Reproductive and Developmental Strategies: The Continuity of Life (Diversity and Commonality in Animals)
by Kazuya Kobayashi Takeshi Kitano Yasuhiro Iwao Mariko KondoThis 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.

Reproductive Biology and Phylogeny of Fishes, Vol 8B: Part B: Sperm Competion Hormones
by Barrie G. M. JamiesonThe animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the subject of volume 3 in this series. It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproductive system and its components, is the subject of Part A. Part B deals with complementary topics: testes, sperm, and sperm competition; endocrinology of reproduction; pheromones and reproduction; copulatory structures: taxonomic overview and the potential for sexual selection; sexual selection: signaling and courtship; adaptation and evolution of reproductive mode in copulating cottoid species; fertilization; sex determination; parental care; reproduction in relation to conservation and exploitation of marine fishes; Cryopreservation of Gametes; Embryogenesis and Development; and Molecular Genetics of Development.

Reproductive Diversity of Plants
by Marines Marli Gniech KarasawaThe first part of the book presents the evolution of plants starting from photosynthetic cells to topics like Gymnosperms and Angiosperms, including the evolution of the breeding system. Geological and molecular data were used, helping us to show with more details each of the phases presented. Also, specialization of the reproductive systems such as evolution of unissexuality (dioecy and monoecy), evolution of self-incompatibility, selfing fertilization and mixed mating systems were considered. The last part discusses the biology and genetics of the reproductive systems and shows the strategies that modern plants use in asexual reproduction (vegetative and apomictic reproduction) and sexual reproduction. In addition, the sexual reproduction topics such as gametogenesis, the genetic control of reproductive organs, systems that promote outcrossing, selfing and mixed mating systems were also included.
Reproductive Ecology of Flowering Plants: A Manual
by K. R. Shivanna Rajesh TandonSuccessful reproduction is the basis not only for the stability of the species in their natural habitat but also for productivity of our crop plants. Therefore, knowledge on reproductive ecology of wild and cultivated plants is important for effective management of our dwindling biodiversity and for the sustainability and improvement of the yield in crop species. Conservation and management of our plant diversity is going to be a major challenge in the coming decades, particularly in the tropical countries which are rich in biodiversity. Reproductive failure is the main driver for pushing a large number of tropical species to vulnerable category. Available data on reproductive ecology on tropical species is very limited and there is an urgent need to initiate research on these lines. A major limitation for the beginners to take up research is the absence of simple concise work manuals that provide step-wise procedures to study all aspects of reproductive ecology. The Manual fills this void. Over 60 protocols described in the manual cover the whole spectrum of reproductive ecology - study sites and species, phenology, floral morphology and sexuality, pollen and pistil biology, pollination ecology, breeding system, seed biology, seed dispersal and seedling recruitment. Each chapter gives a concise conceptual account of the topic before describing the protocols. The Manual caters to researchers, teachers and students who are interested in any aspect of reproductive ecology of flowering plants -- botanists, ecologists, agri-horticulturists, foresters, entomologists, plant breeders and conservation biologists.
Reproductive Ecology of Flowering Plants: Patterns and Processes
by Rajesh Tandon K. R. Shivanna Monika KoulSexual reproduction is the predominant mode of perpetuation for flowering plant species. Investigating the reproductive strategies of plants has grown to become a vast area of research and, in crop plants, covers events from flowering to fruit and seed development; in wild species, it extends up to seed dispersal and seedling recruitment. Thus, reproduction determines the extent of yield in crop plants and, in wild plants, also determines the efficacy of recruiting new adults to the population, making this field important both from fundamental and applied plant biology perspectives. Moreover, in light of the growing concerns regarding food and nutritional security for the growing population and preserving biological diversity, reproductive biology of flowering plants has acquired special significance. Extensive studies on various facets of reproduction are being carried out around the world. However, these studies are scattered across research journals and reviews from diverse areas of biology.The present volume covers the whole spectrum of reproductive ecology, from phenology and floral biology, to sexuality and pollination biology/ecology including floral rewards, breeding systems, apomixis and seed dispersal. In turn, transgene flow, its biosafety and mitigation approaches, and the ‘global pollinator crisis’, which has become a major international concern in light of the urgent need to sustain crop yield and biodiversity, are discussed in detail. Given its scope, the book offers a valuable resource for students, teachers and researchers of botany, zoology, ecology, agriculture and forestry, as well as conservation biologists.
