In Cat Sense, renowned anthrozoologist John Bradshaw takes us further into the mind of the domestic cat than ever before, using cutting-edge scientific research to dispel the myths and explain the true nature of our feline friends. Tracing the cat's evolution from lone predator to domesticated companion, Bradshaw shows that although cats and humans have been living together for at least eight thousand years, cats remain independent, predatory, and wary of contact with their own kind, qualities that often clash with our modern lifestyles. Cats still have three out of four paws firmly planted in the wild, and within only a few generations can easily revert back to the independent way of life that was the exclusive preserve of their predecessors some 10,000 years ago. Cats are astonishingly flexible, and given the right environment they can adapt to a life of domesticity with their owners-but to continue do so, they will increasingly need our help. If we're to live in harmony with our cats, Bradshaw explains, we first need to understand their inherited quirks: understanding their body language, keeping their environments-however small-sufficiently interesting, and becoming more proactive in managing both their natural hunting instincts and their relationships with other cats.
A must-read for any cat lover, Cat Sense offers humane, penetrating insights about the domestic cat that challenge our most basic assumptions and promise to dramatically improve our pets' lives-and ours.
The volume contains 36 contributions presented during the seven sessions of the conference. The papers presented in Session I examined T-cell tolerance. The presentations in Session II focused on B cell tolerance. The papers in Sessions III and IV focused on the mechanisms of B cell and T cell tolerance, respectively. Session V dealt with the activity of suppressor cells as a mechanism of tolerance. The papers in Session VI investigated the suppressive activity of antibody and antigen-antibody complexes. In Session VII a final General Discussion was held in order to identify what has been established concerning the phenomenology and mechanisms of specific immunological tolerance, what are the major unresolved issues, and what approaches appear most promising to answer these questions.
When Bronwen Dickey brought her new dog home, she saw no traces of the infamous viciousness in her affectionate, timid pit bull. Which made her wonder: How had the breed—beloved by Teddy Roosevelt, Helen Keller, and Hollywood’s “Little Rascals”—come to be known as a brutal fighter?
Her search for answers takes her from nineteenth-century New York City dogfighting pits—the cruelty of which drew the attention of the recently formed ASPCA—to early twentieth‑century movie sets, where pit bulls cavorted with Fatty Arbuckle and Buster Keaton; from the battlefields of Gettysburg and the Marne, where pit bulls earned presidential recognition, to desolate urban neighborhoods where the dogs were loved, prized—and sometimes brutalized.
Whether through love or fear, hatred or devotion, humans are bound to the history of the pit bull. With unfailing thoughtfulness, compassion, and a firm grasp of scientific fact, Dickey offers us a clear-eyed portrait of this extraordinary breed, and an insightful view of Americans’ relationship with their dogs.

How do cats know when it's time to go to the vet, even before the cat carrier comes out? How do dogs know when their owners are returning home at unexpected times? How can horses find their way back to the stable over completely unfamiliar terrain?
After five years of extensive research involving thousands of people who have pets and work with animals, Dr. Sheldrake proves conclusively what many pet owners already know: there is a strong connection between humans and animals that defies present-day scientific understanding. Sheldrake compellingly demonstrates that we and our pets are social animals linked together by invisible bonds connecting animals to each other, to their owners, and to their homes in powerful ways. His provocative ideas about these social, or morphic, fields explain the uncanny behavior often observed in pets and help provide an explanation for amazing animal behavior in the wild, such as migration and homing.
Dogs That Know When Their Owners Are Coming Home not only provides fascinating insight into animal, and human, behavior, but also teaches us to question the boundaries of conventional scientific thought, and shows that the very animals who are closest to us have much to teach us about biology, nature, and consciousness.

Some people's lives are entirely their own creations. James Rebanks' isn't. The first son of a shepherd, who was the first son of a shepherd himself, his family have lived and worked in the Lake District of Northern England for generations, further back than recorded history. It's a part of the world known mainly for its romantic descriptions by Wordsworth and the much loved illustrated children's books of Beatrix Potter. But James' world is quite different. His way of life is ordered by the seasons and the work they demand. It hasn't changed for hundreds of years: sending the sheep to the fells in the summer and making the hay; the autumn fairs where the flocks are replenished; the grueling toil of winter when the sheep must be kept alive, and the light-headedness that comes with spring, as the lambs are born and the sheep get ready to return to the hills and valleys.
