A triple trophic boost: How carbon emissions indirectly change a marine food chain
The pervasive enrichment of CO2 in our oceans is a well-documented stressor to marine life. Yet, there is little understanding about how CO2 affects species indirectly in naturally complex communities. Using natural CO2 vents, we investigated the indirect effects of CO2 enrichment through a marine f...
