Two approaches to zoobenthos cenosis distinguishing were analyzed by example of the Kyiv reservoir: bionomic and biotopic. Application of bionomic approach to the cenotic structuring of zoobenthos using the V. A. Brotskaya's and L. A. Zenkevich's method enabled to distinguish in the Kyiv reservoir eight cenosis, comprising 18 to 38 species with total biomass 7.68 to 4604.46 g/m2. Unification was suggested of the zoobenthos cenosis nomination by name of species, dominating by the density index √(bP) and their ecological characteristic.

Comparative analysis of the functional characteristics of phytoplankton of the Baikal and Khanka lakes, and also of the reservoirs of the Volga and Yenisey rivers, differing in their energetic and mineral resources has shown that their algae cenoses differ in the dimensional composition of dominant species. It has been found that the development of phytoplankton depends on the content of nutrients, its photosynthesizing activity - on the content of nutrients and light regime, whereas the intensity and relationship between the processes of production and decomposition - on hydrological conditions and morphometric peculiarities of water bodies.

As a result of long-term investigations, it has been found that periphyton algae communities of the same type belonging to the association Lyngbyo putealis-Oscillatorietum brevis are formed in the sections subjected to considerable heating in all the studied cooling ponds of thermal and nuclear power stations of Ukraine. The presence of thermophilous species of blue-green algae among diagnostic taxa is peculiar to this association.

Positive correlation was stated between the reed (Phragmites australis) biomass and nutrients (N, P) concentration in water. In the lakes of the Ukrainian Polissia growth of the trophic status leads to growth of the productional characteristics of the reed. Values of its phytomass in the water bodies of different trophic status were determined.

Ecological and sanitary state of the river section of the Kanev Reservoir subjected to the influence of anthropic load of Kiev was assessed in terms of microphytobenthos communities. The worst state of the aquatic ecosystem was registered in the central part of the city and in the estuary of the discharge canal of the Bortnichi Station of Aeration.

Investigations carried out in January − March in water bodies of different types have shown that during this period the contribution of microbial processes in bottom sediments to organic mater decomposition accounted for 68−97%. In silts of lakes with a high productivity, organic matter was decomposed only by anaerobic way.

bioindication.
The activity of the acid DNase and acid RNase was determined in gills and liver of the common bream and blue bream from different areas of the Rybinsk reservoir. The highest activity of nucleases in common breams was noted within the clean areas of the reservoir. The depression of the acid nucleases activity is supposed to serve as marker of the water bodies' toxic pollution. Almost complete lack of dependence between environment pollution and nucleases' activity in the blue bream complicates use of this species for biochemical indication of the water bodies' pollution.

Results of the study of a set of metals (Al, Fe, Mn, Zn, Pb, Cu, and Cr) in the water of the Desna River are given in the paper. The peculiarities of the distribution of Al(III), Mn(II), Cr(III), and Cu(II) among their suspended and dissolved forms are discussed. The role of the dissolved organic matter in the process of metal migration was also studied. It has been found that humus substances are of considerable importance in binding Al(III), Fe(III), Cu(II), and Mn(II). The contribution of the dissolved forms of the above mentioned metals to the composition of their anionic complexes accounted for 51.3−71.5%. Neutral complexes of metals with carbohydrates (12.7−40.8%) represent the second main group of metal complexes. At the same time, the contribution of Cr(III) to the composition of anionic (40.4%) and neutral (40.8%) complexes was almost the same. The highest amount of metals was found in the fractions of humus substances with the molecular mass ≤2.0 kDa. The capability of various fractions of humus substances to bind Al(III), Fe(III), and Cu(II) was assessed.

SYBR Green I.
The method of intravital morphology of fish erythrocytes using vital stains has been developed. For the nuclei staining fluorochrome SYBR Green 1 was used. The photos of erythrocytes in thick drop were made; pictures were analyzed by the ImageJ 1.44p software. Obtained values of length of the large and small axes of nuclei and cells were averaged and compared with values, measured on the blood smears stained according to the Pappenheim method. Differences did not exceed 2%.
