Species diversity is the measure of biological diversity observed in a particular ecological community indicating a number of species or species richness in an ecological community. Example – woodland forest comprising 4-5 different species of trees.
Species diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant).
Species diversity consists of species richness, the number of species, and species evenness, the relative abundance of species. While only 1.5 million species have been described, there are estimated …
Strictly speaking, 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,…
