    ABSTRACT Title of Dissertation: PATTERNS IN

    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

Aceptado el 5-VII-2003 ABSTRACT Among the biological material collected during the 1998-2001 “INVEMAR-Macrofauna” campaigns aboard the R/V Ancón along the upper zone of the continental slope of the Colombian Caribbean, at depths ranging from 200 to 520 m, a total of 104 gastropod species were obtained. Besides 18 not yet identified species, but including one recently described new species ( Armina juliana Ardila and Díaz, 2002), 48 species were not pre - viously known from Colombia, 18 of which were also unknown from the Caribbean Sea. Of the 36 families represented, Turridae was by far the richest in species (26 species). An annotated list of the taxa recorded is provided, as well as illustrations of those recorded for the first time in the area. RESUMEN Entre el material biológico colectado en 1998-2001 durante las campañas “INVEMAR- Macrofauna” a bordo del B/I Ancón , a profundidades entre 200 y 520 m, se obtuvo un total de 104 especies de gasterópodos. Aparte de 18 especies cuya identificación no ha sido completada, pero incluyendo una especie recientemente descrita ( Armina juliana Ardila y Díaz, 2002), 48 especies no habían sido registradas antes en aguas colombia - nas y 18 de ellas tampoco en el mar Caribe.

E-mail: [email protected] Summary: An exceptional species richness for Mollusca was found on Avempace bank (349-365 m), Djibouti group, Albo- ran Sea, where the most abundant species was the crinoid Leptometra phalangium. A sample of sediment sieved on a 0.5- mm mesh yielded 156 species of molluscs (83 live-taken, 1772 specimens) with a high Shannon-Wiener diversity index (H’(log2)=3.60). The dominant mollusc was Limopsis aurita and the six most common species accounted for 77% of the specimens. On the other hand, 42 species were represented by only one or two specimens. Two species are described as new, three more are first findings in the Mediterranean and two are first findings in Iberian waters. One-third of the species have not been reported from the neighbouring, well-explored Alboran Island platform.

To date, this is the first occur- 5 rence of such type of specialized deep-water cold-seep communities recorded from this key region, before documented in the Mediterranean as rather disjunct findings in its eastern and westernmost basins. The thiotrophic chemosymbiotic organisms recovered from this area include empty tubes of the vestimentiferan Lamellibrachia sp., loose and articulated shells of lucinids (Lucinoma kazani, Myrtea amorpha), vesi- 10 comyids (Isorropodon perplexum), and gastropods (Taranis moerchi).

Among the coasts of Turkey, the highest number of molluscan species was recorded from the Aegean Sea (825 species), followed by the Levantine Sea (807 species), Sea of Marmara (537 species), and the Black Sea (155 species). Of the 1065 mollusc taxa, 118 species are alien ones that originated outside the Mediterranean Sea. Among the listed species, Timoclea roemeriana (Bivalvia), and Sepiola ligulata and Abraliopsis morisii (both from Cephalopoda) are new records for the Turkish mollusc fauna, 11 species of the classes Polyplacophora, Gastropoda, and Bivalvia (Leptochiton boettgeri, Cerithium protractum, Similiphora similior, Cerithiopsis diadema, Rissoa guerinii, Crepidula moulinsii, Crepidula unguiformis, Bela zenetouae, Doto coronata, Lima marioni, and Limaria loscombi) are new reports for the Levantine coast of Turkey, and 2 gastropod species (Acirsa subdecussata and Monotygma lauta) are new reports for the Aegean coast of Turkey.

Chemosynthetic communities were observed and sampled on six mud volcanoes and along a fault scarp. The communities were dominated by bivalves of particularly small size, belonging to families commonly found at seeps (Mytilidae, Vesicomyidae, Thyasiridae) and to Lucinidae mostly encountered in littoral sulfide-rich sediments and at the shallowest seeps.

ORCID iD: http://orcid.org/0000-0002-6571-4720 Summary: A checklist of marine Mollusca recorded in Spanish jurisdictional waters is presented, based on a thorough lit- erature search and a limited input of recent field work. The list is detailed according to the five demarcations of the Marine Strategy Framework Directive (NOR, Spanish north coast; SUR, Spanish coast of the Gulf of Cádiz; ESAL, Strait of Gi- braltar and Alboran Sea; LEBA, East coast of Spain and Balearic Islands; CAN, the Canary Islands). The list differentiates coastal species living from the supralittoral zone to the shelf break, deep-sea benthic or demersal species, and holoplanktonic species, and also distinguishes between non-indigenous species and species endemic to a particular demarcation.
