Necessity is substantiated of the multilateral and purposeful assessment of the aquatic ecosystems status by means of characteristics of their structural and functional organization, including biota and biotopes, mainly by diversity indexes, mechanisms of water quality and cenosis productivity formation. Suggested concept of the aquatic ecosystems' status assessment is based on material of the long-term studies of the technogenically modified and protected surface water bodies of Ukraine.

Results of the study of zooplankton communities of the cooling pond of the Khmelnitskiy NPS carried out in 2005−2006 after putting into operation of the second energetic unit and after Dreissena polymorpha Pallas introduction are given in the paper. Changes in the composition, distribution, and abundance of zooplankton occurring in different seasons, and also its spatial distribution and quantitative indices of Dreissena veligers development, were studied. It has been known that Dreissena veligers are the source of biological hindrances.

succession
Results of the study of the succession state of plankton communities of the regulated and river sections of the Teterev River in terms of their production indices are given in the paper. It has been found that autotrophic direction of metabolism of plankton communities, which coincides with the spring, summer, and autumn peaks of primary production, prevails in the seasonal cycle. A predominance of decomposition over production is observed during the period of seasonal depression, and also in early spring and late autumn. It has been shown that earlier stages of succession of plankton communities prevail in the Promyshlennoye reservoir, whereas later stages of succession of plankton communities ("balanced" communities) are observed in the river section.

river
High heterogeneity and biodiversity of genetic profiles of four groups of bacteria in bacterioplankton of the ponds contaminated by mineral nitrogen, and also in the section of the Ros River near the Belaya Tserkov Experimental Hydrobiological Station of the Institute of Hydrobiology of the National Academy of Sciences of Ukraine (the town of Belaya Tserkov), were revealed using the PCR-DGGE techniques. The groups Cytophaga-Flavobacterium (51) and β-Proteobacteria (50) were characterized by the largest number of rDNA sequences. A high contribution of sequences (especially in the β-Proteobacteria group) common to bacterioplankton of all the studied water bodies is indicative of a high plasticity of their metabolism, and also of their capability to adapt to various conditions of their occurrence and to the content of mineral nitrogen in the water of 0.29−1349.0 mg N/L.

seasonal dynamics
Seasonal dynamics of the process of sulfate reduction in water bodies differing in their geographic situation, trophic level, pH, Eh, water salinity, sulfate content, temperature regime, and other factors were investigated. It has been found that in various lakes the maximum rate of bacterial reduction of sulfate was registered mainly in summertime.

Various species of Cyanophyta differ in their response to the influence of the same exogenous biologically active substances. Plankton species of blue-green algae characterized by the maximum specific surface of their cells are most sensitive to the influence of these substances. A decrease in the specific surface of algae cells is accompanied by the decrease in the amount of biologically active substances capable of entering their cells and capable of inhibiting their functional activity.

Lipid and lipoprotein composition of the blood serum of three Antarctic fish species: Notothenia coriiceps, Trematomus bernacchii and Chaenocephalus aceratus has been investigated. Differences of total lipids and phospholipids content, as well as individual phospholipids and lipoproteins redistribution in the blood serum were revealed. Obtained results showed, that revealed peculiarities can stipulate energy and metabolic processes behavior, connected with adaptation to the Arctic conditions.

The toxic effect of high NH+4 concentrations (1, 5, 25 mg N/dm3) on physiological parameters of carp was investigated. It was stated that under the effect of these concentrations liver and kidney indexes practically did not change, spleen index increased. Total hemoglobin and its not-functional form methemoglobin concentration in carp's blood increased. Under the chronic impact of ammonia nitrogen its content in fish muscular tissue was relatively low.

forms of metals migration
Results of experimental simulation of the influence of pH on the migration of metals (Mn, Cr, Zn, Pb, and Mo) in the "bottom sediments - water" system are discussed in the paper. The values of pH of the natural water accounted for 8.3, 7.0, and 6.0. In the experimental systems with pH of the water of 7.0 and 6.0 after three days of exposure, the concentration of dissolved oxygen decreased to 0. As a consequence, manganese migrated from the bottom. Its concentration in the water was 3.0 mg/L. The influx of other studied metals was also observed. They income both in the form of free ions and in the form of organic complexes. At pH 8.3, they income mainly in the form of organic complexes (60−80%). A decrease in pH was accompanied by the increase in the intensity of metals migration mainly at the expense of free ions (70−75%). The lowest intensity of migration from bottom sediments into the water was typical to lead and molybdenum, which was conditioned by their low content in bottom sediments, and also by the peculiarities of their distribution among their different fractions.

Results of hydrological and hydrochemical monitoring carried out from July 2004 until June 2007 in the vicinity of the experimental industrial mussel farm located near the exit from Sevastopol Bay are given in the paper. Accumulation of nitrogen and phosphorus bearing organic and mineral compounds, a decrease in the value of pH, the increase in the value of BOD5, and also deterioration in the processes of production and decomposition, conditioned by the vital activity of mollusks were not revealed as a result of the performed monitoring. This fact suggests that the products of mussel metabolism income into the open sea.
