Student Theses 2015-Present

As a society evolving and innovating at a pace faster than ever before seen in human history, we find ourselves at a crossroads of dealing with planetary boundaries and improving social standards. We are met with a crisis just thirty years away; the crisis of needing to be able to effectively and sustainably feed ten billion people across the globe. The 20th century brought on a booming age for industrializing the food system in order to increase yield and thus profit. The new process was a significant breakthrough at its time, but now we must face the question of when ...


Microbial Assemblages In Relation To Host And Environmental Surroundings, Mark Fischer May 2021

Microbial Assemblages In Relation To Host And Environmental Surroundings, Mark Fischer

Senior Honors Theses

The goal of this study was to determine if the microbiome between two crayfish microhabitats were different from one other, in addition to the surrounding water and sediment. This project was a field-based study in which all environmental samples and crayfish were collected from a central Virginian freshwater stream. Molecular techniques were employed to sequence bacterial DNA from the various sample types and Qiime 2 was used to analyze statistical differences. The results from this study aligned well with the initial hypothesis in that the alpha-diversities between all of the sample types were statistically different (P<0.05) except for the gill chamber and surrounding water microbial assemblages. In addition, the Beta-diversity was statistically different when the bacterial composition of one sample type was compared to the composition of the other samples (P<0.05). This data aids in our understanding of the significance of microbes within a freshwater ecosystem and how they are distributed among freshwater organisms, such as the crayfish.

Impact Of Whitetail Deer Overpopulation With Hunting On The Decline, Matthew J. Lamprinos

English Department: Research for Change - Wicked Problems in Our World

The whitetail deer is a key species for Pennsylvania’s forests, but their ecological balance has been disturbed by unregulated growth and urban sprawl. The deer population in Pennsylvania has exploded since the 1880’s causing a wide range of damage on the ecosystem, and humans. To reduce deer populations to sustainable levels, the Pennsylvania Game Commission relies heavily on hunters to dedicate time in the fall to go out and fill the tags the they issue. Hunter participation all around the world is decreasing for a variety of reasons. Fewer hunters out in the field causes revenue losses for ...

Too Little, Too Late: Congress's Attempt To Regulate Forever Chemicals Through Military Appropriations, Michael Heard Snow Feb 2021

Too Little, Too Late: Congress's Attempt To Regulate Forever Chemicals Through Military Appropriations, Michael Heard Snow

William & Mary Environmental Law and Policy Review

Per- and polyfluoroalkyl substances, shortened to “PFAS,” are a broad class of approximately 4,000 to 6,000 industrial chemicals characterized by a carbon chain saturated with fluorine molecules. This structure, dominated by carbon-fluorine bonds, is one of the most stable known chemical structures—and it is this stability that lies at the core of both the usefulness and the greatest issues surrounding PFAS. They are generally non-reactive except at tailored “active sites” and they never break down naturally—leading to the nickname “forever chemicals.” The persistence of their structures creates a plethora of desirable characteristics: PFAS are grease-resistant, waterproof ...


How A Low-Cost Method For Cumulative Water-Sampling Shows Need For Improvement Of Legal Public-Contact Standards In The United States, Samuel Kessler Feb 2021

How A Low-Cost Method For Cumulative Water-Sampling Shows Need For Improvement Of Legal Public-Contact Standards In The United States, Samuel Kessler

Grawemeyer Colloquium Papers

Across the world, it is estimated that 4.5 billion people live near water sources “impaired” for use or contact. Standards for human-interaction are established by international organizations such as the WHO, and legislative bodies from national to local levels with jurisdiction over the quality of our waterways to ensure public & environmental health. Standards are often assessed from “grab-samples” taken from a waterbody at a certain time, with a minimum number analyzed. Water-quality standards in the United States are enforced under the Clean Water Act (CWA) via the Environmental Protection Agency (EPA), applying to “waters of the United States” (WOTUS ...

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Permafrost thaw in northern ecosystems may cause large quantities of carbon (C) to move from soil to atmospheric pools. Because soil microbial communities play a critical role in regulating C fluxes from soils, we examined microbial activity and greenhouse gas production soon after permafrost thaw and ground collapse (into collapse‐scar bogs), relative to the permafrost plateau or older thaw features. Using multiple field and laboratory‐based assays at a field site in interior Alaska, we show that the youngest collapse‐scar bog had the highest CH4 production potential from soil incubations, and, based upon temporal changes in porewater ...

