    The largest of them, the Siberian tiger, is today almost entirely confined to the little-populated Russian Far East, a region that may offer the species' best hope for survival. But the implosion of the Soviet Union intensified poaching and habitat depredation, prompting a group of Russian researchers and U.S. wildlife biologists led by Maurice Hornocker to join forces to stave off extinction.Peter Matthiessen brings to the Siberian tiger the deep knowledge of and feeling for the natural world that have made classics of his previous books. Accompanying researchers into the field, he allows the reader to participate vicariously in the battle for the tiger's future. Along the way, he tells how the species evolved and evokes its crucial, often totemic role in human cultures and mythologies. He has made of the tiger's dilemma a drama-underscored by Hornocker's one-of-a-kind photographs-that conveys powerfully what a loss to our collective imagination the disappearance of these great cats would be.

    Scientists have discovered that the way cats and dogs lap up liquids can be explained by the laws of surface tension, how ants navigate is due to polarized light, and why pistol shrimps can generate enough force to destroy aquarium glass using their ”elbows”!Each of FURRY LOGIC's six chapters tackles a separate branch of physics and, through more than 30 animal case studies, examines each creature's key features before describing the ways physics is at play in its life, how the connection between physics and animal behavior was discovered, and what remains to be found out. Science journalists Matin Durrani and Liz Kalaugher make the incredible interdisciplinary world of animals accessible to all, in an enthralling and entertaining read.

    Lying in the eastern Pacific Ocean, straddling the equator off the west coast of South America, the Galágos is the most pristine archipelago to be found anywhere in the tropics. It is so remote, so untouched, that the act of wading ashore can make you feel like you are the first to do so. Yet the Galágos is far more than a wild paradise on earth-it is one of the most important sites in the history of science. Home to over 4,000 species native to its shores, around 40 percent of them endemic, the islands have often been called a "laboratory of evolution." The finches collected on the Galágos inspired Darwin's revolutionary theory of natural selection. In The Galágos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its course from deserted wilderness to biological testing ground and global ecotourism hot spot. Describing the island chain's fiery geological origins as well as our species' long history of interaction with the islands, he draws vivid portraits of the life forms found in the Galágos, capturing its awe-inspiring landscapes, understated flora, and stunning wildlife. Nicholls also reveals the immense challenges facing the islands, which must continually balance conservation and ever encroaching development. Beautifully weaving together natural history, evolutionary theory, and his own experience on the islands, Nicholls shows that the story of the Galágos is not merely an isolated concern, but reflects the future of our species' relationship with nature-and the fate of our planet.

    Enter a beehive--one part nursery, one part honey factory, one part queen bee sanctum--then fly through backyard gardens, open fields, and deserts where wildflowers bloom. It's fascinating--and delicious!Hailed for their hard work and harmonious society, bees make possible life on earth as we know it. This fundamental link between bees and humans reaches beyond biology to our environment and our culture: bees have long played important roles in art, religion, literature, and medicine--and, of course, in the kitchen.For honey fanatics and all who have a sweet tooth, this book not only entertains and enlightens but also reminds us of the fragility of humanity's relationship with nature. Includes illustrations and photographs throughout.

    Though the process obeyed all the rules of chemistry and physics, the details of that original event pose as deep a mystery as any facing science. How did non-living chemicals become alive? While the question is (deceivingly) simple, the answers are unquestionably complex. Science inevitably plays a key role in any discussion of life's origins, dealing less with the question of why life appeared on Earth than with where, when, and how it emerged on the blasted, barren face of our primitive planet. Astrobiologist Robert Hazen has spent many years dealing with the fundamental questions of life's genesis. As an active research scientist, he is down deep in all the messy details that science has to offer on the subject, tracing the inexorable sequence of events that led to the complicated interactions of carbonbased molecules. As he takes us through the astounding process of emergence, we are witness to the first tentative steps toward life?from the unfathomable abundance of carbon biomolecules synthesized in the black vacuum of space to the surface of the Earth to deep within our planet's restless crust. We are privy to the breathtaking drama that rapidly unfolds as life prevails. The theory of emergence is poised to answer a multitude of questions?even as it raises the possibility that natural processes exist beyond what we now know, perhaps beyond what we even comprehend. Genesis tells the tale of transforming scientific advances in our quest for life's origins. Written with grace, beauty, and authority, it goes directly to the heart of who we are and why we are here.

    Cavalli-Sforza and others have answered this question—anticipated by Darwin—with a decisive yes. Genes, Peoples, and Languages comprises five lectures that serve as a summation of the author's work over several decades, the goal of which has been nothing less than tracking the past hundred thousand years of human evolution.Cavalli-Sforza raises questions that have serious political, social, and scientific import: When and where did we evolve? How have human societies spread across the continents? How have cultural innovations affected the growth and spread of populations? What is the connection between genes and languages? Always provocative and often astonishing, Cavalli-Sforza explains why there is no genetic basis for racial classification.

    The award-winning zoologists and pioneering conservationists describe their work in the remote and ruggedly beautiful Luangwa Valley, in northeastern Zambia. There they studied the mysteries of the elephant population’s recovery after poaching, discovering remarkable similarities between humans and elephants. A young elephant named Gift provided the clue to help them crack the animals’ secret of survival. A stirring portrait of life in Africa, Secrets of the Savanna is a remarkable record of the Owenses' unique passions.

