Scientists and conservationists are beginning to understand the importance of top carnivores to the health and integrity of fully functioning ecosystems. As burgeoning human populations continue to impinge on natural landscapes, the need for understanding carnivore populations and how we affect them is becoming increasingly acute.Desert Puma represents one of the most detailed assessments ever produced of the biology and ecology of a top carnivore. The husband-and-wife team of Kenneth Logan and Linda Sweanor set forth extensive data gathered from their ten-year field study of pumas in the Chihuahua Desert of New Mexico, also drawing on other reliable scientific data gathered throughout the puma's geographic range. Chapters examine: the evolutionary and modern history of pumas, their taxonomy, and physical description a detailed description and history of the study area in the Chihuahua Desert field techniques that were used in the research puma population dynamics and life history strategies the implications of puma behavior and social organization the relationships of pumas and their preyThe authors provide important new information about both the biology of pumas and their evolutionary ecology -- not only what pumas do, but why they do it. Logan and Sweanor explain how an understanding of puma evolutionary ecology can, and must, inform long-term conservation strategies. They end the book with their ideas regarding strategies for puma management and conservation, along with a consideration of the future of pumas and humans. Desert Puma makes a significant and original contribution to the science not only of pumas in desert ecosystems but of the role of top predators in all environments. It is an essential contribution to the bookshelf of any wildlife biologist or conservationist involved in large-scale land management or wildlife management.

A story of indomitable spirit. A journey of ancestral discovery. Set against the backdrop of the most inhospitable desert on the planet, two young women from different worlds forge a link that transcends time. Mia Chavez, a young Australian archaeologist, arrives in Chile to connect with her familial origins. Startling events unfold as she unearths dramatic links to the flight for the life of an Atacameños girl, Kiki, five centuries previously. Hunted by the malevolent shaman, Mamut, Kiki’s escape within the ancient mountains of the Andes, inexorably lure Mia to uncover a mystery beyond belief.

The United States and MexicoÕs shared environment extends far beyond the political line. For instance, it comprises the plant and animal species whose natural distributions extend deep into each nation along with the waters in rivers and aquifers that support ecosystem function far removed from the border. Conservation of Shared Environments presents a broad perspective on the ecological, social and political challenges of conserving biodiversity across the U.S.-Mexico border. Covering topics as diverse as wildlife and grassland preservation, water rights, ecosystem services, indigenous peoples, and the ecological consequences of border security, the contributors illustrate collaborative, transboundary efforts to overcome cross-border conservation challenges. This volume offers scientific analysis as well as insight for bridging gaps between researchers, policymakers, and the public.

Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.
