Agricultural practices influence the nutrient dynamics of soil and plants, which may take more than a decade to be expressed in the drylands. The nutrient supplying capacity of soil is a crucial component of sustainable agriculture, and hence, this study can play an important role in policy making for the...
Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...
Conventional pictures of nuclear interactions, in which the pion mediates the long/medium range part of the nuclear force, predict an enhancement of the virtual pion cloud in nuclei relative to that in the free nucleon. Jefferson Lab Experiment E91003 measured charged pion electroproduction from Hydrogen, Deuterium, and Helium-3. The longitudinal...
Background: The numbers of Southeast Asian women in higher education, whether within administration, teaching faculty, or counseling and student services are scarce. The specific needs of minority women go largely unnoticed and remain unaddressed and may contribute to the low numbers of minority women in higher education leadership.
Purpose: The...
Infectious diseases are a growing concern for both humans and wildlife. The negative effects of infectious disease have been exemplified by the recent global amphibian population declines associated with disease outbreaks. Although multiple pathogens and factors play a role in these declines, the aquatic fungal pathogen, Batrachochytrium dendrobatidis (Bd), has...
Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...
Female mink (Mustela vison) are highly sensitive to polychlorinated biphenyl (PCB)-induced reproductive impairment. The goal of this research was to develop a better understanding of the mechanism of PCB-induced effects on female mink, mink embryos, and surviving mink kits. Anestrous, juvenile female mink and pregnant, adult mink were exposed to...
The focus of this study was to examine the administrative legacy of two African American women administrators, Maxine Buie Mimms and Wintonnette Joye Hardiman, who administrated The Evergreen State College-Tacoma, Washington (TESC-T) campus for more than three decades. TESC-T is nationally known for its community-based curriculum and pedagogy, high retention...
