Nature's Calendar: A Year in the Life of a Wildlife Sanctuary

by Colin Rees

Take an enchanting journey through the shifting seasons in a wildlife sanctuary home to wetland, forest, and grassland and supporting an incredible diversity of plants and animals.Flocks of waterfowl exploding into steely skies above frozen marshland, salamanders creeping across the forest floor to vernal pools, chorusing frogs peeping their ecstasy while warblers crowd budding trees, turtles sunning on floating logs, the ecological engineering of beavers—these are but a few of the sights and sounds marking a year at Jug Bay Wetlands Sanctuary and its neighboring landscapes in Southern Maryland. In an absorbing account of a year in the life of this sanctuary, naturalist Colin Rees invites us to join him as he explores the secrets and wonders of the changing natural world. Alongside the author, we witness spring's avian migrations, quickening of aquatic vegetation, burgeoning of myriad invertebrates, and the assaults of extreme weather conditions. We revel in summertime's proliferation of fish, fowl, and mammals. We become attuned to the shifting climate's impacts on autumnal transitions, and we marvel at amazing feats of biological inventiveness in preparation for winter conditions. Through these visions of the fleeting—and yet enduring—cycles of nature, Rees shares deep insights into the ecological and behavioral dynamics of the natural environment. Enhanced by more than two dozen color plates, the book touches on a wide range of issues, from microbial diversity, bird banding, and butterfly phenology to genetic diversity and habitat fragmentation. It also examines the challenges of conserving these and other natural features in the face of climate change and development pressures. Thoughtful and lyrical, Nature's Calendar speaks to all readers, scientific and lay alike. Fascinating profiles of flora and fauna celebrate the richness and complexity of a unique ecosystem, exploring the entire ecology of this dynamic and delicate area.

Nature's Champion

by James R. Troyer

Through the pioneering efforts of ecologist B. W. Wells (1884-1978), thousands of North Carolinians learned to appreciate and protect the state's diverse plant life long before ecology and conservation became popular causes. A keen observer of the natural landscape, Wells provided the first scientific descriptions in modern terms of the forces that shaped coastal communities, bogs and savannahs, the Carolina bays, pine forests, old fields, and mountain grassy balds. But the broader impact of his life lay in his championship and popularization of nature. Outside academic circles, he shared his knowledge through public lectures, articles, and lobbying efforts, and by teaching anyone who would listen. In 1932 he produced for his Tar Heel audience a revolutionary work on the plant ecology of the state, The Natural Gardens of North Carolina. Organized by habitat, this volume is still entertaining and instructive. Wells received his Ph.D. in botany from the University of Chicago in 1917 and served as chair of the North Carolina State College botany department for thirty years. He was a memorable teacher and a significant force in the development of his academic institution.

Nature’s Clocks: How Scientists Measure the Age of Almost Everything

by Doug Macdougall

"Radioactivity is like a clock that never needs adjusting," writes Doug Macdougall. "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating--the best known of these methods--and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves--James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson--Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

Nature's Compass: The Mystery of Animal Navigation (Science Essentials #16)

by James L. Gould Carol Grant Gould

The mysterious and remarkable ways that animals navigateWe know that animals cross miles of water, land, and sky with pinpoint precision on a daily basis. But it is only in recent years that scientists have learned how these astounding feats of navigation are actually accomplished. With colorful and thorough detail, Nature's Compass explores the remarkable methods by which animals find their way both near home and around the globe. Noted biologist James Gould and popular science writer Carol Gould delve into the elegant strategies and fail-safe backup systems, the invisible sensitivities and mysterious forces, and incredible mental abilities used by familiar and rare species, as they investigate a multitude of navigation strategies, from the simple to the astonishing.The Goulds discuss how animals navigate, without instruments and training, at a level far beyond human talents. They explain how animals measure time and show how the fragile monarch butterfly employs an internal clock, calendar, compass, and map to commence and measure the two-thousand-mile annual journey to Mexico—all with a brain that weighs only a few thousandths of an ounce. They look at honey bees and how they rely on the sun and mental maps to locate landmarks such as nests and flowers. And they examine whether long-distance migrants, such as the homing pigeon, depend on a global positioning system to let them know where they are. Ultimately, the authors ask if the disruption of migratory paths through habitat destruction and global warming is affecting and endangering animal species.Providing a comprehensive picture of animal navigation and migration, Nature's Compass decodes the mysteries of this extraordinary aspect of natural behavior.

