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...

Recovery of ectomycorrhizal fungus communities fifteen years after fuels reduction treatments in ponderosa pine forests of the Blue Mountains, Oregon

Creator:: Hart, Benjamin T. N., Smith, Jane E., Luoma, Daniel L., and Hatten, Jeff A.
Abstract:: Managers use restorative fire and thinning for ecological benefits and to convert fuel-heavy forests to fuel-lean landscapes that lessen the threat of stand-replacing wildfire. In this study, we evaluated the long-term impact of thinning and prescribed fire on soil biochemistry and the mycorrhizal fungi associated with ponderosa pine (Pinus ponderosa)....

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

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...

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 Influence of Environmental Value Orientation and Climate Change Beliefs on the Firewise Behaviors of Central Oregon Residents

Creator:: Weston, Daniel L.
Abstract:: Over the past two decades, the western United States has experienced many of the costliest and most severe wildfires in history. To mitigate the effects of the growing threats posed by wildfires, residents in at-risk communities are encouraged to protect their homes and property by adopting Firewise recommendations. This article...

Sources of variability in duration of anesthesia with brevital sodium in snakes

Creator:: Preston, Daniel L.
Abstract:: Variability in the depth and duration of anesthesia in individuals within a species is frequently observed, yet few studies have investigated its causes in reptiles. To evaluate the potential causes of variability in reptile anesthesia, I conducted experiments to test for effects of body temperature, body composition and time post-feeding...

Remotely Incorrect? Accounting for Nonclassical Measurement Error in Satellite Data on Deforestation

Creator:: Alix-Garcia, Jennifer and Millimet, Daniel L.
Abstract:: Research relying on remotely sensed data on land use and deforestation has exploded in recent years. While satellite-based measures have clear advantages in terms of coverage, the presence of measurement error within these products is often overlooked. Here, we detail the econometric implications of these errors when analyzing the determinants...
