Available in PDF, EPUB and Kindle. Book excerpt: The Nebraska Sandhills is the largest area of sand dunes in the western hemisphere, covering an area about as large as Vermont, New Hampshire, and Rhode Island combined. Unlike most dunes, the Sandhills region supports an astonishing variety of wildlife. Sixty million years ago the area lay submerged in a vast inland sea. As the land lifted and the waters receded, the sandhills were formed, built upon a sandy floor above a sandy basement. Paul A. Johnsgard's appreciation for the region includes its evolution, a process that continues today making a very special place, patiently shaped by water, wind, and time. Sometimes 450 feet higher than their sloping valleys, the hills themselves are almost entirely covered with plants that manage to survive on an unstable substrate and in a climate of merciless heat and cold. They provide homes and resting places for rare species and sustain the livelihoods of a remarkable variety of people. Though firmly established in science, this book is an extended love letter to the Sandhills region and its people, plants, and animals. Johnsgard is now in his third decade of research in the Sandhills. This Fragile Land lets others see what he sees, a land with a fascinating range of geological, biological, and ecological vistas. Paul A. Johnsgard is Foundation Professor of the School of Biological Sciences at the University of Nebraska-Lincoln. Widely published throughout the English-speaking world, he has become a foremost authority on ornithology and bird behavior. His thirty-three books include Birds of the Great Plains, The Platte, Birds of the Rocky Mountains, Those of the Gray Wind, and Diving Birds of North America, all available from the University ofNebraska Press.

Download or read book Ecology and Conservation of Great Plains Vertebrates written by Fritz L. Knopf and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains.
Download or read book Plant Geography written by Rexford Daubenmire and published by Elsevier. This book was released on 2012-12-02 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Geography: With Special Reference to North America covers main concepts of the two major approaches to plant geography, namely, the floristic plant geography and the ecologic plant geography. Floristic plant geography primarily studies evolutionary divergence, migration, and decline of taxa, as influenced by past events of the earth's history. Ecologic plant geography is an alternative approach to plant geography, which takes plant communities as units having ranges to be interpreted, dominated by sociologic and physiologic, rather than phylogenetic and historic considerations. Under the floristic plant geography part, topics covered include interrelations among floristic plant geography, taxonomy, and geology; the relation between plant dissemination and migration; evidence of the dynamic character of plant ranges; and migratory route. After a brief introduction to the evolution of North and South America vegetation, the book discusses the ecologic plant geography section that focuses on various vegetation regions in North America, including Tundra, subarctic-subalpine forest, temperate mesophytic, xerophytic forest, and chaparral and steppe regions and temperate affinity forests in Middle America. Other regions examined include the desert and marine regions, as well as the microphyllous woodland, tropical savanna, rain forest, and tropical alpine. With great information on geologic history of each vegetation unit and paleontology, this book will be helpful to paleobotanists, historical geologists, and taxonomists.
