Describe how to measure species richness and species evenness. (supplemental resource?

species richness is the total number of species present if there are 4 species present and 5 of each then the species richness is 4 as there is 4 types of species while the species evenness is 5 a species eveness is the relative abundance of each species.


Why is species richness more important than abundance?

species richness is related to species diversity. It refers to the number of different species present in an environment. species evenness refers to how close in numbers each species in an environment are. For example an environment with three species A, B, C A has 56 B has 54 C has 55 This environment is low in species richness but high in evenness.


What is dominance index?
