After all, we ourselves are the product of evolution, and we can tackle many of our gravest challenges –– from lethal resurgence of antiobiotic–resistant diseases to the wave of extinctions that looms before us –– with a sound understanding of the science.

    Each portrait includes full-color original artwork; details on identification, habitat, nesting, and food; and a color-coded range map.

    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.

    From the Sierra Nevada, the Mojave Desert, the Yucatan Peninsula, and the Bahamas to her home ground on the high plateaus and deep canyons of the Southwest, we journey with Meloy through vistas of both great beauty and great desecration. Her keen vision makes us look anew at ancestral mountains, turquoise seas, and even motel swimming pools. She introduces us to Navajo “velvet grandmothers” whose attire and aesthetics absorb the vivid palette of their homeland, as well as to Persians who consider turquoise the life-saving equivalent of a bullet-proof vest. Throughout, Meloy invites us to appreciate along with her the endless surprises in all of life and celebrates the seduction to be found in our visual surroundings.

    McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever. McKibben writes of our earth's environmental cataclysm, addressing such core issues as the greenhouse effect, acid rain, and the depletion of the ozone layer. His new introduction addresses some of the latest environmental issues that have risen during the 1990s. The book also includes an invaluable new appendix of facts and figures that surveys the progress of the environmental movement.More than simply a handbook for survival or a doomsday catalog of scientific prediction, this classic, soulful lament on Nature is required reading for nature enthusiasts, activists, and concerned citizens alike.

    Tom Brown was taught the ancient skills of survival by a Native American he called Grandfather. His most advanced lessons were those of the scouts, members of a secret society who were highly attuned to nature. The scouts refined tracking to a disciplined science and art form. With these physical skills came enhanced perception and true enlightment. "Tracking was their doorway to the universe," Tom Brown writes, "where they could know all things through the tracks..."Now Tom Brown, Jr. shares generations of wisdom through one of the most rewarding pursuits to be found in nature. Tracking lets us unlock the secrets of each animal we follow, and in turn, to become more aware of our own place in nature and the world. It is a journey of discovery that engages the senses, awakens the spirit, and enlightens the soul.

    These adorable, furry marine mammals--often seen floating on their backs holding hands--reveal the health of the coastal ecosystem along the Pacific Ocean. Once hunted for their prized fur during the 1700s and 1800s, these animals nearly went extinct. Only now, nearly a century after hunting ceased, are populations showing stable growth in some places. Sea otters are a keystone species in coastal areas, feeding on sea urchins, clams, crab, and other crustaceans. When they are present, kelp beds are thick and healthy, providing homes for an array of sealife. When otters disappear, sea urchins take over, and the kelp disappears along with all of the creatures that live in the beds. Now, thanks to their protected status, sea otters are floating around in coves in California, Washington, and Alaska.Todd McLeish is a science writer with three published books, all on natural history topics: Narwhals, Basking with Humpbacks, and Golden Wings and Hairy Toes: New England Wildlife. He is a popular public speaker on cruise ships and at museums and environmental centers and has published articles on wildlife topics in Earthwatch Journal, Bird Watcher's Digest, WildBird, and Natural New England, among other publications.

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    Honey bees, and the daily workings of their close-knit colonies, are one of nature's great miracles. And they produce one of nature's greatest edible bounties: honey. More than just a palate pleaser, honey was once an offering to the gods, a preservative, and a medicine whose sought-after curative powers were detailed in ancient texts . . . and are being rediscovered by modern medical science.In Letters from the Hive, Prof. Stephen Buchmann takes us into the hive--nursery, honey factory, queen's inner sanctum--and out to the world of backyard gardens, open fields, and deserts in full bloom, where the age-old sexual dance between flowers and bees makes life on earth as we know it possible. Hailed for their hard work, harmonious society, and, mistakenly, for their celibacy, bees have a link to our species that goes beyond biology. In Letters from the Hive, Buchmann explores the fascinating role of bees in human culture and mythology, following the "honey hunters" of native cultures in Malaysia, the Himalayas, and the Australian Outback as they risk life and limb to locate a treasure as valuable as any gold.To contemplate a world without bees is to imagine a desolate place, culturally and biologically, and Buchmann shows how with each acre of land sacrificed to plow, parking lot, or shopping mall, we inch closer to what could become a chilling reality. He also offers honey-based recipes, cooking tips, and home remedies--further evidence of the gifts these creatures have bestowed on us.Told with wit, wisdom, and affection, and rich with anecdote and science, Letters from the Hive is nature writing at its best. This is natural history to be treasured, a sweet tribute that buzzes with life.From the Hardcover edition.

    But, after a broken engagement and a broken heart, he desperately needed a change of scenery. The ambitious plan he cooked up went a bit overboard in that department; Knighton set out to visit every single one of America's National Parks, from Acadia to Zion. Leave Only Footprints is the memoir of his year spent traveling across the United States, a journey that yielded his "On the Trail" series, which quickly became one of CBS Sunday Morning's most beloved segments. In this smart, informative, and often hilarious book, he'll share how his journey through these natural wonders, unchanged by man, ended up changing his worldview on everything from God to politics to love and technology. Whether it's waking up early for a naked scrub in an Arkansas bathhouse or staying up late to stargaze along our loneliest highway, Knighton goes behind the scenery to provide an unfiltered look at America. In the tradition of books like A Walk in the Woods or Turn Right at Machu Picchu, this is an irresistible mix of personal narrative and travelogue-some well-placed pop culture references, too-and a must-read for any of the 331 million yearly National Parks visitors.

    In Otherlands, Halliday makes sixteen fossil sites burst to life on the page.This book is an exploration of the Earth as it used to exist, the changes that have occurred during its history, and the ways that life has found to adapt―or not. It takes us from the savannahs of Pliocene Kenya to watch a python chase a group of australopithecines into an acacia tree; to a cliff overlooking the salt pans of the empty basin of what will be the Mediterranean Sea just as water from the Miocene Atlantic Ocean spills in; into the tropical forests of Eocene Antarctica; and under the shallow pools of Ediacaran Australia, where we glimpse the first microbial life.Otherlands also offers us a vast perspective on the current state of the planet. The thought that something as vast as the Great Barrier Reef, for example, with all its vibrant diversity, might one day soon be gone sounds improbable. But the fossil record shows us that this sort of wholesale change is not only possible but has repeatedly happened throughout Earth history.Even as he operates on this broad canvas, Halliday brings us up close to the intricate relationships that defined these lost worlds. In novelistic prose that belies the breadth of his research, he illustrates how ecosystems are formed; how species die out and are replaced; and how species migrate, adapt, and collaborate. It is a breathtaking achievement: a surprisingly emotional narrative about the persistence of life, the fragility of seemingly permanent ecosystems, and the scope of deep time, all of which have something to tell us about our current crisis.
