Mountain sheep epitomize wilderness for many people because they occupy some of the most inaccessible and rugged habitats known to man, from desert crags to alpine mountains. But of all hoofed mammals in North America, wild sheep present the greatest management problems to biologists. This book is a major reference on the natural history, ecology, and management of wild sheep in North America. Written by wildlife biologists who have devoted years of study to the animals, it covers Dall's and Stone's sheep and Rocky Mountain, California, and desert bighorn and examines a variety of factors pertinent to their life histories: habitat, diet, activity, social organization, reproduction, and population dynamics. Additional chapters consider distribution and abundance, adaptive strategies, and management guidelines. Discussions on diseases of wild sheep present a wealth of information that will be of particular use to wildlife biologists, including detailed clinical descriptions of conditions that threaten sheep populations, from pasteurellosis to capture myopathy. An appendix reviews the cytogenetics and genetics of wild sheep. North American wild sheep may face extinction in many areas unless critical questions concerning their management are answered soon. Prior to the publication of this book, there was no single reference available in which one could find such a synthesis of information. Mountain Sheep of North America provides that source and points toward the preservation of these magnificent wild creatures.

Founded amid the urban commotion of Washington, DC, before the dawn of the twentieth century, the National Zoological Park opened to “preserve, teach, and conduct research about the animal world.” Entangled Encounters at the National Zoo is a study of this important cultural landmark from 1887 to 1920. Centered on the animals themselves, each chapter looks from a different angle at the influential science of popular zoology in order to shed new light on the complex, entangled relationships between humans and animals. Daniel Vandersommers’s goal is twofold. First, through narrative, he shows how zoo animals always ran away from the zoo. This is meant literally—animals escaped frequently—but even more so, figuratively. Living, breathing, historical zoo animals ran away from their cultural constructions, and these constructions ran away from the living bodies they were made to represent. The author shows that the resulting gaps produced by runaway animals contain concealed, distorted, and erased histories worthy of uncovering. Second, Entangled Encounters at the National Zoo demonstrates how the popular zoology fostered by the National Zoo shaped every aspect of American science, culture, and conservation during the Gilded Age and Progressive Era. Between the 1880s and World War I, as intellectuals debated Darwinism and scientists institutionalized the laboratory, zoological parks suddenly appeared at the heart of nearly every major American city, captivating tens of millions of visitors. Vandersommers follows stories previously hidden within the National Zoo in order to help us reconsider the place of zoos and their inhabitants in the twenty-first century.

Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico’s wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico’s wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.
