The Global Perspective of Incidence and Prevalence of Coral Diseases
Diseases occur globally in most coral reef habitats whether near human population centers or remotely offshore. They generally affect a low proportion of the susceptible species, although localized outbreaks have produced significant mortalities to scleractinian corals, gorgonians, sea urchins, reef fish, sponges, algae and other coral reef organisms (Peters, 1993; Harvell et al., 1999; Williams and Bunkley-Williams, 2000). There are now over 30 named diseases in the Caribbean basin affecting 45 zooxanthellate scleractinian corals, three hydrozoan corals, ten octocorals, two zoanthids, nine sponges and two crustose coralline algae (Green and Bruckner, 2000; Weil et al., 2006), and at least seven...

Photosynthetic Symbioses in Animals
Animals acquire photosynthetically-fixed carbon by forming symbioses with algae and cyanobacteria. These associations are widespread in the phyla Porifera (sponges) and Cnidaria (corals, sea anemones etc.) but otherwise uncommon or absent from animal phyla. It is suggested that one factor contributing to the distribution of animal symbioses is the morphologically-simple body plan of the Porifera and Cnidaria with a large surface area:volume relationship well suited to light capture by symbiotic algae in their tissues. Photosynthetic products are released from living symbiont cells to the animal host at substantial rates. Research with algal cells freshly isolated from the symbioses...

Coral Disease Handbook: Guidelines for Assessment, Monitoring & Management
Our research careers began in Discovery Bay, Jamaica, in the mid 1970s, where we both studied the behavior of coral reef organisms, rather than the corals themselves. At that time, living coral covered 70 percent of the bottom, and no one worried about the long term persistence of the reefs, even though the reefs were clearly impacted by people via severe overfishing. Quite simply, we took the reefs for granted. That sunny confidence turned out to be totally unfounded. In 1980, Hurricane Allen, a category five storm, struck and turned much of the reef into a rubble ground. However, reefs routinely get hit...

The shores of the small coral cay on Desroches Atoll (Amirante Islands, Seychelles) span a range of conditions from relatively sheltered (along the atoll lagoonal coast) to very exposed (facing the Indian Ocean). This appears in no way to affect the occurrence of Scaevola, which dominates the entire coastline, but the frequencies of the other characteristic but less widespread shoreline plant species (Casuarina, Cocos, Guettarda, Suriana and Heliotropium) show significant variation around the cay perimeter.
