The growth of a plant’s root system is essential for its survival. Preliminary observations suggest that a protein complex called the exocyst may play a role in the development of the root system by facilitating the growth of roots and root hairs. Previous work discovered a protein that potentially interacts...
Endogenous circadian clock regulation is essential to normal rhythmicity, particularly the timing of hormone release in the brain. In the context of mammalian reproduction, a surge of a specific hormone, gonadotrophin-releasing hormone (GnRH), initiates a surge of luteinizing hormone (LH) from the pituitary gland, which is required for ovulation in...
To examine the influence of forest management on wildlife immunity, the innate immune system of wild deer mice (Peromyscus maniculatus) inhabiting forest plots of different management intensities in the Oregon coast range was measured by bactericidal assay. Bactericidal activity was compared across three management levels, including 40-50 year old forest...
Adequate energy stores are essential for animal survival, and sophisticated neuroendocrine mechanisms evolved to stimulate foraging in response to nutrient deprivation. Food search behavior is usually investigated in young animals, and it is not known how aging alters this behavior. To address this question in Drosophila, we compared the ability...
It has been observed and documented that Pisaster ochraceus has very striking colors, but the reasons behind the coloration are still unknown. Three coloration categories were determined and used for a feeding trial study to investigate the effects of diet on coloration in Pisaster ochraceus. This study involved 30 hand...
Throughout Oregon State University, a permanent, publicly-owned art collection not only exists under the radar of most people's awareness, this collection is part of a state mandate in existence since the late 1970's and too manages to slip most people's awareness at all. It is the Percent for Art Collection,...
Most animals are active either during the day, night, or twilight, and transition periods between these times exhibit interesting behavior. Actions may be related to avoiding predators, seeking shelter, defending territory, feeding, or other interests. Herbivorous fishes on coral reefs, such as parrotfishes, forage constantly throughout daylight periods due to...
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a potent immunosuppressant, and suppresses many disease models including graft-versus-host (GVH), experimental autoimmune encephalomyelitis (EAE) and a model of type 1 diabetes in non-obese diabetic (NOD) mice (1-3). In this study, we show that the inflammation of the pancreas due to insulitis is not a systemic autoimmune...
