Abstract
ABSTRACTAcanthamoeba rhysodes has been found to be a predominant intertidal benthic gymnamoeba in the mangrove ecosystem of Sundarbans of lower deltaic Bengal, facing the Bay. The sampling zones under study were the highest high tide regions, with characteristic mangrove litter‐soil, inundated twice per month during the highest ebb of spring tide. Population abundance of this species, both in its trophic and cystic forms in the three distinct seasonal periods of pre‐monsoon (March to June), monsoon (July to October), and post‐monsoon (November to February) has been surveyed for over two years. These seasonal periods affect the physico‐chemical parameters of the habitat substrata, including temperature, pH, and salinity. It has been found that the overall number of organisms per gram of soil attains peak value during the monsoon period. This value comes down in post‐monsoon samples and is the least in pre‐monsoon ones.
