Spatial variation of hermatypic coral assemblages in Cayos Cochinos Archipelago, Honduras
Spatial variations of hermatypic coral assemblages were evaluated at five sites in Cayos Cochinos Archipelago, Honduras, in February 2008. Richness and coverage of corals and other benthic morpho-functional groups were estimated using 56 videotransects. Topographic complexity and depth were also mea...

Spatial variations of hermatypic coral assemblages were evaluated at five sites in Cayos Cochinos Archipelago, Honduras, in February 2008. Richness and coverage of corals and other benthic morpho-functional groups were estimated using 56 videotransects. Topographic complexity and depth were also measured by transect. Twenty-two coral taxa were recorded for Cayos Cochinos. Total species richness was similar (16 and 17 taxa) at all sites, whereas species richness by transect was different among sites (6-12 taxa). Shannon diversity showed weak differences among sites (1.46-2.13), whereas Pielou evenness was not different among sites. Simpson dominance was low with weak differences among sites (0.15-0.27). The total cover of hermatypic coral was 16.5% at Roatan Bank, 10.5% at Salamandinga, 9.7% at Punta Pelicanos, 7.6% at La Grupera, and 6.9% at Mariposales. The ANOSIM revealed assemblages of different corals between sites, except between La Grupera, Punta Pelicanos, and Salamandinga. The NMDS associated La Grupera, Punta Pelicanos, and Salamandinga given the greater contribution of Porites astreoides, Agaricia agaricites, and Montastraea annularis; whereas the NMDS differentiated Mariposales and Roatan Bank, which had more dissimilar assemblages with a greater predominance of Montastraea cavernosa, Agaricia agaricites, and Diploria labyrinthiformis.
