fish fauna
Water quality formation in the thickets of higher aquatic plants was investigated in the river and lake ecosystems differing in the intensity of anthropic load. Trophic, saprobiological, and ecological assessment of water quality was carried out in the sections of water bodies with moderate and significant contamination. The species of higher aquatic plants and fishes adapted to the above mentioned conditions were identified.

ecological factors
Results of the study of the composition of epiphyton algae communities occurring on higher aquatic plants in the river section of the Kanev Reservoir are given in the paper. The following main structural and functional indices of epiphyton algae communities were investigated: species number, their numbers and biomass, the composition of the leading complexes, relationship between epiphyton and allochthonous algae, and the main ecological and taxonomic groups. The influence of higher aquatic plants and hydrological conditions, in particular of water dynamics, on these indices was investigated.

Paper deals with results of studies of the plankton diatoms of the Danube region of the north-west part of the Black Sea in 2005 and 2007. Species diversity of Centrophyceae has been studied. Systematic position of some centric diatoms was specified taking into account actual taxonomy. 36 species (40 intraspecific taxa) of Centrophyceae of 11 genera were identified, among them 24 new for the considered region and 7 - new for the flora of Ukraine (Actinocyclus normanii, Cyclotella ambigua, C. baltica, C. affinis, Cyclotella sp., Thalassiosira gessneri, Thalassiosira sp.). Domination of the small-sized diatoms of the genera Skeletonema and Thalassiosira was revealed.

Paper deals with results of studies (2004-2006) of the natural viral community of the oligotrophic Lake Baikal. Peculiarities of morphology and dimensional structure of 2000 free viral particles have been revealed. It was found that most part of phages (76%) belong to the order Caudovirales (tailed phages). High structural diversity of the phages of the families Siphoviridae and Myoviridae was noted, mainly in fine details of the tail section structure.
Peculiarities of the Interaction between Algae under Conditions of Different Illumination

algae
illumination
allelopathic interaction
Not only growth processes of algae, but also the intensity and pattern of their interaction, change under conditions of different illumination. The most distinct and stable unfavorable allelopathic effect was registered in the mixed culture consisting of two algae species at the intensity of illumination of 5 kLx (within the studied range from 0.5 to 25 kLx). The increase or decrease in the intensity of illumination was accompanied by the increase or decrease in the intensity of the unfavorable allelopathic effect.

Peculiarities of the influence of the manganese ions (II) in concentrations close to those in the natural water bodies on photosynthesis and respiration of the submerged higher aquatic plants Najas guadelupensis L., Ceratophyllum demersum L. and filamentous green algae Oedogonium cardiacum (Hass.) Wittr., Cladophora glomerata (L.) Kütz have been studied. It was found that impact of 5−20 μ;g/dm3 Mn2+ during 24 hours caused intensification of photosynthesis and respiration of the studied macrophytes. In the two-week experiments it was found that respiratory metabolism in N. guadelupensis and C. demersum was depressed at the lower concentration (50 μ;g/dm3 Mn2+), than in Cl. glomerata (100−200 μ;g/dm3 Mn2+); any toxic effect of 5−200 μ;g/dm3 Mn2+ for the respiratory metabolism in Oe. cardiacum was found. Accumulation of the manganese ions by macrophytes has been studied. By ability to accumulate this metal they may be arranged in a sequence: Cl. glomerata > Oe. cardiacum > N. guadelupensis > C. demersum. It is recommended to use Oe. cardiacum and Cl. glomerata as biomonitors of the water pollution by the manganese ions.
