Paleoecology of Beringia

Paleoecology of Beringia is the product of a symposium organized by its editors, sponsored by the Wenner-Gren Foundation for Anthropological Research, and held at the foundation's conference center in Burg Wartenstein, Austria, 8-17 June 1979.
The focus of this volume is on the paradox central to all studies of the unglaciated Arctic during the last Ice Age: that vertebrate fossils indicate that from 45,000 to 11,000 years BP an environment considerably more diverse and productive than the present one existed, whereas the botanical record, where it is not silent, supports a far more conservative appraisal of the region's ability to sustain any but the sparsest forms of plant and animal life.
The volume is organized into seven parts. Part 1 focuses on the paleogeography of the Beringia. The studies in Part 2 explore the ancient vegatation. Part 3 deals with the steppe-tundra concept and its application in Beringia. Part 4 examines the paleoclimate while Part 5 is devoted to the biology of surviving relatives of the Pleistocene ungulates. Part 6 takes up the presence of man in ancient Beringia. Part 7 assesses the paleoecology of Beringia during the last 40,000 years
