Please clear the distinction between the two terms: 'abundance' and 'density' in this case. If possible attach research papers on determination of these two.
Relative species abundance is calculated by dividing the number of species from one group by the total number of species from all groups.
Abundance is an ecological concept referring to the relative representation of a species in a particular ecosystem. It is usually measured as the large number of individuals found per sample. How species abundances are distributed within an ecosystem is referred to as relative species abundances.
Population density is a measurement of population size per unit area, i.e., population size divided by total land area.
