Phenotypic variation in diploid and tetraploid populations of Claytonia perfoliata (s.l.) (Portulacaceae)

Creator:: Miller, John M.
Abstract:: Meiotic chromosome counts from 200 populations of Claytonia (Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based on three morphologically different, chemically distinct, and geographically defined diploids. The basic chromosome number is x=6. Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid mature basal leaves ranges southeastward from...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Understory competition for resources in Pinus ponderosa forests of northeastern Oregon

Creator:: Riegel, Gregg M.
Abstract:: The objective of this research was to determine which environmental resources, light, water, and nutrients, control understory plant production and composition in a Pinus ponderosa forest in northeastern Oregon. A split-plot experimental design, with three blocks, four treatments, and 44 plots, was established in the summer of 1985. Twenty plots...

The influence of climate change and restoration on stream temperature

Creator:: Diabat, Mousa
Abstract:: Water temperature is an essential property of a stream. Temperature regulates physical and biochemical processes in aquatic habitats. Various factors related to climatic conditions, landscape characteristics, and channel structure directly influence stream temperature. Numerous studies indicate that increased average air temperature during the past century has led to stream warming...

An economic analysis of alternative water allocations and habitat investments for anadromous fish production, John Day Basin, Oregon

Creator:: Cerda, Arcadio Alberto
Abstract:: This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and steelhead trout) in the John Day River Basin,...

Cross-Laminated Timber Shear Walls with Toe-Screwed and Slip-Friction Connections

Creator:: Fitzgerald, Dillon M.
Abstract:: Timber engineering is currently in the midst of a significant evolution due to the rise of mass timber products, like cross-laminated timber (CLT). Increasing numbers of structural engineers are facing the challenge of designing lateral-force-resisting systems (LFRS) for multistory CLT structures. LFRS solutions such as steel frames, concrete cores, or...

Coordination and cooperation between community colleges and community schools in selected community college districts

Creator:: Weiss, Marvin Wesley
Abstract:: The most important purposes of this study were to: (1) determine the extent of cooperation and coordination that currently exists in selected community colleges which have community school programs in their college districts, and (2) clarify the multi-roles of community schools and of community education in community colleges. Other purposes...

Feeding Ecology and Growth of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) During Early Marine Residence

Creator:: Litz, Marisa Norma Chantal
Abstract:: The early marine phase following freshwater emigration has been identified as a critical period in salmonid (Oncorhynchus spp.) life history, characterized by high but variable mortality. Consistent with the “growth-mortality” and “bigger-is-better” hypotheses, at least some of the mortality during the critical period appears to be size-dependent – with smaller...
