The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed …

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws

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

Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …

Analysis Of Gentrification And Green Spaces In East Austin, Texas, Carly Fordyce

Graduate Theses and Dissertations

Gentrification, the urban process that results from uneven development within cities, can cause unjust displacement of traditional, low-income residents in residential neighborhoods, and inequitable access to community services and benefits. Because of the negative social impacts that gentrification can have, many local governments and agencies have been known to attempt to mitigate changes by initiating different types of planning policies. Such policies usually apply changes in housing or zoning rules to enable lower-income residents to have access to housing and community amenities in the area. Another aspect resulting from gentrification that local government will try to rectify is low access …

Geese Management At The University Of Richmond, Virginia Mead

Environmental Studies Senior Seminar Projects

Geese are a nuisance in all fifty states and particularly at the University of Richmond. For the most part, Canada Geese, Branta canadensis, have effectively stopped migrating which has led them to be a problem for the surrounding ecosystem (Handwerk, 2021). The university has taken some preliminary steps to discourage geese from inhabiting our campus, but none have proven to be effective in the long run. To answer the question of how to deter geese from hanging out on campus, I assessed various geese management practices with the intention that the university could potentially adopt one of the practices. Our …

Sharing Air: A Review And Application Of Effective Methods Of Communicating Temperature Data, Claire A. King

Environmental Studies Senior Seminar Projects

One’s residence should not determine an individual’s health or lifespan. Further, if the environment where someone lives is detrimental to one’s health, that information ought to be shared with him or her. Surface heat exposure poses dangers to human health, and surface temperature is influenced by surrounding environmental factors. Surface temperature and related environmental data should be shared with communities in formats that best meet local needs. It is a matter of environmental and health justice. On July 15, 2021, a team of citizen scientists united under the Virginia Heat Watch project to collect surface temperature data in ten localities …

Down The Drain: Stormwater Management Effects On The Quality Of The Westhampton Lake, Indya Woodfolk

Environmental Studies Senior Seminar Projects

This paper examines incidents of illicit discharges on the University of Richmond campus as outlined by the City of Richmond's MS4 permit. Illicit discharges contaminate the Westhampton Lake by flowing from our storm drains directly into the Westhampton Lake. I detected incidents of illicit discharges by performing visual inspections as guided by numerous scholarly articles. The visual inspections were done with a special consideration of land use on campus. Along with the visual inspections, I inspected the storm drains during a dry weather event to find whether there was any flow during this period. In this study, I found several …

The scope of this proposal focuses on the Office of International Education and study abroad travel, which accounts for a large amount of emissions in the University’s portfolio. The purpose of this study was to propose a program to the Office of International Education which oriented students towards sustainability while they engaged in a study abroad …

Red Wolf Reintroduction: Land Ownership And Protection Status Analysis, Anna Frisbie

Environmental Studies Senior Seminar Projects

Red wolves (Canis rufus) are critically endangered, and currently the only wild population exists in northeast NC (“Red Wolf,” FWS, n.d.). Here, I use geospatial analysis to investigate the potential for another wild population to establish in the Delmarva Peninsula. I consider land ownership and protection status because these factors influence local public support (Nie, 2001; Naughton-Treves et al., 2003; Berger-Tal et al., 2020), as well as reintroduction success (Carroll et al., 2003; Wolf & Ripple, 2018). I compare the ownership and protection status of land in the Delmarva Peninsula to that in the Albemarle Peninsula, where the red wolf …

Analysis of each individual nutrient included the comparison of its minimum, maximum, and mean level relative to recommended criteria provided …

Unfair: Investigating The Links Between Richmond’S Air Quality Issues And Environmental Racism, Charles Miller

Environmental Studies Senior Seminar Projects

With breathable air being a resource inequitably distributed among populations based on race and socioeconomic status, this study’s objective was to analyze heat and air quality distributions in Richmond, Virginia and provide recommendations for minimizing its effects throughout the city. Richmond provided an ideal subject for this analysis as it has a lengthy history of racial segregation and discrimination and is one of the worst ranking cities for Asthma sufferers. Background was given on environmental racism as a means of systemic disproportionate pollution distribution to minorities, urban air pollution( via Fine Particulate Matter/PM 2.5) and the historical housing segregation process …

Tropical Cyclone Translation Speeds In The Northern Atlantic Ocean, Marybeth Melcher

Honors Theses

Over the past 40 years, tropical cyclones have caused over $1,076.9B in damage in the United States. The fatalities from tropical cyclones are just as devastating. Hurricane Katrina of 2005 caused over 1,800 deaths; Harvey in 2017 just under 90 deaths; Ike of 2018 took 112 deaths; and horrifically, Maria of 2017 claimed nearly 3,000 lives. The destruction that tropical cyclones have caused is astronomical, and a factor of tropical cyclones that is responsible for this level of destruction is their translation speeds. Tropical cyclone translation speed (TCTS) is the speed at which a hurricane is moving--the duration of time …

Economics Of Red Wolf Reintroduction, Logan West

Environmental Studies Senior Seminar Projects

In any animal reintroduction, one main component that is heavily evaluated is the economics of the reintroduction process of introducing an endangered animal to a specific area. Red wolves in specific, have a strong economic correlation between ecotourism and economics, as red wolves are an almost extinct species. In this analysis, I examined the economics of ecotourism as a benefit for red wolf reintroduction into the Delmarva. Additionally, I further examined how ecosystem services are an additional benefit to the economics in Delmarva. I used two case studies in my analysis to determine if the Delmarva Peninsula would enhance economically …

