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....

Evaluating the Ecological Trade-Offs of Riparian Thinning for Stream Ecosystems in Second-Growth Redwood Forests of Northern California

Creator:: Roon, David A.
Abstract:: Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...

A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

Creator:: Li, Chang
Abstract:: Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...

Bacterial and Host Factors Contributing to Mycobacterium avium subspecies paratuberculosis Persistent Infection

Creator:: Phillips, Ida L.
Abstract:: Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne’s disease, a chronic granulomatous enteritis that plagues domestic and wild ruminants globally. During the silent stages of Johne’s disease, infected animals intermittently shed bacteria for years prior to clinical diagnosis during advanced disease stages. This strategy allows MAP to...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

Validity and Reliability of the Unsupervised, Isokinetic Three-Minute All-Out Cycling Test for Critical Power

Creator:: Bronson, Staci M.
Abstract:: PURPOSE: We tested the hypothesis that the unsupervised, isokinetic 3- minute all-out cycling test (3MT) would be a valid and reliable way to determine end power (EP) and work done above end power (WEP). Additionally, we hypothesized that EP would successfully demarcate between heavy and severe-intensity exercise and thus represent...

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...

Shrinkage study of high performance concrete for bridge decks

Creator:: Fu, Tengfei
Abstract:: In the field of civil infrastructure, bridge desks are typically constructed using high performance concrete (HPC). Concrete bridge decks demand qualities such as low permeability, high abrasion resistance, superior durability, and long design life. Over decades of field and laboratory experience, many HPC bridge decks have been found to be...

Breeding and genetics of lilacs and hardy hibiscus

Creator:: Lattier, Jason D.
Abstract:: Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...

Diffuse deformation patterns along the North American plate boundary zone, offshore western United States

Creator:: Chaytor, Jason D.
Abstract:: Plate boundaries are commonly regions of complex, diffuse deformation with the motion across the boundary accommodated by numerous structural systems, rather than being narrow, discrete zones of deformation. One such boundary occurs where the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates along the west...
