Urban Agroecology For Food Sovereignty And Biodiversity: Are Urban Community Farms Or Gardens More Effective?, Heidi L. Giancola

Master's Theses

Industrial agriculture is accurately criticized for eliminating biodiversity and destroying food sovereignty. Urban agroecosystems, usually individual plots in community gardens, are promoted to restore ecological services and equity to food systems. Recently, collectively tended urban community farms have developed, with explicit social justice goals. This study directly contrasts the effectiveness of the urban community farm and garden models. Spatial analysis is used to confirm that community farms enhance geographic access for healthy food priority areas compared to gardens in the San Francisco bay area. An online survey of farm staff and gardeners from Marin to Santa Clara County resulted in …

Changes In Allochronic Breeding Populations Of Pink Salmon (Oncorhynchus Gorbuscha) Of Prince William Sound, Alaska, Claire Dormody

Master's Theses

Prince William Sound, Alaska is home to one of the largest pink salmon (Oncorhynchus gorbuscha) fisheries in the world. Salmon populations there have been fished commercially for over a century, and the State’s documentation of commercial fishing provides a valuable dataset in order to examine abundance trends of species in this region. For this thesis research, I analyzed the fluctuations in abundance and isolated even year and odd year breeding populations of pink salmon to assess whether there is a numerical discrepancy between pink salmon that spawn in odd years and the population that spawns in even years. Analysis of …

Distribution And Habitat Use Of The Santa Clara County Population Of Red-Bellied Newts (Taricha Rivularis), Joie De Leon

Master's Theses

Anthropogenically-induced habitat loss and degradation have increased extinction rates in amphibians worldwide, yet little is known about many remaining populations. A disjunct population of red-bellied newt (Taricha rivularis), an endemic California species, was discovered 130 km south of its previously known range. Here I document the range and breeding phenology of this population and contrast its mesohabitat use with that of other sympatric newts. Surveys across two years suggest that the southern population of T. rivularis is confined to a 1 km segment of Stevens Creek, and the population follows an early-March to late-April migratory breeding pattern, similar to one …

The Relationship Between Different Forms Of Exercise And Adhd Symptomatology, Matthew A. Reynolds

Master's Theses

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder associated with executive function deficits as well as negative life outcomes in both childhood and adulthood. Current treatments to reduce symptoms of ADHD include stimulant medications that act as catecholamine agonists. These medications often cause undesirable side effects, to which end better understanding the effects of non- pharmacological treatments on symptoms of ADHD is critical. Research conducted in children suggests that exercise may be an effective tool for symptom reduction. However, the relationship between exercise and ADHD symptoms remains unclear for adults. The aim of this study was to address this …

Humpback Whale, Megaptera Novaeangliae, Feeding Dynamics From The Perspective Of The Individual: Insights From Demography, Life History, And Bio-Logging, Jennifer Tackaberry

Master's Theses

Studies of fission-fusion societies provide a framework in which to compare the feeding dynamics across demographics, unrestrained by stable associations or relatedness. This study used bio-logger data and surface observations combined with long-term population data from the Gulf of Maine humpback whale, Megaptera novaeangliae, population to investigate the influence of demographics on feeding methods, and time spent feeding, and to determine if a coordinated feeding method, kick-feeding, was a cooperative behavior. The results suggest that demographics did influence the feeding method used and highlighted the need to determine how energetic needs change across the feeding season. Adult females did not …

Examination Of Flow Patterns During Droplet Formation And In Venous Valve Mimic Using Μ-Piv, Vignesha Vijayananda

Master's Theses

In this work, particle image velocimetry (PIV) was used for fluid flow visualization in both continuous and segmented-flow microfluidics. Droplet microfluidics is known for its precise and consistent volume dispersion between microliters and picoliters in volume for application ranging from molecular synthesis, drug discover, and diagnostics. But the influence of junction geometry on the process of drop formation has not been investigated. In this study, µ-PIV was used to study the internal flow during the drop formation process in flow-focus microfluidic device with and without constriction. It was found that in case of flow-focus with constriction, the shear force on …

Epiphyte-Host Dynamics Between Pyropia And Nereocystis In Central California, Daniel Joseph Gossard

Master's Theses

Macroalgal epiphytism is widespread, but many unique epiphyte-host interactions remain poorly understood. Pyropia nereocystis is an annual northeastern Pacific species that has evolved to primarily epiphytize the annual kelp Nereocystis luetkeana. I examined three aspects of Pyropia-Nereocystis epiphyte-host dynamics in the southern extent of the host’s range: (1) temporal variation in epiphtyte presence; (2) growth of gametophyte and sporophyte (conchocelis) stages using transplantation experiments; and (3) effects of epiphyte depth and host characteristics on the recruitment and biomass of the epiphyte. Pyropia exhibited a shift in presence on Nereocystis that differed interannually as a function of Nereocystis density and Nereocystis …

Versatile Disubstituted Imidazole Ligands For Suzuki-Miyaura Coupling Under Mild Conditions, Daniel Parker

Master's Theses

Synthesis of small molecules for medicine, agriculture, or research often requires the formation of carbon-carbon and carbon-heteroatoms bonds, and palladium catalyzed reactions have emerged as a potent technique for these cross-coupling reactions. To address increasing catalysts demands, our research has focused on the development of a versatile catalyst platform bearing imidazole pendants as ligands to support cross-coupling reactions under mild conditions, an area of current interest. A series of bridged imidazole ligands was synthesized using a modular approach and characterized by 1H NMR spectroscopy.

