Abstract

A preliminary study was carried out in Pobitora Wildlife Sanctuary, during December 2023 to assess the testate amoeba diversity. The sanctuary has wet mixed deciduous forest, grassland and marshy areas and is situated at the Brahmaputra floodplain region. During this study, thirty seven species of testate amoebae were recorded which belonged to nine families and twelve genus. Twenty nine species belongs to phylum Cercozoa; Genus Centropyxis Stein 1857, Euglypha Dujardin 1841, Difflugia Leclerc 1815, Arcella Ehrenberg 1830 and Trinema Dujardin 1841 are the dominant while family Centropyxidae has highest number of species in the study area. High abundance and species richness of testate amoebae indicates the resilient nature of the ecosystem in the forest. This sanctuary has gained importance due to its ability to serve as an ideal habitat for the Greater One Horned Rhinoceros, a vulnerable species on the IUCN Red List. The increasing contest for space and resources between this mega herbivore and humans are causing habitat destruction in the area; while the recurrence flood also enhances the habitat destruction process. This Anthropocene driven habitat has a huge impact on community structure of the animals including the microbial world. The testate amoeba community structure differs with its biotopes, indicating its capability to serve as a bioindicators. The incorporation of the study of testate amoeba diversity can serve as a potent tool to assess the change in the forests (habitats), formulate steps to conserve our forests and assess their ecological health.
