Taxonomically known number of species
WebA has the same number of species as community B but the relative abundances are more even, so by a heterogeneity measure A is more diverse thanB. Community C has the same abundance pattern as B but has more species, so it is more diverse than B. (c) Evenness: when all species have equal abundances in the community, evenness is maximal. Figure … Webthis area, because one species is common and the other two are relatively rare there is less diversity than there would be if there were two equally frequent species.
