Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sculpted by Ice written by Michael Collier and published by Alaska Natural History Association. This book was released on 2004 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ice once covered most of North America. Today, Alaska, with its approximately 100,000 glaciers, is a living example of its profound influence - the state's rugged landscape is a textbook of glacial activity, and geologist and photographer Michael Collier guides you through its pages. In the company of scientists studying this ancient ice, he approaches the great sleeping beasts on foot (crampons snugly strapped on), from a kayak (rocking gently in an icefall's wake), and from the air (through the window of a small plane). Follow him across the tricky terrain of glacial terms and geologic time - it's a journey well worth taking.

This book was released on 2014-09-02 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaska—America's forty-ninth state—has a long and rich history. Beginning with the Native people who first made their homes there, the inhabitants have benefited from Alaska's bountiful resources. Alaska's gold, fish, and lumber have all contributed to America's economy. Some people wonder, however, if Alaska's greatest natural resource might be her untouched wilderness areas. Our National Parks are another one of our great resources. How should land be used? To whom does it belong? Who should decide? Questions like these have played a major role in shaping the United States—and they continue to do so today. America's National Parks are just one answer to these questions.

Download or read book American Environmental History written by Carolyn Merchant and published by Columbia University Press. This book was released on 2007-10-31 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: By studying the many ways diverse peoples have changed, shaped, and conserved the natural world over time, environmental historians provide insight into humanity's unique relationship with nature and, more importantly, are better able to understand the origins of our current environmental crisis. Beginning with the precolonial land-use practice of Native Americans and concluding with our twenty-first century concerns over our global ecological crisis, American Environmental History addresses contentious issues such as the preservation of the wilderness, the expulsion of native peoples from national parks, and population growth, and considers the formative forces of gender, race, and class. Entries address a range of topics, from the impact of rice cultivation, slavery, and the growth of the automobile suburb to the effects of the Russian sea otter trade, Columbia River salmon fisheries, the environmental justice movement, and globalization. This illustrated reference is an essential companion for students interested in the ongoing transformation of the American landscape and the conflicts over its resources and conservation. It makes rich use of the tools and resources (climatic and geological data, court records, archaeological digs, and the writings of naturalists) that environmental historians rely on to conduct their research. The volume also includes a compendium of significant people, concepts, events, agencies, and legislation, and an extensive bibliography of critical films, books, and Web sites.
Download or read book Structure and Function of an Alpine Ecosystem written by William D. Bowman and published by Oxford University Press. This book was released on 2001-04-26 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will provide a complete overview of an alpine ecosystem, based on the long-term research conducted at the Niwot Ridge LTER. There is, at present, no general book on alpine ecology. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions, because it offers large environmental change over relatively short distances. Factors such as macroclimate, microclimate, soil conditions, biota, and various biological factors change on differing scales, allowing insight into the relative contributions of the different factors on ecological outcomes.
Download or read book Ice Age Extinction written by Jim Snook and published by Algora Publishing. This book was released on 2008 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author explores the causes of Earth's cyclical temperature changes and shows how those temperature shifts touch off a chain of events in the atmosphere, in the oceans and on land. Cold temperature was the trigger; and the resultant reduction in carbon dioxide, he argues, was the bullet that killed off so many species. The re-warming released more carbon dioxide into the atmosphere and fueled a resurgence. This book provides significant long term background information to put global warming into perspective. In addition, the author describes the human responses to increases in atmospheric carbon dioxide after the last ice age and in the last 150 years. Near the end of the last ice age, atmospheric carbon dioxide was about half of what it is today. Due to the lack of carbon dioxide, most of the vegetation disappeared from the middle and high latitudes. Without plants to eat, many large animals became extinct; North America lost three-fourths of its large animals including the woolly mammoth, mastodon and saber tooth cat. Humans, too, had little to eat in these areas and their population declined dramatically. The book then explains how and why atmospheric carbon dioxide increased by about 50% after the last ice age ended, encouraging a population explosion among plants, animals and humans, all of which then migrated into many previously barren areas. More recently, the 28% increase in atmospheric carbon dioxide in the last 150 years has caused a six-fold increase in the human population. Changes in the next 300 years will reverse some of the current trends. This book has value for anyone interested in the ice age extinction; glaciers; the glacial cycle; the atmosphere and oceans and the past and future of plants, animals and humans. It provides long-term information on atmospheric carbon dioxide, global warming and cooling.
