The existing educational system is failing to provide adequate environmental education to future generations so that they will have the knowledge, skills, and capability to address the environmental concerns that society is facing. The system must encompass environmental education through adoption of an eco-pedagogical system that either contributes to traditional education or is utilized on its own. The eco-pedagogical system produces education from a social and ecological point of view. As a result of the approach, students would develop and form a connection to nature as well as environmental hope. Each of these components will contribute to the student’s motivation, pathway thinking, agency thinking, and social trust. Leading to the development of the student's aptitude and capability to establish a goal and a plan to achieve it, as well as the identification of potential barriers and strategies for overcoming them. Ultimately, environmental education will equip future generations with the knowledge and skills necessary to create a social system that is capable of sustaining life while also caring for the environment and addressing environmental concerns produced by anthropocentric consequences.

Northwest Arkansas has a complex relationship with Indigeneity due to the erasure experience by the original inhabitants of the lands, and the presences of newly immigrated Indigenous groups such as the Marshallese people from the Republic of the Marshall Islands. Today, the Indigenous identity that is most commonly present within the Northwest Arkansas community are the Marshallese people. The reason as to why the original inhabitants of modern-day Northwest Arkansas are not the most prominently represented Indigenous group, is because of severe erasure, genocide, and systematic racism experienced by these people. This thesis will be investigating the Indigenous identities of Northwest Arkansas, which will include information on the first peoples and the modern-day presence of the Marshallese people. This thesis will particularly be focusing on the ways in which the legacy of colonialism and climate change have linked these groups in their displacement. Despite the differing time periods, the interconnectedness between these Indigenous populations’ experiences with colonialism and colonialist systems further demonstrates the threat that Indigenous populations still face today of erasure and continual oppression. Through both populations’ mutual experience with displacement and diaspora, this thesis will investigate how food can act as an essential connector between Indigenous individuals and their culture, as well as how food can be a form of reparations, healing, and future progress.

In the realm of environmental engineering, the compound N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), has recently emerged as an environmental concern. 6PPD serves as a tire additive to prolong the lifespan of rubber but can transform into a more toxic derivative, N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone (6PPD-quinone), when exposed to ground-level ozone. Initially, my research sought to investigate the biodegradation of 6PPD and 6PPD-quinone using microbial cultures. However, unexpected challenges arising from limited solubility and potential toxicity to microorganisms led to a shift in research objectives. The study then refocused on developing methods for detecting and quantifying 6PPD and 6PPD-quinone. The scarcity of literature available on the environmental fate and transport of these compounds underscores the pressing need for further research to gain a comprehensive understanding of the behavior of these chemicals. Consequently, the development of effective detection strategies will enable the development of effective remediation strategies to safeguard aquatic ecosystems.

Phoenix, Arizona is a city characterized by intense urban sprawl: low-density, spread out, and disconnected development. Within the Phoenix Metropolitan Area comes a new development, Culdesac, that creates car-free living geared towards alternate transit methods. This new neighborhood offers a more sustainable urban form that contrasts Phoenix and has potential to increase walkability in the city. After examining case studies of Vauban, Germany; Masdar City, Abu Dhabi; and Fruitvale, California as examples of sustainable development with a focus on alternate transit, this paper compares these examples to the future of Culdesac. A list of principles of walkability including public participation, scale, creativity, adherence to principles, government cooperation, and transportation help to guide this comparison and determine whether Culdesac is a possible method to increase sustainable urban form in the Phoenix Metropolitan Area.

Influenza virus A (IVA) poses a serious threat to human health, killing over 25,000 Americans in the 2022 flu season alone. In the past 10 years, vaccine efficacy has varied significantly, ranging from 20-60% each season. Because IVA is subject to high antigenic shift and strain cocirculation, more effective IVA vaccines are needed to reduce the incidence of disease. Herein we report the production of a recombinant immune complex (RIC) vaccine “4xM2e” in Nicotiana benthamiana plants using agroinfiltration for use as a potential universal IVA vaccine candidate. RICs fuse antigen to the C-terminus of an immunoglobulin heavy chain with an epitope tag cognate to the antibody, promoting immune complex formation to increase immunogenicity. IVA matrix protein 2 ectodomain (M2e) is selected to serve as vaccine antigen for its high sequence conservation, as only a small number of minor mutations have occurred since its discovery in 1981 in the human sequence. However, there is some divergence in zoonotic IVA strains, and to account for this, we designed a combination of human consensus, swine, and avian M2e variants, 4xM2e. This was fused to the C terminus of the RIC platform to improve M2e immunogenicity and IVA strain coverage. The 4xM2e RIC was produced in N. benthamiana and verified with SDS-PAGE and Western blot assays, along with an analysis of complex formation and the potential for complement activation via complement C1q ELISA. With this work, we demonstrate the potential of RICs and plant-expression systems to generate universal IVA vaccine candidates.

