| Zooplankton are among the most important microscopic animals in aquatic ecosystems, playing a crucial role in maintaining water quality and serving as a vital link in the food chain. Water quality parameters play a crucial role in regulating the abundance and diversity of zooplankton. This study was conducted over a period of three months at three different locations within the Ranganathittu Bird Sanctuary (RBS), Karnataka, India, to assess the diversity and abundance of zooplankton. Key physicochemical parameters including water and atmospheric temperature, electrical conductivity, pH, turbidity, total dissolved solids, carbon dioxide, biological oxygen demand, dissolved oxygen, phosphate, and nitrite were analyzed. The zooplankton community was represented by four major taxa: Copepoda, Cladocera, Rotifera, and Ostracoda, comprising a total of 34 species. The analysis revealed a total of 34 zooplankton species across all sampling sites. Among these, Cladocera emerged as the dominant and most species-rich taxon, represented by 14 species, followed by Copepoda (10 species), Rotifera (8 species), and Ostracoda (2 species). The present study contributes to understanding zooplankton diversity and abundance in relation to physicochemical parameters of surface water across the islands of Ranganathittu Bird Sanctuary (RBS), highlighting the influence of environmental factors on community structure. | ||
