Web9 de feb. de 2024 · Because species richness, the Shannon index and the Gini–Simpson index do not measure the same quantities, justifying the choice of one of them to represent diversity is particularly difficult. A second problem is that the Shannon and Gini–Simpson indices behave in ways that do not make sense for a metric of diversity.
