As a result of scanning electron microscopy studies of phytoplankton in waterbodies of the Nizhniyj Vyg River basin, 163 species and varieties of Bacillariophyta from 56 genera have been found, including 29 new for the flora of Karelia and 8 – for Russia. The greatest species diversity has been recorded in the Vygozersk Reservoir and Matkozhnensk reach. The most widespread species in the waterbodies under study are Asterionella formosa, Aulacoseira ambigua, A. tenella, Discostella stelligera, Fragilaria crotonensis, Handmania comta, Tabellaria flocculosa.

Keywords: waterbodies, Karelia, phytoplankton, Bacillariophyta, flora, scanning electron microscopy studies
