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 petÑas 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.

All over the planet, organisms of many species are appearing outside of their natural habitats—often carried by that particularly peripatetic species Homo sapiens. This book marks the first comprehensive attempt to address problems posed by expanding populations of exotic plant and animal species in the Sonoran Desert and adjacent grasslands and riparian areas. It describes the arrival and spread of non-native species as diverse as rats and saltcedar, covering both their impacts and the management of those impacts. It is estimated that as much as 60 percent of the vegetative cover of the Sonoita Creek-Patagonia Reserve, the first Nature Conservancy area designated in Arizona, is dominated by exotic plants, and that introduced fish pose a recurrent threat to the native fish of that area. Meanwhile at the Grand Canyon, invasives such as tamarisk, red brome, carp, and catfish are pervasive either in the Colorado River or in the patches of desert scrub along its shores. Throughout the Sonoran Desert and adjacent areas, from islands in the Sea of Cortés to desert grasslands, some six hundred species of non-native plants and animals have become established, with bullfrogs and Mediterranean grasses now common where they once never existed. The book brings together contributors from academia, government, and nonprofit organizations, including such experts as Gary Paul Nabhan, Richard Mack, and Alberto Búrquez-Montijo. They review historic and even prehistoric origins of non-native species—not only exotic plants, amphibians, and mammals but also insects, fish, and birds. They then examine significant problems in each major subregion and ecosystem and discuss control efforts. The volume contains the first compiled list of more than 500 naturalized exotic species in the Sonoran region. Invasive species issues are rapidly emerging as major environmental concerns both locally and worldwide. This book will assist professionals—ecologists, conservation biologists, and policy makers—involved in invasive species control in the Southwest and will be a rich resource for all concerned with protecting native species and their habitats.

The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.

Winner of the Alfred B. Thomas Award and sponsored by the Southeastern Council of Latin American Studies, Revolutionary Parks tells the surprising story of how forty national parks were created in Mexico during the latter stages of the first social revolution of the twentieth century. By 1940 Mexico had more national parks than any other country. Together they protected more than two million acres of land in fourteen states. Even more remarkable, Lázaro Cárdenas, president of Mexico in the 1930s, began to promote concepts akin to sustainable development and ecotourism. Conventional wisdom indicates that tropical and post-colonial countries, especially in the early twentieth century, have seldom had the ability or the ambition to protect nature on a national scale. It is also unusual for any country to make conservation a political priority in the middle of major reforms after a revolution. What emerges in Emily Wakild’s deft inquiry is the story of a nature protection program that takes into account the history, society, and culture of the times. Wakild employs case studies of four parks to show how the revolutionary momentum coalesced to create early environmentalism in Mexico. According to Wakild, Mexico’s national parks were the outgrowth of revolutionary affinities for both rational science and social justice. Yet, rather than reserves set aside solely for ecology or politics, rural people continued to inhabit these landscapes and use them for a range of activities, from growing crops to producing charcoal. Sympathy for rural people tempered the radicalism of scientific conservationists. This fine balance between recognizing the morally valuable, if not always economically profitable, work of rural people and designing a revolutionary state that respected ecological limits proved to be a radical episode of government foresight.

Many national parks and monuments tell unique stories of the struggle between the rights of native peoples and the wants of the dominant society. These stories involve our greatest parks—Yosemite, Yellowstone, Mesa Verde, Glacier, the Grand Canyon, Olympic, Everglades—as well as less celebrated parks elsewhere. In American Indians and National Parks, authors Robert Keller and Michael Turek relate these untold tales of conflict and collaboration. American Indians and National Parks details specific relationships between native peoples and national parks, including land claims, hunting rights, craft sales, cultural interpretation, sacred sites, disposition of cultural artifacts, entrance fees, dams, tourism promotion, water rights, and assistance to tribal parks. Beginning with a historical account of Yosemite and Yellowstone, American Indians and National Parks reveals how the creation of the two oldest parks affected native peoples and set a pattern for the century to follow. Keller and Turek examine the evolution of federal policies toward land preservation and explore provocative issues surrounding park/Indian relations. When has the National Park Service changed its policies and attitudes toward Indian tribes, and why? How have environmental organizations reacted when native demands, such as those of the Havasupai over land claims in the Grand Canyon, seem to threaten a national park? How has the Park Service dealt with native claims to hunting and fishing rights in Glacier, Olympic, and the Everglades? While investigating such questions, the authors traveled extensively in national parks and conducted over 200 interviews with Native Americans, environmentalists, park rangers, and politicians. They meticulously researched materials in archives and libraries, assembling a rich collection of case studies ranging from the 19th century to the present. In American Indians and National Parks, Keller and Turek tackle a significant and complicated subject for the first time, presenting a balanced and detailed account of the Native-American/national-park drama. This book will prove to be an invaluable resource for policymakers, conservationists, historians, park visitors, and others who are concerned about preserving both cultural and natural resources.
