Because carnivores are at the top of the food chain, their status is an important indicator of the health of the world ecosystem. They are intensely interesting to zoologists and uniquely intriguing to the general public. Devoted primarily to terrestrial carnivores, this volume focuses on such themes as carnivore reintroduction programs and the ethics of studying carnivores, drawing examples from a variety of species.

Wild grizzly bears, conducting their affairs undisturbed, are the essence of the wilderness spirit. Much has been written, both fact and fiction, about these awesome animals, but until very recently we have known little about the details of their daily existence.

For twenty-five years, Adolph Murie, one of North America's greatest naturalists, spent his summers in Mount McKinley National Park (since renamed Denali National Park) tracking, recording, and interpreting the lives of these magnificent animals in one of their few remaining strongholds. Murie observed the grizzlies as they moved throughout their range. He noted how families were formed, how they found food, and he described in detail how they related to other animals with whom they came in contact, including man. Often he followed a bear family for days as it traveled through the park. Even though their behavior could be quite unpredictable, Murie was able to distinguish, through careful observation, the individuals who made up many distinct families.

Originally available only in government publications which are long out of print, this classic work of natural history is now published which are long out of print, this classic work of natural history is now published for the first time in a popular edition. This edition is being published simultaneously with Adolph Murie's other classic study of the Far North, "The Wolves of Mount McKinley", thus making widely available two of the most important studies on North American wildlife.

Since the appearance of the second edition of Sydney A. Asdell's widely used Patterns of Mammalian Reproduction in 1964, the field of reproductive physiology has expanded dramatically. Accordingly, this revision adopts a different structure from previous editions, substituting empirical delineations for physiological interpretations. With the emphases now on a presentation of the published facts of mammalian reproduction, it provides a thorough compilation of what is known about the basic reproductive biology of each of the 4300 mammalian species.To gather information, the authors examined more than 20,000 publications, dating up to 1992. They used primary sources as much as possible, supplementing them with English translations of Russian, Finnish, Chinese, and Japanese journals. The data are presented in taxonomic order. Each familial account summarizes the pattern of reproduction for the family and provides lists of citations arranged by topic of the literature on the endocrinology, reproductive anatomy, and reproductive physiology of the family. Following each account is a tabular listing of species-specific data for neonatal mass and size, weaning mass and size, litter size, age at sexual maturity, estrous cycle length, gestation length, lactation length, number of litters per year, and seasonality of reproduction. For each of these reproductive variables, the range of data gleaned from the literature is given, together with the source of each value listed.Virginia Hayssen is Assistant Professor of Biology at Smith College. Ari Van Tienhoven is Professor of Animal Physiology, Emeritus, at Cornell University. Ans Van Tienhoven assisted in the compilation of data for the book.

Designed to enable newcomers to electrophysiology to choose appropriate preparations and techniques for in vitro studies in vertebrate neurobiology. Emphasizes techniques involving the glass micropipette and other recently developed methods, supplementing easy-to-follow instructions with illustrative schemes, examples of original records, photomicrographs, key word listings, comprehensive reference tables and a list of suppliers and key equipment and reagents.

From a modest beginning in the form of a little shrew-like, nocturnal, insect eating ancestor that lived 200 million years ago, mammals evolved into the huge variety of different kinds of animals we see today. Many species are still small, and follow the lifestyle of the ancestor, but others have adapted to become large grazers and browsers, like the antelopes, cattle, rhinos, and elephants, or the lions, hyaenas, and wolves that prey upon them. Yet others evolved to be specialist termite eaters able to dig into the hardest mounds, or tunnel creating burrowers, and a few took to the skies as gliders and the bats. Many live partly in the water, such as otters, beavers, and hippos, while whales and dugongs remain permanently in the seas, incapable of ever emerging onto land. In this Very Short Introduction T. S. Kemp explains how it is a tenfold increase in metabolic rate - endothermy or "warm-bloodedness" - that lies behind the high levels of activity, and the relatively huge brain associated with complex, adaptable behaviour that epitomizes mammals. He describes the remarkable fossil record, revealing how and when the mammals gained their characteristics, and the tortuous course of their subsequent evolution, during which many bizarre forms such as sabre-toothed cats, and 30-tonne, 6-m high browsers arose and disappeared. Describing the wonderful adaptations that mammals evolved to suit their varied modes of life, he also looks at those of the mainly arboreal primates that culminated ultimately in Homo sapiens. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Among the most widespread and abundant of the world's larger mammals, deer have been a source of endless fascination for humans beings. Yet over the centuries we have hunted them for sport and for their meat, hides, and antlers, and pursued them as destructive pests.In this richly informative and engagingly written book, Rory Putnam captures the astonishing diversity in habitat, diet, social organization, and behavior of the world's 40 species of deer, and tells what is known about their biology and natural history. Rather than simply assembling species-by-species data, he compares and contrasts the characteristics of the various species and accounts for their similiarities and differences in reference to the environments they have come to colonize.After discussing the origins of deer, Putnam describes the species of modern deer and their evolutionary relationships. He considers aspects of their physiology, ecology, and behavior, drawing particular attention to the ecology of habitat use, diet and digestive physiology, and social organization and behavior. He covers the life histories of the different species, population dynamics, and the interactions of deer with other animals.Devoting a whole chapter to an essay on antlers, he ends with an enlightening and entertaining analysis of the relations between deer and humans.Generously illustrated with stunning color and black-and-white photographs, as well as many line drawings and figures, this book will both reward the amateur naturalist and please the professional biologist."

