Ecological assessment after the addition of genetically engineered Klebsiella planticola SDF20 into soil

Holmes, Michael T. (1995-06-19)

The objectives in this research were to assess whether Klebsiella planticola SDF20 could survive in soil and result in ecological effects to soil foodweb organisms and plant growth. Four experiments were conducted usin ...
Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States

Lintz, Heather E. (2010-12-30)

Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why speci ...
Ecology and distribution of riparian vegetation in the Trout Creek Mountains of southeastern Oregon

Evenden, Angela G. (1989-06-22)
Ecology of benthic microalgae of estuarine intertidal sediments

Riznyk, Raymond Zenon (1969-05-09)

The benthic microalgae of sediments of the two tidal flats in Yaquina Bay, Oregon were investigated to determine the environmental factors limiting the abundance and the horizontal and vertical distribution of these o ...
Ecology of Corydalis aquae-gelidae, a rare riparian plant

Goldenberg, Douglas M. (1992-06-29)

Corydalis aquae-gelidae is a large herbaceous perennial in the Fumariaceae that has high habitat specificity. It is endemic to the western Cascade Range of Oregon and Washington, almost entirely on the Mt. Hood and Gi ...
Ecophysiology of the cyanolichen Lobaria oregana

Antoine, Marie E. (2001-10-30)

This thesis consists of three manuscripts describing ecophysiological research on the cyanolichen Lobaria oregana. The first manuscript includes a re-evaluation of the assumptions underlying past estimates of N fixatio ...
Effect of a broccoli green manure, soil solarization, and isolates of Verticillium dahliae on Verticillium wilt of agronomic and nursery crops

Berlanger, Ingrid E. (1999-11-22)

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 Iron Limitation on the Transcriptome and Proteome of Pseudomonas fluorescens Pf-5

Lim, Chee Kent; Hassan, Karl A.; Tetu, Sasha G.; Loper, Joyce E.; Paulsen, Ian T. (Public Library of Science, 2012-06-18)

One of the most important micronutrients for bacterial growth is iron, whose bioavailability in soil is limited. Consequently, rhizospheric bacteria such as Pseudomonas fluorescens employ a range of mechanisms to acquire ...
Effect of iron on biological control of fire blight by Pseudomonas fluorescens A506

Temple, Todd N. (2003-05-27)

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 de ...
Effect of nutrient enrichment on marine benthic diatoms in Yaquina Bay, Oregon

Cardon, Nanette Clark (1981-05-18)

Sediment was fertilized with f/2 algal growth medium in situ and in the laboratory daily for one week. Sampling strategy incorporated two intertidal heights and two sites. Experiments were done in August and January. ...
Effect of resident epiphytic fungi development of brown rot blossom blight of stone fruits

Wittig, Hans P. P. (1992-01-14)

Antagonistic effects of Epicoccum purpurascens, Aureobasidium pullulans, Trichoderma spp., and Botrytis cinerea on establishment of Monilinia fructicola infections in cherry and peach blossoms were assessed in field a ...
Effect of soil water pressures on population dynamics of Fusarium equiseti, Glocladium virens, Talaromyces flavus and Trichoderma viride, biocontrol agents of Verticillium dahliae in potatoes

Hussain, Shaukat (1994-02-23)
Effect of wheat cultivar mixtures on populations of Puccinia striiformis races

DiLeone, Julie A. (1993-01-28)

This study quantified the frequency of simple versus complex races of Puccinia striiformis Westend. in mixtures of wheat cultivars possessing different race-specific resistance genes. A simple race of a pathogen can i ...
The effect of zinc limitation on the transcriptome of Pseudomonas protegens Pf-5

Lim, Chee Kent; Hassan, Karl A.; Penesyan, Anahit; Loper, Joyce E.; Paulsen, Ian T. (Blackwell Publishing Ltd, 2013-03)

Zinc is an important nutrient but can be lacking in some soil environments, influencing the physiology of soil-dwelling bacteria. Hence, we studied the global effect of zinc limitation on the transcriptome of the rhizosp ...
Effectiveness of Vehicle Washing and Roadside Sanitation in Decreasing Spread Potential of Port-Orford-Cedar Root Disease

Goheen, Donald J.; Mallams, Katrina; Betlejewski, Frank; Hansen, Everett (Society of American Foresters, 2012-10)

Two techniques widely recommended for managing Port-Orford-cedar root disease (caused by the introduced pathogen Phytophthora lateralis) are vehicle washing and roadside sanitation. However, their effectiveness has never ...
The effects of defoliation on Bromus tectorum seed production and growth

Mayer, Kara Hempy (2004-07-15)

Cheatgrass (Bromus tectorum L.) is a widespread exotic weed in the Intermountain sagebrush steppe. An annual grass, it is highly prolific and very competitive with native perennial grass seedlings. A clipping experiment ...
Effects of fire on seedling establishment in upland prairies in the Willamette Valley, Oregon

Maret, Mary P. (1996-12-17)

Prior to European settlement, native prairie dominated the landscape of the Willamette Valley. Today, due to urbanization, agriculture, and the cessation of burning, only isolated remnants of these grasslands still exi ...
