It has an ecological approach that explains the fundamentals of soil science effectively. Chapter topics include Soil Erosion and Its Control, Soil Acidity, Soils and Chemical Pollution, and Organisms and the Ecology of the Soil. For individuals interested in soil and the environment."

    It traces the origins of the concept, discusses the thinkers who have shaped it, and shows how it in turn has shaped the modern perception of our place in nature. The book includes portraits of Linnaeus, Gilbert White, Darwin, Thoreau, and such key twentieth-century ecologists as Rachel Carson, Frederic Clements, Aldo Leopold, James Lovelock, and Eugene Odum. It concludes with a new Part VI, which looks at the directions ecology has taken most recently.

    The complexity of nature's shapes differs in kind, not merely degree, from that of the shapes of ordinary geometry, the geometry of fractal shapes.Now that the field has expanded greatly with many active researchers, Mandelbrot presents the definitive overview of the origins of his ideas and their new applications. The Fractal Geometry of Nature is based on his highly acclaimed earlier work, but has much broader and deeper coverage and more extensive illustrations.

    Once-lush grasslands, the source of precious food and water, are growing dry and bare. Rivers that used to flow year-round now run dry after the rains. Grazing animals want for food. What is causing this “desertification” of the earth, and how can we stop it? In The Grazing Revolution, biologist Allan Savory presents a solution that’s as radical as it is simple: huge herds of livestock, managed to mimic the behavior of the natural herds that once roamed grasslands centuries ago. Tracing his own story of discovery, Savory debunks common misconceptions and provides a vivid chronicle of the process by which he has seen scrubby wasteland revert to robust ecosystems. Our age-old agricultural practices are contributing greatly to the global climate change underway; Savory argues that by re-imagining these practices, we can reverse desertification and save the planet.

    In case study format, this informative reference answers questions surrounding nuclear energy, the potential of sustainable fossil fuels, and the possibilities of sharing renewable power with foreign countries. While underlining the difficulty of minimizing consumption, the tone remains positive as it debunks misinformation and clearly explains the calculations of expenditure per person to encourage people to make individual changes that will benefit the world at large.

    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.

    Whether William Bryant Logan is traversing the far reaches of the cosmos or plowing through our planet’s crust, his delightful, elegant, and surprisingly soulful meditations greatly enrich our concept of "dirt," that substance from which we all arise and to which we all must return.

    Also known as the Yellowstone Earthquake, the disaster caused massive flooding and the worst landslide in the history of the Northwestern United States. In The Night the Mountain Fell author Edmund Christopherson gives us a page-turning, journalistic-style account of how the deadliest earthquake in Montana's history ultimately claimed the lives of twenty-eight people.

    In 1992, in a remote mountain range, a team of scientists discovered the remains of an unusual animal with exquisite long horns. It turned out to be a living species new to Western science -- a saola, the first large land mammal discovered in fifty years. Rare then and rarer now, a live saola had never been glimpsed by a Westerner in the wild when Pulitzer Prize finalist and nature writer William deBuys and conservation biologist William Robichaud set off to search for it in central Laos. Their team endured a punishing trek up and down white-water rivers and through mountainous terrain ribboned with the snare lines of armed poachers who roamed the forest, stripping it of wildlife. In the tradition of Bruce Chatwin, Colin Thubron, and Peter Matthiessen, The Last Unicorn chronicles deBuys's journey deep into one of the world's most remote places. It's a story rich with the joys and sorrows of an expedition into undiscovered country, pursuing a species as rare and elusive as the fabled unicorn. As is true with the quest for the unicorn, in the end the expedition becomes a search for something more: the essence of wildness in nature, evidence that the soul of a place can endure, and the transformative power of natural beauty.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    David Owen traces all that water from the Colorado's headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.–Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on.The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert, and the disastrous consequences we face when any part of this tenuous system fails.

    Over the past decade, the world has seen the most powerful El Ni�o ever recorded, the most devastating hurricane in two hundred years, the hottest European summer on record, and one of the worst storm seasons ever experienced in Florida. With one out of every five living things on this planet committed to extinction by the levels of greenhouse gases that will accumulate in the next few decades, we are reaching a global climatic tipping point. The Weather Makers is both an urgent warning and a call to arms, outlining the history of climate change, how it will unfold over the next century, and what we can do to prevent a cataclysmic future. Along with a riveting history of climate change, Tim Flannery offers specific suggestions for action for both lawmakers and individuals, from investing in renewable power sources like wind, solar, and geothermal energy, to offering an action plan with steps each and every one of us can take right now to reduce deadly CO2 emissions by as much as 70 percent.

    An evolutionary perspective forms the foundation of the entire discussion. The book begins with the natural history of the planet, considers portions of the whole in the middle chapters, and ends with another perspective of the entire planet in the concluding chapter. Its unique organization of focusing only on several key concepts in each chapter sets it apart from the competition. .
