Eukaryote Metabarcoding from Copper Mescosm Experiment

eDNA metabarcoding was performed to assess the effects of copper on the establishment of the benthic eukaryote community within a series of environmentally relevant copper contaminated freshwater mesocosms. The data is obtained from a recolonization experiment contained five treatments : control (C) and four sediment copper concentrations (very low (VL), low (L), high (H) and very high (VH)), each with four replicates. The data represents samples obtained on seven occasions subsequent to the experiment being established: 15, 31, 135, 161, 365, 407 and 497 days.

本研究采用环境DNA宏条形码技术（eDNA metabarcoding），旨在评估铜对一系列环境相关浓度铜污染淡水中型实验生态系统中底栖真核生物群落建立的影响。数据来源于一项再定植实验，该实验包含五种处理：对照（C）及四种沉积物铜浓度（极低（VL）、低（L）、高（H）和极高（VH）），每种处理设四个重复。数据代表实验建立后七个时间点采集的样本：15、31、135、161、365、407和497天。实验设计的详细信息可参考：Gardham, S., G.
