Description: Science is interesting to Brown if "it changes my view of the natural world and challenges rather than confirms existing dogma." He does both in advocating a nonexperimental approach, based upon emergent statistical properties of individuals/species, to studying ecological and evolutionary processes that determine species diversity, abundance, and distribution. By linking population dynamics and species interactions (small-scale processes) with speciation, extinction, and range expansion/contraction (large-scale processes), Brown argues that "macroecology" has greater potential for generality than its reductionist, experimental counterpart. After developing macroecology's conceptual rationale, the book reflects a logical progression of data (primarily on mammals and birds, e.g., associations between local abundance and geographic distribution; patterns in body size, density, and energetics), mechanisms, hypothesis formulation, and a synthesis exploring the implications of macroecology to ecological, biogeographical, evolutionary, and conservation issues. Stimulating (should fitness be defined in purely energetic terms?) and provocative (ecosystem energy flow is not dominated by small organisms), and very well written, Brown's book is intellectually enriching. His somewhat nontraditional approach merits serious consideration. Verbal rather than mathematical models; comprehensive figure captions. Upper-division undergraduate through faculty.--Choice Review.

In "Macroecology," James H. Brown proposes a radical new research agenda designed to broaden the scope of ecology to encompass vast geographical areas and very long time spans. While much ecological research is narrowly focused and experimental, providing detailed information that cannot be used to generalize from one ecological community or time period to another, macroecology draws on data from many disciplines to create a less detailed but much broader picture with greater potential for generalization. Integrating data from ecology, systematics, evolutionary biology, paleobiology, and biogeography to investigate problems that could only be addressed on a much smaller scale by traditional approaches, macroecology provides a richer, more complete understanding of how patterns of life have moved across the earth over time. Brown also demonstrates the advantages of macroecology for conservation, showing how it allows scientists to look beyond endangered species and ecological communities to consider the long history and large geographic scale of human impacts. An important reassessment of the direction of ecology by one of the most influential thinkers in the field, this work will shape future research in ecology and other disciplines. "This approach may well mark a major new turn in the road in the history of ecology, and I find it extremely exciting. The scope of Macroecology is tremendous and the book makes use of its author's exceptionally broad experience and knowledge. An excellent and important book."
