摘要

摘要全球航运促进了污染生物进入新的地理区域。近几十年来,海上运输的增加带来了前所未有的发展,海洋沿海水域已成为全球入侵最严重的栖息地之一。腹水是最成功的入侵者之一。尽管冰岛在地理和海洋上与世隔绝,但它并没有被排除在接受区域之外。Ascidians已经成功地在冰岛建立了稳定的种群,这些种群正在西南地区缓慢扩张。在这里,我们报道了在冰岛水域首次记录到的粗糙腹水杆菌,以及七种非本土腹水杆菌在冰岛西南部港口的传播。我们将它们的相对丰度与2018年的调查进行了比较。这些海鞘的大部分不仅存在于温带大西洋,也存在于西北太平洋和温带澳大拉西亚,这表明海鞘动物群的全球同质化正在人为化的沿海地区出现。气候变化导致的海面温度上升可能会继续支持这种情况的发展,导致生物多样性丧失,这可能会危及生物资源,并产生严重的经济影响。

Recent spread of non-indigenous ascidians (Chordata: Tunicata) in Icelandic harbours
ABSTRACT Global shipping facilitates the introduction of fouling organisms to new geographic areas. The increase in maritime transport in recent decades has led to unprecedented development, where marine coastal waters have become one of the most invaded habitats around the globe. Among the most successful invaders are ascidians. Despite the geographic and oceanographic isolation of Iceland, it is far from being excluded as a recipient region. Ascidians have successfully been able to establish stable populations in Iceland that are slowly expanding around the SW region. Here we report the first record of Ascidiella scabra in Icelandic waters, and the spread of seven non-indigenous ascidians across the S-SW Icelandic harbours. We compare their relative abundances to our survey from 2018. The bulk of these ascidians is not only present in the temperate Atlantic Ocean, but also in the Northwest Pacific and temperate Australasia, revealing that global homogenization of the ascidiofauna is emerging in anthropized coastal areas. The rising of sea surface temperature, driven by climate change, is likely to continue to support the development of this scenario leading to biodiversity loss, which could endanger living resources with severe economic impacts.

期刊介绍: Marine Biology Research (MBRJ) provides a worldwide forum for key information, ideas and discussion on all areas of marine biology and biological oceanography. Founded in 2005 as a merger of two Scandinavian journals, Sarsia and Ophelia, MBRJ is based today at the Institute of Marine Research, Bergen, Norway. The Journal’s scope encompasses basic and applied research from all oceans and marine habitats and on all marine organisms, the main criterium for acceptance being quality.
