Healthy populations of these corals provide a myriad of ecosystem services and benefits to local people, including protection from storms and wave surge, habitat for important fishery species, ecotourism (diving, snorkeling), and more. During the 1970’s and 1980’s populations of both A. cervicornis and A. palmata underwent precipitous declines in abundance (National Marine ​ ​ ​ Fisheries Service, 2015). This significant decline, documented to be as high as 97% across large sections of the Caribbean and Florida, greatly reduced these species’ ability to successfully reproduce through both of their natural reproductive strategies: sexual (broadcast spawning) and asexual (fragmentation). Based on current scientific understanding, the primary cause of this decline is attributed to disease, especially White Band Disease (WBD). However, synergistic effects from multiple threats (local, regional, and global) are impacting extant populations and impeding natural recovery. AZA member institutions have been directly engaged in field conservation and conservation-related education of these species and their habitat for many years. In March 2018, Columbus Zoo and Aquarium, Disney’s The Seas, The Florida Aquarium, Mote Marine Laboratory, Omaha’s Henry Doorly Zoo and Aquarium, John G. Shedd Aquarium, and Steinhart Aquarium proposed Atlantic Acropora corals as a SAFE program. This conservation action plan was approved in ​ ​ August 2019. Program Goal The long-term vision of the SAFE: Atlantic Acropora corals program is increased abundance ​ ​ and genetic diversity of wild populations of elkhorn coral (Acropora palmata) and staghorn coral ​ ​ (Acropora cervicornis), that these species remain extant throughout their native range, experience ​ ​ successful reproduction and recruitment, and provide valuable ecosystem services and benefits. The 3-year program goal supporting this vision includes a combination of conservation and restoration activities: (1) developing at least four capacity-building restoration centers in the region; (2) accelerating production and outplanting of both asexually and sexually-propagated corals; (3) increasing capacity of in situ and ex situ nurseries; (4) expanding partnerships with non-traditional ​ ​ ​ ​ collaborators to support restoration; (5) increase capacity for scientific research on topics supporting restoration through expanded partnerships and integration of AZA members into existing conservation networks; and (6) engaging our audiences on the threats facing these species and actions that they can take to reduce these threats. While the priority for the SAFE program will be on A. cervicornis and ​ ​ A. palmata, the project also includes research with their naturally-occurring F1 hybrid (A. prolifera). ​ ​ ​ We aim to increase the number of AZA-accredited member institutions directly participating in and contributing to the conservation of Atlantic Acropora corals (see Action Opportunities Summary ​ ​ List), and increase awareness of the global coral reef crisis and impacts to Atlantic Acropora species ​ ​ through our collective education, outreach and public engagement activities. Through these conservation and educational programs, AZA-accredited member institutions and project partners will 3 create a measurable positive impact on these populations and public awareness of their status, their importance, and their place in the global coral reef crisis. The following work plan was developed by a steering committee consisting of leaders from seven AZA member institutions (Columbus Zoo and Aquarium, Disney’s The Seas, Florida Aquarium, Mote Marine Laboratory, Omaha’s Henry Doorly Zoo and Aquarium, Shedd Aquarium, and Steinhart Aquarium), along with project partners, external advisors and the Aquatic Invertebrate Taxon Advisory Group. This plan supports the NOAA National Marine Fisheries Service Recovery Plan for Elkhorn ​ (Acropora palmata) and Staghorn (A. cervicornis) Corals, prepared by the Acropora Recovery Team ​ for the National Marine Fisheries Service in March 2015. The SAFE Atlantic Acropora Corals program invites and welcomes all interested AZA zoos ​ ​ and aquariums to become program partners, funders and collaborators. 4 Program Operational Structure Program Leadership: Bart Shepherd Senior Director, Steinhart Aquarium [email protected] California Academy of Sciences (415) 379-5445 Program Partners - Steering Committee: Mitch Carl Curator of Aquatics, [email protected] Omaha’s Henry Doorly Zoo and Aquarium (402) 738-6933 Erinn Muller Science Director, International Center for Coral [email protected] Reef Research and Restoration, (941) 388-4441 x310 Mote Marine Laboratory Keri O’Neil Coral Nursery Manager, [email protected] The Florida Aquarium (813) 425-1679 Mark Schick Director, Fishes Department, [email protected] Shedd Aquarium (312) 692-3189 M.

