All streams in Oregon that are inhabited by salmon and trout have a statemandated
water temperature standard. However, temperatures of many streams,
especially during summer months, exceed the seven-day average maximum
temperature parameter (200 C for redband trout inhabited streams) accepted by the
Oregon Department of Environmental Quality. To date,...
State-and-transition models (STMs) have been successfully used to
describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...
Abstract
DNA mismatch repair (MMR) plays an important role in preserving genomic stability and reducing cancer risk. Environmental exposures to polycyclic aromatic hydrocarbons (PAHs) are believed to contribute significantly to carcinogenesis. PAHs are found in food, air, water and soil and upon bioactivation can form diol epoxides which are electrophilic...

An undergraduate thesis
The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...
This work prepared YInMnO3, YCuTiO3, and YInFeO3 solid state pigments via microwave synthesis. The microwave-prepared pigments contain optical and structural properties similar to their furnace homologues. Overall synthesis times for each pigment have been significantly reduced via microwave synthesis, while keeping the same relative phase purity as solid-state.

Although community colleges have emphasized service-learning programs for traditional students, by in large, non-traditional students from post-secondary remedial programs have not been involved. This lack of reaching post-secondary remedial programs may be of particular interest to college personnel who may not be aware of the need to include service activities...
Best Management Practices (BMP) are widely used as a method for stormwater volume control in urban areas to prevent an overload of water on receiving water bodies and treatment facilities. BMPs ability to treat stormwater has gone under critical review in the last few decades, and their performance varies both...
On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary treatment method for such sites, however this method creates a potential fire hazard, particularly in the...
In an attempt to better understand documentary theory and production, I
created Bowling Together; a documentary recounting the experiences of one bowling
team and looking at the relationship between participation in bowling leagues and civil
society. This thesis provided me a first-hand experience at producing a documentary,
allowing me to...
