Effects of ocean acidification on metabolic performance in coral reef fishes
Given the dramatic changes in atmospheric conditions over the 400MY evolutionary history of the fishes, physiological tolerance to elevated CO2 may not be unexpected. However, the most speciose genera of coral reef fishes radiated relatively recently (23MYA) – during a period of low CO2. And, althou...
