"A Natural History of the Sonoran Desert provides the most complete collection of Sonoran Desert natural history information ever compiled and is a perfect introduction to this biologically rich desert of North America."--BOOK JACKET.

This book offers an accessible introduction to Sonoran Desert ecology. Eight original essays by Sonoran Desert specialists provide an overview of the practice of ecology at landscape, community, and organism levels. The essays explore the rich diversity of plant life in the Sonoran Desert and the ecological patterns and processes that underlie it. They also reveal the history and scientific legacy of the Desert Laboratory in Tucson, which has conducted research on the Sonoran Desert since 1903.

The Sonoran Desert, a fragile ecosystem, is under ever-increasing pressure from a burgeoning human population. This ecological atlas of the region's plants, a greatly enlarged and full revised version of the original 1972 atlas, will be an invaluable resource for plant ecologists, botanists, geographers, and other scientists, and for all with a serious interest in living with and protecting a unique natural southwestern heritage. An encyclopedia as well as an atlas, this monumental work describes the taxonomy, geographic distribution, and ecology of 339 plants, most of them common and characteristic trees, shrubs, or succulants. Also included is valuable information on natural history and ethnobotanical, commercial, and horticultural uses of these plants. The entry for each species includes a range map, an elevational profile, and a narrative account. The authors also include an extensive bibliography, referring the reader to the latest research and numerous references of historical importance, with a glossary to aid the general reader. Sonoran Desert Plants is a monumental work, unlikely to be superseded in the next generation. As the region continues to attract more people, there will be an increasingly urgent need for basic knowledge of plant species as a guide for creative and sustainable habitation of the area. This book will stand as a landmark resource for many years to come.

Although possessing a common physical heritage, the Sonoran Desert has taken on highly contrasting forms in its American and Mexican portions. This work does not, therefore, attempt a regional study in the usual sense of the term, but is rather an examination of disparate economic development, much influenced by contrasting technological achievements as well as the accidents of history. Although the significance of geographic regionalism is implicit throughout this study, no attempt is made to show any overriding unity at work, geographical or otherwise, welding together a "desert region." Instead the desert acts as a stage for social drama in which drought and extreme heat provide the essential backcloth. The scarcity of water and man's inability to grow crops without irrigation have not, indeed, changed with time, and only constant reference to this immutable factor can give meaning to the evolution of human activities within the desert.

The saguaro, with its great size and characteristic shape—its arms stretching heavenward, its silhouette often resembling a human—has become the emblem of the Sonoran Desert of southwestern Arizona and northwestern Mexico. The largest and tallest cactus in the United States, it is both familiar and an object of fascination and curiosity. This book offers a complete natural history of this enduring and iconic desert plant. Gathering everything from the saguaro’s role in Sonoran Desert ecology to its adaptations to the desert climate and its sacred place in Indigenous culture, this book shares precolonial through current scientific findings. The saguaro is charismatic and readily accessible but also decidedly different from other desert flora. The essays in this book bear witness to our ongoing fascination with the great cactus and the plant’s unusual characteristics, covering the saguaro’s: history of discovery, place in the cactus family, ecology, anatomy and physiology, genetics, and ethnobotany. The Saguaro Cactus offers testimony to the cactus’s prominence as a symbol, the perceptions it inspires, its role in human society, and its importance in desert ecology.

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.

High above the noise and traffic of metropolitan Phoenix, Native American rock art offers mute testimony that another civilization once thrived in the Arizona desert. In the city's South Mountains, prehispanic peoples pecked thousands of images into the mountains' boulders and outcroppings—images that today's hikers can encounter with every bend in the trail. Todd Bostwick, an archaeologist who has studied the Hohokam for more than twenty years, and Peter Krocek, a professional photographer with a passion for archaeology, have combed the South Mountains to locate nearly all of the ancient petroglyphs found in the canyons and ridges. Their years of learning the landscape and investigating the ancient designs have resulted in a book that explores this wealth of prehistoric rock art within its natural and cultural contexts, revealing what these carvings might mean, how they got there, and when they were made. Landscape of the Spirits is the first book to cover these ancient images and is one of the most comprehensive treatments of a rock art location ever published. It conveys the range of different rock art elements and compositions found in the South Mountains—animals, humans, and geometric shapes, as well as celestial and calendrical markings at key sites—through accurate descriptions, drawings, and photographs. Interpretations of the petroglyphs are based on Native American ethnographic accounts and consider the most recent theories concerning shamanism and archaeoastronomy. Written in a simple and accessible style, Landscape of the Spirits is an indispensable volume for anyone exploring the South Mountains, and for rock art enthusiasts everywhere who wish to broaden their understanding of the prehistoric world. It is both an authoritative overview of these ancient wonders and an unprecedented benchmark in southwestern rock art research at a single geographic location.

Part natural history, part call to conservation, and part love song, this evocative and informative excursion into the Sonoran Desert along the U.S.-Mexico border brings to life the beauty of a sparse and seductive terrain.

In the darkness of the star-studded desert, bats and moths feed on the nectar of night-blooming cactus flowers. By day, birds and bees do the same, taking to blooms for their sweet sustenance. In return these special creatures pollinate the equally intriguing plants in an ecological circle of sustainability. The Sonoran Desert is the most biologically diverse desert in the world. Four species of columnar cacti, including the iconic saguaro and organ pipe, are among its most conspicuous plants. No Species Is an Island describes Theodore H. Fleming’s eleven-year study of the pollination biology of these species at a site he named Tortilla Flats in Sonora, Mexico, near Kino Bay. Now Fleming shares the surprising results of his intriguing work. Among the novel findings are one of the world’s rarest plant-breeding systems in a giant cactus; the ability of the organ pipe cactus to produce fruit with another species’ pollen; the highly specialized moth-cactus pollination system of the senita cactus; and the amazing lifestyle of the lesser long-nosed bat, the major nocturnal pollinator of three of these species. These discoveries serve as a primer on how to conduct ecological research, and they offer important conservation lessons for us all. Fleming highlights the preciousness of the ecological web of our planet—Tortilla Flats is a place where cacti and migratory bats and birds connect such far-flung habitats as Mexico’s tropical dry forest, the Sonoran Desert, and the temperate rain forests of southeastern Alaska. Fleming offers an insightful look at how field ecologists work and at the often big surprises that come from looking carefully at a natural world where no species stands alone.
