This illustrates the "competitive exclusion principle," which theorizes that no two species can occupy (Gause, 1934) the same niche at the same time in a particular locale if resources are limited.

Low overlap (r near to zero) means that the species can differ greatly in fitness and still coexist with each other, whereas large overlap (r near to one) means fitnesses must be nearly equal for coexistence to occur (Fig. 2).
