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.
This remarkable medical parallel launched Natterson-Horowitz on a journey of discovery that reshaped her entire approach to medicine. She began to search for other connections between the human and animal worlds: Do animals get breast cancer, anxiety-induced fainting spells, sexually transmitted diseases? Do they suffer from obsessive-compulsive disorder, bulimia, addiction?
The answers were astonishing. Dinosaurs suffered from brain cancer. Koalas catch chlamydia. Reindeer seek narcotic escape in hallucinogenic mushrooms. Stallions self-mutilate. Gorillas experience clinical depression.
Joining forces with science journalist Kathryn Bowers, Natterson-Horowitz employs fascinating case studies and meticulous scholarship to present a revelatory understanding of what animals can teach us about the human body and mind. “Zoobiquity” is the term the authors have coined to refer to a new, species-spanning approach to health. Delving into evolution, anthropology, sociology, biology, veterinary science, and zoology, they break down the walls between disciplines, redefining the boundaries of medicine.
Zoobiquity explores how animal and human commonality can be used to diagnose, treat, and heal patients of all species. Both authoritative and accessible, offering cutting-edge research through captivating narratives, this provocative book encourages us to see our essential connection to all living beings.
"Estabrook, a reporter of iron constitution and persistence, has dug deep into the truth about the American pork industry without losing his sense of humor and humanity." —Christopher Kimball, Wall Street Journal
In Pig Tales, New York Times best-selling author of Tomatoland Barry Estabrook turns his attention to the dark side of the American pork industry. Drawing on personal experiences raising pigs as well as sharp investigative instincts, Estabrook covers the range of the human-porcine experience. He shows how these intelligent creatures are all too often subjected to lives of suffering in confinement and squalor, sustained on a drug-laced diet just long enough to reach slaughter weight. But Estabrook also reveals how it is possible to raise pigs responsibly and respectfully, benefiting producers and consumers—as well as some of the top chefs in America.
Provocative, witty, and deeply informed, Pig Tales is bound to spark conversation at dinner tables across America.
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.
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.
Intelligent, majestic, and loyal, with lifespans matching our own, elephants are among the greatest of the wonders gracing the African wilds. Yet, in the 1970s and 1980s, about a thousand of these captivating creatures were slaughtered in Zambia each year, killed for their valuable ivory tusks. When biologists Mark and Delia Owens, residing in Africa to study lions, found themselves in the middle of a poaching fray, they took the only side they morally could: that of the elephants.
The Eye of the Elephant recounts the Owens’ struggle to save these innocent animals from decimation, a journey not only to supply the natives with ways of supporting their villages, but also to cultivate support around the globe for the protection of elephants. Filled with daring exploits among disgruntled hunters, arduous labor on the African plains, and vivid depictions of various wildlife, this remarkable tale is at once an adventure story, a travelogue, a preservationist call to action, and a fascinating examination of both human and animal nature.
In 1976 a deadly virus emerged from the Congo forest. As swiftly as it came, it disappeared, leaving no trace. Over the four decades since, Ebola has emerged sporadically, each time to devastating effect. It can kill up to 90 percent of its victims. In between these outbreaks, it is untraceable, hiding deep in the jungle. The search is on to find Ebola’s elusive host animal. And until we find it, Ebola will continue to strike. Acclaimed science writer and explorer David Quammen first came near the virus while he was traveling in the jungles of Gabon, accompanied by local men whose village had been devastated by a recent outbreak. Here he tells the story of Ebola—its past, present, and its unknowable future.
Extracted from Spillover by David Quammen, updated and with additional material.

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.
Left in the wild, Billie the elephant would have spent her days surrounded by family, free to wander the jungles of Asia. Instead, traders captured her as a baby and shipped her to America, where she learned to carry humans, stand on a tub and balance on one leg – the full repertoire of elephant tricks. For decades, Billie crisscrossed the country, dazzling audiences as she performed breathtaking stunts. But behind the scenes she lived a life of misery: traveling in trucks, chained for hours on end, barely able to move, giving eight-minute performances under harsh lights and to the sounds of blaring music. And worse.Finally, she got a lucky break. As part of the largest elephant rescue in American history, Billie wound up at a sanctuary for performing elephants in Tennessee, able once more to roam through open meadows and share her days with a herd. She would never be beaten again. But, overcome with anxiety, she withdrew from the rest of the elephants and refused to let anyone remove a chain still clamped around her leg. Her caregivers began to wonder if Billie could ever escape her emotional wounds. The compelling story of Billie's battle to reclaim her old self is a testament to the intelligence, emotional complexity and remarkable strength of all elephants, captive or free.
In this edition, more than three-quarters of the text is new, and information from more than seventy-five contributors is thoroughly updated.

