Mammals range in body size from the gigantic blue whale to the tiny Etruscan shrew. Elephants and man may live for nearly one hundred years, while most shrews die before they are three months old. During the past decade, mammalogists and evolutionary biologists have begun to unravel the numerous factors that shape the enormous diversity of mammal life histories. In this volume, leading scientists provide a variety of perspectives on the newest theories in this active field of study. The principle uniting all studies of life history evolution is adaptation by natural selection. The first...

In 1872 Congress designated Yellowstone National Park as the world's first national park; nineteen years later, the land adjacent to Yellowstone became America's first national forest reserve. Since that time, the entire Yellowstone region has been the scene of major battles over resource management--debates between those who would use the land for extraction of national resources (mining, lumbering, and hunting, for example) and those who believe that wildlife and recreation should dominate land use.
In this book, experts in science, economics, and law discuss key resource...

Until recently, natural resource management of such commodities as timber and wildlife was driven largely by the desire to exploit these resources. During the past three decades, however, ecologists have warned that this approach to natural resource management could have unforeseen consequences because it ignored how ecosystems function within the landscape. Federal agencies that oversee forest and wildlife resources have begun to implement different schemes of ecosystem management, schemes that vary enormously among agencies. Contributors to this volume--leading experts who are agency...

The management of the elk population at Jackson Hole, Wyoming, has been the subject of a long-standing controversy among wildlife biologists, with critics of the winter feeding program predicting that such intervention would result in overpopulation, habitat destruction, disease and chaos. After more than 75 years in which hay has been provided during the winter months in most years, the elk population is flourishing and is for good measure one of the most intensively studied and managed wildlife populations in North America. This detailed study of migration, population dynamics, harvesting...
