This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Available in PDF, EPUB and Kindle. Book excerpt: "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

Download or read book Biology and Evolution of the Mollusca Volume 1 written by Winston Frank Ponder and published by CRC Press. This book was released on 2019-11-18 with total page 1524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molluscs comprise the second largest phylum of animals (after arthropods), occurring in virtually all habitats. Some are commercially important, a few are pests and some carry diseases, while many non-marine molluscs are threatened by human impacts which have resulted in more extinctions than all tetrapod vertebrates combined. This book and its companion volume provide the first comprehensive account of the Mollusca in decades. Illustrated with hundreds of colour figures, it reviews molluscan biology, genomics, anatomy, physiology, fossil history, phylogeny and classification. This volume includes general chapters drawn from extensive and diverse literature on the anatomy and physiology of their structure, movement, reproduction, feeding, digestion, excretion, respiration, nervous system and sense organs. Other chapters review the natural history (including ecology) of molluscs, their interactions with humans, and assess research on the group. Key features of both volumes: up to date treatment with an extensive bibliography; thoroughly examines the current understanding of molluscan anatomy, physiology and development; reviews fossil history and phylogenetics; overviews ecology and economic values; and summarises research activity and suggests future directions for investigation. Winston F Ponder was a Principal Research Scientist at The Australian Museum in Sydney where he is currently a Research Fellow. He has published extensively over the last 55 years on the systematics, evolution, biology and conservation of marine and freshwater molluscs, as well as supervised post graduate students and run university courses. David R. Lindberg is former Chair of the Department of Integrative Biology, Director of the Museum of Paleontology, and Chair of the Berkeley Natural History Museums, all at the University of California. He has conducted research on the evolutionary history of marine organisms and their habitats on the rocky shores of the Pacific Rim for more than 40 years. The numerous elegant and interpretive illustrations were produced by Juliet Ponder.

Book excerpt: 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.

Download or read book Reproduction of Marine Invertebrates V4 written by Arthur Giese and published by Elsevier. This book was released on 2012-12-02 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Marine Invetebrates, Volume IV Molluscs: Gastropods and Cephalopods describes the wide range of structural complexity and diverse modes of reproduction of gastropods and cephalopods. Each chapter discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of different group of gastropods and cephalopods, including prosobranchia, opisthobranchia, pulmonata, nautiloidea, decapoda, and octopoda. Gastropods are among the most conspicuous sea animals, and species of limpets, snails, and slugs are found in all marine habitats. Cephalopods are active and important marine predators, ranging from archaic nautiloids to more recent pelagic decapods and benthic octopods, which are often considered to be one of the apexes of invertebrate evolution. They are all gonochoric and reproduce only by sexual means. All have intricate courtship behavior and derived developmental patterns. Marine biologists and researchers, scientists, and developmental biologists will find this book invaluable.

Book excerpt: The Mollusca, Volume 7: Reproduction presents the significant features of reproduction for one of the significant major molluscan groups. This book reviews the reproductive biology of land snails, which offers the basis for making fascinating comparisons with other terrestrial groups in illustrating how evolutionary various groups solved their common problem of laying eggs. Organized into six chapters, this volume begins with an overview of the reproductive biology of prosobrach gastropods. This text then provides a comparative morphology of land snail reproductive anatomy. Other chapters consider the endocrine control of the female reproductive activity of Lymnaea stagnalis. This book discusses as well the transition in intraspecific and interspecific sexuality. The final chapter deals with cephalopod reproductive biology. This book is a valuable resource for readers who are in need of more appropriate animal systems for solving research problems pertaining to general reproduction, cytology, sex determination, biochemistry, gamete biology, neuroendocrinology, and evolutionary biology.

Download or read book Reproductive Biology of Invertebrates Accessory Sex Glands written by and published by John Wiley & Sons. This book was released on 1993-03-02 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive Biology of Invertebrates Volume III Accessory Sex Glands Edited by K. G. Adiyodi Accessory Sex Glands is the third volume in the encyclopaedic series and provides very valuable information, some hitherto unpublished, on the distribution, structure, origin physiology, biochemistry, pharmacology and evolution of the accessory sex glands in different groups of invertebrates. Volumes I and II of this series (published by Wiley) have given detailed accounts of the structure, origin, composition and physiology of female and male gametes and also provided some information on the mechanisms controlling their production. The secretions of accessory sex glands are indispensable for several key aspects of gamete physiology and for successful fertilization and development in many internally fertilizing invertebrates. Interestingly enough, accessory sex gland secretions are produced, in some species at least, under the influence of gonadotrophic hormones as are the gametes themselves. The data on invertebrate accessory sex glands are scattered in various journals and have not been so far collected, critically evaluated and published in book form. This volume thus fills a void and serves as an indispensable corollary and companion to the two volumes that have already appeared on gametology in the series.

