As many habitats as possible were examined at each sites from sandy beaches, muddy sand, rocky shore, and coral reefs. A total of 306 species of gastropods were collected and had been classifi ed in53families 116genera.The most widespread species were Planaxis sulcatus (Planaxidae) and Polinices mammilla (Naticidae) found in 37 sites, followed by Echinolittorina malaccana (Littorinidae) in 35 sites. The highest diversity was 187 species in Trat whereas Koh Mark had the most abundance in this area. The lowest diversity was in Chanthaburi, 88 species, whereas Koh Nomsoa was the most abundant site.The diversity of gastropods in Chonburi was 152 species, whereas Koh Samaesarn and Koh Juang were the most abundant site. 137 species had been found in Rayong and Koh Munnai was the most abundant site. The data from this study had been compared with the resent studies in the late decade from the west coast of the Gulf of Thailand and Andaman Sea.The total gastropods in the late decade were 454 species 205 genera 69 families.

Y. Low Abstract. An annotated checklist of the Mollusca from the Australian Indian Ocean Territories (IOT) of Christmas Island (Indian Ocean) and the Cocos (Keeling) Islands is presented. The checklist combines data from all previous studies and new material collected during the recent Christmas Island Expeditions organised by the Lee Kong Chian Natural History Museum (formerly the Raffles Museum of Biodiversty Resarch), Singapore. The checklist provides an overview of the diversity of the malacofauna occurring in the Cocos (Keeling) / Christmas Island ecoregion. A total of 1,178 species representing 165 families are documented, with 760 (in 130 families) and 757 (in 126 families) species recorded from Christmas Island and the Cocos (Keeling) Islands, respectively. Forty-five species (or 3.8%) of these species are endemic to the Australian IOT. Fifty-seven molluscan records for this ecoregion are herein published for the first time. We also briefly discuss historical patterns of discovery and endemism in the malacofauna of the Australian IOT. Key words.

  • Prosobranch Gastropods of Guam

    Prosobranch Gastropods of Guam

    Micronesica 35-36:244-270. 2003 Prosobranch gastropods of Guam BARRY D. SMITH Marine Laboratory University of Guam Mangilao, Guam 96923 U.S.A. email: [email protected] Abstract—Based on records from invertebrate collections at the University of Guam, specimens cataloged at other institutions, and the published literature, there are 895 species of prosobranch gastropods from Guam. The vast majority of the species are marine, but terrestrial and aquatic prosobranchs are included. Most the species recorded to date are conspicuous, epibenthic species from shallow reef habitats, but some species have been taken from depths up to 400 m. Microgastropods less than 7 mm in size have been poorly investigated to date. Comparison of prosobranch gastropods from Guam and Enewetak reveal that some 56% of the species occurring at Enewetak are found in Guam. Introduction Molluscs have been collected in Guam since the arrival of the earliest inhabitants (Thompson, 1945). Despite the long history of European contact with the island, scant attention was given to systematic investigation of the fauna until the collections of Quoy and Gaimard (1824–1826; 1830–1834). Hidalgo (1904– 1905) was the first to produce a catalog that included molluscs from Guam, but his emphasis was mostly on the Philippine Islands fauna. This catalog was followed by a series of unpublished lists produced by shell collectors and shell club members during the last several decades. Synoptic collections of molluscs from Guam and Micronesia were started by faculty of the University of Guam in the mid-1960s. These collections are housed in the Richard E. Dickinson Memorial Mollusc Collection at the University of Guam Marine Laboratory.

    Introduced Marine and Estuarine Mollusks of North America: an End-Of-The-20Th-Century Perspective

    Journal of Shellfish Research, Vol. 11. N o. 2. 489-505. 1992 INTRODUCED MARINE AND ESTUARINE MOLLUSKS OF NORTH AMERICA: AN END-OF-THE-20TH-CENTURY PERSPECTIVE JAMES T. CARLTON Maritime Studies Program Williams College-Mystic Seaport 50 Greenmanville Avenue Mystic, Connecticut 06355 ABSTRACT A review of the introduced marine and estuarine (brackish water) bivalves and prosobranch and pulmonate gastropods of the Atlantic, Gulf and Pacific coasts of North America reveals an established fauna of 36 non-indigenous species. Sixteen species are native to temperate or tropical coasts of North America, and have been transported to regions of the continent where they did not occur in historical time; the remaining 20 species are from Europe, the Mediterranean, South America, the Indo-Pacific, and the northwestern Pacific. The movement of Pacific (Japanese) and Atlantic commercial oysters to the Pacific coast, and ship fouling, boring, and ballast water releases, have been the primary human-mediated dispersal mechanisms. Regional patterns are striking: 30 species are established on the Pacific coast, 8 on the Atlantic coast, and 1 on the Gulf coast (three species occur on both coasts); 19 (63%) of the Pacific species occur in San Francisco Bay alone. These patterns may be linked to a combination of human-mediated dispersal mechanisms and regional geological-biological Pleistocene history: at least 27 species of Japanese and Atlantic coast mollusks were introduced to the American Pacific coast by the oyster industry, in large part into geologically young regions with low native molluscan diversity. With the exception of a few species, there is little experimental elucidation of the ecological impact of the introduced marine mollusks in North America.

    Trochidae (Archaeogastropoda) from the Campanian of Torallola in northern Spain Geologisch-Paliiontologisches Institut und Museum, Universitiit Hamburg, Bundesstrasse 55, 20146 Hamburg, Germany. E-mail.·[email protected];[email protected] KrEL, S. & BANDEL, K. 2001. Trochidae (Archaeogastropoda) from the Campanian of Torallola in nothern Spain. Acta Geologica Polonica, Sl (2), 137-154. Warszawa 30 species of the archaeogastropod family Trochidae are described from the Campanian of the southern Pyrenees, 15 of them are new. The new genus Amphigibbula is introduced and the genus Chilodontoidea is renamed as Hudledonta. Apparently several trochid lineages with living species can be traced back into the Late Cretaceous. This regards the Eucyclinae, Margaritinae, and Solariellinae, and the Tegulinae with some reservations. Among the groups examined here, only the members of the Trochinae appear to be of rather different character than their mod- ern representatives. The fossil record of the Umboniinae can go far beyond that of the Late Cretaceous and connect even to Palaeozoic genera. The 15 new species are: Eucyclomphalus reminiscencius, Calliotropis torallolensis, Calliotropis seguris, Ilerdus pyrenaeus, Eucycloscala cretacea, Hudledonta nicolae, Danilia kosslerae, Margarites kasei, Margarites nielseni, Margarites kowalkei, Tectus quinteroi, Thoristella marshalli, Suavotrochus ponsi, Ethalia vinxae, and Protorotella herberti. is not infrequently the case in the carbonate environment, rock diagenesis usually has resulted in a hard limestone, The Late Cretaceous was a time when numerous from which fossils are difficult to extract. modem gastropod groups made their first appearance The sediments of the Puimanyons Olisthostrom and subsequently radiated (SOHL 1987). In contrast, near Torallola in northern Spain are the result of a archaeogastropods of this period are rarely described and series of events when entire shorelines became instable, reports on them are scattered throughout the literature.
