ecological state
Changes in water quality, ecological state, and biodiversity as a result of the volley of sewage were assessed based on results of the performed hydrochemical and hydrobiological investigations of the Khomora River and of the sections of
the Sluch' River located upstream and downstream of the estuary of the Khomora River.

homeostasis
The paper is dealt with a possibility of applying the concept "homeostasis" in studies of epiphytic algae communities in the Dnieper reservoirs. It has been shown that in polydominant communities of epiphytic algae with a high species
richness fluctuations in the total biomass are "smoothed out", which makes it possible to maintain homeostasis.

trophic status
The approach was developed to assess provision of primary production (phytoplankton) by nitrates in the small lakes. By example of a series of lakes of different trophic status the ratio was calculated between primary production,
measured by traditional method of dark and light bottles, and production, obtained by conversion of nitrate concentration in water by Redfield stoichiometry, "nitrate production". It was supposed that three types of this ratio
(below 1, equal to 1, above 1) indicate character of the producers' limitation in the ecosystem. It was revealed that within the same trophic type there are water bodies differently using their production potential depending on the nutrient load and, presumably, on the tension of phyto- and bacterioplankton relationship in their ecosystems.

The article deals with the mass development and morphological features of autotrophic dinoflagellate Palatinus apiculatus (Ehrenberg) Craveiro et al.
(Dinoflagellata, Dinophyta) in the Verbne Lake (Obolonskiy district, Kiev). It was found that the cells of this population were characterized by larger size than
given in literature data for other localities. The following peculiarities of the cell structure were revealed: relatively small size of 1 plate and its distance from the
apex; slight displacement of the cingulum (0.5 its width); curvature of the sulcus, more pronounced ornamentation of pre-cingular, post-cingular and antapical plates. Non-conformity of some P. apiculatus illustrations published by E. Lemmermann (1900) and R. Thompson (1950), which have been used earlier in determinative keys was concluded. For the correct identification of P. apiculatus we recommended drawings by M. Lefevre (1932), photos from recent publications (Hansen & Flaim, 2007; Craveiro et al, 2009), as well as original photographs and drawings.

The first data on ichthyoplankton of the Koturka River (a regulated small river of the Dnipro catchment) were obtained. It was found that the most portion of the fishes' larvae settle the littoral zone of the river ponds. At the same time, some species are distributed in the pelagic zone and might be transported to the downstream ponds by drift. The ichthyoplankton structure was dynamic and changed over the season: the larvae of early spawning species (perch and roach) appeared firstly, then they were substituted by the later spawning species (bitterling and sunbleak).

Results of the study of zoobenthos and zooperiphyton of the cooling pond of the Chernobyl NPS carried out in 2012–2013 prior to its removal from service are given in the paper. In 2012–2013, the composition and quantitative indices of
contour communities were rather stable. The cenotic structure of the studied communities remained almost unchanged: zoobenthos communities occurred at the depths of 3 and 5 m, whereas zooperiphyton communities were observed on stones of the stream directing dam.

The biochemical composition of the biomass of some green algae of the families Scenedesmaceae, Selenastraceae, and Hydrodictyaceae was analyzed and compared. It has been found that under different conditions the cells of these
algae contain 10–60% of proteins, 8–38% of carbohydrates, and 5–49% of lipids. Representatives of the family Scenedesmaceae were characterized by a higher
content of proteins, whereas representatives of the family Selenastraceae – by a higher content of carbohydrates and lipids. It has been shown that biochemical indices are species-specific and vary over a wide range.

The review deals with data on the chemical properties of parabens, main paths of their entering into the water bodies and transformation in hydroecosystems. Besides, hydrochemical methods of parabens detecting in the aquatic environment, their effects on the aquatic organisms of different trophic
levels, as well as ability to accumulate in the organisms are presented.
