AxIOM: Amphipod crustaceans from insular Posidonia oceanica seagrass meadows

AxIOM is a sample-based dataset (n = 187 samples) documenting occurrences of amphipod crustaceans associated to Posidonia oceanica seagrass meadows from Mediterranean Islands (Corsica, Sardinia). In total, it contains 10720 records of specimens belonging to 72 species spanning 29 families. Samples were collected over different periods 3 consecutive years, both during the day and during the night. A nested hierarchical sampling design was set up, and multiple sampling methods were combined to ensure a holistic view of the taxocenosis. The dataset package is composed of two data files: one describing sampling events, and the other reporting occurrence data of amphipod crustaceans.AxIOM是一个基于样本的数据集（样本量n=187），记录了地中海岛屿（科西嘉岛、撒丁岛）范围内与波西多尼亚海草（Posidonia oceanica）床共生的端足类甲壳动物（amphipod crustaceans）的出现记录。该数据集总计包含10720条标本记录，隶属于29科、72个物种。样本采集工作在连续3年的多个时段开展，涵盖白昼与夜间两个时段。研究采用嵌套分层抽样设计，并结合多种采样方法，以全面呈现该类群的分类群落（taxocenosis）组成。本数据集套件包含两个数据文件：其一用于描述采样事件的详细信息，其二用于记录端足类甲壳动物的出现数据。
