Interactive effects of ocean acidification and rising sea temperatures alter predation rate and predator selectivity in reef fish communities
Abstract Ocean warming and acidification are serious threats to marine life. While each stressor alone has been studied in detail, their combined effects on the outcome of ecological interactions are poorly understood. We measured predation rates and predator selectivity of two closely related speci...
