Macrozoobenthos abundance and biomass from river rapids in Eastern Fennoscandia

This dataset contains sample-level macrozoobenthos abundance (ind./m²) and wet weight biomass (g/m²) from 535 samples collected at 209 rapids sites across Eastern Fennoscandia (Republic of Karelia and Murmansk Oblast, Russia) between 1998 and 2024. Data are provided at the resolution of major taxonomic groups. Total abundance and biomass per sample are also provided, along with adjusted values after outlier removal and winsorization (as used in the associated publication). Site characteristics and metadata are included. Associated publication: Baryshev I.A. "Estimating Macrozoobenthos Abundance and Biomass in River Rapids: Accuracy Analysis via Randomization" (L&O: Methods).本数据集包含1998年至2024年间，在芬诺斯堪的亚东部地区（俄罗斯卡累利阿共和国与摩尔曼斯克州）209处急流生境采样点采集的535份样本数据，涵盖样本级大型底栖无脊椎动物（macrozoobenthos）个体丰度（单位：ind./m²）与湿重生物量（单位：g/m²）记录。数据以主要分类类群为分辨率粒度提供，同时提供每份样本的总丰度与总生物量，以及关联研究中采用异常值剔除与温莎标准化（Winsorization）处理后的校正数值。此外，数据集还包含采样点特征信息与元数据。 关联出版物：Baryshev I.A.《河流急流生境大型底栖无脊椎动物丰度与生物量估算：基于随机化方法的精度分析》，发表于《L&O: Methods》。
