    In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life.We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

    In it she tells the story of a miraculous ocean encounter that happened to her when she was seventeen and in training for a big swim (she had already swum the English Channel, twice, and the Catalina Channel).It was the dark of early morning; Lynne was in 55-degree water as smooth as black ice, two hundred yards offshore, outside the wave break. She was swimming her last half-mile back to the pier before heading home for breakfast when she became aware that something was swimming with her. The ocean was charged with energy as if a squall was moving in; thousands of baby anchovy darted through the water like lit sparklers, trying to evade something larger. Whatever it was, it felt large enough to be a white shark coursing beneath her body.It wasn't a shark. It became clear that it was a baby gray whale—following alongside Lynne for a mile or so. Lynne had been swimming for more than an hour; she needed to get out of the water to rest, but she realized that if she did, the young calf would follow her onto shore and die from collapsed lungs.The baby whale—eighteen feet long!—was migrating on a three-month trek to its feeding grounds in the Bering Sea, an eight-thousand-mile journey. It would have to be carried on its mother's back for much of that distance, and was dependent on its mother's milk for food—baby whales drink up to fifty gallons of milk a day. If Lynne didn't find the mother whale, the baby would suffer from dehydration and starve to death.Something so enormous—the mother whale was fifty feet long—suddenly seemed very small in the vast Pacific Ocean. How could Lynne possibly find her?This is the story—part mystery, part magical tale—of what happened . . .

    . .· The almost inconceivable number of creatures in the marine world. From the bounty of microbes in one drop of seawater, we can calculate that there are more individuals in the oceans than stars in the universe.· The sophisticated sensory abilities that help these animals survive. For many, the standard five senses are just not enough.· The incredible distances that seabirds and other species cover. Some will feed in both Arctic and Antarctic waters within a single year.· The odd relationships common in the marine world. From a dental hygienist for fish to a walrus's one-night stand, you'll find beauty, practicality, and plenty of eccentricity in sea-life socialization.Brilliantly photographed and written in an easygoing style, Citizens of the Sea will inform and enchant you with close-up documentation of the fascinating facts of life in the ocean realm.

    It's a watery force connected to the earth, climate control and so to the eventual fate of the human race.Whitty's thirty-year career as a documentary filmmaker and diver has given her sustained access to the scientists dedicated to the study of an astonishing range of ocean life, from the physiology of extremophile life forms to the strategies of nesting seabirds to the ecology of whale falls (what happens upon the death of a behemoth).No stranger to extreme adventure, Whitty travels the oceanside and underwater world from the Sea of Cortez to Newfoundland to Antarctica. In the Galapagos, in one of the book's most haunting encounters, she realizes: "I am about to learn the answer to my long-standing question about what would happen to a person in the water if a whale sounded directly alongside: would she, like a person afloat beside a sinking ship, be dragged under too?" This book provides extraordinary armchair entree to gripping adventure, cutting-edge science, and an intimate understanding of our deep blue home.

    At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water—but there is no surplus: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still. Dead Pool, featuring rarely seen historical photographs, explains why America built the dam that made Lake Powell and others like it and then allowed its citizens to become dependent on their benefits, which were always temporary. Writing for a wide audience, Powell shows us exactly why an urgent threat during the first half of the twenty-first century will come not from the rising of the seas but from the falling of the reservoirs.

    This book traces the course of the river through four centuries, recounting the stories of explorers and traders, artists and writers, entrepreneurs and industrialists, ecologists and preservationists—those who have been shaped by the river as well as those who have helped shape it. Their compelling narratives attest to the Hudson River’s distinctive place in American history and the American imagination. Among those who have figured in the history of the Hudson are Benedict Arnold, Alexander Hamilton, Franklin and Eleanor Roosevelt, the Astors and the Vanderbilts, and Thomas Cole of the Hudson River school. Their stories appear here, alongside those of such less famous individuals as the surveyor who found the source of the Hudson and the engineer who tried to build a hydroelectric plant at Storm King Mountain. Inviting us to view the river from a wider perspective than ever before, this entertaining and enlightening book is worthy of its grand subject.

    But now, suddenly, the turtles are dying, ravaged by a mysterious plague that some biologists consider the most serious epidemic now raging in the natural world. Perhaps most important, sea turtles aren't the only marine creatures falling prey to deadly epidemics. Over the last few decades diseases have been burning through nearshore waters around the world with unprecedented lethality. What is happening to the sea turtle, and how can it be stopped? In this fascinating scientific detective story, Osha Gray Davidson tracks the fervent efforts of the extraordinary and often quirky scientists, marine biologists, veterinarians, and others racing against the clock to unravel a complicated biological and environmental puzzle and keep the turtles from extinction. He follows the fates of particular turtles, revealing their surprisingly distinct personalities and why they inspire an almost spiritual devotion in the humans who come to know them. He also explores through vivid historical anecdotes and examples the history of man's relationship to the sea, opening a window onto the role played by humans in the increasing number of marine die-offs and extinctions. Beautifully written, intellectually provocative, Fire in the Turtle House reveals how emerging diseases wreaking havoc in the global ocean pose an enormous, direct threat to humanity. This is science journalism at its best.

    Gillet, at the age of 36 an accomplished sailor and paddler, navigated by sextant and always knew his position within a few miles. Still, Gillet underestimated the abuse his body would take from the relentless, pounding, swells of the Pacific, and early into his voyage he was covered with salt water sores and found that he could find no comfortable position for sitting or sleeping. Along the way he endured a broken rudder, among other calamities, but at last reached Maui on his 63rd day at sea, four days after his food had run out. Dave Shively brings Gillet's remarkable story to life in this gripping narrative, based on exclusive access to Gillet's logs as well as interviews with the legendary paddler himself.

    Harlen Bretz walked the dry scabland channels of eastern Washington in the 1920s, it dawned on him that he was viewing a landscape sculpted by water. Lots of water. A flood of catastrophic proportions. Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean. This is also the story of geologists grappling with scientific controversy--"of how personalities, pride, and prejudice sometimes superseded scientific evidence."
