MEDITS Survey – Instruction Manual - Version 6 3 Preamble The MEDITS project started in 1994 within the cooperation between several research Institutes from the four Mediterranean member States of the European Union. The target was to conduct a common bottom trawl survey in the Mediterranean in which all the participants use the same gear, the same sampling protocol and the same methodology. A first manual with the major specifications was prepared at the start of the project. The manual was revised in 1995, following the 1994 survey, taking into account the methodological improvements acquired during the first survey. During the course of years, several improvements were made. A new version of the manual was issued each time it was felt necessary to make improvements to the previous protocol. In any case, each time the MEDITS co-ordination committee ensured that amendments did not disrupt the consistency of the series. The third version of this manual was edited in 1999, while the fourth one served as a manual for the surveys carried out between 2000 and 2006. The fifth version, although issued in 2007, included improvements adopted by the MEDITS group since 2005, and was the protocol followed from the 2005 surveys until 2011 due to the issue of the present version. This sixth version is an update of the 2007 MEDITS handbook, taking into consideration the evolution of the MEDITS survey within the Data Collection Framework. This version presents changes related to the reference list of species, the biological parameters to be collected, and consequently the storage data formats that have been adjusted to account for these changes. MEDITS Survey – Instruction Manual - Version 6 4 Co-ordination of the MEDITS program (2012) Co-ordination The MEDITS program is currently co-ordinated at international level by Maria Teresa Spedicato (COISPA Tecnologia&Ricerca, Italy).

  • Vulnerable Forests of the Pink Sea Fan Eunicella Verrucosa in the Mediterranean Sea
    diversity Article Vulnerable Forests of the Pink Sea Fan Eunicella verrucosa in the Mediterranean Sea Giovanni Chimienti 1,2 1 Dipartimento di Biologia, Università degli Studi di Bari, Via Orabona 4, 70125 Bari, Italy; [email protected]; Tel.: +39-080-544-3344 2 CoNISMa, Piazzale Flaminio 9, 00197 Roma, Italy Received: 14 April 2020; Accepted: 28 April 2020; Published: 30 April 2020 Abstract: The pink sea fan Eunicella verrucosa (Cnidaria, Anthozoa, Alcyonacea) can form coral forests at mesophotic depths in the Mediterranean Sea. Despite the recognized importance of these habitats, they have been scantly studied and their distribution is mostly unknown. This study reports the new finding of E. verrucosa forests in the Mediterranean Sea, and the updated distribution of this species that has been considered rare in the basin. In particular, one site off Sanremo (Ligurian Sea) was characterized by a monospecific population of E. verrucosa with 2.3 0.2 colonies m 2. By combining ± − new records, literature, and citizen science data, the species is believed to be widespread in the basin with few or isolated colonies, and 19 E. verrucosa forests were identified. The overall associated community showed how these coral forests are essential for species of conservation interest, as well as for species of high commercial value. For this reason, proper protection and management strategies are necessary. Keywords: Anthozoa; Alcyonacea; gorgonian; coral habitat; coral forest; VME; biodiversity; mesophotic; citizen science; distribution 1. Introduction Arborescent corals such as antipatharians and alcyonaceans can form mono- or multispecific animal forests that represent vulnerable marine ecosystems of great ecological importance [1–4].

The mean nucleotide diversity was found to be 0.0792. Average sequence divergence between species of Sebastidae and Scorpaenidae was 8.4%, and 6.4%. between species of the genus Scorpaena. For congeneric comparisions, the lowest genetic divergence (0.7%) was observed between S. porcus and S. notata, and the highest divergence (10.8%) was detected between S. maderensis and S. notata. High levels of nucleotide divergence were detected between species of two families, and the maximum value was found to be 14.5% between H. dactylopterus and S. elongata. The two phylogenetic methods (NJ and MP)identifiedtwomajorlineages. IntheNJtree S. elongata wasthesistergroupto S. scrofa. S. maderensis was more divergent from these groups. Another lineage contained S. porcus and S. notata. The topology of the MP tree is similar to that of the NJ tree. The pattern and degree of morphological differentiation was not congruent with the genetic differentiation. The Euclidiean distances of morphological data revealed very high morphological divergence between the two families.

  • The Echinoderm Fauna of Turkey with New Records from the Levantine Coast of Turkey
    Proc. of middle East & North Africa Conf. For Future of Animal Wealth THE ECHINODERM FAUNA OF TURKEY WITH NEW RECORDS FROM THE LEVANTINE COAST OF TURKEY Elif Özgür1, Bayram Öztürk2 and F. Saadet Karakulak2 1Faculty of Fisheries, Akdeniz University, TR-07058 Antalya, Turkey 2İstanbul University, Faculty of Fisheries, Ordu Cad.No.200, 34470 Laleli- Istanbul, Turkey Corresponding author e-mail: [email protected] ABSTRACT The echinoderm fauna of Turkey consists of 80 species (two Crinoidea, 22 Asteroidea, 18 Ophiuroidea, 20 Echinoidea and 18 Holothuroidea). In this study, seven echinoderm species are reported for the first time from the Levantine coast of Turkey. These are, five ophiroid species; Amphipholis squamata, Amphiura chiajei, Amphiura filiformis, Ophiopsila aranea, and Ophiothrix quinquemaculata and two echinoid species; Echinocyamus pusillus and Stylocidaris affinis. Turkey is surrounded by four seas with different hydrographical characteristics and Turkish Straits System (Çanakkale Strait, Marmara Sea and İstanbul Strait) serve both as a biological corridor and barrier between the Aegean and Black Seas. The number of echinoderm species in the coasts of Turkey also varies due to the different biotic environments of these seas. There are 14 echinoderm species reported from the Black Sea, 19 species from the İstanbul Strait, 51 from the Marmara Sea, 71 from the Aegean Sea and 42 from the Levantine coasts of Turkey. Among these species, Asterias rubens, Ophiactis savignyi, Diadema setosum, and Synaptula reciprocans are alien species for the Turkish coasts.

  • Abundance and Diversity of Decapod Crustaceans in the Deep-Catalan Sea (Western Mediterranean)
    JOURNAL OF NATURAL HISTORY, 1992, 26, 1305-1323 Abundance and diversity of decapod crustaceans in the deep-Catalan Sea (Western Mediterranean) J. E. CARTES and F. SARDA Institut de Ciencies del Mar, Passeig National s/n, 08039 Barcelona, Spain (Accepted 7 August 1992) The deep-slope decapod fauna of the Catalan Sea was extensively sampled with an OTSB-14 bottom trawl. A total of 67 bottom tows were taken from 1985 to 1989 at bottom depths ranging from 552 to 2261 m. Species in which abundance decreased with depth were Plesionika acanthonotus, Polycheles typhlops, Calocaris macandreae and Geryon longipes. Highest densities of Acanthephyra eximia, Stereomastis sculpta, and Nematocarcinus exilis were attained at the great­ est depths studied. Total abundance, biomass and species richness for decapod crustaceans as a whole decreased with depth. Maximum decapod biomass and diversity occurred on the upper-middle slope on soft bottoms in the .Catalan Sea and in all regions for which data were available. In the Catalan Sea, an oligotrophic area, the abundance of decapods as a group seemed to be higher than in north- Atlantic eutrophic regions. In these latter areas, other deep-sea benthic invertebrate groups, particularly ophiuroids, predominate. KEYWORDS: Decapod crustaceans, Mediterranean, abundance, biomass, diversity. Introduction The deep-sea decapod crustacean fauna in the Mediterranean has been only quali­ tatively studied (Carpine, 1970a; Reyss, 1971; Fredj and Laubier, 1985; Peres, 1985; Abello and Valladares, 1988; Cartes, 1992 and references cited). Data on abundance, biomass and on the dominant species along the deep slope are particularly scarce. The structure of bathyal decapod crustacean populations on the upper slope in the northwestern Mediterranean is relatively well known (Zariquiey Alvarez, 1968; Sarda and Palomera, 1981; Abello et al., 1988) down to a depth of 800 m, with data on species abundance and biomass also available.

Insgesamt können 24 Arten nachgewiesen werden. Tonnoidea weisen generell eine ungewöhnliche weite geographische und stratigraphische Verbreitung auf, wie sie bei anderen Gastropoden unbekannt ist. Dementsprechend sind die paratethyalen Arten meist auch in der mediterranen und der atlantischen Bioprovinz vertreten. Einige Arten treten zuerst im mittleren Miozän der Paratethys auf. Insgesamt dokumentiert die Verteilung der tonnoiden Gastropoden in der Parate- thys einen starken klimatischen Einfluss.

  • Mollusca, Gastropoda
    Contr. Tert. Quatern. Geol. 32(4) 97-132 43 figs Leiden, December 1995 An outline of cassoidean phylogeny (Mollusca, Gastropoda) Frank Riedel Berlin, Germany Riedel, Frank. An outline of cassoidean phylogeny (Mollusca, Gastropoda). — Contr. Tert. Quatern. Geo!., 32(4): 97-132, 43 figs. Leiden, December 1995. The phylogeny of cassoidean gastropods is reviewed, incorporating most of the biological and palaeontological data from the literature. Several characters have been checked personally and some new data are presented and included in the cladistic analysis. The Laubierinioidea, Calyptraeoidea and Capuloidea are used as outgroups. Twenty-three apomorphies are discussed and used to define cassoid relations at the subfamily level. A classification is presented in which only three families are recognised. The Ranellidae contains the subfamilies Bursinae, Cymatiinae and Ranellinae. The Pisanianurinae is removed from the Ranellidae and attributed to the Laubierinioidea.The Cassidae include the Cassinae, Oocorythinae, Phaliinae and Tonninae. The Ranellinae and Oocorythinae are and considered the of their families. The third the both paraphyletic taxa are to represent stem-groups family, Personidae, cannot be subdivided and for anatomical evolved from Cretaceous into subfamilies reasons probably the same Early gastropod ancestor as the Ranellidae. have from Ranellidae the Late Cretaceous.

BUIRKENROAD2 During two years of exploration of the coastal waters of Louisiana, 1929 to 1931, nine species of Penaeidae and six of Sergestidae were cap- tured. Of the Penaeidae, one (Solenocera vioscai) has not been pre- viously described, and two others, Parapenaeus longirostris (Lucas) and Trachypeneus similis (Smith), are additions to the five that have been reported from the region by previous workers. These five species, Penaeus setiferus (Linnaeus), Penaeus brasiliensis Latreille, Trachy- peneus constrictus (Stimpson) (which is here replaced by a valid record, since the former one refers to T. similis), Xiphopeneus kroyeri (Heller), and Eusicyonia dorsalis (Kingsley), are represented in the material to be discussed. The ninth species taken is an aristaeine mysis, probably Gennadas elegans (Smith) which occurred in the open gulf outside of the strictly littoral zone. Of the six Sergestidae, only two (Acetes carolinae Hansen and Lucifer faxoni Borradaile) were found within the littoral area. Preadults of four species of Sergestes-a female of S. atlanticus H.
