Serves as the focal concept in a search for a truly functional document access system, enabling us to stand back from the present, to look into the shadows of our current designs, marvel at the breadth of human search capabilities, recognize frailties in both humans and systems, and ask new questions as we grapple with navigating our information environment. O'Connor and Copeland offer three different arenas of nontrivial information seeking for our consideration: "Submarine Chasing" explores the thoughts of a highly decorated Cold War submarine hunter. "Bounty Hunting" involves a long and convoluted search for a reported bond skipper. "Engineering Design" presents a content analysis of the few works on epistemological foundations of engineering design activity. These stories, told at great length and in considerable detail, are framed within a foundational model that links the simple act of document seeking to the broader issue of making one's way through life in the physical world. In each case, the authors ramble, mull, and stumble upon ideas without the least prior constraint, developing some threads quite fully and leaving others to tease us, but never ever throwing us to the lions.

An interdisciplinary text on the world's savannas, covering the geography, ecology, economics and politics of savanna regions. Savannas are a distinct vegetation type, covering a third of the world's land surface area and supporting a fifth of the world's population. There has been a wide range of literature on the subject, but the majority of work has focused on the ecology or development of savanna areas, ignoring the wider interdisciplinary issues affecting contemporary savannas. World Savannas aims to buck this trend, providing students with an up-to-date and comprehensive introduction to the global importance of savannas.

This book compiles a collection of case studies analysing drivers of and responses to change amongst contemporary hunter-gatherers. Contemporary hunter-gatherers’ livelihoods are examined from perspectives ranging from historical legacy to environmental change, and from changes in national economic, political and legal systems to more broad-scale and universal notions of globalization and acculturation. Far from the commonly held romantic view that hunter-gatherers continue to exist as isolated populations living a traditional lifestyle in harmony with the environment, contemporary hunter-gatherers – like many rural communities around the world - face a number of relatively new ecological and social challenges to which they are pressed to adapt. Contemporary hunter-gatherer societies are increasingly and rapidly being affected by Global Changes, related both to biophysical Earth systems (i.e., changes in climate, biodiversity and natural resources, and water availability), and to social systems (i.e. demographic transitions, sedentarisation, integration into the market economy, and all the socio-cultural change that these and other factors trigger). Chapter 10 of this book is open access under a CC BY 4.0 license.

Hunting and gathering is humanity's first and most successful adaptation. Until 12,000 years ago, all humanity lived this way. Surprisingly, in an increasingly urbanized and technological world dozens of hunting and gathering societies have persisted and thrive worldwide, resilient in the face of change, their ancient ways now combined with the trappings of modernity. The Encyclopedia is divided into three parts. The first contains case studies, by leading experts, of over fifty hunting and gathering peoples, in seven major world regions. There is a general introduction and an archaeological overview for each region. Part II contains thematic essays on prehistory, social life, gender, music and art, health, religion, and indigenous knowledge. The final part surveys the complex histories of hunter-gatherers' encounters with colonialism and the state, and their ongoing struggles for dignity and human rights as part of the worldwide movement of indigenous peoples.

The Hadza, an ethnic group indigenous to northern Tanzania, are one of the few remaining hunter-gatherer populations. Archaeology shows 130,000 years of hunting and gathering in their land but Hadza are rapidly losing areas vital to their way of life. This book offers a unique opportunity to capture a disappearing lifestyle. Blurton Jones interweaves data from ecology, demography and evolutionary ecology to present a comprehensive analysis of the Hadza foragers. Discussion centres on expansion of the adaptationist perspective beyond topics customarily studied in human behavioural ecology, to interpret a wider range of anthropological concepts. Analysing behavioural aspects, with a specific focus on relationships and their wider impact on the population, this book reports the demographic consequences of different patterns of marriage and the availability of helpers such as husbands, children, and grandmothers. Essential for researchers and graduate students alike, this book will challenge preconceptions of human sociobiology.

