AVANT-PROPOS Suite à une recommandation du Plan d’Action pour la Conservation de la Végétation Marine en mer Méditerranée (adopté par les Parties contractantes à la Convention de Barcelone, en 1999), une série de symposiums scientifiques, dédiée à la végétation marine méditerranéenne, a été initiée en 2000. Cette initiative vise essentiellement à faire le point sur les données scientifiques disponibles et à promouvoir la coopération entre les spécialistes méditerranéens. Le premier symposium méditerranéen sur la végétation marine (Ajaccio, Octobre 2000) a réuni 43 participants de 15 pays méditerranéens et s’est traduit par 32 communications orales et posters. Lors des tables rondes des sujets d’importance, tels que la taxonomie dans la région et l’utilisation de la végétation marine comme outil de gestion de la zone côtière, ont été abordés. Les recommandations ont permis de promouvoir, dans le cadre du Plan d’Action pour la Méditerranée, une initiative méditerranéenne sur la Taxonomie, s’inspirant de la démarche développée, dans le cadre de la Convention sur la Diversité Biologique, au plan mondial. Le deuxième symposium (Athènes, Décembre 2003), organisé en collaboration avec le Centre Grec pour la Recherche Marine, a regroupé 67 participants issus de 15 pays méditerranéens. 40 communications orales et posters ont été présentés à cette occasion. Les groupes de travail qui se sont réunis ont mis l’accent sur la nécessité de standardiser les techniques de cartographie et de développer des outils pour la taxonomie de la végétation marine, à l’échelon méditerranéen. Le troisième symposium, programmé à Marseille, du 27 au 29 Mars 2007, en partenariat avec la Région Provence-Alpes-Côte d’Azur et l’Association Seagrass 2000 (associée au Plan d’Action pour la Conservation de la Végétation Marine en mer Méditerranée), a vu l’inscription de 120 participants provenant de 17 pays méditerranéens. Ce ne sont pas moins de 60 communications orales et posters qui devraient y être présentés. Le CAR/ASP a souhaité profiter de la présente session pour faire permettre la diffusion des résultats obtenus dans le cadre du programme Interreg III B "Mise en cohérence, développement, harmonisation et validation de méthodes d’évaluation de la qualité du milieu littoral par le suivi de l’herbier à Posidonia oceanica - POSIDONIA" à la communauté scientifique méditerranéenne. Des tables rondes permettront d’aborder des thèmes d’actualité tels que : - Quelles méthodes de cartographie et de surveillance, pour quels objectifs de gestion ? - La végétation marine de Méditerranée constitue-t-elle un outil d’évaluation de l’efficacité des stratégies (Directive Cadre sur l’Eau, Directive Stratégie Maritime) et des grands enjeux environnementaux (Horizon 2012, Initiative Horizon 2020) ? - Comment mettre en place une conservation efficace des « hots-spot » de biodiversité que représentent les formations coralligènes et autres bioconcrétionnements calcaires de Méditerranée ?

  • Octocoral Diversity of Balıkçı Island, the Marmara Sea
    J. Black Sea/Mediterranean Environment Vol. 19, No. 1: 46-57 (2013) RESEARCH ARTICLE Octocoral diversity of Balıkçı Island, the Marmara Sea Eda Nur Topçu1,2*, Bayram Öztürk1,2 1Faculty of Fisheries, Istanbul University, Ordu St., No. 200, 34470, Laleli, Istanbul, TURKEY 2Turkish Marine Research Foundation (TUDAV), P.O. Box: 10, Beykoz, Istanbul, TURKEY *Corresponding author: [email protected] Abstract We investigated the octocoral diversity of Balıkçı Island in the Marmara Sea. Three sites were sampled by diving, from 20 to 45 m deep. Nine species were found, two of which are first records for Turkish fauna: Alcyonium coralloides and Paralcyonium spinulosum. Scientific identification of Alcyonium acaule in the Turkish seas was also done for the first time in this study. Key words: Octocoral, soft coral, gorgonian, diversity, Marmara Sea. Introduction The Marmara Sea is a semi-enclosed sea connecting the Black Sea to the Aegean Sea via the Turkish Straits System, with peculiar oceanographic, ecological and geomorphologic characteristics (Öztürk and Öztürk 1996). The benthic fauna consists of Black Sea species until approximately 20 meters around the Prince Islands area, where Mediterranean species take over due to the two layer stratification in the Marmara Sea. The Sea of Marmara, together with the straits of Istanbul and Çanakkale, serves as an ecological barrier, a biological corridor and an acclimatization zone for the biota of Mediterranean and Black Seas (Öztürk and Öztürk 1996). The Islands in the Sea of Marmara constitute habitats particularly for hard bottom communities of Mediterranean origin. Ten Octocoral species were reported by Demir (1954) from the Marmara Sea but amongst them, Gorgonia flabellum was probably reported by mistake and 46 should not be considered as a valid record from the Sea of Marmara.

O Laboratorio di Zoologia e Simbiosi, DiSTeBA, Universita' di Lecce, Via Prov.le Lecce-Monteroni, 73100 Lecce, Italy. P Corresponding author, e-mail: [email protected] This paper is the ¢rst attempt to study the recruitment of Serpuloideans in a Mediterranean marine cave through the use of arti¢cial substrates placed in three di¡erent positions, from the entrance to the interior of the cave. This study provides qualitative and quantitative data concerning Serpuloidea recruitment on panels removed successively after one, three, six and 12 months of permanence in the cave. A homogeneous distribution of juveniles Spirorbidae throughout the cave axis had already been detected after one month of panel immersion. Spirorbids were recorded also on panels removed after three months as well as serpulids, which began to be detected during this sampling time, even though represented by just one species. A signi¢cantly di¡erent pattern of distribution throughout the cave axis was observed after only six months, while other serpulids were detected for the ¢rst time. The pattern of species distribution seemed to re£ect the biotic and environmental conditions of the cave. The highest serpuloidean species abundance and diversity was found on panels placed in the intermediate position within the cave.

