relative adundance
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.
Biodiversity is the measure of the number of species living within an ecosystem.

Species diversity is the number of different species in a particular area (species richness) weighted by some measure of abundance such as number of individuals or biomass. However, it is common for conservation biologists to speak of species diversity even when they are actually referring to species richness.
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.

Dominance index = 1-J where J is the evenness of relative diversity (H'/H max) where absolute evenness = 1. It is used to compare the dominance of the same species in different ecosystems.
Depends on whether you want to measure the length (drive along it), its width (surveying equipment or large tape measure), depth of tarmac or concrete (drill samples), evenness, water dispersal or any of the host of other measures.
The opposite would be symmetry, or evenness.

Biodiversity is the measure of the number of species living within an ecosystem.
Competition coefficients measure the effect of one species on another competing species.
stability, balance, symmetry, steadiness, evenness, equipoise
Species diversity.
Synonyms could include balance, evenness, or regularity.
