Relative influence of trans-Pacific and regional atmospheric transport of polycyclic aromatic hydrocarbons (PAHs) in the Pacific Northwest (PNW), USA

Creator:: Lafontaine, Scott
Abstract:: The relative influences of trans-Pacific and regional atmospheric transport on measured concentrations of polycyclic aromatic hydrocarbons (PAHs), PAH derivatives [Nitro- (NPAH) and Oxy-(OPAH)], organic carbon (OC), and Particulate Matter (PM) less than 2.5 μm in diameter (PM₂.₅) were investigated in the Pacific Northwest, USA in 2010-2011. Ambient high volume PM₂.₅...

Cost-efficient management of aquatic invasive species : application to New Zealand mudsnails in the Pacific Northwest

Creator:: Lim, Youngah
Abstract:: By affecting the ecological, pecuniary and aesthetic productivity of ecosystems, invasive species (IS) increase production and management costs to business, while straining public agencies' budgets with monitoring, enforcement and management efforts. Understanding invasion pathways or vectors, and identifying costs and benefits of alternative management strategies are critical to public and...

Trait-based approaches to linking vegetation and food webs in early-seral forests of the Pacific Northwest

Creator:: Campbell, John L. and Donato, Daniel C.
Abstract:: Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...

Re-examining Ceratomyxa shasta in the Pacific Northwest

Creator:: Stinson, Matthew E. T.
Abstract:: Ceratomyxa shasta infects salmonids in the Pacific Northwest (PNW) of North America, occasionally causing losses in wild and captive populations. Host-specific parasite genotypes (O, I, II, III) were previously characterized molecularly using markers in the ribosomal DNA and phenotypically by type host in the Klamath River, CA/OR. This thesis sough...

Utilization of the Non-Native Seagrass, Zostera japonica, by Crab and Fish in Pacific Northwest Estuaries

Creator:: Sund, Daniel M.
Abstract:: The introduction of non-native species often results in fundamental changes in the structure and function of disturbed environments. In the Pacific Northwest (PNW), the introduced seagrass Zostera japonica is rapidly expanding in distribution, impacting stakeholders and public use of the intertidal. Z. japonica’s expansion has prompted a number of different...

Survival and Home-range Size of Northern Spotted Owls in Southwestern Oregon

Creator:: Schilling, Jason W., Dugger, Katie M., and Anthony, Robert G.
Abstract:: In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...

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...

Competition release and climate change effects on a moisture-demanding tree species in a dry system

Creator:: Seager, S. Trent
Abstract:: Climate change and the increase in meteorological drought have generated global concern over the persistence of ecosystems already in decline from decreased moisture. Evidence suggests dryland ecosystems have been more impacted by drought because of their tightly coupled growth-water relationships and high sensitivity to environmental shift. Removal of competing vegetation...

Multi-hazard framework and analysis of soil-bridge systems : long duration earthquake and tsunami loading

Creator:: Carey, Trevor J.
Abstract:: During the 2011 Great East Japan Earthquake and Tsunami, numerous bridge structures were damage or destroyed. The damage to bridge systems was caused by long duration strong ground shaking, tsunami inundation forces, or both. Long duration strong ground shaking from subduction zone earthquakes and the multi-hazard scenario of combined earthquake...

Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

Creator:: Buffington, Kevin J.
Abstract:: Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...