  • Quelques Aspects Problematiques Dans La Transcription Des Toponymes Tunisiens
    QUELQUES ASPECTS PROBLEMATIQUES DANS LA TRANSCRIPTION DES TOPONYMES TUNISIENS Mohsen DHIEB Professeur de géographie (cartographie) Laboratoire SYFACTE FLSH de Sfax TUNISIE [email protected] Introduction Quelle que soit le pays ou la langue d’usage, la transcription toponymique des noms de lieux géographiques sur un atlas ou un autre document cartographique en particulier ou tout autre document d’une façon générale pose problème notamment dans des pays où il n’y a pas de tradition ou de « politique » toponymique. Il en est de même pour les contrées « ouvertes » à l’extérieur et par conséquent ayant subi ou subissant encore les influences linguistiques étrangères ou alors dans des régions caractérisées par la complexité de leur situation linguistique. C’est particulièrement le cas de la Tunisie, pays méditerranéen bien « ancré » dans l’histoire, mais aussi bien ouvert à l’étranger et subissant les soubresauts de la mondialisation, et manquant par ailleurs cruellement de politique toponymique. Tout ceci malgré l’intérêt que certains acteurs aux profils différents y prêtent depuis peu, intérêt matérialisé, entre autres manifestations scientifiques, par l’organisation de deux rencontres scientifiques par la Commission du GENUING en 2005 et d’une autre août 2008 à Tunis, lors du 35ème Congrès de l’UGI. Aussi, il s’agit dans le cadre de cette présentation générale de la situation de la transcription toponymique en Tunisie, dans un premier temps, de dresser l’état des lieux, de mettre en valeur les principales difficultés rencontrées en manipulant les noms géographiques dans leurs différentes transcriptions dans un second temps. En troisième lieu, il s’agit de proposer à l’officialisation, une liste-type de toponymes (exonymes et endonymes) que l’on est en droit d’avoir par exemple sur une carte générale de Tunisie à moyenne échelle.

  • Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism
    Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism Ryutaro Goto1,2*, Tomoko Okamoto2, Hiroshi Ishikawa3, Yoichi Hamamura4, Makoto Kato2 1 Department of Marine Ecosystem Dynamics, Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa, Chiba, Japan, 2 Graduate School of Human and Environmental Studies, Kyoto University, Kyoto, Japan, 3 Uwajima, Ehime, Japan, 4 Kure, Hiroshima, Japan Abstract The Echiura, or spoon worms, are a group of marine worms, most of which live in burrows in soft sediments. This annelid- like animal group was once considered as a separate phylum because of the absence of segmentation, although recent molecular analyses have placed it within the annelids. In this study, we elucidate the interfamily relationships of echiuran worms and their evolutionary pattern of feeding mode and sexual dimorphism, by performing molecular phylogenetic analyses using four genes (18S, 28S, H3, and COI) of representatives of all extant echiuran families. Our results suggest that Echiura is monophyletic and comprises two unexpected groups: [Echiuridae+Urechidae+Thalassematidae] and [Bone- lliidae+Ikedidae]. This grouping agrees with the presence/absence of marked sexual dimorphism involving dwarf males and the paired/non-paired configuration of the gonoducts (genital sacs). Furthermore, the data supports the sister group relationship of Echiuridae and Urechidae. These two families share the character of having anal chaetae rings around the posterior trunk as a synapomorphy. The analyses also suggest that deposit feeding is a basal feeding mode in echiurans and that filter feeding originated once in the common ancestor of Urechidae. Overall, our results contradict the currently accepted order-level classification, especially in that Echiuroinea is polyphyletic, and provide novel insights into the evolution of echiuran worms.

  • 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.

  • General Introduction and Objectives 3
    General introduction and objectives 3 General introduction: General body organization: The phylum Porifera is commonly referred to as sponges. The phylum, that comprises more than 6,000 species, is divided into three classes: Calcarea, Hexactinellida and Demospongiae. The latter class contains more than 85% of the living species. They are predominantly marine, with the notable exception of the family Spongillidae, an extant group of freshwater demosponges whose fossil record begins in the Cretaceous. Sponges are ubiquitous benthic creatures, found at all latitudes beneath the world's oceans, and from the intertidal to the deep-sea. Sponges are considered as the most basal phylum of metazoans, since most of their features appear to be primitive, and it is widely accepted that multicellular animals consist of a monophyletic group (Zrzavy et al. 1998). Poriferans appear to be diploblastic (Leys 2004; Maldonado 2004), although the two cellular sheets are difficult to homologise with those of the rest of metazoans. They are sessile animals, though it has been shown that some are able to move slowly (up to 4 mm per day) within aquaria (e.g., Bond and Harris 1988; Maldonado and Uriz 1999). They lack organs, possessing cells that develop great number of functions. The sponge body is lined by a pseudoepithelial layer of flat cells (exopinacocytes). Anatomically and physiologically, tissues of most sponges (but carnivorous sponges) are organized around an aquiferous system of excurrent and incurrent canals (Rupert and Barnes 1995). These canals are lined by a pseudoepithelial layer of flat cells (endopinacocytes).Water flows into the sponge body through multiple apertures (ostia) General introduction and objectives 4 to the incurrent canals which end in the choanocyte chambers (Fig.
