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.

Marine Biodiversity of an Eastern Tropical Pacific Oceanic Island, Isla Del Coco, Costa Rica

Abstract: Isla del Coco (also known as Cocos Island) is an oceanic island in the Eastern Tropical Pacific; it is part of the largest national park of Costa Rica and a UNESCO World Heritage Site. The island has been visited since the 16th Century due to its abundance of freshwater and wood. Marine biodiversity studies of the island started in the late 19th Century, with an intense period of research in the 1930’s, and again from the mid 1990’s to the present. The information is scattered and, in some cases, in old publications that are difficult to access. Here I have compiled published records of the marine organisms of the island. At least 1688 species are recorded, with the gastropods (383 species), bony fishes (354 spp.) and crustaceans (at least 263 spp.) being the most species-rich groups; 45 species are endemic to Isla del Coco National Park (2.7% of the total). The number of species per kilometer of coastline and by square kilometer of seabed shallower than 200m deep are the highest recorded in the Eastern Tropical Pacific. Although the marine biodiversity of Isla del Coco is relatively well known, there are regions that need more exploration, for example, the south side, the pelagic environments, and deeper waters. -

Sambaquis As a Proxies of Late Holocene Mollusk Diversity on the Coast of Rio De Janeiro, Brazil

Statistical analysis were done using Taxonomic Dis- tinctness tests and Trophic Diversity inferences. No statistical significant differences were found between past (sambaquis) and present day inventories of malacofauna. It is concluded that sam- baquis can be valuable proxies of mollusks biodiversity from Late Holocene. Furthermore, it is supported that the incorporation of information from archaeozoological vestiges to biodiversity studies can bring a historical and evolutionary perspective for the field.

Biogeography and Biodiversity of Gastropod Molluscs from the Eastern Brazilian Continental Shelf and Slope
Lat. Am. J. Aquat. Res., 37(2): 143-159, 2009 Biogeography and biodiversity of shelf gastropods 143 DOI: 10.3856/vol37-issue2-fulltext-3 Research Article Biogeography and biodiversity of gastropod molluscs from the eastern Brazilian continental shelf and slope Gabriela Benkendorfer1 & Abílio Soares-Gomes1 1Marine Biology Department, Universidade Federal Fluminense, P.O.Box 100.644, Niterói, RJ, Brazil ABSTRACT. Biogeographic distributional patterns of gastropods are proposed based on the species’ geo- graphic and bathymetric distribution. Samples were collected along the Brazilian continental margin between 18° S and 23° S, at 37 stations with depths from 20 m to 1,330 m. The analysis of the biogeographic distribu- tion patterns confirmed the existence of a transitional zone from tropical to subtropical waters in the area of both the continental shelf and slope, suggesting a relationship with water mass circulation. We observed a high species turnover rate between the shelf and slope. The analysis of gastropod species distribution revealed a similar pattern on the shelf and slope and a large difference between shallow and deep-water faunas. Keywords: macrobenthos, continental margins, geographical distribution, vertical distribution, soft bottoms, Brazil, southwestern Atlantic Ocean. Biogeografía y biodiversidad de moluscos gastrópodos de la plataforma y talud continental brasileño RESUMEN. Los patrones de distribución biogeográfica de gastrópodos fueron propuestos basados en la dis- tribución geográfica y batimétrica de las especies. Los muestreos fueron realizados en el margen continental brasileño entre 18°S y 23°S, en 37 estaciones de 20 m a 1.330 m de profundidad. El análisis de los patrones de distribución biogeográfica confirmó la existencia de una zona de transición de aguas tropicales a aguas subtro- picales, que se encuentra en la zona de la plataforma continental y también en la zona del talud continental, es- to puede sugerir una relación con la circulación de las masas de agua.
