Urban landscape soils are often compacted by construction activities, thereby restricting plant establishment. Common approaches to improve plant establishment on compacted soils are to till soil before plant installation, to apply compost, or to choose plants that can tolerate drought. This research was undertaken to evaluate the relative importance of...
A review of research conducted at OSU to determine compost value as a mulch or soil amendment for blueberry produced under conventional, transitional, or organic production systems.
The literal distance inherent in online education can be an important difference between it and traditional classroom settings, such that proximate, on-site learning is thought to be where experiential, transformative education happens (Cohen, 2013). Yet it is possible that some of the most compelling, effective aspects of traditional, proximate education...
Online teaching and learning has become an increasingly important aspect of the educational mission of universities. In person, teachers have time-tested tools for assessing student ability, including a wealth of verbal and nonverbal communication. The online format provides a wealth of data, and promises—but may not yet deliver—useful tools for...
As an Oregon State Ecampus Research Fellow, I designed and initiated a research study that aimed to: 1) investigate tools and techniques for engaged, experiential online learning with undergraduate philosophy students and 2) propose disciplinespecific criteria for evaluating the impact of these pedagogical interventions. The study was designed to answer...
Everyone involved in online education talks about community – what is it, how is it created, do students really want it? Most researchers now agree that online education is enhanced through a greater sense of community within the online classroom; however, the factors that make for a substantive and quality...
Prior research has suggested that homework activities that encourage learners to think more conceptually about to-be-learned material can have positive benefits on overall content learning. Can such activities be implemented successfully in online coursework, and does it produce the anticipated benefit? In two sections of an online Psychology course, participants...
Massive Open Online Courses (MOOCs) have generated considerable excitement and considerable skepticism since their recent inception (e.g., Kim, 2014; Perna et al., 2014). By fall 2015, approximately 35 million people had participated in 4200 courses offered by over 550 institutions (Shah, 2015). In addition to MOOCs’ potential for expanding access...
This pocket guide highlights fire-resistant plants that thrive in Willamette Valley growing conditions. It recommends groundcovers, perennials, shrubs, woody vines, and trees. There are too many annual plants available to list them all. In general, annuals are considered fire-resistant if they are kept well irrigated.
The data retrieved from gt;momic sequencing techniques provides the raw information required to infer the basis of mutations and their resulting phenotypes, wherein plant ontologies can be utilized in annotating said phenotypes using a common, shared vocabulary. By relating mutant genes of similar phenotypes both within and between plant species,...
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with CO₂ precision plot sprayers. Unless otherwise indicated, preplant...
TiO₂ typically crystallizes into three polymorphs: brookite, rutile, and anatase. The phase selection problem in TiO₂ is the lack of understanding what conditions cause amorphous TiO₂ to crystallize into one of its three polymorphs during an annealing process. It has been recently shown that phase selection in TiO₂ is highly...

The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....
This report, required by state law under HB3543, provides a comprehensive assessment of the state of science of climate change as it pertains to Oregon, covering the physical, biological, and social dimensions. The first chapter summarizes the current state of knowledge of physical changes in climate and hydrology, focusing on...
Climate Change in the Northwest: Implications for Our Landscapes, Waters, and Communities is a report aimed at assessing the state of knowledge about key climate impacts and consequences to various sectors and communities in the Northwest United States. This report draws on two recent state climate assessments in Washington in...
This Guidebook follows a holistic approach to adaptation planning called community-driven climate resilience planning. Community-driven climate resilience planning is “the process by which residents of vulnerable and impacted communities define for themselves the complex climate challenges they face, and the climate solutions most relevant to their unique assets and threats.”...
The main objective of this project was to compare on-farm measurement techniques for estimating N-contributions from cover crops using 1) separated species lab tests (a standard experimental method), 2) bulked species lab tests, 3) fresh weight, 4) dry weight and 5) canopy height and density. We also recorded relative weed...

Aquaculture is a continuously growing industry, but rising problems are disease and antibiotic resistance. A common disease-causing pathogen in oyster aquaculture is Vibrio coralliilyticus (Vcor). Vcor infection of oyster larvae causes near 100% mortality within 48 hours, which is devastating to oyster hatcheries. One potential method of controlling Vcor outbreaks...
