Quantifying C and N contents and isotope signatures of SOM pools in the H. J. Andrews DIRT plots

Creator:: Keirstead, Heath
Abstract:: The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

For the Purpose of Power: An Analysis of George W. Bush’s Warrantless Wiretapping Address

Creator:: Owens, Michael V.
Abstract:: The purpose of this study is to examine the rhetorical efforts of President George W. Bush in defending his administration's warrantless wiretapping program. Specifically, the study attempts to determine the president's underlying motives when he defended the National Security Agency in a December 2005 radio address by applying Kenneth Burke's...

Characterizing spin-orbit torques in β-W/Ta/CoFeB/MgO devices

Creator:: Allen, Shane R.
Abstract:: Materials with a strong spin Hall effect and Rashba-Edelstein effect have the potential to improve the efficiency of solid-state magnetic memory technologies and other magnetic logic devices. Heavy metals have been identified as having these properties, including the beta crystal phase of tungsten. In this work, we determine the strength...

Changing Storms and Snowpack Fate in the Western United States

Creator:: Hu, Jyun-Yi Michelle
Abstract:: Cold-season storms are responsible for generating most of the snow that accumulates in mountainous watersheds across the western United States, but with overwhelming evidence of warming temperature trends, this seasonal snowpack is at risk for melt, The vast majority of snow trend studies utilize undifferentiated air temperature records – these...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Physical and chemical factors controlling the distribution of the major phytoplankton classes at the Antarctic Polar Front, 170 °W

Creator:: Mengelt, Claudia
Abstract:: This study was part of the Antarctic Environment and Southern Ocean Study (AESOPS) program, whose main goal was to investigate the role of the biota in the carbon flux from the atmosphere to the interior of the ocean. We quantified the abundance of the major phytoplankton classes and examined the...

Why Use Ankles? An Optimization Approach to Discover Energetic Benefits of Ankles in Steady Locomotion

Creator:: Hector, Michael J.
Abstract:: Design and control of legged robots is a popular field in the pursuit of building robots that can be as mobile as humans. While much effort is put into understanding how to control the dynamics of these legs, less effort is focused on designing and controlling robot ankles. Ankles on...

Glacier change in a basin of the Peruvian Andes and implications for water resources

Creator:: Burns, Patrick J.
Abstract:: Declines in glacier area and volume are widespread. These changes will have important hydrologic consequences since glaciers store tremendous amounts of fresh water and buffer seasonally low flows in many densely populated regions. In this thesis I focus on a region that is hydrologically vulnerable to glacier change, namely the...

Development and Evaluation of a Static Land-Based Aquaculture System for Pacific Dulse (Devaleraea mollis): Environmental and Nutrient Requirements

Creator:: Chatfield, Marcus W.
Abstract:: Devaleraea mollis (Pacific Dulse) is becoming a popular food for human consumption. Previously, Pacific Dulse has been used as a nutrient source for cultured abalone species, with some historical food use by indigenous peoples, while the closely related Atlantic dulse (Palmaria palmata) has a long-documented history of use in cuisine...
