摘要

摘要对中乌拉尔山脉南部湖泊的小草进行了区系调查，发现有9种属于Euastrum属，8个分类群属于Micrasterias属。其中4个分类群为乌拉尔地区新记录，分别为德国鼠鼩、阿拉木图鼠鼩、毛毛鼠鼩、马哈布氏鼠鼩，其余4个分类群为乌拉尔中部地区首次发现，分别为疣鼠鼩、美洲鼠鼩、富尔卡塔鼠鼩和长尾鼠鼩。典型对应分析表明，大多数藻类在微酸性水体中更丰富，并且主要发生在底栖生物栖息地。

Genera Euastrum and Micrasterias (Charophyta, Desmidiales) from Fens in the Southern Part of Middle Urals, Russia

Abstract The floristic survey of the desmids in lakes of the southern part of Middle Urals revealed nine species representing the genus Euastrum and eight taxa belonging to the genus Micrasterias. Among them, four taxa (Euastrum germanicum, E. verrucosum var. alatum, Micrasterias fimbriata, M. mahabuleshwarensis var. wallichii) were new records to the Ural Region, whereas the other four taxa (Euastrum verrucosum, Micrasterias americana, M. furcata and M. truncata) were found for the first time in Middle Urals. Canonical correspondence analysis, which was performed to assess habitat preferences of the studied algae, showed that most species were more abundant in slightly acidic water and occurred predominantly in benthic habitats.
