The capybara is the neotropical mammal with the highest potential for production and domestication. Amongst the favorable characteristics for domestication we can list its high prolificacy, rapid growth rate, a herbivorous diet, social behavior and relative tameness. The genus (with only two species) is found from the Panama Canal to the north of Argentina on the east of the Andes. Chile is the only country in South America where the capybara is not found. The species is eaten all over its range, especially by poor, rural and traditional communities engaged in subsistence hunting. On the other hand, in large urban settlements wildlife is consumed by city dwellers as a delicacy. The sustainable management of capybara in the wild has been adopted by some South American countries, while others have encouraged capybara rearing in captivity.

A COLLECTION OF ESSAYS PLACING THE HUMAN - WOLF RELATIONSHIP IN HISTORICAL PERSPECTIVE International in range and chronological in organisation, this volume aims to grasp the maincurrents of thought about interactions with the wolf in modern history. It focuses on perceptions, interactions and dependencies, and includes cultural and social analyses as well as biological aspects. Wolves have been feared and admired, hunted and cared for. At the same historical moment, different cultural and social groups have upheld widely diverging ideas about the wolf. Fundamental dichotomies in modern history, between nature and culture, wilderness and civilisation and danger and security, have been portrayed in terms of wolf - human relationships. The wolf has been part of aesthetic, economic, political, psychological and cultural reasoning albeit it is nowadays mainly addressed as an object of wildlife management. There has been a major shift in perception from dangerous predator to endangered species, but the big bad fairytale wolf remains a cultural icon.

This book examines the biology of tuco-tucos (Ctenomys) from an evolutionary perspective. Historically, these subterranean rodents have long attracted the attention of scientists due to its remarkable chromosomes variability and rapid diversification. A wealth of knowledge on physiology, ecology, genetics, morphology, paleontology, and taxonomy has been documented in the last 70 years through numerous single publications. In this volume, expert investigators review and frame these essays with the breadth of current understanding. The collection of chapters are presented into the major topics: i) Evolution of Ctenomys, ii) Geographic Patterns, iii) Organismal Biology, and iv) Environmental Relationships. Given its scope, the book will be of interest to both students and researchers and may stimulate further research with this exciting model on a wide range of evolutionary topics.

Felines of the World: Discoveries in Taxonomic Classification and History provides the most recent taxonomic, paleontological, phylogenetic and DNA advances of wild felid and domestic cat species following guidelines dictated by the IUCN SSC Cat Specialist Group. It highlights the importance of felines and their role as predators in maintaining the ecological biome balance in which they have evolved. The book delves into the anatomical, evolutionary and zoogeographic features of fossil and current felid species. Each species is described in detail, detailing its classification, habitat and biological habits. This book also presents the most updated threat and conservation status of each species. This book is an ideal resource for zoologists and paleontologists, primarily those interested in the evolution and features of extinct and extant felines.

Receptors in the Evolution and Development of the Brain: Matter into Mind presents the key role of receptors and their cognate ligands in wiring the mammalian brain from an evolutionary developmental biology perspective. It examines receptor function in the evolution and development of the nervous system in the large vertebrate brain, and discusses rapid eye movement sleep and apoptosis as mechanisms to destroy miswired neurons. Possible links between trophic deficits and connectional diseases including Alzheimer's, Parkinson's, and ALS are also discussed. This book is extremely useful to those with an interest in the molecular and cellular neurosciences, including those in cognitive and clinical branches of this subject, and anyone interested in how the incredibly complex human brain can build itself.

‘Steve Brusatte, the author of The Rise and Fall of the Dinosaurs, brings mammals out from the shadow of their more showy predecessors in a beautifully written book that . . . makes the case for them as creatures who are just as engaging as dinosaurs.’ – The Sunday Times, ‘Best Books For Summer’ 'In this terrific new book, Steve Brusatte . . . brings well-known extinct species, the sabre-toothed tigers and the woolly mammoths, thrillingly back to life' – The Times The passing of the age of the dinosaurs allowed mammals to become ascendant. But mammals have a much deeper history. They – or, more precisely, we – originated around the same time as the dinosaurs, over 200 million years ago; mammal roots lie even further back, some 325 million years. Over these immense stretches of geological time, mammals developed their trademark features: hair, keen senses of smell and hearing, big brains and sharp intelligence, fast growth and warm-blooded metabolism, a distinctive line-up of teeth (canines, incisors, premolars, molars), mammary glands that mothers use to nourish their babies with milk, qualities that have underlain their success story. Out of this long and rich evolutionary history came the mammals of today, including our own species and our closest cousins. But today’s 6,000 mammal species - the egg-laying monotremes including the platypus, marsupials such as kangaroos and koalas that raise their tiny babies in pouches, and placentals like us, who give birth to well-developed young – are simply the few survivors of a once verdant family tree, which has been pruned both by time and mass extinctions. In The Rise and Reign of the Mammals, palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and ground-breaking book, Steve Brusatte tells their – and our – story.

