The are some indexes (such as Shannon Index, Simpson's Index)
Explanation:
Ecologists developed some diversity indexes, which consider both the number and relative abundance of species within the community of concern, to express biodiversity.
Simpson's index (D) measures the probability that two individuals randomly selected from a sample will belong to the same category.
Another commonly used index, the Shannon Index (or the Shannon-Weiner Index), considers both species richness and evenness. In the absence of diversity, where one species is present, the value of this index is zero. The maximum values of this index can be Hmax= lnS where ln is the natural log (2.718) and S is the total number of species (species richness)..
