Abstract

Mortality, growth and birth rates cannot vary independently in stable populations, environmental change of one variable must be accompanied by compensatory variation of another. Ecological compensation is recognized if the stable populations are genetically identical. Ecological compensation, if it operates, constrains the direction of evolutionary change, and predictions that ignore it may be in error.

摘要

在稳定种群中，死亡率、增长率和出生率不能独立变化，一个变量的环境变化必然伴随着另一个变量的补偿性变化。如果稳定种群在基因上是相同的，那么生态补偿就会被识别出来。生态补偿如果起作用，就会限制进化变化的方向，而忽略它的预测可能会出错。
