Abstract
Populations of the staghorn coral, Acropora cervicornis , collapsed throughout the Caribbean region from the late 1970s through the 1990s. We tested the hypothesis that this recent, multidecadal interruption in coral growth was a novel event in the late Holocene. Eight cores, extracted from a lagoonal reef in Discovery Bay, Jamaica dated to 440–1260 CalBP and consisted almost entirely of A. cervicornis rubble. The A. cervicornis in the cores showed significantly less internal bioerosion than A. cervicornis from modern death assemblages in Discovery Bay, indicating generally shorter post‐mortem exposure at the sediment–water interface in the past. A. cervicornis grew continuously and was buried rapidly during the millennium preceding the 1980s, with the exception of a possible hiatus in growth and burial at some point 300–600 years ago. In the 1980s, a combination of perturbations, which included overfishing and (possibly) other forms of human interference, caused an unprecedented disruption in the growth and burial of staghorn coral populations in Discovery Bay.
