WebA simple biodiversity index is calculated as follows: number of species in the area ÷ total number of individuals in the area = biodiversity index.

WebSimpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. As species richness and evenness increase, so diversity increases. The value of D ranges between 0 and 1. With this index, 1 represents infinite diversity and 0, no diversity. eastchester rd labcorp
