Florent's Guide To The Tropical Reefs - Staghorn Coral - Acropora cervicornis - Stony Corals - - Stony Corals - Caribbean, Bahamas, Florida - endobj Its rapid growth rate makes it an excellent candidate for coral restoration programs. Elkhorn and staghorn corals were once the most abundant and important species on Atlantic/Caribbean coral reefs in terms of building reef structure. Currently, we are working with the species Acropora cervicornis, or staghorn coral. This coral is now uncommon, though it is probably the most common of the two ’staghorn’ corals in many parts of the Caribbean region. The coral receives nutrients and oxygen from algae, and the algae receive nutrients and carbon dioxide from the coral. Paige Gill, FKNMS. Staghorn Coral GALLERY Acropora cervicornis. Small patches can be found in shallow reef environments and occasionally in open areas of sand bottom. Staghorn Coral Latin name: Acropora Cervicornis, Conservsation status: critically endangered (population is stable) Coral reefs are the most diverse ecosystems in the marine world and can take 10,000 years to form. The Staghorn Coral, Acropora Cervicornis is one of those 3. 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. Acropora cervicornis larvae – baby Staghorn coral – are swimming around in their petri dish, just 7 days after he and a world-renowned team of scientists collected 25 mL of concentrated eggs from the spawning Acerv at the Coral Restoration Foundation Nursery. Surprisingly some Acropora species have actually been seen capturing live fish (Sisson 1973). Staghorn coral also face the threat of disease like the white plague disease, a bacterial (Aurantimonas coralicida) disease that destroys tissue. Historically, Acropora cervicornis and Acropora palmata have dominated the region, building shallow reefs with branched structures that provide crucial … Rising sea temperature increases algae growth so oxygen levels become too high for the coral, causing "bleaching"—the coral expels the algae and dies. Staghorn corals, as with all members of the subclass Zoantharia, have tentacles in multiples of three. Significant population declines in Acropora cervicornis and A. palmata began in the 1970s and now exceed over 90%. <> 4 0 obj The Staghorn Coral offers a variance on shape and structure in the Acropora genus.

Since its population declines due to a wide spread disease event in the early 1980s, limited long-term monitoring studies describing the impact of current threats and potential recovery have been completed. Acropora cervicornis under light microscopy, exhibiting signs of rapid tissue loss. Fore reefzones at intermediate depths 5–25 m (16–82 ft) were formerly dominated by extensive single-species stands of staghorn coral until t… Elkhorn and staghorn corals were once the most abundant and important species on Atlantic/Caribbean coral reefs in terms of building reef structure. Elkhorn and Staghorn corals are currently listed as “Critically Endangered” on the International Union for. Reproduction in the wild by fragment regeneration and sexual recruitment is inadequate to offset population declines. In order to fill that gap, the present work conducted a field experiment consisting of two different types of coral nutrient enrichments (treatment 1, nitrogen only; treatment 2, nitrogen + phosphorus) using the staghorn coral Acropora cervicornis as model organism. the region largely as a result of White Band Disease, a coral disease which remains poorly understood. It’s commonly called staghorn coral because the pointed branches rise from the reef like antlers. They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. Staghorn corals also eat planktonic animals which float by in the water (McGregor 1974).

Elkhorn (Acropora palmata) and staghorn (A. cervicornis) corals were listed as threatened under the U.S. Unfortunately many of our colonies look to be struggling to survive, often with more dead branches than living ones. It occurs in back reef and fore reef environments from 0 to 30 m (0 to 98 ft) depth. Thus, active restoration propagates coral fragments in nurseries prior to outplanting to depleted reefs and is an effective coral restoration technique . http://iucn.org/downloads/climatic_change_chapter_en_final.pdf. With branches that are more loosely spaced, they have a more "laid back" look to them. A coral is made up of thousands of tiny animals called polyps, protected by a hard skeleton.

This information is desperately needed in the Caribbean where the 2 dominant shallow water corals Acropora cervicornis and Acropora palmata have suffered unprecedented declines. 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. <> Its branches are spaced more loosely with a more relaxed look to them. Coral gardening plays an important role in the recovery of depleted populations of threatened Acropora cervicornis in the Caribbean. stream Corals live in symbiotic (mutually beneficial) relation with algae. 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.

Comprised of 368 species, the genus Acropora is the world’s most abundant coral group. Over the past decade, high survival coupled with fast growth of in situ nursery corals have allowed practitioners to create healthy and genotypically diverse nursery stocks. Staghorn coral is, hands-down, the most ecologically valuable species in the Caribbean. 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. Elkhorn coral is named for its resemblance to elk antlers. No other Genus has the sheer number of species as Acropora and when reef aquarists talk about the requirements to keep an SPS system, they are talking specifically about the care requirements of Acropora. Staghorn Coral. Staghorn coral has been one of the three most important Caribbean corals in terms of its contribution to reef growth and fish habitat. Staghorn coral, Acropora cervicornis, is a threatened species and the primary focus of western Atlantic reef restoration efforts to date. Endangered Species Act (ESA) on May 9, 2006.

The upper limit is defined by wave forces, and the lower limit is controlled by suspended sediments and light availability. Background The drastic decline in the abundance of Caribbean acroporid corals (Acropora cervicornis, A. palmata) has prompted the listing of this genus as threatened as well as the development of a regional propagation and restoration program. Climate change is increasing the risk of extinction. Endangered Species Act (ESA) on May 9, 2006. We compared linear extension, calcification rate, and skeletal density of nursery-raised A. cervicornis branches reared for 6 months either on blocks attached to … Corals of the family Acroporidae are found in waters of the Atlantic and Pacific Oceans, where they are found in shallow reef systems. In 2006, these two important reef-building species were listed as threatened under the Endangered Species Act due to significant declines in their populations throughout the wider Caribbean, including the Florida Keys. There are 160 different species of Staghorn Coral. It is the fastest growing species of coral in western Atlantic waters, growing at a rate of four to eight inches (10.2-20.3 centimeters) every year (National Park Service, n.d.). Genetic research has demonstrated that gene flow is regionally restricted across the Caribbean in both species. Pointed branches of Acropora cervicornis rise from the reef like antlers and the common name for this corals is the Staghorn Coral.
