Morphology, Sediment Microbial Analysis, and Species Distribution Modeling of a New Offshore Population of Ghost Shrimp (Neotrypaea sp.)

Creator:: Hardisty, Sarah
Abstract:: In 2019, a multi-cohort population of the typically estuarine burrowing shrimp Neotrypaea sp., was discovered approximately 7 miles offshore of Newport, Oregon. Morphological analysis of the offshore population, microbial sediment sequencing, and species distribution modeling was conducted with this new offshore population. In order to identify Neotrypaea sp. to the...

Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

Creator:: Kopper, Neil H.
Abstract:: Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Effects of earthflows on stream channel and valley floor morphology western Cascade Range, Oregon

Creator:: Vest, Sarah B.
Abstract:: Slow moving earthflows (0.1 15 m/yr.) may constrict valley floors and directly impinge on stream channels. Earthflows that move laterally into channels deliver organic and inorganic material to the stream from the earthflow toe. If the amount and particle size of this material is too large to be removed by...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

Fluorescence Spectrometry to Quantify Percent Wood Failure in Adhesive Bonds

Creator:: Rueppel, Talbot B.
Abstract:: Structural engineered wood manufacturers need a quantitative measurement technique to determine the ratio of wood to adhesive failure in their shear specimens. Visual estimation of percent wood failure has long stood as an extremely subjective quality control approach according to ASTM D5266 – Standard Practice for Estimating the Percentage of...

Reef Microbiomes of Mo'orea, French Polynesia, a Socio-Ecological Island System

Creator:: McConnell, Kaitlin M.
Abstract:: At a time of rapid global change, a socio-ecological system (SES) approach can provide a framework through which to quantify and communicate the risks and uncertainties of coupled human-natural systems. Islands, and tropical coral reef islands in particular, can be excellent models for SES research since they may be considered...

Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

Creator:: Lattier, Kim Shearer
Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....
