Presented at the annual meeting of the Northwest Archivists, this talk discusses the workflows deployed by the Oregon State University Libraries Special Collections and Archives Research Center (SCARC) to provide access to digitized moving images materials. The presentation also describes the ways in which SCARC intends to use new features...
Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....
Balancing selection is one of the mechanisms which has been proposed to explain the maintenance of genetic diversity in species across generations. For species with large populations and complex life histories, however, heterogeneous selection pressures may create a scenario in which the net effects of selection are balanced across developmental...
Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers are obtained from AVIRIS imaging spectroscopy and linear spectral mixture models are used to visualize spatial patterns...
Restoration to achieve Stage 0 is a valley-scale, process-based (hydrologic, geologic and biological) approach that aims to reestablish stream depositional environments to maximize longitudinal, lateral, and vertical connectivity at base flows and facilitate development of dynamic, self-formed and self-sustaining wetland-stream complexes. The term Stage 0 originally described complex multi-channel conditions...
The past three years have underscored the importance of quality digital library resources and services. Oregon Digital (https://oregondigital.org), the shared digital collections repository for the University of Oregon and Oregon State University, launched a new platform in February 2023. This poster will showcase the development and migration work that the...
Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...
Coastal communities face heightened risk to coastal flooding and erosion hazards due to sea-level rise, changing storminess patterns, and evolving human development pressures. Incorporating uncertainty associated with both climate change and the range of possible adaptation measures is essential for projecting the evolving exposure to coastal flooding and erosion, as...
The objectification of women is a scourge of society, related to a host of negative mental and physical health implications for women. Objectification is largely influenced by the types of clothing worn. How much is objectification modified by contextual features (e.g., the situations the clothes are worn in)? In two...
Background:
The Amazon River runs nearly 6500 km across the South American continent before emptying into the western tropical North Atlantic Ocean. In terms of both volume and watershed area, it is the world’s largest riverine system, affecting elemental cycling on a global scale.
Results:
A quantitative inventory of genes...
Spatial climate datasets of 1981–2010 long-term mean monthly average dew point and minimum and maximum vapor pressure deficit were developed for the conterminous United States at 30-arcsec (~800m) resolution. Interpolation of long-term averages (twelve monthly values per variable) was performed using PRISM (Parameter-elevation Relationships on Independent Slopes Model). Surface stations...
In a recent effort to strengthen active preservation strategies, Oregon State University Libraries committed to conducting a multi-part annual preservation assessment for our institutional repository, focusing on the sustainability of file formats. This spring we conducted the first assessment, gathered a lot of data, and uncovered a few holes in...
The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....
Recent warnings from scientists suggest there is limited time to enact policies to avert wide‐ranging ecological and social damage from climate change. In the United States, discussions about comprehensive national policies to avert climate change have begun, with “Green New Deal” proposals and climate plans put forth by members of...
Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory...
The worksheet is designed to show a municipal biosolids manager how many acres are needed for land application of biosolids at an agronomic rate, based on crop nitrogen (N) requirements.
The worksheet is based on a peer-reviewed Extension publication: PNW 511, Worksheet for Calculating Biosolids Application Rates in Agriculture authored...
Oregon State University (OSU) is a leader in delivering online education, including several natural science field-based programs and dozens of courses with field-based aspects. Natural science field-based learning teaches students to observe, analyze, and outline management actions for broad and complex land areas and natural resources issues. To effectively do...
Trust is a key variable for successful natural resource management and is commonly the focus of conceptual and methodological development. Distrust, on the other hand, is frequently cited as an obstacle to management, but appears to be rarely defined, conceptually underdeveloped, and inconsistently examined. This systematic review protocol (OSF preregistration...
