To explore the impacts of multiple environmental stressors on animal communities in aquatic ecosystems, we selected protozoa—a highly sensitive group organisms—to assess effect change. conduct this simulation conducted a three-factor, outdoor, mesocosm experiment from March to November 2021. Changes community structure and functional composition protozoan under separate combined effects these three were investigated by warming addition nitrogen, phosphorus, pesticides. The results as follows: (1) Both eutrophication pesticides had considerable promotional abundance biomass protozoa; was not considerable. When with pesticides, there synergistic antagonistic effect, respectively. (2) Eutrophication promoted α diversity protozoa affected their species richness dominant composition; combination remarkably reduced protozoa. (3) Warming, eutrophication, important factors affecting groups Interaction among different could complicate changes ecological environment its communities. Indeed, context climate change, it might be more difficult predict future trends community. Therefore, our provide scientific basis for protection restoration shallow lake ecosystems; they also offer valuable insights predicting lakes.
