Desert Frontier is a study of the ecological and economic impact of a long-term trend toward increasing aridity along the southern edge of the western Sahara. Beginning in the early seventeenth century, this climatological trend forced the desert approximately 200–300 kilometers to the south, transforming ethnic identities and ways of life along the length of the Sahel. Based on extensive archival research and on Saharan oral data, Desert Frontier argues that the principal historical dynamics of the precolonial Sahel were determined by this pervasive ecological crisis, rather than by the dynamics of a European-dominated world system.

Using an energy systems language that combines energetics, kinetics, information, cybernetics, and simulation, Ecological and General Systems compares models of many fields of science, helping to derive general systems principles.

First published as Systems Ecology in 1983, Ecological and General Systems proposes principles of self-organization and the designs that prevail by maximizing power and efficiency. Comparisons to fifty other systems languages are provided. Innovative presentations are given on earth homeostasis (Gaia); the inadequacy of presenting equations without network relationships and energy constraints; the alternative interpretation of high entropy complexity as adaptive structure; basic equations of ecological economics; and the energy basis of scientific hierarchy.

Part I introduces energetics, hierarchy, and systems modeling. Part II features design elements: intersections, autocatalytic modules, loops, series, parallel elements, and webs. Part III includes embodied energy, spectra of energy quality, temperature, complexity, spatial distribution, and diversity. Part IV discusses production, consumption, ecosystems, succession, economic systems, anthropological models, urban and regional models, global biogeochemistry, and the universe.

Over the past several decades, the field of invasion biology has rapidly expanded as global trade and the spread of human populations have increasingly carried animal and plant species across natural barriers that have kept them ecologically separated for millions of years. Because some of these nonnative species thrive in their new homes and harm environments, economies, and human health, the prevention and management of invasive species has become a major policy goal from local to international levels.

Yet even though ecological research has led to public conversation and policy recommendations, those recommendations have frequently been ignored, and the efforts to counter invasive species have been largely unsuccessful. Recognizing the need to engage experts across the life, social, and legal sciences as well as the humanities, the editors of this volume have drawn together a wide variety of ecologists, historians, economists, legal scholars, policy makers, and communications scholars, to facilitate a dialogue among these disciplines and understand fully the invasive species phenomenon. Aided by case studies of well-known invasives such as the cane toad of Australia and the emerald ash borer, Asian carp, and sea lampreys that threaten US ecosystems, Invasive Species in a Globalized World offers strategies for developing and implementing anti-invasive policies designed to stop their introduction and spread, and to limit their effects.

Scattered throughout the Great Plains are many isolated areas of varying size and ecology, quite distinct from the surrounding grasslands. Such spaces can be uplands like the Black Hills, low hills like the Nebraska Sand Hills, or linear areas such as shallow river valleys and deeply incised canyons. While the notion of “islands” is not a new one among ecologists, its application in Plains archaeology is.

The contributors to this volume seek to illustrate the different ways that the spatial, structural, and temporal nature of islands conditioned the behavior and adaptation of past Plains peoples. This as a first step toward a more detailed analysis of habitat variation and its effects on Plains cultural dynamics and evolution. Although the emphasis is on ecology, several chapters also address social and ideological islands in the form of sacred sites and special hunting grounds.

As we search urgently for a strategy of sustainable natural resource management, an international debate is brewing over destructive modern fishery methods. Namibia's Fisheries is a timely contribution to this discussion as it examines Namibia’s Benguela upwelling system, an area that supports traditional and modern forms of fishery. This volume analyzes the Namibian experience in fishery management, featuring essays by researchers, Namibian fishery managers, and international specialists that cover a range of ecological and social issues. Namibia's Fisheries will be a valuable resource for researchers, conservationists, and students of fishery management.

Rodent Societies synthesizes and integrates the current state of knowledge about the social behavior of rodents, providing ecological and evolutionary contexts for understanding their societies and highlighting emerging conservation and management strategies to preserve them. It begins with a summary of the evolution, phylogeny, and biogeography of social and nonsocial rodents, providing a historical basis for comparative analyses. Subsequent sections focus on group-living rodents and characterize their reproductive behaviors, life histories and population ecology, genetics, neuroendocrine mechanisms, behavioral development, cognitive processes, communication mechanisms, cooperative and uncooperative behaviors, antipredator strategies, comparative socioecology, diseases, and conservation. Using the highly diverse and well-studied Rodentia as model systems to integrate a variety of research approaches and evolutionary theory into a unifying framework, Rodent Societies will appeal to a wide range of disciplines, both as a compendium of current research and as a stimulus for future collaborative and interdisciplinary investigations.
