Invasive bullfrog use of novel ephemeral habitats in the Pacific Northwest

Creator:: Cook, Megan Tetsuko
Abstract:: Invasive species are a major threat to global biodiversity. Understanding the mechanisms underlying successful invasions is imperative for developing effective management strategies. Plasticity in physiological, morphological, and behavioral traits could be an indicator of invasion potential in non-native species. The invasive American bullfrog (Lithobates catesbeianus) has recently been observed breeding...

Role of the Sisters Fault Zone in the Separation of Siletzia from the Cascadia Backarc

Creator:: Mark-Moser, MacKenzie
Abstract:: Oblique subduction of the Juan de Fuca plate beneath the North American plate characterizes the tectonic setting of the Pacific Northwest. North American plate deformation at the latitude of central Oregon consists of the clockwise-rotation of the Siletzia block in the forearc and the extensional Basin and Range province in...

Predicting Treatment Options for the Intervertebral Disc: Patient-Specific Finite Element Models

Creator:: Ahrens, Sonia R.
Abstract:: This work describes a method for incorporating patient data into a nutrient transport model of the intervertebral disc.This data was collected using MRI diffusion weighted imaging (DWI), and was converted into an apparent diffusion coefficient map (ADC map). This map was used to define the diffusion behavior of water within...

User interface design considerations for emerging input technologies in iTV

Creator:: Wolford, Justin
Abstract:: Streaming media and interactive television viewing experiences are becoming more commonplace with the introduction of services such as Netflix Streaming, the Apple TV, and Google TV aided by the increase adoption of broadband internet. As these services make their way into the living room, and developers struggle to accommodate more...

An Experimental and Analytical Investigation of the Parameters that Influence Measured CO₂ in Plagioclase-Hosted Melt Inclusions in MORBs

Creator:: Drignon, Melissa J.
Abstract:: To understand the processes that lead to the formation of the oceanic crust, one must know the composition and the depth at which primary melts originate. Towards this end, this dissertation focuses on plagioclase-hosted melt inclusions from plagioclase ultraphyric basalts (PUBs). Plagioclase is usually considered to be the second phase,...

The Hampton Tuff, High Lava Plains, Oregon : Implications for Westward Migrating Silicic Volcanism

Creator:: Sanville, Henri J.
Abstract:: The Hampton Tuff is a 3.9 ± .02 Ma (2σ) ignimbrite sheet from the High Lava Plains of central Oregon. The majority of known outcrops exist to the north, within ~22 mi (~35 km) of the Frederick Butte Volcanic Center, the proposed source of the tuff. Thickness of the tuff...

Upper-Crustal Magma Evolution at Intermediate Arc Systems : Uranium-Series Zircon Chronochemistry of the Unzen Volcanic Complex, Southwestern Japan

Creator:: Murphy, Bethany S.
Abstract:: Crystal-rich (40-50 vol.%) intermediate lava has been the primary eruptive product of several recent hazardous eruptions: Mt. Pinatubo, Philippines (1991), Soufriere Hills, Montserrat (1995-present), and Unzen, Japan (1990-1995). Despite this association with such devastating eruptions, the formation, timing, and evacuation of such magma is not well understood: do such eruptions...

The geology, geochronology, and geochemistry of the Kaskanak Batholith, and other late Cretaceous to Eocene magmatism at the Pebble porphyry Cu-Au-Mo deposit, SW Alaska

Creator:: Olson, Nansen H.
Abstract:: The Pebble porphyry Cu-Au-Mo deposit in Alaska is one of the world's largest Cu-Au mineral resources. Late Cretaceous magmatic evolution in the Pebble district culminated with the intrusion of the Kaskanak Batholith and associated porphyry copper-gold-molybdenum mineralization. The Kaskanak Batholith is a multiphase granodiorite intrusion with an estimated footprint of...

Rhyolitic magmatism of the High Lava Plains and adjacent Northwest Basin and Range, Oregon : implications for the evolution of continental crust

Creator:: Ford, Mark T.
Abstract:: Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...

Meeting of the magmas : the evolutionary history of the Kalama Eruptive Period, Mount St. Helens, Washington

Creator:: Lieuallen, Athena Erin
Abstract:: Comprehension of eruptive histories is critical in understanding the evolution of magmatic systems at arc volcanoes and may supply evidence to the petrogenesis of intermediate and evolved magmas. Within the 300 ka eruptive history of Mount St. Helens, Washington, the Kalama Eruptive Period, 1479- ~1750 CE was bracketed by interludes...
