Tracking the Range Expansion of a Native Bee, the Squash Bee, Eucera (Peponapis) pruinosa; (Hymenoptera: Apidae) in Oregon using Community Science

Creator:: Jones, Miranda L.
Abstract:: The foraging distance of bees has been intensely studied. In contrast, little is known about the factors that determine bee dispersal distance, especially on large spatial scales. Eucera (Peponapis) pruinosa is a wild ground nesting bee that exclusively collects pollen from squash in the genus Cucurbita. Although the bee occurs...

Quantifying the Potential of Native Plants for Improving Pollination and Biological Control in Agroecosystems

Creator:: Winfield, Tammy L.
Abstract:: Agricultural areas can be inhospitable to the attraction and maintenance of beneficial insects like natural enemies and pollinators and this can result in a decrease in the ecosystem services of pollination and pest control that these insects supply. If habitat can be created and maintained on-farm, an increase in the...

Invest in Vegetables: A Cost and Benefit Analysis of Container Grown Roma Tomatoes (Solanum lycopersicum cv. ‘Roma’) and Italian Basil (Ocimum basilicum cv. ‘Italian’)

Creator:: Spofford, Tyler S.
Abstract:: The COVID-19 pandemic highlighted disparities in land access and food security. Research has shown that access to gardening reduces financial burdens on low-income households. Compared to homeowners, individuals and families in rental housing face added barriers to vegetable gardening and growing food. These barriers include rental housing regulations and the...

Exploring the Growth Habits of Sweetpotatoes (Ipomoea batatas) in the Willamette Valley of Western Oregon

Creator:: Epps, Charlotte
Abstract:: Sweetpotatoes are a highly nutritious staple crop, playing an important role in global nutritional security. Although the majority of research in the United States (U.S.) focuses on the cultivation of the storage roots, both the leaves and roots are edible. Sweetpotatoes are indigenous to the Andes Region of South America;...

Impacts of Range Management Decisions on Native Pollinators: Innovative Grazing Practices and Riparian Restoration

Creator:: Mitchell, Scott R.
Abstract:: Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....

Fingerprinting, reproductive behavior and pollinator dynamics of Buddleja davidii and interspecific hybrids

Creator:: Still, Cara M.
Abstract:: Buddleja davidii (butterfly bush) is a highly adaptable landscape plant known for pollinator attraction. Unfortunately, it is also regarded as an invasive plant in highly disturbed environments across the globe. It is an invasive species in Oregon, officially classified as a class B noxious weed in 2004. Currently the state...

Development and Application of Tools for Genetic Analysis of Clonal Populations

Creator:: Kamvar, Zhian N.
Abstract:: Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...

Governing By Nature

Creator:: Rhodes, Mericos H.
Abstract:: The choice of what to eat is political, and food systems shape and are shaped by political and economic power. During the last several hundred years, agricultural and food power has been consolidated to an unprecedented degree, and this consolidation continues today. This paper will describe this process as “Governing...

Olives in Oregon: Grower Survey, On-Farm Propagation, and Orchard Establishment in a Non-Traditional Growing Region

Creator:: Barker, Tessa A.
Abstract:: Olive production potential in Oregon was researched in a multi-disciplinary approach, including a grower survey, a propagation greenhouse study, and a field study, from 2018 through 2020. The Oregon Olive Grower Survey was designed to collect information relating to orchard establishment and management practices, knowledge and understanding of these practices,...

Alternative Controls for Stephanitis pyrioides in the Pacific Northwest.

Creator:: Graham, Katerina V.
Abstract:: The azalea lace bug (Stephanitis pyrioides Scott) is a global pest of rhododendrons and azaleas (Rhododendron spp.). It is originally from Asia, has been established in the eastern U.S. for the past century, and was recently detected in the Pacific Northwest in 2008-2009. Stephanitis pyrioides feeds on the underside of...
