Phylogenetic Estimation and Ancestral State Reconstruction of Rubus (Rosaceae) using Target Capture Sequencing

Creator:: Carter, Katherine A.
Abstract:: Hybridization, polyploidy, and apomixis have made phylogenetic estimation in Rubus challenging. I used target capture to sequence approximately 1000 low copy nuclear loci and the chloroplast genome for 94 accessions representing the genus Rubus and distributed worldwide. Species phylogenies were estimated using two coalescent based methods, ASTRAL-II and SVDQuartets, and...

Organic soil amendements (sic) : impacts on snap bean common root rot and soil quality

Creator:: Cespedes Leon, Maria Cecilia
Abstract:: Common root rot is a major disease of commercially grown snap bean (Phaseolus vulgaris L.) on the irrigated sandy soils of central Wisconsin. The objective of this study was to determine the relationships between soil properties and suppressiveness to common root rot of snap bean (causal agent Aphanomyces euteiches) in...

Histological examination of Phytophthora ramorum in Notholithocarpus densiflorus bark tissues

Creator:: Botts, Molly M.
Abstract:: Colonization of N. densiflorus tissues by P. ramorum is not well understood. The pathogen is able to colonize nearly all tissues of this host but it is unclear how a tree is ultimately killed. Because this is such a destructive invasive pathogen, it is important to investigate its pathogenic strategy....

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,...

Colony Level Infection of Honey Bee Gut Pathogen, Nosema ceranae and Role of Pollen Nutrition in Nosema ceranae Infection and Bee Survival

Creator:: Jack, Cameron
Abstract:: Honey bees are important pollinators for many agricultural systems throughout the world. However, recent honey bee declines have caused great alarm, drawing attention to the vulnerability of worldwide agriculture to pollinator loss. These declines are often attributed to a combination of pests, pathogens, viruses, chemicals, and a lack of proper...

A Study of Urban Vegetable Garden and their Soils in Corvallis and Portland, OR

Creator:: Nelson, Michael, II
Abstract:: Urban agriculture (UA) is defined as the production of food crops or livestock within urban areas. Despite its popularity in the United States, research into UA systems suffers from a general underrepresentation of commercial urban systems. As a result, urban growers often have unique technological needs that are unmet by...

Mycological Maintenance of Rangelands and the Impacts of a Thatch Forming Invasive Annual Grass (Taeniatherum caput-medusae)

Creator:: Hovland, Matthew
Abstract:: Arbuscular mycorrhizal fungi (AMF) may exert profound influences on ecosystem resilience and invasion resistance in western North American sagebrush steppe and other arid rangeland plant communities. Maintenance of plant community structure through ecological feedbacks such as facilitation of nutrient cycling and uptake by host plants, physical and chemical contributions to...

Solarization in the Pacific Northwest: A Mathematical Field Model for Accumulation of Linearized Mortality from Variable Intermittent Heat

Creator:: Hill, Brian C.
Abstract:: Soil solarization trials were conducted during the growing seasons of 2016-2018 with the purpose of determining if solarization was an effective pre-planting soil disinfestation technique for tree nurseries in the Pacific Northwest. A large data set was collected on soil properties and biological indicators from 5 interdisciplinary experiments. This thesis...

Responses and relationships among Fusarium species, sweet corn, and western spotted cucumber beetles

Creator:: Miller, Nathan L. (Nathan Louis)
Abstract:: Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon have been declining since the early 1990’s. Studies were done to determine if there is a relationship between ear weight and several disease parameters including necrotic crowns or stalk nodes, nodal root rot, radicle root rot, and sub-crown...

Systematics, phylogeny, and biogeography of the hysterangiales and related taxa (Phallomycetidae, Homobasidiomycetes)

Creator:: Hosaka, Kentaro
Abstract:: Monophyly of the gomphoid-phalloid clade was confirmed based on multigene phylogenetic analyses. Four major subclades (Hysterangiales, Geastrales, Gomphales and Phallales) were also demonstrated to be monophyletic. The interrelationships among the subclades were, however, not resolved, and alternative topologies could not be rejected statistically. Nonetheless, most analyses showed that the Hysterangiales...
