Abstract
Models of competition in divided or heterogeneous environments are reviewed. A model of competition in a divided environment is presented. The competition coefficients, .alpha., are reduced by a term, .theta., which measures the amount of overlap between species. Actual values of .theta. are presented for 2 Drosophila communities. .theta. depends on the degree of aggregation of the competing species and on their densities. The outcome of competition in a divided environment must be density dependent. Low values of .theta. improve the stability of a multi-species community and allow more species to coexist.This publication has 9 references indexed in Scilit:
