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...

Fungitoxicity of silver salts

Creator:: Guilford, Roger Kirby
Abstract:: The demand for new fungicides to control plant diseases has led to experimentation with both previously used and newly developed fungicides. Silver, an older but little used fungicide, was selected for evaluation because of its high toxicity to microorganisms. Silver nitrate and a silver electrolytic cell were tested as potential...

Evaluation of the colonization and biofilm production by Burkholderia pyroccinia FP62 on geranium leaves

Creator:: Wallace, Patricia K.
Abstract:: The leaf surface is a stark environment for bacterial colonists with limited availability of nutrients, water and protected niches. Despite these limitations, a plethora of bacteria appear to have adapted ways to survive and flourish on leaf surfaces. One mechanism of survival is the formation of biofilms. Biofilms are a...

Functional groups, traits, and the performance of species in restoration

Creator:: Roberts, Rachael E. (Rachael Elaine)
Abstract:: In ecological restoration, species that are sown to increase the native plant diversity range in establishment ability. Some species readily establish, while others rarely do. This study set out to investigate some of the potential processes influencing species establishment, as well as the traits that are associated with the success...

An Interdisciplinary-Botanical Perspective for Cultural Resource Management: A Definition and the Application of Culturally Significant Plants in Identification, Interpretation, and Evaluation for the National Register of Historic Places

Creator:: Burk, Rene F.
Abstract:: Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...

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...

Synecology of the white-oak (Quercus garryana Douglas) woodlands of the Willamette Valley, Oregon

Creator:: Thilenius, John F., 1931-
Abstract:: Quercus garryana dominated plant communities are found in the interior coastal valleys and on foothills from southeastern Vancouver Island, British Columbia, south to San Francisco, California. They occur as savannas, intermixed with a variety of conifers, and in almost pure stands. The diversity of habitats occupied by the species and...

Genetic variability in the eastern filbert blight pathosystem

Creator:: Osterbauer, Nancy K.
Abstract:: The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...
