The new occurrence of the bryozoan Zoobotryon verticillatum Della Chiaje, 1822 is herein recorded in multiple places throughout Azores archipelago. Where introduced, this species has caused important ecological and economical damage and therefore is regarded as invasive. In the Azores, no detrimental effects have yet been noted. The species is so far restricted to marinas (Horta, Faial Island; Vila Franca do Campo, São Miguel Island) and a natural coastal pool located near a secondary harbour (Lajes do Pico, Pico Island). A total of 29 colonies were counted during a specific survey conducted in August 2008 in the marina of Horta. The distribution of the species throughout the eastern and central island groups denotes a wide dispersion area and offers control or eradication measures a low probability of success together with the lack of harbour management practices that could effectively prevent the arrival, settlement and dispersal of non-native species transported by human-assisted means.
苔藓虫类的旋鳃苔藓虫(Zoobotryon verticillatum Della Chiaje,1822年)在亚速尔群岛多地的新出现情况在此记录。在其被引入的地方,该物种已造成了重大的生态和经济损害,因此被视为入侵物种。在亚速尔群岛,尚未观察到有害影响。到目前为止,该物种仅限于码头(法亚尔岛奥尔塔;圣米格尔岛坎普城维拉弗兰卡)以及一个位于二级港口附近的天然沿海池塘(皮库岛拉热什)。在2008年8月于奥尔塔码头进行的确切调查中,共统计到29个群体。该物种在东部和中部岛屿群的分布表明其扩散区域广泛,同时由于缺乏能够有效防止通过人为辅助手段运输的非本地物种的抵达、定居和扩散的港口管理措施,使得控制或根除措施成功的可能性很低。
