Impacts of Reduced Tillage and Disturbance on Soil Health and Microbial Community Dynamics in Grass Seed Cropping Systems

Creator:: Zamora, Cesar G.
Abstract:: In Oregon perennial and annual grass seed cropping systems conservation management practices and their impacts on soil health and soil microbial community is not well understood. There is strong motivation to employ conservation tillage and other conservation practices to curb atmospheric carbon levels and improve soil health. However, the few...

Turnover, Memory, Persistence: Four Decades of Ecological Community at Lost Valley

Creator:: Bruno, Mark P.
Abstract:: This study is an ethnographic investigation of residential turnover, organizational memory, and the persistence of Lost Valley, an Oregon ecovillage founded in 1989. Literature on organizational turnover, memory, and persistence is reviewed and integrated with scholarship on intentional communities and ecovillages, generating a theoretical framework for data collection and analysis....

Creating a Predictive Model of Cinder Cone Evolution in Central Oregon

Creator:: Das-Toke, Shyam P.
Abstract:: Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...

The Economic Path Dependency of Foreign Extraction Duration: Why Colonialism Still Matters

Creator:: Kemp, Duncan S.
Abstract:: Foreign occupation and extraction have arguably existed since the very emergence of interstate conflict millennia ago. Yet despite humanity’s vast experience on the topic, we know surprisingly little about its long-term economic consequences. It is generally accepted by most that the extraction of resources by a foreign power tends to...

Oregon’s Non-Consumptive Recreational Ocean User Community : Understanding an Ocean Stakeholder

Creator:: Eardley, Christopher S. and Conway, Flaxen D. L.
Abstract:: Oregon is in the midst of major changes to the way it manages use of the ocean off its shores. Consideration for all stakeholder groups will contribute to defensible decisions regarding the use of ocean and coastal resources. This relies on an understanding of the various stakeholders in ocean resources,...

Coastal cutthroat trout : life in the watershed

Creator:: Fitzpatrick, Martin S. and Oregon State University. Sea Grant College Program
Abstract:: Coastal cutthroat trout is one of three cutthroat subspecies found in Oregon. The coastal subspecies, which is closely related to steelhead/rainbow trout and Pacific salmon, displays the most diverse and flexible life history of any of the Oregon salmonids. Coastal cutthroat can be found in streams and rivers from the...

Learning to Teach Science from a Contextualized Stance

Creator:: L’Heureux, K., Giamellaro, M., Beaudry, M-C., Buxton, C., Ayotte-Beaudet, J-P., and Alajmi, T.
Abstract:: Contextualization is a curricular approach and a learning process in which science content knowledge is intentionally situated within a context where that knowledge can be authentically applied or observed. Many recent science education reforms include contextualization as a central tenet. Our goal in this review was to examine commonalities across...

Spatial patterns and trends of summertime low cloudiness for the Pacific Northwest, 1996-2017

Creator:: Dye, Alex W., Rastogi, Bharat, Clemesha, Rachel E. S., Kim, John B., Samelson, Roger M., Still, Christopher J., and Williams, A. Park
Abstract:: Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...

Silage corn (western Oregon) [2009]

Creator:: Hart, John M. (John Mervyn), 1947-, Sullivan, Dan M., Gamroth, Mike, Downing, Troy, Peters, Amy, and Oregon State University. Extension Service
Abstract:: Silage corn makes excellent feed for dairy cattle because of its high dry-matter yield, energy content, and palatability, especially when mixed with other feed. Also, it does not accumulate potassium as do many cool-season grass species. Nitrogen (N) is the most yield-limiting nutrient for silage corn production. Most dairies in...
