The Effects Of Impervious Land Cover And Red Tide (Karenia Brevis) On The Florida Manatee (Trichechus Manatus Latirostris) In The Gulf Coast Of Florida, Anna Compton

Honors College Theses

Red tide, caused by the dinoflagellate Karenia brevis, is an algal bloom event that occurs annually in the West Florida Continental Shelf. The algae releases brevetoxin, a toxin that can be fatal to wildlife in high concentrations. These algal bloom events are thought to be exacerbated by warming ocean temperatures and increased nutrient runoff from urbanization. Red tide is responsible for the mass mortality of various marine organisms like the Florida manatee (Trichechus manatus latirostris). This study analyzes the changes in nutrient runoff and sea surface temperatures, and how these factors affected red tide cell concentrations and Florida manatee mortalities …

Dendroclimatic Response Of The Wet Miombo Woodland Species: A Case Study Of Mufulira District, Copperbelt Province, Zambia, Collins Chibuye Malubeni

All-Inclusive List of Electronic Theses and Dissertations

Zambia is a tropical, landlocked country that lies in the South-Central part of Africa. The climate in Zambia includes distinct dry and rainy seasons, mainly influenced by the north-south movement of the Intertropical Convergence Zone (ITCZ), which shifts seasonally. This research is focused on understanding the relationship between tree growth and climate using dendrochronology. Forty-nine tropical species, including Julbernardia paniculata, Brachystegia longifolia, and Pericopsis angolensis, were analysed for dendroclimatic potential, and 70% showed clear ring formation, indicating that trees in this locality produce distinct annual ring boundaries. For the single species chronology, thirteen cores from eight trees that were initially …

The Personality Of Place: Physical Geography And The Shaping Of The Nineteenth-Century German Immigrant Ethnic Identity, Abigail Ward

Honors Theses

In the nineteenth century alone, approximately five million German-speaking immigrants arrived in America. However, the motivations of these individuals for moving to America, far from identical, were nearly as numerous as the individuals themselves. The German ethnic identity in America was not uniform, but the expression of many factors having to do with both the Vaterland and the new land. These factors ranged from the timing of emigration, which was largely influence by religious, political, and economic upheaval in Europe, to each German’s system of values, which dictated the kind of future he saw for himself and therefore where he …

From Guyana To Queens: The Formation Of The Indo-Guyanese Ethnoburb In New York City, 1970-1990, Lianne R. Persaud

Theses and Dissertations

Expanding on Li’s concept of ethnoburbs, this study examines Indo-Guyanese settlement in Little Guyana, Queens (1970–1990). I propose the Vertical Enclave Model, which suggests that multi-family homeownership and internal rental markets facilitated the residential permanence of working-class individuals. The IPUMS Census microdata corroborates this community’s reliance on metropolitan integration, thereby refuting traditional self-sufficient ethnic enclave theories.

The "Evil Forest" As Threshold: A Computational Eco-Feminist Study Of The Forest In Nigerian Fantasy, Cynthia O. Mbagwu

Department of English: Dissertations, Theses, and Student Research

This study examines the representation of the “evil forest” in Nnedi Okorafor’s Zahrah the Windseeker and Ukamaka Olisakwe’s Don’t Answer When They Call Your Name, arguing that the forest functions as a liminal threshold that catalyses female transformation. Combining close reading with computational tools like TF-IDF keyword extraction in Ruby and sentiment analysis using VADER, the project investigates how pre-colonial and colonial connotations of the “evil forest” are re-imagined in contemporary Nigerian fantasy fiction. By segmenting each narrative into pre-liminal, liminal, and post-liminal phases, the study tracks shifts in sentiment toward the forest and correlates them with thematic developments …

Factors Affecting Pedestrian-Vehicle Conflicts: An Empirical Analysis, Christo D. Jamo

Honors Scholar Theses

The number of pedestrian deaths increased by 78% between 2009 and 2023, while other motor vehicle crash deaths increased by 13% in the same period [1]. To identify potential pedestrian safety measures, this study analyzed the effects of location-based demographics, pedestrian phasing type, and other physical infrastructure and behavior variables on the probability of pedestrian-vehicle conflicts at signalized intersections, which is a surrogate measure of crash risk. Data were collected from 55 intersections in Connecticut, and the pedestrian-vehicle interactions were classified by severity based on the Swedish Traffic Conflict Technique: undisturbed passage, potential conflict, minor conflict, or serious conflict. Because …