The forest foragers of the Congo Basin, known collectively as "Pygmies," are the largest and most diverse group of active hunter-gatherers remaining in the world. At least fifteen different ethno-linguistic groups exist in the Congo Basin with a total population of 250,000 to 350,000 individuals. Extensive knowledge about these groups has accumulated in the last forty years, but readers have been forced to piece together what is known from many sources. French, Japanese, American, and British researchers have conducted the majority of the research; each national research group has its own academic traditions, history, and publications. Here, leading academic authorities from diverse national traditions summarize recent research on forest hunter-gatherers. The volume explores the diversity and uniformity of Congo Basin hunter-gatherer life by providing detailed but accessible overviews of recent research. It represents the first book in over twenty-five years to provide a comprehensive and holistic overview of African forest hunter-gatherers. Chapters discuss the cultural variation in characteristic features of Congo Basin hunter-gatherer life, such as their yodeled polyphonic music, pronounced egalitarianism, multiple-child caregiving, and complex relations with neighboring farming groups. Other contributors address theoretical issues, such as why Pygmies are short, how tropical forest hunter-gatherers live without the carbohydrates they receive from neighboring farmers, and how hunter-gatherer children learn to share so extensively.

An examination of nature's extraordinary biological diversity and the human activities that threaten it. Life on Earth: An Encyclopedia of Biodiversity, Ecology, and Evolution tackles the critical issue for humanity in the 21st century—our ever more menacing impact on the environment. This two-volume, illustrated set, edited by American Museum of Natural History curator Niles Eldredge, begins with biodiversity, the complex planetary web of life that has emerged through three billion years of evolution. How does it work? And why is its continued health critical to the planet and to ourselves? More than 50 top scholars examine every form of life from amoebae to elephants, from plankton to whales. But Life on Earth is more than a catalog of species. An A–Z survey explores the myriad ways humanity is diminishing that biodiversity, from industrialization to natural habitat destruction, from overpopulation in the developing world to an unsustainable consumer lifestyle in the West. Life on Earth is the essential reference work for anyone curious about our planet's extraordinary diversity of life and the unprecedented threats it faces.

A comprehensive introduction to tropical ecology This full-color illustrated textbook offers the first comprehensive introduction to all major aspects of tropical ecology. It explains why the world's tropical rain forests are so universally rich in species, what factors may contribute to high species richness, how nutrient cycles affect rain forest ecology, and how ecologists investigate the complex interrelationships among flora and fauna. It covers tropical montane ecology, riverine ecosystems, savanna, dry forest—and more. Tropical Ecology begins with a historical overview followed by a sweeping discussion of biogeography and evolution, and then introduces students to the unique and complex structure of tropical rain forests. Other topics include the processes that influence everything from species richness to rates of photosynthesis: how global climate change may affect rain forest characteristics and function; how fragmentation of ecosystems affects species richness and ecological processes; human ecology in the tropics; biodiversity; and conservation of tropical ecosystems and species. Drawing on real-world examples taken from actual research, Tropical Ecology is the best textbook on the subject for advanced undergraduates and graduate students. Offers the first comprehensive introduction to tropical ecology Describes all the major kinds of tropical terrestrial ecosystems Explains species diversity, evolutionary processes, and coevolutionary interactions Features numerous color illustrations and examples from actual research Covers global warming, deforestation, reforestation, fragmentation, and conservation The essential textbook for advanced undergraduates and graduate students Suitable for courses with a field component Leading universities that have adopted this book include: Biola University Bucknell University California State University, Fullerton Colorado State University - Fort Collins Francis Marion University Michigan State University Middlebury College Northern Kentucky University Ohio Wesleyan University St. Mary's College of Maryland Syracuse University Tulane University University of California, Santa Cruz University of Central Florida University of Cincinnati University of Florida University of Missouri University of New Mexico University of North Carolina at Chapel Hill University of the West Indies

In this book, Jonathan H. Turner combines sociology, evolutionary biology, cladistic analysis from biology, and comparative neuroanatomy to examine human nature as inherited from common ancestors shared by humans and present-day great apes. Selection pressures altered this inherited legacy for the ancestors of humans—termed hominins for being bipedal—and forced greater organization than extant great apes when the hominins moved into open-country terrestrial habitats. The effects of these selection pressures increased hominin ancestors’ emotional capacities through greater social and group orientation. This shift, in turn, enabled further selection for a larger brain, articulated speech, and culture along the human line. Turner elaborates human nature as a series of overlapping complexes that are the outcome of the inherited legacy of great apes being fed through the transforming effects of a larger brain, speech, and culture. These complexes, he shows, can be understood as the cognitive complex, the psychological complex, the emotions complex, the interaction complex, and the community complex.
