Diversity of Stomatocysts of Golden Algae (Chrysophyceae) from the Plankton of Reservoirs of the Mountain Forest Zone of South Urals

According to the data of scanning electron microscopy, in the plankton of the reservoirs, lakes, rivers of the mountain-forest zone of Southern Urals, 33 morphotypes of stomatocysts of Chrysophyceae, 8 of which were found for the first time in Russia, one morphotype was described as new to science. The description of each morphotype is accompanied by a SEM micrography, geographical location, and environmental characteristics. Unornamented stomatocysts with a spherical form are predominant in abundance in plankton. Ornamented stomatocysts with a spherical form are predominant in diversity in plankton. The maximum diversity of stomatocysts is observed in spring and in autumn. The revealed high diversity of stomatocysts indicates a significant diversity of golden algae in the South Ural region.
