One is that larvae act as passive particles, being transported solely by physical means. The other idea is that through behavioral changes, larvae can alter their transport so as to improve their chances of successfully settling. Both cross-shelf and 23 hour vertical sampling of meroplanktonic larvae was conducted to investigate the hypothesis that larvae act as passive particles, being dispersed by the currents. The lengths ofbivalve larvae were also measured to determine if there were ontogenetic differences in the vertical distributions of these larvae. -
Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998
Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998 Stephen A. Grabe Environmental Supervisor David J. Karlen Environmental Scientist II Christina M. Holden Environmental Scientist I Barbara Goetting Environmental Specialist I Thomas Dix Environmental Scientist II MARCH 2003 1 Environmental Protection Commission of Hillsborough County Richard Garrity, Ph.D. Executive Director Gerold Morrison, Ph.D. Director, Environmental Resources Management Division 2 INTRODUCTION The Environmental Protection Commission of Hillsborough County (EPCHC) has been collecting samples in Middle Tampa Bay 1993 as part of the bay-wide benthic monitoring program developed to (Tampa Bay National Estuary Program 1996). The original objectives of this program were to discern the ―health‖—or ―status‖-- of the bay’s sediments by developing a Benthic Index for Tampa Bay as well as evaluating sediment quality by means of Sediment Quality Assessment Guidelines (SQAGs). The Tampa Bay Estuary Program provided partial support for this monitoring. This report summarizes data collected during 1993-1998 from the Middle Tampa Bay segment of Tampa Bay. 3 METHODS Field Collection and Laboratory Procedures: A total of 127 stations (20 to 24 per year) were sampled during late summer/early fall ―Index Period‖ 1993-1998 (Appendix A). Sample locations were randomly selected from computer- generated coordinates. Benthic samples were collected using a Young grab sampler following the field protocols outlined in Courtney et al. (1993). Laboratory procedures followed the protocols set forth in Courtney et al. (1995). Data Analysis: Species richness, Shannon-Wiener diversity, and Evenness were calculated using PISCES Conservation Ltd.’s (2001) ―Species Diversity and Richness II‖ software. -

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. -

GEIGER1 & JAMES L. GOEDERT2 1Santa Barbara Museum of Natural History, 2559 Puesta del Sol, Santa Barbara, CA 93105, USA. E-mail: [email protected] 2Burke Museum of Natural History and Culture, University of Washington, Seattle, WA 98195, USA. E-mail: jamesgoedert@outlook. com Recent and fossil global scissurellids were monographed by Geiger (2012) and additional species were recently described from Brazil (Pimenta & Geiger 2015). Here, we describe an additional fossil species from shallow water strata of the late Eocene Gries Ranch Formation in Lewis County, Washington State, USA. Marine molluscan fossils were first described from exposures of the Gries Ranch Formation along the Cowlitz River more than 100 years ago (Dickerson 1917; Van Winkle 1918) and monographed 80 years ago by Effinger (1938). Since then, many studies have included molluscan taxa from the Gries Ranch fauna (e.g., Dell’Angelo et al. 2011; Goedert & Raines 2016, and references therein). Deposition of the Gries Ranch Formation likely occurred under subtropical condi- tions (Dickerson 1917; Van Winkle 1918) at depths of less than 100 m according to Effinger (1938), although Hickman (1984) has suggested that the Gries Ranch fauna may have been transported into deep water. -

The following list has been prepared by Dr. Theodore Gill, at the request of the Smithsonian Institution, for the purpose of facilitating the arrangement and classification of the Mollusks and Shells of the National Museum ; and as frequent applica- tions for such a list have been received by the Institution, it has been thought advisable to publish it for more extended use.

The want of a complete and consistent list of the principal subdivisions of the mollusks having been experienced for some time, and such a list being at length imperatively needed for the arrangement of the collections of the Smithsonian Institution, the present arrangement has been compiled for that purpose. It must be considered simply as a provisional list, embracing the results of the most recent and approved researches into the systematic relations and anatomy of those animals, but from which innova- tions and peculiar views, affecting materially the classification, have been excluded. -
