研究了北太平洋中央环流贫营养沃茨中甲藻属角藻（Ceratium）的种类组成和分裂速率。尽管营养水平较低，但角藻的分裂率相对较高。根据计算，沙鼠的倍增时间为5.2-7.5天，在10个最丰富的物种中，倍增时间为4.0 - 9.2天。51种角藻进行了鉴定，其丰富的等级顺序是显着恒定的最大的时间和空间尺度的检查（9个月和755公里）。铈相对较高的分裂率加上其一贯的低丰度支持从其他数据得出的结论，即在这种环境中近似稳态条件。
Species composition and division rates were examined for a ylopulation of the dinoflagellate genus Ceratium from oligotrophic waters of the North Pacific central gyre. Division rates of Ceratium were high relative to those in other oceanic regions despite the low nutrient levels. Doubling times were calculated to be 5.2-7.5 days for the gerlus and ranged from 4.0 to 9.2 days among the 10 most abundant species. Fifty-one species of Ceratium were identified, and their rank order of abundance was remarkably constant over the largest temporal and spatial scales examined (9 months and 755 km). Ceratium’c relatively high division rate coupled with its consistently low abundance supports the conclusion from other data that steady state conditions are approximated in this environment.
