Vulnerability and adaptation of Pacific Northwest shellfisheries to ocean acidification

Creator:: Katz, Brian G.
Abstract:: The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...

Understanding Patterns of Timber Harvest and their Drivers : A Quantitative Assessment of Forest Governance in the Western Cascades of Oregon

Creator:: Harris, Tyler C.
Abstract:: Effective forest governance is central to the efficient, sustainable, and equitable use of forest resources, yet challenges in assessing forest governance impede efforts to improve it. Contemporary forest governance involves decisions by multiple stakeholders across multiple sectors of economy and society, from local to global scales – making forest governance...

Advancing Understanding of Changes in the Cryosphere of the Western United States and Alaska: A Case for the Importance of Spatial and Temporal Scaling

Creator:: Roberts-Pierel, Benjamin M.
Abstract:: The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...

Comparison and accuracy assessment of wetland land cover classification systems in the Willamette Valley, Oregon

Creator:: Lett, Christina L.
Abstract:: The purpose of this study was to better understand the level of wetland classification consistency among three different land cover layers created using Geographical Information System (GIS) and remote sensor technology. Where inconsistencies in data existed, the goal was to identify the kinds of inconsistencies that occur. The results were...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...

Nuclear Power Plant Siting in the Columbia River Basin: Current Trends, Effects of Climate Change, and Associated Uncertainties

Creator:: Savotkina, Alexandra A.
Abstract:: This PhD dissertation describes and evaluates a geographical analysis of candidate areas for siting nuclear plants utilizing a wet cooling tower in the Columbia River Basin (CRB). It focuses on the analysis of water availability for cooling and how it may be limited by climate change effects on river streamflow....

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Spatial and temporal patterns of windthrow in the Bull Run Watershed, Oregon

Creator:: Sinton, Diana Stuart
Abstract:: Throughout the 20th century, windthrow has affected forests in the Bull Run watershed, a 26,500 ha basin that is the principal water source for the city of Portland, Oregon. Windthrow from storms in 1973 and 1983 was mapped into a geographic information system (GIS) and compared to a 1931 windthrow...

Zooarchaeologjcal and Taphonomic Investigations of Site 35JA42, Upper Applegate River, Southwestern Oregon

Creator:: Schmitt, Dave N.
Abstract:: Site 35JA42 represents the first protohistoric village complex excavated in Southwest Oregon. Analyses of animal bones recovered from the site offer the first significant insights into human subsistence behaviors in this region. Although the faunal assemblage is extremely fragmented, detailed zooarchaeological analysis indicates that deer were the primary meat resource...

Soil mounds and patterned ground of the Lawrence Memorial Grassland Preserve

Creator:: Johnson, Colleen Burch
Abstract:: The Lawrence Memorial Grassland Preserve, located in Wasco County, Oregon, exhibits a wide variety of soil mounds and patterned ground features. The size, shape, and distribution of several elements of this peculiar landscape were analyzed with a detailed map, field observations, and statistical procedures. Common soil mound shapes are circular,...
