Paper deals with development of the river net of Ukraine in different geological periods. It was shown that there were historical preconditions for forming of the local combinations of the aquatic species, which arose in Pleistocene − Holocene due to belonging of the river systems to different ancient basins. Namely: Prypiat'−Dnieper combinations, peculiar for the Dnieper and Prypiat' Rivers and for the lower section of the Desna River; Ponto-Caspian−Dnieper combinations, peculiar for the middle and lower section of the Dniester River, the Dnieper River and its reservoirs, upper section of the Prut and Siret Rivers; Danube combinations, peculiar for the upper section of the Dniester River, the Latoritsa and Uzh Rivers; Upper-Tisa combinations, peculiar for the White and Black Tisa, Rika, Tereblia, Teresva, Kisva Rivers and their tributaries; and Pontic combinations, peculiar for the rivers of Crimea.

Lake Baikal.
As a result of long-term studies (2008−2013) of macroalgae of the littoral zone of the western bank of the southern part of Lake Baikal (the reaches of the Angara River − Listvennichny Bay), it has been found that species of the genus Spirogyra Link. dominate at the depths of 0.3−3.0 m in late summer and autumn. Previously species of this genus were not found in Lake Baikal. The study of the biology of the algae both under natural and under laboratory conditions made it possible to identify one of the dominant species as S. fluviatilis Hilse. Mass development of Stigeoclonium tenue (C. Agardh) Kutz. was registered for the first time in November 2012 near the water edge in Bolshiye Koty Bay. The intensity of development of the species of the genus Spirogyra was assessed in the region of investigations. It has been shown that during the period of mass development (November) the phytomass of the algae can attain 317 ± 143 g/m2. In this case, projective cover of bottom sediments represented by stones can be 100%.

Simultaneously measured concentrations of particulate organic phosphorus (PPIM), particulate organic carbon (CPIM) and chlorophyll in the 0−100 m water layer, obtained over the years 1985−1994 in the western and central parts of the Black Sea were generalized. According to these indicators and regression equations, calculated on the basis of them, a series of weighted averages of the PPIM concentration in the deep-water part of the sea throughout the year was restored. On the basis of the calculated weighted average PPOM concentrations and rate of its sedimentation, within-year variability of sediment PPOM flux from the photosynthesis zone was estimated. Its maximal values corresponded to the cold, minimal − to the warm period of the year. Average annual values of PPOM flux, obtained on the basis of average monthly weighted mean of its concentrations, and calculated on the basis of the long-term average monthly values of the «new» primary production were practically identical and amounted to 46 and 44.9 mg-at P·m−2·year−1 respectively.

Data on the accumulation and influence of selenium compounds on the vital activity of marine and freshwater algae are analyzed in the paper. Results of the study are indicative of a possibility of accumulation of large amounts of selenium (≤ 1000 times higher than its content in the aquatic environment) by microalgae. This element was registered in the composition of intracellular metabolites and high molecular compounds, primarily − amino acids, mono-, amino-, and polysaccharides, cytosol proteins and cell membranes, some fatty acids, and lipids. The process of accumulation is considered as the mechanism of detoxification and adaptation to a rather high content of selenium in the environment, and also as a way of selenium storage in algal cells.

The distribution of proteinase activity in various glandular structures of the digestive system of the veined whelk Rapana venosa was investigated. Maximal proteolytic activity and variety of molecular forms of enzymes were registered in the salivary glands, and minimal proteolytic activity was registered in hepatopancreas and the Leiblein gland. Using specific inhibitors it was established that the proteolytic activity of the salivary glands was caused mainly by metalloproteinases.

The paper deals with analysis of morpho-physiological and biochemical indices of perch, pike-perch and ruff from different habitats in winter. Relation between oxygen regime of the water body and content of lipids and glycogen in the tissues was established. On the basis of physiological and biochemical parameters it was shown that among the considered habitats the most favorable for wintering were the mouth area of the Teteriv River, Sobache Gyrlo bay and ponds of Pushcha Voditsa green zone. According to the spleen index and macroergic substances content pike perch was shown to be the most sensitive to unfavorable impact of environmental factors.

Dynamics of the formation of irradiation dose in fish after single influx of 90Sr and 137Cs into a water body were studied by the method of mathematical simulation. The dose rate of fish irradiation formed by 90Sr depends on its content in the organism, whereas that of 137Cs − on the concentration of this radionuclide in the water, bottom sediments, and fish organism. Under given conditions, the dose rate of fish irradiation formed by 90Sr will increase for 33 months. Its maximal values will be registered almost throughout the year. After 10 years, the dose rate of fish irradiation will be 2.4 times lower than its maximal value. The dose rate offish irradiation formed by 137Cs will increase for 4−5 months. After two years, the rate of the integral dose will be 8.2 times lower than its maximal value.