Reproductive Endocrinology
by P. Jorge ChedreseMolecular biology emerged from advances in biochemistry during the 1940s and 1950s, when the structure of the nucleic acids and proteins were elucidated. Beginning in the 1970s, with nucleic acid enzymology and the discovery of the restriction enzymes, the tools of molecular biology became widely available and applied in cell biology to study how genes are regulated. This new knowledge impacted endocrinology and reproductive biology since it was largely known that the secretion of the internal glands affected the phenotypes, and expression of genes. Modern reproductive biology encompasses every level of biological study from genomics to ecology, encompassing cell biology, biochemistry, endocrinology and general physiology. All of these disciplines require a basic knowledge, both as a tool and as an essential aid to a fundamental understanding of the principles of life in health and disease. Overall, molecular biology is central to scientific studies in all living matter, impacting disciplines such as medicine, related health sciences, veterinary, agriculture and environmental sciences. In this book, the basic biochemistry of nucleic acids and proteins are reviewed. Methodologies used to study signaling and gene regulation in the endocrine/reproductive system are also discussed. Topics include mechanisms of hormone action and several endocrine disorders affecting the reproductive system. Professionals in the medical, veterinary and animal sciences fields will find exciting and stimulating material enhancing the breadth and quality of their research.
Reproductive Endocrinology and Infertility
by Dr. Vivian LewisReproductive Endocrinology and Infertility provides an overview of the most frequently encountered clinical challenges faced by medical students and residents. Part I begins with chapters on reproductive hormonal physiology and development to provide a basis for understanding the management of the most common reproductive clinical problems that confront obstetrician-gynecologists and other practitioners in women’s health. Several of the chapters, including obesity, premenstrual syndrome, menopause and imaging, provide a cross-disciplinary approach to endocrine related problems common among reproductive aged women. Part II includes chapters on the evaluation of infertility, as well as surgical and medical approaches to treating infertility in men and women. The chapter on alternative medicine provides a basis for understanding the increasingly popular use of therapies such as acupuncture and herbal treatments. The last chapter discusses the influence of environmental factors on fertility, an important field that is often ignored in the traditional approach to infertility.This text is meant to be used as a portable reference with readily accessible information including a summary of key points in each chapter. All of the contributors are involved in residency training programs and understand the kinds of patient management questions that are encountered in a busy practice. Our goal with this book is to provide information that will support solid patient management and hopefully pique the appetite to learn more.
Reproductive Endocrinology for the MRCOG and Beyond
by Adam Balen Jenny HighamUnderstanding endocrinology is central to understanding the key processes that affect normal reproductive function, while an understanding of normal endocrinology and the pathophysiology of endocrine disorders is important when dealing with reproductive disorders. This book provides a comprehensive background for all gynaecologists, covering: sexual differentiation and intersex disorders; adrenal disorders; normal puberty and adolescence; abnormal puberty; the menstrual cycle; disorders of menstruation; amenorrhoea; polycystic ovary syndrome; anovulatory fertility and ovulation induction; lactation and lactational amenorrhoea; hyperprolactinaemia; thyroid disease; diabetes; lipid metabolism and lipoprotein transport; premature ovarian failure; and calcium metabolism and its disorders. The book is primarily designed to provide a comprehensive summary for candidates preparing for the Part 2 MRCOG examination, and as such covers the RCOG curriculum for reproductive endocrinology. It is also a valuable guide for all healthcare professionals working in the field, including trainees, consultants and any health professional coming into contact with women.
