Multiple stressors are currently threatening honey bee health, including pests and pathogens. Among honey bee pathogens, Nosema ceranae is a microsporidian found parasitizing the western honey bee (Apis mellifera) relatively recently. Honey bee colonies are fed pollen or protein substitute during pollen dearth to boost colony growth and immunity against...
The way that an individual defines and understands the term “disability” has the potential to affect how they view and interact with people with disabilities.

Winter squash (Cucurbita maxima) grown in Oregon’s Willamette Valley for edible seed, frozen foods, and fresh markets is susceptible to an undiagnosed soilborne disease. Diseased squash fields exhibit symptoms of stunting, root and crown rot, vascular discoloration, and late-season wilt, which in extreme cases can lead to total crop failure....
The severity of carbonate chemistry changes from ocean acidification is predicted to increase greatly in the coming decades, with serious consequences for marine species- especially those reliant on calcium carbonate for structure and function (Fabry et al. 2008). The Northern California Current Ecosystem off the coast of US West Coast...
1,4-dioxane, a probable human carcinogen at low (< 1ppb) concentrations, has emerged as a groundwater contaminant due to its historical use as a stabilizer for the chlorinated solvent 1,1,1-trichloroethane. Aerobic cometabolism, the use of a primary substrate to induce the production of microbial enzymes that fortuitously degrade other compounds, is...
This thesis focuses on Latin Crusader unity, or the lack thereof, during the First Crusade. Letters written during the First Crusade show that crusaders used rhetoric of unity to affirm superiority over their enemy, to dissolve differences between one another, and to justify the warfare. The reality of the First...
This thesis is a report of a phenomenological-informed study of public university student spiritual development. The research was based primarily upon semi-structured personal interviews and a focus group with undergraduate students at a large, public research institution on the west coast. Since the introduction of scientific objectivity into the academy...
The effects of enriching the rearing environment of laying hens on their learning ability and behavior were investigated. Day old ISA brown layer chicks were group housed in open floor pens that were either enriched or unenriched. The enriched rooms contained visual stimuli in the form of hanging decorations, auditory...
Red tides are algal blooms that have caused significant ecological and
economic damage in Florida. Different nations and regions have addressed
harmful algal blooms such as red tides a variety of ways including distinct
strategies designed to prevent, control and or mitigate the negative effects
of a bloom. While a...
