in order to understand the nature of the ecologists investigationwe may think of the density-dependent effects on growth parameters as the signal ecologists are trying to isolate and interpretone that tends to make the population increase from relatively low values or decrease from relatively high oneswhile the density-independent effects act to produce noise in the population dynamics

为了理解生态学家调查的本质，我们可以把对生长参数的密度依赖效应看作是生态学家试图分离和解释的信号，这种信号往往会使种群从相对较低的值增加或从相对较高的值减少，而密度独立效应则在种群动态中产生噪声
