Structure-forming invertebrates belong to a polyphyletic group of primarily sessile and sedentary megafauna that can significantly enhance the complexity of physical habitats. A number of these organisms, including cold-water corals and sponges, are known to be slow growing and vulnerable to physical disturbance. In addition, as filter feeders, these invertebrates...
Because of large declines in abundance of many Eastern Pacific rockfish populations (Genus Sebastes), there has been an increasing effort to improve our understanding of the role of spawning population characteristics and individual reproductive success in recruitment variability and population dynamics. Current methods for assessing sex and maturational status in...
Throughout society, many believe women are not succeeding professionally because of the institutional barriers created by men in the American workforce. However, women may be more competitive with other women than with men, especially when limited job positions are the goal. Competitiveness among women can be explained by a phenomenon...
This thesis employs the study of gender to demonstrate how recent Hollywood
western films have constructed a hero that is reflective of contemporary beliefs
regarding masculinity. Beginning with a New Historicist approach at studying gender,
this work first considers the construction of masculinity in post World War II America

State parks in Oregon provide important sites for visitor recreation and natural resource education. With the increasing number of visitors to Oregon coastal parks, tide pools and beach areas, there is growing need for site-specific marine education to enhance stewardship, interpretation and safety knowledge. The Oregon Sea Grant Program and...
The Pacific halibut has supported a major commercial fishery on the West coast of the United States for over 100 years. In the past, the halibut fishery was managed by a
policy of open access which led to an overcapitalized fishery and raised concerns about overfishing, fishing safety, and deteriorating...
This study delineates and characterizes the distribution of montane meadows in the Willamette National Forest, identifies encroachment patterns in relation to topographic features and proximity to trees in the Chucksney-Grasshopper meadow complex, and examines tree species and age distributions in relation to distance from forest edges or isolated tree clusters...
Thesis summarizes interviews with growers residing within the Groundwater Management Area (GWMA) in the Southern Willamette Valley of Oregon. Informal and semi-structured interviews were used to identify perceived impediments and incentives perceived by local farmers in following best management practices related to water quality. Results from the interviews were coded...
During the early 19th Century, the fur trade brought many Iroquois to the Pacific Northwest as working primarily as voyageurs for the North West Company. When the North West Company merged with the Hudson's Bay Company, the Iroquois employees merged as well. After retirement, some settled in the Willamette Valley...
Urban ecosystems are characterized by human disturbance and changes in the amount, types, and spatial arrangement of wildlife habitat. The relative importance of habitat and human associated variables to urban birds is unknown. In 1999, I surveyed spring bird and plant communities along 54 perennial streams
in the Portland, Oregon...
