Influence of exposure to elevated CO2 and habitat type on shelter use.
The mean maximum distance that fishes ventured from the shelter of unbleached or bleached hard coral within 3 min behavioural observations for Pomacentrus moluccensis (white) and P. amboinensis (grey) that had been reared under ambient or elevated CO2 conditions. Letters above the bars represent Tukey's HSD groups. Error bars are standard errors (n = 26–29).
