Ocean acidification ameliorates harmful effects of warming in primary consumer
Climate change-induced warming and ocean acidification are considered two imminent threats to marine biodiversity and current ecosystem structures. Here, we have for the first time examined an animal's response to a complete life cycle of exposure to co-occurring warming (+3°C) and ocean acidif...

Climate change-induced warming and ocean acidification are considered two imminent threats to marine biodiversity and current ecosystem structures.
