Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth overview on the functional ecology of daily torpor and hibernation in endothermic mammals and birds. The reader is well introduced to the physiology and thermal energetics of endothermy and underlying different types of torpor. Furthermore, evolution of endothermy as well as reproduction and survival strategies of heterothermic animals in a changing environment are discussed. Endothermic mammals and birds can use internal heat production fueled by ingested food to maintain a high body temperature. As food in the wild is not always available, many birds and mammals periodically abandon energetically costly homeothermic thermoregulation and enter an energy-conserving state of torpor, which is the topic of this book. Daily torpor and hibernation (multiday torpor) in these heterothermic endotherms are the most effective means for energy conservation available to endotherms and are characterized by pronounced temporal and controlled reductions in body temperature, energy expenditure, water loss, and other physiological functions. Hibernators express multiday torpor predominately throughout winter, which substantially enhances winter survival. In contrast, daily heterotherms use daily torpor lasting for several hours usually during the rest phase, some throughout the year. Although torpor is still widely considered to be a specific adaptation of a few cold-climate species, it is used by many animals from all climate zones, including the tropics, and is highly diverse with about 25-50% of all mammals, but fewer birds, estimated to use it. While energy conservation during adverse conditions is an important function of torpor, it is also employed to permit or facilitate energy-demanding processes such as reproduction and growth, especially when food supply is limited. Even migrating birds enter torpor to conserve energy for the next stage of migration, whereas bats may use it to deal with heat. Even though many heterothermic species will be challenged by anthropogenic influences such as habitat destruction, introduced species, novel pathogens and specifically global warming, not all are likely to be affected in the same way. In fact it appears that opportunistic heterotherms because of their highly flexible energy requirements, ability to limit foraging and reduce the risk of predation, and often pronounced longevity, may be better equipped to deal with anthropogenic challenges than homeotherms. In contrast strongly seasonal hibernators, especially those restricted to mountain tops, and those that have to deal with new diseases that are difficult to combat at low body temperatures, are likely to be adversely affected. This book addresses researchers and advanced students in Zoology, Ecology and Veterinary Sciences.

Book excerpt: Winner of the Don D. and Catherine S. Fowler Prize We are nearly all intrigued by the petroglyphs and pictographs of the American Southwest, and we commonly ask what they "mean." Religion on the Rocks redirects our attention to the equally important matter of what compelled ancient peoples to craft rock art in the first place. To examine this question, Aaron Wright presents a case study from Arizona's South Mountains, an area once flanked by several densely populated Hohokam villages. Synthesizing results from recent archaeological surveys, he explores how the mountains' petroglyphs were woven into the broader cultural landscape and argues that the petroglyphs are relics of a bygone ritual system in which people vied for prestige and power by controlling religious knowledge. The features and strategic placement of the rock art suggest this dimension of Hohokam ritual was participatory and prominent in village life. Around AD 1100, however, petroglyph creation and other ritual practices began to wane, denoting a broad transformation of the Hohokam social world. Wright's examination of the South Mountains petroglyphs offers a novel narrative of how Hohokam villagers negotiated a concentration of politico-religious authority around platform mounds. Readers will come away with a better understanding of the Hohokam legacy and a greater appreciation for rock art's value to anthropology.

Download or read book The Archaeology of Rock Art written by Christopher Chippindale and published by Cambridge University Press. This book was released on 1998 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pictures, painted and carved in caves and on open rock surfaces, are amongst our loveliest relics from prehistory. This pioneering set of sparkling essays goes beyond guesses as to what the pictures mean, instead exploring how we can reliably learn from rock-art as a material record of distant times: in short, rock-art as archaeology. Sometimes contact-period records offer some direct insight about indigenous meaning, so we can learn in that informed way. More often, we have no direct record, and instead have to use formal methods to learn from the evidence of the pictures themselves. The book's eighteen papers range wide in space and time, from the Palaeolithic of Europe to nineteenth-century Australia. Using varied approaches within the consistent framework of informed and proven methods, they make key advances in using the striking and reticent evidence of rock-art to archaeological benefit.

Download or read book The Archaeology of Ritual written by Evangelos Kyriakidis and published by Cotsen Institute of Archaeology Press. This book was released on 2007-12-31 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide spectrum of scholars, historians, art historians, anthropologists, students of performance, students of religion, archaeologists, cognitive scientists, and linguists were all asked to think and comment on how ritual can be traced in archaeology and which ways ritual research can go in that discipline. The product is a fairly accurate representation of research on ritual and the archaeology of ritual: scholars from various disciplines, backgrounds and agendas, arguing mostly in the most logical fashion, yet with little agreement between them. So this book should not be seen as presenting one unified attitude towards ritual and its study in archaeology. It should rather be seen as a reflection of what the discourse in the archaeology of ritual is today. The outcome has been extremely thought-provoking, often controversial, but always of extremely high quality.

Available in PDF, EPUB and Kindle. Book excerpt: From two veteran ecologists comes a new and sweeping exploration of the natural history of Texas in all its biological diversity and geological variation. Few states, if any, can match Texas for its myriad species, past and present, and its many distinctive landscapes, from prairie grasslands and hardwood forests to coastal lagoons and desert mountains. Beginning with the stories of how biologists and naturalists have over time defined the ecological areas of this very big state, the authors visit each of the eleven regions, including the Texas coast. They describe the dominant flora and fauna of each, explain the defining geologic features, and highlight each region's unique characteristics, such as carnivorous plants in the Piney Woods and returning black bears in the Trans-Pecos. Throughout, the authors remain especially conscious of the conservation and management issues affecting the natural resources of each region, revealing their deep affection for and knowledge about the state. Bolstered by a glossary, further reading suggestions, a description of state symbols, and an appendix of scientific names, this is an educational and essential volume for all Texans.

Download or read book Dodging Elephants written by J. Fred Bucy and published by . This book was released on 2014 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dodging Elephants tells the story of how a contented teenage soda jerk from Tahoka, Texas, with no plan for his future, found his way to higher education, landed a research job at Texas Instruments, and, over three decades, helped move that company from a small, oil-searching firm to a worldwide electronics giant. From the start J. Fred Bucy was a tireless, driven manager who turned failures into successes. Taking on TI's government equipment division in 1963, he successfully championed ingenious new designs. In 1967 he moved to the company's volatile, ever-expanding semiconductor division, establishing factories worldwide. Meanwhile, he had become an influential advisor on U.S. government export regulation. By 1976, when TI was competing in the consumer market, he was the company's president. Bucy left TI in 1985 after a brief term as CEO. His autobiography is rich in anecdotes and unsparingly honest. Growing up on the rural South Plains of Texas in the years of the Great Depression, Dust Bowl, and World War II, Fred Bucy learned the value of self-reliance and hard work. He seemed headed for a farming career when his life took an abrupt turn. Against substantial odds, and with a family to support, he earned two degrees in Physics and, in 1953, joined a young but promising company, Texas Instruments Incorporated. For the next thirty years he played a major role in TI's phenomenal growth and history-making innovation, moving steadily upward, becoming TI's president in 1976 and its CEO in 1984. It was a tough climb. Along the way he successfully managed a variety of brilliant, often endangered projects including digital computers, sophisticated weaponry, and complex semiconductors, playing a crucial role in the explosive, worldwide expansion of microchip technology.
