Diatom algae from some water bodies of northeastern West Siberia: Communication 2. Pennatophyceae

摘要

In the studied water bodies of the northeast of the Western Siberia, Bacillariophyta dominates the flora of planktonic organisms by species abundance. Among them, class Pennatophyceae is distinguished by the highest species richness. The first electron microscopic studies of pennate diatom algae allowed obtaining complete data on the species composition of Pennatophyceae at the modern level. Discovered were 213 taxa from 53 genera, including 98 new to the region, 56 new and rare to the flora of Russia, and forms identified only to the genus. The taxonomy of the genera Nitzchia, Stauroneis, Pinnularia, and Navicula s.s. is the richest.
