Spatial patterns of planktonic ciliate communities for assessment of marine environmental status were studied from June 2007 to May 2008 in Jiaozhou Bay, Qingdao, northern China. Ciliate communities were sampled biweekly at five sampling sites with a spatial gradient of environmental stress. Multivariate/univariate analyses demonstrated that: (1) the planktonic ciliate community structures represented significant differences among the five sites; (2) spatial patterns of the ciliate communities were significantly correlated with environmental variables, especially the nutrients nitrate nitrogen (NO₃-N) and soluble reactive phosphates (SRP); (3) five dominant species (e.g., Rimostrombidium veniliae, Strombidium capitatum, Mesodinium pupula and Strombidinopsis acutum) were significantly correlated with nitrogen and/or SRP; and (4) both species richness and species diversity indices were correlated with NO₃-N and salinity. These results suggest that planktonic ciliated protozoa might be used as a robust bioindicator of marine water quality.
本研究于 2007 年 6 月至 2008 年 5 月期间在胶州湾（中国青岛）采集了浮游纤毛虫样本，以评估海洋环境状况。纤毛虫群落采用空间梯度法在五个采样点进行了双周采样。多变量/单变量分析表明：（1）五个采样点的浮游纤毛虫群落结构存在显著差异；（2）纤毛虫群落的空间格局与环境变量显著相关，尤其是硝酸盐氮（NO₃-N）和可溶性活性磷酸盐（SRP）；（3）五种主要物种（如 R. veniliae、Strombidium capitatum、M. pupula 和 S. acutum）与氮和/或 SRP 显著相关；（4）物种丰富度和多样性指数均与 NO₃-N 和盐度相关。这些结果表明，浮游纤毛虫可能被用作海洋水质的可靠生物指标。
