Deep-Sea Corals Science and Management Third International Symposium on Deep-Sea Corals Science and Management PROGRAM AND ABSTRACT BOOK November 28-December 2, 2005 University of Miami Rosenstiel School of Marine and Atmospheric Science Miami, Florida, USA Project # 0507 November 28-December 2, 2005 z Miami, FL, USA November 28, 2005 Dear Symposium Participant, It is a great pleasure to welcome you all to the 3rd International Symposium on Deep-Sea Corals. The purpose of the symposium is to provide a forum for scientific information exchange and explore new concepts and future collaboration among the participants. What will be discussed over the course of the next few days promises to be an exciting insight into the significant advances in ocean science and management of coldwater corals, sponges, seamounts, and associated fauna. We hope that you will participate in the creative discussions that will expand our collective understanding of the complex array of topics under the eight themes developed by the symposium advisory committee. Increasing interest in understanding and protecting deep-water ecosystems is clearly evident in discussions taking place at the United Nations and in several countries around the world. Interest in presenting and discussing scientific advances and ways to protect these areas has grown as well. In 2000, the 1st International Symposium on Deep-Sea Corals took place in Halifax, Canada, with 42 oral presentations and 22 posters comprising the agenda. Three years later in Erlangen, Germany, the symposium had grown into 67 oral presentations and 42 posters. Realizing that the amount of interest and scientific advances in deepwater ecology was quickly expanding, the International Steering Committee decided to hold this symposium two years later, not three. This decision seems to have been warranted as we received approximately 200 abstracts from 29 countries, translating into 9 keynote addresses, 102 oral presentations, and 88 posters. We wish to thank the various sponsors and co-sponsors of this symposium as well as the host institution, the prestigious Rosenstiel School of Marine and Atmospheric Science of the University of Miami. The University of Florida/IFAS Office of Conferences and Institutes has worked hard to ensure that all of the symposium’s activities meet your expectations. On behalf of the members of the international steering committee, symposium core committee, advisory committee, local arrangement committee, and the 16 co-conveners who all contributed time, enthusiasm, and resources. Welcome to the international city of Miami, Florida, USA! Robert J. Brock Robert Y. George NOAA Fisheries Service George Institute for Biodiversity and Sustainability Co-Organizer Co-Organizer i Third International Symposium on Deep-Sea Corals ii November 28-December 2, 2005 z Miami, FL, USA 28 November 2005 TO: All participants of the Third International Symposium on Deep-Sea Corals Rosenstiel School of Marine and Atmospheric Sciences University of Miami Dear Deep-Water Coral Scientists: As an advocate of conservation of biodiversity on Earth, I am thrilled to learn from Prof. Bob George (co-organizer of the symposium) that 250 deep-coral researchers and science managers from 30 nations are assembling today in Miami, to synthesize existing knowledge on habitat- forming azooxanthellate cold corals. I realize that numerous described and undescribed invertebrate species and fish fauna area associated with these colorful and spectacular seamounts and undersea gardens in the world oceans. I wish you all a successful conference and confluence of ideas (consilience) that can pave the way for wise management of these ecosystems by national and international governments. When Bob invited me to address this assembly of scientists in Miami, I realized that I have a field trip scheduled in the same time in the Dominican Republic, not too far from Miami. This conflict of schedule did not allow me to be with you all today. However, my thoughts are with you for achieving the goal of preventing biodiversity decline. The ecosystem collapse can be caused by habitat destruction due to bottom commercial trawling (physical destruction). It can also happen by silent extinction of even undescribed deep-sea species (such as unknown) species of sharks in the abyss, due to changes in thermohaline distribution (as induced by climate change-man’s activities included) or disruption of ecosystem structure and function (long-line fishing of predatory species in the top of food pyramids in seamounts). The “Storm over Amazon” and “Unmined Riches,” which I describe in my book on ‘Biodiversity’ (1992), are equally true for land and marine ecosystems. Time has come for scientists in all nations to take every action possible to conserve and protect biodiversity. I wish all a pleasant time in Miami and a productive outcome of this international conference. Sincerely Edward O.

