Figure 1. Vertical distribution of damselfish juveniles.

The relative height above sand of three size groups of Pomacentrus amboinensis (white) and P. moluccensis (grey) juveniles on the reef edge, together with their height when they are not with the second species. Size or post-settlement age classes were: recent recruits (within the last week, ∼10–15.0 mm SL); juveniles from the previous lunar pulse (15–25 mm SL); juveniles that settled more than one month previously (>25 mm SL). Error bars are standard errors. Letters above bars represent Tukey’s HSD groupings. n = 30, except for the last two bars where n = 26 and 24.
