Abstract: Benthic molluscan fauna from litoral zones of Subarnarekha river, India was surveyed and ecologically interpreted based on their changing community structure in temporal and spatial scales during the period of July, 2012 – June, 2014. A total of 23 species of benthic molluscs belonging to 13 families and 11 genus were recorded from different sites of this river. Several biotic indices such as dominance, diversity, richness and evenness indices pertaining to community structure were worked out based on the seasonal population dynamics to assess the mode of seasonal variations of the studied community in changing ecological gradients. Spatial and temporal variabilties of benthic molluscan communityas recorded in this study, have revealed differential trends not only among different ecologically contrasting study sites (five) but among different seasons determined mostly by the fluctuating and unstable ecological gradients.
