The objectives of this investigation were two-fold: (1) to examine possible seed and cone characteristics and their usefulness as seed maturity indices, and (2) to examine the effects of artificial ripening on seed maturation and germination. Cone fresh weight, cone length, cone specific gravity, cone color, seed fresh weight, seed...
Metals are a persistent form of freshwater pollution and have been shown to bioaccumulate in aquatic macroinvertebrates through direct contact with contaminated water, sediments, and through consumption of contaminated organisms. This research explored the longitudinal bioaccumulation patterns of 5 common trace metals (Cr, Cu, Zn, Cd, and Pb) in the...
Although there is abundant scientific information regarding vitamin E and selenium deficiency disease in domestic poultry, there is only scant information on exotic species, such as ratites. Several necropsy cases involving ostriches, emus and rheas were presented to the Oregon State University Veterinary Diagnostic Laboratory with gross and/or histologic lesions...
In recent years, tsunami events have caused great devastation and loss of life around the globe. The coast of Oregon is highly vulnerable to a nearfield tsunami event caused by a Cascadia Subduction Zone earthquake, yet lacks a clear plan for evacuation and disaster mitigation.

Zalophus californianus (California sea lion), Callorhinus ursinus
(Northern fur seal),'and Phoca vitulina (Harbor seal). Ratios

The purpose of this study was to determine if a 5-month
progressive-resistance exercise program would affect measures
of activities of daily living (ADLs) and functional stability
in elderly women. All subjects were ambulatory women, 80 to
93 years old, who lived in assisted-care facilities. Eight
exercise and 7 control subjects...
L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
