Dataset underlying the publication Seasonal dynamics of the macrophyte test species Myriophyllum spicatum over two years in experimental ditches for population modelling application in risk assessment

The dataset covers biotic and abiotic data from the aquatic habitat of a population of the sediment-rooted macrophyte <i>Myriophyllum spicatum</i> in the temperate climate region (The Netherlands). The growth of M. spicatum was monitored in 0.2025 m2 plant baskets installed in an experimental ditch. Parameters monitored included biomass (fresh and dry weight), shoot length, seasonal short-term growth rates of shoots, relevant environmental parameters and weather data. This dataset includes the 2-year experimental biotic (macrophyte biomass and growth data) and environmental data (water quality data, sediment data). A second file includes the statistical data. A third file includes the weather data.

本数据集涵盖了温带气候区域（荷兰）某种群的扎根底泥大型水生植物（macrophyte）穗状狐尾藻（Myriophyllum spicatum）的水生栖息地生物与非生物数据。研究人员通过安装于实验沟渠内的0.2025平方米植物种植篮，对穗状狐尾藻的生长状况进行了监测。所监测的参数包括生物量（鲜重与干重）、茎枝长度、植株茎枝的季节性短期生长速率，以及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数据（大型水生植物生物量与生长数据）与环境数据（水质数据、底泥数据）。其中第二个文件包含统计分析数据，第三个文件包含气象数据。
