Part One explores lizard lifestyles, answering such questions as why lizards are active when they are, why they behave as they do, how they avoid predators, why they eat what they eat, and how they reproduce and socialize. In Part Two the authors take us on a fascinating tour of the world's manifold lizard species, beginning with iguanians, an evolutionary group that includes some of the most bizarre lizards, the true chameleons of Africa and Madagascar. We also meet the glass lizard, able to break its tail into many highly motile pieces to distract a predator from its body; lizards that can run across water; and limbless lizards, such as snakes. Part Three gives an unprecedented global view of evolutionary trends that have shaped present-day lizard communities and considers the impact of humans on their future.

Horowitz introduces the reader to dogs’ perceptual and cognitive abilities and then draws a picture of what it might be like to be a dog. What’s it like to be able to smell not just every bit of open food in the house but also to smell sadness in humans, or even the passage of time? How does a tiny dog manage to play successfully with a Great Dane? What is it like to hear the bodily vibrations of insects or the hum of a fluorescent light? Why must a person on a bicycle be chased? What’s it like to use your mouth as a hand? In short, what is it like for a dog to experience life from two feet off the ground, amidst the smells of the sidewalk, gazing at our ankles or knees?
Inside of a Dog explains these things and much more. The answers can be surprising—once we set aside our natural inclination to anthropomorphize dogs. Inside of a Dog also contains up-to-the-minute research—on dogs’ detection of disease, the secrets of their tails, and their skill at reading our attention—that Horowitz puts into useful context. Although not a formal training guide, Inside of a Dog has practical application for dog lovers interested in understanding why their dogs do what they do. With a light touch and the weight of science behind her, Alexandra Horowitz examines the animal we think we know best but may actually understand the least. This book is as close as you can get to knowing about dogs without being a dog yourself.
Anarchy Evolution is a provocative look at the collision between religion and science, by an author with unique authority: UCLA lecturer in Paleontology, and founding member of Bad Religion, Greg Graffin. Alongside science writer Steve Olson (whose Mapping Human History was a National Book Award finalist) Graffin delivers a powerful discussion sure to strike a chord with readers of Richard Dawkins’ The God Delusion or Christopher Hitchens God Is Not Great. Bad Religion die-hards, newer fans won over during the band’s 30th Anniversary Tour, and anyone interested in this increasingly important debate should check out this treatise on science from the god of punk rock.
The Monks of New Skete have achieved international renown as breeders of German shepherds and as outstanding trainers of dogs of all breeds. Their unique approach to canine training, developed and refined over four decades, is based on the philosophy that "understanding is the key to communication, compassion, and communion" with your dog.
How to Be Your Dog's Best Friend covers virtually every aspect of living with and caring for your dog, including:
Selecting a dog (what breed? male? female? puppy or older dog?) to fit your lifestyle
Where to get--and where not to get--a dog
Reading a pedigree
Training your dog or puppy--when, where, and how
The proper use of praise and discipline
Feeding, grooming, and ensuring your dog's physical fitness
Recognizing and correcting canine behavioral problems
The particular challenges of raising a dog where you live - in the city, country, or suburb
The proper techniques for complete care of your pet at every stage of his or her lifeIn its scope, its clarity, and its authority, How to Be Your Dog's Best Friend remains unrivaled as a basic training guide for dog owners. Like no other book, this guide can help you understand and appreciate your dog's nature as well as his or her distinct personality--and in so doing, it can significantly enrich the life you share with your dog.
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.
As development and subsequent habitat destruction accelerate, there are increasing pressures on wildlife populations. But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity. There is an unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. In many parts of the world, habitat destruction has been so extensive that local wildlife is in crisis and may be headed toward extinction.
Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and the new paperback edition—with an expanded resource section and updated photos—will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.
Hailed as a classic, Are We Smart Enough to Know How Smart Animals Are? explores the oddities and complexities of animal cognition—in crows, dolphins, parrots, sheep, wasps, bats, chimpanzees, and bonobos—to reveal how smart animals really are, and how we’ve underestimated their abilities for too long. Did you know that octopuses use coconut shells as tools, that elephants classify humans by gender and language, and that there is a young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame? Fascinating, entertaining, and deeply informed, de Waal’s landmark work will convince you to rethink everything you thought you knew about animal—and human—intelligence.
If chaos theory transformed our view of the universe, biomimicry is transforming our life on Earth. Biomimicry is innovation inspired by nature – taking advantage of evolution’s 3.8 billion years of R&D since the first bacteria. Biomimics study nature’s best ideas: photosynthesis, brain power, and shells – and adapt them for human use. They are revolutionising how we invent, compute, heal ourselves, harness energy, repair the environment, and feed the world.
Science writer and lecturer Janine Benyus names and explains this phenomenon. She takes us into the lab and out in the field with cutting-edge researchers as they stir vats of proteins to unleash their computing power; analyse how electrons zipping around a leaf cell convert sunlight into fuel in trillionths of a second; discover miracle drugs by watching what chimps eat when they’re sick; study the hardy prairie as a model for low-maintenance agriculture; and more.
"The most scientifically important dog in over a century." —Brian Hare
Chaser has fascinated dog lovers and scientists alike. Her story reveals the potential for taking out dialogue with dogs well beyond "fetch." When retired psychology professor John Pilley first got his new Border collie puppy, Chaser, he wanted to explore the boundaries of language learning and communication between humans and man's best friend. Exhibiting intelligence previously thought impossible in dogs, Chaser soon learned the names of more than a thousand toys and sentences with multiple elements of grammar. Chaser's accomplishments are revolutionizing the way we think about the intelligence of animals. John and Chaser's inspiring journey demonstrates the power of learning through play and opens our eyes to the boundless potential in the animals we love.

