Rapid evolution fuels transcriptional plasticity to ocean acidification
Abstract Ocean acidification (OA) is postulated to affect the physiology, behavior, and life‐history of marine species, but potential for acclimation or adaptation to elevated p CO 2 in wild populations remains largely untested. We measured brain transcriptomes of six coral reef fish species at a na...
