ON CARRYING-CAPACITY CONSTRUCTION, METAPOPULATIONS AND DENSITY-DEPENDENT MORTALITY

摘要

We present a mathematical model for competition between species that includes variable carrying capacity within the framework of niche construction. We make use the classical Lotka-Volterra system for species competition and introduce a new variable which contains the dynamics of the constructed niche. The paper illustrates that the total available patches at equilibrium always exceeds the constructed niche at equilibrium in the absence of species.