While these species are the priority, some of the program goals also ​ ​ include working with their naturally-occurring F1 hybrid (A. prolifera). ​ ​ Kingdom Animalia Phylum Cnidaria Class Anthozoa Order Scleractinia Family Acroporidae Genus species Acropora cervicornis ​ Acropora palmata Acropora prolifera Acropora cervicornis, “staghorn coral” Acropora palmata, “elkhorn coral” ​ ​ 6 Status of Taxa at AZA Member Institutions AZA Conservation Activities: Only a very few AZA member organizations manage populations of Atlantic Acropora corals ​ ​ within their facilities (Table 1). This is partly due to the difficulty of obtaining specimens, given the multiple levels of protection (state, federal, international), compounded by the difficulty of successfully managing aquarium populations in the long-term. Table 1: Number of AZA member organizations currently housing Atlantic Acropora corals. ​ ​ ​ Species Number of Organizations A. cervicornis 7 A. palmata 5 A. prolifera 0 Although the number of AZA member institutions managing Atlantic Acropora corals in their ​ ​ facilities is quite low, many members have been actively engaged in field conservation and research activities with these species, sometimes for more than a decade. Numerous AZA member institutions and their partners have been conducting restoration of Atlantic Acropora corals by outplanting corals ​ ​ to repopulate reefs in southern Florida and the greater Caribbean region. These generally occur via two modes: (1) asexual propagation, nursery management, and outplanting through partnership with the Coral Restoration Foundation in Florida, and (2) gamete collection, fertilization, settlement and outplanting of sexually-derived coral recruits at several locations in the Caribbean region in partnership with SECORE (SExual COral REproduction) International. The SECORE approach, where gametes are collected from wild corals and cross-fertilized in the lab, results in genetically-unique individuals that can be

Since the 1980s, population densities of Acroporidae have dramatically declined in the Caribbean Sea. Quantitative censuses of Acroporidae provide information on the number of colonies (i.e. ramets), but not on the number of genetically distinct individuals (i.e. genets). In this context, the aim of our study was to provide an overview of the genetic status of Acropora populations in Guadeloupe by examining the genotypic richness of Acropora palmata and Acropora cervicornis. Using 14 microsatellite loci, we found extremely low genotypic richness for both species from Caye-a`-Dupont reef (i.e. 0.125 for A. palmata and nearly zero for A. cervicornis). Because genetic diversity contributes to the ability of organisms to evolve and adapt to new environmental conditions, our results are alarming in the context of ongoing global warming as long periods of clonal growth without sexual recruitment may lead to the extinction of these populations.

  • Community Structure of Pleistocene Coral Reefs of Curacë Ao, Netherlands Antilles
    Ecological Monographs, 71(1), 2001, pp. 49±67 q 2001 by the Ecological Society of America COMMUNITY STRUCTURE OF PLEISTOCENE CORAL REEFS OF CURACË AO, NETHERLANDS ANTILLES JOHN M. PANDOLFI1 AND JEREMY B. C. JACKSON2 Center for Tropical Paleoecology and Archeology, Smithsonian Tropical Research Institute, Apartado 2072, Balboa, Republic of Panama Abstract. The Quaternary fossil record of living coral reefs is fundamental for un- derstanding modern ecological patterns. Living reefs generally accumulate in place, so fossil reefs record a history of their former biological inhabitants and physical environments. Reef corals record their ecological history especially well because they form large, resistant skeletons, which can be identi®ed to species. Thus, presence±absence and relative abun- dance data can be obtained with a high degree of con®dence. Moreover, potential effects of humans on reef ecology were absent or insigni®cant on most reefs until the last few hundred years, so that it is possible to analyze ``natural'' distribution patterns before intense human disturbance began. We characterized Pleistocene reef coral assemblages from CuracËao, Netherlands Antil- les, Caribbean Sea, focusing on predictability in species abundance patterns from different reef environments over broad spatial scales. Our data set is composed of .2 km of surveyed Quaternary reef. Taxonomic composition showed consistent differences between environ- ments and along secondary environmental gradients within environments. Within environ- ments, taxonomic composition of communities was markedly similar, indicating nonrandom species associations and communities composed of species occurring in characteristic abun- dances. This community similarity was maintained with little change over a 40-km distance. The nonrandom patterns in species abundances were similar to those found in the Caribbean before the effects of extensive anthropogenic degradation of reefs in the late 1970s and early 1980s.

