Assessing Petal-cutting bees (Megachile sp.) usage of Clarkia amoena (Onagraceae) petals through the lens of iNaturalist and a Garden Experiment

Schöpfer:: Mead, Mallory
Abstract:: Farewell-to-spring (Clarkia amoena) is native to the Pacific Northwest and commonly found in gardens, due to its aesthetic value and purported benefits to pollinators. Oregon and Washington are home to five subspecies of C. amoena, yet commercially available seed is limited to C. amoena ssp. lindleyi and C. amoena cultivars....

Herbage and Sheep Production from Simple, Diverse, and Legume Pastures Established in an Agrivoltaic Production System

Schöpfer:: Andrew, Alyssa C., Higgins, Chad W., Smallman, Mary A., Prado-Tarango, David E., Rosati, Adolfo, Ghajar, Shayan, Graham, Maggie, and Ates, Serkan
Abstract:: Agrivoltaic systems combine solar energy and agriculture, promoting dual land use. Although grazing sheep in these systems is common, research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pastures in an agrivoltaic system...

Evaluation of Bait Crops for the Integrated Management of White Rot (Sclerotium Cepivorum) in Allium Crops

Schöpfer:: Khuong Hoang Hua, Gia, Wilson, Robert, and Dung, Jeremiah
Abstract:: White rot, caused by Sclerotium cepivorum, is a serious disease that causes significant yield losses in Allium production. The pathogen persists in soil as sclerotia, which germinate in response to sulfur compounds in Allium root exudates. This study was aimed at investigating the potential of early-terminated Allium bait crops to...

“Red Light, Yellow Light!”: Evaluating the Anti-Listerial Potential of Bacillus Isolate Metabolites Using a High-Throughput Chromogenic Assay”

Schöpfer:: Johnson, Taylor S.
Abstract:: Listeria monocytogenes contamination continues to pose challenges for the food industry and there is demand for effective methods of food preservation and protection that can also be considered clean label. A promising source of antilisterial compounds may be sourced from bacteria that produce novel byproducts. Ribosomally synthesized and post-translationally modified...

From work-first to learn first : navigating educational choices among TANF recipients through the lens of possible selves and stigma

Schöpfer:: Jones, Terese D.
Abstract:: Individuals who are parents and students on TANF experience challenges accessing and persisting in higher education. This study explored the experiences of TANF recipients who are navigating a return to higher education and the impact of college on how they construct a future self. Two theoretical frameworks were used to...

Injury and Performance-Related Running Biomechanics in Advanced Footwear Technology Compared to Minimalist Footwear

Schöpfer:: Hannigan, J. J., Westley, Luisa, and Jin, Li
Abstract:: Road racing shoes have recently evolved to incorporate maximal midsole cushioning and an embedded carbon fiber plate. Shoes in this category have been labeled ‘Advanced Footwear Technology’ (AFT) and may significantly contribute to improvements in running economy, in part due to biomechanical changes at the foot and ankle. However, little...

Ecological Restoration and Artificial Intelligence: Whose Values Inform a Project?

Schöpfer:: Woodrich, Samuel T. and Pape, Timothy
Abstract:: Significant attention has been given to how artificial intelligence (AI) can be utilized by society and in scientific fields in recent years. This article explores how AI tools utilized in various fields have been and can be applied to ecological restoration projects, their affiliated benefits and drawbacks, and what those...

Factors Affecting Black-footed Ferret Populations within the Great Plains Region of North America: A Case Study

Schöpfer:: Hodges, Rodney J.
Abstract:: The black-footed ferret is a meso-predator within the Great Plains region of North America. Before the 1900s, black-footed ferret populations were self-sustaining in large ecological patches throughout the geographical range of the Great Plains. During the 1900s, various factors such as the systematic extermination of prairie dogs (the primary food...

A Comparative Analysis of Literature Search Results for Chinook Restoration Project Evaluation Between 2012 and 2022 Western Pacific Studies in California, Oregon, and Washington

Schöpfer:: Clark, Erica Jennifer
Abstract:: Pacific salmon are an integral part of ecosystems, industry, culture, and food source. Rapid declines and extirpation in many populations and species have caught the interest of environmentalists, scientists, recreational anglers, commercial fishers, general public, and economists. Billions of dollars have been spent to restore, return, improve, sustain dwindling populations...

Modeling the Visibility Distribution for Respondent-driven Sampling with Application to Population Size Estimation

Schöpfer:: McLaughlin, Katherine R., Johnston, Lisa G., Jakupi, Xhevat, Gexha-Bunjaku, Dafina, Deva, Edona, and Handcock, Mark S.
Abstract:: Respondent-driven sampling (RDS) is used throughout the world to estimate prevalence and population size for hidden populations. Although RDS is an effective method for enrolling people from key populations in studies, it relies on a partially unknown sampling mechanism, and thus each individual’s inclusion probability is unknown. Current estimators for...
