Risk-induced trait response in planktonic larvae is altered under an acidified scenario

Our changing climate is affecting predator-prey interactions in different ways. Increasing atmospheric CO2 is acidifying the ocean and disrupting the chemosensation of several species. Here, we evaluated a risk-induced trait response to a potential predator under an acidified scenario. Using plankto...
