Thus, active restoration propagates coral fragments in nurseries prior to outplanting to depleted reefs and is an effective coral restoration technique . x��Z[s�V~���ɎE�o�nw�I��6�Z�>�}�%��L�$o��/ �2i��d&�( �8\_VM~�n���חM�n�����ޔǿ֛o�l�[��i�������G?e�.�~��y���y�9? Acropora formosa, along with the Staghorn Coral Acropora cervicornis, has the densest base skeletons ever recorded in stony corals.They come in mostly cream, but also in brown, blue, pink, and green with pale tips. Acropora are the crown jewel of the SPS world. staghorn coral: [noun] any of several large branching corals (genus Acropora, especially A. cervicornis) that somewhat resemble antlers. Utila Coral Restoration is a conservation and research project which aims to restore the reefs around Utila, Honduras and to recover the critically endangered populations of both Acropora Cervicornis (Staghorn Coral) and Acropora Palmata (Elkhorn Coral) species. Scleractinia Bourne, 1900 – stony corals, madrépores : Suborder: Astrocoeniina Vaughan and Wells, 1943 Family: Acroporidae Verrill, 1902 Genus: Acropora Oken, 1815 Species: Acropora cervicornis (Lamarck, 1816) – staghorn coral Common species are the staghorn coral (Acropora cervicornis) and the elkhorn coral (A. palmata). They are a dominant coral and one of two species of Caribbean Acroporas. 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. Introduction. endobj have focused on staghorn coral (Acropora cervicornis) and elkhorn coral (A. palmata). 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. Florent's Guide To The Tropical Reefs - Staghorn Coral - Acropora cervicornis - Stony Corals - - Stony Corals - Caribbean, Bahamas, Florida - Staghorn Coral GALLERY Acropora cervicornis. 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. Having said that, Acropora are one of the most difficult corals to keep. Its branches are spaced more loosely with a more relaxed look to them. They are dominant, of the two species of Caribbean Acroporas. the region largely as a result of White Band Disease, a coral disease which remains poorly understood. II. The upper limit is defined by wave forces, and the lower limit is controlled by suspended sediments and light availability. It occurs in back reef and fore reef environments from 0 to 30 m (0 to 98 ft) depth. %���� Staghorn coral is, hands-down, the most ecologically valuable species in the Caribbean. [����0����L:�J'R�PƉL���ݧ��y��τ�@���ۧ�/�^{9����~�(���H?�-I_\�����Ce�n��㭔��8x��/p�A�~z¯���J������ These branches can increase length by 10-20cm each year, with sub branches developing at right angles (ADW, 2016). Staghorn coral can form dense groups called thickets in very shallow water. 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. Aronson et al. Staghorn coral, Acropora cervicornis, is a threatened species and the primary focus of western Atlantic reef restoration efforts to date. The staghorn coral Acropora cervicornis is the fastest growing Caribbean coral and is thought to reproduce largely by fragmentation . 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. 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 … Sedimentation of its aquatic habitat threatens the staghorn coral, as the increased sediment prevents light from reaching the lower portion of the coral … 3 0 obj They are dominant, of the two species of Caribbean Acroporas. The Staghorn Coral offers a variance on shape and structure in the Acropora genus. <> 2 0 obj This coral is now uncommon, though it is probably the most common of the two ’staghorn’ corals in many parts of the Caribbean region. They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. The Staghorn Coral has a slight variation in appearance in the Acropora genus. Geomorphology, zonation and sedimentary phases. and Staghorn (Acropora cervicornis) coral reef zones have almost disappeared from most islands in. (1998) describe a change in the southern lagoon reefs in which the dominant staghorn coral Acropora cervicornis has been replaced by Agaricia tenuifolia. It … : any of several large branching corals (genus Acropora, especially A. cervicornis) that somewhat resemble antlers. http://iucn.org/downloads/climatic_change_chapter_en_final.pdf. �U���N����cY�鼶=�����s�y=�����W`G��oݛ&}ؗU�\�Uz����8�� �EdK�Nv,��F��q�f�<5�7��V�gfሶ�e��2.��Uh�>��&G�y��V��8���qZ��c �uY���++�;f�l7��X}5�E��kL��0�9n�C2}�aR��D�TRZMh/�����D�J��Ul�_��������/3�����d�1��:��qa�{�om�X%��Z���G�. Elkhorn coral (Acropora palmata) * Mountainous star coral (Montastraea faveolata) Pillar coral (Dendrogyra cylindrus) Rough Cactus Coral (Mycetophyllia ferox) Staghorn coral (Acropora cervicornis) * Star coral (Montastraea franksi) * proposed to be reclassified from threatened to endangered Pacific. There are 160 different species of Staghorn Coral. Corals of the family Acroporidae are found in waters of the Atlantic and Pacific Oceans, where they are found in shallow reef systems. \���{O���“��?���P;��-彳A�[I�d:i���7�'�;=����dt76�,ۧ��O�B�Il�~�V���^�fU�7�8V#|ɯ���ٿ�Ϝ�r��o�D�\]p�� Significant population declines in Acropora cervicornis and A. palmata began in the 1970s and now exceed over 90%. It, along with elkhorn coral and star corals (boulder, lobed, and mountainous) built Caribbean coral reefs over the last 5,000 years. Goreau TF, Goreau NI (1973) The ecology of Jamaican coral reefs. Staghorn coral has been one of the three most important Caribbean corals in terms of its contribution to reef growth and fish habitat. Significant population declines in Acropora cervicornis and A. palmata began in the 1970s and now exceed over 90%. The most common color is cream to tan with colorful tips. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Get the educational wall poster with indepth information about about how climate change impacts animals. It grows anywhere between the water surface and a depth of about 100 feet. Since the 1980s, it has suffered drastic population losses with no signs of recovery and has been classified as a critically endangered species. 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.
