This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex determination, differentiation and gamete maturation are well organised molecular events in vertebrates. In vertebrates, sex determination and differentiation are two important events in the development of gonads (testis or ovary). Sex determination is the genetic (sex chromosomes) or environmental process by which the sex (male or female) of an individual is established. During embryonic development, primordial germ cells migrate from the site of origin to the gonadal primordia where they differentiate along with somatic cells and finally form the indifferent/bipotential gonads. Depending on the action of various factors the bipotential gonads give rise to either testis or ovaries. In most vertebrates, excluding fishes and some amphibians, the event of sex determination is controlled genetically and later the progression of gonadal development is controlled by hormones and other factors. Interestingly, these processes in fishes are controlled not only genetically but also through hormones or environmental factors. These characteristics make fish the champions of sex reversal and serve as excellent animal models to precisely understand sexual development. The next interesting aspect is meiotic maturation which is essentially mediated by gonadotropins and progesterone metabolites to trigger final gamete maturation in fishes which is different from mammals. The novel aspects pertaining to gamete maturation has been studied in great detail in fish which depicts precise regulatory events of gamete maturation.
Book Synopsis Endocrine Sex Differentiation in Fish by : T. J. Pandian
Download or read book Endocrine Sex Differentiation in Fish written by T. J. Pandian and published by CRC Press. This book was released on 2013-05-07 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all vertebrates, fish exhibit unparalleled diversity of sexual plasticity and flexibility, ranging from gonochorism to unisexualism, and exceptional patterns of functional hermaphroditism. Fish farming and monosex aquaculture have led to reproductive dysfunction with males producing less milt, and females failing to ovulate and spawn. This book brings together relevant information on the role of the endocrine system on sexual differentiation in fish, and bridges the gap between molecular endocrinologists and fishery scientists.

Download or read book Atlantic Cod written by George A. Rose and published by John Wiley & Sons. This book was released on 2019-02-26 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive handbook, covering all aspects of the Atlantic cod including the biology, ecology, life histories, behaviour, commercial exploitation and conservation Not only is Atlantic cod one of the most valuable food fish in the world’s oceans, it is an important component of North Atlantic ecosystems and has been subject to much research into its biology, ecology and exploitation. After hundreds of years of exploitation, overfishing in the last half of the 20th Century caused many stocks to collapse, most famously the Northern cod stock off Newfoundland and Labrador, Canada. Since then, most cod stocks have been better researched and managed, but remain in a variety of states, from fully recovered to continued decline. This book, written by world experts, describes that research and management, and the importance of cod and its fisheries on North Atlantic cultures and economies, with impacts well beyond the range of the species. Atlantic Cod: Bio-Ecology of the Fish offers insightful chapter coverage of cod nomenclature, taxonomy, phylogeny and morphology; physiology and ecophysiology; reproduction and spawning behavior; early life history and pre-recruitment processes; migrations, movements and stock identity; feeding, growth and energetics; the place of cod in the ecosystem; the exploitation of cod through history and present day commercial fisheries and precautionary management for sustainable fisheries; impacts of climate change on cod biology and ecology; and the future of the species and its fisheries. Discusses the major commercial importance of Atlantic cod through history Provides a comprehensive treatment of the bio-ecology of the most researched and highly exploited fully marine species Examines how the decline (and recovery) of cod stocks is of great political and scientific interest An essential purchase for marine fisheries scientists Atlantic Cod: Bio-Ecology of the Fish is a vital book for all fisheries scientists, managers and fish biologists.

Book Synopsis Reproductive and Developmental Strategies by : Kazuya Kobayashi
Download or read book Reproductive and Developmental Strategies written by Kazuya Kobayashi and published by Springer. This book was released on 2018-06-01 with total page 783 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides new insights into the universality of biological systems in animal reproduction and development by a comparative study of a variety of mechanisms in animals ranging from basal invertebrates to vertebrates, including mammals. Animals accomplish genetic diversity through meiosis and fertilization, and during embryogenesis animals must produce specialized cell types, including germ cells, in accordance with their individual body plan. This series of phenomena is essential to the continuity of life in the animal kingdom, and animals show various reproductive and developmental strategies. This volume, comprising four parts, reviews animal kingdom diversity, including reproductive strategies and germ cell differentiation mechanisms (Part 1), sex determination and differentiation (Part2), the mechanisms of fertilization (Part 3), and body axis formation (Part 4). Readers will find descriptions of the reproduction or development of 180 species, 13 phyla, 35 classes, 74 orders, 117 families, and 151 genera in this book. Of particular interest is the diversity of molecules and mechanisms used to achieve the same biological purpose in different animals. Undergraduates, graduate students, and professional scientists who want a deeper understanding of animal reproductive and developmental mechanisms will find this book to be of great value.

Book Synopsis Sexual Reproduction in Animals and Plants by : Hitoshi Sawada
Download or read book Sexual Reproduction in Animals and Plants written by Hitoshi Sawada and published by Springer. This book was released on 2014-02-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.
Download or read book Global Warming written by C. M. Wood and published by Cambridge University Press. This book was released on 1997-05-13 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming and climate change are growing environmental concerns which are much in the scientific, governmental and public eye. The potential impact on freshwater and marine fishes is immense, because most fish have no physiological ability to regulate their body temperature. This volume focuses on the effects of temperature at all levels of organization in fish, with particular emphasis on physiological function: cells, epithelia, organ systems, the whole organism, reproduction, behaviour, pollutant interactions, ecology and population dynamics, with each chapter written by experts in the field. Many chapters also speculate on the long-term physiological and ecological implications to fish of a 2-4°C global warming scenario. Researchers and graduate students in the areas of animal physiology and behaviour, environmental toxicology, population ecology and fisheries biology and management will find this volume of particular interest.
