Species richness is a measurement of diversity that indicates the number of different species or different types of microorganisms that are present in a sample. The SRD determination of microorganisms in a particular microbial functional group is an index of the variety of microbes in that functional group. This index is derived from a standard microbial ecology formula that weighs the variety of species within a functional group from a normalized analysis of species richness against the total number of microorganisms associated with that functional group.
