“…The ecological state of water bodies is assessed in terms of indicator organisms, or by comparing the structure of their communities in the sections differing in the degree of contamination. It is thought that investigations including both these approaches are most reliable (Oksiyuk and Davydov, 2013).…”

The objective of the present work was to study the structure of epiphyton in water bodies significantly differing in the degree of their contamination. In the studied water bodies, the concentration of ammonia () accounted for 0.04-74.00 mg/L; nitrite (), 0.002-1.750 mg/L; nitrate (), 0.13-58.00 mg/L; inorganic compounds of phosphorus (Pinorg), 0.041-0.272 mg/L; chloride (Cl-), 34.5-560.5 mg/L; whereas the content of organic matter (DO) was 18.0-81.0 mg O/L. The numbers of algae were determined by a direct count. Biomass was calculated by the count cell volume method. The Generic Diatom Index, the Pantle-Buck saprobic index, and the Shannon index of species diversity were used to analyze algal community structure. This study found that epiphyton responded to heavy pollution with changes in its species richness, taxonomic structure, species composition, quantitative indices, numbers and biomass structure, dominant complex, and ecological spectrum.

The structure of the communities of epiphyton algae was studied in the water bodies of the «Oleksandriya» State Dendrological Park (the town of Bila Tserkva, Ukraine). It has been found that the ponds located in the Western ravine were characterized by an essentially higher level of complex anthropogenic contamination (by inorganic compounds of nitrogen and phosphorus, chloride, sulfate, and organic substances) compared to the water bodies of the Middle and Eastern ravines. Respectively, the types of the communities of epiphyton algae (syntaxa) distinguished in the water bodies differing in the level of contamination also differed in the composition, number, and ecological characteristics of diagnostic taxa, in the species richness of epiphyton algae on the whole, in the average number of species in individual communities, in their taxonomic structure, in the quantitative indices of algae development, and in the complex of dominant species. It has been found that the communities of epiphyton algae registered in the ponds of the Western ravine belong to the association Gomphonemo parvuli-Nitzschietum paleae, whereas the communities of epiphyton occurring in the Middle and Eastern ravines - to the association Cocconeo placentulae-Naviculetum tripunctatae. The obtained data on the communities of epiphyton algae can be used for synbioindication of the state of water bodies differing in the level of contamination in performing ecological monitoring.