At long last, dogs will know just how smart their owners can be. By unlocking the secrets of the hidden language of dogs, psychologist Stanley Coren allows us into the doggy dialogue, or "Doggish," and makes effective
communication a reality.
Drawing on substantial research in animal behavior, evolutionary biology, and years of personal experience, Coren demonstrates that the average house dog can understand language at about the level of a two-year-old human. While actual conversation of the sort Lassie seemed capable of in Hollywood mythmaking remains forever out of reach, Coren shows us that a great deal of real communication is possible beyond the giving and obeying of commands.
How to Speak Dog not only provides the sounds, words, actions, and move-ments with which we can effectively communicate with our dogs, but also deciphers the signs that our dogs give to us. With easy-to-follow tips on how humans can mimic the language dogs use to talk with one another, original drawings illustrating the subtleties of their body language, and a handy visual glossary and "Doggish" phrasebook, How to Speak Dog gives dog lovers the skills they need to improve their relationships with their pets.

The Instant #1 International Bestseller
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.
Bob Norris is a cowboy with an enormous empathy for animals that overwhelms his other emotions. He was raised with a pet bear and as a boy decided to become a real cowboy. He saw his dream come true in Colorado on one of the larger horse-and-cattle ranches in America. Handsome as a movie star, he became the Marlboro Man and appeared on TV and on billboards around the world. But with the passing of years, and with his own family grown up, he felt the need for something that he could not name.
When she came into his life by happenstance, the hurt, vulnerable little elephant tapped the fullness of Bob's empathy, and an incredible bond between the most unlikely of friends was forged.
Bob adopted the baby orphan elephant--named Amy--and patiently set about helping her recover from the trauma of her ordeal. He had never seen a real African elephant up close, except in zoos. He was a horseman and breeder of champion quarter horses. But through close observation, gentle training, humor, and endless perseverance, Bob gradually coaxed Amy into overcoming her mistrust of humans, and indeed, her fear of the world. The little elephant became a "hand" on Bob's ranch, tending to simple chores, riding the fences, and shadowing Bob on his horse. She developed a winning personality, and a strong character, and became a beloved member of the Norris family and partner to the ranch hands.
But Bob knew from the start that the ultimate goal was for Amy to regain her confidence and her independence - even, if it were possible, to go back to the savannahs of Africa.
This is the true story of how Amy and Bob came together. No one who reads The Cowboy and His Elephant can fail to be moved by such a simple tale of unlikely love.
Due to the intense curiosity of one groundbreaking deer, and the resulting introduction to an entire herd, Joe Hutto has been allowed unprecedented access and insight into the minds and behavior of this special animal.

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.
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.

Organized into 10 chapters, this volume begins with a historical overview of bat origins and evolution, karyotypic trends in bats, and the role of karyotypes in studying the biology of bats. It then discusses the bat skeletal and muscular systems; flight patterns and aerodynamics; prenatal and postnatal development; migration and homing; ecology and physiological ecology of bat hibernation; thermoregulation and metabolism; and the urinary system, including gross anatomy and embryology, histophysiology, and renal physiology. It also looks at morphological contrasts between the skulls and dentitions of different families and genera of bats.
This book will benefit biologists, zoologists, teachers, and others concerned with the general biology of Chiroptera.
The secretion and physiology of chorionic somatomammotropin in primates; the placental thyroid stimulators and thyroid function in pregnancy; and growth factors in fetal growth and development are also considered. The book further tackles the production and activity of placental releasing hormone; the endocrinology of parturition; and sex-determining genes and gene regulation. The text also looks into the testicular hormone production in fetal rhesus macaque; the control of pituitary gonadotropin secretion in fetal rhesus macaque; and the development of the regulatory mechanisms of the hypothalamic-pituitary-gonadal system in the human fetus. The development of the fetal adrenals in nonhuman primates and perspectives in fetal endocrinology are also encompassed. Reproductive physiologists, pediatricians, gynecologists, and endocrinologists will find the book invaluable.
The first five chapters cover different kinds of electrical stimulation, their basic principles, and techniques involved. These include extracellular and intracellular stimulation, the microstimulation technique, and the stimulation of the brain. Chapters 6 to 9 discuss the beneficial effects and uses of these stimulation techniques, such as motivation and reinforcement, memory research, its relation to brain lesions, and the implications for electroconvulsive therapy. The last two chapters talk about the electrical stimulation of the peripheral nerve and the grid and peripheral shock stimulation.
The book is recommended for psychotherapists who wish to learn more about the use of electrical stimulation techniques as treatment, and for neurologists who would like to further understand the effects of electrical stimulation.
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.
