damage
Under radionuclide contamination of aquatic ecosystems, hydrobionts of different taxa reveal responses induced by chronic external and internal irradiation. The definitions of such responses to irradiation as sensitivity, stimulation, and damage are given. The leveling of the concepts of radiosensitivity and radiation damage and the absence of integral comparative analysis of the development of closely interrelated reactions of biotic components of different hierarchical levels until recently remained an obstacle for further research and knowledge of super sophisticated and multistage processes of damage and restoration of irradiated biosystems.

In water bodies of urban territories, Turbellaria occur mainly in abundance. However, in performing hydrobiological studies they are rarely taken into account. The species richness and composition of Turbellaria were studied in 16 different ponds, lakes, springs, and reservoirs of the megalopolis. During the period of investigations (from 2013 until 2016), 56 species and 26 genera of the orders Catenulida, Macrostomida, Rhabdocoela, Proseriata, and Seriata were found in the studied water bodies. Among them, 28 species were unique to a certain water body, whereas 12 species were registered in 4-13 water bodies. A larger number of species was observed in water bodies with a higher variety of microbiotopes. The obtained results are indicative of a necessity of conservation of water bodies located within urban territories regardless of their types and size.

The data of zoo-drift dynamics in the Desna River mouth area over the low-water period are presented. The taxonomic composition, quantitative and behavioral characteristics of the current-carried animals depending on the changes of the flow velocities under the impact of the Kyiv HPP are considered. The differences in the strategy of passive and active migrations of planktonic and benthic invertebrates are analyzed.

biogeochemical cycling bacteria
Ecological integrity, that is spatial and seasonal variability of microalgae abundance and diversity, counts of biogeochemical cycle bacteria and carbon sequestration potential of microalgae, was studied in six waste stabilization ponds, used for treatment of the municipal waste waters and fish culture. The values of Shannon diversity index for Myxophycaeae, Euglenophyceae and Chrysophyceae were higher in facultative pond compared to maturation or fish ponds. The gross and net primary productivity of phytoplankton ranged respectively from 3.594 to 32.858 g C/m-2 · d-1 and 2.34 to 15.227 g C/m-2 · d-1. The P/R ratio in different ponds varied from 1.365 to 5.729. The nutrient cycling bacteria (heterotrophic, ammonifying, ammonia-oxidizing, cellulose decomposing and phosphate solubilizing) occurring in surface and bottom water layers tended to reduce in numbers from facultative to the last maturation or fish pond. The sum of total scores for different optimal conditions for fish growth also increased spatially exhibiting two clear cut zones: the facultative pond with dominance of blue green algae with greater carbon sequestration potential and the maturation or fish ponds developed a favourable environment for fish culture, mediated through microalgae-zooplankton grazing and microbial detritus food chain.

The peculiarities of the energy provision of different tissues of perch under the impact of elevated water temperature were investigated. It was established that the processes of energy generation and energy consumption under unfavorable temperature factor in muscles, gills and liver were characterized by different intensity. The dependence was shown of the course of energy exchange reactions, namely the adenylate metabolism, on the oscillating regime of water temperature. The data obtained indicate different degree of the energy supply of the tissues under atypical conditions.

Comparative characteristics of functioning of the main mechanisms of the energy generation (glycolysis and aerobic respiration) in the carp organism under the impact of copper ions (0.5, 2.0, 5.0 and 10.0 μ;g/dm3) and manganese ions (5, 20, 50 and 100 μ;g/dm3) was given on the basis of original and literature data. It was shown that adaptation to low concentration of copper (0.5 μ;g/dm3, equal to 0.5 MPC for fishery) and manganese (5, 20 and 50 μ;g/dm3, that is 0.5, 2 and 5 MPC) is supplied by the energy mainly by aerobic processes, and to high concentration of copper (2, 5 and 10 μ;g/dm3, that is 2, 5 and 10 MPC) and manganese (100 μ;g/dm3, that is 10 MPC) - by glycolysis.
