    • Abstract

       

      Homogeneity and diversity of the intertidal polychaetes in the Vasishta Godavari estuary are discussed basing on the collections made at six fixed stations during October 1976 and January 1978. Matrix and rarefaction methods are adopted for arriving at homogeneity and diversity respectively. Homogeneity varied along with the salinity structure in the estuary; high percentage of affinity was observed during the recovery and summer periods while affinity was relatively low during annual freshwater flood period. The factors generally controlling the diversity and the reasons for high polychaete diversity in this estuary are discussed.
