Multi-decadal improvements in the ecological quality of European rivers are not consistently reflected in biodiversity metrics

The datasets here were used to examine relationships between various community metrics (e.g., abundance, richness), biomonitoring indices, and ecological quality across European riverine invertebrate communities during 1992-2019. Here, we provide two datasets used in the publication by Sinclair et al. titled "Multi-decadal improvements in the ecological quality of European rivers are not consistently reflected in biodiversity metrics". Each dataset is provided as a separate Excel document. The first dataset ("Community metrics, biomonitoring indices, and EQRs") provides the data for each site and year used in the majority of the analyses. The second dataset ("EQCs") provides the additional data used to model temporal changes in Ecological Quality Classes depicted in Fig. 2 and Fig. 4. A summary and explanation of each variable in each dataset is provided in the "Info" tab. Further information on how values were calculated (and transformed if necessary) is provided in either the Info tab or the methods and supporting information of the associated article.

本数据集旨在探究1992年至2019年间欧洲河流无脊椎动物群落的各类群落指标（如丰度、物种丰富度）、生物监测指数与生态质量之间的关联。本次提供的两份数据集来自Sinclair等人发表的题为《欧洲河流生态质量的数十年改善并未在生物多样性指标中得到一致体现》的研究论文。每份数据集均以独立的Excel文档形式提供。第一份数据集（「群落指标、生物监测指数与生态质量比（EQRs）」）包含了大部分分析中所用的各采样点及对应年份的数据。第二份数据集（「生态质量等级（EQCs）」）包含了用于建模图2与图4中所示生态质量等级时序变化的补充数据。各数据集内所有变量的汇总说明与解释均位于「Info」标签中。关于变量值的计算方式（必要时还包括数据转换方法）的更多信息，可查阅「Info」标签或相关论文的方法学部分与补充材料。
