WebThe diversity function can find the total (or gamma) diversity of pooled communities with argument groups. The average alpha diversity can be found as the mean of diversities by the same groups, and their difference or ratio is an estimate of beta diversity (see Examples).

WebThe Shannon Diversity Index, also known as the Shannon-Wiener Index, is another way to measure an area's biodiversity. This index uses the formula for entropy created by Claude Shannon and uses it in the context of biodiversity.