Sectional Model Of A Prairie Buffer Strip In A Laboratory Flume For Water Quality Research, Andrew J. Craig, Michelle L. Soupir, Chris R. Rehmann

Agricultural and Biosystems Engineering Publications

Vegetative buffers have shown promising results in reducing runoff volume, sediment, nutrients, and manure‐borne contaminants in runoff from agricultural fields. Although these vegetative buffer systems have been extensively tested in field and plot‐scale studies that utilize either natural or simulated rainfall, studies of such systems under highly controlled conditions in the laboratory have been limited. Here, we present the development of a new system for laboratory testing of a full‐scale, sectional, physical model of a new practice under the Continuous Conservation Reserve Program (CRP) Clean Lakes, Estuaries, and Rivers (CLEAR) Initiative, CP‐43 Prairie Strips. This work ...


Plastic Debris In The Laurentian Great Lakes System, North America: Analysis Of Types, Abundances, And Sources, Ian A. Arturo Feb 2021

Plastic Debris In The Laurentian Great Lakes System, North America: Analysis Of Types, Abundances, And Sources, Ian A. Arturo

Electronic Thesis and Dissertation Repository

Understanding plastic pollution in the Laurentian Great Lakes system requires investigation of all plastic debris sizes and categories. Visible polymeric debris (VPD) mainly characterize shorelines, and microplastics (MPs;mm) are found in benthic and beach sediment. Field sampling of VPD from all five Great Lakes, visual and chemical identification of VPD types, and implementation of a matrix scoring technique (MST) indicate that plastic industries, urban areas, and shoreline recreation are major sources of VPD. Sampling for MPs in the St. Clair system, followed by preliminary density separation, and microscopy, suggest that wastewater treatment plants are a major source. This work ...

Psychology Faculty Articles and Research

Despite Greta Thunberg's popularity, research has yet to investigate her impact on the public's willingness to take collective action on climate change. Using cross‐sectional data from a nationally representative survey of U.S. adults (N = 1,303), we investigate the “Greta Thunberg Effect, or whether exposure to Greta Thunberg predicts collective efficacy and intentions to engage in collective action. We find that those who are more familiar with Greta Thunberg have higher intentions of taking collective actions to reduce global warming and that stronger collective efficacy beliefs mediate this relationship. This association between familiarity with Greta Thunberg ...

A Review Of Measuring Ecosystem Resilience To Disturbance, Chuixiang Yi, Nathan Jackson Jan 2021

A Review Of Measuring Ecosystem Resilience To Disturbance, Chuixiang Yi, Nathan Jackson

Publications and Research

Resilience is the central concept for understanding how an ecosystem responds to a strong perturbation, and is related to other concepts used to analyze system properties in the face of change such as resistance, recovery, sustainability, vulnerability, stability, adaptive capacity, regime shift, and tipping point. It is extremely challenging to formulate resilience thinking into practice. The current state-of-art approaches of assessing ecosystem resilience may be useful for policy makers and ecosystem resource managers to minimize climatological or natural disaster related impacts. Here, we review the methods of assessing resilience and classify and limit them to three cases: (1) forest resilience ...


Moving Beyond ‘More Crop Per Drop’: Insights From Two Decades Of Research On Agricultural Water Productivity, Meredith Giordano, Susanne M. Scheierling, David O. Tréguer, Hugh Turral, Peter G. Mccornick Jan 2021

Moving Beyond ‘More Crop Per Drop’: Insights From Two Decades Of Research On Agricultural Water Productivity, Meredith Giordano, Susanne M. Scheierling, David O. Tréguer, Hugh Turral, Peter G. Mccornick

Daugherty Water for Food Global Institute: Faculty Publications

Concern over increasing water scarcity has led to the introduction of the concept of agricultural water productivity and an emphasis on interventions to achieve ‘more crop per drop’. Yet, a strong debate continues on how the concept is to be defined and used. Drawing largely from the irrigation literature, the origins of the concept and its methodological developments are reviewed, and its use in applied work over two decades is discussed. Based on this analysis of conceptual and applied research, key insights into the concept’s contributions and limitations are presented, as well as opportunities for further refinements.

