Paul A. Johnsgard is Foundation Regents Professor Emeritus in the School of Biological Sciences at the University of Nebraska-Lincoln. He is the winner of the 2004 National Conservation Achievement Award and recipient of the Lifetime Achievement Award, both sponsored by the National Wildlife Federation, and the author of more than five dozen books on natural history, including Sandhill and Whooping Cranes: Ancient Voices over America's Wetlands and Seasons of the Tallgrass Prairie: A Nebraska Year.

An indispensable and highly readable introduction to the ecosystem of the shortgrass prairie, Prairie Dog Empire describes in clear and detailed terms the habitat and habits of black-tailed prairie dogs; their subsistence, seasonal behaviour, and the makeup of their vast colonies; and the ways in which their "towns" transform the surrounding terrain--for better or worse. Johnsgard recounts how this terrain was in turn transformed over the past century by the destruction of prairie dogs and their grassland habitats, together with the removal of the bison and their replacement with domestic livestock. A disturbing look at profound ecological alterations in the environment, this book also offers a rare and invaluable close-up view of the rich history and threatened future of the creature once considered the "keystone" species of the western plains.
