Influence of exposure to elevated CO2 and habitat type on aggression.
Level of aggression displayed by juvenile Pomacentrus moluccensis (white) and P. amboinensis (grey) 45–60 min after release in size matched pairs onto a patch of habitat (healthy unbleached or bleached live Pocillopora damicornis). Fishes were either reared under ambient or elevated CO2 conditions. Aggression Index is calculated as Displays + (3× Bites) – Avoidances. Letters above the bars represent Tukey's HSD groups. Errors are standard errors. n = 26–29.
