California and Steller sea lions (Zalophus californianus, Eumetopias jubatus, respectively) are considered sentinel species because they have long life spans, are long-term coastal residents, feed at high trophic levels, and have large blubber stores that serve as depots for anthropogenic toxicants. There are few studies on sea lion health and...
The objectives and characteristics of university biotechnology research, including its applicability to such industries as agriculture and food processing, arise from formal and informal linkages among university scientists, public and private-nonprofit funding sources, and industry. In the present study I develop, specify, and estimate a model of the supply and...
People in the US and Europe eat the most meat worldwide, lose or waste about 20% of this product overall, and they waste the most food per capita. Food waste is currently addressed as an issue of volume, so programs and policies target foods that are wasted more by weight...
This study analyzes public participation in nine regional hearings and six public meetings held by the U.S. Commission on Ocean Policy (USCOP) from September 2001 to April 2003. While several researchers have examined whether certain public involvement methods are considered successful or fair, this study characterizes the participants in a...
River basins provide essential services for both humans and ecosystems. Understanding the connections between ecosystems and society and their function has been at the heart of resilience studies and has become an increasing important endeavor in research and practice. In this dissertation, I define basin resilience as a river basin...
Intact sagebrush communities in the Great Basin are rapidly disappearing due
to invasion of non-native plants, large wildfires, and encroachment of pinyon pine
and juniper woodlands. Land management options include the use of prescribed
fire, grazing, herbicides and mechanical treatments to reduce the potential for
wildfire and restore plant communities....
This study addresses the question: "What are the incentives and disincentives for conflict prevention and mitigation in the Bureau of Reclamation (Reclamation), and how do they factor into Reclamation's management of water in the western United States?" Incentives and disincentives for conflict prevention (i.e., actions taken to avoid conflict) and...
The management of the Northern Rocky Mountains (NRM) gray wolf population is a longstanding controversy that has fueled generations of political and cultural turmoil in the American West. At the end of the 19th century and beginning of the 20th century, wolves were eradicated from the West for the threat...
With 97% of the world’s freshwater resources stored underground, the connection between groundwater resources to the metrics of space, scale and time common to the geographic study of natural resources has not been extensively investigated by geographers. While nearly 240 transboundary aquifers are mapped across the world, a potential “tragedy”...
Floods are the most frequent and damaging of all types of natural disasters and annually affect the lives of millions all over the globe. However, researchers seem to have overlooked the fact that floods do not recognize national boundaries. Therefore, the phenomena of shared, or transboundary floods occurring in international...
