Short summary
We found that the multi-level meadow response to nutrient enrichment was faster and stronger than to CO2 enrichment, being both mediated by shifts in leaf epiphyte or sediment communities. Our findings highlight the relevance of integrative approaches considering not only species interactions and connections between organization levels, but also the effect of interactive stressors, to anticipate the evolution of seagrass meadows in the near future and to endorse conservation efforts.