The chromosome complement (karyotype) often differs between related mammalian species (including humans vs chimpanzees), such that evolutionary biologists muse whether chromosomal difference is a cause or a consequence of speciation. The common shrew is an excellent model to investigate this problem because of its many geographical races (potential species) differing chromosomally, and its several sibling species (recently speciated forms) that are also chromosomally different. This system is an exceptional opportunity to investigate the role of chromosomes in speciation and this volume reflects detailed research following these approaches. Highlights include the demonstration that chromosomal re-arrangements can be associated with complete loss of gene flow and thus speciation and that selection within species hybrid zones may lead to de-speciation rather than speciation. This book represents an extraordinarily detailed consideration of the role of chromosomes in speciation in one astonishing species, providing insights to those interested in mammalian diversity, chromosomal evolution and speciation.

In this comprehensive account of olfactory communication and territorial behavior in the Mongolian gerbil, Del Thiessen and PaulineYahr provide the first detailed study of the neurological and physiological mechanisms that control these basic functions. In addition to explaining the links between hormones, genes, olfactory cues, and territorial acts, they also offer a more general picture of gerbil behavior, as well as a brief look at other mammalian species that communicate social status by way of olfactory messages. Territorial behavior, as defined by the authors, includes all acts that are restricted to a particular area and are crucial for successful reproduction. In the Mongolian gerbil, and probably in other mammals as well, territoriality is controlled by sex hormones acting on specific areas of the central nervous system. Hormones from the gonads apparently act in the brain by altering the genetic apparatus controlling biochemicals used in neural communication. Without these hormones, the animal is socially inert and unable to transmit genes to the next generation. The authors conclude from the results of over ten years of investigation that the most complex social interactions depend on the integrity of the hormone system and its constant tuning by olfactory stimuli. The book incorporates a review of all previously known studies of gerbil behavior and representative data for many other scent-marking species. A stereotaxic brain atlas for the gerbil is a feature that will be especially helpful to other researchers. The book's eclectic nature should make it valuable to anyone concerned with territorial behavior, hormones and behavior, or brain processes, as well as to those who are specifically interested in the Mongolian gerbil.

The evolution of high-crowned teeth, hypsodonty, is a defining characteristic of many terrestrial herbivores. To date, the most prominent focus in the study of the teeth of grazing herbivores has been co-evolution with grasses and grasslands. This book develops the idea further and looks at the myriad ways that soil can enter the diet. Madden then expands this analysis to examine the earth surface processes that mobilize sediment in the environment. The text delivers a global perspective on tooth wear and soil erosion, with examples from the islands of New Zealand to the South American Andes, highlighting how similar geological processes worldwide result in convergent evolution. The final chapter includes a review of elodonty in the fossil record and its environmental consequences. Offering new insights into geomorphology and adaptive and evolutionary morphology, this text will be of value to any researcher interested in the evolution of tooth size and shape.

This book by the renowned naturalist and writer Paul A. Johnsgard tells the complex biological and environmental story of the western Great Plains under the black-tailed prairie dog's reign-and then under a brief but devastating century of human dominion. An introduction to the ecosystem of the shortgrass prairie, Prairie Dog Empire describes in clear and detailed terms the habitat and habits of black-tailed prairie dogs; their subsistence, seasonal behavior, and the makeup of their vast colonies; and the ways in which their "towns" transform the surrounding terrain-for better or for worse. Johnsgard recounts how this terrain has in turn been transformed over the past century by the destruction of prairie dogs and their grassland habitats. This book also offers a rare and invaluable close-up view of the rich history and threatened future of the creature once considered the "keystone" species of the western plains. Included are maps, drawings, and listings of more than two hundred natural grassland preserves where many of the region's native plants and animals may still be seen and studied.

