Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native
people whose frequent intentional burning of the landscape promoted open stands
dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century,
livestock grazing, and logging of the largest trees has resulted in forests characterized by...
Confederate governors Joseph Brown and Zebulon Vance have long been considered obstructionists to the Confederate cause through their steadfast commitment to states' rights. States' Rights Nationalists throws in its own interpretation of these two men into the historiographical conversation taken on by well-known Civil War historians like Frank Owsley, Albert...
Site ORYA3, the Smith House, is located in Dayton, Oregon. The archaeological project originated because owners of this structure, listed on the National Register of Historic Places, applied for a demolition permit. The 1859 home, first occupied by two early Oregon pioneers, Andrew and Sarah Smith, was considered architecturally significant,...
The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile)
to control broadleaf weeds in cereal crops has become widespread.
This herbicide has not always performed satisfactorily for reasons
which were not clearly evident.
The effects of temperature, light and humidity on the herbicidal
activity of bromoxynil on coast fiddleneck, Amsinckia intermedia,
were studied. Fiddleneck...
While much research has examined the intricate interactions associated with the harvesting of wild animals for human consumption, little work has been undertaken in attempting to understand the greater socio-cultural significance of such use. In addition, to properly understand such systems of interaction, an intimate knowledge is required with regard...
Seventy-two species of Blennocampinae in 21 genera and six tribes
are known from the Nearctic region. The adults and known larvae of
all species and genera are keyed, described and illistrated. A
definition of the subfamily, a review of previous work, a table of
host-plant associations, and a discussion of...
A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...
Rhizopogon vesiculosus is a common ectomycorrhizal (EM) symbiont of Pseudotusga menziesii (Douglas-fir) in the coast range of the Pacific Northwest. The species has been studied for its systematics, genet size, population structure, and competitive ability in several field and experimental studies. This thesis seeks to provide a more thorough characterization...
Fungi in the genus Tolypocladium are diverse in their host associations, but the predominant ecologies include parasites of the ectomycorrhizal genus Elaphomyces and pathogens of insects. The aim of this dissertation research is to examine the evolution of these fungi and their host associations. To accomplish this several lines of...
Rhizopogon is a large genus of ectomycorrhizal (EM) fungi that grows in association with host trees of the family Pinaceae. We have conducted a series of studies investigating the ecology and evolutionary biology of the EM symbiosis shared between R. subgenus Villosuli and trees of the genus Pseudotsuga. Two members...
