Faunal diversity of zooplankton in the selected wetlands of Nagaland, North-East India
Keywords:Zooplankton, Diversity, Wetlands, Nagaland, North-East India.
The study aims to assess the faunal diversity of zooplankton importance base on our plankton collections from three selected wetland of Nagaland (North East-India). Our collection from Madladijam, Bolfangdisa and Noune wetlands revealed biodiverse zooplankton assemblage with a report of 181 species spread over 79 genera and 34 families, belonging to five groups of zooplankton. Rotifera followed by Cladocera largely contribute to zooplankton richness while Rhizopoda, Copepoda and Ostracoda are other components. Our study reveals 32 species new records from Nagaland State and 2 species from North East-India, besides, 50 species of rotifers has been recently added as new records from the State. Total zooplankton richness ranged between 109-160 (138±22) species and percentage similarity between wetlands shows high similarities, Noune and Madladijam is 71.1%; Noune and Bolfangdisa is 73.6% and similarity between Madladijam and Bolfangdisa wetland is 83.4%. The study revealed several biogeographically interesting elements. The biodiversity and biogeographically importance as recorded is attributed to ecological heterogeneity of the sampled wetlands.
