competitive exclusion principle
competitive exclusion principle(exclusion principle, Gause principle) The principle that two or more resource-limited species, having identical patterns of resource use, cannot coexist in a stable environment: one species will be better adapted and will out-compete or otherwise eliminate the others. The concept was derived mathematically from the logistic equation by Lotka and Volterra (see Lotka–Volterra equations), working independently, and was first demonstrated experimentally by G. F.Gause in 1934, using two closely related species of Paramecium. When grown separately, both species populations showed normal S-shaped growth curves; when grown together, one species was eliminated.

competitive exclusion principle
competitive exclusion principle A rule, derived by G. F. Gause in 1934, stating that two species that occupy the same habitat cannot also occupy the same ecological niche. Any two species that occupy the same niche will compete with each other to the detriment of one of the species, which will thus be excluded.
