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 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.

Download or read book Reproduction written by A. S. Tompa and published by Elsevier. This book was released on 2013-10-22 with total page 507 pages. Available in PDF, EPUB and Kindle. 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 Evolution written by E. R. Trueman and published by Academic Press. This book was released on 2013-10-22 with total page 512 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Edition of The Light and Smith Manual continues a sixty-five-year tradition of providing to both students and professionals an indispensable, comprehensive, and authoritative guide to Pacific coast marine invertebrates of coastal waters, rocky shores, sandy beaches, tidal mud flats, salt marshes, and floats and docks. This classic and unparalleled reference has been newly expanded to include all common and many rare species from Point Conception, California, to the Columbia River, one of the most studied areas in the world for marine invertebrates. In addition, although focused on the central and northern California and Oregon coasts, this encyclopedic source is useful for anyone working in North American coastal ecosystems, from Alaska to Mexico. More than one hundred scholars have provided new keys, illustrations, and annotated species lists for over 3,500 species of intertidal and many shallow water marine organisms ranging from protozoans to sea squirts. This expanded volume covers sponges, sea anemones, hydroids, jellyfish, flatworms, polychaetes, amphipods, crabs, insects, snails, clams, chitons, and scores of other important groups. The Fourth Edition also features introductory chapters on marine habitats and biogeography, interstitial marine life, and intertidal parasites, as well as expanded treatments of common planktonic organisms likely to be encountered in near-to-shore shallow waters.
