Only a day's drive south of the U.S.-Mexico border, a tropical deciduous forest opens up a world of exotic trees and birds that most people associate with tropical forests of more southerly latitudes. Like many such forests around the world, this diverse ecosystem is highly threatened, especially by large-scale agricultural interests that are razing it in order to plant grass for cattle. This book introduces the tropical deciduous forest of the Alamos region of Sonora, describing its biodiversity and the current threats to its existence. The book's contributors present the most up-to-date scientific knowledge of this threatened ecosystem. They review the natural history and ecology of its flora and fauna and explore how native peoples use the forest's many resources. Included in the book's coverage is a comprehensive plant list for the Río Cuchujaqui area that well illustrates the diversity of the forest. Other contributions examine tree species used by Mayo Indians and the numerous varieties of domesticated plants that have been developed over the centuries by the Mayos and other indigenous peoples. Also examined are the diversity and distribution of reptiles, amphibians, mammals, and birds in the region. The Tropical Deciduous Forest of Alamos provides critical information about a globally important biome. It complements other studies of similar forests and allows a better understanding of a diverse but vanishing ecosystem.

This volume in the Greenwood Guides to Biomes of the World series covers the lush, beautiful - and rapidly shrinking - tropical forest biomes. The volume covers the two major tropic forest biomes, tropical rainforests and tropical seasonal forests.

The Río Mayo region of northwestern Mexico is a major geographic area whose natural history remains poorly known to outsiders. Lying in a region where desert and tropical, northern and southern, and continental and coastal species converge, it boasts an abundance of flora first documented by Howard Scott Gentry in 1942 in a book now widely regarded as a classic of botanical literature. This new book updates and amends Gentry's Río Mayo Plants. Undertaken with Gentry's support and participation before his death in 1993, it reproduces the original text, which appears here with annotations, and contains information on over 2,800 taxa—more than twice the 1,200 species first described by Gentry. The annotated list of plants includes information on distribution, habitat, appearance, common names, and indigenous uses. A new introduction provides historical background and a review of geography and vegetation. It also describes changes to the land and river wrought by agricultural development, expanded grazing, and lumbering. Throughout the text, the authors have endeavored to provide information on Río Mayo vegetation while emphasizing local knowledge and use of plants, to preserve Gentry's field-oriented focus, and to present botanical information with Gentry's exuberance and style. Río Mayo Plants has long stood as a book that displays a scientist's love of the English language, his fondness for native peoples, and his eye for beauty in nature. This updating of that work fills a gap in the botanical literature of this portion of North America and will be useful not only for botanists but also for biogeographers, taxonomists, land managers, and conservationists.

"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.

One of the most recognizable animals of the Southwest, the desert tortoise (Gopherus agassizii) makes its home in both the Sonoran and Mohave Deserts, as well as in tropical areas to the south in Mexico. Called by Tohono O'odham people "komik'c-ed," or "shell with living thing inside," it is one of the few desert creatures kept as a domestic pet—as well as one of the most studied reptiles in the world. Most of our knowledge of desert tortoises comes from studies of Mohave Desert populations in California and Nevada. However, the ecology, physiology, and behavior of these northern populations are quite different from those of their southern, Sonoran Desert, and tropical cousins, which have been studied much less. Differences in climate and habitat have shaped the evolution of three races of desert tortoises as they have adapted to changes in heat, rainfall, and sources of food and shelter as the deserts developed in the last ten million years. This book presents the first comprehensive summary of the natural history, biology, and conservation of the Sonoran and Sinaloan desert tortoises, reviewing the current state of knowledge of these creatures with appropriate comparisons to Mohave tortoises. It condenses a vast amount of information on population ecology, activity, and behavior based on decades of studying tortoise populations in Arizona and Sonora, Mexico, and also includes important material on the care and protection of tortoises. Thirty-two contributors address such topics as tortoise fossil records, DNA analysis, and the mystery of secretive hatchlings and juveniles. Tortoise health is discussed in chapters on the care of captives, and original data are presented on the diets of wild and captive tortoises, the nutrient content of plant foods, and blood parameters of healthy tortoises. Coverage of conservation issues includes husbandry methods for captive tortoises, an overview of protective measures, and an evaluation of threats to tortoises from introduced grass and wildfires. A final chapter on cultural knowledge presents stories and songs from indigenous peoples and explores their understanding of tortoises. As the only comprehensive book on the desert tortoise, this volume gathers a vast amount of information for scientists, veterinarians, and resource managers while also remaining useful to general readers who keep desert tortoises as backyard pets. It will stand as an enduring reference on this endearing creature for years to come.

The definitive treatment of the trees and tree-like plants of Sonora, a remarkably diverse and biologically important region, ranging from some of the driest and hottest areas in North America to cool, temperate woodlands and the northernmost tropical regions in the New World. The majority of the trees in this semi-arid region are at their northern limits in the Americas in this state and many range to South America. Thus, this book will be important to biologists in regions well outside of the area covered. Felger is the recognized expert in the area, and the book contains an enormous body of information nowhere else obtainable. The introductory chapter contains biotic and climatic information and an analysis of the geographical distributions of the trees of a state that is poorly known biologically. Two hundred eighty-five species of native and naturalized trees are covered, featuring extensive identification keys and illustrations, most of them newly produced for this book. The descriptive species accounts include common names, indigenous names, and synonyms, detailed botanical descriptions, ecological and geographic data, geographic ranges, natural history, economic uses, and, in many cases, other information such as horticultural uses and conservation status.