The Shepherd's Life the story of a deep-rooted attachment to place, modern dispatches from an ancient landscape that describe a way of life that is little noticed and yet has profoundly shaped the landscape over time. In evocative and lucid prose, James Rebanks takes us through a shepherd's year, offering a unique account of rural life and a fundamental connection with the land that most of us have lost. It is a story of working lives, the people around him, his childhood, his parents and grandparents, a people who exist and endure even as the culture - of the Lake District, and of farming - changes around them.
Many memoirs are of people working desperately hard to leave a place. This is the story of someone trying desperately hard to stay.
Animals Make Us Human is the culmination of almost thirty years of research, experimentation, and experience. This is essential reading for anyone who’s ever owned, cared for, or simply cared about an animal.
Europeans reached North American with their attitudes already formed. The wilderness pressed in upon their tiny settlements in constant threat and all energies were devoted to destroying it and turning its inexhaustible resources to use. Over vast areas of the continent the wolf went down with the wilderness before the unprecedented effectiveness of our technological attack on the ecology of a continent.
Today, however, there is a great tide of concern over the consequences of our assault on the wild lands and wild creatures on the continent, and more and more biologists are devoting their knowledge and energy to searching studies of our land and its native biota.
The wolf has been the subject of detailed study by a number of ecologists on this continent who make use of all the research devices now available. Much of our knowledge is very recent, is increasing rapidly, and has resulted from the work of a mere handful of keen, resourceful, and courageous students of wolf biology. This, the first book to attempt a complete account of the biology of the wolf, draws from years of field research and upon the rich literature from two continents.
--From the foreword by Ian McTaggert Cowan
Expelled from Botswana for writing Cry of the Kalahari, the Owenses set off across Africa. They settled in Zambia, where they soon found their peace shattered by the gunfire of elephant poachers. This is the story of the couple's battle to save the elephants and their own lives.
Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal.
Drawing on their own research as well as a scientific literature as immense as the sea—including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience—Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.
There are close to 5,500 species in the class Mammalia, including the blue whale—the largest animal that has ever lived—and the pygmy shrew, which weighs little more than a penny. The functional diversity of mammals has allowed them to play critical roles in every ecosystem, whether marine, freshwater, alpine, tundra, forest, or desert.
Many mammal species are critically endangered and present complex conservation and management challenges. This book touches on those challenges, which are often precipitated by overharvesting and habitat loss, as well as emerging threats, such as the impact of wind turbines and white nose syndrome on bats and chronic wasting disease on deer.
Among the updates and additions to the fourth edition of Mammalogy are numerous new photos, figures, and cladograms, over 4,200 references, as well as
• A completely new chapter on mammalian phylogeny and genomics• Current taxonomy—including major changes to orders, suborders, and superfamilies of bats and rodents• An explanation of the recent inclusion of whales with terrestrial even-toed ungulates• Updates on mammalian structural, functional adaptations, and fossil history• recent advances in our understanding of phylogeny, biogeography, social behavior, and ecology• A discussion of two new orders and thirteen newly recognized extant families • Reflections on the implications of climate change for mammals• Thorough examinations of several recently described species, including Durrell’s vontsira ( Salanoia durrelli) and the Laotian rock rat ( Laonastes aenigmamus)• An explanation of mammalian biomechanics, such as that seen in lunge feeding of baleen whales• Breakout boxes on unique aspects of mammals, including the syntax of bat songs, singing mice, and why there are no green mammals (unless we count algae-covered sloths) Maintaining the accessible, readable style for which Feldhamer and his coauthors are well known, this new edition of Mammalogy is the authoritative textbook on this amazingly diverse class of vertebrates.
A wide variety of bat species live in the United States and Canada, ranging from the California leaf-nosed bat to the Florida bonneted bat, from the eastern small-footed bat to the northern long-eared bat. The authors provide an overview of bat classification, biology, feeding behavior, habitats, migration, and reproduction. They discuss the ever-increasing danger bats face from destruction of habitat, wind turbines, chemical toxicants, and devastating diseases like white-nose syndrome, which is killing millions of cave bats in North America. Illustrated species accounts include range maps and useful identification tips.
Written by three of the world’s leading bat experts and featuring J. Scott Altenbach's stunning photographs, this fact-filled and easy-to-use book is the most comprehensive and up-to-date account of bats in the U.S. and Canada.
