Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

An Enthnobotanical Analysis of Basketry

Creator:: Fluharty, Suzanne M.
Abstract:: The focus of my thesis is ethnobotany which seeks to examine botanical resources and their context within particular cultures. My ethnographic research identifies and interprets the cultural processes woven into Oregon's coastal basketry through spirituality, environmental habitats, and utilized plant species. This is augmented with botanical research addressing the question...

New perspectives on evolutionary relationships within Pinus (Pinaceae) and within subsection Ponderosae (subgenus Pinus)

Creator:: Willyard, Ann Nachreiner
Abstract:: A fossil-calibrated phylogenetic framework based on exemplars from each of the four taxonomic sections within Pinus was created using multiple nuclear and chloroplast loci. Calibration at the well-defined subgeneric split within Pinus with either fossil leaves and cones (ca. 45 million years ago) or fossil wood (ca. 85 million years...

Lichen distribution in Oregon coastal dune communities

Creator:: Leuthner, Shirley Mae
Abstract:: Distribution of lichens was studied at seven coastal dune sites in Oregon. Lichens were sampled in the dry stable, dry meadow, meadow, rush meadow, marsh, shrub and forest deflation plain communities. Observations were made of the standing water in the marsh community. Quantitative measurements were made of the percent organic...

Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus

Creator:: Syring, John V.
Abstract:: Data from nuclear ribosomal internal transcribed spacer regions (nrITS) and chloroplast DNA (cpDNA) have failed to resolve phylogenetic relationships in Pinus. To provide greater interspecific resolution, five low-copy nuclear genes were developed from mapped conifer anchor loci. Four genes were sequenced from species representing all Pinus subsections. Individual loci do...

Assessment of potato tuber blight caused by Phytophthora infestans

Creator:: Glass, Jenny Rebecca
Abstract:: Late blight, caused by Phytophthora infestans, is a devastating problem to potato production in many parts of the world. While the foliar phases of this disease are well characterized, tuber infection, leading to quality losses and disease perpetuation, is less well understood. Experiments were conducted during 1998 and 1999 in...

Phylogeny, cospeciation, and host switching in the evolution of the ascomycete genus Rhabdocline on Pseudotsuga and Larix (Pinaceae)

Creator:: Gernandt, David S.
Abstract:: The relative role of cospeciation and host switching in the phylogenetic history of ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the pathogenic...

Conservation biology of Plagiobothrys hirtus (Boraginaceae) : evaluation of life history and population enhancement

Creator:: Amsberry, Kelly
Abstract:: Plagiobothrys hirtus (Boraginaceae) is a state and federally listed endangered plant found only in Douglas County, Oregon. This vernal pool endemic has historically been threatened by agricultural conversion of seasonal wetlands in the Sutherlin area, and is currently being eradicated as habitat is lost due to the rapid urban development...
