  • Faunistic Assemblages of a Sublittoral Coarse Sand Habitat of the Northwestern Mediterranean

SUMMARY: The sublittoral megabenthic assemblages of a northwestern Mediterranean coarse sandy beach exploited for the bivalve Callista chione were studied. The spatial and bathymetric variability of its distinctive faunal assemblages was characterised by quantitative sampling performed with a clam dredge. The taxa studied were Mollusca Bivalvia and Gastropoda, Crustacea Decapoda, Echinodermata and Pisces, which accounted for over 99% of the total biomass. Three well- differentiated species assemblages were identified: (1) assemblage MSS (Medium Sand Shallow) in medium sand (D50=0.37 mm) and shallow waters (mean depth =6.5 m), (2) assemblage CSS (Coarse Sand Shallow) in coarse sand (D50=0.62 mm) in shallow waters (mean depth =6.7 m), and (3) assemblage CSD (Coarse Sand Deep) in coarse sand (D50=0.64 mm) in deeper waters (mean depth =16.2 m). Assemblage MSS was characterised by the codominance of the bivalves Mactra stultorum and Acanthocardia tuberculata. C. chione was dominant in both density and biomass in assemblages CSS and CSD.

En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles). Ao final inclúese unha listaxe de referencias bibliográficas que foron utilizadas para a elaboración do presente documento. Nalgunhas desas referencias recolléronse ou propuxéronse nomes galegos para os moluscos, quer xenéricos quer específicos. Outras referencias achegan nomes para os moluscos noutras linguas, que tamén foron tidos en conta. Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos).

  • Biogeographical Homogeneity in the Eastern Mediterranean Sea. II
    Vol. 19: 75–84, 2013 AQUATIC BIOLOGY Published online September 4 doi: 10.3354/ab00521 Aquat Biol Biogeographical homogeneity in the eastern Mediterranean Sea. II. Temporal variation in Lebanese bivalve biota Fabio Crocetta1,*, Ghazi Bitar2, Helmut Zibrowius3, Marco Oliverio4 1Stazione Zoologica Anton Dohrn, Villa Comunale, 80121, Napoli, Italy 2Department of Natural Sciences, Faculty of Sciences, Lebanese University, Hadath, Lebanon 3Le Corbusier 644, 280 Boulevard Michelet, 13008 Marseille, France 4Dipartimento di Biologia e Biotecnologie ‘Charles Darwin’, University of Rome ‘La Sapienza’, Viale dell’Università 32, 00185 Roma, Italy ABSTRACT: Lebanon (eastern Mediterranean Sea) is an area of particular biogeographic signifi- cance for studying the structure of eastern Mediterranean marine biodiversity and its recent changes. Based on literature records and original samples, we review here the knowledge of the Lebanese marine bivalve biota, tracing its changes during the last 170 yr. The updated checklist of bivalves of Lebanon yielded a total of 114 species (96 native and 18 alien taxa), accounting for ca. 26.5% of the known Mediterranean Bivalvia and thus representing a particularly poor fauna. Analysis of the 21 taxa historically described on Lebanese material only yielded 2 available names. Records of 24 species are new for the Lebanese fauna, and Lioberus ligneus is also a new record for the Mediterranean Sea. Comparisons between molluscan records by past (before 1950) and modern (after 1950) authors revealed temporal variations and qualitative modifications of the Lebanese bivalve fauna, mostly affected by the introduction of Erythraean species. The rate of recording of new alien species (evaluated in decades) revealed later first local arrivals (after 1900) than those observed for other eastern Mediterranean shores, while the peak in records in conjunc- tion with our samplings (1991 to 2010) emphasizes the need for increased field work to monitor their arrival and establishment.

These objects shell-shaped objects visually or haptically. A physical object have a shell-shaped form for several reasons: the software space was generated by varying three shape parameters.

Complete Peer review History: http://www.sciencedomain.org/review-history/23116 Received 24th November 2017 th Original Research Article Accepted 6 February 2018 Published 10th February 2018 ABSTRACT I report an unexpected negative covariance occurring between two major parameters governing shell growth in marine bivalves, especially within the order Veneroida. This relationship is highlighted, here, considering a set of forty, rather common species of clams collected from French coasts. Interestingly, this negative covariance has two (geometrically related) consequences on the pattern of variation of shell shape at the inter-specific level: (i) An extended range of variation of shell elongation ‘E’ is made compatible with. (ii) A severely restricted range of variation of the ventral convexity ‘K’ of the shell contour. I suggest that: (i) The extended range of interspecific variation of the shell elongation ‘E’ results from a trend towards larger differentiation between species according to this functionally important parameter E, while, in contrast, (ii) The strongly restricted range of variation of the ventral convexity ‘K’ of the shell contour might arguably result from a common need for improved shell resistance, face to mechanical solicitations from the environment, either biotic or abiotic.
