Considered by many to be his greatest book, it is as relevant today as when it was first published.

    Yet this enigmatic animal is more complex than the legends that surround it. With a shrinking wilderness and global warming, the future of the wolverine is uncertain. The Wolverine Way reveals the natural history of this species and the forces that threaten its future, engagingly told by Douglas Chadwick, who volunteered with the Glacier Wolverine Project. This five-year study in Glacier National Park – which involved dealing with blizzards, grizzlies, sheer mountain walls, and other daily challenges to survival – uncovered key missing information about the wolverine’s habitat, social structure and reproduction habits. Wolverines, according to Chadwick, are the land equivalent of polar bears in regard to the impacts of global warming. The plight of wolverines adds to the call for wildlife corridors that connect existing habitat that is proposed by the Freedom to Roam coalition.

    An Introduction to Meteorology (13th Edition)

    It is intended to demystify ecological models and the mathematics behind them by deriving the models from first principles. The Primer explains in detail basic concepts of exponential and logistic population growth, age-structured demography, metapopulation dynamics, competition, predation, island biogeography, and, in a chapter new to this edition, succession. The book may be used as a self-teaching tutorial by students, as a primary textbook, or as a supplemental text to a general ecology textbook.

    In their place evolved an enormous variety of land creatures, especially the mammals, which in their way were every bit as remarkable as their Mesozoic cousins.The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth gigantic hornless rhinos, sabertooth cats, mastodonts and mammoths, and many other creatures--including our own ancestors.Their story is part of a larger story of a world emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth's vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles, to grasslands and savannas across the entire world. Life in the sea also underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales.After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.

    This man was a freediver, and his amphibious abilities inspired Nestor to seek out the secrets of this little-known discipline. In Deep, Nestor embeds with a gang of extreme athletes and renegade researchers who are transforming not only our knowledge of the planet and its creatures, but also our understanding of the human body and mind. Along the way, he takes us from the surface to the Atlantic’s greatest depths, some 28,000 feet below sea level. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and seals who dive to depths below 2,400 feet for up to eighty minutes—deeper and longer than scientists ever thought possible. As strange as these phenomena are, they are reflections of our own species’ remarkable, and often hidden, potential—including echolocation, directional sense, and the profound physiological changes we undergo when underwater. Most illuminating of all, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.

    In How Plants Work, horticulture expert Linda Chalker-Scott brings the stranger-than-fiction science of the plant world to vivid life. She uncovers the mysteries of how and why plants do the things they do, and arms you with fascinating knowledge that will change the way you garden.

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realize that 1 per cent of the static on a TV tuned between stations is the relic of the Big Bang? These and many other remarkable facts about the world are direct consequences of quantum physics and relativity. Quantum theory has literally made the modern world possible. Not only has it given us lasers, computers, and nuclear reactors, but it has provided an explanation of why the sun shines and why the ground beneath our feet is solid. Despite this, however, quantum theory and relativity remain a patchwork of fragmented ideas, vaguely understood at best and often utterly mysterious. average person. Author Marcus Chown emphatically disagrees. As Einstein himself said, Most of the fundamental ideas of science are essentially simple and may, as a rule, be expressed in a language comprehensible to everyone. If you think that the marvels of modern physics have passed you by, it is not too late. In Chown's capable hands, quantum physics and relativity are not only painless but downright fun. So sit back, relax, and get comfortable as an adept and experienced science communicator brings you quickly up to speed on some of the greatest ideas in the history of human thought.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.

    Through Maloof’s engaging, conversational style, each essay offers a lesson in stewardship as it explores the interwoven connections between a tree species and the animals and insects whose lives depend on it--and who, in turn, work to ensure the tree’s survival.Never really at home in a laboratory, Maloof took to the woods early in her career. Her enthusiasm for firsthand observation in the wild spills over into her writing, whether the subject is the composition of forest air, the eagle’s preference for nesting in loblolly pines, the growth rings of the bald cypress, or the gray squirrel’s fondness for weevil-infested acorns. With a storyteller’s instinct for intriguing particulars, Maloof expands our notions about what a tree “is” through her many asides--about the six species of leafhoppers who eat only sycamore leaves or the midges who live inside holly berries and somehow prevent them from turning red.As a scientist, Maloof accepts that trees have a spiritual dimension that cannot be quantified. As an unrepentant tree hugger, she finds support in the scientific case for biodiversity. As an activist, she can’t help but wonder how much time is left for our forests.

    In April 2003, wildlife biologist Karsten Heuer and filmmaker Leanne Allison embarked on a five-month research journey to follow the 2,000-mile migration of a herd of 120,000 Porcupine Caribou, from their winter range to their calving grounds in Alaska, and back again. From Old Crow, Yukon, the Heuers followed ancient paths and the primordial rhythms of the herd through Canada and over the border to the Arctic National Wildlife Refuge in the United States. The couple travelled on foot and by ski through unforgiving landscapes; fording swift, deadly cold rivers, as well as encountering ravenous grizzlies who tracked them as prey. Having began the expedition as seasoned outdoor adventurers, Karsten and Leanne soon learned they would only be able to find and discern the intent of the herd by adopting the ancient ways of the area's indigenous people. Advised by a Gwich'in native in Old Crow at the start of their trip to "listen to dreams", Karsten and Leanne find they must shed the many insulating layers of pragmatism that distance them from the natural world. They discover a transformational truth in listening to the music of the earth, paying attention to the urgings within dreams, and in truly, beyond their expectations, being caribou.

    In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere.Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda Mapes takes us through a year with the tree in the Harvard Forest. We learn about carbon cycles and leaf physiology, but we also experience seasons of change as people have for centuries, watching for each new bud, and listening for each new bird and frog call. Lynda takes us high into the oak's swaying boughs, cores deep into its heartwood, and digs into its roots and teeming soil. She brings us eye level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns.Though stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It's an inescapable document of climate change, but also an environmental story rooted in hope, beauty, wonder, and the possibility of renewal in people and the world around us.
