Alameda Song Sparrow Habitat Use Of Salt Pond Restoration Sites In South San Francisco Bay, Bradley A. Speno Aug 2025

Alameda Song Sparrow Habitat Use Of Salt Pond Restoration Sites In South San Francisco Bay, Bradley A. Speno

Master's Theses

Restoration is acknowledged worldwide as a conservation need to return ecosystem functions. However, projects require monitoring to track system changes and assess restoration progress. In the San Francisco Bay, several large restoration projects are implementing plans to return salt-producing ponds to the historical ecosystem, tidal salt marsh. The Alameda song sparrow (Melospiza melodia pusillula), a California species of special concern, has been documented to use restored and historic marshes, but their use of restored salt ponds is not fully understood. The birds’ use of restored marshes may be a useful measure of restoration progress. This research investigated the relationships comparing …


California Utility-Scale Solar Energy Land Use Impacts On Species And Ecosystems, Ingrid Salazar Aug 2025

California Utility-Scale Solar Energy Land Use Impacts On Species And Ecosystems, Ingrid Salazar

Master's Theses

Utility-scale solar energy (USSE), defined as projects of at least 1 megawatt, is rapidly expanding in California, which generated 37.5% of its electricity from renewables in 2023, with 24% coming from solar. While USSE supports decarbonization, it can also cause environmental harm, including biodiversity loss, habitat fragmentation, and land conversion. This study uses ArcGIS Pro 3.4.0 and public environmental data to analyze the spatial distribution of USSE projects, land use changes from 2013 to 2023, and occurrences of at-risk species across California’s bioregions. USSE development is heavily concentrated in the Mojave Desert, San Joaquin Valley, and Colorado Desert, which are …


Riparian Restoration Increases Soil Microbial Biomass In Marin County Rangelands, But Soil Carbon Stock Is Less Responsive, Sherilyn Kathryn Reinhart Aug 2025

Riparian Restoration Increases Soil Microbial Biomass In Marin County Rangelands, But Soil Carbon Stock Is Less Responsive, Sherilyn Kathryn Reinhart

Master's Theses

Land use change has caused the degradation of 70% of the Earth’s soils, directly altering soil microbial communities and carbon cycling. Interest in carbon farming practices is growing, but studies that document the nuances of soil carbon flux in specific bioregions are still too few. In this study, I examined how one practice, riparian restoration, alters soil carbon stock and microbial community structure over time. Using a paired sampling time series design, I collected soil samples from twelve riparian forests and adjacent rangelands near Marin County, California. Young and mature sites ranged from five to 29 years since restoration, and …

High Abundances Of Crustose Coralline Algae Inside Cryptic Coral Habitats Linked To Coral Reef Functioning, Anna Rothstein, Orion S. Mccarthy, Sophie Luu, Emily L.A. Kelly, Philip Heller, Stuart Sandin, Jennifer E. Smith, Maya S. Devries

Faculty Research, Scholarly, and Creative Activity

Cryptic habitats on coral reefs consist of crevices, tunnels, and holes that are estimated to comprise 30%–75% of the total reef surface area. These large habitats are vastly understudied because they are often difficult to access. Crustose coralline algae (CCA) are thought to perform important ecological functions, including calcium accretion, both inside cryptic habitats and on the exposed (top) reef. Using GoPro cameras, we surveyed 250 coral crevices from 13 reefs on West Maui, Hawai‘i. We compared relative CCA cover between crevice microhabitats and the well-studied top-reef and identified abiotic and biotic factors that correlated with CCA abundance. We found …

Faculty Research, Scholarly, and Creative Activity

Objectives: In the San Francisco Bay Area, Late Holocene resource intensification models predict an increase in diet breadth and a reduction in foraging efficiency associated with an increase in population, sedentism, and territoriality among fisher-hunter-gatherer populations. Here we compare bone stable carbon (δ13C) and nitrogen (δ15N) isotope values of sites along the eastern bay shore to interpret how ecogeographical partitioning of resources by latitude and distance from the bay reflects differential access and control of resources. Materials and Methods: With the support of, and in collaboration with, the Muwekma Ohlone Tribe of the San Francisco Bay …


Learning Structure With Multivariate Information Bottleneck And Exploration Of New Methods In Sequential Decision Making, Volodymyr Makarenko Aug 2025

Learning Structure With Multivariate Information Bottleneck And Exploration Of New Methods In Sequential Decision Making, Volodymyr Makarenko

Master's Theses

Research in useful information extraction has been motivated by the increasing demand to extract insights from unstructured data, and by the need to store and transmit great volumes of information, often originating in unstructured data such as videos. Research in rate distortion and information bottleneck paved the path for understanding and guiding the design of lossy encoders, capable of extracting relevant information. Independently, research in deep representation learning has enabled numerous applications for unstructured high-dimensional data such as images. However, the interpretability of the deep learning methods remained limited. Several desired properties of learned representations have been suggested, including disentanglement. …

