A population of the Douglas-fir cone moth, Barbara colfaxiana
(Kft. ), was studied on the Buckhead Seed Production Area, Oakridge,
Oregon, during 1971 and 1972. A method of estimating cone and
insect populations is presented. Factors contributing to the mortality
of B. colfaxiana are discussed, with resinosis being the critical...
In this memoir, by alumnus and Zoology Department instructor William J. Gilstrap, the author details various aspects of his life, including: childhood in Missouri, student experience at Oregon Agricultural College (OAC) in the 1890s, and his medical practice in various Oregon locales. Gilstrap also describes in this narrative the origins...
While real-time hybrid simulation has been utilized for structures subjected to seismic events for decades, its use in fluid-structure interaction problems is still a novel endeavor. Gathering data for cascading seismic and tsunami events is difficult due to space constraints in existing experimental facilities, complications regarding the application of scaling...
Gaps in the forest canopy allow more light to reach the understory. Since
light in the understory is heterogeneous, understanding the physiological
processes in gaps and non-gaps will improve estimates of carbon balance. This
research outlines an approach for defining carbon balance for Salal (Gaultheria
shallon Pursh.), a dominant understory...
Located on the central Oregon coast, the Umpqua Eden site (35D083) yielded an artifact assemblage which is one of the five largest assemblages from the Oregon coast. The first aspect of the site that I looked at is the people who lived at the site, the ancestors of the Confederated...
Many diseases cause a heavier burden on women than on men; however, treatment guidelines are based largely on data on men (NCBI, 2012). It becomes obvious that certain differences in genetics between men and women account for specific sex-related diseases, but there is too spare research focus on that issue....
Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...

The purpose of this study was to determine if the inferences derived from
the Kingore Observation Inventory as a screening device are sufficiently valid for
the identification of potentially gifted youngsters. Differences in predicting the
WISC-III Full Scale IQ scores and/or percentile ranks using the KOI were
assessed.
The value...
