The presence of predators and competitors can offer biotic resistance against the establishment of non-native species, including the European green crab, Carcinus maenas, (EGC) in the estuary of Coos Bay, Oregon. It has been suggested that limb loss, or autotomy of the EGC will increase in areas that include populations...
The genus Phytophthora contains some of the most destructive pathogens of forest trees, including the most destructive pathogen of alder in recent times, Phytophthora alni. Alder trees were reported to be suffering from canopy dieback in riparian ecosystems in western Oregon, which prompted a survey of alder health and monitoring...
The purpose of this study was to collect information on relevant sexuality
education content for adolescents by assessing students' interests and
perceived needs. Subjects in this study were middle school students.
Two methods of data collection were employed, therefore, this study was
conducted in two phases. In the first phase,...
The height of an algebraic number A is a measure of how arithmetically complicated A is. We say A is totally p-adic if the minimal polynomial of A splits completely over the field of p-adic numbers. In this paper, we investigate what can be said about the smallest nonzero height...
Yellow starthistle (Centaurea solstitialis L.) is an introduced Asteraceae that has become established on 10 million acres in the Pacific Northwest and California. This weed functions as an annual or short-lived perennial and depends on seeds for reproduction. Strategies of control that reduce plant fitness or lower seed production or...
The increase in modern atmospheric CO₂ concentration (360 ppm) from
pre-industrial levels (280 ppm) raises concern over the impact of anthropogenic
carbon dioxide input on atmospheric chemistry. For this reason, it is important to
understand the natural fluctuations of atmospheric carbon dioxide in the past. The
Vostok ice core record...
The National Council of Radiation Protection and Measurements
Report No. 49, originally issued on September 15, 1976, has been the
primary design guide for diagnostic x-ray structural shielding in the
United States. To further protect the public from various areas of
medical radiation exposure, NCRP issued Report 116 in 1987...
There are three recognized species of Siphateles from the Great Basin; S. alvordensis, S. boraxobius and the tui chub, S. bicolor. One species, S. boraxobius, is endangered and one population of tui chub at Hutton Spring is threatened. Despite several morphological and molecular studies, the taxonomy and relationships of tui...
MySpace is a social network phenomenon with over 100 million profiles
and a strong presence in over 24 countries. As digital media become more
commonplace, social networks are becoming sites where women create and
manage relationships and identities. This thesis is a study of how women
ages 18-22 are constructing...
The objective of this study was to elucidate the expression of signaling molecules associated with the Wnt signaling pathway in cartilage of prepubescent foals and determine their association with chondrocytes located at the osteochondral junction and cartilage canals. Our hypothesis was that increased expression of the components of the Wnt...
