This book is a concise informative elucidation of all aspects of reproduction and development in annelids covering from arenicola to tubifex. Annelids flourish between 4,900 m depth to 2,000 m altitude; some of them occur in unusual habitats like hydrothermal vents and subterranean aquatic system (stigobionts). A few have no gut and acquire adequate nutrients through osmotrophism and/or engaging symbiotic microbes. In the absence of exoskeleton to escape predation, the 17,000 speciose annelids have explored bewildering modes of reproduction; not surprisingly, 42-47% of them are brooders. With 13,000 species, polychaetes are gonochores but some 207 species of them are hermaphrodites. Clitellates are all hermaphrodites; of them, 76 species are parthenogens, of which 56 are earthworms. Regenerative potency of annelids ranges from an organ to an entire worm from a single 'seminal' segment. The head, tail and both together can be regenerated 21, 42 and 20 times, respectively. However, the potency is limited to ~1% of polychaetes and < 2% of oligochaetes. In oligochaetes, the chloragogue temporally separates regeneration and reproduction but sedentary polychaetes undertake them together at the reduced reproductive output. Only 79 polychaete and 111 oligochaete species have the potency for clonal reproduction. Within families, the potency ranges from 2% in spionids to 54% in naidids. Epitoky, a spectacular and unique phenomenon, involves the transformation from benthic to meroplanktonic reproductive morphism. It occurs in 106 errant polychaete species. The larger glycerides, nereidids and eunicids use muscular energy to climb < 50 m vertical distance. But the small phyllodocids and cteniodrilids may reduce buoyancy to climb 1,000-4,000 m vertical distance. Heterogamatic sex determination is reported to occur only in six polychaete species, although karyotype is known for 83 annelid species. In temperate polychaetes, a dozen neuroendocrines, arising mostly from the 'brain' regulates reproductive cycle. A complete chapter devoted to vermiculture, (i) recognizes the fast-growing candidate species, (ii) distinguishes 'layers' from 'brooders', (iii) indicates that the harvest of oligochaetes may reduce the input of nitrogenous fertilizer in the ricefield, and (iv) explores the scope for increasing wealth from waste.

Originally published in 1972, Homo Sapiens examines how humans emerged from among the millions of other species and achieved our unique position within the animal kingdom. The book examines what direction future evolution will take and what may be regarded as the 'meaning' of human existence. It stipulates that these are the questions for which no real basis of discussion existed before the 20th century, and at the time of publication, some were still without a definite answer. The book sets out analyse these questions and the continuing debate that has arisen from their study. This is an account of the uniqueness of man in the animal kingdom, how this uniqueness arose during evolution, and what traces of it can be detected in animals other than man. The book describes the mental and physical evolution of man, from his earliest ancestors to the present day. He also gives an account of man's cultural development seeking to establish that there is an underlying principal of cultural evolution, a principle that has been denied by many historians. Later chapters deal with the future and with possible forecasts of mankind's further physical, intellectual and cultural evolution.

Photopigments are molecules that react to light and mediate a number of processes and behaviours in animals. Visual pigments housed within the photoreceptors of the eye, such as the rods and cones in vertebrates are the best known, however, visual pigments are increasingly being found in other tissues, including other retinal cells, the skin and the brain. Other closely related molecules from the G protein family, such as melanopsin mediate light driven processes including circadian rhythmicity and pupil constriction. This Volume examines the enormous diversity of visual pigments and traces the evolution of these G protein coupled receptors in both invertebrates and vertebrates in the context of the visual and non-visual demands dictated by a species' ecological niche.

The first volume in the new Cambridge Handbooks in Behavioral Genetics series, Behavioral Genetics of the Mouse provides baseline information on normal behaviors, essential in both the design of experiments using genetically modified or pharmacologically treated animals and in the interpretation and analyses of the results obtained. The book offers a comprehensive overview of the genetics of naturally occurring variation in mouse behavior, from perception and spontaneous behaviors such as exploration, aggression, social interactions and motor behaviors, to reinforced behaviors such as the different types of learning. Also included are numerous examples of potential experimental problems, which will aid and guide researchers trying to troubleshoot their own studies. A lasting reference, the thorough and comprehensive reviews offer an easy entrance into the extensive literature in this field, and will prove invaluable to students and specialists alike.

