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.

Where the eastern and western currents of American life merge as smoothly as one river flows into another is a place called Nebraska. There we find the Platte, a river that gave sustenance to the countless migrants who once trudged westward along the Mormon and Oregon trails. We find the Sandhills, a vast region of sandy grassland that represents the largest area of dunes and the grandest and least disturbed region of mixed-grass prairies in all the Western Hemisphere. And, below it all, we find the Ogallala aquifer, the largest potential source of unpolluted water anywhere. ø These ecological treasures are all part of the nature of Nebraska. With characteristic clarity, energy, and charm, Paul A. Johnsgard guides us through Nebraska?s incredible biodiversity, introducing us to each ecosystem and the flora and fauna it sustains and inviting us to contemplate the purpose and secrets of the natural world as we consider our own roles and responsibilities in our connection with it.

Grouse—an ecologically important group of birds that include capercaillie, prairie chickens, and ptarmigan—are distributed throughout the forests, grasslands, and tundra of Europe, Asia, and North America. Today, many grouse populations are in decline, and the conservation and management of these charismatic birds is becoming a global concern. This volume summarizes current knowledge of grouse biology in 25 chapters contributed by 80 researchers from field studies around the world. Organized in four sections—Spatial Ecology, Habitat Relationships, Population Biology, and Conservation and Management—the chapters offer important insights into spatial requirements, movements, and demography of grouse. Much of the research employs emerging tools in ecology that span biogeochemistry, molecular genetics, endocrinology, radio-telemetry, and remote sensing. The chapters explore topics including the impacts of climate change, energy development, and harvest, and give new evidence for life-history changes in response to human activities.

An illustrated review of the Northern Great Plains that blends natural history and human history "The most complete, in-depth look at Dakota ecosystems and their history. An absolutely fascinating read!"--Gabe Brown, author of Dirt to Soil W. Carter Johnson and Dennis H. Knight describe the natural and human histories of the Northern Great Plains in this comprehensive and handsomely illustrated book. Covering a vast period of time, they move from geological developments millions of years ago and the effects of glaciers to historical and ecological developments in recent centuries and the effects of agriculture. The book ends with a discussion of the future of this region, mediated by climate change, with recommendations on how to balance agriculture and other pressing needs in the twenty-first century. Johnson and Knight bring decades of experience to chapters on the major ecosystems of the Dakotas. Written for readers with varying backgrounds, and with discussions of the Prairie Pothole Region, the Missouri River, grasslands, woodlands, the Black Hills, and rivers, lakes, and wetlands, the book is unique and will become a long-lasting source of information. Readers will appreciate the plentiful photographs and other color illustrations.

In Wildlife of Nebraska: A Natural History, Paul A. Johnsgard surveys the variety and biology of more than six hundred Nebraska species. Narrative accounts describe the ecology and biology of the state's birds, its mammals, and its reptiles and amphibians, summarizing the abundance, distributions, and habitats of this wildlife. To provide an introduction to the state's major ecosystems, climate, and topography, Johnsgard examines major public-access natural areas, including national monuments, wildlife refuges and grasslands, state parks and wildlife management areas, and nature preserves. Including more than thirty-five line drawings by the author along with physiographic, ecological, and historical maps, Wildlife of Nebraska is an essential guide to the wildlife of the Cornhusker State.

Human impact on natural landscapes through urbanization and agricultural expansion are becoming more and more dramatic and are the cause of serious environmental problems. This volume examines the effect of landscape disturbance on plant and animal diversity in the five mediterranean-climate regions of the world. It begins with three introductory chapters broadly reviewing the issues of landscape degradation. Further contributions describe regional land use conflicts in each of the five regions. Landscape disturbance and plant diversity, and landscape disturbance and animal diversity are treated in separate chapters. Four contributions deal with demography and ecophysiology in vegetation succession following disturbance. The volume closes with a consideration of the future addressing aspects of environmental politics.

Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea level do not lie within a drainage basin. Even points distant from the nearest channel are likely to be influenced by that channel. Tectonic uplift raises rock thousands of meters above sea level. Precipitation falling on the uplifted terrain concentrates into channels that carry sediment downward to the oceans and influence the steepness of adjacent hill slopes by governing the rate at which the landscape incises. Rivers migrate laterally across lowlands, creating a complex topography of terraces, floodplain wetlands and channels. Subtle differences in elevation, grain size, and soil moisture across this topography control the movement of ground water and the distribution of plants and animals. Rivers in the Landscape, Second Edition, emphasizes general principles and conceptual models, as well as concrete examples of each topic drawn from the extensive literature on river process and form. The book is suitable for use as a course text or a general reference on rivers. Aimed at advanced undergraduate students, graduate students, and professionals looking for a concise summary of physical aspects of rivers, Rivers in the Landscape is designed to: emphasize the connectivity between rivers and the greater landscape by explicitly considering the interactions between rivers and tectonics, climate, biota, and human activities; provide a concise summary of the current state of knowledge for physical process and form in rivers; reflect the diversity of river environments, from mountainous, headwater channels to large, lowland, floodplain rivers and from the arctic to the tropics; reflect the diverse methods that scientists use to characterize and understand river process and form, including remote sensing, field measurements, physical experiments, and numerical simulations; reflect the increasing emphasis on quantification in fluvial geomorphology and the study of Earth surfaces in general; provide both an introduction to the classic, foundational papers on each topic, and a guide to the latest, particularly insightful and integrative references.
