Quantifying C and N contents and isotope signatures of SOM pools in the H. J. Andrews DIRT plots

Creator:: Keirstead, Heath
Abstract:: The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

The Relevance of Sexual Health Websites for African American Youth

Creator:: Barnard, Ke'ala J.
Abstract:: School-based comprehensive sex education (CSE) can reduce adolescent sexual health problems. However, only 49-55% of adolescents receive CSE that meets national standards. African American youth (AAY), particularly males, are less likely to receive CSE. AAY evidence a high prevalence of STIs/teen pregnancy. Internet-based CSE offers a supplemental option. We examined...

Spatial and temporal variability of absorption by dissolved material at a continental shelf

Creator:: Boss, Emmanuel, Pegau, W. Scott, Zaneveld, J. Ronald, and Barnard, Andrew H.
Abstract:: Optical properties of dissolved (colored dissolved organic material (CDOM)) and particulate matter and hydrographic measurements were obtained at the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. To assess the temporal and spatial variability, time series were...

The Role of Intraspecific Functional Trait Variation in the Differential Decline of Meadow Species Following Conifer Encroachment

Creator:: Celis, Jessica
Abstract:: In the Oregon Cascade Range, conifer encroachment has reduced the extent of mountain meadows by as much as 50% since the mid-1940s. Although encroachment results in a general decline of meadow species abundance and diversity, species differ in their sensitivities to encroachment: some show rapid declines whereas others persist in...

Investigations of gluten proteins from functional and historical perspective

Creator:: Zhang, Ying
Abstract:: Wheat (Triticum aestivum) is one of the world’s major staple food crops, with flour produced from starchy endosperm being used for breads, cakes, noodles and various other wheat-based foods. The unique bread making properties of wheat are primarily attributed to its gluten-forming storage proteins: gliadins and glutenins. This study investigated...

Essays on the economics of land use regulation

Creator:: Lai, Jiayin
Abstract:: This dissertation consists of three papers on land use economics and regulation. The first paper reviews numerous past literatures on how land-use regulation, agricultural subsidies, and use-value assessment method affect land values. The second paper uses a theoretical model to analyze how imposing minimum-lot-size zoning and different designs of minimum-lot-size...

Examination of moisture content variation within an operational wet deck

Creator:: Schimleck, Laurence, Love-Myers, Kim, Sanders, Joe, Raybon, Heath, Daniels, Richard, Andrews, Edward, and Schilling, Erik
Abstract:: Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...

Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

Creator:: Mazurkiewicz, Adam B.
Abstract:: The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

The higher classification of the Hesperiidae (Lepidoptera: Hesperioidea)

Creator:: Warren, Andrew D.
Abstract:: A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...
