This capstone project is presented for completion of Oregon State University’s (OSU) Master of Natural Resources Program. This project is an expansion of the author’s research completed as part of the Water Conflict Management and Transformation Certificate and as part of the overall Master of Natural Resources Program.

There are more than 6,900 known living languages in the world, half of which could be extinct within one hundred years. Approximately 150 indigenous American languages are still spoken in the United States; however, it is estimated that by the year 2050 only twenty of them will remain.

Though previous genetic research studies performed on Caenorhabditis elegans
found that high levels of endogenous oxidative stress resulted in decreased health, and
that mitochondrial DNA deletions accumulated with age in these organisms, no studies
have been conducted to link these two separate findings. This study correlated these
separate results by...
The fishing industry in the Pacific Northwest is a dynamic and highly competitive industry that must constantly respond to rapidly changing resource, regulatory and market forces. These forces have already had a significant impact on our fisheries and will continue to do so as we learn more about the biology...
We give a new approach to coding sequence (CDS) density
estimation in genomic analysis based on the topological pressure, which
we develop from a well known concept in ergodic theory. Topological
pressure measures the ‘weighted information content’ of a finite word,
and incorporates 64 parameters which can be interpreted as...
Understanding the molecular mechanisms of ultraviolet (UV) induced melanoma formation is becoming crucial with more
reported cases each year. Expression of type II nuclear receptor Retinoid-X-Receptor α (RXRα) is lost during melanoma
progression in humans. Here, we observed that in mice with melanocyte-specific ablation of RXRα and RXRβ, melanocytes
attract...

We investigate electron transport properties in large-area, single-layer graphene embedded in dielectric media, using free-space terahertz (THz) imaging and time-domain spectroscopy. Sandwiched between a thin polymethyl methacrylate (PMMA) layer and a Si substrate, graphene layers of different growth recipes exhibit distinctive spatial inhomogeneity of sheet conductivity. The non-contacting, non-destructive THz...
Photosynthetic diatoms and marine bacteria contribute about one third of the net primary production in marine environments. Understanding the interactions between these two organisms is potentially important to the over all flow of carbon in the marine ecosystem.
Appendicularians are ubiquitous marine grazers that use tangential filtration to collect micron and submicron prey. The food-concentrating filter (FCF) is the primary determinant of appendicularian prey selectivity, but the precise means by which it concentrates and conveys particles to the pharyngeal filter remain poorly understood. We used high-speed videography to...
Species distribution models (SDMs) are increasingly applied in conservation management
to predict suitable habitat for poorly known populations. High predictive performance of
SDMs is evident in validations performed within the model calibration area (interpolation),
but few studies have assessed SDM transferability to novel areas (extrapolation), particularly
across large spatial scales...

Oregon has done remarkably well in preserving forests, farms, and rangeland from development. Ninety-seven percent of all non-Federal land in Oregon that was in resource land uses in 1974 remained in those uses in 2014. Ninety-nine percent of all non-Federal land in Oregon that was in resource land uses in...
The Oregon 4-H Carcass of Merit Program offers recognition to Oregon State University Extension 4-H members who breed and/or buy, feed, and raise animals whose carcasses meet the “ideal” for red meat: lean, early maturing, high yielding, and containing minimal external fat. This
publication was prepared for 4-H leaders and...
We investigated the species identity and local use of cetaceans on the Gilbert
Islands, Republic of Kiribati. Working with the Kiribati Ministry of Environment,
Lands and Agricultural Development and Fisheries Division, we visited
the islands of Tarawa, Tabiteuea (North), Butaritari and Onotoa from June to
July 2009, and collected 24...

We investigate the response of multi-layer epitaxial graphene and chemical vapor deposition (CVD)-grown single-layer graphene to strong terahertz (THz) fields. Contrary to theoretical predictions of strong nonlinear response, the transmitted fields exhibit no harmonic generation, indicating that the nonlinear response is limited by fast electron thermalization due to carrier-carrier scattering....
We present genetic and morphological evidence supporting the recognition of a previously synonymized species of Mesoplodon beaked whale in the tropical Indo-Pacific, Mesoplodon hotaula. Although the new species is closely-related to the rare ginkgo-toothed beaked whale M. ginkgodens, we show that these two lineages can be differentiated by maternally (mitochondrial...
