  abstract = {{W}e studied a mesotrophic and a hypertrophic {M}editerranean coastal lagoon, both of which had been simultaneously subjected to a nutrient input reduction for 9 yr. {W}e compared these 2 lagoons to an oligotrophic coastal lagoon. {U}sing bioassays comprising 24 h incubations with added phosphorus and/or ammonium, we investigated the response of the phytoplankton communities to nutrient enrichment during summer in terms of biomass, size class structure, abundance and growth. {F}or nitrogen and phosphorus, we identified which nutrient limited phytoplankton growth, and what strategies of nutrient exploitation the communities adopted to cope with these limitations. {U}ltraphytoplankton dominated the 3 communities, but it differed in composition among the lagoons. {G}reen algae dominated in the hypertrophic lagoon, whereas the mesotrophic lagoon presented a higher diversity of phytoplankton groups. {P}icocyanobacteria and small diatoms were the most abundant groups in the oligotrophic lagoon, although they accounted for less biomass than green algae. {T}he communities of the mesotrophic and the hypertrophic lagoons strongly responded to the nutrient pulse, showing that the re-oligotrophication trajectories of these lagoons were still very vulnerable to occasional eutrophication events. {O}n the other hand, the oligotrophic lagoon marginally responded to the enrichment, indicating its adaptation to nutrient-depleted conditions. {W}e observed a shift along the eutrophication gradient, from a co-limitation by {N} and {P} in the oligotrophic and the mesotrophic lagoons to a single and strong {N} limitation in the hypertrophic lagoon. {E}ach community demonstrated specific use of internal, external or recycled nutrient pools under experimentally induced limitation.},
