Abstract

Mollusks from the Viviparidae family are one of the invertebrates that actively settle outside their natural habitats. Alien representatives of this family dwell in the waters of North and South America, Europe, and Asia. This paper presents the results of long-term studies of Viviparus viviparus L. unintentionally introduced into the Novosibirsk Reservoir. The effect of types and concentrations of organic substances on the spatial distribution of V. viviparus in the reservoir has been studied. It is found that the formation of denser mollusks settlements (when compared to the natural areal) occurred in the Novosibirsk Reservoir due to its favorable environmental conditions. The Harmonia+ Protocol was used to assess the risk of V. viviparus invasion into water bodies of the Ob River basin, as well as the invasion consequences for its aquatic ecosystems. It is shown that water bodies of the Middle Ob basin are suitable for V. viviparus; the risk of further mollusk spread is estimated as high.

Viviparus viviparus L.空间分布的因素及风险评估。鄂毕河流域水生生态系统的入侵

摘要

Viviparidae家族的软体动物是活跃在其自然栖息地外部的无脊椎动物之一。这个家庭的外星人代表居住在北美和南美，欧洲和亚洲的水域。本文介绍了无意引入新西伯利亚水库的Viviparus viviparus L.的长期研究结果。研究了有机物的种类和浓度对水库中Viviparus空间分布的影响。发现新西伯利亚水库由于环境条件优越，形成了较稠密的软体动物定居点（与自然区域相比）。使用Harmonia +方案评估Viviparus的风险入侵鄂毕河盆地的水体，以及对其水生生态系统的入侵后果。结果表明，Ob盆地中部的水体适合于V. viviparus ; 软体动物进一步传播的风险估计很高。
