Abstract : With respect to species diversity in different habitats of any community, there is a vivid gradient in species richness and abundance with the highest in the tropics and lowest in the poles. Use of various cardinal information statistic indices like S-W alpha diversity, abundance, evenness, similarity index and dominance for quantifying the species diversity both within and between the habitats carries significant value to depict the survival status of a particular species in a community. Ant population expected to be well diversified in terms of species richness and abundance has been sampled from northern & Southern zones of Ranchi city situated at latitude and longitude of 8802’N – 2303’E & 22055’S – 88010’E, having tropical characteristic. The results of application of these species diversity indices as information statistics tools for different ant species sampled have been discussed in this paper which can explain the causes of ant species diversity in this area in relation to other biotic and abiotic factors.
