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. -

ARDILA and Juan Manuel DÍAZ* Recibido el 26-III-2003. 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. -

[email protected] RESUMEN l registro de la biodiversidad marina es una tarea fundamental y la distribución de las especies está en el centro de ella. Este documento corresponde al primer registro de Titiscania limacina, un neritaceo sin concha, en Colombia. Esta especie fue encontrada Een el intermareal de un ecosistema rocoso del Parque Nacional Natural Gorgona, en la costa Pacífica. Este descubrimiento llena un vacío en la distribución de la especie en el Pacífico Oriental Tropical y hace un llamado al monitoreo de la biodiversidad, lo cual puede, dado el potencial de esta costa colombiana poco estudiada, producir más e interesantes hallazgos de nuevas especies para la región, en particular, o para la ciencia, en general. PALABRAS CLAVE: Pacífico Oriental Tropical, isla Gorgona, babosa de mar ABSTRACT ecording marine biodiversity is a fundamental task and species distributions are at the very core of it.

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. The Cassidae (Oocorythinae) appears to branched off the (Ranellinae) during The first significant radiation of the Ranellidae/Cassidaebranch took place in the Eocene. The Tonninae represents the youngest branch of the phylogenetic tree. Key words — Neomesogastropoda, Cassoidea, ecology, morphology, fossil evidence, systematics. Dr F.

Description and Classification of Late Triassic Neritimorpha (Gastropoda, Mollusca) from the St Cassian Formation, Italian Alps
Description and classification of Late Triassic Neritimorpha (Gastropoda, Mollusca) from the St Cassian Formation, Italian Alps KLAUS BANDEL Neritopsis represents the only surviving genus of an ancient group of the Neritimorpha that has no internal dissolution of its shell walls. While the two known living species have lecithotrophic early development without larval shell, Neritopsis aqabaensis n. sp. from the Gulf of Aqaba, Jordan, has a planktotrophic veliger. These living species of the ge- nus differ in their protoconch shape as well as teleoconch morphology and ornament from the Triassic species that can be considered related to Neritopsis. Neritopsidae with the modern Neritopsinae is distinguished from the Triassic Cassianopsinae n. subfam. based on the genus Cassianopsis n. gen. with three species by features of their protoconch as well as the different characters of the operculum. Zardiniopsis n. gen. differs from these by higher shell shape and a smaller more complexly ornamented protoconch. Fossariopsis has a more angular shell shape. Colubrellopsinae n. subfam. with Colubrellopsis n. gen. resembles Cassianopsis n. gen. in respect to protoconch and features of the aperture of the teleoconch, but the former has rounded whorls and an ornament of axial ribs. Among the Fedaiellidae n. fam. with smooth shells two species of Fedaiella are redefined. The characters of the inner lip of their aperture connect them with the Neritopsidae, whereas the operculum in the Fedaiellidae with concentric structure on the outside distinguishes them from neritopsids. In distinction to the groups of the Neritopsoidea members of the Dephinulopsidae have a smooth inner lip of the aperture. Here Delphinulopsinae and Platychilininae n. -

LUhtiprinters and Publishert Ann Arbor, Michigan. iQfj INTRODUCTION lilTno has not felt the urge to explore the quiet lagoon, the sandy beach, the coral reef, the Isolated sandbar, the wide muddy tidal flat, or the rock-bound coast? How many rich harvests of specimens do these yield the collector from time to time? This volume is intended to answer at least some of these questions. From the viewpoint of the biologist, artist, engineer, or craftsman, shellfish present lessons in development, construction, symme- try, harmony and color which are almost unique. To the novice an acquaint- ance with these creatures will reveal an entirely new world which, in addi- tion to affording real pleasure, will supply much of practical value. Life is indeed limitless and among the lesser animals this is particularly true.