Reproductive Genetics
by Sean Kehoe Lyn Chitty Tessa HomfrayThis is a unique book, covering areas not available elsewhere. Within its pages, the authors discuss many diverse areas relating to reproduction and genetics. Great progress has been made in the field of genetics within the past decade. This, combined with our growing knowledge, has impacted on this important area with interesting consequences. The ability to identify genetic defects before implantation, to diagnose fetal abnormalities and to introduce screening programmes means that genetic testing now has a major role in preventive medicine. These topics are discussed in detail in the book. In parallel with these advances, other aspects that cannot be ignored, such as education of the public and the potential ethical dilemmas that may arise by virtue of these new methodologies, are raised and discussed in this volume, which is based on the 57th RCOG Study Group and includes a set of consensus views from the expert participants. This book provides topical and essential information for practising clinicians, researchers and other healthcare professionals interested in these fields of study.
Reproductive Genetics, Gender and the Body
by Elizabeth EttorreThis book is all about reproductive genetics, a sociological concept developed to define the use of DNA-based technologies in the medical management and supervision of reproduction and pregnant women. In a searching analysis, Elizabeth Ettorre uncovers the hidden social processes involved in the development of these technologies. Focussing on prenatal screening, she explores how the key concepts of gender and the body are intertwined with the process of building genetic knowledge and some of the unintended consequences for women. These include the injection of biology into social relationships and the development of a gendered discourse of shame and stigmatisation in which the perfect body becomes idealised and new conceptions of disability are shaped. It becomes clear that the modernist tradition of scientific disinterestedness is being replaced by a new ethic: the making of moral judgements by scientists. Reproductive Genetics, Gender and the Body draws on interviews with European medical, legal and nursing professionals and raises important issues around the gendered, female body, the site of genetic capital. It challenges professional and scholar alike to grapple with and think through their responsibilities in this complex field where the competing issues have yet to be resolved.

Reproductive Sciences in Animal Conservation: Progress And Prospects (Advances in Experimental Medicine and Biology #1200)
by Pierre Comizzoli Janine L. Brown William V. HoltThis second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences.Understanding reproductive biology is centrally important to the way many of the world’s conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world’s fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 – 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.
Reproductive Sciences in Animal Conservation
by William V. Holt Janine L. Brown Pierre ComizzoliReproductive biology is more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species, technical developments have to be backed up by thorough biological understanding of the background behind the problems. This book is therefore threefold; (1) it provides a snapshot of the state of the art in terms of species-specific reproductive technologies, whether for individual animals or whole taxonomic groups; (2) it sets the reproductive problems in context and emphasizes the links between animal-based problems and the wider world, e. g. reproductive fitness and (3) it looks forward and presents realistic assessments of how effective some of the more recently developed techniques in reproductive technology might be at combating extinctions. This is a wide-ranging book that will be relevant to anyone involved in reproductive biology or in species conservation and provides provide them some useful perspectives about the real utility of current and emerging technologies. It has contributions from experts in reproduction and related fields.
Reproductive Seasonality in Teleosts: Environmental Influences
by Angus D. Munro Alexander P. Scott T. J. LamThis important publication provides, for the first time, a comprehensive review of knowledge of reproductive seasonality in teleosts. It addresses why a particular species should show such seasonality, and how environmental cues act as regulators to ensure that reproductive maturation and breeding occur at the optimum time. The book considers the ultimate factors responsible for the evolution of reproductive seasonality in fish. It reviews salient concepts of reproductive seasonality in mammals. This volume also includes a review of accumulated knowledge of the control mechanisms of salmonids, gasterosteids, temperate cyprinids, cyprinodonts and other brackish-water forms, and marine and tropical freshwater teleosts. This is a work of value to research scientists in the field of environmental physiology, reproductive biology, and comparative neuroendocrinology and endocrinology. In addition, it is relevant for institutions involved with aquaculture and fisheries management. It is useful for post-graduate as well as undergraduate courses in fish biology and various related subjects.

