The steady-state relative population sizes of the several cell populations in Hydra attenuata were examined. In contrast to the constant average population size ratios between groups of animals, these ratios vary within limits between individual animals within a group. By maintaining animals on different feeding regimes (number of shrimp larvae ingested per day), the steady-state population size ratios were altered. The kinds of changes that occurred in these ratios suggest where controls may be operating to maintain the steady-state population sizes.
对细螅中几个细胞群体的稳态相对种群大小进行了研究。与动物群体之间恒定的平均种群大小比率不同，这些比率在一个群体内的个体动物之间在一定范围内变化。通过让动物维持不同的摄食方式（每天摄入的虾幼虫数量），稳态种群大小比率发生了改变。这些比率中发生的变化类型表明了控制可能在何处起作用以维持稳态种群大小。
