Relative species abundance

Relative species abundance is a component of biodiversity and is a measure of how common or rare a species is relative to other species in a defined location or community.^[1] Relative abundance is the percent composition of an organism of a particular kind relative to the total number of organisms in the area.^{[citation needed]} Relative species abundances tend to conform to specific patterns that are among the best-known and most-studied patterns in macroecology. Different populations in a community exist in relative proportions; this idea is known as relative abundance.
