The unusual life history of the brine shrimp, Artemia, and the relative ease with which it can be experimentally manipulated have long made his crustacean a favorite system for biological studies. Over the years, descriptive morphological work has given way to a rigorous analysis of biochemical and cellular aspects of the organism. The underlying theme of the work is often been developmental in nature.This book brings together a wide spectrum of topics under study in the shrimp. Analyses of gene structure and protein synthesis are combined with descriptions of protein interactions characteristic of functional cells.

Egg transfer was first performed in 1890, but for half a century it received scant attention. However, since 1950 the technique has become increasingly widely used - in the laboratory for fundamental studies and more recently in practice, both veterinary and medical, to boost reproductive potential of genetically superior cattle and to overcome sterility due to impaired rubal function in women. As a result, a considerable body of literature has accumulated, totaling well in excess of a thousand references. But till now there has not been a single comprehensive text devoted solely to this subject. The present work was designed to meet that need at a time when the field is fast expanding with new techniques and approaches constantly being evolved. One need only cite the tremendous rate of progress in human egg transfer in the last three years. The work embraces laboratory and farm animals and primates, including man, altogether representing a total of 16 species.

These volumes provide information which will be helpful to comparative pathologists, veterinarians, and all marine scientists and other individuals who are interested in the study of marine mammals, and the diseases they develop in both their feral and captive environment.This publication is a reflection of the observations of the various authors, some of whom have pioneered in this field, and is an attempt to update the available information concerning the natural diseases, and the corresponding pathologic changes in marine mammals.

The greatest challenge of our time is to produce sufficient food ot keep pace with the rapidly growing population. In the opinion of experts, during the next 25 years there will be a need for as much food as was produced in the entire history of mankind to date. Of the various measures available, improvement in agricultural productivity is judged as the ultimate means of augmenting food production and supplies. In this Handbook, an international team of experts consider the most important factors affecting production of both crops and livestock. This Handbook is intended as a scientific guide to practitioners and students, as well as to researchers, who should find here stimulating ideas for further exploration.

This work offers comprehensive, up-to-date coverage of cytokine biology in veterinary and agricultural species, describing the role of cytokines in physiological and pathological processes. It addresses recent advances and new information on the function of cytokines in reproduction, detoxification of xenobiotics, growth modulation and other areas, and discusses the approaches to and pitfalls of studying cytokines in animals.

The aim of the present volume was to give an overview over different available methodological approaches. The specialists may, perhaps, object that in their particular field the level of information is superficial. However, let them look at other chapters in which different approaches are discussed and which, surely, will appear less superficial from the more general point of view. We hope, at least, that crucial references can be traced throughout the book that would enable the readers to go in more detail when desired. It can be traced throughout the book that would enable the readers to go in more detail when desired. It was really one of our ideas to draw the survey of possibilities available. If this can stimulate the readers to use ideas to draw the survey of possibilities available. If this can stimulate the readers to use other methods that those they are routinely using the goals will be met.

This book is focused on the principals and methods of using growth layers formed in teeth and bones of mammals and to make a judgement on essential traits of the animal's life history. Nearly in all mammalian species including man, the age of individuals can be determined from the number of growth layers and, at least in some of them, it is possible to estimate the season of an animal's birth and death, the age of sexual maturation, periodicity of reproduction, certain feeding habits and other aspects of the individual's biology. It is also possible, from tooth enamel analysis, to assess dose of radiation accumulated by animals and human beings during their lifetime. The book is intended mainly for zoologists, wild-game biologists, and zoo-archaeologists, but some of the sections can also be of interest for anthropologists, radio-ecologists and conservation biologists.

The reviews in this collection are unique in their intent to provide a basis for understanding of the subject. They include historical, descriptive, and comparative information which is not always presented in state of the science reviews. Cholesterol is viewed in each chapter as part of a system structural, kinetic, or metabolic. The complex nature of the place of cholesterol in living systems is illustrated in each chapter.

The major objective of this handbook is to compile-in tabular form-the pharmacokinetic parameters of antimicrobial drugs used in food animals. This unique publication represents data from the FARAD (Food Animal Residue Avoidance Databank) databank, established by the authors under the auspices of the U.S.D.A. and contains significant amounts of previously unavailable information. This updated, one-of-a-kind volume even features additional data on laboratory rodents, dogs, cats, and horses in order to facilitate broader interspecies extrapolations. This easy-to-use reference is timely as well as invaluable to animal scientists, veterinarians, pharmacologists, and toxicologists who work with antimicrobials in chickens, turkeys, dairy and beef cattle, swine, goats, and sheep.

