摘要

Sponges are sessile organisms capable of colonizing diverse substrata. In the Caribbean, coral reefs have suffered a drastic decline, and branching corals of the genus Acropora have been widely decimated. On dead coral skeletons and around surviving tissue the settling of sessile organisms can be observed, sponges being common. In order to investigate whether or not sponges have a preference for a particular species of coral, or for specific microhabitats of the colonies, we evaluated species composition, cover, richness and diversity of sponges colonizing the dead parts of still live colonies of the branching corals Acropora palmata and Acropora cervicornis in five locations of the Tayrona National Natural Park in the Colombian Caribbean. Ten colonies of Ac.palmata were quantified in each of the five locations, and eight Ac.cervicornis colonies in each of two locations. Quantification was carried out using video taken within 0.625-m(2) photoquadrats. Seventeen sponge species were found, 13 of them associated with Ac.palmata and seven with Ac.cervicornis. Desmapsamma anchorata, Clathria venosa and Scopalina rutzleri were found to be common to all Ac.palmata locations, while De.anchorata occurred in the two Ac.cervicornis locations. On Ac.palmata, encrusting sponges dominated, while on Ac.cervicornis branched and lobed sponges predominated. Significant differences in sponge cover were not found among locations but were observed in the sponge species present. On Ac.palmata the species with highest cover were D.anchorata and Cla.venosa, while on Ac.cervicornis it was De.anchorata. The richness and diversity of sponges were low for both coral species, and their varying distribution can be attributed to the differences in available substrate for attachment, given coral colony morphology; for Ac.palmata, sponges predominated on the underside of the branches, semi-cryptic areas and colony bases, whereas for Ac.cervicornis, they were located over the entire area of the cylindrical branches. Surviving colonies of Ac.palmata and Ac.cervicornis that are still erect offer additional microhabitats for reef sponges, some of which can be found directly interacting with live coral tissue, further threatening their recovery.
