Abstract

Compared to the data collected in 2016, pronounced changes in the malacofauna inhabiting the Shershnevskoye Reservoir (city of Chelyabinsk) were discovered in August 2022 at inshore sampling stations near the dam. Mollusks of the family Sphaeriidae have disappeared from the community of bivalves. The species Dreissena polymorpha (Pallas, 1771) of the family Dreissenidae predominated the malacofauna in 2022. Analysis of the size and age structure of the D. polymorpha population showed that the maximum age of mollusks was 5 years. The collected data indicate that D. polymorpha has successfully invaded the Shershnevskoye Reservoir in the period since 2016 and naturalized there.

Dreissena polymorpha（Pallas，1771 年）入侵谢尔什涅夫斯科耶水库（车里雅宾斯克市）

摘要与 2016 年收集的数据相比，2022 年 8 月在大坝附近的近岸采样站发现，居住在谢尔盖耶夫斯科耶水库（车里雅宾斯克市）的孔雀鱼群发生了明显变化。双壳贝类群落中已经消失了 Sphaeriidae 科的软体动物。在 2022 年的双壳类群中，蝶形花科的 Dreissena polymorpha（Pallas，1771 年）物种占多数。对 D. polymorpha 种群大小和年龄结构的分析表明，软体动物的最大年龄为 5 岁。收集到的数据表明，自 2016 年以来，D. polymorpha 已成功入侵谢尔什涅夫斯科耶水库，并在那里归化。

期刊介绍： Russian Journal of Biological Invasions publishes original scientific papers dealing with biological invasions of alien species in both terrestrial and aquatic ecosystems and covers the following subjects:description of invasion process (theory, modeling, results of observations and experiments): invasion corridors, invasion vectors, invader species adaptations, vulnerability of aboriginal ecosystems;monitoring of invasion process (reports about findings of organisms out of the limits of natural range, propagule pressure assessment, settling dynamics, rates of naturalization);invasion risk assessment; genetic, evolutional, and ecological consequences of biological invasions of alien species; methods, means of hoarding, processing and presentation of applied research data (new developments, modeling, research results, databases) with factual and geoinformation system applications;use of the results of biological invasion research (methods and new basic results) under the study of marine, fresh-water and terrestrial species, populations, communities and ecosystems; control, rational use and eradication of the harmful alien species..
