Description:

Population surveys of elkhorn coral, Acropora palmata, and its corallivorous snail predator, Coralliophila abbreviata, were conducted annually in May from 1998 to 2001. At each survey, size and condition of each sampled coral colony was estimated as well as the number and size of its resident snails. A. palmata patches at six sites in the FKNMS were surveyed in all years; three no-take zones and three reference areas. A drastic decline in A. palmata populations was observed between May 1998 and May 1999, coinciding with a severe bleaching event and Hurricane Georges during summer/fall of 1998. All colonies in three patches (out of 10) sampled in 1998 suffered complete mortality by May 1999. Sampling at two sites in October 1998, after Hurricane Georges, confirmed that average sizes of standing colonies and of loose fragments had decreased while the abundance of fragments had increased.
