Abstract

This study presents the data on the first record of Sinanodonta woodiana and S. lauta in artificially heated site of Reftinsky reservoir by warm water discharge of the Reftinsky thermal power plant (Sverdlovsk Region, the Reft River, Ob-Irtysh River Basin). This find is the northernmost habitat of these mussels of all known. The population of this species shares the invasive haplotypes: E3 ( S. woodiana ) and C3 ( S. lauta ). The population of the mussels includes individuals of various size and different age groups, and this fact could be an indirect evidence of successful naturalization of the species. The group of older specimens (over 10 years old) is more numerous in the population of S. woodiana (56%). The group of specimens of middle age (3-6 years) is more numerous in the population of S. lauta, their share is 48%. Specimens of Sinanodonta younger than 1-year-old (shell length less than 25 mm) are absent, and specimens of 2-3 years old are not numerous. Based on molecular data and archival records on fishery use, we assume that the invasion of S. woodiana and S. lauta in the Reftinsky reservoir is associated with introduction of food fish delivered from the Volga fish-farms at the end of the 20th - the beginning of the 21st century.

在中乌拉尔富廷斯基水库首次发现两种亚洲池塘贻贝(sinanodonta)

本文介绍了在雷夫廷斯基热电厂(斯维尔德洛夫斯克地区，雷夫特河，鄂-额尔齐斯河流域)人工加热的雷夫廷斯基水库遗址上首次记录的Sinanodonta woodiana和s.l auta的资料。这是已知的这些贻贝最北端的栖息地。该物种的种群具有入侵单倍型:E3 (S. woodiana)和C3 (S. lauta)。贻贝的种群包括各种大小和不同年龄组的个体，这一事实可能是该物种成功归化的间接证据。年龄较大的标本(10岁以上)在木蕨种群中数量较多(56%)。中年(3 ~ 6岁)的标本群数量较多，占种群总数的48%。小于1年(壳长小于25毫米)的Sinanodonta标本缺失，2-3年的标本数量不多。基于分子数据和渔业利用的档案记录，我们认为S. woodiana和S. lauta在Reftinsky水库的入侵与20世纪末至21世纪初伏尔加河养鱼场引入的食用鱼有关。

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..
