All coral taxa exhibited strong heterogeneity in their size-structure, with marked variation among depths, locations, and islands. Porites spp. and Acropora globiceps populations at 6 m depth were dominated by smaller size classes compared to other depths. Regional-scale variation was particularly evident for Pocillopora meandrina and A. globiceps, with a higher proportion of smaller colonies found at Raiatea, probably as a result of recent cyclones followed by higher recruitment rates. Porites spp. populations were characterized by a preponderance of larger colonies, and greater size ranges compared to the other two taxa. 036 UR250
