Faculty Research, Scholarly, and Creative Activity

Aquaculture contributes approximately half of all global aquatic food production and will be critical in addressing future seafood demand, including the United States (U.S.). Many states, territories, and countries are developing and updating aquaculture specific policy in an effort to plan for, and better manage the expansion of aquaculture in their territorial waters. The U.S. has considerable potential to sustainably expand aquaculture production, which has been a focus in both federal and state policy. State aquaculture plans have been used for over 40 years to help plan and coordinate aquaculture development, with a growing emphasis on sustainability. Here, we located …

Faculty Research, Scholarly, and Creative Activity

Owing to the historical patterns of colonialism and settlement, many of the remaining undeveloped mineral resources needed for a low-carbon energy transition are located on lands that have historic, ancestral, or cultural significance to Native American Tribes and Indigenous communities, as well as are near environmental-sensitive areas. While some mining projects occur on private land, the majority of mining projects are proposed for lands owned by the United States Federal Government and managed by multiple agencies (United States Forest Service, Bureau of Land Management etc.) with goals across the spectra from natural resource development to cultural resource conservation. Through a …

Private Landowner Interest In Prescribed Fire In California: Findings From Workshops In The Sierra Nevada, Kate M. Wilkin, Amanda M. Stasiewicz, Susan D. Kocher

Faculty Research, Scholarly, and Creative Activity

Background: Globally, prescribed fire political interest and practice has been rekindled following recent devastating wildfire seasons. This phenomenon was especially acute in areas with dual wildfire and forest health crises, like California. Previous research has investigated prescribed fire on public lands or on private lands in other regions, but little is known about prescribed fire practice or interest on private lands in California. Therefore, we sought to understand private land managers’ perceptions of prescribed fire compared to other land management techniques, treatment pathways, motivations, and barriers to complete these treatments in California. Results: Before workshops on prescribed fire for private …

Using Moss As An Inexpensive Air Pollution Bioindicator For Environmental Equity In Santa Clara Country, California, Tam Dan Tran

Master's Theses

Toxins pervade urban areas and pose long-term health risks to humans. I examine moss as an affordable bioindicator and assess whether moss monitor results reflect other air quality (AQ) indicators, environmental factors, and social vulnerability. Specifically, I investigate (1) whether moss is an effective atmospheric pollution indicator and (2) whether low-income or high-lead-risk neighborhoods experience greater exposure to air pollution. I set out Hypnum cupressiforme moss for two months of exposure in 28 Santa Clara County locations and then measured chromium, zinc, nickel, and the loss of chlorophyll fluorescence in the moss tissue. I gathered real-time particulate matter (PM2.5) measurements …

Mammal Response To Wildfire In Redwood Forests In Northern California, Kristine Doerr

Master's Theses

California has historically experienced recurrent wildfires that have shaped many of the region’s unique ecosystems such as coast redwood (Sequoia sempervirens) forests. Redwood forests, particularly old-growth redwoods, are vital habitats for many wildlife species. Still, these long-living, fire-resistant trees are facing altered fire regimes due to fire suppression and climate change. The 2020 CZU Lightning Complex Fire was a consequence of these changes and significantly altered the landscape of the Santa Cruz Mountain region. This study analyzes mammal recovery after wildfire in high and low fire severity locations of the CZU Fire using two camera trap grids. The high-severity grid …

Exploring Community Adaptation To Public Safety Power Shutoff Events: Findings From Two Case Studies Of Unincorporated Mountain Communities In Southern California, Ramiro M. Brown

Master's Theses

As aging electrical infrastructure in the US continues to succumb to unyielding weather patterns brought on by climate change, there is an urgency among Investor-Owned Utilities (IOUs) to reduce the likelihood of their equipment sparking a wildfire. Public Safety Power Shutoffs (PSPS) – the intentional de-energization of the electrical grid on high fire weather danger days – have become a staple in IOU Wildfire Mitigation Plans (WMPs) since 2018 as one way to avoid wildfire ignitions via electrical infrastructure. One criticism of PSPS events is that they create their own hazard by cutting off power to thousands – sometimes millions-of …

Win-Win Ecology: Can Mosses Promote Dudleya Germination To Restore California Quarries?, Kate L. Worrell

Master's Theses

Human actions directly damage habitat for native plants; restoration ecology facilitates successful plant re-establishment in these environments. Open-pit mines leave behind steep, rocky, and nutrient-deficient habitats that are some of the most degraded ecosystems on the planet. Dudleya or ‘live-forevers’— a genus of native California succulent plants that contains many rare, threatened, or endangered species — grow on rocky cliffs and may create a successful reclamation-restoration story. However, Dudleya germination is poorly understood. Much of the literature on Dudleya cites a single field report suggesting that bryophytes facilitate germination, but no previous experiments have evaluated this proposal. In this study, …

The Impacts Of Recreational Infrastructure On Mammal Use Of Riparian Zones In Northern California Regional Parks, Emily A. Matthews

