Species diversity and evenness
WebHowever, species richness can be a misleading indicator of diversity as it does not take into account the number of individuals of each species; Species evenness is a measure of the relative abundance of the different species within a given area. An area in which all the species have similar abundances will have a greater species evenness WebDiversity has variously been related to other attributes of the community or properties of the environment, among which time, spatial heterogeneity, stability, primary production, …

WebBiological diversity comprises both species richness, i.e., the number of species in a community, and evenness, measuring how similar species are in their abundances. The relationship between species richness and evenness (RRE) across communities remains, however, a controversial issue in ecology because no consistent pattern has been reported. WebMar 29, 2024 · The term “evenness” simply refers to how similar the abundances of different species are in the community. Denoted as EH, this index is calculated as: EH = H / ln(S) where: H: The Shannon Diversity Index S: The total number of unique species This value ranges from 0 to 1 where 1 indicates complete evenness.
Webspecies. Evenness measures should measure the equality of abundances in the community: maximum evenness (1.0) arising when all species are equally abundant, and the more relative abundances of species differ the lower the evenness is. In accordance with Peterson (1975) evenness is not restricted merely as diversity divided by
