Diving into Diversity: Fish Populations and Climate Resilience in an Endorheic Basin

Creator:: Dew, Aleah
Abstract:: The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...

Spatial and Temporal Assessment of Vertically Migrating Myctophids as Biotransporters of Microplastics to Mesopelagic Food Webs

Creator:: Boisen, Olivia C.
Abstract:: It is well documented that microplastics and semi-synthetic particles (<5 mm) pervade the marine environment, with their ingestion by marine fauna eliciting global concern. While fishes exposed to microparticles in a laboratory setting have exhibited both sub-lethal and lethal effects, the diversity in material, morphology, and size of these contaminants...

Red tree voles in fragmented forests

Creator:: Piasecki, Jason T.
Abstract:: The red tree vole (Arborimus longicaudus) is an arboreal Arvicoline rodent endemic to conifer dominated forests of western Oregon and northwestern California. While commonly associated with old forests, often inhabiting stands over 80 years old, tree voles have also been found in young forests between 20 and 80 years old....

Use of Landscape Characteristics to Quantify Hybridization Risk Between Native and Introduced Salmonids

Creator:: Manning, Michael A.
Abstract:: The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...

Understanding the economic benefits of tidal wetlands restoration

Creator:: Shaw, Graham R.
Abstract:: Habitat restoration projects are vital for recovering ecosystems, but they can be expensive. One way to help justify the price tag is to value the economic benefits provided by the restored habitat. The issue is that many ecosystem services and the flow of benefits they produce are complex, requiring careful...

Evaluating the Impact of Organic Chromium with Flaxseed in Broiler Diets: Effects on Production Performance, Breast Muscle Pathology and Meat Quality Aspects

Creator:: Fraz, Ahmad
Abstract:: This study investigated the impact of organic chromium (Cr) supplementation and flaxseed on live performance, carcass yield, serum metabolites, muscle lipid profile, histopathological aspects, and meat quality parameters. Ninety (n=90), day-old Cobb chicks were fed a corn-soybean meal-based diet containing 0% flaxseed (Control), 10% flaxseed (Diet 1) and Diet 1...

Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

Creator:: Boring, Emily L.
Abstract:: Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...

Mid-Nineteenth Century Clay Smoking Pipes from Fort Hoskins (35BE15) and Fort Yamhill (35PO75), Oregon

Creator:: Zentgraf, Diane M.
Abstract:: Over the past 42 years clay smoking pipes have been excavated from two U.S. army posts, Fort Hoskins (35BE15) and Fort Yamhill (35PO75) and curated at Oregon State University. These two forts were established in Western Oregon in 1856 and by 1866 both had been decommissioned. Numerous theses have focused...

Subsistence Harvest Diversity in Alaskan Food Sharing Networks

Creator:: Scaggs, Shane A.
Abstract:: Two striking characteristics of human beings are the diversity of resources that we use to sustain our lives and the extent to which we engage in coordinated, collective efforts to obtain and consume these resources. Together, these two characteristics are the foundation of human subsistence patterns. In many remote Alaskan...

Movement, dive behavior, and habitat-use of common murres (Uria aalge) in the Northern California Current System under variable ocean conditions

Creator:: Loredo, Stephanie A.
Abstract:: Year-round habitat use of marine predators provides knowledge of important marine areas throughout different life stages. Large-scale, environmental variability, both in space and time, causes changes in the behavior and distribution of marine predators that are important to quantify for conservation. In the Northern California Current System (NCCS), common murres...