Master's Theses

Public lands have been important for the protection of riparian habitats; however, many public lands are also used for recreation, which can reduce mammal habitat use. Understanding how mammals are affected by recreation in riparian areas can help guide management decisions. The goal of this research is to understand the effect of recreation on mammal use of riparian habitats in two popular East Bay Regional Parks, Charles Lee Tilden and Wildcat Canyon, and to map the extent of that impact. Cameras were deployed in the riparian areas of a high, moderate, and low development site (Alvarado, Tilden, and Wildcat Canyon) …

A Trailside Study Of A Coast Redwood Forest Understory Specis, Trillium Ovatum, In The Santa Cruz Mountains, Mary Yan

Master's Theses

To fully understand one of the world’s greatest terrestrial carbon sinks, the coast redwood forest, a co-occurring species may be the key to unique and accessible opportunities to collectively monitor the health of this important habitat. I investigated the relationship between hiking trails and Trillium ovatum within the redwood forests of three California State Parks. Utilizing quadrats across 115 one-meter plots and 58 10-meter transects, T. ovatum occurrence and abundance were recorded and analyzed with factors including proximity to trails, distance from streams, elevation, slope, canopy cover, duff depth, co-occurring understory species, and tree species dominance. Results indicated a higher …

An Assessment Of Anthropogenic Injuries On White Sharks (Carcharodon Carcharias) In Central California, Kaitlyn Yee

Master's Theses

As human activities increasingly impact marine ecosystems, understanding the effects of anthropogenic activity on white sharks is important for their continued conservation. Human-induced injuries are observed in many shark species. Such injuries have been found to have physiological and ecological impacts. Four sites in Central California off the coasts of Aptos, Año Nuevo Island, Southeast Farallon Island, and Point Reyes are all known areas of white shark aggregation with varying levels of human use and protection. Utilizing a vast video database, this study evaluated the effects of natural and non-natural anthropogenic shark injury types across all locations, age classes, and …

The results …

Comparing Shade And Impervious Surface Area With Extreme Heat And Environmental Equity: An Analysis Of The Urban Heat Island Effect In Santa Clara County, California, Jamsheed R. Mistry

Master's Theses

In the modern epoch of the Anthropocene, the rapid rise in urban sprawling has prompted a disproportionate exposure to extreme heat within underserved communities. As the global populace becomes increasingly urbanized, the inevitable formation of urban heat islands is becoming an imminent cause of concern for environmental and social justice. Due to an increase in urbanization, anthropogenic activities have not only increased the energy demand for cooling initiatives but also have increased the intensity of heat-related illnesses, such as heart attacks, dehydration, and respiratory diseases. Additionally, urbanization has yielded an unequal distribution of heat exposure and heat-related illnesses, particularly in …

History Education: Learning History From Community College Students’ Perspectives, Mylinh V. Pham

Dissertations

Given the current political climate of division, the study of history is important now more than ever, but the value of the study of history has been marginalized. This study used student focus groups to understand ways in which history could be taught in such a way that its importance is emphasized through relevance and connection to current social and political issues and through student-centered learning. This study also determined how history could help students evaluate and think critically about historical content. This study drew on the experiences of community college students who have taken a higher education history course …

Nitrous oxide (N2O) is a greenhouse gas and stratospheric ozone-depleting substance with large and growing anthropogenic emissions. Previous studies identified the influx of N2O-depleted air from the stratosphere to partly cause the seasonality in tropospheric N2O (aN2O), but other contributions remain unclear. Here, we combine surface fluxes from eight land and four ocean models from phase 2 of the Nitrogen/N2O Model Intercomparison Project with tropospheric transport modeling to simulate aN2O at eight remote air sampling sites for modern and pre-industrial periods. Models show general agreement on the seasonal phasing of zonal-average N2O fluxes for most sites, but seasonal peak-to-peak amplitudes …

Overcoming Barriers To Improved Decision-Making For Battery Deployment In The Clean Energy Transition, Brian Tarroja, Julie M. Schoenung, Oladele Ogunseitan, Alissa Kendall, Yang Qiu, Timothy Malloy, Jens Peters, J. Mijin Cha, Dustin Mulvaney, Oliver Heidrich, Manuel Baumann

Faculty Research, Scholarly, and Creative Activity

Decarbonization plans depend on the rapid, large-scale deployment of batteries to sufficiently decarbonize the electricity system and on-road transport. This can take many forms, shaped by technology, materials, and supply chain selection, which will have local and global environmental and social impacts. Current knowledge gaps limit the ability of decision-makers to make choices in facilitating battery deployment that minimizes or avoids unintended environmental and social consequences. These gaps include a lack of harmonized, accessible, and up-to-date data on manufacturing and supply chains and shortcomings within sustainability and social impact assessment methods, resulting in uncertainty that limits incorporation of research into …

Habitat Characterization Of American Badgers (Taxidea Taxus) Of Northern California, Mitchell Victoria

