Ecology and Conservation of Great Plains Vertebrates
Author: Fritz L. Knopf
Publisher: Springer Science & Business Media
ISBN: 1475727038
Category : Science
Languages : en
Pages : 329
Book Description
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.

Perspectives in Grassland Ecology
Author: N.R. French
Publisher: Springer Science & Business Media
ISBN: 1461261821
Category : Science
Languages : en
Pages : 215
Book Description
This volume is a result of the summary and synthesis of data collected in the Grassland Biome Program, which is part of the American contribution to the International Biological Program (IBP). The purpose of this volume is to present a summary of quantitative ecological investigations of North American grass lands and to present a set of broad comparisons of their characteristics and functions as well as the results of some models and experiments that lead to practical considerations of the management of grasslands. Synthesis is a continuing activity in science. Early in the Grassland Biome Program there was a synthesis of literature data on grasslands, edited by R. L. Dix and R. G. Beidleman (1969). Results of the first year of field data collection under this program were synthesized in a volume edited by N. R. French (1971). Development of the large-scale model constructed to depict the processes and the dynamics of state variables in grassland ecosystems was presented by Innis (1978). Soon to appear will be two volumes integrating studies of American grasslands with IBP studies in other grasslands of the world (Coupland, in press) and the application of systems analysis to understanding grassland function and utilization (Breymeyer and Van Dyne, in press). The present volume presents current results and comparisons of field investigations and experimental studies that were conducted under this program.
