Ocean Acidification Amplifies Multi-Stressor Impacts on Global Marine Invertebrate Fisheries

Elevated atmospheric carbon dioxide (CO 2 ) is causing global ocean changes and drives in organism physiology, life-history traits, population dynamics of natural marine resources. However, our knowledge the mechanisms consequences acidification (OA) – combination with other climatic drivers (i.e., warming, deoxygenation) on organisms downstream effects fisheries limited. Here, we explored how direct multiple conditions aerobic performance scales up to spatial impacts catch 210 commercially exploited invertebrates, known be susceptible OA. Under highest CO trajectory, show that potential declines by as much 12% year 2100 relative present, which 3.4% was attributed Moreover, OA are exacerbated regions greater pH (e.g., West Arctic basin), but reduced tropical areas where warming deoxygenation more pronounced Indo-Pacific). Our results enhance multi-stressor resources they can scaled from physiology dynamics. Furthermore, it underscores variability responses identifies vulnerable species.
