biocenotic relations
system approach
Paper deals with analysis of existent views on the concept of consortium and its place in ecological researches. The issue of classification of biocenotic relations in ecosystems is discussed. Examples of consortia and consortium-type communities of different level, and their graphic models are proposed. Ecological conceptions of "ecological engineers" and "keystone species" are discussed. The necessity is argued of development of the biocenotic approach to investigation of hydroecosystems with such significant elements as consortia.

The species composition of macrozoobenthos and the quantitative indices of its development were studied in the rivers of the Danube and Dniester rivers basins within the territory of the Carpathians region. The biotopes suitable for the development and reproduction of brook trout in the studied rivers were revealed. The numbers of brook trout fry necessary to the reproduction of its natural populations were calculated on the basis of the obtained data. It was recommended to introduce annually 805 thousand specimens of brook trout fry with the body mass of the specimens of not less than 10 g.

At cultivation of Chlorella vulgaris Beijer. culture (strains LARG-3, HPDP-120) in close system at medium saturation by CO2 it was stated that at
initial stages extra carbon dioxide negatively affected functional activity and caused changes of morphological characteristics of the alga. However this phenomenon vanished in course of adaptation to the given conditions, it was reversible at reduction of the CO2 content in the system.

adenylate energy charge
phosphorylation potential
Influence of anoxia on the energy status of tissues of bivalve mollusk Anadara inaequivalvis Br. has been studied in experiment. Anoxia caused decrease of the adenylic nucleotides pool and energy potential of the tissues on the whole. This was expressed as decrease of the ATP and ADP fractions content; decrease of the adenylate energy charge (AEC) and phosphorylation potential (PhP). In 3 days of the experimental anoxia decrease of all studied parameters’ values did not exceed 40−45%. It allows to assume observed
changes of adenylate system state to have balanced character and to be
functionally sufficient to maintain subbasal rate of metabolism.

crucian carp Carassius auratus
acclimation
protein spectra
Paper deals with SDS-electrophoresis of proteins of the crucian carp Carassius auratus, taken in winter, spring and summer and kept at different temperature. It was stated that after keeping "winter" fish at 5°C for 2 weeks content of 205 kDa protein significantly decreased in red muscles and myocardium; and content of 172 kDa protein decreased in liver. In white muscles of the deacclimated fish decreased content of 105 and 15 kDa proteins. Protein
composition of tissues of the "summer" and "winter" animals almost did not differ. Protein spectra of the crucian carp tissues depends not only on temperature, but on season as well, because in the "spring" fish, in spite of low water temperature, only in red muscles 205 kDa protein was found, peculiar for "winter" fish. Protein spectra of myocardium and liver did not differ from those of the "summer" fish. Cold acclimation for 2 weeks in summer season did not
effect protein composition of skeletal muscle, myocardium and liver tissues.

Dynamics of 90Sr, 137Cs, and transuranium elements accumulation in freshwater Bivalvia of the exclusion zone of the Chernobyl NPS were analyzed
in 1995−2008. Results of the assessment of dose loads, frequency of chromosome aberrations, and hemolymph composition in Lymnaea stagnalis are presented. The capacity of the absorbed dose was registered within the range from 0.3 to 85.0 μ;Gr/hour. A rather high frequency of chromosome aberrations (to 27%) in the tissues of embryos, as well as changes in hematological indices in
the adult specimens of mollusks, was registered in the closed water bodies.

ecological-hydrodynamic regionalization
water-exchange characteristics
The ecological and hydrodynamic regionalization of the Dnieper cascade reservoirs has been proposed, based on differences of genesis and dynamic characteristics of water masses in transit and not-transit zones. Intensity of water exchange in transit and not-transit zones of each Dnieper reservoir has been assessed. It is supposed that the intensity evaluation of water exchange processes can serve as a key to quantitative assessment of biotic balance and energy fluxes in the reservoirs' ecosystems.
