Anthropogenic activities have posed many threats to the oceans and marine life. Understanding how individuals are affected and physiologically respond to these threats is crucial and allows for management and conservation applications. I evaluated the overall health condition of a subpopulation of gray whales (Eschrichtius robustus) along the Oregon coast,...
The desire to understand the spatial and temporal drivers of animal behavior and distribution relative to scale is central to movement ecology. Optimal foraging theory states that a predator should continue exploiting a patch until it is no longer profitable to do so. As human developments increasingly encroach on the...
The present research was an exploratory study which investigated the marketing practices of textile-related, home-based business owners. Questionnaires were mailed to 204 textile-related, home-based businesses throughout the continental United States. The final response rate was 42 percent with 86 useable questionnaires. A five-point semantic differential scale was used to measure...
The search for archaeological materials dating to 15,000 yr BP along the southern Oregon coast is a formidable task. Using ethnographic, theoretical, and archaeological data, landscape resources which would have influenced land-use and occupation location decisions in the past are highlighted. Additionally, environmental data pertaining to the late Pleistocene is...
The social sciences are increasingly used in conservation to describe interactions and relationships between humans, wildlife, and ecosystems. Scientists and policy-makers have concluded that promoting human tolerance for wildlife is critical to the success of conservation efforts. Yet, the concept of tolerance is relatively new in the context of human-wildlife...
The marine environment is under increasing pressure from human activities worldwide, particularly in coastal waters, creating a need to better understand fine-scale distributions of highly mobile species that occur in the area, as they are frequently most threatened. Harbor porpoise (Phocoena phocoena) occur frequently in Oregon’s nearshore habitat, but due...
Ocean acidification (OA) has emerged as an important focus of research and policy in this decade. Ocean acidification specifically refers to changes in the inorganic carbon system in the ocean resulting from its absorption of human-released CO₂ from the atmosphere. Anthropogenic atmospheric CO₂ levels are rapidly increasing; much of this...
New detrital mica ages from the Umpqua Group of the Oregon Coast Range provide constraints on models of Eocene sedimentation. Based on sandstone petrography, previous studies assert that the Klamath Mountains to the south are the most likely source region for Umpqua Group sedimentary provenance. However, the presence of Late...
Regular null curves in Regular null curves in L³ always have a time component parametrization. This fact puts the Frenet equations for regular null curves in L³ in a simple form. A fundamental existence and uniqueness theorem for regular null curves in L³ is proved, and applications to geometry are...
The Thomas Kay Woolen Mill operated between 1890 and 1962. The mill produced predominately woolen blankets and woolen fabrics for outerwear garments. Mission Mill Museum Association purchased the woolen mill after its closure in order to develop the property as a museum. The purpose of this study was to provide...
