Abstract

ABSTRACT In the Mediterranean Sea, the north-east Atlantic seaweed Saccorhiza polyschides (Lightfoot) Batters is uncommon. The only permanent populations are located in the Alboran Sea near the Strait of Gibraltar and the Strait of Messina (Italy). In contrast, since the early 19th century, several sightings, on ship's hulls or in harbours, reflect the dispersal of propagules which failed to establish in the Mediterranean. Here we report a new sighting of Saccorhiza polyschides, near the port of Jijel, Algeria. This first new record in the Mediterranean for more than a century indicates that the dispersal of propagules continues today. In addition, because of its spectacular size and ease of its observation, it sheds light on the expansion routes of a species at the limit of their current range area.

在阿尔及利亚(地中海)发现多足(光足)蝠(褐藻科，层桩目):对范围扩展路线的洞察

摘要:在地中海，东北大西洋海草(Saccorhiza polyschides)并不常见。唯一的常住人口位于直布罗陀海峡和墨西拿海峡附近的阿尔博兰海(意大利)。相比之下，自19世纪初以来，在船体或港口的几次目击，反映了繁殖体的扩散，这些繁殖体未能在地中海建立。在这里，我们报告一个新的Saccorhiza polyschides，在阿尔及利亚的Jijel港附近。这是地中海一个多世纪以来的第一个新记录，表明繁殖体的传播今天仍在继续。此外，由于其壮观的大小和易于观察，它揭示了一个物种在其当前活动范围范围的极限下的扩张路线。
