The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...
This thesis documents a period of ecological and cultural change on a Willamette Valley, Oregon landscape. In particular, this study examines the Peavy Arboretum area and the cultural changes that accompanied the transformation of the landscape from an oak savannah in the mid-nineteenth century to a dense Douglas-fir forest in...
The Seventh Annual James A. Vomocil Water Quality Conference was planned after three topics had been selected as being of particular interest. Wetlands, Best Management Practices, and Riparian Zone Effectiveness were the topics. Speakers were invited who by virtue of their training, their experience, or their work assignment had insights...

Over the last decade a new perspective on how forest ecosystems operate has emerged. Ecosystems appear much more flexible than we once thought. Even the most persistent is still evolving in composition. Yet for all their diversity, very similar processes are seen as operating in all forests, providing a point...
Little is known about non-industrial private forestland (NIPF) owners in relation to Oregon’s two primary preferential forest property tax programs: Forestland Program – the default tax program for many forestland owners, and Small Tract Forestland Option (STF) – a voluntary program wherein landowners pay reduced annual property taxes and an...
Mammalian skin is the largest organ of the body and serves as a barrier to protect the body against chemical, mechanical and pathogenic insults as well as water loss. The epidermis is formed from the primitive ectoderm into a multilayered stratified epithelium, consisting of basal, spinous, granular and outermost cornified...
Archaeological investigations can reveal persistent traditions of ethnic
groups. Hawaiians were employed in the fur trade of the Columbia River from
1810 through 1850. The Hudson's Bay Company employed them at Ft.
Vancouver, Washington from 1825 through the end of this period. Data from
the excavations of the servant's village...
This thesis is a rhetorical analysis of sexual harassment codes on college and
university campuses. The situational model proposed by Lloyd Bitzer is used to examine
representative artifacts from Rice University in Houston, Texas, and Oregon State
University in Corvallis, Oregon, so as to determine whether they operate as "fitting"...
The 13 personal essays in Water over Stones: Oregon Watershed Stories explore the author's experiences in dozens of Oregon watersheds. Using the genre of the personal essay, the author, a fifth-generation Oregonian and amateur ecologist, writes about her life and family relationships in stories that are saturated with the waters...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
Climate change has the potential to accelerate many forms of human migration and mobility, yet almost all of the key migration outcomes of interest are determined predominantly by governance, or the norms, laws, and institutions involved in the coordination of human society. These outcomes include the decision whether or not...
Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...
In spite of imperfections, this monograph is useful in locating bird skins collected along the Oregon Coast that are stored in about 80 museums. This monograph lists over 11,000 records of skins for 279 bird species and 192 records of skeletons for 52 bird species. Each record includes the species,...
Prior to advent of Europeans in the Pacific Northwest,
the Middle Columbia River Basin was the location of highly
developed native cultures. For centuries it was the center
of very important native trade networks that extended over
western North America and a site of important intertribal
rituals relating to renewal...

Metabolomics has recently gained momentum in biomolecule research and complements the genomics and proteomics research space. Metabolomics strives to detect, identify, and quantify all metabolites present in biological samples. In particular, biomolecular analysis using ultra-performance liquid chromatography combined with mass spectrometry (UPLC-MS) has become increasingly important for metabolomic analyses. Similarly,...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
A study was undertaken in the Willamette Valley, Oregon, to document
1971 land use patterns as well as land use change in a smaller study
area in the 16 years prior, and to relate these to soil characteristics.
Quantification of these inter-relationships was aided by use of computer
tabulation and...
The purpose of the workshop was to exchange information on sampling procedures, research methodologies, preparation and
interpretation of specimen material, terminology, and the application
and significance of findings, emphasizing the relationship of dendrochronology procedures to fire history interpretations.
Fort Yamhill, located in the eastern foothills of the Oregon Coast Range near modern day Grand Ronde, Oregon, was a U.S. Army post established in March 1856 as part of a three fort system to guard the newly established Coast Reservation and to provide a Union presence in the state...
Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...
The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
In this expanded new edition of Living with Earthquakes, Robert Yeats, a leading authority on earthquakes in California and the Pacific Northwest, describes the threat posed by the Cascadia Subduction Zone, a great earthquake fault which runs for hundreds of miles offshore from British Columbia to northern California. New research...
