“Species Diversity and Taxonomic Assessment of Cosmarium from a Freshwater Habitat: Aner Dam”.

Abstract The present study investigates the species diversity and taxonomic characteristics of the desmid Genus Cosmarium from the freshwater habitat of Aner Dam, located in Shirpur Taluka, Dhule District Maharashtra, India. A total of six Cosmarium species were identified and documented: Cosmarium lundellii, Cosmarium pardalis, Cosmarium portianum, Cosmarium pseudoconnatum, Cosmarium pseudotaxichondrum, and Cosmarium spinuliferum. These taxa were studied through detailed morphological observation using microphotography, focusing on key diagnostic features such as cell shape, dimensions, wall ornamentation, and isthmus structure. The findings highlight a notable species richness and microalgal diversity within the dam's phytoplankton community, underscoring its ecological importance. The occurrence of both common and relatively rare Cosmarium taxa in the region also suggests a favourable environment for desmid proliferation, potentially influenced by specific physico-chemical conditions of the water body. This study contributes to the growing body of taxonomic knowledge of freshwater desmids in India and provides baseline data for future ecological and conservation assessments of microalgal biodiversity.
