Cation exchange, a cornerstone of soil chemistry and nutrient cycling, is a fundamental chemical process that occurs in soils, sediments, membranes, and other solid materials. It involves the interchange of positively charged ions, or cations, between a solid matrix and a surrounding solution. This process is crucial in various natural and engineered systems, leading to a range of applications across different fields.

This dissertation presents an extensive investigation into the applications of cation exchange in the fields of biochar and bioenergetics, encompassing three distinct aims. The first aim concentrates on the surface oxygenation of biochar through ozonization, aiming to achieve …

Appalachia In The Anthropocene: An Approach To Understanding Neo Appalachian Narratives As An Affective Ecology, Rachel Michel Bates

English Theses & Dissertations

Appalachia is all too often a commodified and mythologized place in the American consciousness. Yet the lived experience of Appalachia is one complicated by widescale ecological devastation, high poverty rates, and most recently, a devastating opioid crisis. Though much of Appalachian literature continues to dwell in an old vision of Appalachia, an endeavor Zackary Vernon terms post-Appalachian, I argue that a subset of texts published around the turn of the millennium, a time when many of the labor-dependent, exploitative industries such as logging, hydro damming, and coal mining were no longer at work in the region, reveal a shift in …

This capstone project answers the question: How can educators help urban elementary students become more connected to supporting the health of their local watersheds through the use of aquatic macroinvertebrates? Through research into this topic, it is concluded that place-based environmental education that allows students to …

The Effects Of Phenological Shifts On The Reproductive Success Of Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea) In The Gulf Of Maine, Jamie W. Dinella

Student Publications

Climate change is resulting in ecosystem-wide consequences, including shifts in the geographical distribution of species and the timing of biological events, or phenology. The rapidly warming Gulf of Maine hosts breeding populations of migratory common terns (Sterna hirundo) and Arctic terns (Sterna paradisaea). I used nest check data (2013-2022) and eggshell membrane stable isotope data (2022) from Petit Manan Island in the Gulf of Maine to examine the causes and consequences of variation in phenology in common and Arctic terns. I hypothesized that the timing of an individual’s breeding was impacted by their foraging behavior and that female terns that …

How Territoriality And Sociality Influence The Habitat Selection And Movements Of A Large Carnivore, K Whitney Hansen, Nathan Ranc, John Morgan, Neil R Jordan, J Weldon Mcnutt, Alan Wilson, Christopher C Wilmers

Faculty, Staff and Student Publications

While territoriality is one of the key mechanisms influencing carnivore space use, most studies quantify resource selection and movement in the absence of conspecific influence or territorial structure. Our analysis incorporated social information in a resource selection framework to investigate mechanisms of territoriality and intra‐specific competition on the habitat selection of a large, social carnivore. We fit integrated step selection functions to 3‐h GPS data from 12 collared African wild dog packs in the Okavango Delta and estimated selection coefficients using a conditional Poisson likelihood with random effects. Packs selected for their neighbors' 30‐day boundary (defined as their 95% kernel …

Although KYTC has a long track record of executing complex projects, doing so is increasingly challenging due to staff attrition and the attendant loss of institutional knowledge. Today’s entry- and mid-level project managers have more responsibilities than ever but lack a trusted source of guidance to help them manage projects from development through completion. The objective of this study …

Effectiveness Of Aerial Monitoring Of Spatial And Temporal Changes Of Santa Catalina Island Rhodolith Beds, Charnelle Wickliff

Capstone Projects and Master's Theses

The distribution and abundance of rhodolith beds off Santa Catalina Island, California are impacted by natural and anthropogenic factors. These complex, unattached coralline habitats provide food and shelter for important species; however, little is known about temporal variation in bed cover and distribution. Abiotic factors like heavy storms and surge can change bed boundaries and shape. Anthropogenic factors, such as disturbance from mooring chains, can create patchiness within beds. Studies of bed distribution and tracking changes in habitats have historically been done using labor-intensive SCUBA diving. This approach has excellent resolution at small scales but is limited in the temporal …

Exploration Of The Mental Health Impacts Of Drought On Rural Nebraskans Via Remembered Perceptions, Grace Schleining

Department of Environmental Studies: Undergraduate Student Theses

Drought is a sociological phenomenon. It is a well-known occurrence across the midwestern United States; the drying out of the soil, the failing of crops, and the constant dryness and heat… this is all drought. Inspired by my earliest memory of this climate phenomenon I sought to determine whether we can identify evidence of negative mental health impacts and/or well-being in rural Nebraskans due to drought, thus my research question: Can we identify negative effects of drought on rural Nebraskan mental health and/or wellbeing? In this study, rural Nebraska community members, who are involved with the agricultural sector, were interviewed. …

