متن کاملDoes Grazing Affect Regional Climate?
Before European settlement, the Great Plains of the United States contained vast herds of bison. These bison altered the landscape through their grazing. Measurement data of the disturbance that such grazing could produce, when scaled for the large population of bison, were used with a coupled atmospheric–ecosystem model to evaluate the likely effect that this grazing had on the growing season ...
متن کاملGeotechnical Interaction of Piled Raft Foundations: Two Case Studies
Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...
متن کاملExploring agent-level calculations of risk and returns in relation to observed land-use changes in the US Great Plains, 1870-1940.
Land-use change in the U.S. Great Plains since agricultural settlement in the second half of the nineteenth century has been well documented. While aggregate historical trends are easily tracked, the decision-making of individual farmers is difficult to reconstruct. We use an agent-based model to tell the history of the settlement of the West by simulating farm-level agricultural decision makin...
متن کاملVascular Plant Communities Associated with Black-tailed Prairie Dog Colonies in Southern Shortgrass Prairie
The black-tailed prairie dog (Cynomys ludovicianus), a large burrowing rodent found in grasslands of the western Great Plains, once occurred over approximately 40 million ha before European settlement (13). Prairie dogs (C. ludovicianus, C. leucurus, C. gunnisoni, and C. parvidens) covered approximately 283 million ha in the late 1800s Vascular Plant Communities Associated with Black-tailed Pra...
