Global Reef Expedition Final Report: Navassa

Page 14

out of 1540 (0.3% prevalence) displayed active disease signs with similar proportions noted as pale or with recent predation scars. Though the size data has not been analyzed yet, there were notable shifts in species composition (Table 4). The proportional representation of larger reefbuilding species such as Diploria spp has declined slightly, while the proportion of Agaricia spp. has declined substantially. Meanwhile, the representation of S. siderea, M. meandrina and S. intercepta has increased notably due to strong recruitment evidenced by the observation of many small colonies. Table 4.
