Field estimates of selection on offspring size in Watersipora subtorquata. Treatment refers to the environment in which colonies grew (1 = no competition, 2 = intermediate competition, 3 = intense competition), column A is standardised offspring size, column Z is standardised zooid size, column S is standardised colony senescence. Fitness is the sum of reproduction across the entire experimental period.本数据集为平截膜孔苔虫（Watersipora subtorquata）后代体型选择压力的野外估算结果。其中处理变量（Treatment）指代群体生长所处的环境条件：1代表无竞争环境，2代表中等竞争环境，3代表高强度竞争环境；A列为标准化后代体型，Z列为标准化个员体型，S列为标准化群体衰老程度。适合度（Fitness）为整个实验周期内的总繁殖量。