  • Pearls and Organic Gemstones
    Pearls and Organic Gemstones INTRODUCTION Pearls were probably the first discovered gems of significance. Because they need no cutting or treatment to enhance their beauty and are rare natural occurrences, they have most likely always been highly esteemed. Organic gemstones are anything created by living processes. We have looked at amber in the past, but bone, teeth (such as ivory), and shells all have some value and are used today as gemstones. Pearls in General A pearl is grown by a mollusk (a bivalve such as a clam, oyster, or mussel or snail [single shell = valve]) in response to an irritant. Bivalves (two shelled mollusks) that secrete pearls live in both fresh‐ and saltwater. The irritant in most cases is a parasite (though it could be a grain of sand or other object). The parasite, a worm or other creature, is walled off by a secretion of calcium carbonate and protein. The calcium carbonate is the same as the inorganic material that makes stalactites in caves, and the protein is called conchiolin. The combination of these two substances (calcium carbonate and protein) makes the pearl's nacre (Nacre is also called mother of pearl). The nacre is a lustrous deposit around the irritant and forms concentric layers (overlapping circles). Many concentric layers of nacre build up over a period of a few years creating a pearl. The internal pattern is much like that seen in a jawbreaker. The layers create a sheen or luster that has iridescence and is described as both pearly luster and if colors of the rainbow are present, the pearl's orient.

Here we provide the first comprehensive phylogenetic analysis of the Chrysogorgiidae, and compare phylogeny and depth distribution. Phylogenetic relationships among 10 of 14 currently-described Chrysogorgiidae genera were inferred based on mitochondrial (mtMutS, cox1) and nuclear (18S) markers. Bathymetric distribution was estimated from multiple sources, including museum records, a literature review, and our own sampling records (985 stations, 2345 specimens). Genetic analyses suggest that the Chrysogorgiidae as currently described is a polyphyletic family. Shallow-water genera, and two of eight deep-water genera, appear more closely related to other octocoral families than to the remainder of the monophyletic, deep-water chrysogorgiid genera. Monophyletic chrysogorgiids are composed of strictly (Iridogorgia Verrill, 1883, Metallogorgia Versluys, 1902, Radicipes Stearns, 1883, Pseudochrysogorgia Pante & France, 2010) and predominantly (Chrysogorgia Duchassaing & Michelotti, 1864) deep-sea genera that diversified in situ.

  • New Observations on Rhabdopleura Kozlowskii (Pterobranchia) from the Bathonian of Poland
    ACT A PAL A EON T 0 LOG IC A POLONICA Vol. XVI 1971 No. ( CYPRIAN KULICKI NEW OBSERVATIONS ON RHABDOPLEURA KOZLOWSKII (PTEROBRANCHIA) FROM THE BATHONIAN OF POLAND Abstract. - Specimens of Rh. kozlowskii Kulicki, 1969 have here been described from the Bathonian of southern Poland. A secondary layer, never observed before, has been found inside zooidal tubes. INTRODUCTION At present, the genus Rhabdopleura is represented by at least two species clearly different from each other, Le. Rh. normani Allman, 1869 and Rh. striata Schepotieff, 1909. All other Recent species display a con­ siderable similarity to Rh. normani and the necessity to distinguish them is called in question by many investigators (Schepotieff, 1906; Dawydoff 1948; Thomas & .Davis, 1949; Burdon-Jones, 1954 and others). The species Rh. compacta Hincks, 1880 has recently been restored by Stebbing (1970), who concludes that Rh. compacta differs from Rh. normani mostly in the form of colonies and lack of ring-shaped part of the stolon. The following three fossil species have hitherto been described: Rh. vistulae Kozlowski, 1956 from the Danian of Poland, Rh. eocenica Tho­ mas & Davis, 1949 from the Eocene of England, and Rh. kozlowskii Kulicki, 1969 from the Callovian of Poland. The specimens of Rh. kozlowskii, described in the present paper, were etched with hydrochloric acid fTom ca1careous-marlyconcretions which occur in black and dark-gray Bathonian clays, Morrisiceras morrisi Zone (R6zycki, 1953) of Blanowice near Zawiercie. The concretions, varying in shape, are mostly spherical or ellipsoidal and fluctuate in size between a few and some scores of centimetres. Many of the concretions collected contain a macrofauna of molluscs or pieces of wood.