Isolation, Identification, And Antitumor Activities Of Glucosinolates And Isothiocyanates In Chinese Cabbage Seeds, Bei Zhou, Ying Liu, Xi Feng, Qian Liu, Salam A. Ibrahim, Wen Huang

Faculty Research, Scholarly, and Creative Activity

Isothiocyanates (ITCs), which are derivatives of glucosinolates (GSLs) from Brassica plants, have been investigated as anticancer agents. An extensively studied anticancer ITC is sulforaphane, which is found in low amounts in Chinese cabbage. We aim to investigate the types and content of GSLs (precursors of ITCs with anticancer activity) in Chinese cabbage seeds. GSLs from Chinese cabbage seeds were isolated and purified using acidic Al2O3 column chromatography and preparative HPLC. GSL and ITC profiles were further identified using UHPLC-Q-TOF-MS. The antitumor activities of ITC (produced by exogenous enzymatic hydrolysis of GSLs) were evaluated in vitro. Seventeen GSLs and seven ITCs …


Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi Aug 2025

Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi

Comparative Philosophy

This article offers a comparative philosophical analysis of Confucian liang-zhi (innate moral knowledge) and Islamic fitra(primordial nature), focusing on their accounts of innate morality and moral epistemology. Drawing on classical Confucian sources—especially the praxis-oriented interpretation of Wang Yangming—and foundational Islamic texts and commentary, the study demonstrates that both traditions posit an inborn moral faculty grounding ethical universality and responsibility. Wang Yangming’s liang-zhi is conceived as an innate moral principle that, under the imperative of zhi (to actualize or extend), is continually activated through moral practice. In parallel, fitra is understood as a God-given orientation to truth, cultivated and safeguarded through …


Reassessing The Deontological Undercurrents In Mo Zi’S Ethical Thought, Nuno Miranda Aug 2025

Reassessing The Deontological Undercurrents In Mo Zi’S Ethical Thought, Nuno Miranda

Comparative Philosophy

This article reexamines Mo Zi’s ethical philosophy, challenging the dominant interpretation of Mohism as a purely consequentialist or proto-utilitarian system. While Mo Zi’s emphasis on social utility—such as material welfare, population growth, and aversion to warfare—aligns with outcome-oriented reasoning, I argue that his invocation of the will of Heaven introduces a deontological dimension. Heaven’s will serves not merely as a heuristic for maximizing benefits but as an absolute moral standard, demanding adherence to duties like universal love and non-aggression, irrespective of immediate practical gains. Through a close reading of the Mo-Zi corpus, this study reveals a hybrid ethical framework that …


It Shucks To Be Inbred: Effects Of Small Population Sizes On Genomic Diversity Of Hatchery Reared Olympia Oysters (Ostrea Lurida), Anna S. Heasley Aug 2025

It Shucks To Be Inbred: Effects Of Small Population Sizes On Genomic Diversity Of Hatchery Reared Olympia Oysters (Ostrea Lurida), Anna S. Heasley

Master's Theses

Olympia oysters (Ostrea lurida), critical members of estuarine ecosystems along the California Current Ecosystem (CCE), have faced significant population declines due to historical overfishing and habitat deterioration. Today, managers from multiple estuaries across the CCE are focusing on conservation aquaculture breeding efforts to aid in restoration; however, the genetic implications of these efforts remain unexplored. As with other Ostrea spp, Olympia oysters have a viviparous reproductive strategy that creates unique challenges for aquaculture-mediated restoration. This study evaluates the genetic impact of current captive breeding practices on Olympia oyster cohorts produced in three California estuaries: Elkhorn Slough (EHS), Morro Bay (MB), …


Acoustic Presence Of Humpback Whales (Megaptera Novaeangliae) In U.S. West Coast National Marine Sanctuaries, John C. Barkowski Aug 2025

Acoustic Presence Of Humpback Whales (Megaptera Novaeangliae) In U.S. West Coast National Marine Sanctuaries, John C. Barkowski

Master's Theses

Humpback whales are one of many species of marine mammal that utilize sound in multiple aspects of their lives in the oceans. By collecting acoustic data from multiple areas across the habitat of these animals, we can investigate spatiotemporal patterns in their sound production to better understand their life history strategy. This study uses three years of passive acoustic data collected concurrently from three U.S. West Coast National Marine Sanctuaries to look for spatiotemporal patterns in humpback whale song and non-song vocalizations. Additionally, this study investigated correlations between upwelling conditions and the onset of song to explore links between the …


Working Memory In Major Depressive Disorder: A Meta-Analysis Of Structural And Functional Brain Differences, Eunji Back Aug 2025

