the extinction of one species by another species in the same area through competition.
The (local) extinction of a population, which is an inferior competitor under prevailing circumstances. Because of its inferiority in competing with other species for resources, the species excluded cannot become permanently reestablished.
In ecology, the competitive exclusion principle (also known as Gause's principle) states that no two species can occupy exactly the same fundamental niche indefinitely in a habitat where they are competing for the same essential resource, and that one species will crowd out the other.
Two species cannot share a niche for long. One species will become ext nct or change to occupy a slightly different niche.
The elimination from an area or habitat of one species by another through interspecific competition.
Competition between species that is so intense that one species completely eliminates the second species from the area.
Situation where no two competitively interacting species can occupy exactly the same fundamental niche indefinitely because of resource limitations. The outcome of this process is the local extinction the species that is a poorer competitor.
