A phenological examination of terrestrial invertebrate abundance at H. J. Andrews Experimental Forest, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Abstract Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...

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...

“The System is F*cked. Everything needs to Change:” A Queer Feminist Pro-Sex Work Analysis of the Digital Age

Creator:: Barrett, Emerson LR
Abstract:: “The system is fucked. Everything needs to change” was stated by Ashley Paige, a professional dominatrix and author in We Too: Essays on Sex Work and Survival, at a book launch event. Paige’s sentiments are poignant and a call to action to all of us. Through this thesis, I will...

An evaluation of factors influencing the management of Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae)

Creator:: Kepler, Ryan M.
Abstract:: The black vine weevil (BVW), Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae) is a persistent pest of nursery operations in the United States, feeding on over 140 species of plants. The goals of this research were to 1) assess the behavioral response of BVW to a commonly employed insecticide bifenthrin (Talstar 0.2G®)...

Management of powder-post beetles, Dinoderus minutus F. in freshly cut bamboo

Creator:: Garcia, Carlos Manalo
Abstract:: The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and ftmgi associated with beetles were investigated. Finally, the...

Integration of Evolutionary Theory and Genomics to Understand Processes Involved in Host Adaptation and Divergence in Phytophthora Plant Pathogens

Creator:: Tabima, Javier F.
Abstract:: Modern plant pathology benefits from integrating methods and concepts from evolutionary biology. For example, evolutionary concepts are used to identify and examine species boundaries of plant pathogens, recognize processes underlying pathogen biogeography, identify traits that characterize emerging species, and discover new molecular interactions that originate under processes of selection. In...

Responses of foothill yellow-legged frog (Rana boylii) larvae to an introduced predator

Creator:: Paoletti, David J.
Abstract:: The consequences of species introductions into non-native habitats are a major cause of concern in the U.S. An introduced species may alter native habitats, cause economic damage, compete with natives for resources or prey on them. Of particular interest are the effects of predation by introduced fishes on native amphibians....

Impurities in a homogeneous electron gas

Creator:: Song, Jung-Hwan
Abstract:: Immersion energies for an impurity in a homogeneous electron gas with a uniform positive background charge density have been calculated numerically using density functional theory. The numerical aspects of this problem are very demanding and have not been properly discussed in previous work. The numerical problems are related to approximations...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...
