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 508 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 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.

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.

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.

This book was released on 2005-07-13 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annelida, mainly consisting of marine Polychaeta and in faunal and partly parasitic Clitellata, is one the most significant metazoan taxa. Its more than 20.000 described species invade nearly all habitats and play a central role in marine benthic systems as well as in terrestrial soil communities. Annelids include all soft-bodied segmented worm-like organisms and have been recognized as a separate "phylum" for almost 200 years. Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.

Available in PDF, EPUB and Kindle. Book excerpt: At one time or another, we have all been drawn by the fascination of the seashore. For the holiday maker, the relaxing day by the sea often turns out to be a most rewarding foray among rock pools and dense canopies of seaweed; for naturalists and students, the shore is one of the most challenging habitats. Whatever our interests and expertise, one of our first objectives when faced with the diversity of plant and animal life on the shore is to name the individual specimens and we quickly learn that this can be a difficult, though rewarding, occupation. Once an organism has been identified, a number of questions naturally follow. What is its life-cycle? How does it feed and reproduce? How long does it live? The answers to such questions give an insight into the lives of the plants and animals of the shore and are one of the first steps in an understand ing of the complexity of the shore environment. However, the information required to answer such questions is not always easily accessible and even when it is known it is often scattered in various books and research journals making it difficult and time consuming to find. Although a variety of identification keys and guides is available, some designed for the specialist, others for the amateur, such texts generally give little, if any, information on the biology of the organisms.
