The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

Creator:: Zybach, Bob
Abstract:: The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

Unoccupied aircraft systems in forest monitoring applications

Creator:: Barker, Matthew I.
Abstract:: In recent years, unoccupied aircraft systems (UAS) have become increasingly affordable and straightforward to incorporate in monitoring applications of forested ecosystems. This shift has facilitated interest in using these tools to monitor aspects of forest ecosystems including vegetation health, forest structure and composition, and potential habitat provided by these systems....

An assessment of plant community structure, herbivory, soils, and state-and-transition theory on a winterfat (Krascheninnikovia lanata [Pursh] A.D.J. Meeuse & Smit) ecological site

Creator:: Matney, Casey A.
Abstract:: State-and-transition models (STMs) have been successfully used to describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...

Private forests, public policy : oak conservation on family forests in Oregon’s Willamette Valley

Creator:: Fischer, Alexandra Paige
Abstract:: In the United States, many of the thorniest natural resource conflicts occur on private lands. This is especially true in the Willamette Valley of Western Oregon where the hallmark habitat type, Oregon white oak woodland and savanna, is imperiled. Almost exclusively found on private land, Oregon white oak is threatened...

Marine herbivore-plant interactions : the feeding ecology of the sea slug Placida dendritica

Creator:: Trowbridge, Cynthia D.
Abstract:: The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...

Characterization of the pathogenicity and phylogeny of members of the Rhodococcus genus

Creator:: Creason, Allison L.
Abstract:: Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

Where have all the women and children gone? An examination of domestic life at the Newell Farmstead (35MA41) in the early Oregon country

Creator:: Manion, Mollie Jo
Abstract:: The Newell Farmstead (35MA41) archaeological site lies in the heart of the French Prairie in the Willamette Valley in the Champoeg State Heritage Area, Oregon. The integrity and depth of deposition have made the Newell site a unique opportunity to look at activity areas and domestic life of early Euro-American...

Factors affecting prolactin secretion in the African elephant

Creator:: Bechert, Ursula S.
Abstract:: Prolactin (PRL) is a peptide hormone that is involved in a number of diverse physiologic roles, particularly with respect to reproduction, including: influencing sexual and parental behaviors, onset of puberty, regulation of seasonal reproduction, follicular maturation, ovulation, luteinization and corpus luteum (CL) function, steroidogenesis, mammary gland development and lactation, testicular...

Honey Bees and Apple Trees : Hood River, Oregon as a Case Study for the Creation of the Honey Bee Pollination Industry

Creator:: Kellar, Brenda M.
Abstract:: The use of honey bees to pollinate apple orchards seems natural, even inevitable. This dissertation examines the relationship of beekeeping and apple growing in Hood River, Oregon in the mid-nineteenth to the mid-twentieth centuries, as a case study in the development of commercial pollination service. Within this time period the...

The economics of a research program : knowledge production, cost, and technical efficiency

Creator:: Qin, Lin
Abstract:: Calls continually are made to provide economic assessments of research program achievements and efficiency. Yet little effort has been given to develop an assessment framework that would focus on the research discovery itself, treating the research manager as a producer and the research technology as a knowledge production function. The...
