Received: 14 December 2012; in revised form: 25 January 2013 / Accepted: 6 February 2013 / Published: 1 March 2013 Abstract: Conotoxins are small peptides present in the venom of cone snails. The snail uses this venom to paralyze and capture prey. The constituent conopeptides display a high level of chemical diversity and are of particular interest for scientists as tools employed in neurological studies and for drug development, because they target with exquisite specificity membrane receptors, transporters, and various ion channels in the nervous system. However, these peptides are known to contain a high frequency and variability of post-translational modifications—including sometimes O-glycosylation—which are of importance for biological activity. The potential application of specific conotoxins as neuropharmalogical agents and chemical probes requires a full characterization of the relevant peptides, including the structure of the carbohydrate part. -

(UPD, Philippines) in September 2003 for the degree of Doctor of Philosophy in Marine Biology within the School of Marine Biology and Aquaculture James Cook University ABSTRACT The aim of this thesis is to describe the distribution of coral reef and shore gastropods in the Philippines, using the species rich taxa, Nerita, Clypeomorus, Muricidae, Littorinidae, Conus and Oliva. These taxa represent the major gastropod groups in the intertidal and shallow water ecosystems of the Philippines. This distribution is described with reference to the McManus (1985) basin isolation hypothesis of species diversity in Southeast Asia. I examine species-area relationships, range sizes and shapes, major ecological factors that may affect these relationships and ranges, and a phylogeny of one taxon. Range shape and orientation is largely determined by geography. Large ranges are typical of mid-intertidal herbivorous species. Triangualar shaped or narrow ranges are typical of carnivorous taxa. Narrow, overlapping distributions are more common in the central Philippines. The frequency of range sizesin the Philippines has the right skew typical of tropical high diversity systems. -

CONE SHELLS - CONIDAE MNHN Koumac 2018
Living Seashells of the Tropical Indo-Pacific Photographic guide with 1500+ species covered Andrey Ryanskiy INTRODUCTION, COPYRIGHT, ACKNOWLEDGMENTS INTRODUCTION Seashell or sea shells are the hard exoskeleton of mollusks such as snails, clams, chitons. For most people, acquaintance with mollusks began with empty shells. These shells often delight the eye with a variety of shapes and colors. Conchology studies the mollusk shells and this science dates back to the 17th century. However, modern science - malacology is the study of mollusks as whole organisms. Today more and more people are interacting with ocean - divers, snorkelers, beach goers - all of them often find in the seas not empty shells, but live mollusks - living shells, whose appearance is significantly different from museum specimens. This book serves as a tool for identifying such animals. The book covers the region from the Red Sea to Hawaii, Marshall Islands and Guam. Inside the book: • Photographs of 1500+ species, including one hundred cowries (Cypraeidae) and more than one hundred twenty allied cowries (Ovulidae) of the region; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book ACKNOWLEDGMENTS The significant part of photographs in this book were made by Jeanette Johnson and Scott Johnson during the decades of diving and exploring the beautiful reefs of Indo-Pacific from Indonesia and Philippines to Hawaii and Solomons. They provided to readers not only the great photos but also in-depth knowledge of the fascinating world of living seashells. Sincere thanks to Philippe Bouchet, National Museum of Natural History (Paris), for inviting the author to participate in the La Planete Revisitee expedition program and permission to use some of the NMNH photos. -

