Acidification and warming affect both a calcifying predator and prey, but not their interaction

Muscle length and claw strength of green crabs decreased after the crabs had been in ocean acidification conditions (pH 7.7) for 5 months. Periwinkles tended to have weaker shells in response to acidification. Predation by green crabs on periwinkles did not appear to change under ocean acidification conditions. (Laboratory study)
