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. -

Conopeptide Production through Biosustainable Snail Farming A THESIS SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI‘I AT MĀNOA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN MOLECULAR BIOSCIENCES AND BIOENGINEERING DECEMBER 2012 By Jeffrey W.

Milisen Student ID#: 1702-1176 Degree: MS Field: Molecular Biosciences and Bioengineering Graduation Date: December 2012 Title: Conopeptide Production through Biosustainable Snail Farming We certify that we have read this Thesis and that, in our opinion, it is satisfactory in scope and quality as a Thesis for the degree of Master of Science in Molecular Biosciences and Bioengineering. Thesis Committee: Names Signatures Jon-Paul Bingham (Chair) ___________________________ Harry Ako ___________________________ Cynthia Hunter ___________________________ ii Acknowledgements The author would like to take a moment to appreciate a notable few out of the army of supporters who came out during this arduously long scholastic process without whom this work would never have been. First and foremost, a “thank you” is owed to the USDA TSTAR program whose funds kept the snails alive and solvents flowing through the RP-HPLC. Likewise, the infrastructure, teachings and financial support from the University of Hawai‘i and more specifically the College of Tropical Agriculture and Human Resources provided a fertile environment conducive to cutting edge science. Through the 3 years over which this study took place, I found myself indebted to two distinct groups of students from Dr. Bingham’s lab. Those who worked primarily in the biochemical laboratory saved countless weekend RP-HPLC runs from disaster through due diligence while patiently schooling me on my deficiencies in biochemical processes and techniques. -

Western Atlantic Cones 1 Why Study One Genus of Molluscs From
Western Atlantic Cones Why study one Genus of molluscs from one area? Such a topic would prove limited and brief. The opposite happens to be true in this case. The topography of the Western Atlantic has created many sub-regions and pockets that have, in turn, given rise to today's exciting Conidae. To make this book enjoyable and useful to the collector I've strived for a balance between text and photographs. This book is written for collectors. Shell collecting happens to be a hobby that marries science and beauty. As I have advanced with my collection, my desire to find out more has grown. The diverse cones of the Western Atlantic have provided me a continuing source of fascination for many years. The scope of these shells range from the ultra-rare to the abundant. Similarly, the color and patterns of some Conus complexes are nothing short of amazing. Please enjoy this book. I have had great pleasure in preparing it. Happy Collecting, Matthew H. Grote 1 Western Atlantic Cones FOREWORD It is the aim of this book to discuss the living Conus species known from the Western Atlantic. This area includes both the subtropic Carolinian Province and the tropical Caribbean Province. The northern borders of this area include the coast of North Carolina out to Bermuda. They further extend southward to include the Gulf of Mexico and the Caribbean Sea. Cones can be found as far south as northern Argentina, so this represents the southern limit. To the delight of collectors many new cones have been recently describe. -

Tucker include it in a regular number and its obvious interest certainly advised against splitting it into several consecutive issues. Pre- senting it as Special Issue #14A was the natural solution for those problems. The need for a revision of Western Atlantic Cones has been long felt. Every once in a while we do indeed hear that some- one or other is working on it, but no release dates loom in the horizon. This of course means that every contribution to a bet- ter understanding of that most interesting geographical zone is quite welcome. Hence, we heartily welcome John Tucker’s extensive comments on the series of articles published by Danker Vink back in the 80s, as an important piece of information that will certainly help us to find our way amidst what is certainly a rather com- plicated issue. I personally thank John for submitting this paper to TCC and I hope that everybody will enjoy it.

THE CONE COLLECTOR #26 December 2014 THE Note from CONE the Editor COLLECTOR Dear friends, Editor The year 2014 has been quite rich with interesting events and António Monteiro publications for Cone lovers. Layout For one thing, we had our 3rd International Cone Meeting, André Poremski held in Madrid in the first weekend in October, and what a Contributors great meeting it was! The organization was flawless, the talks Michel Balleton were mightily interesting, the ambiance was excellent, the Bill Fenzan weather was brilliant. What more can one ask for? You will Joaquin M.

In our usual section “Who’s Who in Cones”, you will get to know Gavin Malcolm a little better. As usual, there is also a detailed list of recent publications and newly described taxa. Several other articles will, I hope, be of interest to everybody. So, without further ado, enjoy the new issue of TCC!

Anderson* and Gyula Bokor 1CBRN Consultant, Randolph, MA, USA 2Staff Psychiatrist, Taunton State Hospital, Taunton, MA, USA Abstract Cone snails are predatory marine animals that kill their prey with powerful venom. Conotoxins are a pharmacologically and chemically diverse group of toxins found in the venom. A number of species of cone snails, such as Conus geographus, are deadly to humans. Conotoxins affect numerous neurotransmitter receptors and ion channels in the body. The receptors impacted include nicotinic, adrenergic, NMDA, and serotonergic. Ion channels altered include sodium, potassium and calcium. The most lethal effect of conotoxins to humans is muscle paralysis of the diaphragm causing respiratory arrest. Numerous conotoxins are being used as research tools or being explored as therapeutic drugs. Concerns in the homeland security field exist that certain conotoxins could be weaponized and used an aerosol. Conotoxins at risk of terrorist use include α-conotoxins, κ-conotoxins and δ-conotoxins. Most conotoxins are not a bioterrorism threat. The Cone Snails maris, Conus omaria, Conus magus, Conus striatus, Conus tulipa, and Conus textile [9]. Conus geographus is the most lethal to humans The cone snail is a marine predatory snail that uses powerful [9].
