Simpsons biodiversity index formula

WebbSimpson’s Index of Diversity (SID). The formula is: SID = 1 – D where D is a measure of diversity, computed as follows: € D= n 1(n 1−1)+n 2(n 2−1)+n 3(n 3−1)+…n k(n k−1) … WebbSimpson's index of diversity (1 - D) - The probability that two randomly selected individuals in a community belong to different categories (e.g., species).

WebbSimpson'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.

WebbSimpson’s Diversity Index = 98 x (98 – 1) [2x (2-1)] + [2x (2-1)] + [1x (1-1)] + [93x (93-1)] = 1.11 From this it can be seen that ecosystem 1 has the highest index of diversity. The larger then Simpson’s index the more diverse. Increasing diversity tends to suggest more stable ecosystems with more connections within them.