Nature's Economy

by Donald Worster

Nature's Economy is a wide-ranging investigation of ecology's past, first published in 1994. 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. Our view of the living world is a product of culture, and the development of ecology since the eighteenth century has closely reflected society's changing concerns. Donald Worster focuses on these dramatic shifts in outlook and on the individuals whose work has expressed and influenced society's point of view. 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.

Nature's Fabric: Leaves in Science and Culture

by David Lee

Leaves are all around us—in backyards, cascading from window boxes, even emerging from small cracks in city sidewalks given the slightest glint of sunlight. Perhaps because they are everywhere, it’s easy to overlook the humble leaf, but a close look at them provides one of the most enjoyable ways to connect with the natural world. A lush, incredibly informative tribute to the leaf, Nature’s Fabric offers an introduction to the science of leaves, weaving biology and chemistry with the history of the deep connection we feel with all things growing and green. Leaves come in a staggering variety of textures and shapes: they can be smooth or rough, their edges smooth, lobed, or with tiny teeth. They have adapted to their environments in remarkable, often stunningly beautiful ways—from the leaves of carnivorous plants, which have tiny “trigger hairs” that signal the trap to close, to the impressive defense strategies some leaves have evolved to reduce their consumption. (Recent studies suggest, for example, that some plants can detect chewing vibrations and mobilize potent chemical defenses.) In many cases, we’ve learned from the extraordinary adaptations of leaves, such as the invention of new self-cleaning surfaces inspired by the slippery coating found on leaves. But we owe much more to leaves, and Lee also calls our attention back to the fact that that our very lives—and the lives of all on the planet—depend on them. Not only is foliage is the ultimate source of food for every living thing on land, its capacity to cycle carbon dioxide and oxygen can be considered among evolution’s most important achievements—and one that is critical in mitigating global climate change. Taking readers through major topics like these while not losing sight of the small wonders of nature we see every day—if you’d like to identify a favorite leaf, Lee’s glossary of leaf characteristics means you won’t be left out on a limb—Nature’s Fabric is eminently readable and full of intriguing research, sure to enhance your appreciation for these extraordinary green machines.

Nature's Frontiers: Achieving Sustainability, Efficiency, and Prosperity with Natural Capital (Environment and Sustainable Development)

by Richard Damania Stephen Polasky Mary Ruckelshaus Russ Rebecca Chaplin-Kramer James Gerber Peter Hawthorne Martin Philipp Heger Saleh Mamun Giovanni Ruta Rafael Schmitt Jeffrey Smith Adrian Vogl Fabian Wagner

The great expansion of economic activity since the end of World War II has caused an unprecedented rise in living standards, but it has also caused rapid changes in earth systems. Nearly all types of natural capital—the world’s stock of resources and services provided by nature—are in decline. Clean air, abundant and clean water, fertile soils, productive fisheries, dense forests, and healthy oceans are critical for healthy lives and healthy economies. Mounting pressures, however, suggest that the trend of declining natural capital may cast a long shadow into the future. Nature’s Frontiers: Achieving Sustainability, Efficiency, and Prosperity with Natural Capital presents a novel approach to address these foundational challenges of sustainability. A methodology combining innovative science, new data sources, and cutting-edge biophysical and economic models builds sustainable resource efficiency frontiers to assess how countries can sustainably use their natural capital more efficiently. The analysis provides recommendations on how countries can better use their natural capital to achieve their economic and environ mental goals. The report indicates that significant efficiency gaps exist in nearly every country. Closing these gaps can address many of the world’s pressing economic and environmental problems—economic productivity, health, food and water security, and climate change. Although the approach outlined in this report will entail demanding policy reforms, the costs of inaction will be far higher.

Nature's Ghosts: Confronting Extinction from the Age of Jefferson to the Age of Ecology

by Mark V. Barrow Jr.

A historical narrative of endangered animals and the dedicated individuals who have studied and struggled to protect them, offering an unprecedented view of what we've lost and a stark reminder of the hard work of preservation still ahead.

