Frozen mammals of the Ice Age, preserved for millennia in the tundra, have been a source of fascination and mystery since their first discovery over two centuries ago. These mummies, their ecology, and their preservation are the subject of this compelling book by paleontologist Dale Guthrie. The 1979 find of a frozen, extinct steppe bison in an Alaskan gold mine allowed him to undertake the first scientific excavation of an Ice Age mummy in North America and to test theories about these enigmatic frozen fauna. The 36,000-year-old bison mummy, coated with blue mineral crystals, was dubbed "Blue Babe." Guthrie conveys the excitement of its excavation and shows how he made use of evidence from living animals, other Pleistocene mummies, Paleolithic art, and geological data. With photographs and scores of detailed drawings, he takes the reader through the excavation and subsequent detective work, analyzing the animal's carcass and its surroundings, the circumstances of its death, its appearance in life, the landscape it inhabited, and the processes of preservation by freezing. His examination shows that Blue Babe died in early winter, falling prey to lions that inhabited the Arctic during the Pleistocene era. Guthrie uses information gleaned from his study of Blue Babe to provide a broad picture of bison evolutionary history and ecology, including speculations on the interactions of bison and Ice Age peoples. His description of the Mammoth Steppe as a cold, dry, grassy plain is based on an entirely new way of reading the fossil record.

First published in 1963, Advances in Parasitology contains comprehensive and up-to-date reviews in all areas of interest in contemporary parasitology. Advances in Parasitology includes medical studies on parasites of major influence, such as Plasmodium falciparum and trypanosomes. The series also contains reviews of more traditional areas, such as zoology, taxonomy, and life history, which shape current thinking and applications. Eclectic volumes are supplemented by thematic volumes on various topics, including control of human parasitic diseases and global mapping of infectious diseases.

Twenty-five thousand years ago, sea level fell more than 400 feet below its present position as a consequence of the growth of immense ice sheets in the Northern Hemisphere. A dry plain stretching 1,000 miles from the Arctic Ocean to the Aleutians became exposed between northeast Asia and Alaska, and across that plain, most likely, walked the first people of the New World. This book describes what is known about these people and the now partly submerged land, named Beringia, which they settled during the final millennia of the Ice Age. Humans first occupied Beringia during a twilight period when rising sea levels had not yet caught up with warming climates. Although the land bridge between northeast Asia and Alaska was still present, warmer and wetter climates were rapidly transforming the Beringian steppe into shrub tundra. This volume synthesizes current research-some previously unpublished-on the archaeological sites and rapidly changing climates and biota of the period, suggesting that the absence of woody shrubs to help fire bone fuel may have been the barrier to earlier settlement, and that from the outset the Beringians developed a postglacial economy similar to that of later northern interior peoples. The book opens with a review of current research and the major problems and debates regarding the environment and archaeology of Beringia. It then describes Beringian environments and the controversies surrounding their interpretation; traces the evolving adaptations of early humans to the cold environments of northern Eurasia, which set the stage for the settlement of Beringia; and provides a detailed account of the archaeological record in three chapters, each of which is focused on a specific slice of time between 15,000 and 11,500 years ago. In conclusion, the authors present an interpretive summary of the human ecology of Beringia and discuss its relationship to the wider problem of the peopling of the New World.

Seit der Frühzeit des Menschen hat das Mittelmeer die Welt unserer Vorfahren nachhaltig geprägt. Der Archäologe Cyprian Broodbank entwirft ein grandioses historisches Panorama dieses Meeres – von den Tagen der ersten Begegnung der Hominiden mit dem neuen Lebensraum vor 1,5 Millionen Jahren bis zum Beginn der Klassischen Antike. Cyprian Broodbank führt uns an die Küsten des Mittelmeers und lässt die angrenzenden Kulturräume längst vergangener Epochen wieder lebendig werden. Gemeinsam mit ihm umrunden wir wieder und wieder das Mittelmeer und lernen die seit den Tagen der Jäger und Sammler aufblühenden Gesellschaften kennen. Wir begleiten die ersten Menschen, die sich bereits in Einbäumen auf die See wagten, besuchen Fischer, Bauern und Handwerker in ihren Dörfern und lernen die Machtzentren der Alten Welt kennen, deren Herrscher und Eliten Rohstoffe und andere Schätze aus „Übersee“ begehrten. Wir erkennen das immer engmaschigere Netz der Hochkulturen, das sich nach und nach über das Meer in der Mitte breitet, und sehen Handelsschiffe und Kriegsflotten, die von der Straße von Gibraltar bis nach Tyros und von Etrurien bis Alexandria das Mittelmeer durcheilen, um an dessen unfassbarem Reichtum teilzuhaben, von dem noch in unseren Tagen atemberaubende archäologische Zeugnisse künden.

The Periglacial Environment, Third Edition, provides an authoritative overview of the worldâ??s cold, non-glacial environments. Emphasis is placed upon the North American and Eurasian polar lowlands, but examples are also drawn from Antarctica, the Qinghai-Xizang (Tibet) Plateau, and the northern mid-latitudes. First published in 1976 and subsequently revised in 1996, the text has been the international standard for over 30 years. The Third Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes, and landforms that typify periglacial environments. The text is divided into four parts. Part One discusses the periglacial concept and its interactions with geomorphology, geocryology and Quaternary science. It also outlines the range and variability of periglacial climates and the degree to which landscapes are in geomorphic equilibrium with prevailing periglacial conditions. Part Two describes present-day terrain that is either underlain by permafrost or experiencing intense frost action. The roles played by cryogenic weathering, ground ice, mass wasting, running water, wind action, snow and ice, and coastal processes are systematically analysed. Part Three summarizes evidence for the existence of periglacial conditions during the cold periods of the Pleistocene, with special reference to the mid-latitudes of Europe and North America. Part Four illustrates the geotechnical problems associated with human activity and resource development in periglacial environments, and discusses the potential impact of global climate change in the northern high latitudes. This excellent textbook is an invaluable resource for second and third year undergraduate students of Physical Geography, Geology, Environmental Science and Earth Science. The Periglacial Environment, Third Edition is also an informative reading for professionals, researchers and lecturers working and teaching in the field.

Using the biblical flood as an example, Young contends that the church has not always handled evidence well in grappling with scientific matters and issues a call to biblical scholars to interpret the Genesis text more rigorously in light of current scientific knowledge.
