Since the early 1940s, North America has been the focus of studies of free-ranging wolves. Much of Canada and most of Alaska support numerous, viable and sometimes thriving wolf populations. This comprehensive text considers the behavior and ecology of wild wolves in North America, Europe, Eurasia, Israel, and Iran. It also discusses wolf behavior in captivity and methods of conservation. This book and others in the Animal Science series have been used as textbooks in classrooms across the world.
