Abstract

In a study of the rate of production of four species of planktonic Foraminifera in the region of the California Current it was found that their life spans are of the order of 1 month. Reproduction seems to take place mainly in the upper hundred meters. Results are in contrast to previous evidence presented in favor of yearly life cycles and maturing at great depth in other species of planktonic Foraminifera.

摘要

在一项关于加利福尼亚洋流区域四种浮游有孔虫的繁殖率研究中，发现它们的寿命约为1个月。繁殖似乎主要发生在海面下一百米以内。这一结果与之前所提出的支持其他种类浮游有孔虫存在年度生命周期并在深海成熟的证据形成了对比。
