amphipoda_dataset.xls

Dataset concerning the abundance of sampled amphipods in three <i>Posidonia oceanica</i> meadows from the central Tyrrhenian Sea (Mediterranean Sea), characterised by different habitat features. Alongside the abundance, the dataset contains a field named BS (body size, taken as the maximum body length measured from anterior margin of the head to the posterior end of the telson, in mm) representing the average maximum length between male and female specimens.

本数据集收录了地中海第勒尼安海中部三处生境特征各异的大洋海神草（Posidonia oceanica）海床中采集的端足类（amphipods）丰度数据。除丰度信息外，数据集还包含名为BS的字段，该字段对应体大小（body size）指标：其以头部前缘至尾节后缘所测得的最大体长为定义标准，单位为毫米，取值为雌雄标本的平均最大体长。