Working Memory In Major Depressive Disorder: A Meta-Analysis Of Structural And Functional Brain Differences, Eunji Back

Master's Theses

Major depressive disorder (MDD) is one of the most prevalent mental health disorders in the US and is characterized by depressed mood and loss of interest. Many MDD patients also experience difficulties with executive function, including working memory. Neuroimaging studies reveal structural and functional brain differences between MDD patients and healthy controls that may underlie these working memory difficulties, but findings have been mixed. A quantitative synthesis of neuroimaging data through a meta-analytic approach offers a promising avenue to identify commonalities across studies. We conducted separate meta?analyses of structural and functional magnetic resonance imaging (MRI) data, with the latter focused …

The decomposition of oceanic flow into its geostrophically balanced and unbalanced motions carries theoretical and practical significance for the oceanographic community. These two motions have distinct dynamical characteristics and affect the transport of tracers differently from one another. The launch of the Surface Water and Ocean Topography (SWOT) satellite provides a prime opportunity to diagnose the surface balanced and unbalanced motions on a global scale at an unprecedented spatial resolution. Here, we apply dynamic-mode decomposition (DMD), a linear-algebraic data-driven method, to tidally-forced idealized and realistic numerical simulations at submesoscale-permitting resolution and one-day-repeat SWOT observations of sea-surface height (SSH) in the …

Climate Drives Genetic Diversity Loss In American Pika (Ochotona Princeps) Populations In The Great Basin, Emily N. Kulig, Jane Van Gunst, Michael J. Hernandez, Yvonne Luong, Monica Villaseñor, Rachel S. Crowhurst, Clinton W. Epps, Jessica A.Castillo Vardaro

Faculty Research, Scholarly, and Creative Activity

American pikas (Ochotona princeps) are small, thermally sensitive mammals that primarily live in montane and alpine environments. The Sierra Nevada lineage (O. p. schisticeps) has experienced numerous local extinctions, most of which occurred in hotter, drier regions such as the Great Basin. Few genetic studies have assessed these at-risk populations. This study aims to fill that gap by conducting fine-scale genetic analyses on populations in low-elevation Great Basin habitat in northwestern Nevada. Specifically, we: (i) quantified genetic diversity and structure among populations within O. p schisticeps, with particular focus on northwestern Nevada; and (ii) assessed the influence of primary productivity …


The Influence Of Rhodolith Algae On Life History Of The Painted Urchin, Lytechinus Pictus, Celine X. De Jong Jul 2025

The Influence Of Rhodolith Algae On Life History Of The Painted Urchin, Lytechinus Pictus, Celine X. De Jong

Master's Theses

Rhodolith beds are globally distributed hotspots of diversity and productivity and serve as nursery habitats for some marine invertebrates. Poorly understood is whether rhodolith beds are nurseries because invertebrate larvae actively select them for settlement or migrate to them at later life stages. We studied the nursery role of rhodolith beds for the painted urchin, Lytechinus pictus at Santa Catalina Island, CA, USA. Subtidal surveys showed that in areas with greater live rhodolith cover, urchin density increased as well as mean urchin size. In caged substrate choice experiments, urchins selected rhodolith substrate relative to carbonate sand, supporting the notion that …

Experienced Latinx Urban Gardeners In San Jose, Ca, Offer Strategies For Climate Justice And Resilience, Claudia S. Damiani Fontana

Master's Theses

Low-income and underinvested communities will be disproportionately affected by climate change due to limited resources, inadequate infrastructure, and insufficient support systems. Urban gardeners are responding to the need to adapt to new climate conditions while sustaining their food sources and cultural practices. Many have adapted thanks to local interventions led by the government and non-profit agencies. For this study, I partnered with La Mesa Verde (LMV), a gardening and food justice program that works with low-income Latinx families in San José, and I documented the contributions of experienced Latinx gardeners, especially those with agricultural backgrounds, to climate-resilient gardening in San …

How Effective Are Engineered And Non-Engineered Riparian Forest Restoration Projects In Providing Salmonid-Quality Habitat In The San Francisco Bay Area?, Alexander Ivanov

Master's Theses

Streams and their riparian zones in the San Francisco Bay Area have been degraded, severely harming salmonid populations in the region. Ecological restoration is a common approach to return stream function. Such restoration projects vary widely in intensity, from low-impact vegetation removal/planting to highly engineered projects involving structures and grading. This research investigated the effectiveness of streams restored using engineered versus non-engineered solutions in supporting salmonid habitat viability in San Francisco Bay Area streams. Fourteen streams, seven from each of the two types of restoration, were sampled in the wet and dry season in 2024, three times each season. Data …


Quantization On Graph Neural Networks For Image Classification, Rithik Reddy Katpally Jul 2025

