Abstract
A total of 236 species and intraspecific taxa of Bacillariophyta diatom algae from 55 genera, including 15 new for the flora of Russia, were found during the scanning electron microscope investigation of phytoplankton in Lake Glubokoye and large tributaries (Nizhnyaya Messoyakha, Purparod, Erparod, Paravanga, Nyakhataparod) in the basin of the lower course of the Messoyakha River. The maximum species diversity was recorded in the tributaries Nizhnyaya Messoyakha (117), Nyakhataparod (109), and Lake Glubokoye (97). The following species are the most widespread in the studied waterbodies: Asterionella formosa, Aulacoseira subarctica, Navicula cryptocephala, Nitzschia gracilis, Tabellaria flocculosa.