1. First book to adapt and explain health promotion, harm reduction and health equity issues in a One Health context and in terms of animal health. 2. Action oriented, focusing on principles and lessons learned in case studies to demonstrate how to inspire actions to protect the shared health of people, animals and environments. 3. Emphasizes what we can do to keep things healthy, thus addressing the growing calls to shift from a reactive to proactive approach in One Health. 4. Examines One Health in terms of the wider threats to the world, like climate change, thus expanding its scope of practice and helping find common ground between many emerging fields that are trying to co-manage human-animal and environmental health.

This comprehensive volume focuses on recent trends and new technologies used in the management of reproduction in major farm animals, focusing on both males and females of bovine, equine, and porcine species. With chapters written by scientists who specialize in their respective topics, the volume presents a selection of different technologies that have been developed to assure reproductive success by improving reproductive efficiency, generating germplasm banks, and maintaining genetic diversity in cattle, horses, and pigs. In the last decade, reproductive technologies in veterinary medicine have progressed considerably, providing high profitability to livestock farms. This book provides basic and applied information on the most used reproductive technologies in bovine, equine, and porcine species for academics, scientists, and veterinarians. The volume discusses reproductive and postpartum management, reproductive ultrasound, sperm management, egg retrieval, artificial insemination, embryo transfer, nutrition, genetics, and certain clinical aspects, such as endocrinology and robustness of reproductive systems.

Like previous handbooks, the present volume is an authoritative and up-to-date compendium of information and perspective on the neurobiology of ingestive behaviors. It is intended to be stimulating and informative to the practitioner, whether neophyte or senior scholar. It is also intended to be accessible to others who do not investigate the biological bases of food and ?uid ingestion, who may teach aspects of this material or simply wonder about the current state of the ?eld. To all readers, we present this handbook as a progress report, recognizing that the present state of the ?eld is much farther along than it was the last time a handbook was published, but mindful of the likelihood that it is not as far along as it will be when the next handbook is prepared. This ?eld has witnessed a spectacular accretion of scienti?c information since the ?rst handbook was published in 1967. During the generation of science between then and the publication of the second handbook in 1990, numerous scienti?c reports have substantially changed the perspective and informational base of the ?eld.

Blood coagulation and fibrinolysis has been traditionally classed as a part of hematology and the complement system as a part of immunology. An analysis of these two systems at a molecular level, however, has revealed some intriguing evolutionary relationships among some of the macromolecules involved. Evidently, there are similarities in the cascade of reactions that characterize the processes. It is therefore highly suitable that these topics are presented together in one volume. This book presents a thorough explanation and analysis of our current understanding of the proteins and enzymes involved in each of the three processes, and includes a section devoted to special topics of relevance, such as the kinin system, glycosylation, signal peptides, and the serpin family.

The concept of the 3Rs (Refinement, Reduction and Replacement) has been used as a framework for improving the welfare of laboratory animals for the last half century. By establishing an animal-centric view on housing and management, Animal-centric Care and Management: Enhancing Refinement in Biomedical Research takes Russell and Burch's definition of Refinement as "elimination of inhumanities" and goes further. Rather than fitting animals into experimental conditions, it encourages readers to adjust conditions to better meet the behavioral, emotional, physical, and physiological needs and preferences of the animals. The team of expert authors, from the fields of laboratory animal science, ethology, biology as well as animal training, provide ideas for creating housing conditions and handling procedures that induce, to the best of current abilities and knowledge, a long-term positive state of mind in the animals under our care. This book is written for animal caretakers, animal health technicians, researchers, animal facility managers, laboratory animal veterinarians, and anyone who engages in work with living experimental animals or is interested in the continuous improvement of laboratory animal welfare. This interdisciplinary guide will act as a catalyst, resulting in multiple viewpoints and fields collaborating to optimize laboratory animal welfare.

The study of microglial cells has recently gained importance for those researching degeneration and regeneration. Microglia in the regenerating and degenerating CNS supports the assertion that understanding microglial biology could perhaps be pivotal for unraveling the pathogenetic mechanisms that underlie Alzheimer's disease, In addition, microglia are also critical for understanding the sequelae of traumatic brain and spinal cord injury, and for the important post-traumatic repair processes. This book gives an up to date account of the role of microglia in degeneration and regeneration of the nervous system and reviews their cell function and physiology.

