Dinoflagellate Swimming Orientation from an Ecological Perspective

p . .项目摘要：研究将研究在几种环境背景下，在diel垂直迁移过程中，不同的细胞内部特征（例如，叶绿体位置，DNA合成，脂质储存）如何与海洋鞭毛藻方向相关。对这些关系的理解将导致模型的发展，预测光合种群的生长和生存如何在空间和时间上变化。这种可变性将直接关系到一个物种在给定水团中的竞争能力，关系到水汇聚处斑块的发展，关系到水柱内致密层的形成。

P.I.. Kamykowski, Daniel Proposal #: 9503253 PROJECT ABSTRACT Research will examine how various internal cellular characteristics (e.g., chloroplast position, DNA synthesis, lipid storage) correlate with marine dinoflagellate orientation during diel vertical migration in several environmental contexts. An understanding of these relationships will lead to the development of models that predict how growth and survival of photosynthetic populations vary in space and time. This variability will relate directly to the competitive capability of a species in a given water mass, to the development of patches at water convergences, and to the formation of dense layers within the water column.
