    Belknap's Waterproof Grand Canyon River Guide (All New Color Edition)

    So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world’s foremost arbornauts, known as the “real-life Lorax.” She planned one of the first treetop walkways and helps create more of these bridges through the eighth continent all over the world.With a voice as infectious in its enthusiasm as it is practical in its optimism, The Arbornaut chronicles Lowman’s irresistible story. From climbing solo hundreds of feet into the air in Australia’s rainforests to measuring tree growth in the northeastern United States, from searching the redwoods of the Pacific coast for new life to studying leaf eaters in Scotland’s Highlands, from conducting a BioBlitz in Malaysia to conservation planning in India and collaborating with priests to save Ethiopia’s last forests, Lowman launches us into the life and work of a field scientist, ecologist, and conservationist. She offers hope, specific plans, and recommendations for action; despite devastation across the world, through trees, we can still make an immediate and lasting impact against climate change.A blend of memoir and fieldwork account, The Arbornaut gives us the chance to live among scientists and travel the world—even in a hot-air balloon! It is the engrossing, uplifting story of a nerdy tree climber—the only girl at the science fair—who becomes a giant inspiration, a groundbreaking, ground-defying field biologist, and a hero for trees everywhere.Includes black-and-white illustrations

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    As Joel Reynolds launches a legal fight to expose and challenge the Navy program, marine biologist Ken Balcomb witnesses a mysterious mass stranding of whales near his research station in the Bahamas. Investigating this calamity, Balcomb is forced to choose between his conscience and an oath of secrecy he swore to the Navy in his youth.When Balcomb and Reynolds team up to expose the truth behind an epidemic of mass strandings, the stage is set for an epic battle that pits admirals against activists, rogue submarines against weaponized dolphins, and national security against the need to safeguard the ocean environment. Waged in secret military labs and the nation’s highest court, War of the Whales is a real-life thriller that combines the best of legal drama, natural history, and military intrigue.

    More than 2,000 stunning images show these trees in their natural habitats. Other features include: a unique identification tip for each tree; range maps showing distribution in North America; How to Identify a Tree section; a detailed glossary of tree parts and leaf, fruit, flower, and bark types; essays on ecology, conservation, and North America’s important forest types; plus a complex species and quick-flip indexes. The guide’s unique waterproof cover makes it especially valuable for use in the field.

    Mt. Lockley, who observed rabbits in Wales over a 5 year period, shows that they have a complex community life little understood by the world in general. These vegetarian creatures posses both dignity and 'animality'; psychological factors play as large a part in shaping their lives as they do in ours. One finds, too, that their reputation for promiscuity and wanton reproduction is really undeserved. Lockley built an artificial warren with glass sides and several tracts of natural habitat-an open plain, a woodlot, a lushly vegetated savannah were enclosed and arranged for maximum ease of observation with minimum interference. This controlled rabbit colony was observed every day and night in every season and in all kinds of weather. In Lockley's account, rabbits emerge with characteristics and personalities of their own. The nicknames he gives them (Weary Willie, Timid Timothy, Bold Benjamin, for example) in no way lessen the objective and scientific accuracy of his findings. In fact, this touch of individuality reinforces the observation that rabbits are creatures with interests, wills, and preferences of their own. Female conservatism, scent setting or 'chinning' by dominant males, the ability of the female to absorb her fertilized embryo, the stress of subordinate status...and more, are revealed here.

    Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.

    Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower.- A dichotomous key to all the species described in the book is designed to narrow the choices to a few possible species. Identification can then be confirmed by reading the descriptions of the species and comparing a specimen with the drawings and photographs.- A fold-out grass identification table provides diagnostic information for weedy grasses in an easy-to-use tabular key.- Specimens with unusual vegetative characteristics, such as thorns, square stems, whorled leaves, or milky sap, can be rapidly identified using the shortcut identification table.The first comprehensive weed identification manual available for the Northeast, this book will facilitate appropriate weed management strategy in any horticultural or agronomic cropping system and will also serve home gardeners and landscape managers, as well as pest management specialists and allergists.

    Experienced birders use the most easily observed characteristics — size, structure, behavior, and general color patterns — to identify birds even before looking carefully at plumage details. Now birders at all levels can learn how to identify shorebirds quickly and simply. This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the bird throughout its life cycle. Quiz questions in the captions will engage and challenge all birders and help them benefit from this simplified, commonsense approach to identification.

    This volume highlights the research and findings of this natural scientist. Powerful modern microscopes have confirmed the accuracy of Haeckel's prints, which even in their day, became world famous. Haeckel's portfolio, first published between 1899 and 1904 in separate installments, is described in the opening essays. The plates illustrate Haeckel's fundamental monistic notion of the -unity of all living things- and the wide variety of forms are executed with utmost delicacy. Incipient microscopic organisms are juxtaposed with highly developed plants and animals. The pages, ordered according to geometric and -constructive- aspects, document the oness of the world in its most diversified forms. This collection of plates was not only well-received by scientists, but by artists and architects as well. Rene Binet, a pioneer of glass and iron constructions, Emile Galle, a renowned Art Nouveau designer, and the photographer Karl Blossfeld all make explicit reference to Haeckel in their work.

    This book is, like its author, a unique achievement. Weaving a vivid portrait of her own life and her bees' lives through the seasons, Hubbell writes "about bees to be sure, but also about other things: the important difference between loneliness and solitude . . . the accommodating of oneself to nature" (Philadelphia Inquirer).

    Volume I lays out the vision of the forest garden and explains the basic ecological principles that make it work. In Volume II, Dave Jacke and Eric Toensmeier move on to practical considerations: concrete ways to design, establish, and maintain your own forest garden. Along the way they present case studies and examples, as well as tables, illustrations, and a uniquely valuable -plant matrix- that lists hundreds of the best edible and useful species.Taken together, the two volumes of Edible Forest Gardens offer an advanced course in ecological gardening--one that will forever change the way you look at plants and your environment.
