The role of the brain in the adaptation to climate change
The increase of CO2 in the oceans, termed ocean acidification, is projected to have detrimental effects on marine organisms. The magnitude of the impact on the marine ecosystems will depend on species capacity to adapt. Recent studies show that the behaviour of reef fishes is impaired at projected C...
