The Upper Klamath Basin is an ecologically significant watershed that supports millions of migratory waterbirds along the Pacific Flyway in addition to an agricultural economy and a tribal fishery. This literature review and annotated bibliography is the basis for a capstone project to address the history, evolution, impacts, and responses...
Headwater riparian areas occupy a large proportion of the land base in Pacific Northwest forests, and thus are ecologically and economically important. Although a primary goal of management along small headwater streams is the protection of aquatic resources, streamside habitat also is important for many terrestrial wildlife species. However, mechanisms...

Bark beetle outbreaks have left a legacy of tree mortality across fire-prone landscapes of western North America that could influence how these forests will burn and regenerate. While research has been focused on forests in the western United States, the potential interactions between mountain pine beetle (MPB) outbreaks and wildfires...
European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and...
This study compared recidivism rates of adult male completers and non-completers
of correctional education programs in ABE/GED/high school, vocational, and
college transfer programs over a five-year period. A total of 1382 releasees was
studied for the five years following their release. Recidivism was the dependent
variable. Recidivism was defined as...