Nature's Ghosts: Confronting Extinction from the Age of Jefferson to the Age of Ecology

by Mark V. Barrow Jr.

The rapid growth of the American environmental movement in recent decades obscures the fact that long before the first Earth Day and the passage of the Endangered Species Act, naturalists and concerned citizens recognized—and worried about—the problem of human-caused extinction.As Mark V. Barrow reveals in Nature’s Ghosts, the threat of species loss has haunted Americans since the early days of the republic. From Thomas Jefferson’s day—when the fossil remains of such fantastic lost animals as the mastodon and the woolly mammoth were first reconstructed—through the pioneering conservation efforts of early naturalists like John James Audubon and John Muir, Barrow shows how Americans came to understand that it was not only possible for entire species to die out, but that humans themselves could be responsible for their extinction. With the destruction of the passenger pigeon and the precipitous decline of the bison, professional scientists and wildlife enthusiasts alike began to understand that even very common species were not safe from the juggernaut of modern, industrial society. That realization spawned public education and legislative campaigns that laid the foundation for the modern environmental movement and the preservation of such iconic creatures as the bald eagle, the California condor, and the whooping crane.A sweeping, beautifully illustrated historical narrative that unites the fascinating stories of endangered animals and the dedicated individuals who have studied and struggled to protect them, Nature’s Ghosts offers an unprecedented view of what we’ve lost—and a stark reminder of the hard work of preservation still ahead.

Natures in Translation: Romanticism and Colonial Natural History

by Alan Bewell

Understanding the dynamics of British colonialism and the enormous ecological transformations that took place through the mobilization and globalized management of natures.For many critics, Romanticism is synonymous with nature writing, for representations of the natural world appear during this period with a freshness, concreteness, depth, and intensity that have rarely been equaled. Why did nature matter so much to writers of the late eighteenth and early nineteenth centuries? And how did it play such an important role in their understanding of themselves and the world?In Natures in Translation, Alan Bewell argues that there is no Nature in the singular, only natures that have undergone transformation through time and across space. He examines how writers—as disparate as Erasmus and Charles Darwin, Joseph Banks, Gilbert White, William Bartram, William Wordsworth, John Clare, and Mary Shelley—understood a world in which natures were traveling and resettling the globe like never before. Bewell presents British natural history as a translational activity aimed at globalizing local natures by making them mobile, exchangeable, comparable, and representable. Bewell explores how colonial writers, in the period leading up to the formulation of evolutionary theory, responded to a world in which new natures were coming into being while others disappeared. For some of these writers, colonial natural history held the promise of ushering in a "cosmopolitan" nature in which every species, through trade and exchange, might become a true "citizen of the world." Others struggled with the question of how to live after the natures they depended upon were gone. Ultimately, Natures in Translation demonstrates that—far from being separate from the dominant concerns of British imperial culture—nature was integrally bound up with the business of empire.

Nature's Matrix: Linking Agriculture, Conservation and Food Sovereignty

by Ivette Perfecto John Vandermeer Angus Wright

Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty. Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.

Nature's Matrix: Linking Agriculture, Biodiversity Conservation and Food Sovereignty

by Ivette Perfecto John Vandermeer Angus Wright

When first published in 2009, Nature’s Matrix set out a radical new approach to the conservation of biodiversity. This new edition pushes the frontier of the biodiversity/agriculture debate further, making an even stronger case for the need to transform agriculture and support small- and medium-scale agroecology and food sovereignty. In the first edition, the authors set out a radical new approach to the conservation of biodiversity. This is based on the concept of a landscape as a matrix of diverse, small-scale agricultural ecosystems, providing opportunities to enhance conservation under the stewardship of local farmers. This contrasts with the alternative view of industrial-scale farms and large protected areas which exclude local people. However, since then the debate around conservation and agriculture has developed significantly and this is reflected in this updated second edition. The text is thoroughly revised, including: a reorganization of chapters with new and timely topics introduced, updates to the discussion of agroecology and food sovereignty, bringing it in line with the current debates, greater coverage of the role of agroecology, in particular agroforestry, as an important component of climate change adaptation and mitigation, highlighting recent studies on the role of intensive agriculture in climate change and loss of biodiversity, and more attention given to the discussion of land sparing versus land sharing. By integrating the ecological aspects of agriculture and conservation biology, with a political and social analysis as well as historical perspective, the book continues to set a progressive agenda and appeals to a wide range of students and professionals.

