在东北部西西伯利亚水体的浮游植物中，硅藻门是7个最丰富的藻类部门的优势群体，Centrophyceae类成员的出现率从27%到100%不等。扫描电子显微镜显示了占德令哈湖、德令哈河和Bol'shaya Kheta河浮游植物主导地位的Centrophyceae类的完整物种组成（Aulacoseira，3种; Cyclostephanos，1种; Cyclotella，5种; Discostella，1种; Melosira，1种; Pliocaenicus，1种; Puncticulata，1种; Stephanodiscus，6种）。在塔兹河的浮游植物纲Centrophyceae现在有一个新的成员，Punciculata radiosa。本文报道了西西伯利亚藻类植物群小环藻属的新种：小环藻C. arctica、北极角蝉C. comensis和C.涡状。这些发现有助于更精确地确定稀有类群的范围，并为C. comensis和Stephanodiscus invisitatus。
In the phytoplankton of northeastern West Siberian water bodies, Bacillariophyta were a dominant group of the 7 most abundant algal divisions, with the occurrence of the members of the class Centrophyceae varying from 27 to 100%. Scanning electron microscopy revealed complete species composition of the class Centrophyceae that dominates the phytoplankton of Lake Delingde, the Delingde and Bol’shaya Kheta rivers (Aulacoseira, 3 species; Cyclostephanos, 1; Cyclotella, 5; Discostella, 1; Melosira, 1; Pliocaenicus, 1; Puncticulata, 1; Stephanodiscus, 6). The phytoplankton of the class Centrophyceae in the Taz River now has a new member, Puncticulata radiosa. New species of the genus Cyclotella in West Siberian algal flora were revealed: C. arctica, C. comensis, and C. vorticosa. The findings helped more precisely define the ranges of the rare taxa and add new diagnostic features to the diagnoses of C. comensis and Stephanodiscus invisitatus.
