Macroalgal communities face the challenge of changing biotic interactions: Review with focus on the Baltic Sea

Studies to analyze and examine the effects of eutrophication on the modification of the biotic interactions in the littoral macroalgal communities in the Baltic Sea were conducted. The analysis reveals that the biotic interactions, instead of remaining fixed keep evolving, which also reveals that the potential of plants and grazers to adapt is very crucial for their survival in the changing environment.
