Elkhorn coral (Acropora palmata) is a prominent Caribbean reef-building coral, although as of the s populations were still recovering from white band disease outbreak. This species is structurally complex with many large branches. The coral structure resembles that of elk branches create habitats for many other reef species, such as lobsters, parrot-fish, snapper shrimps and Class: Anthozoa. However, other important coral reefs are present in the Caribbean. The Mesoamerican Barrier Reef, stretching from the tip of the Yucatan Peninsula in .
Coral reefs in Belize have declined in abundance over the past decade. The reefs have experienced massive losses due to many local and global stressors such as bleaching, disease, sewage, overfishing, climate change, and tourism damage. After Hurricane Iris in , the coral reef in Belize was left. A team of researchers working on a Carnegie expedition in Australia's Great Barrier Reef has documented that coral growth rates have plummeted 40% .

The growth rates of four species of corals, Acropora cervicornis (Lamarck), Porites porites (Pallas), Madracis asperula (Milne-Edwards and Haime) and Montastrea annularis (Ellis and Solander) were determined at Barbados and Jamaica.
These were compared with growth rates of the same species elsewhere in the Caribbean.

McGill Univ. Marine Science Manuscript. McGill Univ. Marine Science Manuscript. Rep. 10, p. 1– The growth potential of modern zooxanthellate corals from the major reef provinces is reviewed with respect to Holocene reef growth.
Both coral growth and reef growth is enhanced globally at the beginning of the Holocene and is maintained regionally in the Caribbean Sea up to the present in contrast to reefs of the Indo-Pacific Ocean.
This regional difference is mainly caused by the Cited by: Caribbean coral reefs are among the most degraded reefs on the planet 1, systematic reef monitoring began in the s, researchers have documented a dramatic ‘phase shift’ on Caribbean Cited by: Abstract.
The in-situ growth rate of the reef coral Montastrea annularis on a reef at Jamaica, W. Indies was determined for a 1-year period using Alizarin Red-S staining techniques. Growth rate is correlated with water depth and growth form.
The flattened growth form of M. annularis allows for continued rapid increase in colony surface area at low light by: Introduction. The worldwide decline of coral reefs over the past several decades has been particularly devastating in the Caribbean where reefs have sustained massive losses, especially of reef-builders such as Acropora cervicornis, A.
palmata, and Orbicella spp. (Gardner et al., ; Hoegh-Guldberg et al., ).These declines were driven and continue to be affected by disease and other Cited by: Conditions for Growth of Coral Reefs. The coral and the associated organisms and algae, which are the most common reef builders are confined to the tropical belt.
The entire island of Bonaire is surrounded by a marine park that protects some of the most vibrant coral reefs in the Caribbean. At points all along the island’s calm western shore, divers and snorkelers can wade in from shore to discover a wealth of underwater diversity.

m per years. Factors that affect growth rate. 1) overfishing of herbivorous fish. Calcification rates on coral reefs can reach up to 12 kg ( lbs) CaCO 3 /m 2 /year for high energy reef areas with almost total coral cover (Kinsey, ). Estimations for closed systems have ranged from to kg ( to lbs) of CaCO 3 /m 2 /year (Carlson, ).
In the late s, as little as 2% of corals were considered to be endangered. Byan article in Science wrote that over 30% of the world's + species of reef-building corals were threatened with extinction, making coral the most endangered species on the planet.
What could possibly be to blame for this overwhelming and rapid decline in coral reef health and stability.

Norris1 Caribbean coral reefs have transformed into algal-dominated habitats over recent decades. Coral growth and reef growth were decoupled, in that coral growth rates did not reliably predict rates of reef accretion. The apparently paradoxical combination of normal to rapid coral growth and net reef erosion on polluted reefs illustrates the need for a whole-reef perspective on coral reef health.
Ó Elsevier Science Ltd. All rights File Size: KB. Reefs in this sea are often covered with sponge, gorgonians, corals and sea squirts, all on the same tiny patch of reef. It’s replicating this, which truly makes a Caribbean biotope feel authentic. There are well over 30 corals recorded in the Caribbean Sea, two of which remain on NOAA’s threatened species list, and are illegal to import or.
Growth rates for both species fit the expectations of linear rates of growth, explaining between 86 and 88% of the variance; however, a second order polynomial curve explained between 94 and 97% of the variation indicating that growth rates likely accelerated towards the end of the experiment (Fig.
3).Cited by: Coral reefs take time to grow, and some have questioned whether certain coral reefs could have grown to their present size in the time since the Flood. Evidence reported here indicates that rates of coral reef growth are quite variable, depending on water temperature, carbonate concentration, and depth.
At the surface, ultraviolet light inhibits coral growth, so surficial measurements of coral. In some areas of Florida and the Caribbean, coral cover has declined by 50–80 per cent in just the last three decades.

However, many known factors can affect coral reef growth rates. Now, a year study of Caribbean coral reefs confirms the unpredictability of using such growth as a "clock.".Start studying Conditions for Reef Growth. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
