Explain competitive release and Gause’s competitive exclusion principle.
Another evidence for the competition is competitive release, a phenomenon in which a species whose distribution is restricted to a small geographical area due to the presence of a competitively superior species, expands its distributional range when the competing species is experimentally removed. Gause’s competitive exclusion principle states that two closely related species competing for the same resources cannot exist together as the competitively inferior one will be eliminated, but this is true only when the resources are limiting and not otherwise. They have also pointed out that species facing competition might evolve mechanisms that promote co¬existence, rather than exclusion.
