Factors affecting establishment and germination of upland prairie species of conservation concern in the Willamette Valley, Oregon

Creator:: Jones, Katherine D.
Abstract:: Identifying mechanisms that determine who lives and dies is the first step in developing successful restoration techniques for rare species and endangered habitats. We studied interactions that affect establishment of native plant forbs of conservation concern at the seedling stage to support the theoretical basis for restoration activities in Pacific...

Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

Creator:: Marsden, Katherine E.
Abstract:: The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

The effects of site preparation on native forb establishment in a wet prairie, Willamette Valley, Oregon

Creator:: Norman, Katherine N.
Abstract:: Wetlands and wet prairies are economically and environmentally valuable ecosystems, but many have been degraded or converted to other uses. As human understanding of wetlands' value has increased, restoration efforts have grown correspondingly. Restoration attempts use a diversity of methods, which often include seeding with native plant species. This thesis...

Some cytological aspects of streak mottle virus in Lilium speciosum Thunberg

Creator:: Elser, John Elmore
Abstract:: Cultivated lilies include many garden varieties in addition to the Easter lily, Lilium longiflorum Thunb. A popular member of the garden group is Lilium speciosum Thunb., whose leaves can be discolored by a virus symptom described as streak mottle. This disorder is characterized by dashes of chlorotic tissue interspersed with...

The Role of Intraspecific Functional Trait Variation in the Differential Decline of Meadow Species Following Conifer Encroachment

Creator:: Celis, Jessica
Abstract:: In the Oregon Cascade Range, conifer encroachment has reduced the extent of mountain meadows by as much as 50% since the mid-1940s. Although encroachment results in a general decline of meadow species abundance and diversity, species differ in their sensitivities to encroachment: some show rapid declines whereas others persist in...

The Role of Plant-soil Feedback in the Invasion of Brachypodium sylvaticum in Douglas-fir Forests

Creator:: Esterson, Andrew
Abstract:: Invasive plants have the capacity to transform landscapes and alter ecosystem function, causing significant economic and ecological damage. These effects include displacement and reduction of native flora and fauna, altered fire regimes, modification of biotic and abiotic soil properties, as well as local, regional, and global economic impacts. With such...

Silviculture Impacts and Population Genomics of Coniferiporia sulphurascens, the Causal Agent of Laminated Root Rot

Creator:: McMurtrey, Shawn
Abstract:: Within the Pacific Northwest, USA, root diseases of conifers are a major forest health concern. These diseases are primarily caused by basidiomycete fungi. These fungal associates play a vital role in carbon sequestration but also have a significant negative economic impact within the timber industry. As a result, research on...

Systematics of the genus Otidea in the Pacific Northwest

Creator:: Peterson, Eric T.
Abstract:: The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...