Master's Theses

American badgers (Taxidea taxus) are a semi fossorial mammal that lives in grassland and open prairie ecosystems as well as coastal prairies, agricultural fields, deserts, and deforested habitats. Many researchers have published work on badgers, but we still require more information on their ecology. The American badger is a semi fossorial, solitary, predatory mammal of grassland ecosystems. They are classified as mesopredators when compared to larger apex predators such as brown bears, wolves, and pumas. However, when larger carnivores are absent, Badgers become apex predators of their ecosystems. Los Vaqueros Watershed in Brentwood, California, was my study site because badgers …

Assessing The Effectiveness Of Non-Traditional Climate Change Communication Tools In The City Of Santa Cruz, Saara Ranabhat

Master's Theses

Coastal cities face significant challenges from climate-induced coastal hazards. The City of Santa Cruz is a medium-sized municipality in Monterey Bay on California's Central Coast with over $1 billion worth of property and infrastructure at risk to climate-induced coastal hazards by 2100. However, city officials have noticed a lack of representation of climate-vulnerable communities in the development of various climate adaptation plans and policies. In order to remedy this problem, the City is experimenting with various climate change communication tools, such as virtual reality (VR), card games, murals, and comic books, in collaboration with different agencies. But limited understanding exists …

Justice And Equity In Urban Water Allocations And Conservation Solutions: A Case Study Of Non-Traditional Housing Dwellers, Matthew J. Mangoni

Master's Theses

Access to water is a human right. With droughts becoming more frequent and severe, equitable and just access to fresh water is a critical concern for policymakers and regulators. Allocation-based (AB) water rates are used widely to incentivize conservation. Previous authors document benefits of this approach for single family homes (SFH) in urban areas. People living in homeowners’ associations (HOAs) or multi-family homes and renters – commonly grouped as non-traditional housing (NTH) tend to face barriers to understanding or controlling water use and costs. This thesis investigates the equity and effectiveness of 1) AB water rate structuring and 2) a …

Comparitive Analysis Of Time Series Forecasting Using Frequency Informed Dense Neural Networks And Lstm, Avinash Mangalore Suresh

Master's Projects

Time series forecasting influences our lives on a daily basis, being a versatile tool in various application areas like environmental studies, finance, medicine and much more. While there are many established statistical and deep learning approaches to model time series data, each implementation comes with their own set of drawbacks or areas of improvements. Most of the existing deep learning architectures and research have focused on modeling time series data in the time-domain exclusively. However training deep learning models in the time-domain has some drawbacks, mainly due to the inherent temporal dependence of each time-step on the time-steps before it, …

Opening The Black Box: Carbon-Footprint Calculators, Meat Consumption, And The “Wicked Problem” Of Metric Governance, E. Melanie Dupuis, Dustin Mulvaney

Faculty Research, Scholarly, and Creative Activity

Carbon-footprint calculators are widely used as communication and education tools, designed to make people aware of the ways their personal actions contribute to greenhouse-gas emissions. However, they have come under criticism for emphasizing individual behavior versus structural change. We extend this critique to argue that carbon-footprint calculators are a form of “metric governance” that not only disciplines users but also constrains their abilities to engage with the complexities of climate change and social action. We focus on a particularly wicked problem of carbon-metric governance: livestock greenhouse-gas emissions. We show that carbon-footprint calculators black box and fix the complex politics and …

Optimizing Field-Linked Simulations Of Dry Season Uptake And Monsoon Infiltration Within An Aspen-Mixed Conifer Forest, Raymond J. Hess

Master's Theses

Climate models forecast that headwater catchments in the western U.S. will undergo a reduction in snowpack, early season snowmelt, and increases in evapotranspiration. The resulting extended dry season will stress vegetation in mountainous watersheds throughout the Upper Colorado River Basin. We investigate infiltration patterns and root water uptake in response to dry season disturbances within the East River watershed in Colorado. To do this, we collected soil cores, measured matric potential and sap flow, and monitored tree xylem and soil for stable isotopes of water (2H, 18O) in two soil profiles to 90 cm depth (with three Engelmann spruce and …

Lithium And Water: Hydrosocial Impacts Across The Life Cycle Of Energy Storage, James J.A. Blair, Noel Vineyard, Dustin Mulvaney, Alida Cantor, Ali Sharbat, Kate Berry, Elizabeth Bartholomew, Ariana Firebaugh Ornelas

Faculty Research, Scholarly, and Creative Activity

As a key ingredient of batteries for electric vehicles (EVs), lithium plays a significant role in climate change mitigation, but lithium has considerable impacts on water and society across its life cycle. Upstream extraction methods—including open-pit mining, brine evaporation, and novel direct lithium extraction (DLE)—and downstream processes present different impacts on both the quantity and quality of water resources, leading to water depletion and contamination. Regarding upstream extraction, it is critical for a comprehensive assessment of lithium's life cycle to include cumulative impacts related not only to freshwater, but also mineralized or saline groundwater, also known as brine. Legal frameworks …