Since 800 CE— long before the creation of the National Park Service (NPS) in 1905 — the Havasupai Tribe has depended on the natural resources and diverse ecosystem of the Grand Canyon. A deeper examination of how the national park came to fruition however demonstrates an often negated and harrowing history of land theft, forced assimilation via reservation systems, and genocide. Political ecology is a way of considering how power dynamics, resource management, and society intersect. In the United States, this approach exposes the ways that anti-Indigenous legislation originating in the Department of the Interior has functioned both as a driver of ecosystem degradation and structural barricades to Native American self-determination. In order to achieve a just and sustainable future for all, it is necessary to dismantle hegemonic discourses regarding Indigenous communities.

In urban planning and design, creating emotional bonds, known as place identity, between people and their surroundings is paramount to improving the well-being of those who reside there. However, determining how to alter the built environment in order to increase place identity is a difficult task to achieve. Walkability is a good mechanistic link between the built environment and place identity. Walkability is comprised of a suite of factors that take into consideration both the natural and built environment. This thesis aims to determine if walkability is positively correlated with place identity in an extreme climate such as Phoenix. To test this, ecosystem services and disservices are used as factors to measure overall walkability. We found that access to recreational opportunities, aesthetic features of the pathway, and safety were all significant predictors of place identity. This has positive implications for walkable infrastructure to be strengthened in desert cities.

For many species, migration evolves to allow organisms to access better resources. However, the proximate factors that trigger these developmental changes, and how and why these vary across species, remain poorly understood. One prominent hypothesis is that poor-quality food promotes development of migratory phenotypes and this has been clearly shown for some polyphenic insects. In other animals, particularly long-distance bird migrants, it is clear that high-quality food is required to prepare animals for a successful migration. We tested the effect of diet quality on the flight behaviour and morphology of the Mongolian locust, Oedaleus asiaticus. Locusts reared at high population density and fed low-N grass (performance-enhancing for this species) had enhanced migratory morphology relative to locusts fed high-N grass. Furthermore, locusts fed synthetic diets with an optimal 1 : 2 protein : carbohydrate ratio flew for longer times than locusts fed diets with lower or higher protein : carbohydrate ratios. In contrast to the hypothesis that performance-degrading food should enhance migration, our results support the more nuanced hypothesis that high-quality diets promote development of migratory characteristics when migration is physiologically challenging.

Fire is one of the earliest and most common tools used by humans to modify the earth surface. Landscapes in the Yucatán Peninsula are composed of a mosaic of old growth subtropical forest, secondary vegetation, grasslands, and agricultural land that represent a well-documented example of anthropogenic intervention, much of which involves the use of fire. This research characterizes land use systems and land cover changes in the Yucatán during the 2000–2010 time period. We used an active fire remotely sensed data time series from the Moderate Resolution Imaging Spectroradiometer (MODIS), in combination with forest loss, and anthrome map sources to (1) establish the association between fire and land use change in the region; and (2) explore links between the spatial and temporal patterns of fire and specific types of land use practices, including within- and between-anthromes variability. A spatial multinomial logit model was constructed using fire, landscape configuration, and a set of commonly used control variables to estimate forest persistence, non-forest persistence, and change. Cross-tabulations and descriptive statistics were used to explore the relationships between fire occurrence, location, and timing with respect to the geography of land use. We also compared fire frequencies within and between anthrome groups using a negative binomial model and Tukey pairwise comparisons. Results show that fire data broadly reproduce the geography and timing of anthropogenic land change. Findings indicate that fire and landscape configuration is useful in explaining forest change and non-forest persistence, especially in fragmented (mosaicked) landscapes. Absence of fire occurrence is related usefully to the persistence of spatially continuous core areas of older growth forest. Fire has a positive relationship with forest to non-forest change and a negative relationship with forest persistence. Fire is also a good indicator to distinguish between anthrome groups (e.g., croplands and villages). Our study suggests that active fire data series are a reasonable proxy for anthropogenic land persistence/change in the context of the Yucatán and are useful to differentiate quantitatively and qualitatively between and within anthromes.
