Based on ISSR fingerprints ,total no.of amplicon obtained and sum of amplicon of each strains were used as input data to study the diversity within the species.

Shannon and Simpson indices are used for understanding the diversity within the sample.
More number of species means more richness
Unequal abundance means less diversity (e.g. some species are too dominant, some are rare), equal abundance means more diveristy.
Both the indices have their own advantages, for e.g. Simpson is a dominant index while Shannon is a random and considers both the abundance and equivalence of abundance.
Nonetheless, more the SImpson value, less will be diversity, generally ranges from 0 to 1. Inverse is true for Shannon.
