Cryopreservation of adherent cells may be advantageous for cell types that are difficult to
preserve in suspension or when it is necessary to preserve characteristics of the adherent cultured cells. Vitrification is a promising procedure for the preservation of adherent cells that prevents ice crystal formation and the resulting dissociation...
Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed in November, 2011...
Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes...
Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...
Herein, we posit a link between the ecological extinction of wolves in the American West
and the expansion in distribution, increased abundance, and inflated ecological influence
of coyotes. We investigate the hypothesis that the release of this mesopredator from wolf
suppression across much of the American West is affecting, via...
Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...
Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...
This publication gives an overview of processing cherry production in Oregon and describes cherry cultivars used for brining, freezing, and canning. It also provides information on diverting fresh-market cherries to the processing industry and developing strategies for profitability.
More than 30 members of the diverse amphidinolide family of biologically active macrolides have been isolated over last three decades. From this family, amphidinolides C and F stand among the most complex and densely functionalized affiliates. Recently, we have accomplished the first total synthesis of amphidinolide F. The all-carbon framework...
Climate-induced changes may be more substantial within the marine environment, where following ecological change is logistically difficult, and typically expensive. As marine animals tend to produce stereotyped, long-range signals, they are ideal for repeatable surveying. In this study we illustrate the potential for calling rates to be used as a...
This is the PowerPoint (PDF) file for a 60-minute workshop for graduate students covering data management best practices. Topics covered include general recommendations for data management in terms of planning, data description (metadata), file formats and naming conventions, ethics and consent, copyright, and sharing and archiving of data. The workshop...
Regularly producing sustainable yields of high-quality cherries is possible only where site and other conditions are near optimal. This publication summarizes factors to consider when establishing a cherry orchard including orchard economics, site selection and optimization, plant material, orchard design, fertilization and irrigation, and labor. Also lists additional resources.
This publication describes how to calibrate waste-handling equipment and calculate nutrient application rates. It covers calibration of typical equipment found on dairies, such as stationary guns, traveling guns, liquid wagons, and solids spreaders. It uses nitrogen in the calibration examples, but the same techniques can be used with phosphorus.
Identifying effective strategies for increasing access to quality care for children from low-income families has important implications for society. This study examined the effectiveness of expanding child care assistance for low-income families (capping expenses at 10% of income and raising eligibility to 200% of the federal poverty line) to purchase...
This publication reviews the growth stages of grapes. For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects, weeds, and disease, their rates, and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control...
We develop a classical density functional for water which combines the White Bear fundamental-measure theory (FMT) functional for the hard sphere fluid with attractive interactions based on the statistical associating fluid theory variable range (SAFT-VR). This functional reproduces the properties of water at both long and short length scales over...
Our understanding of the effects of land use regulations and other aspects of urban form has been hindered by limited aggregate data and gradual temporal changes in policies. More widely available GIS data on land use and land economics presents opportunities to overcome these obstacles. This study was undertaken to...
from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...
There are many different types of automatic data collection technologies that have been used in transportation system applications such as pneumatic tubes, radar, video cameras, inductive loops detectors, wireless toll tags, and global positioning systems (GPS). Nevertheless, there are still multiple examples of important and helpful transportation system data that...
Librarians at Oregon State University undertook a teaching competency project to lay the
foundation for practices that improve teaching by adapting the core teaching proficiencies in the
ACRL Standards for Proficiencies for Instruction Librarians and Coordinators. This article
describes one model for locally adapting those proficiencies, the Oregon State University...