  • Coral Health and Disease in the Pacific: Vision for Action
    IV. STATE OF KNOWLEDGE IN THE PACIFIC—WHAT DO WE KNOW AND WHAT HAVE WE LEARNED? OVERVIEW OF ISSUES UNIQUE TO THE PACIFIC: BIOLOGICAL & SOCIAL PERSPECTIVES Michael J. Gawel Guam EPA 120 Bengbing St. Y-Papao Dededo, GU 96929 [email protected] Pacific Islands The term “Pacific Islands” in the context of this paper arbitrarily refers to those tropical islands of the central and western Pacific Ocean which support shallow hermatypic coral reefs, but excluding the Hawaiian Archipelago, which is covered in other papers. The tropical Pacific Island nations and territories all support coral reefs and, no doubt, harbor coral diseases, although these have not been scientifically documented in many of the islands. In fact, as part of the U.S. National Action Plan to Conserve Coral Reefs, surveys in 2002 and 2004 of coral reef academic scientists, resource managers, government agencies and NGOs recorded that in the U.S. Pacific islands they perceived “no threat” from coral disease, although American Samoa registered an increase to perception of “moderate threat” in the 2004 survey (Waddell, 2005). This lack of concern partially reflects a lack of information on the status of diseases in many islands. Wilkinson (2004, p. 405) notes that in American Samoa and Micronesia “Coral bleaching and disease were either rare or undocumented in 1994, but are now clearly evident and considered a serious threat to many reefs in the region.” The Pacific island coral reefs range from veneers on newly emergent volcanic islands, to platform-like fringing reefs, to barrier reefs with lagoons, to atolls, and include non- emergent isolated banks.

  • Composition and Ecology of Deep-Water Coral Associations D
    HELGOLK---~DER MEERESUNTERSUCHUNGEN Helgoltinder Meeresunters. 36, 183-204 (1983) Composition and ecology of deep-water coral associations D. H. H. Kfihlmann Museum ffir Naturkunde, Humboldt-Universit~t Berlin; Invalidenstr. 43, DDR- 1040 Berlin, German Democratic Republic ABSTRACT: Between 1966 and 1978 SCUBA investigations were carried out in French Polynesia, the Red Sea, and the Caribbean, at depths down to 70 m. Although there are fewer coral species in the Caribbean, the abundance of Scleractinia in deep-water associations below 20 m almost equals that in the Indian and Pacific Oceans. The assemblages of corals living there are described and defined as deep-water coral associations. They are characterized by large, flattened growth forms. Only 6 to 7 % of the species occur exclusively below 20 m. More than 90 % of the corals recorded in deep waters also live in shallow regions. Depth-related illumination is not responsible for depth differentiations of coral associations, but very likely, a complex of mechanical factors, such as hydrodynamic conditions, substrate conditions, sedimentation etc. However, light intensity deter- mines the general distribution of hermatypic Scleractinia in their bathymetric range as well as the platelike shape of coral colonies characteristic for deep water associations. Depending on mechani- cal factors, Leptoseris, Montipora, Porites and Pachyseris dominate as characteristic genera in the Central Pacific Ocean, Podabacia, Leptoseris, Pachyseris and Coscinarea in the Red Sea, Agaricia and Leptoseris in the tropical western Atlantic Ocean. INTRODUCTION Considerable attention has been paid to shallow-water coral associations since the first half of this century (Duerden, 1902; Mayer, 1918; Umbgrove, 1939). Detailed investigations at depths down to 20 m became possible only through the use of autono- mous diving apparatus.

  • Elkhorn Coral: Science of Recovery
    Elkhorn Coral: Science of Recovery Florida Keys National Marine Sanctuary Once Abundant Coral Listed as Threatened Species Elkhorn coral, Acropora palmata, was once the most abundant stony coral on shallow reef crests and fore-reefs of the Caribbean and Florida reef tract. In the Florida Keys, this fast-growing coral with its thick antler-like branches formed extensive habitat for fish and marine invertebrates. By the early 1990s, elkhorn coral had experienced widespread losses throughout its range. A similar trend was seen in a close relative, staghorn coral, Acropora cervicornis. Multiple factors are thought to have contributed to coral declines, including impacts from hurricanes, coral disease, mass coral bleaching, climate change, coastal pollution, overfishing, and damage from boaters and divers. In 2006, the two species were listed as threatened under the Endangered Species Act. The recovery strategy, developed by NOAA Fisheries, included designating critical habitats in Florida, Puerto Rico Coral-eating snails covered in algae feed on elkhorn coral tissue.
