hydrotechnical construction
The paper deals with the history of the construction of the first hydropower complex in the Dnieper River - the Dniproges. Further the large-scale hydrotechnical construction in Ukraine became one of the priorities of its national economy, which was conditioned by intensive development of industry and agriculture. The construction of the cascade of six reservoirs in the Dnieper River was conditioned by natural deficiency of water resources. Conceptual approaches to the ecological assessment of the hydrotechnical construction impact on the water bodies were elaborated at the stage of design, construction and operation of each reservoir. This enabled to predict both favorable and adverse effects of the operation of these artificial water bodies. The significance of the Dnieper reservoirs and the ways of mitigation of the adverse effects of the large plain river transformation into the cascade of reservoirs are discussed. The future of the Dnieper reservoirs in view of specialists and mass media is discussed.

The state of various rivers of the Pripyat' and Teterev basins was assessed in terms of structural and functional indices of phytoplankton development: species, taxonomic, and information diversity, numbers, biomass, primary production, production-decomposition ratio, and saprobic index. Hydrophysical and hydrochemical characteristics were also studied. The obtained results can be used in monitoring river ecosystems using basin principle.

The many-year data on state of population of the relict copepod Limnocalanus macrurus Sars, 1863 in the Sita Lake (Belarus) were analyzed. Numbers of the copepod sharply decreased after water temperature in the upper water layer exceeded 26°C. Analysis of the vertical distribution of Limnocalanus showed that it avoids water layers with the oxygen deficit and elevated temperature. Growth of the surface temperature and decrease of the oxygen content in the hypolimnion resulted in reducing of the spatial niche and drastic decrease of the Limnocalanus numbers, and thus increased risk of its extinction. Similar mechanism of the numbers decrease and further extinction of the relict planktonic crustaceans probably acts in other lakes with similar morphometric and trophic characteristics.

The influence of Stratiotes aloides L. (Hydrocharitaceae) on the formation of microperiphyton communities was investigated. In the presence of S. aloides (for more than 33 days), the total number of algal species and the numbers of blue-green algae decreased. The influence of S. aloides on individual species of Bacillariophyta and Chlorophyta is species-specific. It does not depend on the affiliation of algal species to certain ecological groups.

In the cooling pond of the Berezovskaya Power Plant additional inoculation of shrimps Macrobrachium nipponense (De Haan) into the earth ponds in spring provided increase of their biomass more than trice in 100 days in polyculture with fishes. The specific numbers' growth rate over the season in the warm-water ponds amounted to 0.025-0.029 day-1. Size structure of shrimps' population in the ponds and off-take channel significantly differed. The productivity of M. nipponense in the warm-water earth pond of the temperate zone is comparable with productivity in the ponds in the natural habitats of this species — subtropics and tropics.

technogenic influence
In two various cooling ponds of nuclear power stations located within various catchment areas differing in their hydrographic characteristics and zooplankton composition, plankton invertebrates differed in their response to technogenic influence. In Koporskaya Bay of the Gulf of Finland, the discharge of heated waters of the Leningrad Nuclear Power Station resulted in the decrease in the quantitative indices of zooplankton. In the cooling pond of the Beloyarsk Nuclear Power Station on the Pyshma River, heated waters discharge resulted mainly in the increase in the numbers and biomass of plankton invertebrates. In both studied water bodies, heated waters discharge resulted in the decrease in the total number of zooplankton species. Pelagic species with a wide or worldwide distribution prevailed in terms of their numbers and biomass.

The content of ascorbic acid was determined in the liver, kidneys, gonads, spleen, and blood serum of Huso huso L., Acipenser gueldenstaedti Brandt, Acipenser stellatus Pall, and Acipenser ruthenus L. It has been found that ascorbic acid content varied depending on the sex, species, season, and habitat of fish. The concentration of ascorbat in the studied organs of fish of the family Acipenseridae increased in summer and decreased in wintertime. It has been shown that the content of ascorbic acid is organ-specific and depends on the functions of appropriate organs.

exopolysaccharides
Toxic effect of 4-tert-octylphenol and its biodegradation by microalgae of the genus Microcystis Kutz. ex Lemmerm. belonging to water bloom-forming organisms were investigated. It has been found that algae of the genus Microcystis belonging to various species and strains differ in their sensitivity to octylphenol. It has been shown that during the process of the studied microalgae cultivation the content of octylphenol decreases mainly as a result of abiotic processes (photolysis and hydrolysis) and biodegradation and, to a lesser extent, as a result of pollutant sorption by algal cells. It is likely that intensive synthesis of exopolysaccharides by the non-toxic strain Microcystis aeruginosa HPDP-6 can be one of the reasons of a low degree of octylphenol biodegradation.

Impact of phenol and potassium dichromate on several biochemical parameters of pikeperch was considered. These toxicants were shown to reduce Cortisol content in blood plasma and changes of the thyroid hormones content. It was shown that in the process of the short-term adaptation triiodthyronine is more significant than thyroxin. The considered toxicants also caused activation of lactate dehydrohenase, which contributes to the glycolytic process, and significant reducing of the energy resources (glycogen and lipids) in muscles and liver. Results of studies enabled to state high sensitivity of pikeperch to the toxic load.
