One of the first textbooks in this emerging important field of ecology.Most of ecology is about metabolism: the ways that organisms use energy and materials. The energy requirements of individuals - their metabolic rates - vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. So metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology.

The book is intended to be accessible to upper-level undergraduate, and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. Together they make for an authoritative treatment that will inspire future generations to study metabolic ecology.

In this work, James H. Brown proposes a new research agenda designed to broaden the scope of ecology to encompass vast geographical areas and very long time spans. He demonstrates the advantages of macroecology for conservation, showing how it allows scientists to look beyond endangered species and ecological communities in order to consider the long history and large geographic scale of human impacts.

Scaling relationships are a persistent theme in biology. Examples include branching patterns of blood vessels, structural and functional correlates of body size, distribution of body size and abundance among species, and variations in populations within an area or over time. This book, based on a conference at the Santa Fe Institute, brings together many of the most prominent workers in the area to assess our current understanding of scaling relationships at the physiological, biomechanical, and ecological levels.

Physiological ecology has grown in importance as an area of biology in the past thirty years and integrates the diverse approaches used in the comparative biology of organisms. Biologists segregate their approaches by technique and concept, but the boundaries among ecology, behavior, anatomy, and physiology are arbitrary and of no significance to organisms. Physiological ecology emphasizes the diversity of not only organisms, but also of solutions to (and evasions of) problems posed by the environment.In a comprehensive and authoritative synthesis of physiological ecology supported by more than 3,100 references, Brian K. McNab demonstrates the intellectual cohesion of the field. To ground his discussion in clearly understood contexts, McNab emphasizes the common thread of energy expenditure throughout the text and limits the discussion to vertebrates, which have familiar habitats and comparatively well-known evolutionary histories.A thorough scientific resource and reference tool, Physiological Ecology of Vertebrates is the first book to cover this complex subject. It will be the standard reference and basis for much future research in this fast-growing field of study.
