A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate . [ 1 ] Most coral reefs are built from stony corals , whose polyps cluster in groups.
The ecosystem services provided by intact reefs, seagrasses, and mangroves are both highly valuable and mutually enhance each other. Coastal protection (storm/wave attenuation) maintains the structure of adjacent ecosystems, and associated ecosystem services, in an offshore-to-onshore direction.
Reefs can also grow on other surfaces, which has made it possible to create artificial reefs. Coral reefs also support a huge community of life, including the corals themselves, their symbiotic zooxanthellae, tropical fish and many other organisms. Much attention in marine biology is focused on coral reefs and the El Niño weather phenomenon ...
The group is working to restore 5 acres of coral reef in Puerto Rico by planting fragments across six reefs and returning long-spined sea urchins to the ecosystem. ... It’s one of many ecosystem ...
Ecosystem services delivered by epibenthic bivalve reefs. Reefs provide coastal protection through erosion control and shoreline stabilization, and modify the physical landscape by ecosystem engineering, thereby providing habitat for species by facilitative interactions with other habitats such as tidal flat benthic communities, seagrasses and ...

Ocean acidification is a global threat to coral reef ecosystems. [26] Based on the biodiversity in the Coral Triangle area, damage will come to many sectors, because the coral reef is a fundamental ecosystem in the coastal area. Started by rising levels of atmospheric carbon dioxide, the calcium carbonate decrease then enhances bioerosion and ...
