WebbSo if I write it over here, the diversity index for community two is going to be equal to one minus, I put a big parenthesis here, and we're going to have 925 over 1,000 squared, plus 40 over 1,000 squared, plus 35 over 1,000 squared. And if we simplify in a similar way, that's gonna be equal to one minus all these thousand squares.

The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community. Denoted as H, this index is calculated as: H = -Σpi * ln (pi) where: Σ: A Greek symbol that means “sum” ln: Natural log pi: The proportion of the entire community made up of species i Visa mer Suppose a biologist wants to measure the diversity of species in a local forest.