Bioenergetics is an emerging discipline which offers a more profound understanding of the ecology, behaviour, and evolution of wild herbivores. Increasingly, bioenergetic principles have been applied in management since they provide insight into population dynamics and are relevant to manipulation of habitats and assessment of the impacts of resource development. Growing interest in the agricultural potential of wild herbivores has provided further impetus. In spite of this promise, there are few comprehensive syntheses of the concept and its application to wild herbivores. This volume attempts to fill this need. This book provides a great amount of detail but its expressive aim is to lead us to the whole animal, to a herd, to population as integral parts of an ecological entity which in turn is the result of evolutionary forces.The concept of this book promises the realization of an overdue change in the approach to bioenergetics, to nutrition and husbandry, and thus to the management of wild herbivores: the final emancipation from rules and views based primarily on domesticated herbivores or on experimental animals held under unnatural conditions, necessarily impending them behaviourally, physically, and psychically.

This book is primarily a monograph of the reproductive diversity among animals, including protozoans. This diversity is listed for each group in Chapter 6; it is cross-listed by process in chapter 7.

Accumulation into one source of what is known regarding the feeding value of these materials and systems which have been developed for improving their digestibility, palatability or methods of handling was the motivation for organising this book. These has been an effort to include the major categories of unconventional materials which can potentially be upgraded to provide the ruminant with needed nutrients, but certainly some have been missed. It is hoped that this treatise will prove to be a valuable tool for workers involved in improving the utilization of residues and waste products for animals.

This book presents a comprehensive and coherent picture of how molecules diffuse across a liquid that is, on average, only two molecules thick. It begins by characterizing bilayers structurally, using X-ray diffraction, and then mechanically by measuring elastic moduli and mechanisms of failure. Emphasis is placed on the stability and mechanical properties of plant membranes that are subject to very large osmotic and thermal stresses. Using this information, the transport of molecules of increasing complexity across bilayers is analyzed.

The present book deals with the biology of a wide range of coccidia of numerous genera including Emeria, Isospora, Sarcocystis, Toxoplasma, Caryospora, and Cryptosporidium. The book will be valuable for advanced undergraduates, graduate students, research workers, and teachers in biology, especially useful for parasitologists teaching the subject and essential for coccidiologists doing research on coccidia. The book has also an appeal for physicians, veterinarians, and zoologists needing an update of information in the general field of coccidiosis

Molt is an important avian life history event in which feathers are shed and replaced. The timing, duration, seasonality, extent and pattern of molt follows certain strategies and this book reviews and describes these strategies for nearly 190 species based on information gathered from a 30-year study of Central Amazonian birds. Most species accounts are illustrated with several color photos focusing on wing and tail feather molt, molt limits, and how to use these patterns to accurately age birds. Published in collaboration with and on behalf of the American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series is a rich source of life history information for ornithologists working on tropical birds.

Handbook of Comparative Pharmacokinetics and Residues of Veterinary Therapeutic Drugs is a unique compilation of comparative pharmacokinetic data for veterinary therapeutic drugs. The book features an excellent introductory chapter on basic veterinary pharmacokinetics and includes pharmacological data taken from hundreds of primary research references. These data are presented in standardized units and are arranged in conveniently organized tables so that comparisons between data can be made easily. Much of the data is new and was taken from articles in which data was not subjected to pharmacokinetic analysis.

A major problem with vampire bats is that whatever information exists is scattered throughout the literature or is not recorded. There are some excellent books on the ecology and biology of bats with very little on vampire bats. This volume fills that gap to provide an in-depth presentation of these unique animals.

The objective of this multi-authored compendium is, therefore, to bring together the state of arts reported in one place. Written by specialists by specialists in various fields of rondentology, and to suggest future lines of research. It is also felt that this work on rodent pest management will trigger more research effort for the benefit of mankind and help certain countries and organizations in revitalizing serious work in this field which, it appears, has dampened during the last few years.

This updated monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further chapters discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other "methanogenic" mammals contribute significantly to the global methane budget; especially the rumen hosts an impressive diversity of methanogens. This makes this updated volume an interesting read for scientists and students in Microbiology and Physiology.

Laboratory animals are becoming increasingly important for biomedical research. It is said that approximately 70% of biomedical research is associated with the use of experimental animals. Laboratory animal research not only expands our knowledge of science, but also greatly improves human and animal health. The field of laboratory animal science is ever-growing and changing as new experimental techniques are developed and new animal models are created. It is essential to know not only the biological features of each laboratory animal but also how to use and care for them responsibly in order to perform high-quality experiments. Courses in beginning Laboratory Animal Science are starting to be offered in many universities throughout the world. However, a practical introductory textbook that contains state-of-the-art techniques is still lacking. Fundamentals of Laboratory Animal Science provides comprehensive information on the principles and practices of using laboratory animals for biomedical research. Each individual chapter focuses on a key sub-discipline of laboratory animal science: animal welfare and best humane care practices in the laboratory; the quality control of laboratory animals; the anatomy, physiology, and husbandry of commonly used species; the principles of creating and using animal models for studying human diseases; practical techniques used for laboratory animal experiments; experimental design; and animal experimentation management. Knowledge of this broad spectrum of concepts and skills will ensure research goes smoothly while greatly reducing animal pain and distress. Well-illustrated and thoroughly referenced, this book will serve not only as a standard textbook but also as a handy guide for veterinarians, researchers, animal care staff, administrators, and other professionals who are involved in laboratory animal science.
