  • 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.

This study presents the first ever record of molluscan fauna from shapk beach of Jiwani. Amongst these fifty eight (58) species were found belonging to class gastropoda, twenty two (22) bivalves, one (1) scaphopod and one (1) polyplachopora comprised of thirty nine (39) families. Each collected samples was identified on species level as well as biometric data of certain species was calculated for both sites. Molluscan species similarity was also calculated between two sites. For gastropods it was remain 74 %, for bivalves 76 %, for Polyplacophora 100 % and for Scapophoda 0 %. Meanwhile total similarity of molluscan species between two sites was calculated 75 %. Notable identified species from Bandri and Shapak includes Oysters, Muricids, Babylonia shells, Trochids, Turbinids and shells belonging to Pinnidae, Arcidae, Veneridae families are of commercial significance which can be exploited for a variety of purposes like edible, ornamental, therapeutic, dye extraction, and in cement industry etc.

S. Krishnan): [email protected]. Abstract Radular morphologies of 22 species of the genus Conus from Indian coastal waters were analyzed by optical and scanning elec- tron microscopy. Although the majority of species in the present study are vermivorous, all three feeding modes known to occur in the genus are represented. Specific radular-tooth structures consistently define feeding modes. Species showing simi- lar feeding modes also show fine differences in radular structures. We propose that these structures will be of value in species identification in cases of ambiguity in other characteristics. Examination of eight discrete radular-tooth components has allowed us to classify the studied species of Conus into three groups. We see much greater inter-specific differences amongst vermivorous than amongst molluscivorous and piscivorous species. We have used these differences to provide a formula for species identification. The radular teeth of Conus araneosus, C. augur, C. bayani, C. biliosus, C. hyaena, C. lentiginosus, C. loroisii, and C. malacanus are illustrated for the first time. In a few cases our study has also enabled the correction of some erroneous descriptions in the literature.

  • 1 Northwest Florida Species List
    NORTHWEST FLORIDA SPECIES LIST This list, which contains shells found in the onshore and offshore waters of the Florida Panhandle, was prepared by the members of the Gulf Coast Shell Club. The list is arranged alphabetically by family. The numbers to the left of the shell name refer to the corresponding species as found in American Seashells, Second Edition by Dr R. Tucker Abbott. An asterisk indicates that a name change to the family, species, genus, (or all) has occurred since publication. Shells annotated with a superscript 1 indicate form names that may or may not be valid but are useful for identification. Shells annotated with a superscript 2 are shells from the 1994 Keeler and Robertson survey of the Apalachicola Marine Estuary and immediate offshore areas and represent species not currently held by GCSC members but that are deemed native to our area. Common name for the shell and its normal adult size range columns are included. There are 635 shells (including forms) on this list as of the latest update in March, 2013. Our thanks go to Dr. Harry Lee of the Jacksonville Shell Club for his assistance in this compilation. A caution: Any list of this type is subject to frequent name changes as the science involved progresses.

Thesis Committee: Names Signatures Jon-Paul Bingham (Chair) ___________________________ Harry Ako ___________________________ Cynthia Hunter ___________________________ ii Acknowledgements The author would like to take a moment to appreciate a notable few out of the army of supporters who came out during this arduously long scholastic process without whom this work would never have been. First and foremost, a “thank you” is owed to the USDA TSTAR program whose funds kept the snails alive and solvents flowing through the RP-HPLC. Likewise, the infrastructure, teachings and financial support from the University of Hawai‘i and more specifically the College of Tropical Agriculture and Human Resources provided a fertile environment conducive to cutting edge science. Through the 3 years over which this study took place, I found myself indebted to two distinct groups of students from Dr. Bingham’s lab. Those who worked primarily in the biochemical laboratory saved countless weekend RP-HPLC runs from disaster through due diligence while patiently schooling me on my deficiencies in biochemical processes and techniques.

L'expédition s'est déployée sur plusieurs fronts : récoltes sur la côte et en plongée jusqu'à 40 m environ ; dragage et chalutage au large, jusqu'à 700 m. Au total, 75 espèces de cônes ont été récoltées. De nombreuses espèces souvent communes dans l'Océan Indien Tropical ne sont représentées dans la zone d'étude que par des spécimens uniques, et nous faisons l'hypothèse que ces occurrences résultent de l'établissement occasionnel de larves planctoniques et ne sont pas l'expression de populations permanentes résidentes. Avec ces réserves, le peuplement résident de cônes du « Grand Sud » de Madagascar comprend 58 espèces, dont 10 (17%) sont des endémiques régionaux, ce qui indique qu'il s'agit d'une écorégion bien distincte, appelée "Sous-Province Toliara (Tuléar)ienne" par Lorenz, dont les contours se superposent à la carte des upwelling saisonniers.
