is a widespread and important marine primary producer. Time series provide critical information for identifying and understanding the factors that determine abundance patterns. Here, we present the results of analysis of a 16-yr hourly time series of at the Martha's Vineyard Coastal Observatory, obtained with an automated, in situ flow cytometer. We focus on understanding seasonal abundance patterns by examining relationships between cell division rate, loss rate, cellular properties (e.g., cell volume, phycoerythrin fluorescence), and environmental variables (e.g., temperature, light). We find that the drivers of cell division vary with season; cells are temperature-limited in winter and spring, but light-limited in the fall. Losses to the population also vary with season. Our results lead to testable hypotheses about ecophysiology and a working framework for understanding the seasonal controls of cell abundance in a temperate coastal system.
是一种分布广泛且重要的海洋初级生产者。时间序列为识别和理解决定丰度模式的因素提供了关键信息。在此，我们展示了在玛莎葡萄园海岸观测站对 进行的 16 年每小时时间序列分析的结果，该数据是通过自动原位流式细胞仪获得的。我们通过研究细胞分裂率、损失率、细胞特性（如细胞体积、藻红蛋白荧光）和环境变量（如温度、光照）之间的关系，着重于理解季节性丰度模式。我们发现细胞分裂的驱动因素随季节变化；细胞在冬季和春季受温度限制，但在秋季受光照限制。种群损失也随季节变化。我们的结果产生了关于 生态生理学的可检验假设以及一个用于理解温带沿海系统中 细胞丰度季节性控制的工作框架。
