The Occurrence of Acarapis dorsalis, Acarapis externus and Acarapis woodi Mites in honey bee populations surrounding Poitiers, France

Creator:: Jillson, Katherine M.
Abstract:: Acarapis mites have been present in the United States since 1984 and are presently considered a threat to honey bee populations in North America. They have been present in Europe since 1921 where infestation rates have now dwindled to a level that is not considered dangerous. Consequently, accurate information on...

Epidemiological implications of sporozoite aggregation in malaria vectors

Creator:: Li, Xiaohong, 1963-
Abstract:: This study describes and quantifies some microprocesses of malaria transmission including blood vessel location by Anopheles stephensi and sporozoites delivery of An. stephensi infected by Plasmodium berghei. The study models the effects of malaria parasite-induced changes in probing behavior and mosquito mortality on disease transmisson. Finally, host, vector, and parasitological...

Behavioral adaptations and the minimization of reproductive costs in the male red-sided garter snake, Thamnophis sirtalis parietalis.

Creator:: O'Donnell, Ryan P.
Abstract:: The benefits of reproduction are clear, but there are also costs. Much is known about the costs of reproduction in females, but only recently have male costs been investigated in any depth. These costs of reproduction may be minimized by appropriately modifying behavior, but there has been little research on...

Antioxidant enzyme response in rainbow trout (Oncorhynchus mykiss) after subchronic exposure to an environmentally-relevant polycyclic aromatic hydrocarbon mixture

Creator:: Norby, Tyler S.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are significant pollutants in aquatic environments. Many are carcinogenic and lead to DNA fragmentation and adduct formation in marine and freshwater organisms. Previous research demonstrates that rainbow trout (Oncorhynchus mykiss) compensate to long-term PAH dietary exposures and reduce the DNA damage. The aim of this study...

3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

Creator:: Scoggins, Luke A.
Abstract:: A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

The Clerk’s Tale : literal monstrosities and allegorical problems

Creator:: Brock, Christopher J.
Abstract:: My thesis, entitled “The Clerk’s Tale: Literal Monstrosities and Allegorical Problems,” argues that Chaucer’s Clerk is engaging both sides of a binary system. The Clerk has situated himself in a precarious position between two major schools of thought in the medieval culture, Franciscan and Dominican; the former promotes the will...

Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...

Development of a synoptic map-pattern climatology to supplement current weather forecasting methods

Creator:: Frey, Melissa D. (Melissa Dawn)
Abstract:: Many meteorologists rely heavily on their experience of past weather events to supplement their forecasting tools, such as using past experience to help decide between conflicting numerical weather prediction models. Experiential knowledge is an important piece of forecasting, however it is highly subjective and variable from one forecaster to another....

An integrated study of mechanical forest fuel reduction: quantifying multiple factors at the stand level

Creator:: Bolding, Michael Chad, 1977-
Abstract:: Recent catastrophic wildfires have forced the forest management community to develop new strategies for reducing forest fuels. Tightly spaced understory trees often create a fire ladder allowing surface fires to encroach into the crowns of overstory trees. This situation can lead to intensive, catastrophic, stand-replacement forest fires. Mechanical removal or...

Studies toward the total synthesis of alkaloids : nagelamide A and D, agelastatin D, dragmacidin A-C, salacin and almazoles

Creator:: Tonsiengsom, Sorasaree
Abstract:: Studies toward the total syntheses of highly potent cytotoxic alkaloids including the bromopyrrole alkaloids and indole alkaloids were conducted and are described. Studies carried out in the course of this dissertation consist of five total syntheses of natural products that include bromopyrrole alkaloids nagelamide A, D and agelastatin D as...
