Experimental Evolution of Roundup Resistance in Outcrossing Populations of Saccharomyces cerevisiae

Creator:: Hanson, Chloe C.
Abstract:: Evolve & Resequence (E&R) experiments subject laboratory populations to environments controlled by investigators, who then document the phenotypic and genomic changes that take place over many generations. These experiments provide powerful tools for testing of a wide variety of evolutionary questions, especially questions about the nature of adaptive traits. While...

Determining novel control methods for cabbage maggot (Delia radicum) in the Pacific Northwest

Creator:: Dugger, Chloe D.
Abstract:: Cabbage maggot, Delia radicum (Diptera: Anthomyiidae) impacts the production of Brassicaceae crops worldwide. The larva feed on the roots of crops causing reductions in yields due to impaired root function and unmarketability of crops. Chemical and cultural management programs are commonly used to control cabbage maggot with varying rates of...

Design and Modeling Techniques for Impedance Based Flow Cytometry

Creator:: Dawes, Jacob
Abstract:: Microfluidic devices have enabled lab-on-a-chip (LOC) systems that allow for complex sample analysis and preparation in a compact form factor. One technology that may benefit from a microfluidic approach and further miniaturization is flow cytometry. Flow cytometry is an analysis technique for enumerating and characterizing populations of cells; this is...

Geologic structure and exhumation accompanying Yakutat terrane collision, southern Alaska

Creator:: Johnston, Sarah A.
Abstract:: The climatic and tectonic framework of the St. Elias orogen makes it an excellent place to study the interactions between tectonic processes such as deformation and erosive processes, in particular glacial erosion. One type of link between these processes, proposed by numerical models of orogenic development, is an effect of...

Time of insemination and oviposition as related to fertility of female domestic fowl

Creator:: Johnston, Norman Paul
Abstract:: Hens were artificially inseminated at 8:00 a.m., 4:00 p.m. and 11:50 p.m. Fertility was found to be significantly lower after 8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations. Slightly higher fertility...

The effect of selenium on chemical carcinogenicity in the rat

Creator:: Johnston, Weldon Kearney
Abstract:: One hundred and fifty-one weanling rats of both sexes were fed control diets or diets containing 160 ppm diethylnitrosamine (DEN) or 150 ppm N-2-fluorenyl-acetamide (FAA). The carcinogen level was calculated so that the LD₅₀ should be achieved at about 17 weeks. Each carcinogen treatment was incorporated with three different diet...

Relative abundance and habitat associations of small mammals in two forest types in southern Oregon

Creator:: Johnston, Aaron N.
Abstract:: I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...
