The displaced species may become locally extinct, by either migration or death, or it may adapt to a sufficiently distinct niche within the environment so that it continues to coexist noncompetitively with the displacing species. This leads either to the extinction of the weaker competitor or to an evolutionary or behavioral shift toward a different ecological niche. Competitive exclusion is the principle of nature. The competitive exclusions principle says that two species cannot exist together if they compete for the same resources. In ecology, the competitive exclusion principle, sometimes referred to as Gause's law of competitive exclusion or just Gause's law, is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are constant.
