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. -

ZooKeys 963: 1–36. https://doi.org/10.3897/zookeys.963.52234 Abstract An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel because it connects the South Pacific and Atlantic Oceans. These characteristics make it an interesting area for marine research; thus, the Strait of Magellan has histori- cally been the area with the greatest research effort within the province. -

McLean, former Curator of Malacology at the Natural History Museum of Los Angeles County is provided. It is complemented with a full bibliography and list of 344 taxa named by him and co-authors (with type information and current status), as well as 40 patronyms. Biography James Hamilton McLean was born in Detroit, Michigan, on June 17, 1936. The McLean family moved to Dobbs Ferry, New York, on the Hudson River in 1940, a short train ride and subway ride away from the American Museum of Natural History (AMNH). His brother Hugh recalled that, “AMNH became the place of choice to go to whenever we could get someone to take us. Those visits opened our eyes to the variety and possibilities of what was out there, waiting for us to discover and collect.” From an early age James seemed destined to have a career at a museum (Figs 1–2). -

ANN ARBOR, MICHIGAN J 1937 Copyright 1937 MAXWELL SMITH PUNTZO IN D,S.A. LUhoprinted by Edwards B'olheri. Inc.. LUhtiprinters and Publishert Ann Arbor, Michigan. iQfj INTRODUCTION lilTno has not felt the urge to explore the quiet lagoon, the sandy beach, the coral reef, the Isolated sandbar, the wide muddy tidal flat, or the rock-bound coast? How many rich harvests of specimens do these yield the collector from time to time? This volume is intended to answer at least some of these questions. From the viewpoint of the biologist, artist, engineer, or craftsman, shellfish present lessons in development, construction, symme- try, harmony and color which are almost unique. To the novice an acquaint- ance with these creatures will reveal an entirely new world which, in addi- tion to affording real pleasure, will supply much of practical value. Life is indeed limitless and among the lesser animals this is particularly true. -
