Resumen:
In aquatic ecosystems,global change encompasses human-induced variations in the upper layer of thewater column, where most of carbon fixation takes place. These changes includeincrements of exposure to solar UV radiation, mean temperature of surface seawater,ocean acidification and nutrient concentrations. These factors are well knownto affect plankton ecosystems, although not all organisms are equally affected.In addition, many times these factors interact and the final results are notalways additive or synergistic as expected. Finally, indirect effects (e.g.,through trophic interactions) are often more pronounced than direct ones (e.g.,survival or growth), which tend in some cases to mask overall and long-term expectedecological shifts in plankton communities. We review the main contributions inthis field from the Atlantic coast of South America and discuss in a finalsection what have we learned and what is still unknown as global changes seemsto be here to stay.