Magyar Malakológiai Bibliográfia (1727–2004)
01_cikkek.qxd 2005.11.21. 10:00 Page 5 MALAKOLÓGIAI TÁJÉKOZTATÓ MALACOLOGICAL NEWSLETTER 2005 23: 5–129 Magyar Malakológiai Bibliográfia (1727–2004) Varga András, Fűköh Levente & Krolopp Endre Az első Magyar Malakológiai Bibliográfia 1983-ban a Budapesten megrendezett Unitas Malacologica Kongresszus alkalmával jelent meg, Merényi László szerkesztésében. A ki- advány – Magyarországi pleisztocén és recens malakológiai bibliográfia címen – igyekezett áttekintést adni mindazokról a munkákról, melyek Magyarország területén végzett kutatá- sok eredményeit tartalmazták. Az összeállítás Magyarország alatt az adott munka megjele- nési idejének megfelelő ország területét vette alapul. Jelen összeállítás is követi ezt az alap- elvet, de a fentieken túl tartalmaz minden olyan munkát is, mely magyar szerzők nevéhez fűződően hazánkon kívüli területek malakológiai anyagának feldolgozását tartalmazza, vagy valamilyen formában kapcsolatba került a magyarországi malakológiai kutatásokkal (pl. VERDCOURT 2004). Az 1983-ban megjelent kiadványt követően egyre gyakrabban jelentkezett az igény, hogy az időközben fellelt, s a kötetből kimaradt régebbi irodalmi adatok, illetve az eltelt időszak- ban elvégzett munkák összegzése is jelenjen meg. Ennek az igénynek igyekezett eleget tenni az 1991-ben PERJÉSI György és HORVÁTH Csaba által összeállított munka, „Magyarországi pleisztocén és recens malakológiai bibliográfia (Pótlás)” a Malakológiai Tájékoztató 10. (1991) kötetében, majd ugyancsak ez a szerzőpáros készítette el az időközben megjelent újabb dolgozatok bibliográfiáját: „Magyarországi pleisztocén, quarter és recens malakológiai bibliográfia 1980-1990.” (sic!) címmel a Malakológiai Tájékoztató 11. (1992) kötetében. A fentiekben megjelent munkák óta eltelt közel negyed század ismét felvetette az igényt, hogy készüljön egy új, részben eltérő szerkesztési elveket követő munka, melynek céljai közt szerepel, hogy egyrészt összevonja a MERÉNYI, PERJÉSI & HORVÁTH féle össze- állításokat, másrészt az anyagot 2004-ig bezáróan kiegészítse az időközben megjelent dol- gozatokkal. -
A Pikkelyescsigák Élőhely-Preferenciája, Elterjedése
Crisicum 6. pp. 123-134. A pikkelyescsigák él őhely-preferenciája, elterjedése, elterjedés-története és mindezek természetvédelmi vonatkozásai Deli Tamás - Domokos Tamás - Varga András - Fehér Zoltán Abstract Habitat Preferency, Distribution, Distribution History, and the Nature Conservation Aspects of Kovacsia-Lozekia species group ( Mollusca ): The species of the highest conservation pritority of the Hungarian Mollusc (Mollusca) fauna are the Carpathian and Pannonian endemisms, among which the Kovacsia-Lozekia species group are especially interesting. Besides Kovacsia kovacsi (Varga & Pintér, 1972), that was described in Békés County, in the South Eastern part of the Graet Hungarian Plain and Lozekia transsilvanica (Westerlund, 1876) living in the southeastern foothills of the Northern Carpathians in Hungary, three species of the group live only the Eastern and South- Eastern parts of Transsylvania. About the development and distribution history of the three species molecular investigations were developed and the relationship between and inside the taxons were revealed. To our opinion the common ancestor of the species was developed in the western part of the Southern Carpathian mountains. From this place it reached the region of Bra şov to the east direction, and the Transsylvanian Island Mountain to the north direction. After it the distribution area was fragmented and from that time the three species developed separately. Accourding to our investigations it was revealed that the main distribution area of Kovacsia kovacsi is not limited to Békés County but the center of its area is in the Transsylvanian Island Mountain. This fact has not changed its conservation status, since this is an endemism with restricted distribution area. According to the genetical investigations the Hungarian population of Lozekia transsilvanica is nearly related genetically to the populations living in the centre of Transsylvania, and the genetical variability is relatively low between them. -

Biodiversita' Ed Evoluzione
Alma Mater Studiorum – Università di Bologna DOTTORATO DI RICERCA IN BIODIVERSITA’ ED EVOLUZIONE Ciclo XXIII Settore scientifico-disciplinare di afferenza: BIO/05 ZOOLOGIA MOLLUSCS OF THE MARINE PROTECTED AREA “SECCHE DI TOR PATERNO” Presentata da: Dott. Paolo Giulio Albano Coordinatore Dottorato Relatore Prof.ssa Barbara Mantovani Prof. Francesco Zaccanti Co-relatore Prof. Bruno Sabelli Esame finale anno 2011 to Ilaria and Chiara, my daughters This PhD thesis is the completion of a long path from childhood amateur conchology to scientific research. Many people were involved in this journey, but key characters are three. Luca Marini, director of “Secche di Tor Paterno” Marine Protected Area, shared the project idea of field research on molluscs and trusted me in accomplishing the task. Without his active support in finding funds for the field activities this project would have not started. It is no exaggeration saying I would not have even thought of entering the PhD without him. Bruno Sabelli, my PhD advisor, is another person who trusted me above reasonable expectations. Witness of my childhood love for shells, he has become witness of my metamorphosis to a researcher. Last, but not least, Manuela, my wife, shared my objectives and supported me every single day despite the family challenges we had to face. Many more people helped profusely. I sincerely hope not to forget anyone. Marco Oliverio, Sabrina Macchioni, Letizia Argenti and Roberto Maltini were great SCUBA diving buddies during field activities. Betulla Morello, former researcher at ISMAR-CNR in Ancona, was my guide through the previously unexplored land of non-parametric multivariate statistics. -
