Abstract

The article analyzes the distribution of alien polychaetes in the northern part of the Black Sea using the original material collected in 1998–2019, which includes ten species from five families, and published data. The family Spionidae is represented by five species; two species belong to the family Serpulidae; and the families Pilargiidae, Scalibregmatidae, and Sabellidae are represented by one species each. The distribution of polychaetes across the biotopes of the northern part of the Black Sea is as follows: Polydora cornuta Bosc, 1802 and Streblospio gynobranchiata Rise & Levin, 1998 are widely distributed on soft bottom sediments in the shallow area of semi-enclosed bays, lagoons and ports. Similarly, Sigambra tentaculata (Treadwell, 1941) is recorded from soft substrates in shallow waters, but largely occurs at the coast that fronts on the open waters. Dipolydora quadrilobata (Jacobi, 1883) is the only representative of the deep-water area of the Black Sea. The species Marenzelleria neglecta Sikorski & Bick, 2004 and Hyboscolex cf. pacificus (Moore, 1909) are occasionally encountered on soft bottom sediments. Hydroides dianthus (Verrill, 1873) and Pseudopotamilla cf. reniformis (Bruguière, 1789) are recorded from fouling (or other styles of attachment) on hard substrates, as well as Ficopomatus enigmaticus (Fauvel, 1923), whose status of an introduced species needs clarification. Two species, Polydora websteri Hartman in Loosanoff & Engle, 1943 and H. dianthus, which settle on the shells of mollusks, while negatively affecting them, can be classified as invasive species. In the Black Sea basin, polychaetes were probably introduced at the pelagic stage with ballast waters or in fouling of ships. The species F. enigmaticus, P. cornuta, and S. tentaculata introduced to the Black Sea more than 60 years ago can be considered fully naturalized.

黑海北部生物群落中外来多毛类的分布

摘要

本文使用1998-2019年收集的原始材料（包括来自五个科的10个物种）分析了黑海北部外来多毛鱼类的分布，并发布了数据。Spionidae科有5种。有两个属于剑孢科。Pilargiidae科，Scalibregmatidae科和Sabellidae科分别由一个物种代表。黑海北部生物群落中多毛类的分布如下：Polydora cornuta Bosc，1802和Streblospio gynobranchiata Rise＆Levin，1998年广泛分布在半封闭海湾，泻湖浅层区域的软底部沉积物上。和端口。同样地，西格布拉（Sigambra tentaculata）（Treadwell，1941年）是从浅水区的软质基质中记录下来的，但主要发生在开放水域前沿的海岸上。Dipolydora quadrilobata（Jacobi，1883）是黑海深水区的唯一代表。该物种Marenzelleria neglecta西科尔斯基与比克，2004年和Hyboscolex比照 太平洋（Moore，1909）偶尔会在软底沉积物上遇到。氢化石竹（Verrill，1873）和假马铃薯（参见Pseudopotamilla cf. 在坚硬的底材以及Ficopomatus enigmaticus上的结垢（或其他类型的附着）中记录了肾形目（Bruguière，1789年）（Fauvel，1923年），其引进物种的地位需要澄清。两种物种，定居在软体动物的壳上，虽然对软体动物的壳产生负面影响，但它们定居在软体动物的壳上，同时对它们造成负面影响，这两种物种分别位于Loosanoff＆Engle的Polydora websteri Hartman，1943年和H. dianthus。在黑海盆地，可能在浮游阶段与压舱水或船舶结垢时引入了多毛et。超过60年前引入黑海的F. enigmaticu s，P。cornuta和S. tentaculata物种可以认为已完全归化。
