The paper is dealt with the study of the structural and functional organization of phytoepiphyton of the reservoirs of the Dnieper cascade. The influence of some hydrophysical factors, including water temperature and its transparency, on phytoepiphyton was assessed. It has been found that phytoepiphyton of the Dnieper reservoirs is highly diverse in its taxonomic composition, whereas its qualitative and quantitative indices vary over a wide range, which depends, to a large extent, on the influence of ecological factors.

Paper presents results of investigation of sedimentation activity of Viviparus viviparus (Linné, 1758) in the Vidsichne reservoir in the Teteriv River (Ukraine). Dependence of sedimentation rate on mollusks' age and mass and sexual differences of sedimentation activity were stated. Impact of several abiotic factors (suspension amount, temperature) on sedimentation activity of V. viviparus was analyzed.

Morphometric and cytogenetic homeostasis of fishes in small rivers of the Volyn' Polissya has been evaluated. Functional dependence of morphometric and cytogenetic homeostasis in river sections with different quality of the aquatic environment was stated. Local scale for integral assessment of anthropogenic load on hydroecosystem was suggested.

Paper deals with dynamics of catches, age structure and size-mass characteristics of the main commercial fish species of the Dniester liman - gibel carp Carassius gibelio (Bloch, 1782) and bream Abramis brama (Linnaeus, 1758). Age structure of gibel carp and bream populations turned to domination of younger groups owing to intensive commercial catches. Estimated parameters of the Bertalanffy equation, coefficients of total, natural and fishery mortality are presented. Stocks of gibel carp and bream were assessed. The stock of gibel carp in the Dniester liman is about 1150 tons, of bream – about 630 tons.

Dynamics of the content of photosynthetic pigments, including chlorophyll a and carotenoids, in the unit volume of phytoplankton biomass in the surface layer of water of the littoral zone of Obolon Bay of the Kanev Reservoir were
studied in summer 2014−2015. The main water bloom forming species of Cyanoprokaryota represented by Anabaena flos-aquae Bréb., Microcystis aeruginosa (Kütz.) Kütz., and Aphanizomenon flos-aquae (L.) Ralfs dominated in phytoplankton in terms of their biomass. The specific content of chlorophyll a in phytoplankton biomass (Chl. a/B) depended inversely on water temperature. The increase in the temperature of water from 21 to 31°C resulted in the decrease in Chl. a/B ratio by a factor of two. At extremely high temperatures of water, the total content of carotenoids in the unit volume of phytoplankton biomass also decreased. Relationship between chlorophyll a content and water temperature is described by linear function, whereas relationship between the total content of carotenoids and water temperature – by polynomial function.

Dynamics of chlorophylls content in the submerged macrophytes Najas guadalupensis, Ceratophyllum demersum and Myriophyllum spicatum under elevated concentration of phosphorus in the model aquatic medium was studied. It has been found that in chronic experiments (14 days) content of chlorophylls in N. guadalupensis decreased under lesser concentration of phosphorus (starting from 1 mg P/dm3) as compared with C. demersum (starting from 5 mg P/dm3) and M. spicatum (10 mg P/dm3). Species specificity of phosphorus absorption by the plants depending on its concentration in water has been revealed.

The paper is dealt with the study of the influence of the ions of heavy metals (Cd2+, Zn2+, Cr3+, Cr2O72-, Mn2+, Ni2+, Cu2+, and Pb2+) on the content of Β-carotene in the haemolymph, hepatopancreas, mantle, and leg of Lymnaea stagnalis. The studied concentration of the ions of heavy metals accounted for 0.5 of their limiting permissible concentration. Relationship was established between the content of the studied pigment and duration of exposure (2, 7, 14, and 21 days). It has been shown that in the organism of L. stagnalis the content of Β-carotene depends on the type of tissues or organs. It has been found that in the organs and tissues of L. stagnalis the influence of the studied ions on the content of Β-carotene is diversified. On the one hand, they are toxic, whereas, on the other hand, they are involved in the processes of regulation.

Impact of herbicide Consultant in form of suspension concentrate (SC) (active ingredient – nicosulfuron 40 g/l) on growth and reproduction of Ceriodaphnia affinis was studied in chronic experiments. Under concentration of 0.5 mg a.i./l reproduction stopped in II generation. Under 0.25 mg a.i./l statistically confident reducing of fertility was equal to 59%, under 0.1 - 40%, under 0.1 - 0.001 - 23.4 - 17.3%. Concentration 0.0001 mg a.i./l was ineffective for Ceriodaphnia affinis. Herbicide showed embryotoxic effect. High toxicity of low herbicide concentrations to crustaceans is supposed to be caused by preparation composition.

Results of comprehensive studies on abiotic and biotic components of the ecosystems of the Denishi and Otsechnoye reservoirs of the Teterev River are given in the paper. The main attention was paid to the study of pH, dissolved
oxygen concentration, suspended matter content, and water coloration, and also to the study of the peculiarities of migration and distribution of such chemical elements as Si, Al, Fe, Ti, and Cu. The structure (taxonomic diversity, numbers,
and biomass) and ecological and geographic characteristics of phytoplankton were also investigated. Relationship was established between phytoplankton development and pH, O2, and Si. Results of the study of the content and forms of metals occurrence suggest that the environmental conditions in the Teterev River are favorable to the development and vital activity of phytoplankton.

Ya. I. Starobogatov's concept regarding phased settling of the continental waters by primary aquatic invertebrates explains differences in fauna of water bodies of different types, in species number in genera and families and in geographical distribution of these animals. Descendants of later settled species are more sensitive to the water quality and anthropogenic pollution than descendants of earlier settled species. Therefore they are more important as indicators of water quality.
