Response of Soil Microbially Mediated Nutrient Cycling and Community Structure to Timber Harvest in the Pacific Northwest

Creator:: Danielson, Rachel E.
Abstract:: Forest harvest persists as one of the most globally important industries, and crucially provides raw wood products for both building and fuel materials. Mechanistically complex abiotic and biotic processes curb ecosystem recovery following timber harvest and it is of great importance to understand the effects of this practice on biogeochemical...

Towards a national map of soil liquefaction susceptibility : modeling with heuristic and geotechnical methods

Creator:: Lindsley, Adam E.
Abstract:: This study investigates the use of predictive mapping techniques as well as geotechnical criteria in developing a multiregional soil liquefaction model and subsequent maps. The maps were produced using National Cooperative Soil Survey data, in the gSSURGO format, combined with soil liquefaction data gathered from studies, articles, and traditional seismic...

Factors Controlling Soil Microbial Biomass and Bacterial Diversity and Community Composition in a Cold Desert Ecosystem: Role of Geographic Scale

Creator:: Van Horn, David J., Van Horn, M. Lee, Barrett, John E., Gooseff, Michael N., Altrichter, Adam E., Geyer, Kevin M., Zeglin, Lydia H., and Takacs-Vesbach, Cristina D.
Abstract:: Understanding controls over the distribution of soil bacteria is a fundamental Understanding controls over the distribution of soil bacteria is a fundamental step toward describing soil ecosystems, understanding their functional capabilities, and predicting their responses to environmental change. This study investigated the controls on the biomass, species richness, and community...

Dynamics of ammonia oxidizing archaea and bacteria populations and contributions to soil nitrification potentials

Creator:: Taylor, Anne E., Zeglin, Lydia H., Wanzek, Thomas A., Myrold, David D., and Bottomley, Peter J.
Abstract:: It is well known that the ratio of ammonia oxidizing archaea (AOA) and bacteria (AOB) ranges widely in soils, but no data exist on what might influence this ratio, its dynamism, or how changes in relative abundance influences the potential contributions of AOA and AOB to soil nitrification. By sampling...

Removal of molluscicidal bait pellets by earthworms and its impact on control of the gray field slug (Derocerus reticulatum Mueller) in western Oregon grass seed fields

Creator:: Gavin, W. E., Mueller-Warrant, G. W., Griffith, S. M., and Banowetz, G. M.
Abstract:: Slugs are common pests of grass seed fields in western Oregon and the current focus of repeated, and often unsuccessful, efforts by growers to control them using molluscicides. Here we document rapid loss of molluscicidal bait pellets to earthworms and the resulting adverse effects on slug control. Three years of...

Use of aliphatic n-alkynes to discriminate soil nitrification activities of ammonia-oxidizing thaumarchaea and bacteria

Creator:: Taylor, Anne E., Vajrala, Neeraja, Giguere, Andrew T., Gitelman, Alix I., Arp, Daniel J., Myrold, David D., Sayavedra-Soto, Luis, and Bottomley, Peter J.
Abstract:: Ammonia (NH₃)-oxidizing bacteria (AOB) and thaumarchaea (AOA) co-occupy most soils, yet no short-term growth-independent method exists to determine their relative contributions to nitrification in situ. Microbial monooxygenases differ in their vulnerability to inactivation by aliphatic n-alkynes, and we found that NH₃ oxidation by the marine thaumarchaeon Nitrosopumilus maritimus was unaffected...

The Hordeum Toolbox: The Barley Coordinated Agricultural Project Genotype and Phenotype Resource

Creator:: Blake, Victoria C., Kling, Jennifer G., Hayes, Patrick M., Jannink, Jean-Luc, Jillella, Suman R., Lee, John, Matthews, David E., Chao, Shiaoman, Close, Timothy J., Muehlbauer, Gary J., Smith, Kevin P., Wise, Roger P., and Dickerson, Julie A.
Abstract:: The use of DNA markers in public sector plant breeding is now the norm. Such markers are common across breeding programs and this commonality enables and enhances collaboration. Therefore, large collaborative research projects that measure several phenotypes across multiple environments coupled with the expanding amount of genotype data attainable with...

Persistence of soil organic matter in eroding versus depositional landform positions

Creator:: Berhe, Asmeret Asefaw, Harden, Jennifer W., Torn, Margaret S., Kleber, Markus, Burton, Sarah D., and Harte, John
Abstract:: Soil organic matter (SOM) processes in dynamic landscapes are strongly influenced by soil erosion and sedimentation. We determined the contribution of physical isolation of organic matter (OM) inside aggregates, chemical interaction of OM with soil minerals, and molecular structure of SOM in controlling storage and persistence of SOM in different...

Density fractions versus size separates: does physical fractionation isolate functional soil compartments?

Creator:: Moni, C., Derrien, D., Hatton, P.-J., Zeller, B., and Kleber, M.
Abstract:: Physical fractionation is a widely used methodology to study soil organic matter (SOM) dynamics, but concerns have been raised that the available fractionation methods do not well describe functional SOM pools. In this study we explore whether physical fractionation techniques isolate soil compartments in a meaningful and functionally relevant way...
