Webb11 okt. 2024 · Abstract. We introduce here a new index of diversity based on consideration of reasonable propositions that such an index should have in order to represent diversity. The behaviour of the index is compared with that of the Gini–Simpson diversity index, and is found to predict more realistic values of diversity for small communities, in ...
