Abstract:
The concept of segregation has received less attention in ecology. Species diversity is a concept that includes the number of species (the total number of possible species) in the community, their abundance, and the individuals who are divided among the species, for which biodiversity is generally considered in three dimensions: within communities (α-diversity), between or among communities (β-diversity), and in the total dataset (γ-diversity). Recently, Shamia proposed using an improved generalized diversity index, which includes special cases of MacArthur's and Hill’s indices. Such an index is easy to interpret when all species have equal even abundances resulting in an equivalent number to refer to the output in the community. index, when community weights are unequal relative abundances, has been applied to real data for comparing the index's performance under the segregation concept. Such measure for different sites gives meaningful results of multiplicative partitioning.
