Abstract:
This dissertation examines the shrimp industry in the Gulf of California from a political ecology perspective. The interaction between fishermen and their marine environment is explored, as well as the historical factors that led to vastly different types of fishermen in the communities of Guaymas and Empalme. Some have specialized in the harvesting of shrimp; others are diversified, multiple species fishermen. Some are highly industrialized offshore shrimpers; others are small-scale fishermen, more modest in their technology but more resilient when facing the current crisis in the shrimp indu

This mixed methods research was conducted in the fall of 2014 to understand the perceptions and experiences of health risks and health outcomes due to pesticide exposure among community members (n=13) - concerned community members, agriculture workers and teachers- that live in the Central California agriculture counties of Monterey, Santa Cruz, Tulare, Fresno and Madera. This research explored: 1) The crops growing in participants’ communities, and how exposure to pesticides used in these crops pose potential health risks to participants and their communities 2) How pesticide exposure is impa

Abstract:
This study looked at the environmental factors present during testing for the spring 2004 administration of the California High School Exit Exam (CAHSEE) in an attempt to quantify some of the factors that were previously only qualitatively reported. Five factors were examined for their ability to predict passing percentages of students on the CASHSEE at the school level. The results indicated that socioeconomic status was the only significant predictor.

Abstract:
Dam removal is increasing as dams age, yet little is understood about the pedogenic response to dam removal. This study reports on the edaphic changes of reservoir sediments and vegetation cover one year following removal of a small earthen dam in Northern California. In August 2012, I sampled surface sediments from the former Dream Lake reservoir in Lassen Volcanic National Park, and compared their physical and chemical properties with soil samples from two reference sites. I also estimated percent cover of vegetation in the former reservoir and reference sites. My results show that the reser

Abstract:
Caffeine, a biologically active drug with many known molecular targets, is recognized as a contaminant of aquatic systems including marine systems. Although the concentrations of caffeine reported from aquatic systems are low (ng/L to μ/L), harmful ecological effects not detected by traditional toxicity tests could occur as a result of caffeine contamination. The goals of this thesis project were to: 1) quantify concentrations of caffeine occurring in the coastal ocean off of the Oregon Coast and to determine if higher levels were correlated with proximity to caffeine pollution sources; and 2)

Abstract:
Contaminants such as pharmaceuticals are of increasing concern due to their ubiquitous use and persistence in surface waters worldwide. Limited attention has been paid to the effects of pharmaceuticals on marine life, despite widespread detection of these contaminants in the marine environment. Of the existing studies, the majority assess the negative effects of pharmaceuticals over an exposure period of 30 days or less and focus on cellular and subcellular biomarkers. Longer studies are required to determine if chronic contaminant exposure poses risks to marine life at environmentally relevan

Abstract:
This study examines how community development and mainstream environmental groups form coalitions in state-level urban environmental legislation and the effect these coalitions have upon larger processes of institutional change. I argue that the alignment of community development and environmental interests is essential in the efforts to flatten the existing power hierarchy around land use decision-making and open up new possibilities for urban form. It helps to form a "counter-institutional" response which combines "pragmatic" and "purist" interests to resolve the social and environmental dil

Abstract:
Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level effects on reproduction and survival. Reproduction and survival were estimated annually, and an index of diet was inferred from pellet samples. A total of 11 adult males in 1998 and 22 in 1999 were successfully radio-tracked. Mean fixed

Evaporation ponds that dispose of agricultural drainwater provide attractive habitat for waterbirds but may result in contaminant exposure that impairs reproduction.

Avocets and Black-necked stilts (Himantopus mexicanus) comprised the majority of 5,969 nests found. Nest success and embryo mortality varied among ponds and between species.