From the coasts of Indonesia to the rainforests of Peru, venomous animals are everywhere—and often lurking out of sight. Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.
Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.
Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.
Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.
From Russia to Bengal to Palm Beach, Randall Packard’s far-ranging narrative traces the natural and social forces that help malaria spread and make it deadly. He finds that war, land development, crumbling health systems, and globalization—coupled with climate change and changes in the distribution and flow of water—create conditions in which malaria's carrier mosquitoes thrive. The combination of these forces, Packard contends, makes the tropical regions today a perfect home for the disease.
Authoritative, fascinating, and eye-opening, this short history of malaria concludes with policy recommendations for improving control strategies and saving lives.

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.
Much has been written about global warming, but the crucial relationship between people and ice has received little focus—until now. As one of the world’s leading experts on climate change, Henry Pollack provides an accessible, comprehensive survey of ice as a force of nature, and the potential consequences as we face the possibility of a world without ice.
A World Without Ice traces the effect of mountain glaciers on supplies of drinking water and agricultural irrigation, as well as the current results of melting permafrost and shrinking Arctic sea ice—a situation that has degraded the habitat of numerous animals and sparked an international race for seabed oil and minerals. Catastrophic possibilities loom, including rising sea levels and subsequent flooding of lowlying regions worldwide, and the ultimate displacement of millions of coastal residents. A World Without Ice answers our most urgent questions about this pending crisis, laying out the necessary steps for managing the unavoidable and avoiding the unmanageable.
Paul Hawken has spent more than a decade researching organizations dedicated to restoring the environment and fostering social justice. From billion-dollar nonprofits to single-person dot.causes, these groups collectively comprise the largest movement on earth, a movement that has no name, leader, or location and that has gone largely ignored by politicians and the media.
Blessed Unrest explores the diversity of the movement, its brilliant ideas, innovative strategies, and centuries of hidden history. A culmination of Hawken?s many years of leadership in the environmental and social justice fields, it will inspire all who despair of the world?s fate, and its conclusions will surprise even those within the movement itself.
By venturing out of her clinic and spending time on seven family farms, Miller uncovers all the aspects of farming—from seed choice to soil management—that have a direct and powerful impact on our health. Bridging the traditional divide between agriculture and medicine, Miller shares lessons learned from inspiring farmers and biomedical researchers and artfully weaves their insights and discoveries, along with stories from her patients, into the narrative. The result is a compelling new vision for sustainable healing and a treasure trove of farm-to-body lessons that have immense value in our daily lives.
In Farmacology you will meet:a vegetable farmer in Washington State who shows us how the principles he uses to rejuvenate his soil apply just as well to our own bodies. Here we also discover the direct links between healthy soil and healthy humans. a beef farmer in Missouri who shows how a holistic cattle-grazing method can grow resilient calves and resilient children. an egg farmer in Arkansas who introduces us to the counterintuitive idea that stress can keep us productive and healthy. We discover why the stressors associated with a pasture-based farming system are beneficial to animals and humans while the duress of factory farming can make us ill. a vintner in Sonoma, California, who reveals the principles of Integrated Pest Management and helps us understand how this gentler approach to controlling unwanted bugs and weeds might be used to treat invasive cancers in humans. a farmer in the Bronx who shows us how a network of gardens offers health benefits that extend far beyond the nutrient value of the fruits and vegetables grown in the raised beds. For example, did you know that urban farming can lower the incidence of alcoholism and crime? finally, an aromatic herb farmer in Washington State who teaches us about the secret chemical messages we exchange with plants—messages that can affect our mood and even keep us looking youthful.
In each chapter, Farmacology reveals the surprising ways that the ecology of our body and the ecology of our farms are intimately linked. This is a paradigm-changing adventure that has huge implications for our personal health and the health of the planet.
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

