Abstract

Using scanning electron microscopy, 33 morphotypes of stomatocysts of Chrysophyceae are found in the plankton of the reservoirs, lakes, and rivers of the mountain–forest zone of the Southern Urals; 8 of them are noted in Russia for the first time, and 1 is 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 high diversity of stomatocysts indicates a significant diversity of golden algae in the Southern Ural region.

乌拉尔南部山地森林区水库浮游生物中金色藻类(菊形目)口囊的多样性
摘要 利用扫描电子显微镜,在南乌拉尔山林区的水库、湖泊和河流的浮游生物中发现了 33 种菊石目动物的气孔囊形态;其中 8 种是首次在俄罗斯发现,1 种是科学界的新发现。每种形态的描述都附有扫描电镜显微照片、地理位置和环境特征。无装饰的气孔囊呈球形,在浮游生物中数量最多。在浮游生物中,具有球形形态的装饰性气孔囊的多样性占主导地位。春季和秋季口囊的多样性最高。气孔囊的高度多样性表明南乌拉尔地区的金藻具有显著的多样性。