Download or read book The Oxford Handbook of Invertebrate Neurobiology written by John H. Byrne and published by Oxford University Press. This book was released on 2019-01-29 with total page 1304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invertebrates have proven to be extremely useful model systems for gaining insights into the neural and molecular mechanisms of sensory processing, motor control and higher functions such as feeding behavior, learning and memory, navigation, and social behavior. A major factor in their enormous contributions to neuroscience is the relative simplicity of invertebrate nervous systems. In addition, some invertebrates, primarily the molluscs, have large cells, which allow analyses to take place at the level of individually identified neurons. Individual neurons can be surgically removed and assayed for expression of membrane channels, levels of second messengers, protein phosphorylation, and RNA and protein synthesis. Moreover, peptides and nucleotides can be injected into individual neurons. Other invertebrate model systems such as Drosophila and Caenorhabditis elegans offer tremendous advantages for obtaining insights into the neuronal bases of behavior through the application of genetic approaches. The Oxford Handbook of Invertebrate Neurobiology reviews the many neurobiological principles that have emerged from invertebrate analyses, such as motor pattern generation, mechanisms of synaptic transmission, and learning and memory. It also covers general features of the neurobiology of invertebrate circadian rhythms, development, and regeneration and reproduction. Some neurobiological phenomena are species-specific and diverse, especially in the domain of the neuronal control of locomotion and camouflage. Thus, separate chapters are provided on the control of swimming in annelids, crustaea and molluscs, locomotion in hexapods, and camouflage in cephalopods. Unique features of the handbook include chapters that review social behavior and intentionality in invertebrates. A chapter is devoted to summarizing past contributions of invertebrates to the understanding of nervous systems and identifying areas for future studies that will continue to advance that understanding.

Download or read book Between Pacific Tides written by Edward Flanders Ricketts and published by Stanford University Press. This book was released on 1985 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the classic works of marine biology, a favorite for generations, has now been completely revised and expanded. Between Pacific Tides is a book for all who find the shore a place of excitement, wonder, and beauty, and an unsurpassed introductory text for both students and professionals. This book describes the habits and habitats of the animals that live in one of the most prolific life zones of the world--the rocky shores and tide pools of the Pacific Coast of the United States. The intricate and fascinating life processes of these creatures are described with affectionate care. The animals are grouped according to their most characteristic habitat, whether rocky shore, sandy beach, mud flat, or wharf piling, and the authors discuss their life history, physiology, and community relations, and the influence of wave shock and shifting tide level. Though the basic purpose and structure--and much of the text--of the book remain the same, content has been increased by about 20 percent; a multitude of changes and additios has been made in the text; the Annotated Systematic Index and General Bibliography have been updated and greatly expanded (now almost 2,300 entries); more than 200 new photographs and drawings have been incorporated; and an entirely new chapter has been added--a topical presentation of the several factors influencing distribution of organisms along the shore. This edition also includes John Steinbeck's Foreword to the 1948 edition.

Download or read book Ecology written by W. D. Russell-Hunter and published by Elsevier. This book was released on 2013-09-24 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mollusca, Volume 6: Ecology provides an overview of the state of knowledge in molluscan ecology. It is part of a multivolume treatise that covers the fields of biochemistry, physiology, neurobiology, reproduction and development, evolution, ecology, medical aspects, and structure. The Mollusca is intended to serve a range of disciplines: biological, biochemical, paleontological, and medical. As a source of information on the current status of molluscan research, it should prove useful to researchers of the Mollusca and other phyla, as well as to teachers and qualified graduate students. The book contains 15 chapters, arranged into three levels of ecological perspective: (a) distributional studies; (b) physiological ecology and bioenergetics; and (c) population genetics and dynamics. A discussion of the planetary distribution of and ecological constraints upon the mollusca is followed by separate chapters on the life styles and distribution of mollusks on the deep-sea bottom, in mangroves, and on coral reefs; and the trophic and reproductive ecology of those intrinsically fascinating molluscan groups—the nudibranchs and cephalopods. Subsequent chapters present physiological ecology in land snails and in freshwater bivalves, prosobranchs, and pulmonates, with a survey of the techniques of actuarial bioenergetics as applied to nonmarine molluscs. Other chapters cover population dynamics and biology in an introduced pest species, population genetics of marine molluscs, ecogenetics of land snails, and life-cycle pattems throughout the major molluscan taxa.
