http://agtr.ilri.cgiar.org/quantitative-methods/measuring-genetic-diversity-molecular-data WebA diversity index is a measure of the “diversity” of an area. Diversity could be measured in terms of the numbers of species (or higher taxonomic groupings like genera, families, phyla), or other metrics such as number of haplotypes if you’re interested in genetic diversity, or number of functional groups for studies of functional diversity.
