Conservation of Rorippa columbiae : an evaluation of reintroduction potential through the study of germination ecology, propagation methods, and habitat requirements

Creator:: Kentnesse, Laura E.
Abstract:: Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...

Conservation of Oenothera wolfii (Onagraceae) : introducing a threatened plant into two protected locations in Oregon

Creator:: Currin, Rebecca E.
Abstract:: The showy biennial to short-lived perennial Oenothera wolfii (Munz) Raven, Dietrich & Stubbe (Wolf’s evening primrose) occurs in only a small number of isolated populations on the southern Oregon and northern California coast. This rare species is currently listed as Threatened in Oregon, and is considered a Species of Concern...

Contrasting Epiphytic and Ground Layer Macrolichen Communities along the Coast-to-inland Climatic Gradient in Oregon

Creator:: Glauser, Abby L.
Abstract:: Cyanolichens, lichens with a cyanobacterial photobiont, benefit our ecosystems by the fixation of atmospheric nitrogen into a usable form for other organisms. They are highly sensitive to air pollution and require liquid water for photosynthesis. Many cyanolichen species frequently occur on the ground in the Pacific Northwest, however, most macrolichen...

Phytophthora species and riparian alder tree damage in western Oregon

Creator:: Sims, Laura L.
Abstract:: The genus Phytophthora contains some of the most destructive pathogens of forest trees, including the most destructive pathogen of alder in recent times, Phytophthora alni. Alder trees were reported to be suffering from canopy dieback in riparian ecosystems in western Oregon, which prompted a survey of alder health and monitoring...

Studies to facilitate reintroduction of golden paintbrush (Castilleja levisecta) to the Willamette Valley, Oregon

Creator:: Lawrence, Beth A.
Abstract:: Golden paintbrush (Castilleja levisecta Greenman) historically inhabited the prairies of the Willamette Valley, Oregon. However, this Pacific Northwest endemic is currently restricted to eleven sites in the Puget Trough of Washington and British Columbia. Recovery criteria call for the establishment of new populations throughout the species historic range, including the...

Systematic, genomic, and transcriptomic analysis of mycoparasitic Tolypocladium species and their Elaphomyces hosts

Creator:: Quandt, C. Alisha
Abstract:: Fungi in the genus Tolypocladium are diverse in their host associations, but the predominant ecologies include parasites of the ectomycorrhizal genus Elaphomyces and pathogens of insects. The aim of this dissertation research is to examine the evolution of these fungi and their host associations. To accomplish this several lines of...

Evolutionary relationships and an investigation of sympatric speciation within Limnanthaceae

Creator:: Meyers, Stephen C.
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies of Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Understanding Host-Pathogen Interactions in the Sphaerulina musiva-Populus Pathosystem

Creator:: Dunnell, Kelsey Liann
Abstract:: Host-parasite interactions between the pathogen, Sphaerulina musiva, and its host, Populus spp., were examined in a series of studies. In the first study, variation in resistance of Populus nigra from 7 locations in Europe was differentiated based on the parameters cankers per cm and disease severity score. The analysis evaluated...

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...

Cryptogam communities in forest and steppe ecosystems of Oregon, USA

Creator:: Root, Heather T.
Abstract:: I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...
