Download or read book The Paleoanthropology and Archaeology of Big Game Hunting written by John D. Speth and published by Springer Science & Business Media. This book was released on 2010-09-08 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its inception, paleoanthropology has been closely wedded to the idea that big-game hunting by our hominin ancestors arose, first and foremost, as a means for acquiring energy and vital nutrients. This assumption has rarely been questioned, and seems intuitively obvious—meat is a nutrient-rich food with the ideal array of amino acids, and big animals provide meat in large, convenient packages. Through new research, the author of this volume provides a strong argument that the primary goals of big-game hunting were actually social and political—increasing hunter’s prestige and standing—and that the nutritional component was just an added bonus. Through a comprehensive, interdisciplinary research approach, the author examines the historical and current perceptions of protein as an important nutrient source, the biological impact of a high-protein diet and the evidence of this in the archaeological record, and provides a compelling reexamination of this long-held conclusion. This volume will be of interest to researchers in Archaeology, Evolutionary Biology, and Paleoanthropology, particularly those studying diet and nutrition.

Download or read book Aquatic Biodiversity II written by H. Segers and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.

Download or read book Neuropeptide Systems as Targets for Parasite and Pest Control written by Timothy G. Geary and published by Springer Science & Business Media. This book was released on 2011-01-13 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.

Download or read book Chemicals via Higher Plant Bioengineering written by Fereidoon Shahidi and published by Springer Science & Business Media. This book was released on 1999-05-31 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en forced in food production. At the same time, there is an increasing demand for high qual ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the area of plant biotechnology and bioengineering has allowed manipulation of genes' !lnd/or insertion of new genes, thus production of trans genic plants. Starting from the introduction of agronomic traits, particularly stress resis tance to diverse environmental factors, process and sensory characteristics, food quality and production of novel varieties of plant-based products through genetic engineering, biotechnology is changing the,;agriculture and the concept of production of plant-ba~~d raw materials. Increasing attention is being paid on research for production of plants !pat can provide a wide array of food and non-food products. Perhaps the first non-food pro,d uct that plant biotechnology would achieve is production of large scale custom-designed industrial oils, but the list of chemicals is long, ranging" from oils and specific triacyl glycerols to biopolymers, enzymes, blood components, amo~g others.

Download or read book Biotechnology in Surgery written by Alfonso Barbarisi and published by Springer Science & Business Media. This book was released on 2010-12-28 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 20th century has finished, the century when surgery took huge steps forward thanks to progress in technology. Now we have entered the "century of biotechnologies", which will not only generate progress in surgery, but also lead to a real "cultural revolution" that will completely change approaches to solving different problems in medicine. The aim of this book is to bring surgeons closer to biotechnologies and to overcome the cultural gap dividing them from these new approaches. Biotechnologies are already proposed and used at different levels in surgical practice: in diagnostic technique, enabling practitioners to identify diseases at an early stage and follow their molecular modification over time; and in tissue engineering, where the use of "smart scaffolds" offers a possible answer to increasing demand for biocompatible tissues and organs in transplantation surgery. This volume focuses on the emerging field of stem cells, analyzing both their role as possible players in originating and perpetuating cancer – "cancer stem cells" – and, conversely, their extraordinary therapeutical potential. An additional section is dedicated to the evaluation and application of derived molecular factors that can enhance the physiological processes that are fundamentally important in surgery, such as hemostasis and wound healing. Surgeons have always been technologists, in the sense that since surgery began they have always needed technology, beginning with a scalpel and surgical instruments. They have always cooperated with technologists. However, in the new century, the first one of the millennium, a rapid increase in knowledge that is outside the realm of the surgeon’s traditional technological training is imposing itself – hence the aim of this book. It is now urgent to encourage surgeons to embrace this knowledge (biotechnology) with confidence. By its very nature, biotechnology is completely different from the technologies used so far, because it escapes the senses of sight and touch, which up to now have been the essence of the surgeon’s work. The cellular and molecular dimensions of biotechnologies are still far removed from most of the recent advances in modern surgical techniques. A common language between surgeons and biotechnologists will create further, revolutionary, progress in surgical sciences in the twenty-first century.

