At a time when the biodiversity on Earth is being rapidly lost, new technologies and methods in genomic analysis are fortunately allowing scientists to catalog and explore the diversity that remains more efficiently and precisely. The studies in this dissertation investigate genomic diversity within the milkweed genus, Asclepias, at multiple...
This dataset contains a draft assembly of the common milkweed (Asclepias syriaca) nuclear genome, linkage group information, and gene family counts for Asclepias and related species. The genome assembly is accompanied by annotation of gene models, repeat models, transfer RNAs, and open reading frames, and mapping information of Asclepias transcripts,...
This dataset contains DNA sequence data of Oncorhynchus species, isolated from environmental DNA (eDNA) from Pacific Northwest streams via microfluidic eDNA metabarcoding and high-throughput (Ilummina) sequencing (samples collected from 2017-09-22 to 2017-10-10). It is accompanied by scripts and commands for data analyses including: sequence denoising, calculation of entropy values by...
A series of compounds, 7-8 and 20-25, were tested as competitive inhibitors of 2,5-dihydroxyacetanilide epoxidase I (DHAE I) and DHAE II. A Hammett plot was constructed for each enzyme to determine the effect of electron density on inhibition. DHAE I gave a linear, highly correlated plot (r²=0.91) that signifies the...
Primula sect. Parryi comprises five species endemic to western North America: P. parryi, P. angustifolia, P. rusbyi, P. capillaris, and P. cusickiana with four varieties. This section, derived from a clade with representatives in Asia and Europe, exemplifies a phytogeographic pattern in which a widespread species is accompanied by multiple...
Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...
This study sought to explore the differences between the varied academic advising models in the College of Science at Oregon State University through the feedback of its undergraduate students and advisors. Using parallel surveys of students and their academic advisors, it found that the decentralized and centralized models each had...
The USDA Forest Services' actions have come under greater scrutiny by a public that has become increasingly concerned with the legality of their actions. Often, challenges involve the quality of science used in the decision-making. Congress has mandated that the agency use the "best available science" in its decision making...
Despite knowledge that concerted evolution of high-copy loci is often imperfect,
studies that investigate the extent of intragenomic polymorphisms and comparisons
across a large number of species are rarely made. We present a bioinformatic pipeline
for characterizing polymorphisms within an individual among copies of a high-copy
locus. Results are presented...
