Zooplankton diversity patterns, assemblage, and environmental determinants in a seasonally dynamic tropical river.

ABSTRACT: ObjectiveThis study examined the composition, diversity, and assemblage of zooplankton in relation to environmental factors in the coastal Dakatia River, Bangladesh, across wet and dry seasons.MethodsZooplankton samples were collected seasonally (monsoon and winter) from each station, alongside measurements of environmental parameters. Population density, diversity indices, assemblage patterns, and environmental drivers of the zooplankton community were analyzed.ResultsA total of 25 zooplankton genera were recorded, dominated by Rotifera (36%), followed by Copepoda (26.49%), Cladocera (21.25%), and crustacean nauplii (16.26%). Zooplankton density varied significantly (p < 0.05) between the seasons, with the highest mean (144.88 ± 22.94 ind./L) during the winter (dry) and the lowest
