Investigating the effects of harvest time and light exposure on cannabinoid potency in industrial hemp (Cannabis sativa) using UPLC-diode array detection

Creator:: Saindon, Ashley L.
Abstract:: Five varieties of industrial hemp (Cannabis sativa) were grown in the field in Imperial Valley, CA, USA in order to determine whether light conditions or harvest times influence cannabinoid content. A total of 16 cannabinoids were investigated in this study: Delta-9-tetrahydrocannibinol (THC-d9), Delta-9-tetrahydrocannibinolic acid (THC-a), Cannabidiol (CBD), Cannabidiolic acid (CBD-a),...

Article Deposit Services in Support of Federal Agency Public Access Requirements

Creator:: Boock, Michael, Zhang, Hui, and Clark, Erin
Abstract:: INTRODUCTION: Academic libraries have experimented with a variety of services to encourage article deposit to institutional repositories, with varying degrees of success. Universities now face the challenge of meeting federal agency public access requirements. Following the White House Office of Science Technology and Policy public access directive in 2013, Oregon...

Advancements in Phytoremediation, Dosimetry, and Environmental Radiological Protection: Integrating Endemic Plants, Anatomically Accurate Phantoms, and Real-world Data for Improved Assessments

Creator:: Hargraves, Joshua T.
Abstract:: The environmental impact of the nuclear industry has prompted the need for innovative remediation strategies and accurate radiological assessments. This paper synthesizes three studies that collectively explore the potential of endemic plant species for phytoremediation, the development of anatomically accurate phantoms for precise dosimetry calculations, and the critical evaluation of...

Into the Garden: Environmental Education and Resources for K-5

Creator:: Smith, Amira R.
Abstract:: This thesis aims to address barriers that K-5 educators face when implementing environmental education in classrooms. An in-depth study of the history of environmental education in the United States identifies primary barriers and issues. Focusing specifically on garden education programs, six lesson plans for K-5 were created to address the...

Coastal protection and conservation on sandy beaches and dunes : Context-dependent tradeoffs in ecosystem service supply

Creator:: Ruggiero, Peter, Seabloom, Eric W., Hacker, Sally D., Biel, Reuben G., and Cohn, Nicholas
Abstract:: Managing multiple ecosystem services (ESs) across landscapes presents a central challenge for ecosystem-based management, because services often exhibit spatiotemporal variation and weak associations with co-occurring ESs. Further focus on the mechanistic relationships among ESs and their underlying biophysical processes provides greater insight into the causes of variation and covariation among...

Land Use Impacts on Water Quality in Oak Creek Watershed

Creator:: Johnson, Keira R.
Abstract:: Understanding the relationships between land use, water quality, and groundwater is crucial for ecological, economic, and water management decisions. This study aims to provide a comprehensive analysis of the land use activities and hydrologic processes influencing the water quality of Oak Creek watershed. Objectives of this study were: 1) to...

Discovery of a dune-building hybrid beachgrass (Ammophila arenaria × A. breviligulata) in the U.S. Pacific Northwest

Creator:: Mostow, Rebecca S., Barreto, Felipe, Biel, Reuben, Meyer, Eli, and Hacker, Sally D.
Abstract:: The production of novel hybrid zones is an ecologically important consequence of globally increasing rates of species introductions and invasions. Interspecific hybridization can facilitate gene flow between parent species or produce novel taxa that may alter invasion dynamics or ecosystem services. The coastal sand dunes of the U.S. Pacific Northwest...

Mapping Atmospheric Moisture Climatologies across the Conterminous United States

Creator:: Daly, Christopher, Smith, Joseph I., and Olson, Keith V.
Abstract:: 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...

Correlation Between Fine Particulate Matter and Traffic Type and Density in Curitiba, Brazil

Creator:: Fantoni, Costanza
Abstract:: Traffic exhaust is an important source of air pollution. This exposure assessment study examined traffic related air pollution in Curitiba, Brazil, and is particularly relevant due to 75% of the population using diesel public transportation. Traffic density was tabulated, and vehicle-type was distinguished based on their fuel type (diesel or...

Environmental Relationships in Forests of Early 20th Century Coos County, Oregon, Based on Timber Cruise Data

Creator:: Zobel, Donald B.
Abstract:: Timber cruise data can provide useful information not available elsewhere. Measurements of timber volume (timber cruises) from the early 20th century for Coos County, Oregon, were used to assess the degree to which tree species distribution and timber volume varied with edaphic and climatic factors. The study area has diverse...
