| 摘要: |
| 为了解渤海湾砂壳纤毛虫丰度、生物量及种类组成, 于2011年春季和夏季在渤海湾天津近岸海域进行砂壳纤毛虫群落的采样调查。两个季节砂壳纤毛虫丰度、生物量、优势种及群落结构均有显著的不同。春季砂壳纤毛虫丰度的范围为0～1608个/L, 生物量为0.00～20.03 μg /L; 夏季砂壳纤毛虫丰度的范围为2～313个/L, 生物量为0.03～4.04 μg /L。共鉴定出砂壳纤毛虫5属15种, 其中拟铃虫属(Tintinnopsis)种类最多。春季的主要优势种为运动类铃虫 (Codonellopsis mobilis, 优势度为0.79), 夏季的主要优势种为斯氏拟铃虫 (Tintinnopsis schotti, 优势度为0.28)和诺氏薄铃虫 (Leprotintinnus nordqvisti, 优势度为0.28)。春季砂壳纤毛虫群落的物种丰富度、Shannon指数和Pielou指数均明显低于夏季。 |

| Abstract: |
| The community structure and seasonal dynamics of tintinnids in Bohai Bay were investigated during spring and summer, 2011. Tintinnid abundance, biomass, and community structure were different in spring and summer. In spring, tintinnid abundance ranged from 0 to 1608 ind./L, and the biomass was in the range of 0.00–20.03 μg/L; in summer, tintinnid abundance ranged from 2 to 313 ind./L, and the biomass was in the range of 0.03–4.04 μg/L. Tintinnid abundance and biomass were mainly concentrated in the coastal areas during spring and summer. Fifteen tintinnid species were identified, nine of which were in the genus Tintinnopsis. The most dominant species were Codonellopsis mobilis in spring and Tintinnopsis schotti and Leprotintinnus nordqvisti in summer. Species richness, the Shannon index, and the Pielou index were all higher in summer than in spring. |