Available in PDF, EPUB and Kindle. Book excerpt: The general interest and attention paid to the use of the renewable natural resources of the world have increased greatly during the last decades. This is due to the environmental dilemma into which mankind has got itself by the total disregard of ecological facts and laws, the underprizing of natural resources and the overemphasis on economic develop ment, coupled with unimpeded rapid population growth and the preponderance of material istic consumption-oriented attitudes. The management and use of natural resources such as forests, grasslands, rivers and lakes were formerly considered purely in a financial context, whereas latterly, a consciousness of their social function and the indirect economic benefits which can be derived from them has developed. Thus, as regards these traditional resources, multi-use concepts comprising eco nomically oriented utilisation as well as recreational, educational and social use have be come widely accepted. Conservation of natural resources for sustainable consumptive as well as non-consumptive uses has been recognised as a key element for maintaining eco nomic development all over the world. Fortunately, the industrialised countries have started to apply this principle themselves and in their technical and financial aid to the developing Third World countries. This is manifest from policy documents such as the World Bank Policy on Development of Wild Lands, issued in 1987.

Download or read book How to Kill a Dragon written by Calvert Watkins and published by Oxford University Press, USA. This book was released on 1995 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: In How to Kill a Dragon Calvert Watkins follows the continuum of poetic formulae in Indo-European languages, from Old Hittite to medieval Irish. He uses the comparative method to reconstruct traditional poetic formulae of considerable complexity that stretch as far back as the original common language. Thus, Watkins reveals the antiquity and tenacity of the Indo-European poetic tradition. Watkins begins this study with an introduction to the field of comparative Indo-European poetics; he explores the Saussurian notions of synchrony and diachrony, and locates the various Indo-European traditions and ideologies of the spoken word. Further, his overview presents case studies on the forms of verbal art, with selected texts drawn from Indic, Iranian, Greek, Latin, Hittite, Armenian, Celtic, and Germanic languages. In the remainder of the book, Watkins examines in detail the structure of the dragon/serpent-slaying myths, which recur in various guises throughout the Indo-European poetic tradition. He finds the "signature" formula for the myth--the divine hero who slays the serpent or overcomes adversaries--occurs in the same linguistic form in a wide range of sources and over millennia, including Old and Middle Iranian holy books, Greek epic, Celtic and Germanic sagas, down to Armenian oral folk epic of the last century. Watkins argues that this formula is the vehicle for the central theme of a proto-text, and a central part of the symbolic culture of speakers of the Proto-Indo-European language: the relation of humans to their universe, the values and expectations of their society. Therefore, he further argues, poetry was a social necessity for Indo- European society, where the poet could confer on patrons what they and their culture valued above all else: "imperishable fame."

Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Download or read book Beyond Memory written by Diane Neumaier and published by Rutgers University Press. This book was released on 2004 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photography possesses a powerful ability to bear witness, aid remembrance, shape, and even alter recollection. In Beyond Memory: Soviet Nonconformist Photography and Photo-Related Works of Art, the general editor, Diane Neumaier, and twenty-three contributors offer a rigorous examination of the medium's role in late Soviet unofficial art. Focusing on the period between the mid-1950s and the late 1980s, they explore artists' unusually inventive and resourceful uses of photography within a highly developed Soviet dissident culture. During this time, lack of high-quality photographic materials, complimented by tremendous creative impulses, prompted artists to explore experimental photo-processes such as camera and darkroom manipulations, photomontage, and hand-coloring. Photography also took on a provocative array of forms including photo installation, artist-made samizdat (self-published) books, photo-realist painting, and many other surprising applications of the flexible medium. Beyond Memory shows how innovative conceptual moves and approaches to form and content-echoes of Soviet society's coded communication and a Russian sense of absurdity-were common in the Soviet cultural underground. Collectively, the works in this anthology demonstrate how late-Soviet artists employed irony and invention to make positive use of difficult circumstances. In the process, the volume illuminates the multiple characters of photography itself and highlights the leading role that the medium has come to play in the international art world today. Beyond Memory stands on its own as a rigorous examination of photography's place in late Soviet unofficial art, while also serving as a supplement to the traveling exhibition of the same title.

This book was released on 2011-09-26 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of biology is populated by numerous model species or organisms. But few vertebrate groups have aided evolutionary and ecological research more than the live-bearing fishes of the family Poeciliidae. Found throughout tropical and subtropical waters, poeciliids exhibit a fascinating variety of reproductive specializations, including viviparity, matrotrophy, unisexual reproduction, and alternative mating strategies, making them ideal models for research on patterns and processes in ecology, behavior, and evolution. Ecology and Evolution of Poeciliid Fishes is a much-needed overview of the scientific potential and understanding of these live-bearing fishes. Chapters by leading researchers take up a wide range of topics, including the evolution of unisexual reproduction, life in extreme environments, life-history evolution, and genetics. Designed to provide a single and highly approachable reference, Ecology and Evolution of Poeciliid Fishes will appeal to students and specialists interested in all aspects of evolutionary ecology.
