INTRODUCTION For many years West African molluscs have been studied and described, but priority to those of size. small was always given large Only recently, very molluscs have come to the attention of authors. some They are now better known but many of them are still in awaiting study. Concerning the Rissoidae the study area and nearby, we must mention the of Verduin Amati papers (1984), (1987), Ponder (1989), Gofas (1995), Giannuzzi-Savelli et al. and Ardovini (1996), & Cossignani (2004), amongothers. MATERIAL AND METHODS in In some trips of the authors to Dakar, Senegal, 2002and 2003, numerous sediments ofbeach drift and small live species were collected.Additionalmaterialof sediments was loanedby Jacques Pelorce from 2001-2003. This was studied and compared with material from Mauritania, visited the author in 1996 in by senior companyof Jose Templado and Federico Rubio. -

Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa. -

Marine Snails of the Genus Phorcus: Biology and Ecology of Sentinel Species for Human Impacts on the Rocky Shores
DOI: 10.5772/intechopen.71614 Provisional chapter Chapter 7 Marine Snails of the Genus Phorcus: Biology and MarineEcology Snails of Sentinel of the Species Genus Phorcusfor Human: Biology Impacts and on the EcologyRocky Shores of Sentinel Species for Human Impacts on the Rocky Shores Ricardo Sousa, João Delgado, José A. González, Mafalda Freitas and Paulo Henriques Ricardo Sousa, João Delgado, José A. González, MafaldaAdditional information Freitas and is available Paulo at Henriques the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.71614 Abstract In this review article, the authors explore a broad spectrum of subjects associated to marine snails of the genus Phorcus Risso, 1826, namely, distribution, habitat, behaviour and life history traits, and the consequences of anthropological impacts, such as fisheries, pollution, and climate changes, on these species. This work focuses on discussing the ecological importance of these sentinel species and their interactions in the rocky shores as well as the anthropogenic impacts to which they are subjected. One of the main anthro- pogenic stresses that affect Phorcus species is fisheries. Topshell harvesting is recognized as occurring since prehistoric times and has evolved through time from a subsistence to commercial exploitation level. However, there is a gap of information concerning these species that hinders stock assessment and management required for sustainable exploi- tation. Additionally, these keystone species are useful tools in assessing coastal habitat quality, due to their eco-biological features. Contamination of these species with heavy metals carries serious risk for animal and human health due to their potential of biomag- nification in the food chain. -
Morphological Disparity As a Biodiversity Metric in Lower Bathyal and Abyssal Gastropod Assemblages
Evolution, 58(2), 2004, pp. 338±348 MORPHOLOGICAL DISPARITY AS A BIODIVERSITY METRIC IN LOWER BATHYAL AND ABYSSAL GASTROPOD ASSEMBLAGES CRAIG R. MCCLAIN,1,2 NICHOLAS A. JOHNSON,1,3 AND MICHAEL A. REX1 1Department of Biology, University of Massachusetts, 100 Morrissey Boulevard, Boston, Massachusetts 02125 Abstract. Studies of deep-sea biodiversity focus almost exclusively on geographic patterns of a-diversity. Few include the morphological or ecological properties of species that indicate their actual roles in community assembly. Here, we explore morphological disparity of shell architecture in gastropods from lower bathyal and abyssal environments of the western North Atlantic as a new dimension of deep-sea biodiversity. The lower bathyal-abyssal transition parallels a gradient of decreasing species diversity with depth and distance from land. Morphological disparity measures how the variety of body plans in a taxon ®lls a morphospace. We examine disparity in shell form by constructing both empirical (eigenshape analysis) and theoretical (Schindel's modi®cation of Raup's model) morphospaces. The two approaches provide very consistent results. The centroids of lower bathyal and abyssal morphospaces are statis- tically indistinguishable. The absolute volumes of lower bathyal morphospaces exceed those of the abyss; however, when the volumes are standardized to a common number of species they are not signi®cantly different. The abyssal morphospaces are simply more sparsely occupied. In terms of the variety of basic shell types, abyssal species show the same disparity values as random subsets of the lower bathyal fauna. Abyssal species possess no evident evolutionary innovation. There are, however, conspicuous changes in the relative abundance of shell forms between the two assemblages. -

