WebThe diversity of species in an area depends on both the number of species observed (species richness) and their total numbers, and evenness refers to the relative abundance of species. Evenness is high if all species have similar distribution (i.e., similar population density) (Baker and Savage, 2008). WebMathematically, we can distill species richness and species evenness of a habitat into a single measure of overall diversity using the following equation. (2.2.1) D = ( p 1 − p 1) ( p 2 − p 2) ( p 3 − p 3) … ( p n − n) where D is a measure of the total diversity of the ecosystem, and pn is the proportion of species n.
WebThe relative abundance definition in chemistry is the percentage of a particular isotope that occurs in nature.
