Abstract

Abstract For the bioassessment of tropical marine ecosystem, a survey of protozoa colonizing artificial substrate was conducted in the coastal waters of northern Bay of Bengal, Bangladesh. Protozoan samples were collected using glass slides from 1 and 2 m water depths at time intervals of 3, 7, 10, 14, 21, and 28 days during winter and monsoon seasons. Thus, the colonization processes of protozoa were assigned into three stages namely the initial (3 days), transitional (7 days), and equilibrium stages (10–28 days) at two depths in two seasons. Regression analyses demonstrated that the colonization dynamics of protozoa were well fitted to the MacArthur-Wilson model and logistic equation. Species richness reached equilibrium after 10–14 days and species abundance was maximum at a depth of 1 m. These results suggest that samples of protozoa can be collected at 1 m depth in winter season for monitoring the ecological health of tropical marine ecosystems.

热带海洋生态系统中周边原生动物的定植动态
摘要为了对热带海洋生态系统进行生物评价,在孟加拉国孟加拉湾北部沿海水域进行了原生动物定殖人工基质的调查。在冬季和季风季节,以3、7、10、14、21和28天的时间间隔,使用玻璃载玻片从1米和2米水深采集原生动物样本。因此,原生动物的定殖过程分为三个阶段,即两个季节中两个深度的初始阶段(3天)、过渡阶段(7天)和平衡阶段(10-28天)。回归分析表明,原生动物的定殖动力学符合MacArthur-Wilson模型和logistic方程。物种丰富度在10-14天后达到平衡,物种丰富度在1米深处达到最大。这些结果表明,在冬季可以在1米深度采集原生动物样本,用于监测热带海洋生态系统的生态健康。
