Figure 1. Effects of elevated CO₂ on predator attack performance.

Comparison of the effects of elevated CO₂ (440, 880 µatm) on interactions between a predator (Pseudochromis fuscus) and prey (Pomacentrus amboinensis) on 3 performance variables of the predator: (a) predator success (b) predation rate and (c) predator attack distance. (a) N = 21, 16, 16, 21, (b) N = 21, 16, 16, 21 and (c) N = 17, 15, 12, 16 (left to right). Errors are standard errors. Letters above bars represent Tukey’s HSD groupings of means.
