Pielous evenness is an index that measures diversity along with species richness. A review with special relevance to aquatic ecosystems. Gerhardt, ; Werneck et al. In Ecological diversity in theory and practice edited by J. Botanical Journal of the Linnean Society On the diversity of reptile and amphibian species in a bornean rain forest.
The nonconcept of species diversity: Additionally, depending on the weight the indices give to each component, an index may indicate that community A is more diversified than community B while a second index may indicate the contrary.
