Very little empirical research has been conducted on
Asian Americans as a whole in relation to their consumer
behavior, specifically their clothing behavior. A review of
literature demonstrated that Asian Americans have been
studied from different psychographic and sociological
aspects. However, the apparel shopping behavior of this
market has received...
Natality of black-tailed deer in McDonald State Forest was determined by examination of 147 reproductive tracts. Yearlings collected from November of 1968 to May of 1970 had an average of 0.79 corpora lutea per doe, and adults 1.76 corpora lutea per doe. Yearlings collected during the spring in 1969 and...
With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...
The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...

The freshwater polychaete Manayunkia speciosa was identified as an obligate host of the salmonid parasite Ceratomyxa shasta in 1997, prompting increased research on the small benthic invertebrate. Ceratomyxa shasta infection in fish can cause mortality, and presents a disease risk for both hatchery and wild salmon and trout. Ceratomyxa shasta...
Temperate coniferous forests, such as those that cover vast areas of the western US and Canada, have evolved to depend on cycles of disturbance for succession of species and overall ecosystem maintenance. Many of these forest systems are managed, often for timber production, where disturbances are of anthropogenic origin and...
Small hydrocarbon particles such as soot and soot precursors pose a serious threat to human health and Earth's climate. Understanding the mechanisms by which soot particles form and grow is the first step to reducing the prevalence of these particles. Computational simulations are used to investigate combusting systems which are...
When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....
The sustainable use of natural resources, including the goods and services provided by pasturelands and rangelands, is of growing importance due to climatic uncertainty and population growth.

I investigated the relationship between harlequin duck (Histrionicus histrionicus) behavior and lack of recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska. First, I evaluated the hypothesis that harlequin ducks in winter have little flexibility to increase foraging time in response to disturbance because they are constrained...
The dynamics of a field population of the cinnabar moth, Tyria
jacobaeae L., were studied near Jordan, Linn County, Oregon. In
both 1970 and 1971 larval populations were so large that all foliage of
the host weed, tansy ragwort, Senecio jacobaea L., was consumed.
The ensuing starvation accounted for the...

nannochir Gilbert 1891), two species have reduced swimbladders
(Lampanyctus ritteri Gilbert 1915 and Lampanyctus galis
Gilbert 1891), two species have gas-filled swimbladders
((Protomyctophum thomp soni (Chapman 1944)) and (Protomyctophum...
Similar to other spectacular scenic areas in the American West, Idaho’s White Cloud Mountains have been a contested landscape since the beginning of the 20th century. Although, legislation was introduced in Congress as early as 1913 to protect the towering mountains of south-central Idaho as a national park, the issue...
Many new research and monitoring projects, developed or initiated during ENSO 1982-83, constituted detailed descriptions of changes in specific taxa or specific processes. However, only a few projects were opportunely started or continued as regional efforts in the eastern Pacific. For those reasons, the information obtained is difficult to compare....
Title IX's passage into law in 1972 set women’s sports on a course toward gender equity with men's sports at the scholastic and collegiate levels, leading to a definitive growth in women’s professional leagues, corresponding athlete salaries, and athletic marketing and promotional prospects. However, disparities currently exist in the availability...
The 36 samples collected with a 22-foot semi-balloon shrimp
trawl at depths from 40 to 1,829 meters off the central coast of
Oregon between July 1961 and June 1962 provided preliminary data

Growth strata geometries and deformed geomorphic surfaces reflect the shorttimescale growth of Sierra de Villicum (San Juan Province, Argentina). Accumulated deformation in repeated earthquakes is recorded by the structural geometry of deformed geomorphic surfaces. Through geologic mapping and topographic surveying, six strath terraces were identified on the eastern flank of...
In this paper we present a model of Non-Euclidean geometry
in three dimensions. This will show that the axioms of Non-Euclidean
geometry are consistent if Euclidean geometry and, hence, arithmetic
is consistent. However, the model is incomplete for we have not
included the topic of congruence, the axiom of Archimedes,...
Environmental education programs seek to foster an appreciation for the natural world while introducing students to scientific thinking. Citizen science engages non-scientists in the systematic collection and analysis of data. The Betts Forest Landscape Ecology Lab combines both goals by inviting teachers in Corvallis, Oregon, and surrounding areas to participate...
Aligning Real-Time Networks (RTNs) with the National Spatial Reference System (NSRS) is crucial to ensure accuracy, consistency, interoperability, and long-term data integrity for geospatial applications.
