For most of us the word "desert" conjures up images of barren wasteland, vast, dry stretches inimical to life. But for a great array of creatures, perhaps even more plentiful than those who inhabit tropical rainforests, the desert is a haven and a home. Travel with Michael Mares into the deserts of Argentina, Iran, Egypt, and the American Southwest and you will encounter a rich and memorable variety of these small, tenacious animals, many of them first discovered by Mares in areas never before studied. Accompanying Mares on his forays into these hostile habitats, we observe the remarkable behavioral, physiological, and ecological adaptations that have allowed such little-known species of rodents, bats, and other small mammals to persist in an arid world. At the same time, we see firsthand the perils and pitfalls that await biologists who venture into the field to investigate new habitats, discover new species, and add to our knowledge of the diversity of life.

Filled with the seductions and trials that such adventures entail, A Desert Calling affords an intimate understanding of the biologist's vocation. As he astonishes us with the range and variety of knowledge to be acquired through the determined investigation of little-known habitats, Mares opens a window on his own uncommon life, as well as on the uncommon life of the remote and mysterious corners of our planet.

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.
