2010年，在法国西北部的7个码头和英格兰西南部的10个码头对固着无脊椎动物的非本土物种（NIS）进行了快速评估调查，并于2013年重复进行。记录到14个NIS，其中12个在两个海岸都看到。西英吉利海峡两岸的场地占有率不同。在布列塔尼，大多数物种在2010年和2013年都出现在大多数地点。2010年，德文郡和康沃尔的场地占用率明显较低;到2013年，与布列塔尼相比的差异已经大大缩小，主要是因为2010年不常见的物种迅速殖民了其他场地。最近又有三个NIS出现在德文郡和康沃尔郡，但还没有广泛传播。它的结论是，最近引进的污损动物研究在这里建立在法国西北部的时间比在英格兰西南部，并可能向北蔓延的通道。(C)2014爱思唯尔有限公司版权所有。
Rapid assessment surveys of non-indigenous species (NIS) of sessile invertebrates were made at seven marinas in NW France and 10 marinas in SW England in 2010, and repeated in 2013. Fourteen NIS were recorded, 12 of which were seen on both coasts. Site occupancy differed between the opposite sides of the western English Channel. In Brittany, most species occurred at most sites in both 2010 and 2013. In 2010, site occupancy in Devon & Cornwall was distinctly lower; by 2013, the difference compared to Brittany had narrowed considerably, largely because of rapid colonisation of additional sites by species that were infrequent in 2010. Three more of the recent NIS are present in Devon & Cornwall but have still not become widespread. It is concluded that the recently introduced fouling animals studied here are longer established in NW France than in SW England, and have probably spread northwards across the Channel.
