Ocean Acidification Impedes Foraging Behavior in the Mud Snail Ilyanassa obsoleta
Ocean acidification may diminish the response of many marine organisms to chemical cues that can be used to sense nearby food and predators, potentially altering community dynamics. We used a Y-maze choice experiment to investigate the impact of ocean acidification on the ability of mud snails (Ilya...
