This book was released on 2023-02-07 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Pinacate lava fields and expansive dunes to the shores of the Gulf of California, the Gran Desierto is one of the hottest and driest places in the Western Hemisphere. Yet this region in the state of Sonora in northwestern Mexico embraces a remarkable number of habitats with a fascinating and surprisingly rich flora. This is the heart of the Sonoran Desert, still in a largely primordial state, in juxtaposition with the ravished wetlands of the once great Río Colorado. Flora of the Gran Desierto is the culmination of more than twenty-five years of research in this magnificent desert and delta by botanist Richard Felger. This comprehensive floristic study of more than 565 species of vascular plants features original diagnostic descriptions and innovative identification keys to the families, genera, and species. Particular attention has been devoted to taxa that are poorly known. Even weeds and their histories are treated in detail. Hundreds of illustrations by such eminent botanical artists as Lucretia Brezeale Hamilton, Matt Johnson, and Bobbi Angell will aid in the identification of plants. Common names of plants are given in English, Spanish, and O'odham. While emphasizing scientific accuracy, the book is written in an accessible style. Felger's observations and knowledge of plant ecology, geographic distribution, evolution, ethnobotany, plant variation and special adaptations, and the history of the region provides botanists, naturalists, ecologists, conservationists, and anyone else celebrating the desert with readable, interesting, and important information. With two of Mexico's newest biosphere reserves—the Pinacate and the Upper Gulf of California—this region is a keystone for desert conservation efforts. Its location linking vast preserves to the north makes this book especially useful for anyone interested in borderland studies and the Sonoran Desert. Flora of the Gran Desierto represents a most creative, definitive, and enthusiastic treatment of Sonoran Desert plant life and is highly relevant to ecological restoration in deserts and wetlands in arid places worldwide.

This book was released on 2012-12-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following a description of the physical and biological characterization of the four North American deserts together with the primary adaptations of plants to environmental stress, the authors go on to present case studies of key species. They provide an up-to-date and comprehensive review of the major patterns of adaptation in desert plants, with one chapter devoted to several important exotic plants that have invaded these deserts. The whole is rounded off with a synthesis of the resource requirements of desert plants and how they may respond to global climate change.

This book was released on 2015-07-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Botanical Features of North American Deserts Botanical science in its technical and applied branches has reached a stage of development in which it has become plainly evident that adequate progress in research in physiology, in comprehensions of life histories, and in formulating the general principles governing the origin, environic relations and distributional movements of plants may be expected only by experimental methods in the field or in actual contact with the types of plants under consideration under normal environmental conditions. In no part of the subject is this so imperative as in the study of the xerophytic and highly specialized forms characteristic of the desert regions of the world, which comprise a total area equal to that of a large continent. The aridity, widely ranging temperatures of soil and air, physical and chemical properties of the soils, conditions of insolation and radio-activity, together with the special forces modifying distribution, furnish a set of conditions not easily duplicated by the regulation of the artificial climates of glass-houses and not adequately represented by preserved material in herbaria and other collections. A European botanist of ability scarcely lays down his work at the end of a life of zeal and industry devoted to the study of the cacti under cultivation in a climate entirely foreign to them, when an examination of these peculiar forms in their native habitats reveals the necessity for a complete repetition of the entire investigation. When the Carnegie Institution of Washington was established, Mr. Frederick V. Coville determined to present to it a plan for a Desert Botanical Laboratory. This long-cherishcd project was an outcome of his work in the Death Valley Expedition, in 1891. A plan was accordingly drawn up by him and presented to the Institution's Advisory Committee in Botany. This committee considered and approved it because it promised results concerning the fundamental processes of protoplasm as important as any in the whole realm of botany. The Board of Trustees of the Institution also gave their approval to it, and appropriated $8,000 for the establishment of such a laboratory and its maintenance for one year. Messrs. Coville and MacDougal were appointed by the Institution as an Advisory Board in relation to the matter. This Board decided to place the Laboratory under the immediate charge of a resident investigator, who should carry on researches under its guidance, and should be responsible to it in his relations to the Institution.

Available in PDF, EPUB and Kindle. Book excerpt: “Wallace weaves science and mythology into a clear and entertaining story about the origin of California's deserts that invites the reader into a world of ancient mystery and modern revelation. This book will appeal to anyone who cherishes arid lands and their natural history.”-Bruce M. Pavlik, author of The California Deserts: An Ecological Rediscovery “David Rains Wallace explores the origins of the California desert with the endless curiosity of a naturalist, with the wit and wordplay of a fine essayist, and with the attention to detail of a lifelong scholar. He burrows toward the solution of the desert’s riddle by following two centuries of science; in doing so, Wallace writes a unique account of both the ecology of the Desert Southwest and the biologists who have devoted their lives to untangling its evolutionary history.”-Stephen Trimble, author of The Sagebrush Ocean: A Natural History of the Great Basin “David Rains Wallace never fails to truly enter the world of which he writes. Here he tackles fiery heat, ancient lava flows, spiny plants, and scuttling reptiles, all in the service of asking some difficult “how’s” and “why’s.” I learned a lot about places and critters I thought I knew well from this marvelous book.”-Harry Greene, Cornell professor of ecology and evolutionary biology, author of Snakes: the Evolution of Mystery in Nature
