Responses of juvenile coho salmon and larval lamprey to instream habitat restoration in a Pacific Northwest stream

Creator:: Gonzalez, Rosalinda
Abstract:: Large wood has been utilized in many restoration projects to improve in-stream habitat in the Pacific Northwest for salmon. However, the benefits of this practice remain the subject of ongoing debate and evaluation of these projects has scarcely been done for non-salmonid species such as lamprey. In this study we...

The Examination of Escherichia coli Contamination via Agricultural Water Applications and Survival During Pre-Harvest Field Curing of Dry Bulb Onions

Creator:: Racine, Jason R.
Abstract:: 2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...

The Victory in Vietnam Committee's Manichean Rhetoric : An Analysis of the Campaign to Recall Idaho Senator Frank Church

Creator:: Andrews, Cheri L.
Abstract:: The purpose of this study is to illuminate the role, the function, and the ironic outcome of the Victory in Vietnam Committee's campaign pamphlet to recall Senator Frank Church of Idaho in 1967. The VVC's political strategy was to build credibility with the media through the recall pamphlet. The analysis...

Assessing Durability of Concrete and Ettringite Accelerated Cementitious System

Creator:: Sarkar, Anika T.
Abstract:: The goal of the first part of this project was to investigate the influence of aggregate source and entrained air on the transport properties of concrete. Currently, there are several ASTM standards available that provide systematic procedures to evaluate mass transport properties of concrete. ASTM C642-13 (ASTM 2013), often referred...

Effects of Synchronous Low Flow and Temperature Maxima on Coastal Cutthroat Trout and Coastal Giant Salamander: An Experimental Approach

Creator:: Tinoco Pickens, Francisco Andrew
Abstract:: As regional climates warm in the Pacific Northwest, USA, flow minima and temperature maxima may become more synchronous in headwater streams over time. The dual stresses from lower flows and warmer temperatures will be energetically costly for cold-water species such as Coastal Cutthroat Trout and Coastal Giant Salamander. Individual fates...

Evolution of aposematic warning coloration in parasitic wasps (Hymenoptera:Braconidae)

Creator:: Leathers, Jason Wayne
Abstract:: Many Hymenoptera, with their painful stings and noxious chemical defenses, exhibit bright aposematic warning color patterns and are the most frequently mimicked group of organisms. Such aposematic color patterns are found in parasitic wasps of the Neotropical Compsobracon group (Braconidae). Many members of this group exhibit color patterns similar to...

Influences of Thermal and Trophic Heterogeneity on Phenology, Growth, and Resource Use by Juvenile Coho Salmon

Creator:: Campbell, Emily Y.
Abstract:: Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Subcultures of Significance: Urbanity-Rurality, Tightness-Looseness, and Risk Perception

Creator:: Frydenlund, Nicole T. L.
Abstract:: Tightness-looseness (TL) is a cultural construct that measures the level of social norms present in a community, and the level of scrutiny of deviance from these norms. This construct offers a unique foundation for investigating how norms influence behavioral processes. Research in TL is relatively young, creating a frontier of...

Seasonal variability in diet and consumption by cottid and salmonid fishes in headwater streams in western Oregon, USA

Creator:: Raggon, Mark F.
Abstract:: Coastal cutthroat trout (Oncorhynchus clarkii clarkii) and cottids (Cottus spp) commonly co-occur in headwater streams in western Oregon. Little is known about the comparative trophic ecology of these species or how they respond to seasonal scarcity of resources. In this study I evaluated the seasonal variability in diets and consumption...