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. -

Miocene Vetigastropoda and Neritimorpha (Mollusca, Gastropoda) of Central Chile
Journal of South American Earth Sciences 17 (2004) 73–88 www.elsevier.com/locate/jsames Miocene Vetigastropoda and Neritimorpha (Mollusca, Gastropoda) of central Chile Sven N. Nielsena,*, Daniel Frassinettib, Klaus Bandela aGeologisch-Pala¨ontologisches Institut und Museum, Universita¨t Hamburg, Bundesstrasse 55, 20146 Hamburg, Germany bMuseo Nacional de Historia Natural, Casilla 787, Santiago, Chile Abstract Species of Vetigastropoda (Fissurellidae, Turbinidae, Trochidae) and one species of Neritimorpha (Neritidae) from the Navidad area, south of Valparaı´so, and the Arauco Peninsula, south of Concepcio´n, are described. Among these, the Fissurellidae comprise Diodora fragilis n. sp., Diodora pupuyana n. sp., two additional unnamed species of Diodora, and a species resembling Fissurellidea. Turbinidae are represented by Cantrainea sp., and Trochidae include Tegula (Chlorostoma) austropacifica n. sp., Tegula (Chlorostoma) chilena n. sp., Tegula (Chlorostoma) matanzensis n. sp., Tegula (Agathistoma) antiqua n. sp., Bathybembix mcleani n. sp., Gibbula poeppigii [Philippi, 1887] n. comb., Diloma miocenica n. sp., Fagnastesia venefica [Philippi, 1887] n. gen. n. comb., Fagnastesia matanzana n. gen. n. sp., Calliostoma mapucherum n. sp., Calliostoma kleppi n. sp., Calliostoma covacevichi n. sp., Astele laevis [Sowerby, 1846] n. comb., and Monilea riorapelensis n. sp. The Neritidae are represented by Nerita (Heminerita) chilensis [Philippi, 1887]. The new genus Fagnastesia is introduced to represent low-spired trochoideans with a sculpture of nodes below the suture, angulated whorls, and a wide umbilicus. This Miocene Chilean fauna includes genera that have lived at the coast and in shallow, relatively warm water or deeper, much cooler water. This composition therefore suggests that many of the Miocene formations along the central Chilean coast consist of displaced sediments. -

All India Coordinated Project on Taxonomy – Mollusca , Gujarat State 1. Introduction Gujarat has a long coastline of about 1650 km, which is mainly due to the presence of two gulfs viz. the Gulf of Khambhat (GoKh) and Gulf of Kachchh (GoK). The coastline has diverse habitats such as rocky, sandy, mangroves, coral reefs etc. The southern shore of the GoK in the western India, notified as Marine National Park and Sanctuary (MNP & S), harbours most of these major habitats. The reef areas of the GoK are rich in flora and fauna; Narara, Dwarka, Poshitra, Shivrajpur, Paga, Boria, Chank and Okha are some of these pristine areas of the GoK and its surrounding environs. -

CORNISH. 1897. INTRODUCTION. During the past few years large collections of the shells of Lifu and Uvea have been made by the Rev. James and Mrs. Hadfield, and have been consigned to several Manchester conchologists. By the kindness of Messrs. R. 1 ). Darbishire, R. Cairns, and W. Moss, a very complete series of these shells has been presented to the Manchester Museum, which possesses in addition the types of the majority of the new species here described, though a few remain in Mr. Melvill's cabinet. They have been arranged for exhibition, and a list of them, with notes and descriptions of new species, was drawn up by Mr. J. Cosmo Melvill (a member of the Committee of the Manchester Museum), and Mr. R. Standen (of the Museum staff). As the collection is one of the largest and most important that has been received in this country from the Loyalty Islands, it has been thought desirable to afford the naturalists of Manchester and elsewhere an opportunity of obtaining separate copies of this catalogue, and it has therefore been reprinted from 'The Journal of Conchologv' and issued as one of the Museum Handbooks.
