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.

This book was released on 2012-04-06 with total page 751 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical and statistical methods have rapidly become part of a palaeolimnologist’s tool-kit. They are used to explore and summarise complex data, reconstruct past environmental variables from fossil assemblages, and test competing hypotheses about the causes of observed changes in lake biota through history. This book brings together a wide array of numerical and statistical techniques currently available for use in palaeolimnology and other branches of palaeoecology.

Available in PDF, EPUB and Kindle. Book excerpt: Written by leaders in the field of remote sensing information processing, this book covers the frontiers of remote sensors, especially with effective algorithms for signal/image processing and pattern recognition with remote sensing data. Sensor and data fusion issues, SAR images, hyperspectral images, and related special topics are also examined. Techniques making use of neural networks, wavelet transforms, and knowledge-based systems are emphasized. A special set of three chapters is devoted to seismic analysis and discrimination.In summary, the book provides an authoritative treatment of major topics in remote sensing information processing and defines new frontiers for these areas.

This book was released on 1990 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This atlas examines nearly every aspect of the natural history of the Nebraska Sand Hills, including Indian occupation, settlement, current range practices & the "cow-country" lifestyle. These 19,300 square miles comprise the largest dune area in the Western Hemisphere. The grass-stabilized dunes, some as high as 400 feet & as long as 20 miles, were formed by blowing sand during a surprisingly recent time, mostly the last 8,000 years. The climate ranges from subhumid in the east to semiarid in the west. The area is an ecological meeting ground, where species from different vegetative & faunal regions coexist, creating distinctive biological communities. The sandy soils & underlying sands & gravels have allowed for the accumulation of a vast quantity of groundwater, much of which "outcrops" at the surface. This accounts for another unique characteristic: the dry, dune-top prairie ecosystem beside a wetland, lake, or constantly flowing stream. "But this atlas is much more than an explanation of the climate & geology of the Sand Hills. Illustrated with wonderful color photos, fold-out maps, graphs & numerous charts, the book explores the entire ecology of the Sand Hills," said Francis Moul in his review for the DES MOINES REGISTER.
