The study of attached algal communities (phytoperiphyton), including the analysis of their floristic composition and spatial distribution, was carried out in River Teno and its tributaries. Altogether 215 taxa of algae were identified from 49 locations. In the streams investigated, attached algal communities characteristic of oligotrophic waters developed. Diatoms – mainly typical attached forms Tabellaria flocculosa, Synedra ulna, Achnanthes minutissima, Eunotia pectinalis, Cymbella affinis, were most frequent and abundant. Biomass, ranging from 0.4 to 1180 mg m², was the highest when filamentous green algae Zygnema, Bulbochaete and Oedogonium dominated. The river channel morphometry, riparian canopy density, depth, flow rate, substratum particle-size composition determined the spatial dynamics of periphyton in the watercourses.
