Abstract
Crude, aqueous extracts of five species of hermatypic coral from three scleractinian families were assayed for bioactivity against the early life stages of scleractinian corals. At concentrations between 62.5 and 250 μg/ml, extracts of all species were lethal to at least three of the five species of coral planulae larvae tested. To test for behavioral changes, extracts from four species were tested on planulae of the scleractinian Pocillopora damicornis. All four caused immediate but reversible behavioral aberrations in the larvae at concentrations as low as 7.8 μg/ml. To determine the effects on newly settled corals, postmetamorphosis juveniles (spat) of P. damicornis were exposed to extracts from four hermatypic species. They were either killed or suffered a reduction in growth rates. If released under natural conditions, substances with lethal or sublethal activities against the early life stages of other scleractinians could allow hermatypic corals to influence patterns of scleractinian recruitment, thus playing a role in ordering coral communities.
