Download or read book Reproduction and Development of Marine Invertebrates of the Northern Pacific Coast written by Megumi F. Strathmann and published by University of Washington Press. This book was released on 2017-10-01 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.
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.

This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on prec'entations at the conference on Culture of Marine Invertebrate Animals which was held in Green port, New York in October, 1972. The conference was sponsored by the Middle Atlantic Natural Sciences Council, Inc., a non profit educational corporation, together with the Marine Science Centers of Adelphi University, the State University of New York at Stony Brook, Long Island University, Suffolk County Community College, and the Shelter Island Oyster Company. The purpose of the conference was to provide a needed ex change of knowledge among scientists of various specialties whose information would be invaluable to others confronted with similar problems, even with different marine animals. Part I considers supportive techniques -- general isolation and culture methods, problems of disease and feeding. Specific techniques employed in the culture of a wide range of invertebrate organisms is covered in Part II. We want to thank the contributors for their cooperation in preparing the manuscripts based on their conference presentations. Walter L. Smith Matoira H.

Download or read book Bioactive Compounds from Natural Sources written by Corrado Tringali and published by CRC Press. This book was released on 2003-09-02 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in obtaining biologically active compounds from natural sources has recently spiked due to their low toxicity, complete biodegradability, availability from renewable sources, and in most cases, low cost. Taking an interdisciplinary approach, Bioactive Compounds from Natural Sources: Isolation, Characterization, and Biological Properties covers general methods and main topics in the research field of bioactive natural products. The book describes general screening methods, modern HPLC hyphenated techniques, and NMR methods in the structural elucidation of compounds and devotes individual chapters to specific topics of research. Surveys on compounds displaying important pharmacological activities are presented in chapters devoted to Mexican medicinal plants, anti-tumor drugs of natural origin, cancer chemopreventive flavonoids, and metabolites displaying anti-HIV, antioxidative, antimalarial, and anti-inflammatory activity. The final chapters are devoted to representative examples of research into marine metabolites: immunomodulating marine glycolipids and surveys of bioactive compounds from marine opisthobranchs and Japanese soft corals. With its focus on modern approaches to the isolation of biologically active natural products, this book encourages interdisciplinary work among chemists, pharmacologists, biologists, botanists, and agronomists with an interest in bioactive natural products.

Download or read book Sea Snails written by Joseph Heller and published by Springer. This book was released on 2015-06-16 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated book presents the diversity and natural history of sea snail groups. By integrating aspects of morphology, ecology, evolution and behaviour, it describes how each group copes with problems of defence, locomotion, nutrition, reproduction and embryonic development. First come general characteristics of the Mollusca, to which snails belong; and next, characteristics by which snails (Gastropoda) differ from other molluscs. Then a broad, panoramic view of all major sea snail groups, from the primitive to the more advanced, is presented, including both the more abundant and some remote ones of special interest. In detailing primitive sea snails, first limpets (Patellogastropoda) are described, followed by brush snails (Vetigastropoda: top-shells, turbans and allies) and nerites (Neritimorpha), a small group with remarkably high variation in shell colour and in habitats. In looking at advanced-snails (Caenogastropoda), it details the herbivorous grazers and filter-feeders and the many voracious predators, some which use venomous darts. The book also covers sea slugs (Opisthobranchia), which have shifted from mechanical to chemical defence; some are herbivores, some use their food to harness solar energy, others are predators that gain stinging cells and poisonous compounds from their food. In addition, readers will learn about aspects of sea snails in human culture, including use as sacred artefacts and objects of magic and money, as a source of the royal and sacred dyes of purple and blue and as holy ceremonial trumpets. The text, in which scientific terms are accompanied by parallel common ones, is accompanied by over 200 illustrations (mostly in colour). This comprehensive, insightful portrait of sea snails will appeal to marine biologists, zoology lecturers and students, biology teachers, field-school instructors, nature reserve wardens, amateur naturalists, as well as to lecturers and learners of human culture.
Download or read book General Parasitology written by Thomas C. Cheng and published by Elsevier. This book was released on 2012-12-02 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Preface:Over a dozen years have passed since the first edition of this textbook was published. As is to be expected, tremendous progress has been made in the study of zooparasites and the nature of parasitism. This is especially true in the case of the protozoans and helminths of medical and economic importance. Continuing the original intent, this book is meant to be a teaching tool rather than a reference volume for seasoned investigators. It is meant to supplement formal lectures, but at the same time to provide students with sufficient information as to where more detailed review articles and primary research reports can be located.