Distribution Mapping And Modeling Of The Invasive Japanese Knotweed, Jossalyn Rogalski

Masters Theses

This thesis investigates the distribution of invasive Japanese knotweed across Michigan. This plant poses significant challenges to land management due to its rapid growth, environmental impacts, and difficulty of removal once established. Using geographic information systems (GIS), remotely sensed data, and secondary environmental datasets, this research maps current infestations and analyzes key factors influencing the species’ growth and dispersal, such as soil composition, hydrology, land use, and a range of environmental variables, including climatic (annual mean temperature, temperature seasonality, annual precipitation, precipitation seasonality), elevation, vegetation and hydrological indices (NDVI, EVI, NDWI), percent tree cover, and distance to roads. Spatial analysis …

Conventional Vs. Regenerative Apple Orchard Management In Michigan, Anthony Poynter

Masters Theses

This study compares the variables and outcomes of a conventional apple orchard and a regenerative apple orchard production system in Kent County, Michigan. The premise is that conventional agriculture relies on high-input systems characterized by synthetic fertilizers, pesticides, herbicides, and fungicides, while regenerative agriculture focuses on long-term soil health, biodiversity, and ecological processes. These differences are important as soil degradation, nutrient loss, and environmental impacts are becoming too significant to ignore. Most research on alternative ways to farm, such as regenerative practices, is focused on annual crops, while perennial orchard systems, especially in the Great Lakes region, have gained limited …

Building Collaborative Capacity For Coexistence With The Montana Beaver Working Group, Shane Randle

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Despite beavers’ recent surge in popularity, prevailing negative attitudes and the persistence of beaver removal practices remain obstacles for those advocating living with beavers. The Montana Beaver Working Group (BWG) advances beavers’ role in ecological and community resilience through members’ collaborative efforts, including beaver-related restoration and conflict resolution projects. Bringing together people with diverse values and perspectives, the BWG builds collective understanding, develops a holistic vision for beavers in Montana, and supports members in pursuing it. As the group’s impacts and membership have grown, so too has their need to adapt. For my Civic Engagement Project, I strengthened the BWG’s …

Passive Microwave Remote Sensing Of Flash Drought Impacts On Vegetation, Quinton R. Deppert

School of Natural Resources: Dissertations, Theses, and Student Research

In 2002, Dr. Mark Svoboda characterized a new form of drought known as flash drought. Flash drought was defined as a rapid decline in vegetation health caused by severe heat and drought. In recent years, attempts to quantify the impacts of flash drought via precipitation, soil moisture, evapotranspiration, and temperature indicators have proliferated. What has rarely been quantified is what the rapid decline in vegetation health amid flash drought looks like through remote sensing. This is because vegetation health indices like the Normalized Difference Vegetation Index (NDVI) are derived from the visible and infrared regions of the electromagnetic spectrum and …

Fresh Phytoplankton Bloom Growth In The Fall And Its Control On Ocean Heating In The Pacific Arctic Region, Clare B. Gaffey, K E. Frey, Bonnie Light, Lee W. Cooper, Jacqueline M. Grebmeier

Geography

Delayed sea ice freeze-up and decreased sea ice extent in the Pacific Arctic region have altered light availability in marine waters, extending the ice-free season and increasing opportunities for photosynthetic activity and energy exchanges. This study investigates phytoplankton bloom progression during the fall using chlorophyll pigments and examines the impact phytoplankton have on heat distribution within the water column. Measurements of chlorophyll-a concentrations and its associated degradation product pheophytin were made in conjunction with optical measurements of light transmittance within the upper water column during the Synoptic Arctic Survey cruise in the Central Arctic Ocean and northeast Chukchi Sea in …

Evaluating Long-Term Seasonal Variability Of Aerosol Optical Properties In Colorado, Erin K. Boedicker, Andre Bergeron, Gerardo Carrillo-Cardenas, Dominik Kulakowski, John Rogan, Elizabeth Andrews, Gannet A. Hallar

Geography

Aerosol particles resulting from both wildfires and dust events introduce considerable uncertainty into both climate research and public health assessments. These challenges are becoming particularly evident in the western US. To gain a deeper understanding of western US aerosol properties, we analyzed 13 years (2011–2024) of surface in-situ aerosol optical data from Storm Peak Laboratory (SPL) in northwestern Colorado, and 6 years (2019–2024) of surface in-situ aerosol optical data from Table Mountain (BOS) in central Colorado. The aerosol optical properties at both sites demonstrate a strong summer wildfire smoke signal (peaking in August) and evidence of springtime dust events. BOS …

