Systematic review of residual toxicity studies of pesticides to bees and comparison to language on pesticide labels using data from residual toxicity studies and USEPA published values

Creator:: Swanson, Leah
Abstract:: BACKGROUND. Residues of pesticides on crops can result in mortality to foraging bees. The likelihood of mortality can be mitigated by applying pesticides in the evening so that their residues dissipate by the following morning when bees resume foraging. The dissipation rates of different pesticides, or their residual toxicity, is...

Physiological effects of forb and legume pastures on lactating dairy cows as indicated by blood parameters

Creator:: Marr, Kaylee M.
Abstract:: Use of secondary metabolites in legumes and herbs as forage for dairy cattle is tested through analysis of blood parameters including beta-hydroxybutyrate (BHBA), cholesterol, urea, creatinine, haptoglobin, bilirubin, thiol groups and advanced oxidation protein products (AOPP). The pasture treatments were grass-based (‘Perun’ festulolium (X Festulolium braunii), ‘Rustler’ tall fescue (Festuca...

Effects of selenium supplementation during different trimesters of pregnancy on non-specific humoral immunity of pregnant beef cows and persistence of antibodies in their newborn calves

Creator:: Thompson-Hernandez, Ian
Abstract:: Immunosuppression during the periparturient period leads to increased susceptibility to infectious diseases in beef cows. Newborn calves rely on passive transfer of antibodies from their mothers at birth for protection against diseases in the first two months of age. It is unknown if supranutritional Se supplementation of cows during pregnancy...

Evaluating the response of bees to visual attractants in resource-poor environments

Creator:: Parvin, Lucas
Abstract:: Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...

Expression Properties of Two Promoters During Callus and Shoot Development in Transgenic Poplar

Creator:: Brousseau, Anna G.
Abstract:: The Arabidopsis thaliana developmental promoters of WUSCHEL (WUS) and COLD SHOCK DOMAIN PROTEIN 3 (CSP3) were tested for their suitability as potential control elements for the Cre-Lox recombination system in poplar cells. To remove the integrated transgene after CRISPR machinery has modified the genome, timely control of Cre is required....

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...

Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:: Bell, Nicole C. S.
Abstract:: Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Effects of Selenium Supplementation During Different Trimesters of Pregnancy on Total and Vibrio coralliilyticus Specific IgM Antibody Concentrations in Beef Cows at Parturition

Creator:: Zurita Cruz, Cindy
Abstract:: Background: The immune response to microbial infections is compromised in beef cattle at parturition. Innate and adaptive immunoglobulin M (IgM) serve as initial antibodies during microbial infection before the generation of adaptive immunoglobulin G (IgG). Selenium (Se) is an essential micronutrient required by all mammals, which can improve immune responses...

Choose native plants that will help Oregon bee populations thrive in changing urban environments

Creator:: Asselin, Kelley
Abstract:: Bees play a crucial role in pollinating crops, supporting biodiversity, and maintaining ecosystem health. Despite their importance, the decline in bee populations has become a global concern due to various factors including habitat loss, urbanization, and climate change. The purpose of this thesis is to write an article that highlights...

Perceptions of climate change in herbalism and harvesting

Creator:: Noall, Amelia
Abstract:: This study looked at the impacts of climate change on medicinal plants, and how these impacts are viewed and understood in the herbalism community. Two literature reviews were conducted, to look at each of these two ideas: the first was a review of peer-reviewed literature describing research on climate change...