Echols joins his vast knowledge of biology with personal interviews of the principal operators and promoters in the field to convey a captivating side of science--specifically, how the personalities of scientists and their competitive and collaborative relations affect new ideas and discoveries. The author reveals how logic and order often arise only in hindsight from the chaos of discovery; eventual solutions often come from experiments performed for entirely different reasons. Echols also shares his deep-seated feelings for the science itself, communicating his admiration, even awe, for the purity and simplicity with which life systems are organized. This gripping insider's account of the first fifty years of molecular biology ties together the biological questions with the scientific solutions of the people who established the field. It will appeal not only to students and those interested in the development of the discipline, but to anyone intrigued by the human side of science and the process of scientific inquiry and discovery.
In this edition, more than three-quarters of the text is new, and information from more than seventy-five contributors is thoroughly updated. The standard text for all courses in zoo biology, Wild Mammals in Captivity will, in its new incarnation, continue to be used by zoo managers, animal caretakers, researchers, and anyone with an interest in how to manage animals in captive conditions.
In this popularly written book, three long-time observers of the okapi present a complete, contemporary natural history of this appealing relative of the giraffe. They recount its discovery by European explorers and describe its appearance and life cycle. They also discuss current efforts to preserve the species, both in the wild and at zoos around the world.
Illustrated with charming line drawings, The Okapi will be a valuable resource for conservationists and zoo visitors alike-indeed anyone fascinated by the mysterious animal of Congo-Zaire.
From bobcats to servals, small cats are spread across the globe. They range in size from the rusty-spotted cat and African black-footed cat, each of which weighs around 5 pounds when fully grown, to the Eurasian lynx, which can reach an adult weight of 60 pounds. These felids are elusive, some are nocturnal, others are arboreal, and all are rare and secretive, making them especially difficult to study. James G. Sanderson, the world’s leading field expert on small wild cats, and naturalist and wildlife artist Patrick Watson provide informative and entertaining answers to common and unexpected questions about these animals. The authors explain why some small cats live on the ground while others inhabit trees, discuss the form and function of their coat types and colors, offer scientifically sound information on human–small wild cat interactions, and even review the role that small wild cats have played in literature, religion, and mythology.
The world of cats is as fascinating as it is diverse. Small Wild Cats: The Animal Answer Guide shows just how important and interesting the littlest of the nondomesticated feline family are.

“This is an important book, not just for its valuable information on lions, but for its broad, open, and intelligent approach to problems that cut across the fields of behavior, populations, ecology, wildlife management, evolution, anthropology, and comparative biology.”—Richard G. Van Gelder, Bioscience
Amanda Owen has been seen by millions on ITV's The Dales, living a life that has almost gone in today's modern world, a life ruled by the seasons and her animals. She is a farmer's wife and shepherdess, living alongside her husband Clive and seven children at Ravenseat, a 2000 acre sheep hill farm at the head of Swaledale in North Yorkshire. It's a challenging life but one she loves.
In The Yorkshire Shepherdess she describes how the rebellious girl from Huddersfield, who always wanted to be a shepherdess, achieved her dreams. Full of amusing anecdotes and unforgettable characters, the book takes us from fitting in with the locals to fitting in motherhood, from the demands of the livestock to the demands of raising a large family in such a rural backwater. Amanda also evokes the peace of winter, when they can be cut off by snow without electricity or running water, the happiness of spring and the lambing season, and the backbreaking tasks of summertime - haymaking and sheepshearing - inspiring us all to look at the countryside and those who work there with new appreciation.
–from The Good Good Pig
A naturalist who spent months at a time living on her own among wild creatures in remote jungles, Sy Montgomery had always felt more comfortable with animals than with people. So she gladly opened her heart to a sick piglet who had been crowded away from nourishing meals by his stronger siblings. Yet Sy had no inkling that this piglet, later named Christopher Hogwood, would not only survive but flourish–and she soon found herself engaged with her small-town community in ways she had never dreamed possible. Unexpectedly, Christopher provided this peripatetic traveler with something she had sought all her life: an anchor (eventually weighing 750 pounds) to family and home.
The Good Good Pig celebrates Christopher Hogwood in all his glory, from his inauspicious infancy to hog heaven in rural New Hampshire, where his boundless zest for life and his large, loving heart made him absolute monarch over a (mostly) peaceable kingdom. At first, his domain included only Sy’s cosseted hens and her beautiful border collie, Tess. Then the neighbors began fetching Christopher home from his unauthorized jaunts, the little girls next door started giving him warm, soapy baths, and the villagers brought him delicious leftovers. His intelligence and fame increased along with his girth. He was featured in USA Today and on several National Public Radio environmental programs. On election day, some voters even wrote in Christopher’s name on their ballots.
