Time series of T. suecica densities under fluctuating temperatures experiment from May 2023 to Aug 2023

This dataset includes the densities (count/mL) of the alga Tetraselmis suecica (LB 2286) cultures grown from a UTEX sample. The counts were obtained using a Beckman Coulter Z2 Particle Counter in the lab over a five-day period under different experimental temperature regimes. The experiment took place between 2023-05-23 and 2023-08-18. The goal of the experiment was to determine how mean temperature and temperature fluctuation frequency affected the growth rate of T. suecica. By comparing the growth rate of T. suecica under constant vs. variable temperatures, one can determine the historical or legacy effects of past temperature variation on subsequent organismal performance. These experiments were conducted by members of the Brian Helmuth Lab at Northeastern University.本数据集包含源自UTEX保藏样品的盐生四鞭藻（Tetraselmis suecica，菌株编号LB 2286）培养液的细胞密度，单位为个/毫升。细胞计数于实验室环境中完成，采用贝克曼库尔特Z2颗粒计数器（Beckman Coulter Z2 Particle Counter），在为期5天的观测周期内，针对不同实验温度调控方案下的培养体系进行计数。本实验开展于2023年5月23日至2023年8月18日期间，研究目标为探明平均温度与温度波动频率对盐生四鞭藻生长速率的影响。通过对比该藻株在恒温与变温条件下的生长速率，可揭示过往温度波动对后续生物体生存表现的历史遗留效应。本系列实验由美国东北大学（Northeastern University）布莱恩·赫尔穆斯实验室（Brian Helmuth Lab）的研究人员执行完成。
