Effects of nutrient enrichment on macroalgal coralligenous assemblages

► Effects of nutrient enrichment on macroalgal coralligenous assemblages are evaluated. ► We simulate develop of nutrients pollution by a manipulative field experiment. ► Response of mature and early successional macroalgal assemblages were analyzed. ► Nutrient impact affects structure of both mature and early successional assemblages. ► Early successional assemblages were more sensitive to nutrient enrichment.