But as this enchanting book describes, Christopher Hogwood’s influence extended far beyond celebrity; for he was, as a friend said, a great big Buddha master. Sy reveals what she and others learned from this generous soul who just so happened to be a pig–lessons about self-acceptance, the meaning of family, the value of community, and the pleasures of the sweet green Earth. The Good Good Pig provides proof that with love, almost anything is possible.

The real story of AIDS—how it originated with a virus in a chimpanzee, jumped to one human, and then infected more than 60 million people—is very different from what most of us think we know. Recent research has revealed dark surprises and yielded a radically new scenario of how AIDS began and spread. Excerpted and adapted from the book Spillover, with a new introduction by the author, Quammen's hair-raising investigation tracks the virus from chimp populations in the jungles of southeastern Cameroon to laboratories across the globe, as he unravels the mysteries of when, where, and under what circumstances such a consequential "spillover" can happen. An audacious search for answers amid more than a century of data, The Chimp and the River tells the haunting tale of one of the most devastating pandemics of our time.
First a regimental mascot for Canadians training for wartime service, Winnie then became a star attraction at the London Zoo, and ultimately inspired one of the best-loved characters in children's literature.

As in the works of George Schaller and Cynthia Moss, Packer transports us to life in the field. He is addicted to this land—to the beauty of a male lion striding across the Serengeti plains, to the calls of a baboon troop through the rain forests of Gombe—and to understanding the animals that inhabit it. Through his vivid narration, we feel the dust and the bumps of the Arusha Road, smell the rosemary in the air at lunchtime on a Serengeti verandah, and hear the lyrics of the Grateful Dead playing off bootlegged tapes.
Into Africa also explores the social lives of the animals and the threats to their survival. Packer grapples with questions he has passionately tried to answer for more than two decades. Why do female lions raise their young in crèches? Why do male baboons move from troop to troop while male chimps band together? How can humans and animals continue to coexist in a world of diminishing resources? Immediate demands—logistical nightmares, political upheavals, physical exhaustion—yield to the larger inescapable issues of the interdependence of the land, the animals, and the people who inhabit it.

From as far back in time as the disappearance of the dinosaurs, cats have occupied an important place in our evolutionary, social, and cultural history. The family of the cat is as diverse as it is widespread, ranging from the lions, tigers, and pumas of the African and Asian wilds to the domesticated cats of our homes, zoos, and circuses.
When she witnesses her housecat, Rajah, effortlessly scare off two fully-grown deer, acclaimed anthropologist Elizabeth Marshall Thomas starts studying the links that bind the feline family together. Immersing herself in the subtle differences of their social orders, feeding behaviors, and means of communication, Thomas explores the nature of the cat, both wild and domestic, and the resilient streak that has ensured its survival over thousands of years.
In Elephant Don, O’Connell, one of the leading experts on elephant communication and social behavior, offers a rare inside look at the social world of African male elephants. Elephant Don tracks Greg and his group of bulls as O’Connell tries to understand the vicissitudes of male friendship, power struggles, and play. A frequently heart-wrenching portrayal of commitment, loyalty, and affection between individuals yearning for companionship, it vividly captures an incredible repertoire of elephant behavior and communication. Greg, O’Connell shows, is sometimes a tyrant and other times a benevolent dictator as he attempts to hold onto his position at the top. Though Elephant Don is Greg’s story, it is also the story of O’Connell and the challenges and triumphs of field research in environs more hospitable to lions and snakes than scientists.
Readers will be drawn into dramatic tales of an elephant society at once exotic and surprisingly familiar, as O’Connell’s decades of close research reveal extraordinary discoveries about a male society not wholly unlike our own. Surely we’ve all known a Greg or two, and through this book we may come to know them in a whole new light.
Island Bats is the first book to focus solely on the evolution, ecology, and conservation of bats living in the world’s island ecosystems. Among other topics, the contributors to this volume examine how the earth’s history has affected the evolution of island bats, investigate how bat populations are affected by volcanic eruptions and hurricanes, and explore the threat of extinction from human disturbance. Geographically diverse, the volume includes studies of the islands of the Caribbean, the Western Indian Ocean, Micronesia, Indonesia, the Philippines, and New Zealand.
With its wealth of information from long-term studies, Island Bats provides timely and valuable information about how this fauna has evolved and how it can be conserved.

Introductory sections contain practical advice on all elements of rearing calves and keeping cattle, including what to consider about land, housing and fencing, whether to choose beef or dairy cows, tips on buying, moving and handling your stock, and guidance on feeding and breeding.
