Nutrient Loading Fosters Seagrass Productivity under Ocean Acidification
The effects of climate change are likely to be dependent on local settings. Nonetheless, the compounded effects of global and regional stressors remain poorly understood. Here, we used CO2vents to assess how the effects of ocean acidification on the seagrass, Posidonia oceanica, and the associated e...
