Patterns Of Epiphytic Lichen Abundance On Aspen Stands In Proximity To Roads Of Varying Vehicular Traffic, D. Aragon, C. Castillo, J. Moffroid, G. Thomas
Aspen Bibliography
Although present in nearly any wild space with available moisture and on a wide variety of substrates, lichen, and its importance as a bioindicator for an ecosystem, is often overlooked. As air pollution becomes a greater concern for flora, fauna, and even humans, the story told by lichen growth becomes more useful as we try to make sense of the downstream effects of anthropogenic contributions to poor air quality. One such human-driven pollutant is the level of emissions that result from vehicular travel. The Jackson Hole area has experienced a large increase in vehicular traffic in the past five to …

Aspen Bibliography
The world's largest known clone of aspen (Populus tremuloides), called the "Pando Clone" is located in the Fishlake National Forest in central Utah. For many decades, significant pressure from ungulate (deer and cattle) browsing has prevented growth of young aspen stems in to trees that would replace the mature trees as they die of natural causes. There has been concern that this impressive 104-acre Pando Clone could be lost altogether due to the excessive browsing of young aspen stems. In 2013, 16 acres of this clone were fenced to exclude all ungulates (deer and cattle) so that recovery …

An Analysis Of Yield Variation Under Soil Conservation Practices, Andrew E. Anderson, W. Ashley Hammac, Diane E. Stott, Wallace E. Tyner
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Much attention has been paid to the effects of multiple soil conservation and soil health practices on the mean yield of the subsequent crop. Much less research has focused on the variability of crop yields over time or space. Yield stability reported in standard deviation, mean absolute deviation, or coefficient of variation can be an important measure of risk for producers. Risk reduction has economic value, and understanding the effect of tillage and other soil conservation practices on yield risk is relevant to farm financial management and crop insurance risk assessment. We used data from test plots in a corn …

Legacy Theses & Dissertations (2009 - 2024)
A wide range of managerial problems are similar in nature, and yet they continuously appear in different forms and in different geographical locations. Compared to other sciences, it seems that in the field of management, managers have a hard time facing these similar problems. Part of this issues is caused by the extreme complexity of the systems and another part is caused by the lack of a universal language with which managers can communicate their lessons. This dissertation offers a set of tools that have been previously manufactured in systems science, and more specifically in System Dynamics.
