Willamette Valley Prairie Restoration : The Native Seed Network and Sidalcea

Creator:: Lambert, Joshua K.
Abstract:: My internship was conducted with the Native Seed Network program within the Institute for Applied Ecology, a non-profit organization located in Corvallis, whose focus is education, applied research and active restoration and of native ecosystems. My internship goals were to increase my experience in applied restoration ecology and conservation biology...

Castilleja and Pedicularis are confirmed as telial hosts for white pine blister rust in whitebark pine ecosystems of Oregon and Washington

Creator:: Mulvey, Robin L.
Abstract:: The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...

Effect of iron on biological control of fire blight by Pseudomonas fluorescens A506

Creator:: Temple, Todd N.
Abstract:: Competitive exclusion has been the mechanism hypothesized to account for the biological control of fire blight disease of pear and apple by the bacterium Pseudomonas fluorescens A506 (A506). Recent laboratory assays demonstrated, however, that A506 produces an antibiotic that is toxic to the fire blight pathogen, Erwinia amylovora, when cultured...

Litter decay processes and soil nitrogen availability in native and cheatgrass-dominated arid rangelands

Creator:: Harrison, Kristen S.
Abstract:: As large-scale restorations of degraded rangelands are initiated, land managers need to understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum L.), have altered ecosystem processes. One way to assess such alterations is by observing differences in decay rates, since decomposition is determined by factors such...

Factors limiting the distribution of the sensitive lichen Usnea longissima in the Oregon Coast Range : habitat or dispersal?

Creator:: Keon, Dylan B.
Abstract:: The sensitive lichen Usnea longissima Ach., formerly a fairly common circumboreal species, has been extirpated from much of its range (e.g., Eastern Europe). Although the U.S. Pacific Northwest (PNW) remains a relative stronghold for the species, U longissima faces increasing pressure in the region from habitat loss, air pollution, and...

Effects of single and multiple stressors on communities of wheat and wild oats

Creator:: Pfleeger, Thomas G.
Abstract:: Most plant toxicology tests developed in support of environmental laws use a single stress applied to an individual plant. While tests using individual species or stresses require fewer resources and are easier to interpret, they are under increasing criticism for being unrealistic and missing important ecological interactions. The objective of...

Relationships of exotic species and wildfire to the threatened plant Silene spaldingii

Creator:: Menke, Carolyn A.
Abstract:: In the canyon grasslands of Garden Creek Ranch Preserve in Idaho, where the threatened plant Silene spaldingii occurs and invasion by the exotic species Centaurea solstitialis and Bromus tectorum is proceeding rapidly, I examined environmental and community patterns of site invasion, and evaluated the apparent influence of invasion on Silene...

Reevaluation of systematic relationships in Triticum L. and Aegilops L. based on comparative morphological and anatomical investigations of dispersal mechanisms

Creator:: Morrison, Laura A.
Abstract:: Comparative morphological and anatomical studies of the dispersal mechanisms characterizing the wheat complex (Triticum L. and Aegilops L.) have documented patterns of adaptive radiation which may have significance for evolutionary relationships. These patterns, which form an array of diverse types of diaspores among the diploid taxa, appear conceptually to have...

Mediation of conifer root growth by mycorrhizal fungi and plant growth regulators

Creator:: Scagel, Carolyn F.
Abstract:: Many mycorrhizosphere microorganisms can produce plant growth regulating compounds in vitro. Plant growth regulating compounds are known to mediate root growth and development. In reforestation practices, conifer tree seedling growth and survival are linked to rapid root growth and development after outplanting. Multifactorial experiments were conducted to document variations in...
