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 Reproductive Strategies and Developmental Patterns in Annelids written by Adriaan W.C. Dorresteijn and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascination of the Annelida to scientists lies in the beauty of their structures and the functionality of their body plan, the tremendous adaptive radiation which has made it possible for these animals to colonize almost all marine, limnic and terrestrial biotopes. In doing so they have evolved a great variety of life forms, and their reproduction and development are correspondingly diverse, with many modes and patterns unique in the animal kingdom. In this special volume recent progress in this broad research area is presented by 26 specialists, in general through surveys or treatments of selected examples. Some of them review important annelid taxa such as the Nereididae, Syllidae, Spionidae, Cirratulidae, Clitellata, and Pogonophora; others analyse reproductive and developmental structures and phenomena in annelids, e.g. segmental organs, sex pheromones, oogenesis, mating systems, sperm types, life cycles, larval settlement, cleavage and symmetry of embryos, or discuss controversial approaches to annelid systematics. The book will be of interest to all zoologists who work with annelids as well as to embryologists and other researchers in reproductive biology.
Download or read book Reproduction and Development in Annelida written by T. J. Pandian and published by CRC Press. This book was released on 2019-01-30 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a concise informative elucidation of all aspects of reproduction and development in annelids covering from arenicola to tubifex. Annelids flourish between 4,900 m depth to 2,000 m altitude; some of them occur in unusual habitats like hydrothermal vents and subterranean aquatic system (stigobionts). A few have no gut and acquire adequate nutrients through osmotrophism and/or engaging symbiotic microbes. In the absence of exoskeleton to escape predation, the 17,000 speciose annelids have explored bewildering modes of reproduction; not surprisingly, 42–47% of them are brooders. With 13,000 species, polychaetes are gonochores but some 207 species of them are hermaphrodites. Clitellates are all hermaphrodites; of them, 76 species are parthenogens, of which 56 are earthworms. Regenerative potency of annelids ranges from an organ to an entire worm from a single ‘seminal’ segment. The head, tail and both together can be regenerated 21, 42 and 20 times, respectively. However, the potency is limited to ~1% of polychaetes and Heterogamatic sex determination is reported to occur only in six polychaete species, although karyotype is known for 83 annelid species. In temperate polychaetes, a dozen neuroendocrines, arising mostly from the ‘brain’ regulates reproductive cycle. A complete chapter devoted to vermiculture, (i) recognizes the fast-growing candidate species, (ii) distinguishes 'layers' from 'brooders', (iii) indicates that the harvest of oligochaetes may reduce the input of nitrogenous fertilizer in the ricefield, and (iv) explores the scope for increasing wealth from waste.
Download or read book Reproduction of Marine Invertebrates V3 written by Arthur Giese and published by Elsevier. This book was released on 2012-12-02 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Marine Invertebrates, Volume III: Annelids and Echiurans illustrates the importance of annelids and echiurans in the evolution of reproductive mechanisms and in the ecology of the sea. It discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of specific annelids, such as polychaeta and clitellata, and of echiurans. The annelids appear to be midway forms in the evolutionary progression of the metazoans. The echiurans, with close affinities to the annelids, are organisms that have become increasingly important for researches in developmental biology. The book will be helpful to marine scientists and biologists, reproduction researchers, and developmental biologists.
Download or read book Marine Ornamental Species Aquaculture written by Ricardo Calado and published by John Wiley & Sons. This book was released on 2017-02-15 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global trade of aquatic organisms for home and public aquariums, along with associated equipment and accessories, has become a multi-billion dollar industry. Aquaculture of marine ornamental species, still in its infancy, is recognized as a viable alternative to wild collection as it can supplement or replace the supply of wild caught specimens and potentially help recover natural populations through restocking. This book collects into a single work the most up-to-date information currently available on the aquaculture of marine ornamental species. It includes the contributions of more than 50 leading scientists and experts on different topics relevant for the aquaculture of the most emblematic groups of organisms traded for reef aquariums. From clownfish, to angelfish, tangs and seahorses, as well as corals, anemones, shrimps, giant clams and several other reef organisms, all issues related with the husbandry, breeding, and trade are addressed, with explanatory schemes and illustrations being used to help in understanding the most complex topics addressed. Marine Ornamental Species Aquaculture is a key reference for scientists and academics in research institutes and universities, public and private aquaria, as well as for hobbyists. Entrepreneurs will also find this book an important resource, as the culture of marine ornamental species is analyzed from a business oriented perspective, highlighting the risks and opportunities of commercial scale aquaculture of marine ornamentals.

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.
