Near-future carbon dioxide levels impair the olfactory system of a marine fish
Survival of marine fishes exposed to elevated near-future CO2 levels is threatened by their altered responses to sensory cues. Here we demonstrate a novel physiological and molecular mechanism based in the olfactory system which helps explain altered behavior under elevated CO2. We combine electroph...
