โœฆ Synopsis


The logistic equation has been used as the basis of two distinct models of population dynamics, a resource limited model and an equilibrium model. It is argued that although the two models are very different, the distinction between them has been obscured by the use of the same terminology for the parameters of both. It is further argued that the simple equilibrium model developed from the logistic equation has inconsistencies which make it untenable as a population model.

1. The renewal rate of resources exploited by a population influences carrying capacity and competitive interaction. A model of resource renewal is proposed where P is the fraction of the resource exploited at any given time, p the fraction exploited per day, and a the fraction remaining per day. At
