Sugar pine and western white pine are widely distributed, economically valuable, and ecologically important native tree species in North America. However, white pine blister rust (WPBR), caused by a non-native fungal pathogen, Cronartium ribicola J.C. Fisch. in Rabh., has substantially affected populations of these species. Cronartium is an obligate parasite,...
John Keats, as a principal figure in the Romantic
movement in Europe, reacted against the philosophy of the
Enlightenment. His poetry and letters are testament to his
distrust of, and resistance to, an ever increasingly
clinical and "reasonable" society. Keats's poetic thought--imaginative,
speculative, dialectic--is the antithesis of an
Enlightenment philosophy...

The classroom practices discussed in this thesis come slowly and at a "slant" to feminism through critical reading of texts, a practice that I call a (re)presentation of the silent women in texts. Given our patriarchal western culture, making meaning, and especially making sense, of the role and representations of...
In twentieth century America, women continue the age-old struggle for recognition
as whole, intelligent individuals, not just an "other," less hearty, less deserving
or less capable being than man. Sarah Grimke spoke of the inequalities over 150 years
ago during the abolitionist movement when she compiled her major arguments into...

Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...
The over-arching theme of this work is that soil data affect the performance and realism of vegetation models with particular focus on their ability to predict or explain disturbances such as fire or disease. We tested the sensitivity of the Excel version of the 3-PG model to soil properties and...

In recent years, studies dealing with temperature regulation,
temperature sensitivity, and physiological responses to temperature
in lizards and other reptiles have increased tremendously. It is
notable that snakes have been largely ignored in such studies. This
no doubt is due to their less direct relationship to ancestral endotherms.
However, problems...

scores and were divided...
Large equine facilities are comprised of many different departments (areas) that are necessary for the proper care and maintenance of horses. The placement of departments is often inefficient due to the slow growth of equine facilities. As a result, facility layout becomes a crucial aspect requiring explicit consideration because mandatory...
Three seismic refraction profiles obtained between 42°N and
43°N along the median valley of the Gorda Ridge, an active spreading
center, allow the computation of the velocity structure underlying the
valley. Wide angle reflections which appear on the seismic records
suggest the existence of a velocity inversion underlying layer 3...
Epigenetic mechanisms are important for control of plant development, and may play a particularly important role in trees given their long life cycles and distinctive and stable tissue types.
