microstructure
The peculiarities of growth and development of water fern Salvinia natans (L.) All., the surface microstructure of vegetative and reproductive organs was studied using the scanning electron microscopy. Its existence at the water and air interface is ensured by the specific microstructure of floating fronds. Abaxial surface of floating and submerged fronds has thin cell walls of the epidermis and numerous filamentary outgrowths in epidermal cells. Sporocarp membrane structure contributes to the annual summer-green phenorhythm, promotes mega-and microsporangia submerging to the bottom in autumn and their rising to the water surface in spring.

The allelic polymorphism and specificity of the allele distribution and their frequencies were studied by microsatellite DNA loci (Psp12, Psp21, Psp26, Psp28) in the three paddlefish stocks. The most polymorphic locus was Psp26, the average number of alleles per locus was 7.6. The presence of common allelic variants in the studied loci indicates the common origins of paddlefish stocks cultivated in Ukrainian fish farms. The presence of different alleles by microsatellite DNA markers indicates the probable effect of the conditions of cultivation and the geographical location of fish farms on the specificity of the alleles distribution.

Water quality in the Uday River within the territory of the Pyryatyn National Natural Park was assessed based on results of long-term investigations of macrozoobenthos structural characteristics. It has been found that indicators of eutrophic waters (in terms of their numbers) and α-oligosaprobic organisms prevailed at many stations. The waters located downstream of the town of Pyryatyn proved to be most contaminated. They were assessed as polytrophic and β-mesosaprobic.

Relationship between the processes of photosynthesis and organic matter decomposition was assessed in water bodies of the Aleksandriya Dendrological Park (the town of Belaya Tserkov, Ukraine), many of which are subjected to anthropogenic load. It has been shown that the range of fluctuations in production characteristics of phytoplankton of the studied ponds was determined mainly by different content of inorganic compounds of nitrogen and phosphorus in the water. A predominance of decomposition (R) overproduction (A), and also an approximation of A/R ratio to 1, registered in many studied ponds are indicative of a high intensity of the process of self-purification. A predominance of production over decomposition observed in the ponds of the Eastern ravine is indicative of the decrease in the intensity of self-purification potential.

ecological plasticity
The peculiarities of adaptive response of various fish species to the influence of anthropogenic load are discussed in the paper. Under unfavorable conditions, the activity of lactate dehydrogenase in the gills and muscles of many fish species increased, whereas the activity of succinate dehydrogenase decreased. It has been found that in a set of biochemical indices Alburnus alburnus (L.) is characterized by the highest ecological plasticity. The obtained results can be used in performing biomonitoring of water bodies and in determining sensitive and tolerant species.

Results of comparative analysis of the content of immune complexes and lipids and of the oxidative processes in the muscle tissues of Rapana venosa occurring in various sections of the coastal zone of the Caucasus coast of the Black Sea differing in the degree of anthropogenic load are given in the paper. It has been found that the specimens caught in the sections subjected to intensive anthropogenic load were characterized by a rather high content of the products of lipid peroxidation and immune complexes and by a low antioxidant activity.

The features of crucian carp adaptation to pollution by ammonium nitrogen over different time intervals were studied. The fish responses were judged by changes of activity of lactate dehydrogenase, succinate dehydrogenase, Na+/K+-adenosine triphosphatase, NADP-dependent glutamate dehydrogenase, alanine and aspartate aminotransferases. The long-term (over some generations) adaptation resulted in activation of the energy metabolism enzymes in muscles, liver and gills. Activity of alanine and aspartate aminotransferase was registered in liver of specimens of all experimental groups.

The article presents chamber models of radionuclides 90Sr and 137Cs content dynamics in abiotic and biotic components of the Gluboke and Daleke lakes of the Chornobyl exclusion zone. The forecast was made for the transition of the considered radionuclides from the catching area to water and bottom sediments, their accumulation by the reed biomass over 20 years since 2000. Two periods of the radionuclides' redistribution were stated - period of intensive changes and period of dynamic equilibrium. It has been established that 137Cs is accumulated by the reed tissues more intensively than 90Sr. Over short period of the dynamic equilibrium almost half content of 90Sr and 137Cs is accumulated, which could transit to the reed biomass over 20 years.

137Cs specific activity in higher aquatic plants and fish in water bodies differing in their types and trophic status and located within the territory of Ukraine was investigated in 2012-2017. In plants occurring in water bodies located within the Chernobyl exclusion zone, 137Cs specific activity accounted for 69,000 Bq/kg of plant air-dry mass, in fish it was 30,000 Bq/kg of natural humidity. In higher aquatic plants and fish found in water bodies located outside the Chernobyl exclusion zone, 137Cs specific activity accounted for 10,000 and 1,000 Bq/kg, respectively. In the above-ground organs of Phragmites australis and Topha angustifolia, the content of 137Cs was closely similar to that in their rhizomes, whereas in the soil roots it was almost 10 times higher than that in the above-ground organs and rhizomes.
The degree of 137Cs accumulation by higher aquatic plants and fish depends not only on the density of radionuclide contamination of catchment area, but also on the rate of water exchange and trophic status of a water body.
Outside the Chernobyl exclusion zone, the content of 137Cs in fish of the closed lakes located in the northern part of the Rovno and Kiev regions was higher than its limiting permissible concentration.
