Principle of competitive exclusion and drosophila

Research output: Contribution to journalArticle

Abstract

THE Volterra-Gause equations1 - the mathematical formulation of the principle of competitive exclusion2 - are illusr rid="illus1" where r1 is the intrinsic rate of increase of species 1, N1 is its population size, and K1 is the expected value of N1 in single species culture. The constants α and β, the coefficients of competition, denote the relative effect of the abundance of one species on the population growth rate of the other. These relationships imply that for a stable competitive equilibrium to obtain it is necessary that illusr rid="illus2".