Reprogramming the Brain: A Guide to the Future of the Brain and Neuromodulation by a Patient and his Doctor
by Benjamin Stecher Alfonso FasanoIn June 2021, Doctor and Patient decided that time had come to surgically implant two six-inch-long metal alloy spikes all the way through Ben’s brain. It was felt that the medications Ben was taking to control his Parkinson’s disease had become unmanageable. Back then, Ben was taking about 20 different pills a day. Each pill, if it absorbed properly, would activate the dopamine pathways in his brain and induce uncontrollable writhing movements that would last for about an hour. He would then get about 20 minutes where he’d feel somewhat normal before the slowness and tremor kicked in again. So, he’d take another pill and the cycle would repeat.After months of adjusting his medication and finding just the right settings on his deep brain stimulator, it was decided, for the first time ever in a clinical trial in North America, to flip on the adaptive settings.This is the story of how that decision was made and what happened next.
Reptiles and Amphibians of the Pacific Islands
by George R. ZugThe Pacific is not only the world's largest body of water; its vast expanse also includes an extraordinary number and diversity of oceanic islands, from Palau and the Marianas east of the Philippines to Cocos Island and the Galápagos west of the Americas. The isolation of these islands and the extreme distances between them long prevented scientists from studying their floras and faunas in a comparative context. But now George R. Zug, one of the world's foremost experts on the diverse reptiles and amphibians of the Pacific Basin, offers the first such systematic overview in more than half a century. Reptiles and Amphibians of the Pacific Islands is a compendium of frogs, lizards, snakes, and turtles living on these lands and in the adjacent waters of the oceanic islands in the tropical Pacific. The means to identify each species is included, along with entries that describe each animal's form, coloration, habitat, distribution, reproductive biology, and natural history. Color plates of more than 75 percent of the species also help to facilitate visual identification. This accessible and informative guide is the most comprehensive field guide available and will appeal to both novice sightseers and professional naturalists.

Reptiles of Costa Rica: A Field Guide (Zona Tropical Publications)
by Twan LeendersReptiles of Costa Rica, the long-awaited companion to Amphibians of Costa Rica, is the first ever comprehensive field guide to the crocodilians, turtles, lizards, and snakes of Costa Rica. A popular destination for tourists and biologists because of its biodiversity, the country is particularly rich in reptile fauna, boasting 245 species. The sheer diversity in shapes, sizes, colors, and natural history traits of these animals is beautifully displayed in this book. Lizards range from minuscule dwarf geckos to dinosaur-like iguanids, and everything in between, while the country's snakes include tiny eyeless wormsnakes, massive boas, as well as twenty-three dangerously venomous species, which include the largest vipers in the world. Author, photographer, and conservation biologist Twan Leenders has been researching and documenting the herpetofauna of Costa Rica for nearly twenty-five years. His explorations have taken him to remote parts of Costa Rica that few people ever visit, journeys that usually find him hauling an array of photographic equipment to document his finds. In addition to including more than 1,000 photographs, detailed black and white scientific illustrations, and range maps, this book also features paintings of anole dewlaps, a key identification feature for that very complex group of lizards. This new field guide will enable the reader to identify all species, while also providing a wealth of information about natural history, predation, breeding strategies, habitat preferences, and conservation of Costa Rica's reptile fauna.

The Republic of Color: Science, Perception, and the Making of Modern America
by Michael RossiThe Republic of Color delves deep into the history of color science in the United States to unearth its origins and examine the scope of its influence on the industrial transformation of turn-of-the-century America. For a nation in the grip of profound economic, cultural, and demographic crises, the standardization of color became a means of social reform—a way of sculpting the American population into one more amenable to the needs of the emerging industrial order. Delineating color was also a way to characterize the vagaries of human nature, and to create ideal structures through which those humans would act in a newly modern American republic. Michael Rossi’s compelling history goes far beyond the culture of the visual to show readers how the control and regulation of color shaped the social contours of modern America—and redefined the way we see the world.
