Life History Trade-offs: The Effects of Habitat Selection on Columbian Black-tailed Deer Survival in Oregon

创造者:: Clark, Jessica S.
Abstract:: The assessment of habitat quality for wild populations requires evaluation of vital rates associated with the use of that habitat. Factors associated with bottom-up (forage) or top-down (predation) regulation and the relative contribution of these processes on ungulate populations are difficult to quantify, especially for a cryptic, but widely distributed...

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

创造者:: 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...

Elucidating Key Aspects of the Biology of Select Species of Snail-killing Flies (Diptera: Sciomyzidae) in Oregon

创造者:: Alzahrani, Fares
Abstract:: Members of the family Sciomyzidae, known as snail-killing or marsh flies, are unique amongst insects in that the vast majority of reared species feed exclusively on mollusks and as a result their biological control potential has been well documented in the scientific literature. However, in North America there is a...

Reconciling Working Landscapes on State and Federal Lands with Endangered Species Act Requirements: Emerging Governance Surrounding Beaver-Related Watershed Restoration in Oregon

创造者:: Pike-Urlacher, Zach R.
Abstract:: Reconciling working landscapes with Endangered Species Act (ESA) requirements is a vexing challenge playing out in watersheds across the western United States. Beaver-related watershed restoration (BRR) methodologies have the potential to reconcile competing demands for resource extraction and recovery of ESA-listed species by restoring ecosystem functionality more effectively and at...

Impacts of Policy and Environmental Change: Understanding Factors of Vulnerability and Resilience in the Face of Change in Oregon Fishing Communities

创造者:: Strawn, Astrea
Abstract:: Commercial fisheries are coupled human-natural systems that cross state borders and integrate private, public, academic sectors and interests. These systems integrate complicated relationships between coastal socioeconomics, resource management and environmental realms. Previous findings from West Coast-based studies have identified aging trends in commercial fisheries participation, commonly referred to as the...

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

创造者:: 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...

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

创造者:: 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...

Quaking aspen persistence in three Oregon landscapes

创造者:: Seager, S. Trent
Abstract:: Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...

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

创造者:: 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...
