Pronghorn antelope are the fastest runners in North America, clocked at speeds of up to 100 kilometers per hour. Yet none of their current predators can come close to running this fast. Pronghorn also gather in groups, a behavior commonly viewed as a "safety in numbers" defense. But again, none of their living predators are fearsome enough to merit such a response.

In this elegantly written book, John A. Byers argues that these mystifying behaviors evolved in response to the dangerous predators with whom pronghorn shared their grassland home for nearly four million years: among them fleet hyenas, lions, and cheetahs. Although these predators died out ten thousand years ago, pronghorn still behave as if they were present—as if they were living with the ghosts of predators past.

Byers's provocative hypothesis will stimulate behavioral ecologists and mammalogists to consider whether other species' adaptations are also haunted by selective pressures from predators past. The book will also find a ready audience among evolutionary biologists and paleontologists.

A Wildlife Management Institute Book

In this lavishly illustrated volume Richard E. McCabe, Bart W. O'Gara and Henry M. Reeves explore the fascinating relationship of pronghorn with people in early America, from prehistoric evidence through the Battle of Little Bighorn in 1876. The only one of fourteen pronghorn-like genera to survive the great extinction brought on by human migration into North America, the pronghorn has a long and unique history of interaction with humans on the continent, a history that until now has largely remained unwritten.

 With nearly 150 black-and-white photographs, 16 pages of color illustrations, plus original artwork by Daniel P. Metz, Prairie Ghost: Pronghorn and Human Interaction in Early America tells the intriguing story of humans and these elusive big game mammals in an informative and entertaining fashion that will appeal to historians, biologists, sportsmen and the general reader alike.
