Seasonal Movement of Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) in Headwater Streams in Oregon

Creator:: Linkem, Christina N.
Abstract:: Headwater streams in the Oregon Coastal Range are subject to drastic fluctuations in flow and temperature because of the changing seasonality of a Mediterranean climate. In response to these changes, stream fishes exhibit a variety of movement patterns. Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) have evolved an assortment of life...

ATRIAS 1.0 & 2.1 : enabling agile biped locomotion with a template-driven approach to robot design

Creator:: Grimes, Jesse A.
Abstract:: Practical bipedal robots need to be simultaneously efficient, robust, and versatile machines, but designing robots dynamically capable of these demands has been a significant bottleneck. We designed ATRIAS to be a highly dynamic biped capable of both walking and running untethered in real environments. To meet these goals, ATRIAS is...

Force and impulse control for spring-mass running

Creator:: Koepl, Devin N.
Abstract:: We present a novel control strategy for running which is robust to disturbances, and makes excellent use of passive dynamics for energy economy. The motivation for our control strategy is based on observations of animals, which are able to economically walk and run over varying terrain and ground dynamics. It...

Modifications to Rearing Environments as a Method for Reducing Domestication Selection in Hatchery-reared Steelhead (Oncorhynchus mykiss)

Creator:: Obley, Miriam
Abstract:: Since the decline of salmonid populations in the Pacific Northwest, supplementation programs have become frequently implemented by hatcheries as a way to protect and conserve wild stock. However, hatchery-reared fish have lower fitness than wild fish which is likely due to adaptation to the hatchery environment, i.e., domestication selection. Fish...

Distinguishing Risk and Protective Factors for Suicidal Ideation and Attempt Among Gender Diverse and Cisgender Youth: Findings from a State Survey

Creator:: Zell, Holly
Abstract:: Suicide is a leading cause of death amongst adolescents, and transgender and gender diverse youth are at especially high risk for suicidal ideation and attempt compared with cisgender peers. Using established ideation-to-action models of suicide and the Minority Stress Model, this project used the 2019 results of the Oregon Healthy...

Mercury bioaccumulation in remote subalpine lakes : assessing the influence of invasive trout on salamanders

Creator:: Pfleeger, Adam
Abstract:: Mercury (Hg) contamination is a global conservation threat to freshwater ecosystems, detected in even the protected lakes of Olympic National Park (Washington, USA). Although considered some of the most remote and pristine US ecosystems, these lakes are currently subject to multiple environmental stressors, including climate change and fish introductions; adding...

SPEAR : Superlative Plagiarism Explorer And Reporter

Creator:: Pavithran, Siddharth
Abstract:: In this project, we have investigated three different techniques for plagiarism detection and have compared its effectiveness against that of an unaided human grader. The techniques investigated were word frequency analysis, sentence inclusion analysis and sub string inclusion analysis. We found that a combination of word frequency analysis and sub...

Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

Creator:: Hooper, Samuel
Abstract:: Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

Tempo and Mode of Diversification in the Neotropical Fish Superfamily Anostomoidea (Ostariophysi: Characiformes)

Creator:: Frable, Benjamin W.
Abstract:: Neotropical characiform fishes form one of the most diverse freshwater ichthyofauna in the world. Knowledge of evolutionary processes that generated and maintain the immense characiform lineage and morphological diversity is still poorly understood. When did characiform lineages diversify? How have major geological and environmental changes affected diversification? Why are some...

Assessing physical vulnerability of the coast in light of a changing climate : an integrated, multi-hazard, multi-timescale approach

Creator:: Harris, Erica L.
Abstract:: Hazards threaten coastal communities and ecosystems over a wide range of spatiotemporal scales. One of the most pressing concerns for coastal property owners, decision makers, and researchers is the uncertain role that a changing climate will have on the intensity and frequency of these hazards. The significant uncertainties associated with...