Mammals first evolved at about the same time as dinosaurs, and their story is perhaps the more fascinating of the two - in part because it is also our own story. In this literate and entertaining book, eminent naturalist David Rains Wallace brings the saga of ancient mammals to a general audience for the first time. Using artist Rudolph Zallinger's majestic The Age of Mammals mural at the Peabody Museum as a frame for his narrative, Wallace deftly moves over varied terrain - drawing from history, science, evolutionary theory, and art history - to present a lively account of fossil discoveries and an overview of what those discoveries have revealed about early mammals and their evolution. In these pages we encounter towering mammoths, tiny horses, giant-clawed ground sloths, whales with legs, uintatheres, zhelestids, and other exotic extinct creatures as well as the scientists who discovered and wondered about their remains. We meet such memorable figures as Georges Cuvier, Richard Owen, Edward D. Cope, George Gaylord Simpson, and Stephen Jay Gould and learn of their heated disputes, from Cuvier's and Owen's fights with early evolutionists to present controversies over the Late Cretaceous mass extinction. Wallace's own lifelong interest in evolution is reflected in the book's evocative and engaging style and in the personal experiences he expertly weaves into the tale, providing an altogether expansive perspective on what Darwin described as the 'grandeur' of evolution.

The second installment in a planned three-volume series, this book provides the first substantive review of South American rodents published in over fifty years. Increases in the reach of field research and the variety of field survey methods, the introduction of bioinformatics, and the explosion of molecular-based genetic methodologies have all contributed to the revision of many phylogenetic relationships and to a doubling of the recognized diversity of South American rodents. The largest and most diverse mammalian order on Earth-and an increasingly threatened one-Rodentia is also of great ecological importance, and Rodents is both a timely and exhaustive reference on these ubiquitous creatures. From spiny mice and guinea pigs to the oversized capybara, this book covers all native rodents of South America, the continental islands of Trinidad and Tobago, and the Caribbean Netherlands off the Venezuelan coast. It includes identification keys and descriptions of all genera and species; comments on distribution; maps of localities; discussions of subspecies; and summaries of natural, taxonomic, and nomenclatural history. Rodents also contains a detailed list of cited literature and a separate gazetteer based on confirmed identifications from museum vouchers and the published literature.

'ENCHANTING' MAIL ON SUNDAY They care for their elderly, play with their kids, and always put family first. Can we all learn something from the wisdom of wolves? In this unforgettable book, wolf expert and naturalist Elli Radinger draws on her 25 years of first-hand experience among the wolves of Yellowstone National Park to tell us their remarkable stories. __________ Wolves are more human than we ever knew . . . In fact, they can teach us how to be better humans. They play, love, care for others, show compassion, die of broken hearts, pine for home, work in teams, are endlessly patient and leaders know when to defer to followers. In The Wisdom of Wolves naturalist Elli Radinger takes us on a journey into the heart of the wolf pack, revealing what they can teach us about family, cooperation, survival, leadership, commitment and how to enjoy what life gives us. No other book will bring you closer to discovering the truth about wolves - and ourselves. 'This book is the result of her two decades of close observation; part impassioned memoir, part natural history study, and part photo gallery. Her access to her subjects is extraordinary' SUNDAY TIMES 'Elli's bestselling book suggests that in a high-tech age, when so many of us have become alienated from nature, wolves have much to teach us about the art of living well' DAILY MAIL 'Through The Wisdom of Wolves, we get to feel that little bit closer to the pack and discover what we may have in common' BBC WILDLIFE

The vast terrain between Panama and Tierra del Fuego contains some of the world's richest mammalian fauna, but until now it has lacked a comprehensive systematic reference to the identification, distribution, and taxonomy of its mammals. The first such book of its kind and the inaugural volume in a three-part series, "Mammals of South America" both summarizes existing information and encourages further research of the mammals indigenous to the region. Containing identification keys and brief descriptions of each order, family, and genus, the first volume of "Mammals of South America" covers marsupials, shrews, armadillos, sloths, anteaters, and bats. Species accounts include taxonomic descriptions, synonymies, keys to identification, distributions with maps and a gazetteer of marginal localities, lists of recognized subspecies, brief summaries of natural history information, and discussions of issues related to taxonomic interpretations. Highly anticipated and much needed, this book will be a landmark contribution to mammalogy, zoology, tropical biology, and conservation biology.

In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In "Bat Ecology," world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research.
The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals.
"Bat Ecology" is the most comprehensive state-of-the-field collection for scientists and researchers.

Easy-to-read range maps, detailed anatomical illustrations of different mammals, track illustrations, and a state-by-state location guide make this the decisive authority on North American mammals.

Treeshrews suffer from chronic mistaken identity: they are not shrews, and most are not found in trees. These squirrel-sized, brownish mammals with large, dark, lashless eyes were at one time thought to be primates. Even though most scientists now believe them to belong in their own mammalian order, Scandentia, they still are thought to resemble some of the earliest mammals, which lived alongside the dinosaurs. This book describes the results of the first comparative study of the ecology of treeshrews in the wild. Noted tropical mammalogist Louise H. Emmons conducted this pathbreaking study in the rainforests of Borneo as she tracked and observed six species of treeshrews. Emmons meticulously describes their habitat, diet, nesting habits, home range, activity patterns, social behavior, and many other facets of their lives. She also discusses a particularly interesting aspect of treeshrews: their enigmatic parental care system, which is unique among mammals.
