Book Description
Elias describes how the increased precipitation and cooler temperatures of the Pleistocene affected the desert environment. He also traces the impact of ancient cultures on the landscape, from the earliest inhabitants to the Anasazi.

Book Description
"During the last ice age, glaciers formed high in the Rocky Mountains and carved out the peaks and valleys visible today. Recreating the landscape and life forms of this era of the last great glaciations (from 10,000 to 125,000 years ago), this guidebook describes a little-known yet pivotal period in the ecological history of four western national parks: Glacier, Yellowstone, Grand Teton, and Rocky Mountain." "Scott A. Elias describes how great sheets of ice spread over and changed the shape of the land - forming the steep-walled valleys and braided rivers of Glacier National Park, the chain of so-called "pater noster" lakes in the lower Rockies, and the end moraines that dammed Jenny, Bradley, Taggart, and Phelps lakes in the Grand Teton park. Drawing on fossil evidence, he also introduces the large animals that thrived 21,000 years ago - dire wolves, short-faced bears, American cheetahs, and mammoths - and that quickly died off at the end of the last glaciation. He recounts the coming of humans to the region, the ascendance of the ecosystems we see today, and the lasting features (plant, animal and topographical) of the ice age." "This guidebook, along with its companion on the ice-age history of Alaskan national parks, relates as well the kinds of evidence and methods scientists use to recover past environments. Covering geology, climate, ancient plant and animal life, and human presence, Elias introduces paleoecology - the interactions among plants, animals, and the prehistoric ecosystem - to hikers, tourists, and armchair travelers."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
The demand for water resulting from massive population and economic growth in the southwestern U.S. overwhelmed traditional uses of riparian areas. As a consequence, many of these uniquely-structured ecosystems have been altered or destroyed. Within recent years people have become increasingly aware of the many uses and benefits of riparian zones a

Book Description
Focusing on more than 30,000 years of Alaskan prehistory, The Ice-Age History of Alaskan National Parks vividly describes the geology, climate, ancient plant and animal life, and human presence in four of Alaska's national parks and preserves - Denali, Kenai Fjords, Glacier Bay, and Bering Land Bridge. Scott A. Elias uncovers a time when glaciers shaped the landscape, gouging out valleys, carving cirques and peaks, and leaving moraines that blocked rivers and formed lakes. Using fossils as "witnesses" of past environments, he recreates the bogs and steppe tundra where caribou, moose, saber-toothed cats, and mammoths reigned 35,000 years ago. This guidebook presents a unique perspective for the modern traveler. Geared toward the general reader, it is the first in a series that will also survey the prehistory of the Rocky Mountain and Southwest national parks.

Book Description
The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Book Description
The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls
