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,...

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

Creator:: 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...

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...

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...

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

Creator:: 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...

Environmental contaminants in male river otters collected from Oregon and Washington, 1994-99, with reproductive organ hypoplasia observed in otter males

Creator:: Grove, Robert Allan
Abstract:: A large number of river otter (Lontra canadensis) males were collected from areas of high and low contaminant concentrations throughout western Oregon and Washington during the fall and winter of 1994-99. Few significant non-reproductive organ morphometric differences were found in the large series of male otters collected, except for adrenal...

The Impact of World Literature in Secondary Schools in Oregon and Chile : A Comparative Case Study

Creator:: McFarland, Annette Catherine
Abstract:: The reading of world literature, literary works from cultures other than one’s own, offers an effective means of creating greater awareness and sensitivity towards others. Research on the subject makes it clear that world literature can help lay the groundwork for a sense of world citizenship in students. To what...

Quaking aspen persistence in three Oregon landscapes

Creator:: 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...

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

Creator:: 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...
