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 poorly understood. We measured predation rates predator selectivity two closely related species damselfish exposed a predatory dottyback. found temperature CO2 interacted synergistically overall rate, but antagonistically selectivity. Notably, elevated or reversed selectivity, interaction between stressors cancelled Routine metabolic prey showed strong differences tolerance not temperature, these did correlate with recorded mortality. This highlights difficulty linking species-level physiological resulting outcomes. study is first document both synergistic antagonistic crucial process like predator-prey dynamics.

Much of the plasticity that prey exhibit in response to predators is linked prey's immediate background level risk. However, we know almost nothing how risk influences learn categorize and non-predators. Learning non-predators probably represents one most underappreciated aspects anti-predator decision-making. Here, provide larval damselfish ( Pomacentrus chrysurus ) with a high or low then try teach them recognize cue as non-threatening through process latent inhibition. Prey from low-risk were pre-exposed novel odour cues absence negative reinforcement for 3 days, provided opportunity threatening, failed subsequently respond threat. Fish high-risk showed much different response. These fish did not non-threatening, because cost falsely learning an higher when higher. Our work highlights appears drive cognition animals discriminate threats their environment.
