WebSpecies diversity is a measure of community complexity. It is a function of both the number of different species in the community (species richness) and their relative abundances (species evenness). Larger numbers of species and more even abundances of species lead to higher species diversity. For example: A forest community with 20 20 WebGenetic diversity within species is important to provide flexibility of species to adapt to particular habitats over long spans of time.