    Of a Feather traces the colorful origins of American birding: the frontier ornithologists who collected eggs between border skirmishes; the society matrons who organized the first effective conservation movement; and the luminaries with checkered pasts, such as Alexander Wilson (a convicted blackmailer) and the endlessly self-mythologizing John James Audubon. Scott Weidensaul also recounts the explosive growth of modern birding that began when an awkward schoolteacher named Roger Tory Peterson published A Field Guide to the Birds in 1934. Today birding counts iPod-wearing teens and obsessive "listers" among its tens of millions of participants, making what was once an eccentric hobby into something so completely mainstream it's now (almost) cool. This compulsively readable popular history will surely find a roost on every birder's shelf.

    alone, their numbers surpassed only by dogs and cats, yet these complex creatures are not your typical domesticated animal, and they remain a mystery to many. Most people don’t know that parrots score at the level of 3-to-5 year olds on human intelligence tests. Nor that they can live to 100 years or more. Nor that pound for pound parrots are worth more on the black market than cocaine. Their startling beauty, social sophistication, and uncanny ability to bond with humans have made parrots sought-after pets, but few people realize how fragile and endangered many parrot species have become. In Of Parrots and People, award-winning journalist and parrot expert, Mira Tweti, reveals the world of a family of birds that is far more complex and advanced than we’ve acknowledged. Tweti relates stunning scientific findings on the intelligence, personality, and rich lives of parrots that challenge our most widespread and flawed assumptions about non-primates. And she explores the intense and often humorous emotional connections these birds form not just with their flockmates, but with the “parronts” (as some “parrot parents” call themselves) who keep them as pets, often pampering them as they do children. Of Parrots and People also takes on the much larger, serious issues of animal welfare that are the unfortunate consequences of the “bird boom” of the last few decades. Despite the high demand for them, many parrot species are endangered in the wild from rampant trapping and habitat destruction, while those in captivity are quickly becoming the fastest growing category of unwanted pets, living lives of neglect or abuse. Avian rescuers can’t handle the number of birds that need help, and the Humane Society of the U.S. is advocating euthanasia rather than warehousing birds that will outlive their caretakers. Yet unregulated bird breeders continue to put over a million young birds on the market each year from parrot mills across the country. It’s an untenable situation of cruelty, especially for such an evolved and intelligent species, and it’s just one of the many newsworthy topics that make Of Parrots and People just as hard-hitting as it is soft-hearted. Tweti tirelessly follows the parrot trail around the globe, from the living rooms and pet stores of America, to hotbeds of illegal trade in Mexico. She examines threats of avian flu, and takes a first hand look at encouraging progress in eco-tourism that may be our only way to protect these stunning species from being hunted to extinction. Comprehensive in scope and passionately written, Of Parrots and People is a unique and vivid addition to popular works on animals and their behavior, and an important new voice in the burgeoning environmental and conservation movement.

    Chief among these naysayers was the French Count and world-renowned naturalist Georges-Louis Leclerc de Buffon, who wrote that the flora and fauna of America (humans included) were inferior to European specimens. Thomas Jefferson—author of the Declaration of Independence, U.S. president, and ardent naturalist—spent years countering the French conception of American degeneracy. His Notes on Virginia systematically and scientifically dismantled Buffon’s case through a series of tables and equally compelling writing on the nature of his home state. But the book did little to counter the arrogance of the French and hardly satisfied Jefferson’s quest to demonstrate that his young nation was every bit the equal of a well-established Europe. Enter the giant moose. The American moose, which Jefferson claimed was so enormous a European reindeer could walk under it, became the cornerstone of his defense. Convinced that the sight of such a magnificent beast would cause Buffon to revise his claims, Jefferson had the remains of a seven-foot ungulate shipped first class from New Hampshire to Paris. Unfortunately, Buffon died before he could make any revisions to his Histoire Naturelle, but the legend of the moose makes for a fascinating tale about Jefferson’s passion to prove that American nature deserved prestige. In Mr. Jefferson and the Giant Moose, Lee Alan Dugatkin vividly recreates the origin and evolution of the debates about natural history in America and, in so doing, returns the prize moose to its rightful place in American history.

    Its clear, user-friendly descriptions of the genetics and neuroscience behind the disorder is paired with first person descriptions and personal narratives of what biological differences mean to sufferers. Author Carrie Arnold, a trained scientist, science writer, and past sufferer of anorexia, speaks with clinicians, researchers, parents, other family members, and sufferers about the factors that make one vulnerable to anorexia, the neurochemistry behind the call of starvation, and why it's so hard to leave anorexia behind. She also addresses: - How environment is still important and influences behaviors- The characteristics of people at high risk for developing anorexia nervosa- Why anorexics find starvation "rewarding"- Why denial is such a salient feature, and how sufferers can overcome itCarrie also includes interviews with key figures in the field who explain their work and how it contributes to our understanding of anorexia. Long thought to be a psychosocial disease of fickle teens, this book alters the way anorexia is understood and treated and gives patients, their doctors, and their family members hope.