By far, the most widely used subjects in psychological and biological research today are rodents. Although rats and mice comprise the largest group of animals used in research, there are over 2,000 species and 27 families of rodents, living all over the world (except Antarctica) and thriving in many different habitat types. The vast environmental diversity that rodents face has led to numerous adaptations for communication, including vocalizing and hearing in both the sonic and ultrasonic ranges, effectively communicating in the open air and underground, and using vocalizations for coordinating sexual behavior, for mother-pup interactions, and for signaling an alarming situation to the group. Some rodent species have even developed foot drumming behaviors for communication. Comparative studies from around the globe, using both field and laboratory methodologies, reveal the vast differences in acoustic communication behavior across many rodent species. Some rodents are amenable to training and have been domesticated and bred purely for research purposes. Since the early 1900s, rats and mice have been indispensable to research programs around the world. Thus, much of what we know about hearing and vocalizations in rodents come from these two species tested in the laboratory. The sequencing of the mouse genome in 2002, followed by the rat genome in 2004, only increased the utility of these animals as research subjects since genetically engineered strains mimicking human diseases and disorders could be developed more easily. In the laboratory, rats and mice are used as models for human communication and hearing disorders and are involved in studies on hearing loss and prevention, hormones, and auditory plasticity, to name a few. We know that certain strains of mice retain hearing better than others throughout their lifespan, and about the genes involved in those differences. We know about the effects of noise, hormones, sex, aging, and circadian rhythms on hearing in mice and other rodents. We also know about normal hearing in many families of rodents, including the perception of simple and complex stimuli and the anatomy and physiology of hearing and sound localization. The importance of acoustic communication to these animals, as well as the significance of these mammals to biomedical research, are summarized in the chapters.

More is known about the behavior, anatomy, and molecular biology of the laboratory rat than any other animal species. Although its natural history and psychological functions have been described previously in books, this is the first comprehensive description of its behavior. Both seasoned and beginning investigators will be amazed at the range and complexity of the species as described in the 43 chapters of this volume. The behavioral descriptions are closely tied to the laboratory methods from which they were derived, thus allowing investigators to correlate the behavior and methods and exploit them in their own research. This book is aimed at investigators in neuroscience who may not be familiar with rat behavior, but who wish to incorporate behavioral studies into their own research. Nevertheless, seasoned investigators will also find the book to be a handy reference for behavioral paradigms with which they may not be familiar. It is expected that as the genetic and molecular understanding of the rat develops, there will be an increasing need for knowledge about rat behavior. This book will serve as an indispensable resource for neuroscientists, psychologists, pharmacologists, geneticists, molecular biologists, zoologists, and their students and trainees.

Cheetahs: Biology and Conservation reports on the science and conservation of the cheetah. This volume demonstrates the interdisciplinary nature of research and conservation efforts to study and protect the cheetah. The book begins with chapters on the evolution, genetics, physiology, ecology and behavior of the species, as well as distribution reports from range countries. These introductory chapters lead into discussions of the challenges facing cheetah survival, including habitat loss, declining prey base, human-wildlife conflict, illegal trade, and newly-emerging threats, notably climate change. This book also focuses on conservation strategies and solutions, including environmental education and alternative livelihoods. Chapters on the role of captive cheetahs to conservation and the long-term research of the species are included, as are a brief discussion of the methods and analyses used to study the cheetah. The book concludes with the conservation status and future outlook of the species. Cheetahs: Biology and Conservation is a valuable resource for the regional and global communities of cheetah conservationists, researchers, and academics. Although cheetah focussed the book provides information relevant to the study of broader topics such as wildlife conservation, captive breeding, habitat management, conservation biology and animal behaviour.

