Web29 de mar. de 2024 · The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community.

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.
