Modeling and dating glacier fluctuations and their relation to Pacific Ocean climate

Creator:: Anslow, Faron S.
Abstract:: This thesis presents the results of an investigation into the interactions between the present-day South Cascade Glacier and the former Mauna Kea ice cap at short (annual to centennial) and long (millennial and multimillennial) time scales. To quantify the response of South Cascade Glacier to atmospheric conditions, a surface energy...

Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

Creator:: Pino, María-Teresa
Abstract:: Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

Soil carbon and nitrogen in old-growth forests in western Oregon and Washington

Creator:: Remillard, Suzanne Marie
Abstract:: Soil organic carbon (SOC, kg C m-2) is an important component in evaluating global C stores. The nitrogen (TN, kg N m"2) cycle is closely linked to C and understanding its role is also important. Contents and distributions of SOC and TN in soil profiles, to 1-meter depth, were estimated...

Entre crítica e imaginación: El contexto de las relaciones de México y Estados Unidos desde la perspectiva de La frontera de cristal y Gringo viejo

Creator:: Hansen, Tobin M.
Abstract:: What historical and political reality is reflected in the novels Gringo viejo and La frontera de cristal? What is revealed when the characters, plot, and setting of the novels are analyzed against research of the context of U.S.-Mexico relations? We begin to explore these questions by studying three periods crucial...

Spatial patterns of fuel management activities and their effects on wildfire behavior

Creator:: Kim, Young-Hwan
Abstract:: Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Control of alkane monooxygenase activity and expression in Pseudomonas butanovora

Creator:: Doughty, David M.
Abstract:: The regulation of monooxygenase enzymes has been demonstrated in bacteria that grow on methane and long chain-length alkanes (>C10). Less is known about monooxygenase regulation in short chain alkane oxidizing bacteria that grow on intermediate chain-length alkanes C2-C10. This dissertation focuses on the regulation of butane monooxygenase (BMO) expression and...

Response of soil microbial communities to physical and chemical disturbances: implications for soil quality and land use sustainability

Creator:: Chaer, Guilherme M.
Abstract:: The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...

Biotic barriers to colonizing new hosts by the cinnabar moth Tyria jacobaeae (L.)(Lepidoptera: Arctiidae)

Creator:: Karacetin, Evrim
Abstract:: The cinnabar moth (Tyria jacobaeae (L.), Lepidoptera: Arctiidae) is an icon in population ecology and biological control that has recently lost its shine based on evidence that (1) it is less effective than alternatives (such as the ragwort flea beetle Longitarsus jacobaeae (Waterhouse) (Coleoptera: Chrysomelidae) for controlling ragwort Senecio jacobaea...
