Abstract

In lakes of the Upper Volga (Yaroslavl district) and in the lower course of the Sura River (Middle Volga), closely related rotifers - common for both studied regions native K. longispina and alien K. bostoniensis - were found. Both species occur all year round and more frequently in spring or autumn, when they are the most abundant. Alien rotifer K. bostoniensis occurred not only simultaneously with indigenous species, but also separately, in more shallow waterbodies. Alien species is more tolerate to bathymetry, basin form, transparency and the trophy state of the waterbody. This likely facilitates wider distribution of the K. bostoniensis in the Sura basin waterbodies compared to indigenous species. Alien species K. bostoniensis spread relatively quickly in the Sura basin without any harm to closely related indigenous species, to which it is not a competitor.

boston Kellicottia (rousselet, 1908)和longispina (kellicott, 1879)(轮虫目:臂尾虫科)在伏尔加河中上游湖泊的发生和传播格局

在伏尔加河上游(雅罗斯拉夫尔地区)和苏拉河下游(伏尔加河中部)的湖泊中，发现了密切相关的轮虫，这些轮虫在两个研究地区都是常见的。这两个物种全年都有，春季或秋季更为频繁，数量最多。在较浅的水体中，外来轮虫可与本土轮虫同时发生，也可单独发生。外来物种对水深、盆地形态、透明度和水体的战利品状态有较强的容忍度。与本地物种相比，这可能促进了波士顿k.s tonensis在苏拉盆地水体中更广泛的分布。外来种波士顿狐猴在苏拉盆地的传播速度相对较快，对亲缘关系较近的本土物种没有任何危害，不是本土物种的竞争对手。

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..
