classification of hypoxic states
Data are comprehended on the mechanisms of hypoxic states development in the primary-aquatic organisms. The ways of modification of actual classification of hypoxic states were proposed on the base of primary and secondary hypoxia conceptions. New types of exogenous, hemic, locomotor and diffusion hypoxia, character mainly for the aquatic organisms, are considered.

macroinvertebrates
lower reaches of the Danube River
A more refined list of macroinvertebrate species of the relict Ponto-Caspian complex of the lower reaches of the Danube River within the territory of Ukraine is given in the paper. Ecological characteristics of some representatives of this group, and also long-term changes in the structure of invertebrate complex occurring in this region, are discussed.

The structure of macrobenthos, quantitative indices of its development, and main communities were described in the crenale and rithrale of the Novoselka River (the Sakhalin Island). The influence of the speed of water flow, type of bottom sediments, and lithodynamic regime on macrobenthos was investigated.

river estuary
organotrophic bacteria
CO2 heterotrophic assimilation
fluorescence in situ hybridization
The structure of microbial communities was studied in the zone of emptying the Upper Angara River into Lake Baikal in 2006−2008. During the whole period of investigations, the maximum values of the total numbers of microorganisms and of the numbers of organotrophic bacteria were observed in the estuary of the river and at the distance of 3 km from it − 3.0 ± 0.1−7.5 ± 0.8 million cells/ml and 2100 CFU/ml, respectively. The peak of CO2 heterotrophic assimilation by bacteria (1.3 μ;g C/l·day) was also registered in this area. Correlation (r = 0.87) was established between the spatial distribution of microbiological parameters and water temperature. Changes in phylogenetic structure of microbial communities were revealed using the method of fluorescence in situ hybridization (FISH). Representatives of the phylogenetic groups Alphaproteobacteria, Actinobacteria, and Cytophaga-Flavobacteria dominated in the estuary of the river. Betaproteobacteria dominated at the distance of 3 km from it, whereas the contribution of Gammaproteobacteria and Planctomyces increased in the pelagic zone of the lake.

humus substances
fulvic acids
phytoplankton
The response of plankton algae occurring in water bodies of various types to the influence of fulvic acids isolated from the water of the Kanev Reservoir (Ukraine) was investigated. The concentration of the studied substances introduced into the samples of the natural water accounted for 30.0 and 80.0 mg/L. The response of phytoplankton to the influence of fulvic acids was judged from changes in its numbers and biomass. Representatives of Cyanophyta, Chlorophyta, Euglenophyta, Bacillariophyta, and Dinophyta differed in their response to the influence of the studied organic substances.

lipids
proteins
Paper deals with changes of the qualitative and quantitative composition of the aquatic plants' membranes under the effect of zinc and lead ions and diesel fuel. Mechanism is described of the aquatic plants' adaptation to the toxic substances due to forming of the secondary concentric membranes and changes of the lipid and protein composition in course of their forming.

self-purification processes interrelation
Paper deals with simulation of dynamics of biological purification of the water systems. Characteristic is given of the author's model of the water quality parameters dynamics, developed on the basis of ordering of groups of hydrobiological and physico-chemical self-purification processes with account of their successful and simultaneous interrelation. Model is generalized with account of assumptions, proposed by V. I. Lavrik at development of similar model of biological purification of the waste waters in reactor [2−5]. This enables adequate formulation of more number of processes, occurring in the water systems after the waste waters income.
