摘要
2002年6月30日和7月1日在厦门海域2个采样点取样,对厦门东西海域自由生活海洋线虫的群落结构进行了初步比较研究。结果显示:2个站位共鉴定自由生活海洋线虫53种,西海域37种,东海域31种,其中优势种是茅咽线虫Dorylaimopsis variabilis.、萨巴线虫Sabaticria sp.、霍帕线虫Hoppcria sp.、海洋拟齿线虫Parodontophora marina和星火线虫Marylymnia sp.;对海洋线虫群落结构和生物多样性指数的比较表明,2个站位的群落多样性指数和优势种基本一致,但优势种的优势度有一定差异。西海域站位出现的种类多,但种类分布不均匀;东海域出现的种类少,但种类分布较均匀。非选择性沉积食性者(即1B型)和底上硅藻食性者(即2A型)是该海域两个站位的优势摄食类群。从优势种和摄食类群方面来看,厦门海域与台湾海峡南部、黄河口站位海洋线虫群落有一定的相似性。
Free-living marine menatodes were sampled on 30 June and 1 July 2002, at two stations in western and eastern sea area of Xiamen island. The result showed, there were 53 putative species at all, 37 for western sea area and 31 for eastern sea ares. The dominant species were Dorylaimopsis variabilis,Sabaticria sp. , Hoppcria sp. , Parodontophora marina and Marylymnia sp. respectively. The nematode community structure and diversity indices were similar at two stations, but the abundance of dominant species varied. Non-selected deposit feeder （1B type） and epigrowth feeders （2A Type） were dominant feeding group in Xiamen coastal waters. The dominant species and feeding type of free-living marine nematode community in Xiamen coastal waters are similar to that in Southern Taiwan Strait and Huanghe River Estuary.
