Fully grown they can measure 10 feet and weigh close to 2,000 pounds, but at birth they are just 20 ounces. Creatures that may wander thousands of miles over the course of a year, they begin life in a snowdrift.Human encounters with these legendary beasts are cause for both excitement and apprehension. Tales throughout history describe the ferocity of polar bear attacks on humans; but human hunting of polar bears has exacted a far larger toll, obliging Arctic nations to try to protect their region’s iconic species before it’s too late.Now, however, another threat to the polar bears’ survival has emerged, one that is steadily removing sea ice and the life it supports. Without this habitat, polar bears cannot exist. The Great White Bear celebrates the story of this unique species. Through a blend of history, both natural and human, through myth and reality and observations both personal and scientific, Kieran Mulvaney masterfully provides a context for readers to consider the polar bear, its history, its life, and its uncertain fate.

    This title shows us how to examine, study, and appreciate microbes in the manner of a birdwatcher, by making sightings of microbial activities and thereby identifying particular microbes as well as understanding what they do and how they do it.

    A biography of the Nobel Prize-winning scientist explains her work in genetics and traces her long unheralded career as a research scientist.

    As culturally important foods and medicines, as well as instigators of religious practices, they have been intimately tied to the development and spread of human societies. And yet, despite their numerous influences on the history of the world, fungi are completely disregarded by the majority of people today.In 2006 Peter McCoy founded Radical Mycology, a grassroots organization dedicated to increasing awareness of the many ways to work with fungi for personal, societal, and ecological health. Nearly a decade later, McCoy has written Radical Mycology to share the wide array of skills and insights that have arisen from the organization’s international work to advance the science of appropriately applied mycology. Shattering commonly held beliefs on the value of the Fungal Queendom, Radical Mycology definitively explores the many reasons that fungi should no longer be ignored but instead honored and embraced for the many gifts they offer. The result is the most comprehensive book on mycology—the science of fungi—ever published.Interwoven with short essays on the lessons of the fungi, Radial Mycology begins with chapters that explore the uniqueness of fungal biology, the critical ecological roles of micro and macro fungi, how to accurately identify mushrooms and mycorrhizal fungi, the importance of lichens as medicines and indicators of environmental quality, and the profound influences that fungi have held on the evolution of all life and human cultures. With this foundation laid, the reader is then equipped to work with the fungi directly. Techniques for making potent fungal medicines, growing fermenting fungi for food, and cheaply cultivating mushrooms using recycled tools (and yet still achieving lab-quality results) are explored in-depth. Subsequent chapters grow far beyond the limits of other books on mushrooms. Detailed information on the principles and practices of natural mushroom farming—largely influenced by the design system of permaculture—is presented along with extensive information on cultivating mycorrhizal fungi and the science of mycoremediation, the application of fungi to mitigate pollution in the environment and in our homes. The book ends with deeper insights into the social effects that fungi present from the reflection of mycelial networks in the design of whole societies to a rigorous examination of the history of psychoactive fungi.Written for the beginner as well as the experienced mycologist, Radical Mycology is an invaluable reference book for anyone interested in Do-It-Yourself (or Do-It-Together) homesteading, community organizing, food security, natural medicine, grassroots bioremediation, and the evolution of human-fungal-ecological relations. More than a book on mushrooms, Radical Mycology is a call to ally with the fungi in all efforts to spawn a healthier world. Heavily referenced and vibrantly illustrated by the author, this unprecedented book will undoubtedly remain a classic for generations to come.

    The area immediately next to Luna had already been stripped and, because, as many believed, nothing was left to hold the soil to the mountain, a huge part of the hill had slid into the town of Stafford, wiping out many homes.Over the course of what turned into an historic civil action, Hill endured El Nino storms, helicopter harassment, a ten-day siege by company security guards, and the tremendous sorrow brought about by an old-growth forest's destruction. This story--written while she lived on a tiny platform eighteen stories off the ground--is one that only she can tell.Twenty-five-year-old Julia Butterfly Hill never planned to become what some have called her--the Rosa Parks of the environmental movement. Shenever expected to be honored as one of Good Housekeeping's "Most Admired Women of 1998" and George magazine's "20 Most Interesting Women in Politics," to be featured in People magazine's "25 Most Intriguing People of the Year" issue, or to receive hundreds of letters weekly from young people around the world. Indeed, when she first climbed into Luna, she had no way of knowing the harrowing weather conditions and the attacks on her and her cause. She had no idea of the loneliness she would face or that her feet wouldn't touch ground for more than two years. She couldn't predict the pain of being an eyewitness to the attempted destruction of one of the last ancient redwood forests in the world, nor could she anticipate the immeasurable strength she would gain or the life lessons she would learn from Luna. Although her brave vigil and indomitable spirit have made her a heroine in the eyes of many, Julia's story is a simple, heartening tale of love, conviction, and the profound courage she has summoned to fight for our earth's legacy.

    

    Thomas Pakenham embarks on a five-year odyssey to most of the temperate and tropical regions of the world to photograph sixty trees of remarkable personality and presence: Dwarfs, Giants, Monuments, and Aliens; the lovingly tended midgets of Japan; the enormous strangler from India; and the 4,700-year "Old Methusalehs." American readers will be fascinated by Pakenham's first examination of North American trees, including the towering Redwoods of Sequoia and Yosemite, the gaunt Joshua Trees of Death Valley and the Bristlecone pines discovered in California's White Mountains.Many of these trees were already famous—champions by girth, height, volume or age—while others had never previously been caught by the camera. Pakenham's five-year odyssey, sweating it out with a 30 pound Linhof camera and tripod, took him to most of the temperate and many of the tropical regions of the world. Although North American trees dominate this book, Pakenham also trekked to remote regions in Mexico, all over Europe, parts of Asia including Japan, northern and southern Africa, Madagascar, Australia and New Zealand.Remarkable Trees of the World is a lavish work that will be treasured for generations by all those who marvel at nature.

    The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

    Rural people knew how to prune hazel to foster abundance: both of edible nuts, and of straight, strong, flexible rods for bridges, walls, and baskets. Townspeople cut their beeches to make charcoal to fuel ironworks. Shipwrights shaped oaks to make hulls. No place could prosper without its inhabitants knowing how to cut their trees so they would sprout again.Pruning the trees didn’t destroy them. Rather, it created the healthiest, most sustainable and most diverse woodlands that we have ever known. In this journey from the English fens to Spain, Japan, and California, William Bryant Logan rediscovers what was once an everyday ecology. He offers us both practical knowledge about how to live with trees to mutual benefit and hope that humans may again learn what the persistence and generosity of trees can teach.

    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.

    From New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, she has befriended octopuses with strikingly different personalities—gentle Athena, assertive Octavia, curious Kali, and joyful Karma. Each creature shows her cleverness in myriad ways: escaping enclosures like an orangutan; jetting water to bounce balls; and endlessly tricking companions with multiple “sleights of hand” to get food.Scientists have only recently accepted the intelligence of dogs, birds, and chimpanzees but now are watching octopuses solve problems and are trying to decipher the meaning of the animal’s color-changing techniques. With her “joyful passion for these intelligent and fascinating creatures” (Library Journal Editors’ Spring Pick), Montgomery chronicles the growing appreciation of this mollusk as she tells a unique love story. By turns funny, entertaining, touching, and profound, The Soul of an Octopus reveals what octopuses can teach us about the meeting of two very different minds.

    Herbalist and naturalist Gregory Tilford provides a thorough introduction to the world of herbal medicine for everyone interested in plants, personal well-being, and a healthy environment.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.
