The aim of this research was to provide forest managers and researchers with a better understanding of individual tree defenses and tree responses to disturbances, within a Collaborative Forest Landscape Restoration Program area. Forest restoration often aims to increase stand-level resistance to uncharacteristic changes, and stand-level resistance begins with tree-level...
Central Oregon is the primary U.S. hybrid carrot seed production area, supplying seed to the domestic fresh market carrot industry. Approximately 85 percent of the hybrid carrot seed planted in the United States is grown
in Jefferson and adjoining counties. The Madras and Culver areas support most of the carrot...
Drone strikes have become a defining strategy in the US War on Terror. Since the first combat drone strike in 2001, the executive branch has intentionally increased the deployment of drones for counterterrorism operations throughout the Middle East and North Africa. This thesis explores the moral and legal justifications for...
Several types of caneberries are produced commercially in Oregon, including summer-bearing and primo cane fruiting red raspberries, black raspberries (blackcaps), and blackberries. This publication addresses nutrient assessment
and application for caneberries produced in western Oregon.
In this area, caneberries typically are planted on Aloha, Jory, Newburg, Willamette, Woodburn, or Saum...
Silage corn makes excellent feed for dairy cattle because of its high dry-matter yield, energy content, and palatability, especially when mixed with other feed. Also, it does not accumulate potassium as do many
cool-season grass species. Nitrogen (N) is the most yield-limiting nutrient for silage corn production. Most dairies in...
Tall fescue is grown for turf or forage seed on a broad range of soils in western Oregon. Typical seed yield is 1,200 to 2,000 lb/acre. Higher yields do not require additional nutrients beyond amounts recommended in this guide. These recommendations, especially for nitrogen, are adequate for production of more...
Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...

Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...
Null networks are a type of random graph that is favored for the analysis of a wide variety of real-world networks, including gene-regulatory networks, food webs, and species co-occurrence matrices. As a hypothesis-generating tool, null networks are invaluable because they can reveal network motifs and unusual large-scale properties of networks...
Specialized or secondary metabolism is a collection of pathways and small molecules that, while beneficial to an organism, are not strictly necessary for survival. Plants use secondary metabolites to, among other things, attract pollinators, defend against biotic and abiotic stressors, and form symbioses. Natural products from plants have seen an...
Gene regulation is a complex mechanism that controls the spatial and temporal expression of genes in a living cell. My dissertation studies focus on two problems. First, tissue-specific gene expression prediction from DNA sequence and chromatin state, and second, the accurate discovery of small over-represented regulatory circuits in gene regulatory...
Recommendations in this nutrient management guide apply to spring or winter canola (Brassica napus or Brassica rapa) grown under irrigated or dryland management in rotation with a variety of crops. Recommendations for nitrogen, phosphorus, sulfur, potassium, zinc, boron, and lime are covered in this guide.
Observations of annual growth and size and color of leaves and fruit are helpful in determining fertilizer needs. In addition, leaf analysis
indicates which elements are present in adequate, deficient, or excessive amounts. Soil analysis is useful in predicting the need for lime applications. Suspect a nutrient deficiency if poor...
A method for measuring the (dis)charging dynamics of organic semiconductors with single-electron resolution in multiple environments is developed using optical tweezers. A 1μm silica bead was coated with either a pristine organic semiconductor or an electron donor-acceptor blend, trapped using optical tweezers, and driven with an oscillating electrical driving force....
To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I took up the task of identifying the algal species on 42 of the most heavily fouled debris items that landed on the...

Pasture legumes that persist under challenging agro-ecological conditions are crucial to ensure high lamb growth rates in dryland pastures. Pasture and lamb production from white clover (TF-Whc), birdsfoot trefoil (TF-Bft), balansa clover (TF-Bc) and subterranean clover (TF-Sc) planted with tall fescue either as binary mixtures or as a diverse combination...
Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...
Gender has been the subject of study in engineering education and science social research for decades. However, little attention has been given to transgender and gender nonconforming (TGNC) experiences or perspectives. The role of cisgender or gender conforming status has not been investigated nor considered in prevailing frameworks of gender...
The Ni-les’tun tidal wetland restoration project in the Coquille River Estuary in southern Oregon is one of the largest and most well-studied tidal restoration projects on the Pacific Northwest coast. However, ecological data on restoration effectiveness and ecosystem change following restoration are relatively rare for projects more than a few...
