Food hubs are a key solution to advance local and regional food systems by providing aggregation, storage, and distribution services to small and mid-sized farmers and thereby help them to access local and regional markets. By performing these functions, food hubs produce valuable services to not only farmers but to...
The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...
The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...
Two indigenous species of burrowing shrimp inhabit and often dominate the intertidal zone of estuaries along the US West Coast, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species are considered ecosystem engineers and play a role in maintaining estuarine health and ecosystem function. They...
Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas
(RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...
Dysferlin is a ∼230 kDa terminally anchored membrane protein that is ubiquitously expressed, but is particularly enriched in skeletal and cardiac muscle tissue. Mutations covering the length of the protein have been linked to muscle wasting diseases including limb-girdle muscular dystrophy and Myoshi myopathy. Dysferlin has been shown to play...
In endurance-trained men, an acute bout of exercise is shown to suppress post-exercise appetite and alter changes in specific appetite regulating hormones. Limited research has examined these responses in endurance-trained women. PURPOSE: To investigate the effect of exercise intensity on the appetite regulating hormones acylated ghrelin, PYY and GLP-1 and...
African-born population is one of the fastest growing group in the United States. Very little is known about their socio-demographic characteristics, health behavior practices and long-term health. The purpose of this study was to examine hypertension prevalence, health behavior practices and the impact socio-demographic factors have on these outcomes among...
Childhood obesity and food insecurity are public health issues that often coexist, and both conditions are more prevalent among rural compared to non-rural populations. Social ecological prevention efforts are recommended, yet limited research has examined how rural family-home environments may influence obesity-preventing and -promoting behaviors. The purpose of this dissertation...
American Indians and Alaska Natives (AIAN) have more negative sexual and reproductive health outcomes than non-Hispanic whites. Little is known, however, about the factors that lead to sexual and reproductive health disparities for AIANs, including the role of sexual and reproductive health services (SRHS).
Logistic regression analyses were performed on...
