Synecology of the Monotropoideae within Limpy Rock Research Natural Area, Umpqua National Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: Four aspects of the ecology of members of the Monotropoideae (achiorophyllous Ericaceae, referred to here as "monotropes") are presented: (1) a clarified conceptualization of monotrope nutrition based on a detailed literature review, (2) the relationship of monotrope populations to the plant communities of Limpy Rock RNA, (3) a test of...

Biomass and community structure of sporocarps formed by hypogeous ectomycorrhizal fungi within selected forest habitats of the H. J. Andrews Experimental Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total...

A Bioecological Model of Grief Recovery : Theory and Test of the Model

Creator:: Romo, Daniel L.
Abstract:: A primary aim of bereavement research is to alleviate suffering and promote well-being at the junction of life and death for the survivor in an attachment relationship. Bereavement research in the last decade has focused primarily on examining grief recovery within the context of intrapersonal processes. This emphasis has often...

Reactions and stereochemistry of thiolato and sulfenato cobalt (III) complexes

Creator:: Herting, Daniel L.
Abstract:: This thesis describes a study of the synthesis, stereochemistry, and reactivity of cobalt(III) cysteinato (CyS) and related thiolato complexes. The preparation of [Co(en)₂CyS]⁺ resulted in a product solution containing a mixture of diastereomers in the ratio 2.3:1 (Δ:A). The isomers were separated by ion exchange chromatography, and their absolute configurations...

Real-time neutron radiography

Creator:: Newell, Daniel L.
Abstract:: A real-time neutron radiography system has been developed at Oregon State University which is capable of producing neutron radiographs of objects and events concurrent with the incident radiation. The purpose of this thesis is to demonstrate the feasibility of the real-time technique as a further application of neutron radiography at...

Breeding biology and early life history of the tufted puffin (Fratercula cirrhata)

Creator:: Boone, Daniel L.
Abstract:: The breeding biology and early life history of the Tufted Puffin (Fratercula cirrhata) were studied for two years on Goat Island, Curry County, Oregon. Artificial nest boxes were used to minimize disturbance and provide easy access to puffin eggs and chicks. Utilization of these boxes was 47.5% and 57.5% in...

Shrunken learning rates do not improve AdaBoost on benchmark datasets

Creator:: Forrest, Daniel L. K.
Abstract:: Recent work has shown that AdaBoost can be viewed as an algorithm that maximizes the margin on the training data via functional gradient descent. Under this interpretation, the weight computed by AdaBoost, for each hypothesis generated, can be viewed as a step size parameter in a gradient descent search. Friedman...

The economics of land gains taxation : the Vermont case

Creator:: Daniels, Thomas L.
Abstract:: Governments have employed special capital gains taxes to curb speculation in real estate and raise public revenue. Economic theory suggests that the introduction of a gains tax with a declining rate structure over time will induce prospective buyers to reduce their demand for land and will induce sellers to offer...

Cavity resources in Oregon white oak and Douglas-fir stands in the mid-Willamette Valley, Oregon

Creator:: Gumtow-Farrior, Daniel L.
Abstract:: Previous studies of bird communities in the mid-Willamette Valley, Oregon, indicated that Oregon white oak (Ouercus garryana) stands supported more cavity-using bird species than sympatric stands of Douglas-fir (Pseudotsuga menziesii). Mature Oregon oak stands are being harvested and few are regenerating. I compared cavity availability for hole-using fauna among 10...
