Dynamics Of Western Juniper Woodland Expansion Into Sagebrush Communities In Central Oregon, Mary M. Rowland, Lowell H. Suring, Robin J. Tausch, Susan Geer, Michael J. Wisdom

Natural Resources and Environmental Issues

Western juniper (Juniperus occidentalis) woodlands in Oregon have expanded four-fold from 600,000 ha in 1930 to > 2.6 million ha, often resulting in the reduction and fragmentation of sagebrush (Artemisia spp.) communities. We documented dynamics of western juniper across the John Day Ecological Province in central Oregon by recording size class and growth form at 178 sites. We used stratified random sampling, with strata based on vegetation association (sagebrush, juniper, other) and distance from juniper stands. Only 26 percent of sites contained pre-settlement trees (in other words, > 140 years old), and < 5 percent of the 2,254 junipers tallied were pre-settlement trees. Mean densities of pre-settlement trees by stratum ranged from 0 to 18 trees/ha, suggesting that historically, juniper was widely scattered across the landscape. Current densities of post-settlement trees ranged from 75 to 211 trees/ha in non-woodland strata to 457 trees/ha in the juniper stratum. Juniper in non-woodland strata was most abundant in sites adjacent to juniper stands and in sagebrush communities. Mean densities of post-settlement trees were greatest in the > 2.0-m tall size class (82 trees/ha), followed by the 0.3 …

Oregon Aspen Project, Forest Restoration Partnership

Aspen Bibliography

The Oregon Aspen Project was initiated in response to the decline of aspen groves in Oregon and throughout the Western United States, and the lack of information to guide managers interested in stewardship to enhance this resource. There were three central goals and accompanying objectives for this project which are listed below. The project accomplishments are provided below each bulleted objective

Phonon Wave-Packet Simulations Of Ar/Kr Interfaces For Thermalrectification, Nick A. Roberts, D. G. Walker

Nick Roberts

The frequency and direction dependence of transmission coefficients at interfaces was investigated theoretically. The interfaces are formed by having two Lennard-Jones materials differing in mass and interatomic potential equally divided at the center of an fcc lattice system. A single frequency wave-packet is generated at one end of the system and allowed to propagate through the system until all interactions with the interface are complete. The transmission coefficient is then calculated by comparing the energy of the packet that is transmitted with the original wave-packet. Results show a difference in transmission when the wave-packet originates from opposite sides.

An Exploration Into How Physical Activity Data-Recording Devices Could Be Used In Computer-Supported Data Investigations, Victor R. Lee, Maneksha Dumont

Instructional Technology and Learning Sciences Faculty Publications

There is a great potential opportunity to use portable physical activity monitoring devices as data collection tools for educational purposes. Using one such device, we designed and implemented a weeklong workshop with high school students to test the utility of such technology. During that intervention, students performed data investigations of physical activity that culminated in the design and implementation of their own studies. In this paper, we explore some of the mathematical thinking that took place through a series of vignettes of a pair of students engaged in analyzing some of their own activity data. A personal connection to the …

The Role Of Discriminatory Experiences On Hispanic Students’ College Choice Decisions, Amanda Taggart, Gloria Crisp

Teacher Education and Leadership Faculty Publications

This study examined the impact of discriminatory experiences on Hispanic students’ decisions concerning postsecondary enrollment. Logistic regression was used to identify variables associated with Hispanic students’ decisions to attend either a 2- or a 4-year institution within the context of theory concerning college choice/success. Data were drawn from a nationally representative sample ( n = 2,210) of Hispanic students from the ELS:2002 data set. Results indicated that Hispanic students were less likely to attend a 4-year institution if they personally experienced or perceived others being discriminated against during high school. Findings suggest that discriminatory high school experiences may contribute to …

Information-Seeking Behavior Of Novelists In Archives, Cary G. Osborne

Journal of Western Archives

Archives are a frequently untapped resource for novelists. Accounts of daily life, the lives of individuals, details of specific eras, and other minutiae found in the documents and memorabilia housed in archives can be used to fill out the essential scenes and events of the stories. Such facts and personal details help fiction writers make their stories real to readers and keep misconceptions and factual errors out. This study looks at the limited literature on the subject of authors in archives and presents examples of the types of information housed in particular archives to illustrate the kinds of details that …

Uncertainty Associated With Modeling The Global Ionosphere, Janelle V. Jenniges, Ariel O. Acebal, Larry Gardner, Robert W. Schunk, Lie Zhu

Physics Student Research

A study has been conducted of the effect that different physical assumptions have on global models of the electron density distribution. The study was conducted with the Ionosphere Forecast Model (IFM) and the Ionosphere Plasmasphere Model (IPM) developed by Utah State University. Both physics-based, time-dependent, global models use the same empirical models for the neutral atmosphere (MSIS) and neutral wind (Horizontal Wind Model, HWM), but the altitude range, thermal structure, number of ion species, and magnetic 2ield are different. The IFM covers the altitude range from 90-1400 km, calculates the densities for four ions (NO+, O2+, N2+, O+), has a …

Estimating Expected Fire Suppression Cost Savings Due To Vegetation Management On Pinyon Pine And Juniper Invaded Sagebrush Rangelands, Kimberly Rollins, Mimako (Mimi) Kobayashi

Reports

Wildfire suppression costs in the United States have increased steadily over the last decades (Stephens and Ruth 2005, Calkin et al. 2005, Gebert et al 2007, Westerling et al. 2006, GAO 2007), with related expenditures by the U.S. Forest Service and Bureau of Land Management exceeding a billion dollars per year in four out of the seven years leading up to 2006 (Gebert et al 2008). Pre-­fire vegetation management on public lands is recognized as an important tool for reducing expected wildfire suppression costs (GAO 2007).Using data from wildfire suppression costs across the US, Lankoande and Yoder (2006) estimate that …