A review of our understanding of this area of the brain, showing how it fits into the general picture of those areas concerned with modulating mammalian behavior. The chapters, all written by leading figures in behavioral neuroscience, discuss the anatomy, neurochemistry, physiology, and behavioral relations in the septal area. Due to the great deal of current research shown in the related areas of hippocampus and the amygdala, this book will be of great interest to all those who research the hippocampus and the amygdala in addition to the septum itself.

From the Preface
The major change in the format of the fifth edition is the presentation of the book in two volumes, necessitated by the rapidly increasing knowledge of metabolism, interactions, and requirements of trace elements. The guiding principle was to present the minimum of results that would serve as a logical foundation for the description of the present state of knowledge.

From the Preface
The major change in the format of the fifth edition is the presentation of the book in two volumes, necessitated by the rapidly increasing knowledge of metabolism, interactions, and requirements of trace elements ... The guiding principle was to present the minimum of results that would serve as a logical foundation for the description of the present state of knowledge.
Recent results of research were accommodated by devoting new chapters to the subjects "Methodology of Trace Element Research" and "Quality Assurance for Trace Element Analysis" and by expanding the discussion of lithium and aluminum in separate, new chapters. The first two subjects are of outstanding importance as determinants of future progress. The concern for the quality of analytical data motivated the authors of the individual chapters to review critically and, where necessary, revise analytical data presented in the previous editions. The rapid progress of trace analytical methodology since the mid-1970s has changed what had been accepted as normal for the concentrations of many trace elements in tissues and foods. The new data reflect the present state of the art in trace element analysis, but they may be subject to future revision.

Mammals range in body size from the gigantic blue whale to the tiny Etruscan shrew. Elephants and man may live for nearly one hundred years, while most shrews die before they are three months old. During the past decade, mammalogists and evolutionary biologists have begun to unravel the numerous factors that shape the enormous diversity of mammal life histories. In this volume, leading scientists provide a variety of perspectives on the newest theories in this active field of study. The principle uniting all studies of life history evolution is adaptation by natural selection. The first chapters in the book discuss this topic, offering evolutionary interpretations of geographic variation in mammal life histories, explaining how natural selection operates in fluctuating environments, introducing evolutionary predictions of demographic mathematics, and integrating life histories with behavioral ecology. The next chapters offer functional interpretations of the importance of body size in the life history. Next, several essays explain how developments in quantitative genetics have enabled us to distinguish between genetic and environmental components of variation within and between species. With this as a basis, the chapters that follow draw from principles of natural selection, allometry, and genetics to interpret differences among species of mammals. The book concludes with speculations on various areas where research seems most urgent for the development of a comprehensive understanding of mammal life history evolution. According to the authors, the field is rich with questions, and opportunities abound for both theoretical and empirical research.

"The Biology and Identification of the Coccidia (Apicomplexa) of Rabbits of the World" is a taxonomic summation of a damaging intestinal parasite found in rabbits and transmissible to other species, including humans. This book conceptually and historically summarizes the world's literature on the parasite and also provides a quick guide to isolation procedures, identification, strategies for management, and available chemotherapy. It is a vital source of knowledge about coccidia s real and potential transmission to humans, which can lead to dangerous health problems, like severe dehydration, vomiting, lethargy and even death.

Coccidiosis is an intestinal disease that affects several different animal species, including canines and humans, and is one of the most prevalent protozoal infections in North America. The causative agent is a protozoan that has the ability to multiply rapidly and cause major damage in the intestinal wall, rupturing the cells of the intestinal lining. The final stage, the oocyst, is extremely resistant to environmental stress and is difficult to completely remove from the environment. Oocysts are frequent contaminants of feed and water and when the sporulated oocysts are ingested by other animals, they start the life cycle over in the new host. With the demand for rabbits in scientific research and for rabbit meat for human consumption increasingly globally each year, rabbits are of epidemiologic significance for laboratory workers, university researchers, veterinarians, pet owners, and breeders.
Evaluates the scientific and scholarly merit of each of the publications written about coccidian from every rabbit species, providing a complete historical renditionA treatise for the identification of coccidia and their treatment as neededWritten in a style that can be understood by most educated lay persons and laboratory workersWritten by the first ranked author team among the world-class parasitologists who study coccidiaCombined in one single source, this book follows the gold standards in coccidian biology and identificationBrings all that information together in one volume and solves the problems faced by researchers, veterinarians, students and others in trying to find and navigate through this scattered literature"
