Biodiversity of the rotifers (Rotifera: Eurotatoria) of Nagaland, northeast India: Composition and ecosystem diversity


Author(s): BK Sharma, Kensibo and Sumita Sharma

Abstract: Northeast India (NEI), an interesting ‘hot-spot’ for metazoan diversity, is known for diverse aquatic habitats. This study is an attempt to document Rotifera diversity of the hill state of Nagaland of NEI vis-à-vis small lentic ecosystems. A total of 150 species belonging to 37 genera and 19 families observed in our collections comprise ~36.0 % of species of the Phylum known from India and thus highlight ecosystem diversity of small water bodies. Two species are new records to India and 38 species are new to Nagaland. The globally interesting rotifers (14.7%) include four Australasian, six Oriental, nine palaeotropical, and one each of Palearctic, Indo-Chinese and cosmo (sub.) tropical species. Lecanidae > Brachionidae > Lepadellidae collectively comprise ~61.0% of the recorded species and Trichocercidae > Testudinellidae are other notable families. The speciose nature of ‘tropic-centered’ genus Lecane, the collective importance of Lepdella > Brachionus = Trichocerca, and high richness of cosmpolitan species are noteworthy.