Daugherty Water for Food Global Institute: Faculty Publications

Nanomaterials (NMs), both natural and synthetic, are produced, transformed, and exported into our environment daily. Natural NMs annual flux to the environment is around 97% of the total and is significantly higher than synthetic NMs. However, synthetic NMs are considered to have a detrimental effect on the environment. The extensive usage of synthetic NMs in different fields, including chemical, engineering, electronics, and medicine, makes them susceptible to be discharged into the atmosphere, various water sources, soil, and landfill waste. As ever-larger quantities of NMs end up in our environment and start interacting with the biota, it is crucial to understand ...

Months-Long Spike In Aqueous Arsenic Following Domestic Well Installation And Disinfection: Short- And Long-Term Drinking Water Quality Implications, Melinda L. Erickson, Elizabeth D. Swanner, Brady A. Ziegler, Jeff R. Havig

Geological and Atmospheric Sciences Publications

Exposure to high concentration geogenic arsenic via groundwater is a worldwide health concern. Well installation introduces oxic drilling fluids and hypochlorite (a strong oxidant) for disinfection, thus inducing geochemical disequilibrium. Well installation causes changes in geochemistry lasting 12 + months, as illustrated in a recent study of 250 new domestic wells in Minnesota, north-central United States. One study well had extremely high initial arsenic (1550 µg/L) that substantially decreased after 15 months (5.2 µg/L). The drilling and development of the study well were typical and ordinary; nothing observable indicated the very high initial arsenic concentration. We hypothesized that ...


Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler Jan 2021

Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler

Graduate Theses, Dissertations, and Problem Reports

Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In ...


Fluoride Removal With Augmented Bentonite In Drinking Water And Community Perceptions In Arusha, Tanzania, Kara Okular Dec 2020

Fluoride Removal With Augmented Bentonite In Drinking Water And Community Perceptions In Arusha, Tanzania, Kara Okular

Electronic Theses and Dissertations

High fluoride concentrations in drinking water affect millions of people around the world. The World Health Organization recommended a fluoride concentration in drinking water of ≤ 1.5 mg/L; fluoride above this concentration can cause long-term dental and skeletal fluorosis. Fluoride imparts no taste to water; therefore, people do not realize that they are ingesting high fluoridated water. Researchers sought to develop a material to remove fluoride from drinking water through sorption. Aluminum was used to form a double ionic layer on the bentonite clay surface. Once mixed in contaminated water, a coagulant, ferric sulfate, was used to separate the ...

Resource Partitioning And Density Drivers Of Two Endangered Large Felids: Amur Tiger (Panthera Tigris Altaica) And Amur Leopard (Panthera Pardus Orientalis) In The Russian Far East, Dina Matiukhina

Dissertations and Theses

In Russia, long-term conservation interventions have bolstered the critically endangered Amur leopard (Panthera pardus orientalis) as well as their dominant competitor, the endangered Amur tiger (Panthera tigris altaica). Within the Land of the Leopard National Park, I investigated the potential for tigers to displace or suppress leopards. I used data from winter track surveys to fit resource selection functions and camera trap surveys to both fit spatially-explicit capture-recapture models and document leopard productivity. I found no evidence of habitat displacement or numerical limitation of leopards by tigers in this region. Leopards resource selection was defined by landscape features and density ...


Influence Of Some Climatic Elements On Radon Concentration In Saeva Dupka Cave, Bulgaria, Peter Nojarov, Petar Stefanov, Karel Turek Dec 2020

Influence Of Some Climatic Elements On Radon Concentration In Saeva Dupka Cave, Bulgaria, Peter Nojarov, Petar Stefanov, Karel Turek

International Journal of Speleology

This study reveals the influence of some climatic elements on radon concentration in Saeva Dupka Cave, Bulgaria. The research is based mainly on statistical methods. Radon concentration in the cave is determined by two main mechanisms. The first one is through penetration of radon from soil and rocks around the cave (present all year round, but has leading role during the warm half of the year). The second one is through thermodynamic exchange of air between inside of the cave and outside atmosphere (cold half of the year). Climatic factors that affect radon concentration in the cave are temperatures (air ...
