Cittarium pica is a conspicuous gastropod of the rocky coastlines of the Caribbean. Given its importance in the diet of Caribbean communities, it has been over-exploited, even reaching extinction in some places, and the species has been included in the red lists of marine invertebrates in some countries. Its fishery in San Andres Island-Colombia is artisanal without any regulation, leading to a decrease in its population. Taking into account the socio-economic, cultural and ecological importance of C. pica and its vulnerability to extinction, it is urgent to develop management actions directed to increase the resilience of the species and its sustainability as a fishery resource. To assess the current population state of C. pica from San Andrés Island, we estimated size structure, sex structure, maturation size, and growth parameters, based on length-frequency data analysis. From September to December 2013, and January to March 2014, we randomly collected 458 individuals at eight representative sites of the rocky shores of the island.

												  Morphological Variations of the Shell of the Bivalve Lucina PectinataI S S N 2 3 47-6 8 9 3 Volume 10 Number2 Journal of Advances in Biology Morphological variations of the shell of the bivalve Lucina pectinata (Gmelin, 1791) Emma MODESTIN PhD of Biogeography, zoology and Ecology University of the French Antilles, UMR AREA DEV ABSTRACT In Martinique, the species Lucina pectinata (Gmelin, 1791) is called "mud clam, white clam or mangrove clam" by bivalve fishermen depending on the harvesting environment. Indeed, the individuals collected have differences as regards the shape and colour of the shell. The hypothesis is that the shape of the shell of L. pectinata (P. pectinatus) shows significant variations from one population to another. This paper intends to verify this hypothesis by means of a simple morphometric study. The comparison of the shape of the shell of individuals from different populations was done based on samples taken at four different sites. The standard measurements (length (L), width or thickness (E - épaisseur) and height (H)) were taken and the morphometric indices (L/H; L/E; E/H) were established. These indices of shape differ significantly among the various populations. This intraspecific polymorphism of the shape of the shell of P. pectinatus could be related to the nature of the sediment (granulometry, density, hardness) and/or the predation. The shells are significantly more elongated in a loose muddy sediment than in a hard muddy sediment or one rich in clay. They are significantly more convex in brackish environments and this is probably due to the presence of more specialised predators or of more muddy sediments. Keywords Lucina pectinata, bivalve, polymorphism of shape of shell, ecology, mangrove swamp, French Antilles.

Because of its variable shell it has received no less than thir- teen names, now all synonymized under the name B. granularis. We sequenced a fragment of the cox1 gene for 82 specimens covering a large part of its distribution and most type localities. Two delimitation meth- ods were applied, one based on genetic distance (ABGD) and one based on phylogenetic trees (GMYC). All analyses suggest that specimens identified as B.

Abstract: Fatty acids composition of the marine snails Phyllonotus pomum and Chicoreus brevifrons (Muricidae). Muricid species of P. pomum and C. brevifrons are of economic importance in the Caribbean. This study includes a comparative evaluation of fatty acid content in the total lipid composition of Phyllonotus pomum and Chicoreus brevifrons. Snail samples were collected during the rainy, dry and transition seasons, in Punta Arena, Sucre (Venezuela). Total lipids were extracted and the specific fatty acid contents were analyzed by gas chromatography. Lipid concentrations varied between 0.87 and 1.85%, with minimum and maximum values corresponding to C. brevifrons collected during rainy and dry seasons, respectively. In the case of total lipids, a high concentration of unsaturated fatty acids (57.21-70.05%) was observed followed by saturated fatty acids (20.33-31.94%), during all seasons. The polyunsaturated occurred in higher proportion among the unsaturated fatty acids, except for P. pomum which showed higher proportion of monounsaturated fatty acids (38.95%) dur- ing the transition season. The prevailing fatty acids were: C14:0, C16:0, C18:0, C20:1, C22:1 ω-11, C22:1 ω-9, C18:3 ω-3, C20:5 ω-3 and C22:6 ω-3, among which docosahexaenoic acid was the predominant polyunsaturated fatty acid, showing values between 4.62 and 33.11%.

												  ABSTRACT Title of Dissertation: PATTERNS INABSTRACT 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.

