WebSpecies coexistence is often ensured by niche separation. The ‘niche shift’ can follow from the competitive exclusion of one species from the part of ecological space where the niches overlap, or from coevolution of competing species, favoring in each species phenotypes differing from the phenotype of the competitor. WebAnother way by which niche differentiation can arise is via the previous elimination of species without realized niches. This asserts that at some point in the past, several …
