Developing techniques for evaluating the susceptibility of root-disease resistant Port-Orford-Cedar to foliar and stem canker diseases.

Creator:: Martin, Danielle K. H.
Abstract:: Since around 1923 Port-Orford-cedar (Chamaecyparis lawsoniana (A. Murray) Parl.) has been affected by Phytophthora root disease caused by the virulent introduced pathogen Phytophthora lateralis. A systematic resistance testing and breeding program located at the USDA Forest Service Dorena Genetic Resource Center in Cottage Grove, Oregon was initiated in 1997 with...

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...

Oregon Greater Sage-Grouse Population Monitoring: 2017 Annual Report

Creator:: Foster, Lee
Abstract:: During the 2017 greater sage-grouse (Centrocercus urophasianus) breeding season, 1,580 aerial and ground lek surveys were conducted at 674 individual lek sites comprising 429 lek complexes. Surveys were conducted at 58.0% of known lek sites in the state. Survey effort during 2017 declined -17.1%, -12.2%, and 14.5% from 2016 levels,...

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...

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...

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...
