Colonization dynamics of protozoan communities were investigated at a depth of 1 m in the coastal waters of the Yellow Sea, northern China from May to June 2019, using modified glass slide (mGS) and modified polyurethane foam unit (mPFU) systems. The colonization process and growth curves of protozoa were well fitted to the MacArthur-Wilson and logistic models in both systems, respectively. However, they showed significant differences in both colonization dynamics and biodiversity/functional parameters between the mGS and mPFU systems. The H' (species diversity), the G (colonization rate), and A (maximum abundance) were higher, while the value of T (the time for reaching 90% equilibrium species number) was lower in the mGS system than those in the mPFU system. Multivariate analyses demonstrated that protozoa showed different models of colonization dynamics in both systems. The results suggest that the mGS system might be more effective than the mPFU system in marine bioassessment surveys.
2019 年 5 月至 6 月，在中国黄海近岸海域 1 米深处，采用改良玻璃载片（mGS）和改良聚氨酯泡沫块（mPFU）系统，研究了原生动物群落的定殖动态。在这两种系统中，原生动物的定殖过程和生长曲线均分别很好地符合麦克阿瑟-威尔逊和逻辑斯蒂模型。然而，它们在定殖动态和生物多样性/功能参数方面均表现出显著差异。mGS 系统的 H'（物种多样性）、G（定殖率）和 A（最大丰度）较高，而 T（达到 90%平衡物种数所需的时间）值则低于 mPFU 系统。多元分析表明，原生动物在这两种系统中表现出不同的定殖动态模型。研究结果表明，mGS 系统在海洋生物评估调查中可能比 mPFU 系统更有效。
