These provide important habitat for other reef animals, especially fish. In the last 30 years the Staghorn Coral population has decreased by 80% from disease, pollution, development and damage. Goreau TF, Goreau NI (1973) The ecology of Jamaican coral reefs. Corals of the family Acroporidae are found in waters of the Atlantic and Pacific Oceans, where they are found in shallow reef systems. Its rapid growth rate makes it an excellent candidate for coral restoration programs. The staghorn coral (Acropora cervicornis) is a branching, stony coral with cylindrical branches ranging from a few centimetres to over two metres in length and height. Definition of staghorn coral. Its branches are spaced more loosely with a more relaxed look to them. Some of the species that live in the corals have already yeilded compounds … Staghorn coral also face the threat of disease like the white plague disease, a bacterial (Aurantimonas coralicida) disease that destroys tissue. Small patches can be found in shallow reef environments and occasionally in open areas of sand bottom. and Staghorn (Acropora cervicornis) coral reef zones have almost disappeared from most islands in. II. Elkhorn coral is named for its resemblance to elk antlers. General Diagnostics: Lesions on elkhorn coral (Acropora palmate) and staghorn coral (A. cervicornis) characterized by recent tissue loss separating live tissue and algal-colonized skeleton; no evidence of color change; absence of a pigmented band, no skeletal damage or abnormal growth.Lesions may be focal, multifocal, coalescing, linear or annular.

If you are looking for artificial coral or fake coral look no further. The staghorn coral Acropora cervicornis is the fastest growing Caribbean coral and is thought to reproduce largely by fragmentation . Currently, we are working with the species Acropora cervicornis, or staghorn coral. Thus, active restoration propagates coral fragments in nurseries prior to outplanting to depleted reefs and is an effective coral restoration technique . Reproduction in the wild by fragment regeneration and sexual recruitment is inadequate to offset population declines. Surprisingly some Acropora species have actually been seen capturing live fish (Sisson 1973). This coral is now uncommon, though it is probably the most common of the two ’staghorn’ corals in many parts of the Caribbean region. Acropora are the crown jewel of the SPS world. A coral is made up of thousands of tiny animals called polyps, protected by a hard skeleton.

They are dominant, of the two species of Caribbean Acroporas. Climate change is increasing the risk of extinction. Staghorn coral, Acropora cervicornis, is a threatened species and the primary focus of western Atlantic reef restoration efforts to date. It, along with elkhorn coral and star corals (boulder, lobed, and mountainous) built Caribbean coral reefs over the last 5,000 years. Elkhorn and staghorn corals were once the most abundant and important species on Atlantic/Caribbean coral reefs in terms of building reef structure. Coral reefs in the Florida Keys have degraded in recent decades, prompting efforts to re-establish populations of staghorn coral, Acropora cervicornis, to restore structure and ecological function. It’s commonly called staghorn coral because the pointed branches rise from the reef like antlers. Branches are up to 2m in length and 4-7cm in diameter. Named for its resemblance to elk antlers, elkhorn coral (Acropora palmata) is structurally complex with many large, thick branches.As with staghorn coral (Acropora cervicornis), the dominant reproduction mode of elkhorn coral is asexual fragmentation.New colonies form when branches break off of a colony and … The losses were caused by a combination of coral disease and bleaching, with possible contributions from other stressors, including pollution and predation. %���� Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. Here we use RNA-seq to evaluate how diel changes in gene expression vary within the branching Caribbean staghorn coral, Acropora cervicornis, between branch tips and branch bases. Acropora cervicornisis the fastest growing branching coral on reefs, with cylindrical branches in groups of three resembling stag (male deer) antlers (Fig. Significant population declines in Acropora cervicornis and A. palmata began in the 1970s and now exceed over 90%. (1998) describe a change in the southern lagoon reefs in which the dominant staghorn coral Acropora cervicornis has been replaced by Agaricia tenuifolia. If you are looking for artificial coral or fake coral look no further. Corals, specifically the Atlantic staghorn coral, Acropora cervicornis, are under major threat as disturbance events such as storms and disease and predation outbreaks increase in frequency. Coral gardening plays an important role in the recovery of depleted populations of threatened Acropora cervicornis in the Caribbean. Staghorn coral has been one of the three most important Caribbean corals in terms of its contribution to reef growth and fish habitat.
