Developing a framework for assessing interactions between multiple anthropogenic stressors remains an important goal in environmental research. In coastal ecosystems, the relative effects of global climate change (e.g. CO2 concentrations) and localized stressors (e.g. eutrophication), in combination, have received limited attention. Our in situ experiment reveals that global stressors such as ocean acidification (OA) may take precedence over local eutrophication in altering the community structure of seagrass epiphytes. Given that nutrient-driven algal overgrowth is commonly cited as a widespread cause of seagrass decline, our findings highlight that alternate climate change forces, such as OA, may exert proximate control over epiphyte community structure.
