This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic sea urchin, Sterechinus neumayeri, develops more slowly than its warm water counterparts, although the pattern of early development is the same as in other sea urchin species. There is available data on the effects of temperature on S. neumayeri embryos, however information about impacts of salinity on their development is not well documented. In this study, two and four parts per thousand decreases in standard salinity were tested to see if the developmental rate of S. neumayeri embryos would be further slowed by hyposmotic stress. During the austral summer of 2005, adult urchins were collected from McMurdo Sound and spawned at McMurdo Station, Antarctica. Immediately after fertilization, individual zygotes were placed in three separate salinity treatments within the wells of a 96-well microtiter plate modified to maintain constant temperatures. The salinity treatments were 34 (n=265), 32 (n=89) and 30 [per thousand] (n=198). Early cleavage stages were observed up until the formation of a morula, approximately 35-38 hours post fertilization (h PF) on average for S. neumayeri at -1.86 °C. For standard development (96 % viable zygotes), 47% of these embryos passed the morula stage within 36 h PF at 34 [per thousand], whereas 4.6% of the embryos in 30 [per thousand] developed to morula by 36 h PF. No embryos in 32 [per thousand] developed to morula stage by this time. This is the first study to investigate the responses of S. neumayeri embryos to a decrease in salinity. Antarctic sea urchins have the ability to alter marine ecosystem structure due to their grazing and movements about the sediment, and if S. neumayeri experiences lowered recruitment numbers due to the influx of freshwater from the melting of ice shelves attributed to climate warming, the benthic environment of Antarctica could be substantially impacted.

This book was released on 2013-08-13 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesizing decades of work, but up-to-date, this book focuses on organism-level responses to pollutants by marine animals, mainly crustaceans, molluscs, and fishes. Emphasizing effects on physiological processes (feeding/digestion, respiration, osmoregulation), life-cycle (reproduction [including endocrine disruption], embryo development, larval development, developmental processes later in life (growth, regeneration, molting, calcification, cancer), and behaviour, the book also covers bioaccumulation and detoxification of contaminants, and the development of tolerance. The major pollutants covered are metals, organic compounds (oil, pesticides, industrial chemicals), nutrients and hypoxia, contaminants of emerging concern, and ocean acidification. Some attention is also devoted to marine debris and noise pollution.​

Download or read book Reproduction and Development of Marine Invertebrates written by W. Herbert Wilson (Jr.) and published by . This book was released on 1994 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Reproduction and Development of Marine Invertebrates a group of internationally recognized researchers assesses the state of current knowledge in the field and identifies future avenues of research. Comprehensive in scope, the book treats all levels of biological organization, from the molecular level to communities of organisms. After a brief historical overview that identifies the conceptual underpinnings of twentieth-century invertebrate zoology and embryology, the book is organized by developmental stages. The authors first present chapters on oogenesis, spermatogenesis, fertilization, and embryonic development. A subsequent section--arranged phylogenetically to encompass annelids, priapulans, molluscs, bryozoans, and echinoderms--covers larval morphology and evolution. The final section treats larval or adult populations and includes new information on the role of hydrodynamics to aid in the understanding of larval dispersal and settlement. Reproduction and Development of Marine Invertebrates is the first book of its kind to be published since 1978. Extensivelyillustrated with more than a hundred line drawings and photos--including sixty high-resolution electron micrographs--it will be of interest to professionals and students in evolutionary biology, invertebrate zoology, developmental biology, and functional morphology.

Download or read book Advances in Comparative Immunology written by Edwin L. Cooper and published by Springer. This book was released on 2018-08-07 with total page 1048 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunologists, perhaps understandably, most often concentrate on the human immune system, an anthropocentric focus that has resulted in a dearth of information about the immune function of all other species within the animal kingdom. However, knowledge of animal immune function could help not only to better understand human immunology, but perhaps more importantly, it could help to treat and avoid the blights that affect animals, which consequently affect humans. Take for example the mass death of honeybees in recent years – their demise, resulting in much less pollination, poses a serious threat to numerous crops, and thus the food supply. There is a similar disappearance of frogs internationally, signaling ecological problems, among them fungal infections. This book aims to fill this void by describing and discussing what is known about non-human immunology. It covers various major animal phyla, its chapters organized in a progression from the simplest unicellular organisms to the most complex vertebrates, mammals. Chapters are written by experts, covering the latest findings and new research being conducted about each phylum. Edwin L. Cooper is a Distinguished Professor in the Laboratory of Comparative Immunology, Department of Neurobiology at UCLA’s David Geffen School of Medicine.

Download or read book Reproduction and Development of Marine Invertebrates of the Northern Pacific Coast written by Megumi F. Strathmann and published by Seattle : University of Washington Press. This book was released on 1987 with total page 670 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.

The ever increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative reviews summarizing the results of recent research. OMBAR has catered to this demand since its foundation more than 50 years ago. Following the favourable reception and complimentary reviews accorded to all the volumes, Volume 56 continues to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields, and every chapter is peer-reviewed by other experts working actively in the specific areas of interest. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments.
