Book Description
Bivalves are key components of recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution.

Book Description
To some potential readers of this book the description of Biological System atics as an art may seem outdated and frankly wrong. For most people art is subjective and unconstrained by universal laws. While one picture, play or poem may be internally consistent comparison between different art products is meaningless except by way of the individual artists. On the other hand modern Biological Systematics - particularly phenetics and cladistics - is offered as objective and ultimately governed by universal laws. This implies that classifications of different groups of organisms, being the products of systematics, should be comparable irrespective of authorship. Throughout this book Minelli justifies his title by developing the theme that biological classifications are, in fact, very unequal in their expressions of the pattern and processes of the natural world. Specialists are imbibed with their own groups and tend to establish a consensus of what constitutes a species or a genus, or whether it should be desirable to recognize sub species, cultivars etc. Ornithologists freely recognize subspecies and rarely do bird genera contain more than 10 species. On the other hand some coleopterists and botanists work with genera with over 1500 species. This asymmetry may reflect a biological reality; it may express a working practicality, or simply an historical artefact (older erected genera often contain more species). Rarely are these phenomena questioned.

Book Description
This volume provides individual treatments of the major molluscan taxa. Each chapter provides an overview of the evolution, phylogeny and classification of a group of molluscs, as well as more specific and detailed coverage of their biology (reproduction, feeding and digestion, excretion, respiration etc.), their long fossil record and aspects of their natural history. The book is illustrated with hundreds of colour figures. In both volumes, concepts are summarised in colour-coded illustrations. Key selling features: Comprehensively reviews molluscan biology and evolutionary history Includes a description the anatomy and physiology of anatomical systems Up to date treatment with a comprehensive bibliography Reviews the phylogenetic history of the major molluscan lineages

Book Description
FROM THE GENERAL PREFACE: This multivolume work, The Mollusca, had its origins in the mid 1960s with the publication of two volumes entitled Physiology of Mollusca and edited by Wilbur and Yonge. In those volumes, 27 authors collaborated to summarize the status of the conventional topics of physiology as well as biochemistry, reproduction and development, and ecology. Within the past two decades, there has been a remarkable burgeoning of molluscan research generally and with it the development of new fields of investigation. During the same period, several excellent books on molluscs have appeared. However, they do not provide adequate information on the many recent advances or give the breadth of perspective of current knowledge of the phylum. Clearly, there was need for a larger work with a comprehensive treatment of major areas of molluscan research. The Mollusca, as a series of 12 volumes, attempts to fulfill this objective. Even here, practical considerations have meant that certain aspects of molluscan research have not been included.Each major area is treated by several authors, each reviewing his or her special field. The areas are structure and function, metabolic biochemistry, molecular biomechanics, environmental biochemistry, physiology, ecology, reproduction and development, neurobiology and behavior, and evolution. Throughout, the authors have given emphasis to recent advances and present status of molluscan biology. In so doing, directions of future research have become evident.The Mollusca is intended to serve several disciplines--zoology, biochemistry, physiology, and paleontology. It will prove useful to researchers and to all others with interests in molluscs.FROM THE PREFACE TO VOLUME 10: Recent events that have stimulated a great surge of investigation into the evolution of the Mollusca include the discovery of well-preserved microscopic molluscs at most levels of the Cambrian on five continents, the development of electron microscopy, the need to examine competing models of the early history of the phylum, new interest in interstitial fauna of littoral and near-littoral sands, and significant advances in our knowledge of shell ontogeny, construction, and evolution. It is timely that an up-to-date synthesis involving both paleontologists and zoologists should be published after a decade of such activity and advance when many of the long-held views on molluscan phylogeny have been overturned.This book deals with all molluscan classes except the Cephalopoda, which will be treated in Volume 12. The two books together provide an up-to-date introduction to the evolution of the Mollusca with adequate references to guide further work. They will be invaluable to specialists on molluscs, postgraduate research workers, and undergraduates with particular interests in this phylum. Authorities on the various molluscan groups were asked to express their views and to treat the subject as they wished; the book provides a valuable record of their opinions at this time.While the main groups are broadly and fully treated, focus has been narrowed toward a few selected minor groups of particular interest such as limpets, land snails, and the Anomalodesmata, in which recent work has been particularly significant.Because recent years have seen major revisions in classificatory terms, the editors have provided an outline classification into which the chapter topics fit. A New Synthesis of Recent Findings...Volume 10 examines important recent findings on the evolution of molluscs resulting from important new evidence in the fossil record. Paleontologists and zoologists present a synthetic treatment of all classes of the Mollusca (except the Cephalopods, covered in Volume 12). Topics include:molluscan origin and early evolutionthe evolution of Gastropoda and Bivalviaassessment of limpets, land snails, and the Anomalodesmata.

Book Description
Sir Charles Maurice Yonge who died in 1986 was the foremost authority on the Bivalvia and one of the greatest marine biologists of this century. The volume is a memorial to his achievements and comprises 22 papers presented at a symposium in his honour during the IX International Malacological Congress, Edinburgh, Scotland, 1986. It contains 4 sections: Evolution, Feeding and Digestion, Functional Morphology, and Ecology, and will be of interest to all students of the Mollusca.

Book Description
With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development. The contributors are Ann F. Budd, Efstathia Bura, Leo W. Buss, Mike Foote, Jörn Geister, Stephen Jay Gould, Eckart Hâkansson, Jean-Georges Harmelin, Lee-Ann C. Hayek, Jeremy B. C. Jackson, Kenneth G. Johnson, Nancy Knowlton, Scott Lidgard, Frank K. McKinney, Daniel W. McShea, Ross H. Nehm, Beth Okamura, John M. Pandolfi, Paul D. Taylor, and Erik Thomsen.
