Download or read book Sex Control in Aquaculture written by Hanping Wang and published by John Wiley & Sons. This book was released on 2018-11-08 with total page 1810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Download or read book The Olfactory System written by Kensaku Mori and published by Springer. This book was released on 2014-05-07 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes recent advances in understanding of the mammalian and fish olfactory system and provides perspective on the translation of external odor information into appropriate motivational and behavioral responses. Following the discovery of the odorant receptor gene family in 1991, understanding of the basic biological mechanisms of the olfactory system has advanced enormously. Despite such rapid progress, however, it remains unclear how odor information is processed at levels beyond the olfactory bulb, including the olfactory cortex, olfactory tubercle, and orbitofrontal cortex. This book thus describes the most recent developments in olfactory research, with particular focus on the basic neurobiological mechanisms of the neuronal circuit function in the olfactory system and its related higher centers. Exploring the basic functional logic of the neuronal circuits in the olfactory system in this way appears to be crucial in understanding the workings of the complex neuronal circuits of the brain, particularly those in the cerebral cortex that link sensory perception to appropriate behavioral responses. This book is written for the coming generation of scientists: undergraduates, graduate students, and postdoctoral researchers in the fields of neuroscience, neurobiology, chemical senses, food and nutritional sciences, medical science, sensory psychology, and behavioral sciences.
Download or read book Kallmann Syndrome and Hypogonadotropic Hypogonadism written by R. Quinton and published by Karger Medical and Scientific Publishers. This book was released on 2010-04-12 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, the understanding of the processes involved in the regulation of gonadotropin-releasing hormone and its dysfunction has greatly increased. As new regulatory peptides have been identified, the underlying causes of central hypogonadism have multiplied, and the area has become increasingly complex. The reversibility of even genetically determined hypogonadotropic hypogonadism has become more firmly established, and clinical studies have greatly expanded our understanding of basic physiological pathways. Structuring this mass of new knowledge in thirteen comprehensive chapters, a group of renowned experts, representing the principal international research groups, take stock of the most recent progress.This up-to-date overview helps scientists and clinicians to plan future research and treat patients with delayed puberty, hypogonadotropic hypogonadism and other forms of central reproductive disorders.

Book excerpt: This book combines the most recent knowledge on the maternal, i.e. oocyte/egg-specific, molecules and processes. The volume covers the most recent advances in a plethora of subjects such as: maternal transfer of immunity, localized RNAs functions and mechanisms of RNA localization, transcriptional repression of maternal messages, maternal inheritance and maternal role of CRISPR/Cas9-based genome editing, chromatin remodeling and epigenetic modifications, maternal function of nucleosomes, maternal mitochondria and energy supply, role of bacterial symbionts and their maternal transmission, acquisition of oocyte polarity and evolution of maternal effect genes, germ plasm and oosome origin and functions, mechanisms of oocyte activation and soma germ cells communication. Currently, no other book on the market combines such a comprehensive list of subjects in one volume. Moreover, the information provided is a cross-section through oocytes from various invertebrate and vertebrate species, which is another unique feature of this book. The readers, therefore, get a completely new and invaluable perspective on all covered subjects.
Download or read book Plant Microtechniques and Protocols written by Edward Chee Tak Yeung and published by Springer. This book was released on 2015-09-19 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: A proper understanding of the structural organization of the plant body is essential to any study in plant biology. Experimental studies in vivo and in situ will lead to structural, physiological, and cellular changes of the experimental material. To study macroscopic and microscopic changes, different histological methods and microtechniques can be used as they provide valuable information of the experimental system. In addition, the observed structural changes allow investigators to set hypothesis for further studies based on one’s own observation. Thus, proper selection and utilization of microtechniques are a must for the success of a research program. At present, an up-to-date collection of protocols are not readily available in the literature. The latest work in plant microtechniques was published in 1999 by Ruzin but many others are no longer in print [e.g., Jensen (1964); O’Brien and McCully (1981)]. Furthermore, a majority of published works focus on techniques related to general processing and staining procedures. A comprehensive treatment that encompasses broader applications of microtechniques to other disciplines is lacking [e.g., archeology, wood science, etc.]. There is a need to create a comprehensive volume of botanical methods and protocols which includes traditional and novel techniques that can be used by researchers in plant science and investigators in other disciplines that require plant microtechniques in their research and teaching. This book covers a wide variety of applications and brings them up-to-date to make them understandable and relevant, especially to students using the methods for the first time. It is our intention to create a useful reference for plant histology and related methods that will serve as a foundation for plant scholars, researchers, and teachers in the plant sciences.

Download or read book Neuropeptide GPCRs in neuroendocrinology written by Jae Young Seong and published by Frontiers E-books. This book was released on 2014-11-07 with total page 826 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human genome encompasses ˜ 860 G protein-coupled receptors (GPCRs) including 374 non-chemosensory GPCRs. Half of these latter GPCRs recognize (neuro)peptides as natural ligands. GPCRs thus play a pivotal role in neuroendocrine communication. In particular, GPCRs are involved in the neuroendocrine control of feeding behavior, reproduction, growth, hydromineral homeostasis and stress response. GPCRs are also major drug targets and hence possess a strong potential for the development of innovative pharmaceuticals. The aim of this Research Topic was to assemble a series of review articles and original research papers on neuropeptide GPCRs and their ligands that would illustrate the different facets of the studies currently conducted in this domain.
