亚热带海湾浮游纤毛虫群落结构及其与环境的关系
Ciliate community structures in typical subtropical bays and their relationships with environment
Abstract
海洋浮游纤毛虫是海洋微型浮游生物群落的重要组成部分，也是微型生物食物网中的重要环节。纤毛虫对水环境变化十分敏感，对水质和生态系统的健康程度有着良好的指示作用。本研究分别在南海北部湾北部和福建省深沪湾进行浮游纤毛虫样品的采集，对纤毛虫群落的种类组成和时空分布进行研究，分析其群落结构特征，并且探讨了影响浮游纤毛虫群落变动的主要环境因素。主要研究结果如下： 1）春季，对北部湾北部表层海域的研究，共鉴定纤毛虫36种，隶属于3目（寡毛目Oligotrichida，刺钩目Haptorida，丁丁目Tintinnida），13属。 表层海域的浮游纤毛虫呈现斑块状分布的特点，总纤毛虫和无壳纤毛虫的密集区都... Ciliates are significant components of microplankton communities in the ocean and play a crucial role in microbial food webs. By virtue of their sensitive reaction to environmental changes, they have been considered as effective bioindicators of water quality and ecosystem. This study was carried out in the northern Beibu Gulf, South China Sea and Shenhu Bay in Fujian Province. The taxonomic compo...