The fifth edition of The Physiology of Fishes represents a compendium of knowledge across fish physiology, collecting up-to-date research into an easy-to-access single textbook. Written by the leaders in the field, it provides a comprehensive, accessible review of the core topics, integrating physiology with environmental science, ecology, evolution, and molecular cell biology. New chapters address Epigenetics, Biomechanics and Locomotion, and Behaviour and Learning. Each chapter contains an extensive bibliography, providing readers with the best sources from the primary literature. Almost three decades after the publication of the first edition, this book remains the only published single-volume work on fish physiology. The fifth edition provides an important reference for new students of fish biology, marine and freshwater biologists, ichthyologists, fisheries scientists, and comparative physiologists.

Sense organs serve as a kind of biological interface between the environment and the organism. Therefore, the relationship between sensory systems and ecology is very close and its knowledge of fundamental importance for an understanding of animal behavior. The sixteen chapters of this book exemplify the diversity of the constraints and opportunities associated with the sensation of stimuli representing different forms of energy. The book stresses the events taking place in the sensory periphery where the animal is exposed to and gets in touch with its natural habitat and acquires the information needed to organize its interaction with its environment. Ecology of Sensing brings together the leading experts in the field.

This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

The book "Parasitic Zoonoses" emphasizes a veterinary and public health perspective of zoonotic parasites. This book is suitable for higher undergraduate and graduate students of zoonoses and public health, veterinary parasitology, parasite epidemiology; public health workers; public health veterinarians; field veterinarians, medical professionals and all others interested in the subject. More than 15 protozoa and 50 other parasitic diseases are zoonotic in nature and all these diseases have been discussed in detail. The first chapter is concerned with classification of zoonotic parasites, food borne, vector borne and occupation related zoonotic parasites. The remaining chapters cover etiology, epidemiology, life cycle, transmission, clinical signs, diagnosis, prevention and control of zoonotic parasites. The text is illustrated with a large number of coloured figures. An alphabetical bibliography for every disease has also been included so that readers have access to further information.

Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture. This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented. Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.

The nature .and diversity of presentations at the conference on: "Bee Products: Prop erties, Applications and Apitherapy" held at Tel-Aviv on May 26--30, 1996, emphasize the increasing interest of physicians, practitioners, scientists, herbalists, dieticians, cosmeti cians, microbiologists, and beekeepers in different facets of bee products. This volume consists of a selection of 31 contributions presented at the conference and which provide information on the present status of our knowledge in this area. In spite of their diversity, they reflect the mainstream of the conference, namely: "Imported" Prod ucts (honey, pollen and propolis), Exocrine Secretions of Workers (venom, royal jelly). Toxicity and Contaminants, Quality Control, Marketing, Apitherapy, Cosmetics, etc. Since antiquity, honey as well as other bee products were used as food, as a cure for ailments of humans and animals, and as cosmetics. We hope that this volume will contribute to interdisciplinary studies on chemical composition, pharmacological effects, nutrition, and other aspects of bee products. Critical and unbiased experimental research may unravel the yet unknown composition and mode of action of bee products and elucidate many unanswered questions. The noteworthy features of this conference were the participants from all parts of the world and of different cultural backgrounds, who shared their keen interest and curios ity regarding honey bees and their products. We thank all of them for their personal con tribution to the success of this conference."

I have been asked to write a brief foreword to this volume honoring Hisako Ikeda, providing a review of the accomplishments in our field over the past four decades, when Hisako was an active participant. This I am delighted to do. It has been a most exciting time in vision research and Hisako has been right in the middle of much of the excitement, publishing on a wide variety of topics and providing much new data and many new insights. Hisako's research career can be divided by decades into four quite distinct areas of inquiry. In the 1950s, as a student in Japan, her research interests were psychophysical in nature, and she was concerned with visual illusions, figural aftereffects, and motion detec tion. In the 1960s, after her move to London, she began electrophysiological studies. Much of her work in the 1960s was concerned with the electroretinogram (ERG), its components, and the use of this electrical response for evaluating spectral sensitivities of the eye and retinal degenerations. This work represented the beginning of her electrodiagnostic clinical work, which continued until her retirement."

