competion exclusion.competitive exclusion principle, sometimes referred to as Gause's law of competitive exclusion or just Gause's law, is a proposition that states that two speciescompeting for the same resource
cannot coexist at constant population values, if other ecological
factors remain constant. When one species has even the slightest
advantage or edge over another then the one with the advantage will
dominate in the long term. One of the two competitors will always
overcome the other, leading to either the extinction of this competitor
or an evolutionary or behavioral shift toward a different ecological niche. The principle has been paraphrased into the maxim "complete competitors cannot coexist"
