The evolutionary stability of partial migration

Creator:: Ohms, Haley A.
Abstract:: Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...

The combined effects of vegetation control and seedling size class on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedling productivity on a site in Oregon

Creator:: Lefebvre, Robert F.
Abstract:: Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...

Mjesto - An Android Parking Locator and Reminder Service

Creator:: Carson, Aidan S.
Abstract:: Parking around Oregon State University campus can be severely limited, and for students looking to spend all day studying and going to classes it can be a pain to find parking that lasts for more than two hours. This thesis aims to resolve these issues by developing an application called...

Psychedelics and Entheogens : Implications of Administration in Medical and Non-Medical Contexts

Creator:: Kirk, Hannah R.
Abstract:: Psychedelics and entheogens began as religious sacraments. They were apotheosized for their mind-expanding powers and were thought to open realms to the world of the Gods. It was not until the first psychedelic compound was discovered in a laboratory setting a mere hundred years ago that they entered into formal...

Compatible Discretizations for Maxwell's Equations with General Constitutive Laws

Creator:: McGregor, D. A.
Abstract:: In this thesis we construct compatible discretizations of Maxwell's equations. We use the term compatible to describe numerical methods for Maxwell's equations which obey many properties of vector Calculus in a discrete setting. Compatible discretizations preserve the exterior Calculus ensuring that the divergence of the curl and the curl of...

The influence of sex, migration distance, and latitude on expression of anadromy in Oncorhynchus mykiss

Creator:: Ohms, Haley
Abstract:: The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...

Enhanced inverse synthetic aperture radar imagery using 2-D spectral estimation

Creator:: Ohm, David R.
Abstract:: This research focused on the use of classical and modern two-dimensional spectral estimation techniques for enhancing inverse synthetic aperture radar (ISAR) imagery. 2-D Classical spectral estimation methods and 2-D modern parametric and non-parametric spectral estimation methods are applied to simulated and real data sets in order to achieve both range...

Three essays on constrained markets

Creator:: Siegel, Ryan
Abstract:: The three essays in this dissertation progressively answer the following questions: (a) How important are constraints? (b) Who benefits from removing constraints? (c) When does a constraint for a single market predominantly affect closely related markets? These questions are applied in the context of time, weather, and minimum wage constraints,...

Perceptions of High School Student Athletes and Non-Athletes, Teachers, and Administrators Relevant to the Drug and Alcohol Prevention Policy: A Case Study

Creator:: Hess, Ashleigh E.
Abstract:: In public high schools, drug and alcohol prevention programs and policies have been ineffective in their deterrence of drug and alcohol use and abuse (Skager R., 2007). It is important to consider the needs of students and to create an effective, student centered drug and alcohol prevention program and policy....
