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 Nutritional approaches to arresting the decline in fertility of pigs and poultry written by J.A. Taylor-Pickard and published by BRILL. This book was released on 2023-08-28 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Continued genetic development of pigs and poultry has been the foundation of profitable production within a competitive market. However, the challenges of these production increases have undoubtedly taken their toll on reproductive function in all breeding livestock, with the incidence of infertility increasing at an alarming rate. For example, it has recently been estimated that over 40% of sows are culled due to fertility problems, compared to just 12% with feet and leg issues. This edited collection of papers is taken from a series of seminars, devoted to bringing together some of the world’s leading authorities in the field of pig and poultry reproduction. The fundamental aim being to re-examine the current trends in productivity in the pig and poultry industries, and to identify nutritional means to improve fertility. It considers the effects of essential nutrients in optimising productivity, and discusses innovative applications of nutrition that will help to enhance fertility. The success of such innovations within entrepreneurial integrated systems is also covered, together with the importance of producing a quality chick and piglet at birth/hatching. Finally, the role of management and the need for least cost production is discussed. Nutritional Approaches to Arresting the decline in Fertility of Pigs and Poultry is aimed at nutritionists and animal producers as well as students and researchers studying animal and applied biological sciences."
Download or read book Current and Future Reproductive Technologies and World Food Production written by G. Cliff Lamb and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species.

Download or read book The Evolution of Primary Sexual Characters in Animals written by Janet Leonard and published by Oxford University Press. This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Download or read book Male Fertility and Lipid Metabolism written by Stephanie R. De Vriese and published by The American Oil Chemists Society. This book was released on 2003-05-30 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in lipid metabolism and polyunsaturated fatty acids in relation to sperm production has increased during the last decade. The motivation for the research described in this book originates from the discovery that sperm lipids contain extremely high proportions of long-chain polyunsaturated fatty acids, thus establishing a link between lipid biochemistry and male fertility. Moreover, the fact that polyunsaturated fatty acids must, in some form, be supplied in the diet suggests a relationship between fertility and nutrition and raises the possibility of improving male fertility by dietary means. This book gives the reader an up-to-date view of several aspects of male fertility in relation to lipid and fatty acid metabolism. Researchers in the domain of male fertility, fatty acid metabolism, and antioxidants; medical personnel involved in the treatment of male infertility; fat technologists; students in nutrition, dietetics, biochemistry, pharmacy, and medicine; and everybody interested in the field will find this book useful.
