  • (Symbiodinium) in Scleractinian Corals from Tropical Reefs in Southern Hainan
    Journal of Systematics and Evolution 49 (6): 598–605 (2011) doi: 10.1111/j.1759-6831.2011.00161.x Research Article Low genetic diversity of symbiotic dinoflagellates (Symbiodinium) in scleractinian corals from tropical reefs in southern Hainan Island, China 1,2Guo-Wei ZHOU 1,2Hui HUANG∗ 1(Key Laboratory of Marine Bio-resources Sustainable Utilization, South China Sea Institute of Oceanology, Chinese Academy of Sciences, Guangzhou 510301, China) 2(Tropical Marine Biological Research Station in Hainan, Chinese Academy of Sciences, Sanya 572000, China) Abstract Endosymbiotic dinoflagellates in the genus Symbiodinium are among the most abundant and important group of photosynthetic protists found in coral reef ecosystems. In order to further characterize this diversity and compare with other regions of the Pacific, samples from 44 species of scleractinian corals representing 20 genera and 9 families, were collected from tropical reefs in southern Hainan Island, China. Denaturing gradient gel electrophoresis fingerprinting of the ribosomal internal transcribed spacer 2 identified 11 genetically distinct Symbiodinium types that have been reported previously. The majority of reef-building coral species (88.6%) harbored only one subcladal type of symbiont, dominated by host-generalist C1 and C3, and was influenced little by the host’s apparent mode of symbiont acquisition. Some species harbored more than one clade of Symbiodinium (clades C, D) concurrently. Although geographically isolated from the rest of the Pacific, the symbiont diversity in southern Hainan Island was relatively low and similar to both the Great Barrier Reef and Hawaii symbiont assemblages (dominated by clade C Symbiodinium). These results indicate that a specialist symbiont is not a prerequisite for existence in remote and isolated areas, but additional work in other geographic regions is necessary to test this idea.

  • SEDIMENTARY FRAMEWORK of Lmainland FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA
    GREAT BARRIER REEF MARINE PARK AUTHORITY TECHNICAL MEMORANDUM GBRMPA-TM-14 SEDIMENTARY FRAMEWORK OF lMAINLAND FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA D.P. JOHNSON and RM.CARTER Department of Geology James Cook University of North Queensland Townsville, Q 4811, Australia DATE November, 1987 SUMMARY Mainland fringing reefs with a diverse coral fauna have developed in the Cape Tribulation area primarily upon coastal sedi- ment bodies such as beach shoals and creek mouth bars. Growth on steep rocky headlands is minor. The reefs have exten- sive sandy beaches to landward, and an irregular outer margin. Typically there is a raised platform of dead nef along the outer edge of the reef, and dead coral columns lie buried under the reef flat. Live coral growth is restricted to the outer reef slope. Seaward of the reefs is a narrow wedge of muddy, terrigenous sediment, which thins offshore. Beach, reef and inner shelf sediments all contain 50% terrigenous material, indicating the reefs have always grown under conditions of heavy terrigenous influx. The relatively shallow lower limit of coral growth (ca 6m below ADD) is typical of reef growth in turbid waters, where decreased light levels inhibit coral growth. Radiocarbon dating of material from surveyed sites confirms the age of the fossil coral columns as 33304110 ybp, indicating that they grew during the late postglacial sea-level high (ca 5500-6500 ybp). The former thriving reef-flat was killed by a post-5500 ybp sea-level fall of ca 1 m. Although this study has not assessed the community structure of the fringing reefs, nor whether changes are presently occur- ring, it is clear the corals present today on the fore-reef slope have always lived under heavy terrigenous influence, and that the fossil reef-flat can be explained as due to the mid-Holocene fall in sea-level.

  • The Reproduction of the Red Sea Coral Stylophora Pistillata
    MARINE ECOLOGY PROGRESS SERIES Vol. 1, 133-144, 1979 - Published September 30 Mar. Ecol. Prog. Ser. The Reproduction of the Red Sea Coral Stylophora pistillata. I. Gonads and Planulae B. Rinkevich and Y.Loya Department of Zoology. The George S. Wise Center for Life Sciences, Tel Aviv University. Tel Aviv. Israel ABSTRACT: The reproduction of Stylophora pistillata, one of the most abundant coral species in the Gulf of Eilat, Red Sea, was studied over more than two years. Gonads were regularly examined using histological sections and the planula-larvae were collected in situ with plankton nets. S. pistillata is an hermaphroditic species. Ovaries and testes are situated in the same polyp, scattered between and beneath the septa and attached to them by stalks. Egg development starts in July preceding the spermaria, which start to develop only in October. A description is given on the male and female gonads, their structure and developmental processes. During oogenesis most of the oocytes are absorbed and usually only one oocyte remains in each gonad. S. pistillata broods its eggs to the planula stage. Planulae are shed after sunset and during the night. After spawning, the planula swims actively and changes its shape frequently. A mature planula larva of S. pistillata has 6 pairs of complete mesenteries (Halcampoides stage). However, a wide variability in developmental stages exists in newly shed planulae. The oral pole of the planula shows green fluorescence. Unique organs ('filaments' and 'nodules') are found on the surface of the planula;

ABSTRACT Background. The corallum is crucial in building coral reefs and in diagnosing systematic relationships in the order Scleractinia. However, molecular phylogenetic analyses revealed a paraphyly in a majority of traditional families and genera among Scleractinia showing that other biological attributes of the coral, such as polyp morphology and reproductive traits, are underutilized. Among scleractinian genera, the Euphyllia, with nine nominal species in the Indo-Pacific region, is one of the groups Submitted 30 May 2017 that await phylogenetic resolution.

  • Pleistocene Reefs of the Egyptian Red Sea: Environmental Change and Community Persistence
    Pleistocene reefs of the Egyptian Red Sea: environmental change and community persistence Lorraine R. Casazza School of Science and Engineering, Al Akhawayn University, Ifrane, Morocco ABSTRACT The fossil record of Red Sea fringing reefs provides an opportunity to study the history of coral-reef survival and recovery in the context of extreme environmental change. The Middle Pleistocene, the Late Pleistocene, and modern reefs represent three periods of reef growth separated by glacial low stands during which conditions became difficult for symbiotic reef fauna. Coral diversity and paleoenvironments of eight Middle and Late Pleistocene fossil terraces are described and characterized here. Pleistocene reef zones closely resemble reef zones of the modern Red Sea. All but one species identified from Middle and Late Pleistocene outcrops are also found on modern Red Sea reefs despite the possible extinction of most coral over two-thirds of the Red Sea basin during glacial low stands. Refugia in the Gulf of Aqaba and southern Red Sea may have allowed for the persistence of coral communities across glaciation events. Stability of coral communities across these extreme climate events indicates that even small populations of survivors can repopulate large areas given appropriate water conditions and time.

UNEP-WCMC aims to help decision-makers recognise the value of biodiversity to people everywhere, and to apply this knowledge to all that they do. The Centre’s challenge is to transform complex data into policy-relevant information, to build tools and systems for analysis and integration, and to support the needs of nations and the international community as they engage in joint programmes of action. UNEP-WCMC provides objective, scientifically rigorous products and services that include ecosystem assessments, support for implementation of environmental agreements, regional and global biodiversity information, research on threats and impacts, and development of future scenarios for the living world.
