Controlling woody vegetation in wetland prairies, 1994-1999

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: Wetland prairies of the Willamette Valley, among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native pest species. Because fire has been important in maintaining Willamette Valley prairies for at least 1000 years, prescribed burning is a top choice of managers for preventing encroachment of...

Demographic analysis of Erigeron decumbens var. decumbens, an endangered plant species of the Willamette Valley, Oregon: 1999 Field Studies

Creator:: Clark, Deborah Louise, 1950-
Abstract:: Erigeron decumbens var. decumbens, known only from the Willamette Valley of western Oregon, is listed as Endangered by the U.S. Fish and Wildlife Service and by the state of Oregon. In 1993 a long-term population monitoring program for Erigeron decumbens var. decumbens was initiated at Baskett Slough National Wildlife Refuge...

Effect of a broccoli green manure, soil solarization, and isolates of Verticillium dahliae on Verticillium wilt of agronomic and nursery crops

Creator:: Berlanger, Ingrid E.
Abstract:: Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...

Sequence determination and regional epidemiology of raspberry bushy dwarf virus (RBDV)

Creator:: Taylor, Susannah M.
Abstract:: Raspberry bushy dwarf virus (RBDV) is the sole member of the idaeovirus genus of plant viruses. It is a pollen-borne virus that economically impacts both red and black raspberries worldwide. Three strains of the bipartite RBDV have been reported. The common strain found in North America, South America, Australia, New...

Fescue taxonomy in the Pacific coast states

Creator:: Wilson, Barbara L.
Abstract:: Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...

Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:: Garrett, Karen A.
Abstract:: Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

A two-component regulatory system controlling antibiotic production by Pseudomonas flourescens Pf-5

Creator:: Corbell, Nathan
Abstract:: Tn5 mutagenesis of apdA (for antibiotic production) and deletion of gacA (for global antibiotic and cyanide) resulted in the same pleiotropic phenotype in Pseudomonas fluorescens (i.e. production of an array of secondary metabolites including the antibiotics pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol as well as a tryptophan-side-chain oxidase, hydrogen cyanide, and an...

Danebo Wetland Prairie Project Environmental Education Curriculum

Creator:: Windham, George, Wagner, Jan, Ruzicka, Angela, Clark, Deborah Louise, 1950-, Wilson, Mark V., and Lederman, Norman
Abstract:: One goal of this environmental education curriculum is that students will gain an appreciation of Willamette Valley wetland prairies, a threatened ecosystem, and will gain an understanding of the importance of protecting these wetlands. A second goal is that students will see first-hand the processes involved in conducting scientific field...
