摘要丝状马尾藻（Sargassum filicinum Harvey）是亚洲东北部沃茨潮下带重要的生态工程者，它形成的海洋森林为无脊椎动物和鱼类提供了栖息地。2003年首次发现于美国加利福尼亚州的长滩港。filicinum被认为主要发生在加州海峡群岛和墨西哥恩塞纳达附近。然而，在2007年至2009年的一项调查中，我们发现S。在Natividad岛附近的filicinum，这是其在墨西哥太平洋最后记录位置以南550公里的范围的延伸。形态学和分子生物学数据支持该物种的鉴定。考虑到它从恩塞纳达到Natividad岛的传播速度（4年）比鼠尾藻（14年）快，S。filicinum可能遵循S.到达墨西哥的亚热带太平洋沿岸。虽然S. muticum已经在当地海藻植物群中得到很好的建立，S. filicinum可能会取代本地的马尾藻物种，并改变当地海洋植物区系的组成。
Abstract Sargassum filicinum Harvey is an important ecological engineer in the subtidal regions of northeastern Asian waters, as it forms marine forests that provide shelter for invertebrates and fishes. First discovered in Long Beach Harbor, CA, USA, in 2003, S. filicinum was thought to occur mainly in the California Channel Islands and near Ensenada, Mexico. However, during a survey from 2007 to 2009, we found S. filicinum off Isla Natividad, which is an extension of its range 550 km south of its last recorded location in the Mexican Pacific. Morphological and molecular data support the identification of the species. Considering its faster spread from Ensenada to Isla Natividad (4 years) than Sargassum muticum (14 years), S. filicinum may follow the path of S. muticum and arrive at the subtropical-tropical Pacific coast of Mexico. Although S. muticum has become well established within the local seaweed flora, S. filicinum may replace native Sargassum species and change the composition of local marine floras.