The following are the proceedings of the Third International Workshop on Perception held in Pavia, Italy, on September 27-30, 1993, under the auspices of four institutions: the Group of Cybernetic and Biophysics (GNCB)s of the National Research Council (CNR), the Italian Association for Artificial Intelligence (AI * IA), the Italian Association of Psychology (AlP), and the Italian Chapter of the International Association for Pattern Recognition (IAPR). The theme of this third workshop was: "Human and Machine Vision: Analogies and Divergencies." A wide spectrum of topics was covered, ranging from neurophysiology, to computer architecture, to psychology, to image understanding, etc. For this reason the structure of this workshop was quite different from those of the first two held in Parma (1991), and Trieste (1992). This time the workshop was composed of just eight modules, each one consisting of two invited lectures (dealing with vision in nature and machines, respectively) and a common panel discussion (including the two lecturers and three invited panellists).

This book is a concise informative elucidation of all aspects of reproduction and development in annelids covering from arenicola to tubifex. Annelids flourish between 4,900 m depth to 2,000 m altitude; some of them occur in unusual habitats like hydrothermal vents and subterranean aquatic system (stigobionts). A few have no gut and acquire adequate nutrients through osmotrophism and/or engaging symbiotic microbes. In the absence of exoskeleton to escape predation, the 17,000 speciose annelids have explored bewildering modes of reproduction; not surprisingly, 42-47% of them are brooders.

The larger glycerides, nereidids and eunicids use muscular energy to climb < 50 m vertical distance. But the small phyllodocids and cteniodrilids may reduce buoyancy to climb 1,000-4,000 m vertical distance. Heterogamatic sex determination is reported to occur only in six polychaete species, although karyotype is known for 83 annelid species. In temperate polychaetes, a dozen neuroendocrines, arising mostly from the 'brain' regulates reproductive cycle. A complete chapter devoted to vermiculture, (i) recognizes the fast-growing candidate species, (ii) distinguishes 'layers' from 'brooders', (iii) indicates that the harvest of oligochaetes may reduce the input of nitrogenous fertilizer in the ricefield, and (iv) explores the scope for increasing wealth from waste.

Feed represents the single greatest expense associated with bringing pigs to market weight. Therefore, if you can reduce the cost of feeding without detriment to pig performance, the economics of swine production will improve. The ingredient list for swine rations has become fairly limited, and the majority of diets fed to pigs consist of a few staples, such as corn, wheat, barley, and soybean meal. Non-Traditional Feeds for Use in Swine Production explores over fifty non-traditional feedstuffs in terms of their nutritional content and their viability as alternative, cost effective food sources

This book describes the development of horse behaviour, and the way in which the management of horses today affects their welfare. Horses for sport, companionship and work are considered and ways of improving their welfare by better training and management is described. The book assesses welfare, nutrition, and behaviour problems with horses. The authors include internationally-recognised scientists from Britain, Ireland, USA and Australia.

This second edition offers a comprehensive overview of the physiological functions of vertebrate kidneys from a comparative viewpoint, with particular emphasis on nonmammalian vertebrates. The topics covered include renal structure; glomerular ultrafiltration; tubular transport of inorganic ions, organic substances, and fluid; and urine dilution and concentration. Mammalian renal function is only considered for purposes of comparison with nonmammalian renal function and as a frame of reference for some of the discussions. The major findings on nonmammalian renal function and the important unanswered questions raised by those findings are described in detail. As such, the book provides comprehensive information on comparative renal function for biological scientists and advanced students of biology with some knowledge of physiology and a desire to know more about renal function in vertebrates, and for mammalian renal physiologists who wish to obtain a broader view of renal function.

The past decade has seen an exponential increase in our knowledge and understanding of adipose tissue biology. This has coincided with the continued rise in obesity across all generations. Clearly despite substantial advances in research into adipose tissue this still has had limited impact on the on-going obesity epidemic across a majority of countries in the world. This book brings together many leading experts in the field to provide an up to date and comprehensive review of the key aspects of adipose tissue. It therefore includes chapters on evolution, development and inflammation together with a detailed review of brown and beige adipose tissue biology and their potential significance in preventing or combating obesity. These chapters are complemented by those on genetics and gender influences, together with nutrition through the life cycle. Ultimately the book provides an overview of the complexities of adipose tissue biology and the continuing challenge to combat obesity in the 21st century.
