This paper discusses research concerning redware vessel sherds found in an archaeological excavation at Oregon's historic Champoeg State Park, and comparative artifacts from four known Oregon and Washington late nineteenth pottery production sites. Visual and Instrumental Nuclear Activation Analysis comparison studies were conducted on samples from each site. The New...

The bi-directional relationships within the personal and contextual environments of adolescents are critical to the development of adolescents and their transition into adulthood. Opportunities for youth to participate in and provide leadership in meaningful programs, gain life skills, and interact with adults in sustained relationships are key features leading to...
Polycyclic aromatic hydrocarbons (PAHs) are a re-emerging class of environmental pollutants. The persistent nature of these highly toxic compounds along with their ubiquity in the environment creates an unavoidable route of exposure. The developing fetus and neonate are a particularly susceptible population due to their incomplete complement of xenobiotic metabolizing...
This report and especially the accompanying Detail Files and MapFiles provide relatively detailed information on status, trends, distribution, limiting factors, and conservation needs of all of the Willamette’s wildlife species, listed plants, and vulnerable habitats. Data on habitat suitability for each species is provided by watershed (170 HUC6s), elevation (6...
This thesis details my investigations of marine cyanobacterial natural products that resulted in the discovery of thirteen new secondary metabolites, the isolation of over fifteen previously reported metabolites and the biosynthetic investigation of two additional cyanobacterial compounds. Two novel lipopeptides were identified from a Lyngbya majuscula and Schizothrix sp. assemblage...
Electrical energy storage devices are currently the main limiting factor in many electrical devices and with the increasing demands placed on electrical power over fossil fuels, high energy density materials are essential. Previous research by Huang et al. on bulk (1-x)Bi(Zn₁/₂Ti₁/₂)O₃-xABO₃ solid solution systems led to the discovery of an...
Natural events such as wildfires, floods, and storms can significantly alter the short-term structure and functioning of natural systems. Recreation in wilderness areas is one instance in which individuals are directly exposed to post-disturbance landscapes. Consequently, public land managers may be faced with a different set of challenges stemming from...
To increase the knowledge needed to successfully implement the ecosystem-based approach to fishery management, this dissertation investigates important issues within the economics of choice and the economics of displacement. In particular, a discrete choice model of the fishing location decision in the Newport, Oregon bottom trawl groundfish fishery is estimated...
Protracted drought in the southwest U.S. has had significant impacts on the region’s keystone ecosystem, the pinyon-juniper (PJ) woodlands. Drought conditions in 9 of the last 10 years, exacerbated by extreme drought in one year, stressed the pinyon pine (Pinus edulis) trees, making them highly vulnerable to native ips beetles...
