Abstract:Acropora was present in Hawaii during the Miocene but disappeared
from the geological record during the Pleistocene. In the present
(Holocene), Acropora appears to be in the process of recolonizing the archipelago.
Three species have been found, all with centers of distribution in the
middle of the chain at French Frigate Shoals. The most likely source of the
Acropora recolonizing Hawaii is Johnston Island by way of the subtropical
countercurrent. Few other species of coral in Hawaii were extirpated during
the Pleistocene. Thus the history of Acropora in the archipelago may not be
representative of shallow-water marine forms in general. Nevertheless, the
record of Acropora in Hawaii supports the theory that distributional discontinuities
between many Pacific Island coral reef faunas are due to the net
product of local extinction and recolonization.
