Effects of elevated CO(2) on fish behaviour undiminished by transgenerational acclimation
Behaviour and sensory performance of marine fishes are impaired at CO(2) levels projected to occur in the ocean in the next 50–100 years, and there is limited potential for within-generation acclimation to elevated CO(2). However, whether fish behaviour can acclimate or adapt to elevated CO(2) over...
