Abstract

The presence of the invasive amphipod Gmelinoides fasciatus (Stebbing, 1899) has been established for the first time in the watercourse of the basin of Lake Vodlozero (Novguda River, a tributary of the Ileksa River), which is located on the territory of the Vodlozersky National Park (northwestern Russia). The new habitat is at a considerable distance from the previously known ones. The shortest route through water bodies (Ileksa River–Vodlozero Lake–Sukhaya Vodla River–Vodla River–Onega Lake) is about 180 km. This raises questions about the path and mode of spread of the invasive species. Along with migration through water bodies, it is proposed to consider the version of introduction of amphipods by tourists, in particular fishermen, with equipment or bait. A detailed survey of the littoral zone of Lake Vodlozero is recommended to determine the extent of the invasive settlement.

在沃德洛泽罗湖盆地（俄罗斯）首次发现入侵片脚类 Gmelinoides fasciatus

摘要

首次在沃德洛泽罗湖（诺夫古达河，伊莱克萨河的支流）盆地的水道中发现了入侵性片脚类 Gmelinoides fasciatus（Stebbing，1899），该湖位于沃德洛泽尔斯基地区国家公园（俄罗斯西北部）。新的栖息地与之前已知的栖息地相距相当远。通过水体（伊莱克萨河 - 沃德洛泽罗湖 - 苏哈亚沃德拉河 - 沃德拉河 - 奥涅加湖）的最短路线约为 180 公里。这引发了有关入侵物种传播路径和模式的问题。除了通过水体迁徙外，建议考虑由游客，特别是渔民使用设备或诱饵引入片脚类动物的版本。建议对沃德洛泽罗湖沿岸地区进行详细调查，以确定入侵定居点的范围。