Nature's Mirror: How Taxidermists Shaped America’s Natural History Museums and Saved Endangered Species

by Mary Anne Andrei

It may be surprising to us now, but the taxidermists who filled the museums, zoos, and aquaria of the twentieth century were also among the first to become aware of the devastating effects of careless human interaction with the natural world. <p><p> Witnessing firsthand the decimation caused by hide hunters, commercial feather collectors, whalers, big game hunters, and poachers, these museum taxidermists recognized the existential threat to critically endangered species and the urgent need to protect them. The compelling exhibits they created—as well as the scientific field work, popular writing, and lobbying they undertook—established a vital leadership role in the early conservation movement for American museums that persists to this day. <p><p> Through their individual research expeditions and collective efforts to arouse demand for environmental protections, this remarkable cohort—including William T. Hornaday, Carl E. Akeley, and several lesser-known colleagues—created our popular understanding of the animal world and its fragile habitats. For generations of museum visitors, they turned the glass of an exhibition case into a window on nature—and a mirror in which to reflect on our responsibility for its conservation.

Nature's Nether Regions

by Menno Schilthuizen

The story of evolution as you've never heard it before What's the easiest way to tell species apart? Check their genitals. Researching private parts was long considered taboo, but scientists are now beginning to understand that the wild diversity of sex organs across species can tell us a lot about evolution. Menno Schilthuizen invites readers to join him as he uncovers the ways the shapes and functions of genitalia have been molded by complex Darwinian struggles: penises that have lost their spines but evolved appendages to displace sperm; female orgasms that select or reject semen from males, in turn subtly modifying the females' genital shape. We learn why spiders masturbate into miniature webs, discover she dungflies that store sperm from attractive males in their bellies, and see how, when it comes to outlandish appendages and bizarre behaviors, humans are downright boring. Nature's Nether Regions joyfully demonstrates that the more we learn about the multiform private parts of animals, the more we understand our own unique place in the great diversity of life.

Nature's Path: A History of Naturopathic Healing in America

by Susan E. Cayleff

An eclectic group of firebrands overcame strong odds to create the naturopathic healing system.An alternative medical system emphasizing prevention through healthy living, positive mind-body-spirit strength, and therapeutics to enhance the body’s innate healing processes, naturopathy has gained legitimacy in recent years. In Nature’s Path—the first comprehensive book to examine the complex history and culture of American naturopathy—Susan E. Cayleff tells the fascinating story of the movement’s nineteenth-century roots.While early naturopaths were sometimes divided by infighting, they all believed in the healing properties of water, nutrition, exercise, the sun, and clean, fresh air. Their political activism was vital to their professional formation: they loathed the invasive, depletive practices of traditional medicine and protested against medical procedures that addressed symptoms rather than disease causes while resisting processed foods, pharmaceuticals, environmental toxins, and atomic energy. Cayleff describes the development of naturopathy’s philosophies and therapeutics and details the efforts of its proponents to institutionalize the field. She recognizes notable naturopathic leaders, explores why women doctors, organizers, teachers, and authors played such a strong role in the movement, and identifies countercultural views—such as antivivisection, antivaccination, and vegetarianism—held by idealistic naturopaths from 1896 to the present.Nature’s Path tracks a radical cultural critique, medical system, and way of life that links body, soul, mind, and daily purpose. It is a must-read for historians of medicine and scholars in women’s studies and political history, as well as for naturopaths and all readers interested in alternative medicine.

