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...

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...

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...

This book is a collection of essays and an edited selection of the work produced by Design Studio 18 (DS18) tutored by Lindsay Bremner and Roberto Bottazzi in the Department of Architecture at the University of Westminster, 2013-2015. The aim of the studio over this period was to approach problems of energy, energy infrastructure and resource extraction as architectural questions i.e. as political, cultural and aesthetic problems, as much as technological ones. Computational tools were used to simulate material processes and to enlist, visualise and enliven data in the service of design.
