A fistful of Astragalus : phenotypic and genotypic basis of the most taxon rich species in the North American flora

Creator:: Knaus, Brian J.
Abstract:: The study of the infra-specific ranks (i.e., subspecies and variety) can be considered the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxon rich species in the U.S. flora currently including 40 taxonomic varieties. These varieties were described using traditional taxonomic methods primarily...

The genetics of divergence and reproductive isolation between ecotypes of Panicum hallii

Creator:: Lowry, David B., Hernandez, Kyle, Taylor, Samuel H., Meyer, Eli, Logan, Tierney L., Barry, Kerrie W., Chapman, Jarrod A., Rokhsar, Daniel S., Schmutz, Jeremy, and Juenger, Thomas E.
Abstract:: The process of plant speciation often involves the evolution of divergent ecotypes in response to differences in soil water availability between habitats. While the same set of traits is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those traits evolve independently or if they evolve in tandem as...

Fragaria: A genus with deep historical roots and ripe for evolutionary and ecological insights

Creator:: Liston, Aaron, Cronn, Richard, and Ashman, Tia-Lynn
Abstract:: The cultivated strawberry, Fragaria Xananassa, is one of the youngest domesticated plants. Its 18th century origin via hybridization in Europe between the North American F. virginiana and the South American F. chiloensis was documented by the botanist Antoine Nicolas Duchesne. His 1766 “Natural History of Strawberries” is an extraordinary work...

Potential susceptibility of tanoak associated and rare ericaceous plant species of southwestern Oregon to Phytophthora ramorum

Creator:: Zanzot, James W.
Abstract:: The sudden oak death pathogen, Phytophthora ramorum, is present in southwestern Oregon, and while an eradication effort is underway, the potential impact of the polyphagous pathogen on surrounding vegetation is unknown. Plant communities in the area are substantially different from those affected in California, although tanoak (Lithocarpus densiflorus), evergreen huckleberry...

On the evolution of correlated color traits in garter snakes

Creator:: Westphal, Michael F.
Abstract:: How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...

Patterns and Variation in Benthic Biodiversity in a Large Marine Ecosystem

Creator:: Piacenza, Susan E., Barner, Allison K., Benkwitt, Cassandra E., Boersma, Kate S., Cerny-Chipman, Elizabeth B., Ingeman, Kurt E., Kindinger, Tye L., Lee, Jonathan D., Lindsley, Amy J., Reimer, Jessica N., Rowe, Jennifer C., Shen, Chenchen, Thompson, Kevin A., Thurman, Lindsey L., and Heppell, Selina S.
Abstract:: While there is a persistent inverse relationship between latitude and species diversity across many taxa and ecosystems, deviations from this norm offer an opportunity to understand the conditions that contribute to large-scale diversity patterns. Marine systems, in particular, provide such an opportunity, as marine diversity does not always follow a...

Landscape Genomics and Climatic Responses of Willamette Valley Alders

Creator:: Kral, George L.
Abstract:: The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...

Breeding and genetics of lilacs and hardy hibiscus

Creator:: Lattier, Jason D.
Abstract:: Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...
