Juvenile corals

Juvenile corals were ≤ 4-cm diameter, and were surveyed from 1994 to 2020 at six sites. Juveniles were unlikely to be sexually mature, and were identified assuming sexual maturity is reached at ~ 4 cm diameter. Favia fragum and Siderastrea radians probably achieved sexual maturity at < 4 cm and were excluded from the analyses.

Juvenile corals were counted in quadrats (0.5 × 0.5 m, n = 40) randomly placed along one 40-m transect at each site, with surveys conducted in May (1995-1995) or July/August (1994 and 1998-2020). Corals were identified to species or genus, and the results pooled among taxa.
