Creator:: Pryor, William Joseph
Abstract:: A Cr₂0₃, and cellulose fibre mixture was used with cattle, in three grazing and two semi-restricted experiments, to study the mode of its excretion, the possibility of using it in a once-daily dosing and grab-sample regime to estimate fecal output and in a field experiment to test a hypothesis involving...

The detection of superoxide and implications for amyotrophic lateral sclerosis

Creator:: Robinson, Kristine M.
Abstract:: Mutations to superoxide dismutase were the first proven cause of Lou Gehrig’s disease (amyotrophic lateral sclerosis; ALS) implicating superoxide in the selective death of motor neurons that characterizes ALS. Nitric oxide competes effectively with superoxide dismutase for superoxide to form the powerful oxidant peroxynitrite. Endogenous formation of peroxynitrite can kill...

Effects of ultraviolet-B radiation on marine phytoplankton

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

The effects of pathogens, UV-B radiation, and introduced species on amphibians in the Pacific Northwest

Creator:: Kiesecker, Joseph Michael
Abstract:: I examined two amphibian communities to assess factors that may impact amphibian biodiversity. The results suggest that the potential factors which influence the maintenance of amphibian biodiversity are multi-faceted and thus, attempts to understand these factors must reflect these complexities. I investigated factors that influenced the susceptibility of western toad...

Responses of forest understory plants to burial by volcanic tephra from Mount St. Helens, Washington

Creator:: Antos, Joseph A.
Abstract:: The effects of burial by tephra (volcanic aerial ejecta) on forest understory plants were examined northeast of Mount St. Helens, Washington, in the area where the 18 May 1980 eruption deposited tephra but did not destroy canopy trees. At six sites along a tephra depth gradient from 2-15 cm, understory...

Stress, osmoregulation, and the hormone cortisol in yearling coho salmon, Oncorhynchus kisutch

Creator:: Redding, Joseph Michael
Abstract:: Freshwater (FW) and seawater (SW) acclimated yearling coho salmon, Oncorhynchus kisutch, were subjected to severe confinement stress in FW, SW, or a medium (1/3 SW) that was approximately isosmotic to the fish's blood. Chronic stress caused osmotic imbalances in FW and SW, but not in 1/3 SW. In SW, blood...

Orientation and homing of the brush rabbit

Creator:: Chapman, Joseph A.
Abstract:: A study of orientation and homing in brush rabbits, Sylvilagus bachmani ubericolor (Miller), was conducted on the E. E. Wilson Game Management Area 7 miles north of Corvallis, Oregon, between July 1967 and April 1969. Sixty-seven individual rabbits were fitted with radio-transmitters and returned to the field. Home ranges were...

Water relations, gas exchange, and growth responses of Douglas-fir seedlings to stresses associated with transplanting

Creator:: Joseph, Gladwin
Abstract:: The goal of this thesis was to determine the physiological mechanisms that link adverse preplanting treatments of Douglas-fir, such as exposure and root pruning, to the phenomenon of transplanting shock. The objective of experiments 1 and 2 was to measure the effect of exposure and pruning on the physiology and...