Quantization On Graph Neural Networks For Image Classification, Rithik Reddy Katpally

Master's Theses

Quantization has become a key approach for reducing storage and computational demands of deep neural networks while maintaining high accuracy. Although 8-bit quantization is well-established for convolutional architectures such as ResNet50 and MobileNetV2, its application to graph-based vision models remains underexplored. In this work, we extend quantization-aware training to Vision Graph Neural Networks (ViGs) and conduct comparisons with quantized CNNs on the CIFAR-100 dataset. To ensure parity, all models have same training hyperparameters such as learning rate, batch size, optimizer, number of epochs. We used numerous techniques to preserve performance for low-bit precision. First, Pauta Quantization clips activation outliers based …


Abalone And Seaweed Co-Culture: Growth And Shell Biomineralization Of An Iconic California Gastropod, Noah R. Kolander Jul 2025

Abalone And Seaweed Co-Culture: Growth And Shell Biomineralization Of An Iconic California Gastropod, Noah R. Kolander

Master's Theses

Climate change threatens shellfish aquaculture worldwide, with ocean acidification (OA) accelerating shell dissolution and reducing calcification, hindering growth. This study addressed the negative impacts of OA on juvenile red abalone (Haliotis rufescens), a life stage that is particularly susceptible to climate stressors, and the ability of the red seaweed, dulse (Devaleraea mollis), to mitigate these effects. I tested the hypothesis that Integrated Multi-Trophic Aquaculture (IMTA), with abalone and seaweed grown in co-culture, can raise seawater pH through photosynthesis to yield more favorable conditions for abalone growth and shell construction. A 5-month experiment was conducted to determine the benefits of IMTA …


Investigating The Complexity Of Language Acquisition For Linguistically Diverse Children, Krittin Srisajjakul Jul 2025

Investigating The Complexity Of Language Acquisition For Linguistically Diverse Children, Krittin Srisajjakul

Master's Theses

Understanding the natural productions of children's early expressive language development is important to support their development. These natural productions may also be especially complex in children with diverse linguistic backgrounds. A challenge for clinicians is how to assess these natural productions for children’s early expressive language milestones. For example, what does it mean for children to say the same word in two languages and refer to the same concept (e.g., “water” and “agua”)? Or refer to two different concepts, (e.g., “water” and “leche” (milk))? By understanding how children’s expressive language connects to conceptual understanding, clinicians can better support language learning. …

Introduction: Shiftwork contributes to poor sleep and circadian disruption, leading to adverse health outcomes. With a high number of young adults (18–25 years) engaging in shiftwork, exposure to these health challenges can occur from early adulthood. Therefore, there is an urgent need for age- and career-stage-appropriate resources focused on sleep health to mitigate poor health outcomes as early as possible. Given the absence of such resources, this study aimed to develop tailored, evidence-based sleep health materials for young shiftworkers. Methods: A participatory approach was employed, with co-designers (n = 48) attending 1–2 online workshops to develop sleep health resources for …


Santa, Socials, And Secrets: Hard Cases For Epistemic Rights, Étienne Brown, Rebecca Chan Jun 2025

Santa, Socials, And Secrets: Hard Cases For Epistemic Rights, Étienne Brown, Rebecca Chan

Faculty Research, Scholarly, and Creative Activity

In The Right to Know, Lani Watson forcefully argues in favor of recognizing epistemic rights to all humans. In this paper, we apply Watson’s framework to three hard cases. First, we consider interpersonal relationships and suggest that there is room to explore how epistemic rights bear on, e.g., whether parents can permissibly lie to or mislead their children by asserting the existence of Santa Claus. Second, we turn to social media platforms and contend that Watson’s framework is compatible with contrasting moderation policies and transparency requirements. Third, we examine a foundational case of legal ethics—the buried bodies case—which raises the …

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of threatened species will be achieved. We assembled a multi-taxa tracking dataset (11 million geopositions from 15,845 tracked individuals across 121 species) to provide a global assessment of space use of highly mobile marine megafauna, showing that 63% of the area that they cover is used 80% of the time as important migratory corridors or residence areas. The GBF 30% threshold (Target 3) will be insufficient for marine megafauna’s effective conservation, leaving important areas …

An excipient present in commercial formulations of fumagillin (an antibiotic used in apiculture for the control of Nosema disease) toxic dicyclohexylamine is found in beeswax samples. There is a need for a reliable analytical method without the use of MS for analysis of this compound. A reversed-phase gradient method was developed for the analysis using a simple extraction procedure followed by low temperature elimination of interfering compounds. Since dicyclohexylamine is lacking a chromophore, an evaporative light scatter detector was used in this analysis. Several challenges of quantitative analysis using an evaporative light scatter detector were addressed. The reported method was …
