We aimed to assess the impact of damming on the abundance, diversity and dissimilarity of microcrustaceans (Cladocera and Copepoda) along a large tropical river, in the context of the Serial Discontinuity Concept (SDC) and the River Continuum Concept (RCC). Over a two-year period, samples were collected bimonthly at six sites along a 750 km longitudinal gradient, and ten limnological variables were measured to understand their influence on the organisms. The results revealed spatial and temporal variations in limnological variables, as well as differences in microcrustacean abundance between upstream and downstream sites, with an increase observed downstream as in RCC. Some abundant species were oppositely separated according to spatial and seasonal gradients, and the influence of pluviosity, ammonia, temperature, pH, and alkalinity. The presence of a single large reservoir was found to influence the diversity and abundance of microcrustaceans downstream, supporting the SDC's predictions. The findings contribute to a better understanding of the impact of damming on river ecosystems and the downstream transport of organisms, as well as valuable insights for the ecological restoration of dammed rivers.
