Abstract

Clams of the genus Corbicula were discovered for the first time in the downstream of the Don River in the area of the warm channel of the Novocherkassk State District Power Plant in 2017. They were identified as Corbicula fluminea according to conchiological features. The objective of this study is to confirm the species identification using the molecular genetic methods and determine the morphotype by shell morphometric indices: frontal (D/L) and sagittal (H/L) curvature (=Index of Roundness) and convexity ((H + D)/L). According to the results obtained, the Asian clam was assigned to the European invasive lineage of the FW5 haplotype, taxonomically assigned to C. fluminea and morphologically to the R morphotype.

关于顿河下游亚洲蛤蜊 Corbicula fluminea (O.F. Müller, 1774) 的新数据

摘要 2017 年，在顿河下游新谢尔卡斯克国营地区发电厂温水道区域首次发现了蚬属。根据贝壳学特征，它们被确定为Corbicula fluminea。本研究的目的是利用分子遗传学方法确认物种鉴定，并通过贝壳形态指数确定形态类型：正面（D/L）和矢状（H/L）弯曲度（=圆度指数）和凸度（（H + D）/L）。根据所得结果，亚洲蛤蜊被归入 FW5 单倍型的欧洲入侵系，在分类学上被归入 C. fluminea，在形态学上被归入 R 形态型。

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..
