Dataset underlying the publication: Seasonal dynamics of the standard test species <i>Lemna<i> sp. in outdoor microcosms</i></i>

The dataset covers photos of the microcosms used to collect the seasonal data for &lt;i&gt;Lemna&lt;i&gt; sp. populations; the results of the pre-experiments to study the appropriate nutrient levels for the growth of &lt;i&gt;Lemna&lt;i&gt; sp.; the experimental datasets covering experimental data over 2 consecutive years including biotic (biomass and numbers of fronds) and abiotic data from the aquatic habitat of &lt;i&gt;Lemna&lt;i&gt; sp. in the temperate climate region and the statistical regression results; and finally the weather data. The dynamics of biomass and numbers of fronds of &lt;i&gt;Lemna&lt;i&gt; sp. were studied using 100 small microcosms. Each microcosm was 45 cm in internal diameter, with a surface area of 0.174 m2, a height of 67 cm, a water depth of 56.5 cm and a volume of 26.56 L. The microcosms were buried in the ground to reduce fluctuation of water temperatures, and to provide conditions comparable to a small (edge-of-field) pond or ditch. Parameters monitored included biomass (fresh and dry weight), seasonal growth rates, relevant environmental parameters and weather data. This dataset includes the 2-year experimental biotic (biomass and numbers of fronds) and environmental data (water quality data, weather data).本数据集涵盖用于收集浮萍属（Lemna）种群季节性监测数据的微型生态系统（microcosms）实拍照片；用于探究浮萍属生长适宜营养水平的预实验结果；包含连续两年实验数据的核心实验数据集，其中涵盖温带气候区浮萍属水生生境的生物指标（生物量、叶状体数量）与非生物指标数据，以及对应的统计回归分析结果；此外还包含气象数据。 研究团队采用100个小型微型生态系统开展浮萍属生物量与叶状体数量动态变化的观测实验。 每个微型生态系统内径为45厘米，表面积0.174平方米，高度67厘米，水深56.5厘米，水体容积26.56升。 为降低水温波动并营造与小型田间边缘池塘或沟渠相近的生境条件，所有微型生态系统均埋设于地下。 本次实验监测的参数涵盖生物量（鲜重与干重）、季节性生长速率、相关环境参数与气象数据。 本数据集包含两年实验所得的生物指标数据（生物量、叶状体数量）与环境数据（水质数据、气象数据）。
