Abstract

Amphipods play the leading role among alien species in Lake Ladoga. In particular, the Baikal species Micruropus possolskii Sowinsky, 1915 is becoming increasingly important here. The purpose of this paper is to present updated data on the appearance of M. possolskii in Lake Ladoga and on the temporal and spatial dynamics of its development and expansion in this water body. The species was initially recorded in the Shchuchiy Bay of Lake Ladoga in 2003. Its spread to the south to the Petrokrepost Bay (where it was recorded in 2017) is shown. The further expansion of the species in Lake Ladoga and its significant quantitative development in the colonized biotopes and possible expansion to Lake Onega and the Neva Bay of the Gulf of Finland are expected.

拉多加湖（Micruropus possolskii Sowinsky，1915）（两栖动物，甲壳纲）在拉多加湖的扩张动力学

摘要

两栖动物在拉多加湖的外来物种中起着主导作用。特别是1915年的贝加尔湖物种Micruropus possolskii Sowinsky在这里变得越来越重要。本文的目的是提供有关拉多加湖中波梭菌的外观及其在该水体中发育和扩张的时空动态的最新数据。该物种最初于2003年记录在拉多加湖的Shchuchiy湾中。该物种向南传播到Petrokrepost湾（2017年在此记录）。预计拉多加湖物种的进一步扩展及其在定殖生物群落中的显着定量发展，并有望扩展到奥涅加湖和芬兰湾的涅瓦湾。
