Diversity and Peculiarities of the Formation of Stomatocysts of the Chrysophyceae in the Waterbody in the South of Western Siberia
According to the data of scanning electron microscopy, in the plankton of the shallow-water eutrophic waterbody of the Ptichiya Gavan natural park (Omsk), located in the South of Western Siberia, 105 morphotypes of stomatocysts of the Chrysophyceae were identified and combined into 20 groups. The variety of morphotypes significantly outweigh the abundance of species of the Chrysophyceae (24 species) in this waterbody. The highest variety of morphotypes (64) is characteristic of ornamented stomatocysts. The maximum abundance of stomatocysts is observed in autumn, the minimum – in winter. Unornamented stomatocysts with the spherical form without a collar predominate. The obtained data can be used to create paleolimnological reconstructions.
