<description lang=en>While the fire coral Millepora platyphylla is an important component of Indo-Pacific reefs,where it thrives in a wide range of environments, the ecological and biological processesdriving its distribution and population structure are not well understood. Here, we quantifiedthis species' population structure in five habitats with contrasting hydrodynamic regimes inMoorea, French Polynesia; two in the fore reef: mid and upper slopes, and three in thelagoon: back, fringing and patch reefs. A total of 3651 colonies of fire corals were mappedand measured over 45,000 m2 of surveyed reef. Due to the species' sensitivity to fragmentationin response to strong water movement, hydrodynamic conditions (e.g. waves, pass andlagoonal circulation) corresponded to marked differences in colony size distributions, morphologyand recruitment dynamics among habitats. The size structure varied among reefhabitats with higher proportions of larger colonies in calm nearshore reefs (fringing andpatch reefs), while populations were dominated by smaller colonies in the exposed forereefs. The highest densities of fire corals were recorded in fore reef habitats (0.12±0.20 n.m-2) where the proportion of recruits and juveniles was higher at mid slope populations(49.3%) than on the upper slope near where waves break (29.0%). In the latter habitat, mostcolonies grew as vertical sheets on encrusting bases making them more vulnerable to colonyfragmentation, whereas fire corals were encrusting or massive in all other habitats. Thelowest densities of M. platyphylla occurred in lagoonal habitats (0.02±0.04 n.m-2) characterizedby a combination of low water movement and other physical and biological stressors.This study reports the first evidence of population structure of fire corals</description>