  • Patterns of Septal Biomineralization in Scleractinia Compared with Their 28S Rrna Phylogeny
    PBlackwell Publishingatterns Ltd. of septal biomineralization in Scleractinia compared with their 28S rRNA phylogeny: a dual approach for a new taxonomic framework JEAN-PIERRE CUIF, GUILLAUME LECOINTRE, CHRISTINE PERRIN, ANNIE TILLIER & SIMON TILLIER Accepted: 2 December 2002 Cuif, J.-P., Lecointre, G., Perrin, C., Tillier, A. & Tillier, S. (2003). Patterns of septal bio- mineralization in Scleractinia compared with their 28S rRNA phylogeny: a dual approach for a new taxonomic framework. — Zoologica Scripta, 32, 459–473. A molecular phylogeny of the Scleractinia is reconstructed from approximately 700 nucleo- tides of the 5′end of the 28S rDNA obtained from 40 species. A comparison of molecular phylogenic trees with biomineralization patterns of coral septa suggests that at least five clades are corroborated by both types of data. Agaricidae and Dendrophylliidae are found to be monophyletic, that is supported by microstructural data. Conversely, Faviidae and Caryophyl- liidae are found to be paraphyletic: Cladocora should be excluded from the faviids, whereas Eusmilia should be excluded from the caryophylliids. The conclusion is also supported by the positions, sizes and shapes of centres of calcification. The traditional Guyniidae are diphyletic, corroborating Stolarski’s hypothesis ‘A’. Some results from our most parsimonious trees are not strongly statistically supported but corroborated by other molecular studies and micro- structural observations. For example, in the scleractinian phylogenetic tree, there are several lines of evidence (including those from our data) to distinguish a Faviidae–Mussidae lineage and a Dendrophylliidae–Agaricidae–Poritidae–Siderastreidae lineage. From a methodological standpoint, our results suggest that co-ordinated studies creating links between biomineralization patterns and molecular phylogeny may provide an efficient working approach for a re- examination of scleractinian classification.

  • Deep‐Sea Coral Taxa in the U.S. Gulf of Mexico: Depth and Geographical Distribution
    Deep‐Sea Coral Taxa in the U.S. Gulf of Mexico: Depth and Geographical Distribution by Peter J. Etnoyer1 and Stephen D. Cairns2 1. NOAA Center for Coastal Monitoring and Assessment, National Centers for Coastal Ocean Science, Charleston, SC 2. National Museum of Natural History, Smithsonian Institution, Washington, DC This annex to the U.S. Gulf of Mexico chapter in “The State of Deep‐Sea Coral Ecosystems of the United States” provides a list of deep‐sea coral taxa in the Phylum Cnidaria, Classes Anthozoa and Hydrozoa, known to occur in the waters of the Gulf of Mexico (Figure 1). Deep‐sea corals are defined as azooxanthellate, heterotrophic coral species occurring in waters 50 m deep or more. Details are provided on the vertical and geographic extent of each species (Table 1). This list is adapted from species lists presented in ʺBiodiversity of the Gulf of Mexicoʺ (Felder & Camp 2009), which inventoried species found throughout the entire Gulf of Mexico including areas outside U.S. waters. Taxonomic names are generally those currently accepted in the World Register of Marine Species (WoRMS), and are arranged by order, and alphabetically within order by suborder (if applicable), family, genus, and species. Data sources (references) listed are those principally used to establish geographic and depth distribution. Only those species found within the U.S. Gulf of Mexico Exclusive Economic Zone are presented here. Information from recent studies that have expanded the known range of species into the U.S. Gulf of Mexico have been included. The total number of species of deep‐sea corals documented for the U.S.
