Species richness is the number of different species represented in an ecological community, landscape or region. [1] Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions .
As of 2008, about 90% of global wealth is distributed in North America, Europe, and "rich Asia-Pacific" countries, [39] and in 2008, 1% of adults were estimated to hold 40% of world wealth, a number which falls to 32% when adjusted for purchasing power parity. [40]

Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first.
It is sometimes summarized by the adage or platitude "the rich get richer and the poor get poorer". [1] [2] Also termed the "Matthew effect of accumulated advantage", taking its name from the Parable of the Talents in the biblical Gospel of Matthew, it was coined by sociologists Robert K.

Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness is the relative number of individuals of each species in a given area. [1]
