Prevalence and Fate of Antibiotic-resistant E. coli in Municipal Wastewater Treatment Plants across Oregon

Creator:: Khorshidi Zadeh, Marjan
Abstract:: Wastewater treatment plants are considered one of the main sources and reservoirs of antimicrobial resistance (AMR). This study investigated the prevalence of 8 different phenotypes of AMR, multi-drug resistant (MDR), and extended-spectrum beta-lactamases (ESBL) producing E. coli in 17 wastewater treatment plants across Oregon in winter and summer of 2019...

Post-dispersal seed fates in a Western Oregon native prairie

Creator:: Clark, Deborah L.
Abstract:: Knowledge of post-dispersal seed fates and other regeneration characteristics is crucial for predicting abundances and distributions of populations and, ultimately, community species composition and diversity. Seed fate studies, however, are rare primarily due to the difficulty of determining seed fates and causes of mortality. This thesis investigated post-dispersal seed fates...

Greater Sage-grouse conservation assessment and strategy for Oregon: A plan to maintain and enhance populations and habitat

Creator:: Hagen, Christian
Abstract:: Greater sage-grouse (Centrocercus urophasianus) were once found in most grassland and sagebrush (Artemisia spp.) habitats east of the Cascades in Oregon. European settlement and conversion of sagebrush steppe into agricultural production led to extirpation of the species in the Columbia Basin by the early part of the 1900s, but sagebrush...

Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

Creator:: Jetti, Rajesh R.
Abstract:: Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...

Field guide to riparian plant communities in northwestern Oregon

Creator:: USDA Forest Service Pacific Northwest Region, McCain, Cindy, Christy, John A., Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: This field guide combines classifications of common streamside plant communities and native freshwater wetland communities in Northwest Oregon. It is a condensed version of two separate works which are both available on the CD that accompanies this book. The information is also available for reference or to download as a...

Artificial means of distinguishing smooth-line map unit boundaries : an examination of Oregon soil survey maps

Creator:: Sun, Yulin
Abstract:: Soil is a complex living system with high heterogeneity, which makes locating soil map boundaries a challenge. In traditional soil survey, the placement of soil map boundaries relies largely (at least initially) on identifying the soil-forming factors of biota and topographic relief through stereo aerial photo pairs. Future soil survey...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...
