Hourly temperature, environmental parameter and Daphnia magna phenotypic and genetic change in mesocosms with manipulated experimental parameters, 2017-2019

This dataset contains information about hourly temperature variation, phenotypic and genetic change, and change in environmental parameters in a two-year mesocosm study designed to tease apart the impact that phenotypic plasticity and genetic diversity have on rate of adaptation to experimental heatwaves. All data were collected between 2017 and 2019. Thermal data was collected continuously using data loggers. The frequency of natural heatwaves was manipulated using a programmable aquatic mesocosm facility using data collected from real heatwaves from 2006. Phenotypic evolution was tracked using intermittent common garden life-history studies while changes in clone frequency were determined using microsatellite markers to track changes in clone frequency in manipulated populations over two years. Experimental data on zooplankton community dynamics were monitored using intermittent depth integrated sampling of communities in each mesocosm over two years. The work was supported by the Natural Environment Research Council (Grant NE/N016017/1).

本数据集源自一项为期两年的中型实验生态系统（mesocosm）研究，该研究旨在厘清表型可塑性（phenotypic plasticity）与遗传多样性对实验性热浪适应速率的影响，涵盖逐小时温度变化、表型与遗传变化以及环境参数变化的相关信息。所有数据采集于2017至2019年期间。温度数据通过数据记录仪（data loggers）连续采集获得。本研究依托可编程水生中型实验生态系统装置，基于2006年实测热浪数据，对自然热浪的发生频率进行人工调控。表型演化通过间歇性同质园生活史实验进行追踪；而克隆频率的变化则借助微卫星标记（microsatellite markers）进行测定，以追踪两年间人工调控种群内的克隆频率动态变化。浮游动物群落动态的实验数据，则通过两年间对每个中型实验生态系统内的群落开展间歇性深度整合采样进行监测。本研究得到自然环境研究委员会（Natural Environment Research Council，资助号NE/N016017/1）的资助。