Graphical Models In Reconstructability Analysis And Bayesian Networks, Marcus Harris, Martin Zwick

Complex Systems Faculty Publications and Presentations

Reconstructability Analysis (RA) and Bayesian Networks (BN) are both probabilistic graphical modeling methodologies used in machine learning and artificial intelligence. There are RA models that are statistically equivalent to BN models and there are also models unique to RA and models unique to BN. The primary goal of this paper is to unify these two methodologies via a lattice of structures that offers an expanded set of models to represent complex systems more accurately or more simply. The conceptualization of this lattice also offers a framework for additional innovations beyond what is presented here. Specifically, this paper integrates RA and …

Efficient Polyhydroxyalkanoate Production By Rhodopseudomonas Palustris From Lignocellulosic Biomass, Brandi Brown

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Polyhydroxyalkanoates (PHAs) are biopolymers produced by bacteria with the potential to replace conventional plastics. However, the relatively high production costs of PHAs are keeping them from market acceptance, with approximately half of the production costs derived from the feedstock. Thus, engineering a microbe for PHA production from cheaper and renewable carbon sources is necessary to promote the valorization of PHAs. Lignocellulosic biomass is considered to be one of the most economic carbon sources in the world, and is thus an attractive candidate for cheaper production of bioplastics. Rhodopseudomonas palustris CGA009 is a metabolically robust bacterium capable of catabolizing lignin breakdown …

Accepting Evolution Entails Kufr? A Critical Appraisal Of Nuh Ha Mim Keller’S Fatwa, Shoaib Ahmed Malik, Elvira Kulieva, Ayub Ayub

All Works

Muslim scholars who oppose the compatibility of Islam and evolution usually advance three kinds of arguments: scientific, metaphysic, and hermeneutic. This paper will examine the position of Nuh Ha Mim Keller, a prominent Sunni scholar who employ these three lines of arguments and proposes that believing in human evolution entails kufr. In this article we will critically analyze Keller’s understanding of the science of evolution in which he claims that the theory of evolution is not robust. We argue that through the consilience of induction, evolution is the best explanation for the biological origins and diversity. We also argue that …

Fire And Rodent Consumer Effects On Plant Community Assembly And Invasion In North American Deserts, Rebekah L. Stanton

Theses and Dissertations

This dissertation explores the differential effects of fires and rodent communities on native and invasive desert plant communities. Chapter one examines the impacts of fire and repeat fires on fuel loads in two different Utah desert sites, one in the cool Great Basin Desert and one in the hyper-arid Mojave Desert, over the course of four years. We found that both desert sites responded with varying intensities to a single burn, but the effects of a reburn were not as pronounced. We also found that our Great Basin Desert site had a stronger response to fire than our Mojave Desert …

Pre-Columbian Cultivation Of Agave Species Through Rock Mulching: Potential For Modern Applications, Hector Genaro Ortiz Cano

Theses and Dissertations

As global temperatures rise, cultivation of C3 and C4 crops in arid and semi-arid regions will face major challenges in producing biomass for billions of people. Conventional agricultural techniques that require copious irrigation will need to be complemented with dryland-farming techniques and drought-tolerant crops, such as those from the Agave genus, which use CAM photosynthesis. In the past and present, humans from arid and semi-arid regions of America have maintained a symbiotic relationship using and cultivating Agave (Agavoideae, Asparagaceae). In pre-Columbian times, Native Americans from arid regions relied on Agave cultivation as a subsistence crop to produce food, medicine, and …

Structural Basis For +1 Ribosomal Frameshifting During Ef-G-Catalyzed Translocation., Gabriel Demo, Howard Gamper, Anna B. Loveland, Isao Masuda, Christine E. Carbone, Egor Svidritskiy, Ya-Ming Hou, Andrei A. Korostelev

Department of Biochemistry and Molecular Biology Faculty Papers

Frameshifting of mRNA during translation provides a strategy to expand the coding repertoire of cells and viruses. How and where in the elongation cycle +1-frameshifting occurs remains poorly understood. We describe seven ~3.5-Å-resolution cryo-EM structures of 70S ribosome complexes, allowing visualization of elongation and translocation by the GTPase elongation factor G (EF-G). Four structures with a + 1-frameshifting-prone mRNA reveal that frameshifting takes place during translocation of tRNA and mRNA. Prior to EF-G binding, the pre-translocation complex features an in-frame tRNA-mRNA pairing in the A site. In the partially translocated structure with EF-G•GDPCP, the tRNA shifts to the +1-frame near …

The Cgas–Sting Pathway In Diabetic Retinopathy And Age-Related Macular Degeneration, Shannon Erhardt, Mingjie Zheng, Xiaolei Zhao, Tram P Le, Tina O Findley, Jun Wang

Faculty, Staff and Student Publications

The neural crest (NC) is a multipotent and temporarily migratory cell population stemming from the dorsal neural tube during vertebrate embryogenesis. Cardiac neural crest cells (NCCs), a specified subpopulation of the NC, are vital for normal cardiovascular development, as they significantly contribute to the pharyngeal arch arteries, the developing cardiac outflow tract (OFT), cardiac valves, and interventricular septum. Various signaling pathways are shown to orchestrate the proper migration, compaction, and differentiation of cardiac NCCs during cardiovascular development. Any loss or dysregulation of signaling pathways in cardiac NCCs can lead to abnormal cardiovascular development during embryogenesis, resulting in abnormalities categorized as …
