摘要

研究了南贝加尔湖盆地西岸沿岸0 ~ 20 m的摇尾虫群落的空间分布。区系由10个群落16种幼虫组成。研究发现,该群落物种多样性较差;香农指数在0.7到2.1比特之间变化。它们的分布受水-岩动力条件、海底沉积物类型和大型植物发育的影响。在贝雷佐维角附近的非圆形岩屑相上,摇尾蛾幼虫的最大生物量高峰出现在春季。

The spatial distribution of chironomid communities in the littoral zone (0-20 m) of the western coast of the southern Baikal basin is investigated. The fauna is composed of 16 species and forms of chironomid larvae, comprising 10 communities. It has been found that the communities are characterized by rather poor species diversity; Shannon’s index varies from 0.7 to 2.1 bit. Their distribution is affected by hydro-lithodynamic conditions, type of bottom sediments and macrophyte development. The peak of maximal biomass of chironomid larvae on the facies of non-rounded rock debris near Berezovy Cape is recorded in spring.