												  Bitasion Les Habitations-Plantations Constituent Le Creuset Historique Et Symbolique Où Fut Fondu L’Alliage Original Que Sont Les Cultures AntillaisesKelly & Bérard Ouvrage dirigé par Bitasion Les habitations-plantations constituent le creuset historique et symbolique où fut fondu l’alliage original que sont les cultures antillaises. Elles sont le berceau des sociétés créoles contemporaines qui y ont puisé tant leur forte parenté que leur Bitasion - Archéologie des habitations-plantations des Petites Antilles diversité. Leur étude a été précocement le terrain de prédilection des historiens. Les archéologues antillanistes se consacraient alors plus volontiers à l’étude des sociétés précolombiennes. Ainsi, en dehors des travaux pionniers de J. Handler et F. Lange à la Barbade, c’est surtout depuis la fin des années 1980 qu’un véritable développement de l’archéologie des habitations-plantations antillaises a pu être observé. Les questions pouvant être traitées par l’archéologie des habitations-plantations sont extrêmement riches et multiples et ne sauraient être épuisées par la publication d’un unique ouvrage. Les différents chapitres qui composent ce livre dirigé par K. Kelly et B. Bérard n’ont pas vocation à tendre à l’exhaustivité. Ils nous semblent, par contre, être représentatifs, par la variété des questions abordée et la diversité des angles d’approche, de la dynamique actuelle de ce champ de la recherche. Cette diversité est évidemment liée à celle des espaces concernés: les habitations-plantations de cinq îles des Petites Antilles : Antigua, la Guadeloupe, la Dominique, la Martinique et la Barbade sont ici étudiées. Elle est aussi, au sein d’un même espace, due à la cohabitation de différentes pratiques universitaires. Nous espérons que cet ouvrage, tout en diffusant une information jusqu’à présent trop dispersée, sera le point de départ de nouveaux travaux.

												  Structure and Function of the Digestive System in MolluscsCell and Tissue Research (2019) 377:475–503 https://doi.org/10.1007/s00441-019-03085-9 REVIEW Structure and function of the digestive system in molluscs Alexandre Lobo-da-Cunha1,2 Received: 21 February 2019 /Accepted: 26 July 2019 /Published online: 2 September 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract The phylum Mollusca is one of the largest and more diversified among metazoan phyla, comprising many thousand species living in ocean, freshwater and terrestrial ecosystems. Mollusc-feeding biology is highly diverse, including omnivorous grazers, herbivores, carnivorous scavengers and predators, and even some parasitic species. Consequently, their digestive system presents many adaptive variations. The digestive tract starting in the mouth consists of the buccal cavity, oesophagus, stomach and intestine ending in the anus. Several types of glands are associated, namely, oral and salivary glands, oesophageal glands, digestive gland and, in some cases, anal glands. The digestive gland is the largest and more important for digestion and nutrient absorption. The digestive system of each of the eight extant molluscan classes is reviewed, highlighting the most recent data available on histological, ultrastructural and functional aspects of tissues and cells involved in nutrient absorption, intracellular and extracellular digestion, with emphasis on glandular tissues. Keywords Digestive tract . Digestive gland . Salivary glands . Mollusca . Ultrastructure Introduction and visceral mass. The visceral mass is dorsally covered by the mantle tissues that frequently extend outwards to create a The phylum Mollusca is considered the second largest among flap around the body forming a space in between known as metazoans, surpassed only by the arthropods in a number of pallial or mantle cavity.

												  Mollusks of Candomblé: Symbolic and Ritualistic Importance Nivaldo a Léo Neto1,3, Robert a Voeks2, Thelma LP Dias3 and Rômulo RN Alves3*Léo Neto et al. Journal of Ethnobiology and Ethnomedicine 2012, 8:10 http://www.ethnobiomed.com/content/8/1/10 JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE RESEARCH Open Access Mollusks of Candomblé: symbolic and ritualistic importance Nivaldo A Léo Neto1,3, Robert A Voeks2, Thelma LP Dias3 and Rômulo RN Alves3* Abstract Human societies utilize mollusks for myriad material and spiritual ends. An example of their use in a religious context is found in Brazil’s African-derived belief systems. Candomblé, an Afro-Brazilian religion introduced during the 18th-19th centuries by enslaved Yoruba, includes various magical and liturgical uses of mollusks. This work inventoried the species utilized by adherents and to analyzed their symbolic and magical context. Data were obtained from Candomblé temples in two cities in the northeast of Brazil-Caruaru, in the state of Pernambuco, and Campina Grande, in the state of Paraíba. Questionnaires administered to eleven adepts revealed that at least nineteen mollusk species are being used. Shells from Monetaria moneta, M. annulus and Erosaria caputserpentis were cited by all of the interviewees. Three uses stood out: divination (jogo de búzios); utilization as ritual objects; and employment as sacrificial offerings (Igbin or Boi-de-Oxalá). The jogo de búzios (shell toss), employed in West Africa, Brazil and Cuba, is of fundamental importance to the cult, representing the means by which the faithful enter in contact with the divinities (Orixás) and consult people’s futures (Odu). The utilization of mollusks in Candomblé is strongly influenced by ancient Yoruba myths (Itãs) which, having survived enslavement and generations of captive labor, continue to guide the lives of Brazil’s African Diaspora.
