Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.

South Carolina Department of Natural Resources
FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas. -

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. -

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.

Spread of the Slipper Limpet Crepidula Fornicata (L. 1758) in Europe
SCI. MAR., 61 (Sup 2): 109-118 SCIENTIA MARINA 1997 ECOLOGY OF MARINE MOLLUSCS. J.D. ROS and A. GUERRA (eds.) Spread of the slipper limpet Crepidula fornicata (L. 1758) in Europe. Current state and consequences* MICHEL BLANCHARD Laboratoire d'Écologie. Institut Français de Recherche et d'Exploitation de la Mer. BP 70-Plouzané-29280. France. SUMMARY: The present distribution of the slipper limpet Crepidula fornicata in Europe is described in detail for each country, and an overview provided thanks to new information. Main observations of introduction and spread, obtained from the literature, are discussed. For most of them, we observe that both aspects are due to oyster harvesting and farming. In the most heavily infested areas (France, England, the Netherlands), activities of dredging, harvesting and oyster farming have been disrupted. In France, these activities are so much hampered that treatment methods are now developed. Key words: Slipper limpet, Crepidula fornicata, invasions, Europe. RESUMEN: EXPANSIÓN DE LA SEBA CREPIDULA FORNICATA (L., 1758) EN EUROPA. SITUACIÓN ACTUAL Y CONSECUENCIAS. – Se presenta la distribución actual de la seba (Crepidula fornicata) en Europa, para cada país, a través de las informaciones más recientes. Se discuten las principales observaciones sobre la introducción y proliferación de esta especie, obtenidas de la bibliografía. En la mayoría, la ostreicultura es responsable de ambas fases. En las áreas más afectadas (Francia, Inglaterra, Holanda), el dragado y la ostreicultura se han visto perturbadas. El impacto de esta especie introducida sobre las activida- des marisqueras es muy importante, por lo que se deberían desarollar medios de erradicación.