In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.
An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.
Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines
• what salvage logging is and why it is controversial
• natural and human disturbance regimes in forested ecosystems
• differences between salvage harvesting and traditional timber harvesting
• scientifically documented ecological impacts of salvage operations
• the importance of land management objectives in determining appropriate post-disturbance interventions
Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts.
Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.
IMAGINE A WORLD WHERE parasites are masters of chemical warfare and camouflage, able to cloak themselves with their hosts' own molecules.
IMAGINE A WORLD WHERE parasites steer the course of evolution, where the majority of species are parasites.
WELCOME TO EARTH.
For centuries, parasites have lived in nightmares, horror stories, and in the darkest shadows of science. Yet these creatures are among the world's most successful and sophisticated organisms. In Parasite Rex, Carl Zimmer deftly balances the scientific and the disgusting as he takes readers on a fantastic voyage. Traveling from the steamy jungles of Costa Rica to the fetid parasite haven of southern Sudan, Zimmer graphically brings to life how parasites can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead.
This thorough, gracefully written book brings parasites out into the open and uncovers what they can teach us about the most fundamental survival tactics in the universe.
A scientist whose passion for cold runs red hot, Streever is a wondrous guide: he conjures woolly mammoth carcasses and the ice-age Clovis tribe from melting glaciers, and he evokes blizzards so wild readers may freeze--limb by vicarious limb.
Stephen Simpson and David Raubenheimer provide a comprehensive theoretical approach to the analysis of nutrition--the Geometric Framework. They show how it can help us to understand the links between nutrition and the biology of individual animals, including the physiological mechanisms that determine the nutritional interactions of the animal with its environment, and the consequences of these interactions in terms of health, immune responses, and lifespan. Simpson and Raubenheimer explain how these effects translate into the collective behavior of groups and societies, and in turn influence food webs and the structure of ecosystems. Then they demonstrate how the Geometric Framework can be used to tackle issues in applied nutrition, such as the problem of optimizing diets for livestock and endangered species, and how it can also help to address the epidemic of human obesity and metabolic disease.
Drawing on a wealth of examples from slime molds to humans, The Nature of Nutrition has important applications in ecology, evolution, and physiology, and offers promising solutions for human health, conservation, and agriculture.
Communicating the passion of the scientists who have driven the discipline, John Byers draws together evolutionary theory, ecology, population biology, genetics, physiology, and anatomy to demonstrate the diversity involved when studying animals. By explaining the mechanisms and motivations behind a range of animal movements he illuminates key issues about our own behavior while equipping readers with the core knowledge and skills to further their own studies.

Jonathan Balcombe, animal behaviorist and author of the critically acclaimed Pleasurable Kingdom, draws on the latest research, observational studies and personal anecdotes to reveal the full gamut of animal experience—from emotions, to problem solving, to moral judgment. Balcombe challenges the widely held idea that nature is red in tooth and claw, highlighting animal traits we have disregarded until now: their nuanced understanding of social dynamics, their consideration for others, and their strong tendency to avoid violent conflict. Did you know that dogs recognize unfairness and that rats practice random acts of kindness? Did you know that chimpanzees can trounce humans in short-term memory games? Or that fishes distinguish good guys from cheaters, and that birds are susceptible to mood swings such as depression and optimism?
With vivid stories and entertaining anecdotes, Balcombe gives the human pedestal a strong shake while opening the door into the inner lives of the animals themselves.
· Number of species included is increased from 6300 to over 8700, about 85% of the world’s birds
· Better data for many of the species included in the first edition — an exhaustive compilation of new data published from 1992 through 2007
· More comprehensive coverage of Latin America, Japan, Taiwan, Southeast Asia, and more coverage of research published in non-English language journals
In 1992 the CRC Handbook of Avian Body Masses broke new ground by providing a compilation of body masses for 6300 species, about two-thirds of the world’s species. The handbook instantly became the gold standard, cited in hundreds of scientific studies and a prominent fixture on the shelves of many ornithologists. Keeping the format that made the first edition so popular, the second edition features dramatic changes both in species coverage and the data quality.
The new edition compiles the results of new samples that have been published for many of the birds included in the first edition, and data found for about 2400 new species, increasing the coverage to over 8700 species, about 85% of the world’s birds. The order of species and families has been revised in the text to fit with the latest publications in avian taxonomy and systematics. The second edition includes an accompanying CD-ROM with a searchable electronic database.
A sighting in the field is just one way birders can identify bird species. Observant nature-lovers can discover what birds are where by examining tracks, trails, and a variety of bird sign: discarded feathers, feeding leftovers and caches, pellets, nests, droppings, and skulls and bones. This fully illustrated guide--the first of its kind for North American birds--presents thorough and straightforward instruction for identifying bird families or individual species by careful examination of the unique sign they leave behind. It also offers keys to the birds' behavior in the wild.