Nature's Pharmacopeia: A World of Medicinal Plants

by Dan Choffnes

This beautifully illustrated, elegantly written textbook pairs the best research on the biochemical properties and physiological effects of medicinal plants with a fascinating history of their use throughout human civilization, revealing the influence of nature's pharmacopeia on art, war, conquest, and law. By chronicling the ways in which humans have cultivated plant species, extracted their active chemical ingredients, and investigated their effects on the body over time, Nature's Pharmacopeia also builds an unparalleled portrait of these special herbs as they transitioned from wild flora and botanical curiosities to commodities and potent drugs. The book opens with an overview of the use of medicinal plants in the traditional practices and indigenous belief systems of people in the Americas, Africa, Asia, and ancient Europe. It then connects medicinal plants to the growth of scientific medicine in the West. Subsequent chapters cover the regulation of drugs; the use of powerful plant chemicals—such as cocaine, nicotine, and caffeine—in various medical settings; and the application of biomedicine's intellectual frameworks to the manufacture of novel drugs from ancient treatments. Geared toward nonspecialists, this text fosters a deep appreciation of the complex chemistry and cultural resonance of herbal medicine, while suggesting how we may further tap the vast repositories of the world's herbal knowledge to create new pharmaceuticals.

Nature's Restoration: People and Places on the Front Lines of Conservation

by Peter Friederici

Across America and around the world, people areworking to help nature heal itself. In Bermuda, a mansingle-handedly grows thousands of trees on a smallisland to restore nesting habitat for a rare seabird. InIllinois, legions of volunteers replant prairies in theshadows of freeways. In Virginia, a farmer works tobring back the mighty American chestnut.What drives these individuals? How did their passionscome about, and what are the implications forrestoring the environment? Nature"s Restoration: People and Places on theFront Lines of Conservation is a lyrical look at these and other examplesof ordinary citizens aiming to return sizable tracts of the Americanlandscape to nature, and to health. They"ve found success in preservingrare species, reversing negative ecological trends, and promotinggreater intimacy with nature.Yet the work is far from simple. Restoration projects are often in thenews not only because of the promise they hold, but also because ofthe controversy they provoke. Based on detailed reporting and numerousinterviews, Nature"s Restoration puts us on the front lines ofrestoration to learn how this burgeoning national movement shapesboth places and people.

Nature's Services: Societal Dependence On Natural Ecosystems

by Stephen Carpenter Gretchen Daily Les Kaufman Kamaljit Bawa Charles H. Peterson Sandra Postel

Life itself as well as the entire human economy depends on goods and services provided by earth's natural systems. The processes of cleansing, recycling, and renewal, along with goods such as seafood, forage, and timber, are worth many trillions of dollars annually, and nothing could live without them. Yet growing human impacts on the environment are profoundly disrupting the functioning of natural systems and imperiling the delivery of these services.Nature's Services brings together world-renowned scientists from a variety of disciplines to examine the character and value of ecosystem services, the damage that has been done to them, and the consequent implications for human society. Contributors including Paul R. Ehrlich, Donald Kennedy, Pamela A. Matson, Robert Costanza, Gary Paul Nabhan, Jane Lubchenco, Sandra Postel, and Norman Myers present a detailed synthesis of our current understanding of a suite of ecosystem services and a preliminary assessment of their economic value. Chapters consider: major services including climate regulation, soil fertility, pollination, and pest control philosophical and economic issues of valuation case studies of specific ecosystems and services implication of recent findings and steps that must be taken to address the most pressing concerns Nature's Services represents one of the first efforts by scientists to provide an overview of the many benefits and services that nature offers to people and the extent to which we are all vitally dependent on those services. The book enhances our understanding of the value of the natural systems that surround us and can play an essential role in encouraging greater efforts to protect the earth's basic life-support systems before it is too late.

Nature's Temples: The Complex World of Old-Growth Forests

by Joan Maloof

“Maloof eloquently urges us to cherish the wildness of what little old-growth woodlands we have left. . . . Not only are they home to the richest diversity of creatures, but they work hard for humans too.” —New York Times Book Review An old-growth forest is one that has formed naturally over a long period of time with little or no disturbance from humankind. They are increasingly rare and largely misunderstood. In Nature’s Temples, Joan Maloof, the director of the Old-Growth Forest Network, makes a heartfelt and passionate case for their importance. This evocative and accessible narrative defines old-growth and provides a brief history of forests. It offers a rare view into how the life-forms in an ancient, undisturbed forest—including not only its majestic trees but also its insects, plant life, fungi, and mammals—differ from the life-forms in a forest manipulated by humans. What emerges is a portrait of a beautiful, intricate, and fragile ecosystem that now exists only in scattered fragments. Black-and-white illustrations by Andrew Joslin help clarify scientific concepts and capture the beauty of ancient trees.