As historian Mark Essig reveals in Lesser Beasts, swine have such a bad reputation for precisely the same reasons they are so valuable as a source of food: they are intelligent, self-sufficient, and omnivorous. What’s more, he argues, we ignore our historic partnership with these astonishing animals at our peril. Tracing the interplay of pig biology and human culture from Neolithic villages 10,000 years ago to modern industrial farms, Essig blends culinary and natural history to demonstrate the vast importance of the pig and the tragedy of its modern treatment at the hands of humans. Pork, Essig explains, has long been a staple of the human diet, prized in societies from Ancient Rome to dynastic China to the contemporary American South. Yet pigs’ ability to track down and eat a wide range of substances (some of them distinctly unpalatable to humans) and convert them into edible meat has also led people throughout history to demonize the entire species as craven and unclean. Today’s unconscionable system of factory farming, Essig explains, is only the latest instance of humans taking pigs for granted, and the most recent evidence of how both pigs and people suffer when our symbiotic relationship falls out of balance.
An expansive, illuminating history of one of our most vital yet unsung food animals, Lesser Beasts turns a spotlight on the humble creature that, perhaps more than any other, has been a mainstay of civilization since its very beginnings—whether we like it or not.
Brolga has been rescuing these special creatures for years, slowly and painstakingly creating a kangaroo sanctuary for the many kangaroos he has saved, reared and loved.
He has dedicated his life to observing how kangaroo mums care for their babies and does everything he can to replicate this. The baby kangaroos, traumatised by losing their mother so early, are tucked up into pillow cases and kept warm and comforted next to Brolga at night. We see him getting up at 4am to bottle feed them, washing them in a little tub, taking them to the supermarket and generally mothering them with heart breaking tenderness.
Charting Brolga's life with the joeys and honing in on his relationship with one or two in particular, Kangaroo Dundee tells the heart-warming, sometimes funny, sometimes poignant story of one man's unique relationship with a group of extraordinary animals.
When John Fowles reviewed Of Wolves and Men, he called it “A remarkable book, both biologically absorbing and humanly rich, and one that should be read by every concerned American.” In this National Book Award–shortlisted work, literary master Barry Lopez guides us through the world of the wolf and our often-mistaken perceptions of another species’ place on our shared planet. Throughout the centuries, the wolf has been a figure of fascination and mystery, and a major motif in literature and myth. Inspiring fear and respect, the creature has long exerted a powerful influence on the human imagination. Of Wolves and Men takes the reader into the world of the Canis lupus and its relationship to humankind through the ages. Lopez draws on science, history, mythology, and his own field research to present a compelling portrait of wolves both real and imagined, dispelling our fear of them while celebrating their place in our history, legends, and hearts. This ebook features an illustrated biography of Barry Lopez including rare images and never-before-seen documents from the author’s personal collection.
In 1984, Alexandra moved to a remote bay in British Columbia to continue her research with wild orcas.

In Pig, Brett Mizelle provides a richly illustrated and compelling look at the long, complicated relationship between humans and these highly intelligent, sociable animals. Mizelle traces the natural and cultural history of the pig, focusing on the contradictions between our imaginative representation of pigs and the real-world truth of the ways in which pigs are prized for their meat, used as subjects in medical research, and killed in order to make hundreds of consumer products. Pig begins with the evolution of the suidae, animals that were domesticated in multiple regions 9,000 years ago, and points toward a future where pigs and humans are even more closely intertwined as a result of biomedical breakthroughs. Pig both examines the widespread art, entertainment, and literature that imagines human kinship with pigs and the development of modern industrial pork production.
In charting how humans have shaped the pig and how the pig has shaped us, Mizelle focuses on the unresolved contradictions between the fiction and the reality of our relations with pigs.
An attractive backpack-size volume, written in lively prose, the Guide to the Mammals of Pennsylvania opens with a short introduction to Pennsylvania's environment and the characteristics defining a mammal. The bulk of the book consists of species accounts of the mammals grouped into families and orders. Each account includes a short list of data, a Pennsylvania range map, a North American range map, and a narrative of the physical, ecological, and behavioral characteristics of the species.
Exciting photographs of each of the species in its natural habitat, 17 in color, and drawings of animal tracks are especially useful for identification, and a glossary and a bibliography provide definitions and references for the serious reader. Naturalists, whether amateur or professional, will find the book useful in the field; it will be an indispensable tool in the classroom.
