lakes of the Shuya River basin were revealed. The peculiarities of the species composition of phytoplankton of the lakes depended on the natural conditions of their catchment areas, on the intensity of anthropic load, and also on such factors as their trophic level, coloration, and pH value.

Species and taxonomic diversity of zooplankton communities in the cooling pond of the Khmelnitskiy NPS was studied after putting into operation of the second unit of the nuclear power station and after the introduction of Dreissena polymorpha Pallas. Relationship was established between zooplankton diversity and its other structural indices.

Iran
Data on phytoplankton of various water bodies of Iran are given in the paper. On the whole, 473 species (525 infraspecific taxa) of algae were found in rivers, 495 (548) − in reservoirs, 144 (160) − in lakes, 285 (299) − in swamps, and 293 species (320 infraspecific taxa) − in ponds. Among them, 259 infraspecific taxa were plankton organisms and 258 infraspecific taxa − plankton and benthos organisms. The obtained data were compared and analyzed. The complex of leading taxa was represented by 19 genera, among which 6 genera were typically plankton forms, whereas 7 genera were plankton and benthos forms. The species composition of phytoplankton of various water bodies was compared using the overlap method.

Data on the content of the plant pigments in bottom sediments of the eutrophic Włocławek reservoir in the Vistula River (Poland) are presented. Dependence of the pigments’ concentration on the trophic state of the reservoir: typological properties of sediments and phytoplankton productivity are discussed.

glutamine synthetase
Effect of lead ions on activity of key enzymes of the energy and nitrogen metabolism in the diatom Mayamaea atomus has been studied, and rate of this metal accumulation by the cells has been estimated. Maximal absorption of lead ions occurred in first hours after it was added to the medium. Succinate dehydrogenase and cytochrome oxidase were shown to be more sensitive to 1 MPC of Pb2+ than to 5 MPC, this fact confirmed to complex dependence of respiratory processes in the cells of the diatom on the toxicant concentration. It was revealed that glutamine synthetase practically was not affected by the lead ions of the considered concentration.

The effect of copper, nickel and zinc on growth, photosynthesis and secondary metabolites’ production by the bloom-forming cyanobacteria Microcystis aeruginosa, Oscillatoria agardhii, Anabaena variabilis and Aphanizomenon flos-aquae was investigated. At concentration range 10−7−10−5 mole/l heavy metals can eliminate some Cyanobacteria, inhibit or stimulate growth of others. They are able to promote excretion of various metabolites, including proteins, extracellular polysaccharides, toxins and odors. Elevated excretion of exometabolites negatively effects water quality in the aquatic ecosystems.

The photoluminescence spectra and cell numbers dynamics in different species of green algae after microwave irradiation of decimeter diapason have been studied. It was shown that spectra, photoluminescence intensity and cell numbers changed depending on absorption dose. These indices did not always correlate. Both suppressive and stimulating effect of irradiation was observed.

zooplankton rotifers’ lost coefficient
assessment of ecological state of a water body
When compared two sampling methods − filtration and sedimentation − coefficient of lost of mass small rotifers was calculated, zooplankton numerical density and portions of taxonomic groups in total numbers and ecological state of the Curonian lagoon was determined more precisely. Data obtained using rotifers’ lost coefficient, characterize water body as eutrophic to hypereutrophic, this assessment agrees with assessment by phytoplankton characteristics.
