Conservation biology of Perideridia erythrorhiza (Apiaceae) : experimental reintroduction and life history

Creator:: Roberts, Kimberly A.
Abstract:: An experimental reintroduction was performed to determine the best method to create new populations of the tuberous species Perideridia erythrorhiza, a rare vascular plant endemic to southern Oregon. Only a handful of sites are currently present, and many of these are subject to other land uses such as urban development...

Mitigating cyanobacterial harmful algae blooms : the role of plant humics

Creator:: Theis, Susan A. F.
Abstract:: Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....

An experimental reintroduction of Pleuropogon oregonus, a rare wetland grass native to Oregon

Creator:: Groberg, Matthew G.
Abstract:: Pleuropogon oregonus Chase is a rare wetland grass endemic to eastern Oregon. The species is composed of two widely separated populations, one in Lake County and one in Union County. In order to reduce the risk of extinction, the Oregon Department of Agriculture Native Plant Conservation Program initiated several reintroduction...

Characterization of a bacterial agglutinin from legumes

Creator:: Jasalavich, Claudia Ann
Abstract:: Leaves of Phaseolus vulgaris cv. 'Dark Red Kidney' and cv. 'Red Mexican U. I. 31', Phaseolus lunatus cv. 'Fordhook Bush 242', Phaseolus mungo cv. 'Berken', and Glycine max cv. 'Wilkin' have been shown to contain a factor which consistently agglutinated the saprophyte Pseudomonas putida; another saprophyte Pseudomonas fluorescens was agglutinated...

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...

Hybridization between Castilleja levisecta and C. hispida : Implications for Pacific Northwest Prairie Management

Creator:: Sandlin, Isaac J., III
Abstract:: Conservation conflicts may develop on restoration sites with multiple species recovery objectives. For example, on Pacific Northwest prairies, the co-planting of the diploid cytotype of the common native wildflower Castilleja hispida with the endangered wildflower C. levisecta has resulted in putative Castilleja hybrids on restoration sites, prompting fears that genetic...

The biology and pathogenicity of a sheath nematode Hemicycliophora similis Thorne, 1955

Creator:: McKewan, Jeanette Anne
Abstract:: A study, using greenhouse and laboratory experiments, was made of Hemicycliophora similis from Bandon, Oregon to determine: identity and morphometrics, time and development of a life cycle, host plant preferences and optimum environmental conditions for reproduction and pathogenicity. Morphometric investigations revealed discrepancies between the measurements of this nematode species and...

Toward a flexible and accurate approach to null network sampling

Creator:: Bright, Zachary A.
Abstract:: Null networks are a type of random graph that is favored for the analysis of a wide variety of real-world networks, including gene-regulatory networks, food webs, and species co-occurrence matrices. As a hypothesis-generating tool, null networks are invaluable because they can reveal network motifs and unusual large-scale properties of networks...
