Eelgrass (Zostera Marina) Population Decline In Morro Bay, Ca: A Meta-Analysis Of Herbicide Application In San Luis Obispo County And Morro Bay Watershed, Tyler King Sinnott
Eelgrass (Zostera Marina) Population Decline In Morro Bay, Ca: A Meta-Analysis Of Herbicide Application In San Luis Obispo County And Morro Bay Watershed, Tyler King Sinnott
Master's Theses
The endemic eelgrass (Zostera marina) community of Morro Bay Estuary, located on the central coast of California, has experienced an estimated decline of 95% in occupied area (reduction of 344 acres to 20 acres) from 2008 to 2017 for reasons that are not yet definitively clear. One possible driver of degradation that has yet to be investigated is the role of herbicides from agricultural fields in the watershed that feeds into the estuary. Thus, the primary research goal of this project was to better understand temporal and spatial trends of herbicide use within the context of San Luis …
Phantom Ocean, Real Impact: Natural Surf Sound Experiments Alter Foraging Activity And Habitat Use Across Taxa, Ryan N. Wardle
Phantom Ocean, Real Impact: Natural Surf Sound Experiments Alter Foraging Activity And Habitat Use Across Taxa, Ryan N. Wardle
Master's Theses
A growing body of research focuses on how background sounds shape and alter critical elements of animals’ lives, such as foraging behavior, habitat use, and ecological interactions (Bradbury & Vehrencamp, 2011; Barber et al., 2010; Kight & Swaddle, 2011; Shannon et al., 2016). Much of this research has centered on the effects of anthropogenic noise (Dominoni et al., 2020; Francis & Barber, 2013; Ortega, 2012; Swaddle et al., 2015), but recent studies have also revealed that natural sound sources can influence animal behavior (Davidson et al., 2017; Le et al., 2019). Natural sounds, such as crashing surf, can create conditions …
Sensory Stressors Impact Species Responses Across Local And Continental Scales, Ashley A. Wilson
Sensory Stressors Impact Species Responses Across Local And Continental Scales, Ashley A. Wilson
Master's Theses
Pervasive growth in industrialization and advances in technology now exposes much of the world to anthropogenic night light and noise (ANLN), which pose a global environmental challenge in terrestrial environments. An estimated one-tenth of the planet’s land area experiences artificial light at night — and that rises to 23% if skyglow is included. Moreover, anthropogenic noise is associated with urban development and transportation networks, as the ecological impact of roads alone is estimated to affect one-fifth of the total land cover of the United States and is increasing in space and intensity. Existing research involving impacts of light or noise …
Influences Of Conservation Farming Practice Adoption Amongst Vineyards On The Central Coast Of California, Jazlyn Guerrero
Influences Of Conservation Farming Practice Adoption Amongst Vineyards On The Central Coast Of California, Jazlyn Guerrero
Master of Science in Environmental Sciences and Management Projects
Farming practices will require changes to reduce crop sensitivity to climate change, which is projected to cause extreme heat events, variable precipitation, extended periods of drought, and increasing presence of pest and disease. Conservation agricultural practices build farm resiliency to climate impacts by improving soil health, reducing erosion and sediment runoff, and improving water infiltration. Literature on the adoption of conservation agriculture practices find no universal factors that indicate adoption of practices but suggest that the adoption of practices can be better understood by investigating practices specific variables and farm level characteristics and their implications on adoption. Our objective is …
Agricultural Conservation Decision-Making Under Environmental Risk And Uncertainty On The California Central Coast, Diego Rivera
Agricultural Conservation Decision-Making Under Environmental Risk And Uncertainty On The California Central Coast, Diego Rivera
Master of Science in Environmental Sciences and Management Projects
Global climate change is a process that is, in part, caused by agricultural practices, and will adversely affect agricultural operations, especially vineyards. The objective of this project is to determine how viticulturalists in Paso Robles, California view global climate change and how they use conservation practices that combat climate change and prepare for the associated negative effects. Interviews were conducted with vineyard advisors and managers to determine what general risks associated with wine grape production exist for their operations, and whether wine advisors and producers perceive global climate change to be one of those risks. The interview responses were then …

Host Plant Resistance In Strawberries To Anthracnose And Colonization Of Crown And Root Tissue By Verticillium Dahliae And Macrophomina Phaseolina, Omar A. Gonzalez-Benitez
Host Plant Resistance In Strawberries To Anthracnose And Colonization Of Crown And Root Tissue By Verticillium Dahliae And Macrophomina Phaseolina, Omar A. Gonzalez-Benitez
Master's Theses
Strawberries are considered an important crop in California where in 2018 it was in the top 5 valued fruit and vegetable commodities valued at $2.84 billion accounting for 88% of the total U.S. production. Strawberry production can be severely impacted by soilborne pathogens that can affect strawberry roots, crowns and leaves which can result in plant mortality. As much as 50 to 60% mortality can occur in one field. Pathogens responsible for such losses include Colletotrichum acutatum (syn.C. nymphaeae), Macrophomina phaseolina and Verticillium dahliae. With the phaseout of methyl bromide, host resistance and an understanding of host-pathogen interactions …
Viable Renewable Energy Sources And Storage For The Retired Power Plant In Morro Bay, Ca, Teresa Netro
Viable Renewable Energy Sources And Storage For The Retired Power Plant In Morro Bay, Ca, Teresa Netro
Physics
This project will investigate renewable energy production and storage options possible for the Morro Bay Power Plant and provide a recommendation for the energy portfolio of the renovated site. These suggestions can be tested at the Morro Bay facility before being extended to the nearby Diablo Nuclear Power Plant.
Valorization Of Carrot Processing Waste, Alexandra M. Duval
Valorization Of Carrot Processing Waste, Alexandra M. Duval
Master's Theses
Commercial carrot processors produce up to 175,000 tons of carrot waste annually. Carrot Mash (CM) is the term referring to the waste by-product of peeled baby carrot processing. Transportation of carrot processing waste is expensive due to its high- water content (approx. 83-95%). High in bioactive compounds (carotenoids) and dietary fibers, it is expected that its conversion into a value-added by-product is of interest to the carrot processing industry. Hemicellulose-rich plant materials have proven to be a source of oligosaccharides, which are known for their beneficial prebiotic activity. The objectives of this research were to: 1) determine the effect of …
