Factors affecting the regrowth of Himalya (sic) blackberry (Rubus armeniacus)

Creator:: Jones, Daniel Karl
Abstract:: Himalaya blackberry (Rubus armeniacus) is a widespread, exotic, invasive plant now common over much of western Oregon and Washington. An observational experiment revealed that disturbance to a monoculture of Himalaya blackberry allows the soil seed bank to be expressed and return the inhabited area to an earlier successional stage. This...

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:: Lake, Frank K.
Abstract:: The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...

Characterizing the neutron spectra in various irradiation facilities within the Oregon State University TRIGA ® Reactor

Creator:: Ashbaker, Eric
Abstract:: The Oregon State University TRIGA® Reactor (OSTR) has a number of irradiation facilities providing a wide range of neutron energies and fluxes. These facilities include a pneumatic transfer tube, a rotating rack, a thermal column, four beam ports, in-core irradiation tubes, a clyogenic gas transfer system and a large vault...

In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

Creator:: Stocking, Peter
Abstract:: Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

Geomorphic controls on hyporheic exchange flow in mountain streams

Creator:: Kasahara, Tamao
Abstract:: Simulations of stream-subsurface water exchange (hyporheic exchange) using a three-dimensional steady state groundwater flow model and a particle tracking model in unconstrained and constrained reaches of small (2nd-order) and intermediate (5th-order) mountain streams were conducted to estimate the effects of geomorphic features on the extent, volume and residence time of...

Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

Creator:: Li, Jingyi
Abstract:: Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

The phytotoxic effects of herbicide and adjuvant application by physiological timing on the woody shrub salal (Gaultheria shallon)

Creator:: Downs, Theodore
Abstract:: Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Usability Testing to Improve a Teaching Website for Graduate Counselor Education Students

Creator:: McMillen, Paula S., Pehrsson, Dale Elizabeth, and Lin, Shao-Chen
Abstract:: Expectations for technology proficiency in counseling and counselor education have increased; nevertheless, very little information is available in the counseling literature which describes how to effectively evaluate online resources from a design and utility standpoint. This study provides a model for such assessments, employing an affordable small scale usability study...

Analysis of hydrology and erosion in small, paired watersheds in a juniper-sagebrush area of central Oregon

Creator:: Fisher, Michael, (Michael Patrick), 1966-
Abstract:: Current research indicates that the expansion of western juniper can inhibit soil water retention, storage and prolonged releases from watersheds. This phenomenon is of great importance in eastern Oregon, as western juniper is encroaching into sagebrush/grass communities with a correlated reduction in herbaceous ground cover, resulting in reduced infiltration rates...
