1976年和1977年，研究人员对加利福尼亚蒙特利湾浅水站收集的网状浮游生物进行了研究。主要浮游植物类型为浅海硅藻。利用Fager’s重组分析，确定了重复出现的物种群及其与水文季节相关的分布。在戴维森海流和上涌期，浅海组相对丰富；然而，许多物种在一年中的大部分时间都存在。海洋种群和物种的出现是季节性的，与平流事件有关。一个浅海物种组在数量上具有压倒性的重要性，但在该组内，浮游植物种群的相对丰度在该组的物种之间发生了显著的季节性变化。这一组似乎由常驻物种组成，并可能在当地作为营养细胞或底栖动物休息阶段保留下来。蒙特雷湾的物种循环在很大程度上被认为是本地物种演替或循环的结果，而由形容词过程引入的物种似乎不太重要。该研究表明，在“种子种群”中存在的物种，无论是作为营养细胞还是作为底栖动物的休息阶段，可能对物种的生长速度在理解和预测沿海浮游植物组合的组成和相对丰度方面很重要。
Netplankton collections from shallow-water stations in Monterey Bay, California were examined for 1976 and 1977. The predominating phytoplankton forms were neritic diatom species. Recurrent species groups were identified using Fager's regroup analysis and their distributions related to hydrographic seasons. Neritic groups were relatively more abundant during the Davidson Current and upweiling periods; however, many of the species were present throughout much of the year. The appearance of oceanic groups and species was seasonal and associated with advective events.One neritic species group was of overwhelming numerical importance but within the group conspicuous changes in relative abundance of phytoplankton populations occurred seasonally among species from this group. This group appears to be composed of resident species and may be locally retained as vegetative cells or benthic resting stages. Species cycles in Monterey Bay may be regarded as largely the result of suc-cessional changes or cycles of autochthonous species, while species introduced by adjective processes appear to be of minor importance.The study has suggested that the presence of species in a ‘seed population’, either as vegetative cells or benthic resting stages, may be important as the growth rate of the species in understanding and predicting composition and relative abundance in coastal phytoplankton assemblages.