Empirical Line Calibration And Spectral Comparison Of Small Unmanned Aircraft Systems, Shimon Von-Rad Alexis Beazer

Graduate Theses and Dissertations

The increased usage of unmanned aircraft systems (UAS) for various applications has broadened access to high-resolution aerial imaging, a field with deep roots in geography, remote sensing, and geospatial science. Radiometric correction in satellite imagery has its origins in the early decades of Earth observation, with foundational work beginning alongside the launch of the first multispectral satellites and evolving through decades of research into atmospheric correction, sensor calibration, and reflectance modelling. As UAS adoption grows, research into atmospheric attenuation effects on UAS imagery becomes necessary. Empirical line calibration converts digital number values to surface reflectance and is used here to …

Using Satellite-Observed Geospatial Inundation Data To Identify The Impacts Of Floods On Firm-Level Performance: The Case Of China During 2000–2009, Pao-Li Chang, Fan Zheng

Research Collection School Of Economics

This paper compiles high-resolution geospatial inundation areas of China for the period 2000–2009 based on satellite imagery repositories filtered by the Global Flood Database (GFD). In parallel, we geocode a comprehensive firm-level dataset of China and combine these two sets of geospatial data to identify the set of inundated firms in each year of flood events, as well as the distances of all non-inundated firms from the inundated areas. Given the high-resolution inundation data, we adopt a generalized dynamic-panel specification to estimate dynamic and spatial spillover effects of floods on firm-level production activities (including outputs, capital and labor inputs, and …

The Geography Of Race: A Spatial Analysis Of Free People Of Color In The City Of Charleston (1790-1861), Alexandra Ullman

All Theses

In Charleston, South Carolina, for all but one year from 1790 to 1860, the enslaved and free Black population outnumbered that of the white. Through manumission, the process of an enslaved person gaining their freedom, the free Black population grew substantially and reached a peak in South Carolina during the nineteenth century. This large community of free people of color (FPOC), shifted the social climate by upsetting the balance of white power, thus increasing racial conflict, tension, and legislation that aimed to control the movement of FPOC.

Despite FPOC comprising a significant portion of the total population of Charleston, there …

Spiritual Gentrification Amid The Rise Of Platform Urbanism: "Wanghong Temples" And Emerging Buddhist Cultural Economies In Tianzhu Road, Hangzhou, China, Han Zhang, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This study scrutinizes how the Tianzhu Road in the Lingyin Community - a peri-urban area in Hangzhou ringed by a cluster of temples that constitutes a distinct spiritual enclave - has been reworked through a two-phase gentrification process driven by the spiritual aesthetics and platform logics. Drawing on a two-month ethnography and media content analysis, this study conceptualizes spiritual gentrification as a spiritual aesthetics and culture-oriented recalibration of urban space in which spiritual elements operate as symbolic capital, attracting culturally motivated entrepreneurs and aligning the spiritual atmosphere with slow-life values as an alternative to urban modernity. In particular, platform urbanism …

Public Pool Usage As Adaptation Against Urban Heat, Stefan Borsky, Eric Fesselmeyer

Research Collection College of Integrative Studies

This paper examines the relationship between urban heat and outdoor public pool usage. Using attendance data from all 53 outdoor public pools in New York City, we analyze nonlinear effects of heat on pool usage across socioeconomic contexts. Pool attendance rises sharply with heat, especially in low-income neighborhoods where alternative coping options are likely limited. We also find that public pools reduce heat-related emergency medical service calls. Our findings highlight the need for equitable investment in blue infrastructure to enhance urban climate resilience and demonstrate how this type of adaptive infrastructure can play a critical role in managing urban heat.

Increasing Accuracy Of Mapping Local Climatic Zones Using Building Height And Spectral Unmixing, Ian Douglas Stauffer

Masters Theses

Local climatic zone (LCZ) classifications are traditionally done using reflectance, population data, and often climatic data. The goal of this research is to utilize Google’s new “Open Buildings Temporal v1” building data set as well as “spectral unmixing”. With the objective of testing, assessing, and implementing this data set into the workflow of LCZ mapping. After testing the quality of the data against a validated LiDAR data set from the same year as a given “Open Buildings Temporal v1” band, I implemented it into the Random Forest machine learning process. Secondly, I justified the use of spectral unmixing as a …