Nonprofits Should Adopt A User-Centric Change Model To Scale Corporate Environmental Action Faster, Doug Miller

Journal of Nonprofit Innovation

Pollution levels and ecosystem degradation continue to worsen, suggesting the insufficiency of current approaches to reverse these problematic trends. For environmental nonprofits, the current theory of change revolves around developing techno-economic analysis about environmental problems and available solutions, building public awareness around this analysis, and motivating decision makers to set goals. Given present environmental realities and the limited success of their current theory of change, environmental nonprofits should transform how they execute their work, what they produce, and how they coordinate with each other. Instead, nonprofits should begin putting the user—business decision makers as well as policymakers—front and center as …

Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Marine Cyanobacterium Synechococcus Sp. Ccmp 1334, Alyssa K. Sharbaugh

LSU Master's Theses

The marine cyanobacterium Synechococcus sp. CCMP 1334 was grown in a continuous culture system on a 12:12 h light:dark cycle at all combinations of low and high pCO2 (400 and 1000 ppmv, respectively), nitrate availability (nitrate-limited and nutrient-replete conditions), and temperatures of 21°C, 24°C, 28°C, 32°C, and 35°C. The maximum median nutrient-replete growth rate was ~1.15 d−1 at 32 –35°C. Median growth rates at 1000 ppmv pCO2 were higher than those at 400 ppmv at all temperatures, but most of the differences were statistically insignificant. Carbon:nitrogen ratios were independent of pCO2 at a fixed relative growth rate but decreased with …

The Impact Of Covid-19 Pandemic On Carbon Emissions: Empirical Evidence From China, Yanwei Lyu, You Wu, Wenqiang Wang, Jinning Zhang

Bulletin of Monetary Economics and Banking

In this study, we investigate the short-term impact of the COVID-19 pandemic on China’s carbon emissions. We use data for a panel of 30 Chinese provinces over the period January 2020 to December 2020. The results indicate that carbon emissions in China decreased considerably during the COVID-19 outbreak. This finding remains robust when we use different proxies for core variables. The pandemic had a more pronounced impact on carbon emissionsin regions with a surplus of carbon emission allowances, and the negative effects of the pandemic on carbon emissions were greater in the first half of 2020 compared to the second …

Natural Warming Differentiates Communities And Increases Diversity In Deep-Sea Ridge Flank Hydrothermal Systems, Anne M. Hartwell, Anna E. Wheat, Jennifer A. Dijkstra

Center for Coastal and Ocean Mapping

Ridge Flank Hydrothermal Systems have discrete pockets of fluid discharge that mimic climate-induced ocean warming. Unlike traditional hydrothermal fluids, those discharged by Ridge Flank Hydrothermal Systems have a chemical composition indistinguishable from background water, enabling evaluation of the effect of warming temperature. Here we link temperature and terrain variables to community composition and biodiversity by combining remotely operated vehicle images of vent and non-vent zone communities with associated environmental variables. We show overall differences in composition, family richness, and biodiversity between zones, though richness and diversity were only significantly greater in vent zones at one location. Temperature was a contributing …

Changing The Culture Of Ecology From The Ground Up, Elsa Abs, Moira Hough

Michigan Tech Publications

We are two early career soil ecologists in academia who entered the field of soil ecology with the goal of studying soil-climate feedbacks to make meaningful contributions to climate change mitigation. Although our training and research extensively focused on the effects of climate change on soil ecosystems, we were not trained during our PhD nor incentivized as postdocs to work on solutions for climate change mitigation. So the question we ask here is: Given the consensus among ecologists about the urgency of the climate crisis, why is our field not promoting more solutions-oriented research in training and practice? In this …

Sharing Stories Of Development: How School Leaders Perceive Developing A Trauma-Informed School, Mandy L. Cyr

Doctor of Education Program Dissertations

ABSTRACT

This narrative inquiry explored how educational leaders perceive the development of a trauma-informed school. A trauma-informed school acknowledges the impact of trauma and responds by integrating effective practices, programs, and procedures to build resilience. The problem addressed by this study is, with rising numbers of adverse childhood experiences (ACEs), school staff lack targeted skills to help students mitigate trauma. Further, this qualitative study fills the gap in literature by providing the lived experiences of educational leaders in developing trauma-informed schools. Through narrative research, semistructured interviews which lasted up to 60 minutes were individually conducted with five educational leaders who …
