Article Synopsis
  • A comprehensive study on plankton dynamics was performed at various aquatic sites in Italy, focusing on both phytoplankton and zooplankton over time.
  • The research revealed key environmental factors such as nutrient levels, water stratification, and freshwater inflow, which significantly influence seasonal changes in plankton communities.
  • It also found that while long-term trends were uncommon, many sites faced multiple disturbances from human activity, climate variation, and nutrient inputs, showcasing the complex interactions affecting aquatic ecosystems.
