macroinvertebrates.
The distribution of the macrofauna of invertebrates of the marine edge and fore-delta of the Kiliya branch of the Danube River delta has been analyzed on the basis of long-term investigations. The structure of invertebrate complexes was studied in the sections differing in their biotopes, and also in their hydrochemical and hydrological regime.

The frequency of occurrence, size-mass parameters and phenotypic belonging of mussels Mytilus galloprovincialis (Lamarck, 1819) with partial albinism (non-pigmented mantle and podium) in the bottom communities and periphyton settlements near the Odessa bay (the Lanzheron Cape, north-western section of the Black Sea), were studied. Individual morphometric characteristics were compared of albino-forms and normally colored specimens. No statistically significant differences of mass characteristics of the shells, wet and dry mass of the soft body between non-pigmented and normally colored specimens of the same size group were found.

Literature and original data regarding diversity of the planktonic algae of the Sloviyans'k saline lakes were comprehended. Phytoplankton comprised 334 species (352 intra-species taxa) of nine departments. Maximal average numbers was registered in the Gariache Lake, and minimal − in the Ripne Lake. Maximal average biomass was registered in the Slipne Lake. Seasonal dynamics of numbers and biomass and dominant complexes were determined.

A review of available literature data dealt with the study of phytoplankton of techno-ecosystems of nuclear and thermal power stations is given in the paper. Data on the taxonomic richness of phytoplankton and its abundance in cooling ponds of thermal and nuclear power stations are discussed. The problem of bio-hindrances conditioned by the development of phytoplankton is considered. Data on invasive species are also discussed.

Results are presented of study of lipid composition in liver of the most common freshwater fishes of small rivers of the Western Podillya − carp, crucian carp, perch and pike. Interspecies differences in lipid content and ratio of lipid classes in liver cells of fish taken from various small rivers were studied. The changes of fractional composition of lipids as a response to the effect of environmental factors, useful for biomonitoring of the aquatic ecosystems, were considered.

enzymatic activity
Connection has been revealed between total protein content, succinate dehydrogenase (SDH) activity in hepatopancreas and intensity of Trematoda infestation in mollusks under different temperature. Intensification of infestation was shown to cause decrease of total protein content (by 11.67−36.01%) and increase of SDH activity (by 17.72−77.21%) as compared with control. As water temperature increased from 21 to 30°C total protein content in hepatopancreas of infested mollusks also increased, its maximal value was registered at 26°C. SDH activity in hepatopancreas of highly infested mollusks decreased as temperature increased from 21 to 30°C.

On the basis of comprehension of original and literature data sedimentation regime of the Kyiv reservoir has been considered. Actual state of the bottom sediments has been analyzed and sediments' balance has been calculated. Results of the last soil survey have been presented as sketch map of actual distribution of the bottom sediments of different types.

Results of the study of dissolved protein-like substances in surface water bodies of various types (lakes, rivers, and reservoirs) are generalized in the paper. It has been shown that in surface waters of Ukraine the concentration of the dissolved organic substances of this group varies from 0.03 to 1.41 mg/L. Their contribution to the total content of carbon of dissolved organic matter (Corg) accounts for 0.3−7.8% (on the average not more than 2.6% Corg). The content of protein-like substances in the water depends on the trophic state of a water body, and also on the intensity of development of hydrobionts. The minimal concentrations of protein-like substances are registered in wintertime, whereas their maximal concentrations − in spring and summer. The protein-like substances observed in surface waters are characterized by a wide range of their molecular mass − from < 1.0 to > 70.0 kDa. The compounds with the molecular mass of < 1.0 kDa prevail among different fractions. In the total balance of dissolved protein-like substances, the maximal total content of the fractions of protein-like compounds with the molecular mass of ≤ 5.0 kD attains 45−72%. Data on the average mass molecular mass (Mw) of protein compounds and possible reasons of its variability are also given in the paper.
