Rev. ed. of: British prosobranch and other operculate gastropod molluscs. 1971.




The Mollusca


Book Description

The Mollusca, Volume 5: Physiology, Part 2 focuses on the biochemistry and physiology of mollusks. The selection first elaborates on the feeding biology of gastropods and feeding and digestion in Bivalvia and cephalopods. Discussions focus on feeding, digestion, feeding and digestive rhythms, feeding behavior, ontogeny of gastropod feeding biology, and feeding mechanisms. The text then examines the circulatory systems of gastropods and bivalves and circulation in cephalopods, including blood vessels and extracellular space, chemical control of the circulation, fluid mechanics of the circulation, and nature and anatomy of the circulatory system. The text takes a look at ionic regulation and water balance, excretion, and molluscan immunobiology. Topics include internal defenses of gastropods, bivalves, cephalopods, and Polyplacophorans, Monoplacophora, Cephalopoda, and Scaphopoda. The selection is a vital reference for researchers interested in the biochemistry and physiology of mollusks.




Mollusks


Book Description

Together with the influence of abiotic environmental factors, mollusks sustain the influence of species in communities. Mollusca is the largest marine phylum, comprising about 23 per cent of all the named marine organisms. This book presents current research in the study of the morphology, behaviour and ecology of mollusks. Topics discussed include the topic and trophic relationships of marine bivalves with their epi- and endobionts; chemical neuroanatomy of the cholinergic neurons in the cephalopod octopus and gastropod limax; biological and ecological aspects of the larvae of the Dreissena blanci mollusk; paleontological data on the possibility of precambrian existence of mollusks; the problem of geographical variation in freshwater gastropods; and, benthic mollusks of the Middle Parana River in Argentina.




American Opisthobranch Mollusks


Book Description

A total of 70 species are described or listed, 68 opisthobranchs and two prosobranchs (Titiscania limacina Bergh, from the Pacific side of the Canal Zone, and a Lamellaria). They were collected chiefly on the coast of Florida and neighboring seas; some are from the Gulf of Panama, where faunistic relationships with the Caribbean Sea are apparent, and from Brazil, São Paulo and Sta. Catarina. The opisthobranch faunas in the intertidal zone of the West Indies and that of Brazil, at least in the rather well known area Rio-São Paulo, have many species in common. Besides the 2 new subspecies and 18 new species (one of which, Felimare bayeri, francoisi (Risbec, 1928) for Risbecia odhneri Risbec, 1953; Anisdoris rudberghi for A. marmorata Bergh, 1898b (non A. marmorata Bergh, 1881); Aporodoris risbeci for Thordisa hilaris Bergh, 1905, var. Risbec, 1953.




Phylogeny and Evolution of the Mollusca


Book Description

"Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History
