Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...
Black vine weevil (BVW), Otiorhynchus sulcatus Fabricius, is a serious pest in cranberry, Vaccinium macrocarpon. Larvae feeding below the soil surface cause damage to the roots and underground stems. Knowledge is sparse in regard to the damage potential of BVW in Pacific Northwest cranberry beds. Control with insecticides is limited...
Marine and coastal sedimentary archives show that the Cascadia Subduction Zone can generate great earthquakes of ~M9, most recently in 1700 CE, yet we still know little of the impacts of these events inland of the Pacific coast. Inland lakes have recently been exploited for their use as paleoseismic records...
This work sought to characterize a link between Vitamin C and nitroglycerin at the level of enzymatic bioactivation. Before we could proceed, we needed to develop a method that sensitively and selectively identified the product of bioactivation, nitrite. We successfully adapted traditional diaminonaphthalene derivatization with the use of stable isotope...
The central purpose of this research was to investigate the relationship of
locus of control and academic success in selected medical office assisting students.
The instrument for locus of control assessment was the Adult Nowicki-Strickland
Internal-External Scale (ANSIES). Structured interviews were used to elicit
personal responses for the purpose of...
Organizational culture is broadly recognized as a significant force in organizational
action. Since the phenomenon of culture has real impact on organizations, our understanding
of that impact is vital to organizational health. While academic settings provide a rich
environment for studying culture, relatively little research on culture has occurred in...
Endemic populations of pandora moths (Co/oradia pandora Blake), a defoliator of western pine forests, proliferated to epidemic levels in central Oregon in 1986 and increased dramatically through 1 994. Golden-mantled ground squirrels (Spermophilus lateralis Say) consume adult pandora moths, but reject nutritionally valuable eggs from gravid females. Feeding trials with...
Effects of small-scale disturbances on fecundity and growth rates of Linnaea
borealis L., Tiarella trifoliata L. var. unifoliata, and Trillium ovatum Pursh. were studied in
old-growth forests in the Tsuga heterophylla Zone on the west slope of the Cascade
Mountain Range of Oregon. Performance of each species was compared in...
