“It’S Essential We Learn How To Grow For Ourselves”: The Legacies Of Black Gardening In Racialized Food Systems., Funmi Odumosu

USF Tampa Graduate Theses and Dissertations

In this thesis, I aim to investigate the impact of food racism on Black communities, with a specific focus on the importance of gardening in combatting food apartheid and fostering holistic connections to nature and community in school-aged children. Inequitable access to major retail supermarkets and unequal distribution of healthy food options are intentionally occurring patterns in the food spaces of predominately Black communities. These food system inequities exacerbate a lack of consumption and potential consequences on the health and well-being of children of color particularly during critical physical and cognitive developmental periods.

Many solutions to these inequities entail implementing …

Assessment And Prioritization Of Contaminants Of Concern Along Florida's Coral Reef, Ellen Regina E. Skelton

All HCAS Student Capstones, Theses, and Dissertations

Florida’s Coral Reef (FCR) is the third largest barrier reef in the world and faces significant stress from localized land, water, and air-based sources of pollution. Numerous chemical contaminants have been found in waters surrounding reefs and within corals, including pesticides, hydrocarbons, personal care products, pharmaceuticals, and trace metals. However, for most current and emergent environmental contaminants, little to no consistent information exists regarding environmental concentrations or toxicological effects on corals. Assessment of the levels of contaminants in coral reef environments is needed to conduct risk assessments to guide management, restoration, and recovery strategies, and the coral reef resource management …

Are Biobased Microfibers Less Harmful Than Conventional Plastic Microfibers: Evidence From Earthworms, W. Courtene-Jones, F. De Falco, F. Burgevin, R. D. Handy, R. C. Thompson

School of Geography, Earth and Environmental Sciences

Biobased plastics are sometimes promoted as “environmentally friendly” compared to their conventional petrochemical-based counterparts, but their ecotoxicity is only partially understood. Biobased fibers are widely used in clothing and wet wipes and can accumulate in soils through the application of biosolid fertilizers. This study examined the lethal thresholds and sublethal toxicity of chemically characterized, additive-free, biobased (viscose and lyocell) compared to petrochemical-based (polyester) fibers on the key ecosystem engineer, Esenia fetida. Viscose and lyocell had LC₂₀ values of 14.00 and 22.66 mg·L^-1, respectively, and no observed effect concentrations (NOEC) of 0-2.8 mg·L^-1 (72 h, OECD TG207 …

Extracting, processing, and delivering energy requires energy itself, which reduces the net energy available to society and yields considerable socioeconomic implications. Yet, most mitigation pathways and transition models overlook net energy feedbacks, specifically related to the decline in the quality of fossil fuel deposits, as well as energy requirements of the energy transition. Here, we summarize our position across 8 key points that converge to form a prevailing understanding regarding EROI (Energy Return on Investment), identify areas of investigation for the Net Energy Analysis community, discuss the consequences of net energy in the context of the energy transition, and underline …

Beyond Direct Education And Facilitation: Revisiting The Role Of Extension In Community & Regional Food Systems Development, Catie M. Demets, Lindsey Day Farnsworth

Journal of Extension

The fundamental issues that community and regional food systems aim to address are inherently systems problems, yet many Extension programs continue to focus food system development efforts on activities and actors that directly support the food value chain. While important, the impact of these interventions is limited. Drawing from interviews with directors of four of the nation’s leading Community and Regional Food Systems Extension programs, this article makes a case for rethinking Extension’s role in community and regional food systems development in relationship to key leverage points through a typology of Extension roles and corresponding examples.

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 …
