The conceptual approaches of V.I. Vernadsky concerning the role of the hydrosphere in biospheric processes are considered. The significance of the Earth water cover in forming the living matter as a geological factor is analyzed. The knowledge of mechanisms of functioning of aquatic ecosystems in a context of the integral biosphere concept is emphasized as an important task of the hydroecological science.

The species composition of the main communities, including phyto- and zooplankton, microfauna, zoobenthos, fish fauna, and fish parasites, of the upper reaches of the Tisa river within the territory of Ukraine was investigated. It has been found that the number of species of the hydrofauna essentially decreased as compared to that registered in recent decades, which was conditioned by changes in the water regime of the river as a result of excessive timber purchasing in the Ukrainian Carpathians.

Essential distinctions were revealed in comparing phytoperiphyton with other ecological groups of algae communities occurring in the Dnieper reservoirs. It has been found that algae inhabiting solid inorganic substrata significantly differ from phytoplankton, phytobenthos, and phytoepiphyton in their species composition, floristic spectra, number of species, complex of dominant species, spectra of leading genera, and also in the intensity of their development. Phytoperiphyton represents a specified well-defined ecological group of algae communities.

Specified concentrations of phenol carbonic acids released by higher aquatic plants into the water are capable of inhibiting the physiological activity of Cyanobacteria. At the same time, they are capable of stimulating the development of Chlorophyta, Bacillariophyta, and also of algae belonging to other taxonomic groups. The highest concentration of phenol carbonic acids is registered in the sections of the reservoirs occupied of the thickets of higher aquatic plants. In the sections characterized by mass development of water bloom forming species of Cyanobacteria, the concentration of these acids is rather low.

The peculiarities of accumulation of the ions of heavy metals, including Cd, Zn, Cu, Pb, and Zn, in the organism of Bivalvia were determined. The distribution of these elements over the tissues and organs of mollusks was studied. Concentration factors, and also the coefficients of bottom biological accumulation, were calculated. The obtained results were processed using the correlation analysis.

General content and fractional composition of carp serum blood proteins under the influence of heavy metals (zinc, manganese, lead, and copper) in their 2 and 5 MPC concentrations were studied. Copper and lead exert the most considerable effects on proteins of carp blood. Concentrations of general protein in carp serum depend on toxicity of metal, its concentration, and a season of the year. The lowering of the level of albumins under the influence of the studied metals was noted. The seasonal dependence of the content of a-globulins liable to intoxication by heavy metals in the studied concentrations was revealed. The changes in contents of b- and g-globulins showed no clear dependence on a season of the year, and were connected only with specific character of the metal acted.

Accumulation of the ions of heavy metals (on the example of Cu2+ and Mn2+) by higher aquatic plants, including Najas guadelupensis L. and Ceratophyllum demersum L., as well as by green filamentous algae, including Cladophora glomerata (L.) Kutz. and Oedogonium cardiacum (Hass.) Wittr, was studied with the purpose of determining the most promising monitor species. It has been found that hydrophytes are capable of accumulating large amounts of copper and manganese. In terms of their capability for accumulating metals, the studied plants may be arranged in the following order: Cladophora glomerata > Oedogonium cardiacum > Najas guadelupensis > Ceratophyllum demersum. The obtained data suggest that higher aquatic plants are characterized by more advanced mechanisms of metabolic control of the content of heavy metals as compared to filamentous algae. It is advantageous to use filamentous algae for monitoring the degree of contamination of the aquatic environment by the ions of heavy metals, in particular by Cu2+ and Mn2+.

There were for the first time analyzed the problems of seasonal and age dynamics of invasion of two Baikal endemic species, Baikal oilfishes (golomankas, or golomyankas), with cestodes of the genus Proteocephalus. In particular, it has been shown that golomankas play the role of reservoir hosts for Proteocephalus exiguus parasitizing on omul (Arctic cisco) and whitefish. Principal peculiarities of infestation and regional distribution of invasion are considered.

The data concerning epizootology of the tumor disease in Esox lucius L. in the Kiev Reservoir in the years 2000-2001 are provided. No clear seasonal regularities in distribution of neoplasms over the reservoir were noted, whereas the age features of the disease occurrence can be revealed. Three stages in development of tumors and pathological processes are distinguished.

The concentration of metals, including Fe, Sr, Mn, Cs, Zn, Ni, Cu, Cr, Pb, Co, and Cd, was determined in the water of Kakhovka reservoir, in the water of the cooling pond of the Zaporozhye Nuclear Power Station, and also in higher aquatic plants. The concentration factors of these metals were calculated. It has been found that a high temperature of water influences the capability of higher aquatic plants to accumulate metals.

It was investigated the possibility of using a variable component of chlorophyll a fluorescence that was registered at the action of inhibitors for studying primary phytoplankton production under conditions of a wide variation of light intensity within the PAR limits. There were implicated simultaneous measurements of phytoplankton primary production, variable fluorescence and chlorophyll a concentration in water bodies and under low light conditions in the experimental microecosystems.

In the Dnieper reservoirs, the concentration of phenol compounds ranged from 180 to 1850 μ;g/L. The content of these substances in the Dnieper reservoirs depended on their concentration in adjacent water bodies, on the area of shallow-water sections occupied by the thickets of higher aquatic plants, and also on the intensity of development of phytoplankton. The total content of phenol compounds dissolved in the water gradually decreased with distance from the near-dam section of the Kiev reservoir in a south-ward direction. In the Kiev reservoir, the total content of phenol compounds accounted for 551 μ;g/L, whereas in the Kakhovka reservoir it was 212 μ;g/L.