Invasive Plant Management At Huguenot Flatwater, Antonia Kempe

Environmental Studies Senior Seminar Projects

Invasive plants have become a wicked problem of the 21st century. Brought to areas outside of their native range by humans, they cause ecological and economic harm by disrupting ecosystem dynamics that in turn affect humans. Management methods include mechanical, chemical, and biological treatments, but each of these have their own advantages and limitations, which further adds to the complexities of invasive plant management. Units of the James River Park System in Richmond, Virginia are plagued by invasive plants, which are managed by the Invasive Plant Task Force. One of these units, Huguenot Flatwater, is overrun by invasive plants but …

Social Vulnerability, Diabetes, And Obesity In Georgia, Danny Jang

Symposium of Student Scholars

This project examines factors of health geography and population geography by examining the spatial correlation between diabetes and obesity prevalence among the population of Georgia. Diabetes and obesity are closely linked together, however, they are still far apart in various aspects which can be from personal to environmental impacts like geographical locations. This research attempts to investigate diabetes and obesity prevalence by examining the SVI of given counties of a state. This project uses data from the Atlanta-based Centers for Disease Control and Prevention (CDC) and Opendata (which can be found on ESRI). Future studies can examine these health factors …

Shocking: Using Machine Learning Techniques To Nowcast Lightning Strikes From Station Level Data, Michael D. Broussard

LSU Master's Theses

Lightning strikes are incredibly common and potentially hazardous. Lightning can lead to loss of life, property damage, or can trigger other hazardous events like wildfires. They are also the result of incredibly complex physical processes in the atmosphere, making it challenging to predict strikes. However, given the extensive data and robust analytical techniques available, machine learning methods could be used to establish data relationships between lightning strikes and ground-level atmospheric measurements. Such a model could be used to provide any surface-based weather station with a method for predicting incoming strikes, making it easier to avoid the potentially hazardous effects of …

Short-Term 2d And 3d Geomorphic Change Detection At A Public Park On Lake Michigan Using Uas Remote Sensing Techniques, Scott Patrick Fitzgerald

Masters Theses

The high-water level of Lake Michigan (LM) in the past few years has led to significant periods of erosion and increased the risk to private property owners on the coast. To cope with this, many property owners on the coast of LM have constructed coastal protections, some opting for seawalls. Previous studies have assessed the effects of seawalls but disagreed on their impacts, and only laboratory studies were able to establish their range of influence. Using a different method to study their effects will be pertinent to understanding them.

This research aims to use a higher temporal and spatial resolution …

Using Deep Learning And Uav Imagery To Detect Elkhorn Coral In St. Croix’S East End Marine Park, Samuel Wyatt

Master's Theses

Elkhorn coral, or Acropora palmata, is an important reef building species that promotes species abundance and other ecological services to the communities in the US Virgin Islands. We captured high resolution imagery of a reef in St. Croix’s East End Marine Park using a Wingtra One UAV. We then used deep learning techniques to detect individual coral colonies. We compared two deep learning models, FasterRCNN and MaskRCNN, and found that the models achieved accuracy shores up to 0.78. These scores improved when examining only larger corals in shallow waters. The model was able to both detect Elkhorn coral and …

Feasibility Of Introduced Species Into The Westhampton Lake For Pollution Control, Kathryn Grage

Environmental Studies Senior Seminar Projects

Westhampton Lake, located at the University of Richmond in Virginia is a man made lake that feeds into the James river. The lake itself suffers from pollution and above average nutrient loads from external sources. There have been efforts to try to reduce some pollution from the lake but this research proposes and explores the viability of introducing species into the lake for the same purpose. Two types of animals proposed for introduction into the lake are common carp (Cyprinus carpio) and freshwater mussels (Bivalvia: Unionidae). Sterilized common carp are proposed as a short term solution to removal of invasive …

Tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is currently considered to be one of the most destructive insect pests of tomatoes worldwide. The present study was conducted in three study sites along Ruaha River Basin, Iringa, Tanzania, to assess community awareness about T. absoluta infestation and its management. The study also evaluated the susceptibility of three tomato varieties against T. absoluta in a greenhouse setting, as well as the effect of colours of traps and doses of pheromone in attracting T. absoluta in a field environment. The field survey revealed that 97% of the respondents were aware of the …

Landslide Detection In The Himalayas Using Machine Learning Algorithms And U-Net, Sansar Raj Meena, Lucas Pedrosa Soares, Carlos H. Grohmann, Cees Van Westen, Kushanav Bhuyan, Ramesh P. Singh, Mario Floris, Filippo Catani

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Event-based landslide inventories are essential sources to broaden our understanding of the causal relationship between triggering events and the occurring landslides. Moreover, detailed inventories are crucial for the succeeding phases of landslide risk studies like susceptibility and hazard assessment. The openly available inventories differ in the quality and completeness levels. Event-based landslide inventories are created based on manual interpretation, and there can be significant differences in the mapping preferences among interpreters. To address this issue, we used two different datasets to analyze the potential of U-Net and machine learning approaches for automated landslide detection in the Himalayas. Dataset-1 is composed …
