Large Carnivores and the Conservation of Biodiversity brings together more than thirty leading scientists and conservation practitioners to consider a key question in environmental conservation: Is the conservation of large carnivores in ecosystems that evolved with their presence equivalent to the conservation of biological diversity within those systems? Building their discussions from empirical, long-term data sets, contributors including James A. Estes, David S. Maehr, Tim McClanahan, Andrès J. Novaro, John Terborgh, and Rosie Woodroffe explore a variety of issues surrounding the link between predation and biodiversity: What is the evidence for or against the link? Is it stronger in marine systems? What are the implications for conservation strategies? Large Carnivores and the Conservation of Biodiversity is the first detailed, broad-scale examination of the empirical evidence regarding the role of large carnivores in biodiversity conservation in both marine and terrestrial ecosystems. It contributes to a much more precise and global understanding of when, where, and whether protecting and restoring top predators will directly contribute to the conservation of biodiversity. Everyone concerned with ecology, biodiversity, or large carnivores will find this volume a unique and thought-provoking analysis and synthesis.

In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.

Elephants are among the most magnificent – but also most problematic –members of South Africa's wildlife population. While they are sought after by South African and foreign tourists alike, they also have a major impact on their environment. As a result, elephant management has become a highly complex and often controversial discipline. The information needed to underpin vital decisions about elephant management has largely been unavailable to decision-makers, contested by experts, or simply unknown. As a result, the South African Minister for Environmental Affairs and Tourism convened a round table to advise him on this issue. The round table recommended that a scientific assessment of elephant management be undertaken to gather, evaluate, and present all the relevant information on this topic. Its main findings and recommendations are contained in this volume. Elephant Management is the first book of its kind, combining the work of more than 60 national and international experts. Extensively reviewed by policy-makers and other stakeholders, it is the most systematic and comprehensive review of savanna elephant populations and factors relevant to managing them to date. As such it is of interest to a broad spectrum of readers in South Africa and elsewhere. Above all, it is aimed at helping conservation policy-makers and practitioners to choose the best possible options for the sustainable preservation of these iconic animals.

Birds and mammals can give us clues about our own behavior, and studying them can answer interesting questions, such as why is the World green, and why are plants the biggest organisms on land, but animals the largest in the oceans? Nevertheless the most compelling reason to study them is because it is fun, which is possibly the main message in this book.

Vine Deloria, Jr., leading Native American scholar and author of the best-selling God is Red, addresses the conflict between mainstream scientific theory about our world and the ancestral worldview of Native Americans. Claiming that science has created a largely fictional scenario for American Indians in prehistoric North America, Deloria offers an alternative view of the continent's history as seen through the eyes and memories of Native Americans. Further, he warns future generations of scientists not to repeat the ethnocentric omissions and fallacies of the past by dismissing Native oral tradition as mere legends.

Biotic Crises in Ecological and Evolutionary Time emerged from the third Field Museum Spring Systematic Symposium held in May 1980. The symposium attempted to explore the nature and effects of crisis over as wide a range of temporal and spatial scales as possible. To this end, contributions were included from such diverse fields as astronomy, paleobiology, ecology, and anthropology. The kinds of crises considered ranged from events in the cosmological history of the universe all the way to the effects of a single introduced species on a present-day living community. The book begins by providing a definition of ""crisis"" and a general discussion of methods and approaches to the study of crises. The subsequent chapters present studies on topics such as the physical mechanisms underlying the cosmological framework in which life evolved; physical disturbance in the life of plants; the impact of species introductions; and evolutionary aspects of pre- and post-interchange fossil land mammal faunas in South America.

Forgotten Grasslands of the South is the study of one of the biologically richest and most endangered ecosystems in North America. In a seamless blend of science and personal observation, renowned ecologist Reed Noss explains the natural history of southern grasslands, their origin and history, and the physical determinants of grassland distribution, including ecology, soils, landform, and hydrology. In addition to offering fascinating new information about these little-studied ecosystems, Noss demonstrates how natural history is central to the practice of conservation. Although theory and experimentation have recently dominated the field of ecology, ecologists are coming to realize how these distinct approaches are not divergent but complementary, and that pursuing them together can bring greater knowledge and understanding of how the natural world works and how we can best conserve it. This long-awaited work sets a new standard for scientific literature and is essential reading for those who study and work to conserve the grasslands of the South as well as for everyone who is fascinated by the natural world.

In 1977, the Volkswagen Foundation sponsored the first of a series of International Symposia on Fire Ecology at Freiburg University, Federal Republic of Germany. The scope of the congresses was to create a platform for researchers at a time when the science of fire ecology was not yet recognized and established outside of North America and Australia. Whereas comprehensive information on the fire ecology of the northern boreal, the temperate, and the mediter ranean biotas is meanwhile available, it was recognized that conside rable gaps in information exist on the role of fire in tropical und sub tropical ecosystems. Thus it seemed timely to meet the growing scientific interest and public demand for reliable and updated infor mation and to synthesize the available knowledge of tropical fire ecology and the impact of tropical biomass burning on global eco system processes. The Third Symposium on Fire Ecology, again sponsored by the Volkswagen Foundation and held at Freiburg University in May 1989, was convened to prepare this first pantropical and multidisci plinary monograph on fire ecology!. The book, in which 46 scientists cooperated, analyzes those fire-related ecosystem processes which have not yet been described in a synoptic way. Following the editor's concept, duplication at previous efforts in describing tropical vegeta tion patterns and dynamics was avoided. Extensive bibliographical sources are given in the reference lists of the chapters.

Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.
