The resultant diversity indices are a key feature of communities which can throw light on many aspects of conservation. Alternatively, species diversity indices have now been transposed to functional diversity measurements, and several new indices have been proposed (e.g., Mason et al.

It is assessed through a variety of indices, such as functional evenness and functional divergence that have been found to be better predictors of ecosystem functioning than species richness (Gagic et al., 2015). Simpson’s Index (D): Simpson’s index measures the probability that any two individuals drawn at random from an infinitely large community will belong to same species. Chron. Multiculturalism & Social Diversity in the Criminal Justice System. Species diversity in communities is a product of two variables: the number of species (richness) and their relative proportions (evenness). Diversity Powerpoint 1.
