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 R’o 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.

Farming across Borders uses agricultural history to connect the regional experiences of the American West, northern Mexico, western Canada, and the North American side of the Pacific Rim, now writ large into a broad history of the North American West. Case studies of commodity production and distribution, trans-border agricultural labor, and environmental change unite to reveal new perspectives on a historiography traditionally limited to a regional approach. Sterling Evans has curated nineteen essays to explore the contours of “big” agricultural history. Crops and commodities discussed include wheat, cattle, citrus, pecans, chiles, tomatoes, sugar beets, hops, henequen, and more. Toiling over such crops, of course, were the people of the North American West, and as such, the contributing authors investigate the role of agricultural labor, from braceros and Hutterites to women working in the sorghum fields and countless other groups in between. As Evans concludes, “society as a whole (no matter in what country) often ignores the role of agriculture in the past and the present.” Farming across Borders takes an important step toward cultivating awareness and understanding of the agricultural, economic, and environmental connections that loom over the North American West regardless of lines on a map. In the words of one essay, “we are tied together . . . in a hundred different ways.”

More often than not, when people think of a neotropical forest, what comes to mind is a rain forest, rather than a dry forest. Just as typically, when they imagine a savanna, they visualize the African plains, rather than those dry woodlands and grasslands found in the Neotropics. These same preconceptions can be found among scientists, as these neotropical biomes receive nowhere near the attention they should - in terms of both research and conservation -considering the amount of land they encompass and the diversity of vegetation they contain. Neotropical Savannas and Dry Forests: Plant Diversity, Biogeography, and Conservation provides an engaging synthesis of information on the plant diversity and geography, as well as the conservation status, of these species-rich areas. This impressive compilation is the result of a plant diversity symposium that took place during an international conference on tropical savannas and seasonally dry forests held in 2003. Fifty leading scientists, representing a variety of disciplines have contributed to the chapters of this book in an effort to address three questions: What are the patterns of diversity, species-richness and endemism of the floras of neotropical seasonally dry forest and savannas? How and why did this endemism and diversity arise? Are these ecosystems adequately protected and, if not, which areas should be elevated into priorities for conservation, and how can this be best achieved? This work is the first extensive compilation of the patterns of plant biodiversity in these neotropical ecosystems. The overview also provides a summary of what is known of their evolutionary history, including an examination of the links to the development of analogous vegetation in Africa. In contrast to previously published titles that emphasize ecology and physiology, this work focuses on plant biodiversity and reviews molecular phylogenetic and molecular population genetic approaches to discovering biogeographic history.

The future of our food depends on tiny seeds in orchards and fields the world over. In 1943, one of the first to recognize this fact, the great botanist Nikolay Vavilov, lay dying of starvation in a Soviet prison. But in the years before Stalin jailed him as a scapegoat for the country’s famines, Vavilov had traveled over five continents, collecting hundreds of thousands of seeds in an effort to outline the ancient centers of agricultural diversity and guard against widespread hunger. Now, another remarkable scientist—and vivid storyteller—has retraced his footsteps. In Where Our Food Comes From, Gary Paul Nabhan weaves together Vavilov’s extraordinary story with his own expeditions to Earth’s richest agricultural landscapes and the cultures that tend them. Retracing Vavilov’s path from Mexico and the Colombian Amazon to the glaciers of the Pamirs in Tajikistan, he draws a vibrant portrait of changes that have occurred since Vavilov’s time and why they matter. In his travels, Nabhan shows how climate change, free trade policies, genetic engineering, and loss of traditional knowledge are threatening our food supply. Through discussions with local farmers, visits to local outdoor markets, and comparison of his own observations in eleven countries to those recorded in Vavilov’s journals and photos, Nabhan reveals just how much diversity has already been lost. But he also shows what resilient farmers and scientists in many regions are doing to save the remaining living riches of our world. It is a cruel irony that Vavilov, a man who spent his life working to foster nutrition, ultimately died from lack of it. In telling his story, Where Our Food Comes From brings to life the intricate relationships among culture, politics, the land, and the future of the world’s food.

This report is the result of a cooperative effort by the Rocky Mountain Research Station and the USDA Forest Service Region 3, with participation by the Arizona Game and Fish Department and the Bureau of Land Management. It assesses the state of knowledge related to the conservation status of the cactus ferruginous pygmy-owl in Arizona. The population decline of this owl has been attributed to the loss of riparian areas before and after the turn of the 20th century. Currently, the cactus ferruginous pygmy-owl is chiefly found in southern Arizona in xeroriparian vegetation and wellstructured upland desertscrub. The primary threat to the remaining pygmy-owl population appears to be continued habitat loss due to residential development. Important information gaps exist and prevent a full understanding of the current population status of the owl and its conservation needs.

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.

In Rio de Janeiro in June 1992 a new International Convention on the Conservation of Biological Diversity was signed whereby each country accepts a responsibility to safe guard its own natural diversity and to cooperate internationally. The Centres of Plant Diversity project has involved over 400 botanists, conservationists and resource managers worldwide, together with over 100 collaborating institutions and organizations, and has been co-ordinated by the IUCN Plant Conservation Office at Kew, UK. A standard format has been adopted for each of the regional overviews and data sheets.

Gentry's R’o Mayo Plants

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.
