Observed environmental range.

Distributions of environmental variables at Anholt and at Ven for three separate size classes of Mnemiopsis leidyi. Irradiance was only measured during daytime. The box represents 50% of all observations, with the solid line representing the median, the whiskers 10th and 90th percentile, and the dots the 5th and 95th percentile. Axes correspond to minimum and maximum of measured variables at the respective location. S = Small, M = Medium, L = Large. Small and medium individuals in Kattegat migrated.

针对三类不同尺寸类群的侧腕栉水母（Mnemiopsis leidyi），本数据集统计了安霍尔特岛（Anholt）与文岛（Ven）两处的环境变量分布特征。辐照度仅在日间开展测量。箱线图的箱体涵盖全部观测值的50%区间，其中实线代表中位数，须线对应10%与90%分位数，散点标记则对应5%与95%分位数。坐标轴对应各采样地点实测环境变量的取值上下限范围。其中S代表小型个体，M代表中型个体，L代表大型个体。卡特加特海峡（Kattegat）内的小型与中型侧腕栉水母存在洄游行为。
