Abstract:
... The present analysis of alpha diversity of Rotifera of the floodplain wetlands of Barak valley, south Assam, northeast India (NEI) reveals 170 species, belonging to 39 genera and 19 families, with three species new to the Indian sub-region and two species new to Assam state. The rich and diverse rotifer assemblages comprise ~70%, ~57% and ~39% of total species of the Phylum known till date from As ...
... The study aims to ascertain the hypothesis on the rich rotifer biodiversity of the floodplain lakes (beels) of the Brahmaputra river basin and to use these metazoans to assess trophic status or to characterize habitat variations of wetlands. The plankton samples collected from four beels of lower Assam revealed 160 Rotifera species belonging to 35 genera and 19 families. The richness is of biodive ...

Abstract:
... The zooplankton assemblage of selected wetlands of Assam, India was assessed to deduce the structural variation in the context of water quality parameters. A two year study between 2012 and 2014 comprising of 530 samples from the five wetlands revealed the presence of 46 taxa, 26 Rotifera, 15 Cladocera, 4 Copepoda and 1 Ostracoda, in varying density. The rotifers dominated in terms of abundance (4 ...

Abstract:
... Plankton samples collected from freshwater lentic ecosystems of south Andaman, India, revealed 70 species of Rotifera belonging to 25 genera and 16 families. The reports of Australasian Lecane batillifer, Oriental endemic Lecane bulla diabolica and three Paleotropical species, and 68 new records of Eurotatoria from Andaman and Nicobar Islands contribute to biodiversity and biogeography of the Indi ...

Abstract:
... Keibul Lamjao National Park (KLNP), a floating park in Loktak Lake, Manipur (India) was studied from Winter (WIN) to Post Monsoon (POM) for its zooplankton composition and some selected water parameters. The resultant data were subjected to multivariate techniques–Principal Component Analysis (PCA) and Canonical Correspondence Analysis (CCA). Analyses of water parameters with PCA revealed that the ...

Abstract:
... Old Fort Lake, a small (1.6 ha), shallow, and recreational water body in Delhi (India) was studied through monthly surveys in two consecutive years (January, 2000-December, 2001). Precipitation is the major source of water for this closed basin lake. In addition, ground water is used for replenishing the lake regularly. This alkaline, hyposaline hard water lake contains very high ionic concentrati ...

Abstract:
... Rotifera is a Phylum of primary freshwater Metazoa containing two major groups: the heterogonic Monogononta and the exclusively parthenogenetic Bdelloidea. Monogononta contains 1,570 species-level taxa, of which a majority (1,488) are free-living fresh or inland water taxa. Bdelloidea contains 461 “species,” only one of which is marine, but with many limnoterrestrial representatives or animals of ...
... The present paper cites results of zooplankton composition that carried out in the six water bodies of Dharwad district during September–November 2004 (post monsoon) and February–April 2005 (pre monsoon). Comparison of the obtained results with those of earlier investigations performed during 1978–1979 showed that changes have occurred in the interval. The total zooplankton composition is signific ...
