Chronic heavy alcohol consumption is a risk factor for cortical bone fractures in males. The increase in fracture
risk may be due, in part, to reduced bone quality. Intracortical (osteonal) bone remodeling is the principle
mechanism for maintaining cortical bone quality. However, it is not clear how alcohol abuse impacts...
The Western Pacific Ocean barred knifejaw Oplegnathus fasciatus was found from 2013 to 2015 along the Pacific Coast of North America from Washington to California. The knifejaw was found in derelict vessels that had arrived on the Pacific Coast and that had been lost during the March 2011 Great Japan...
This qualitative study explored the gendered professional experiences of male elementary school counselors.

More than 2,000 male newts were collected during the summer
and maintained unfed at 10°C both pre- and post-irradiation.
Exposures ranging up to 30 kR were given with 300 kVp X-rays and
⁶⁰Co gamma rays. Half of the newts were injected (I. P.) with 15 g
DMSO/kg (the maximum sublethal...
Lucina floridana is an intertidal clam that contains intracellular, sulfur-oxidizing
symbiotic bacteria in its gills. These bacteria are chemolithoautotrophic, using the energy
from the oxidation of reduced sulfur compounds to power carbon fixation. Although
sulfide is an energy-rich compound, it is also toxic to aerobic metabolism and autooxidizes
in the...
The Great Tohoku Earthquake and Tsunami of March 2011 generated nearly 1.5 million tons of floating debris. After 1-5 years of drifting with the currents across the Pacific, many debris items reached the NE Pacific coast carrying Japanese marine species that could colonize our shores. More than 84 marine algal...

A floristic study of marine macrophytic algae and Cyanobacteria in the splash and intertidal zones at Luhuitou reef, Sanya Bay, Hainan Island, China, was conducted during the rainy and dry seasons of 2008-2012 utilizing 148 of the most common species. Macrophytic algal diversity increased from the splash zone to the...
This is an integrated assessment across terrestrial, freshwater, and coastal marine realms. It includes the coast range of Oregon and Washington as well as Vancouver Island in British Columbia. The marine portion only includes the coastline and shallow subtidal; the next iteration will include the offshore component.
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...

Following surveys of seaweeds in Oregon and the Caribbean, four algal species were selected for study on the basis of their crude extract biological activity or thin-layer chromatographic characteristics. Extracts were fractionated by normal phase chromatography, including high performance liquid chromatography (HPLC). Derivatives (methyl esters, acetates, and benzoates) of natural...
In 1982 a protohistoric archaeological site along the Applegate River in southwest Oregon was excavated by Oregon State University Department of Anthropology. Three housepits and a possible menstrual but were uncovered with lithic, faunal, and archaeobotanical elements recovered from house floors and hearths. Seven botanical taxa were represented by carbonized...
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
Recognisable debris from the Great Tōhoku Earthquake and Tsunami of March 2011 began arriving on the coasts of Oregon and Washington, USA in June 2012. This debris often carried fouling Japanese marine algae, and there was concern that these species might recruit and invade northeast Pacific shores. From June 2012...
To determine if 6 weeks prior supplementation with vitamins E and C

Lymphomas and leukemias are the most common cancer in children and young adults and in utero exposure to carcinogens may contribute to the etiology of these cancers. A polycyclic aromatic hydrocarbon (PAH), dibenzo[a,l]pyrene (DBP), was administered to pregnant mice (15 mg/Kg b.w., gavage) on gestation day 17. Significant mortalities in...
The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

Reproductive physiology of South American camelids is unique, especially in comparison to other domestic animals.

Males are dribble ejaculators, and the camelid ejaculate is highly viscous making it nearly impossible to work with in vitro....
