Wildfire Exposure To Critical Habitat Of Endangered And Threatened Species In California, Kristin Butcher
Wildfire Exposure To Critical Habitat Of Endangered And Threatened Species In California, Kristin Butcher
Master's Theses
Researchers, fire ecologists and wildlife managers are concerned about impact to endangered and threatened species and their critical habitat due to the projected increase in future wildfires. Wildfires have been studied in California for the last six decades and have been increasing at an alarming rate since the 1980’s. In this study, I use the 2018 spatial dataset for critical habitat of federally endangered and threatened species located in the state boundaries of California and compare it to a spatial dataset for wildfires that have occurred over the span of 32 years (1984 to 2016). Trends are derived from spatial …
Riparian Resilience In The Face Of Interacting Disturbances, Alexa S. Whipple
Riparian Resilience In The Face Of Interacting Disturbances, Alexa S. Whipple
2019 Symposium
Riparian systems of the dryland western United States provide critical ecosystem functions such as diverse habitat for numerous species, flood attenuation and essential water storage in water-limited environments. These systems have experienced long term disturbance from anthropogenic activities including the grazing of livestock in dryland riparian systems and near extirpation of a keystone riparian species, Castor canadensis (beaver). However, increasing frequency of large-scale wildfires and climate change driven weather is altering the severity and scale of riparian disturbance. Beaver restoration has been gaining use to address long term riparian disturbances, yet little is understood regarding the impact of restored beaver …
Nature As Privilege: How Environmental Racism Changes The Access To Fresh Air And The Effects On New York City’S Communities, Sarah C. Morrison
Nature As Privilege: How Environmental Racism Changes The Access To Fresh Air And The Effects On New York City’S Communities, Sarah C. Morrison
Student Theses 2015-Present
This paper serves to addresses the issue of environmental racism in relation to New York City, and more specifically comparing the South Bronx and Central Brooklyn, often characterized as low- income and high-minority populations with their white counterparts. New York, among other urban centers in the United States serves as an example of environmental racism because of the discrepancy in high air pollution levels in marginalized communities, the subsequent negative health effects (specifically asthma), and the lack of green spaces. The root of this issue is prominent in the history and construction of New York during the 1900s. The construction …

Arbuscular Mycorrhizal Fungi And Exogenous Glutathione Mitigate Coal Fly Ash (Cfa)-Induced Phytotoxicity In Cfa-Contaminated Soil, Olushola M. Awoyemi, Ekundayo O. Adeleke, Kudjo E. Dzantor
Agricultural and Environmental Sciences Faculty Research
Coal fly ash (CFA) makes a bulk of the coal combustion wastes generated from coal-fired power plants. There are several environmental mishaps due to coal ash spills around the world and in the United States. Management of CFA-polluted sites has proven inefficient resulting in soil infiltration, leaching, and phytotoxicity. This study assessed the mitigation strategies for CFA-induced phytotoxicity using biological [arbuscular mycorrhizal fungi (AMF)] and chemical [exogenous glutathione (GSH)] agents. Indices of phytotoxicity include seed germination, plant morphometrics, lipid peroxidation and genomic double-stranded DNA (dsDNA) in switchgrass plant (Panicum virgatum). Experiments include laboratory screening (0, 5, 10, 15 and 20% …
Climate Change Governance And The Politics Of Scale: Evaluating Local Climate Protection Policies And Practices In The United States And Germany, Ayure-Inga Mark Anthony Agana
Climate Change Governance And The Politics Of Scale: Evaluating Local Climate Protection Policies And Practices In The United States And Germany, Ayure-Inga Mark Anthony Agana
Graduate Theses and Dissertations
When it became evident that the issue of climate change needed to be acted upon, it was projected as a global scale problem. To make this rhetoric concrete, the international relations logic that ‘regimes’ of cooperating nation-states are the most feasible approach to solving problems that are global in nature was adopted. While the national level has performed poorly in climate change mitigation action, as exemplified by the United States’ refusal to ratify the Kyoto Protocol, Canada’s subsequent withdrawal from the Kyoto Protocol in 2011 after initial ratification and, more recently, the United States withdrawal from the Paris Accord, a …

Landuse And Soil Property Effects On Infiltration And Soil Aggregate Stability In The Lower Mississippi River Valley, Rebecca Lynn Anderson
Graduate Theses and Dissertations
Following European settlement of the Lower Mississippi River Valley (LMRV), agricultural expansion and unsustainable, agriculturally related practices have caused groundwater depletion, soil erosion, and surface water contamination by eroded sediments and sediment-bound nutrients to become major environmental threats to the region. The objective of this study was to evaluate the effects of common landuses [i.e., native prairie, deciduous forest, coniferous forest, Conservation Reserve Program (CRP) grassland, and conventional-tillage (CT) and no-tillage (NT) agriculture] on surface water infiltration and aggregate-stability-related properties [i.e., water-stable macroaggregate (WSA) size distribution, total water-stable macroaggregate (TWSA) concentration, and mean weight diameter (MWD)]. The overall infiltration rate …
Strategic Analysis Of New Jersey's Lsrp Program By Applying A Combined Swot-Ahp Technique, Robert Oleksy
Strategic Analysis Of New Jersey's Lsrp Program By Applying A Combined Swot-Ahp Technique, Robert Oleksy
Sigma Xi Student Research Symposium
In 2009 the Site Remediation Reform Act (SRRA) was established which created the Licensed Site Remediation Professions (LSRP) program. LSRPs can provide remediation services without delayed approval from the New Jersey Department of Environmental Protection (NJDEP). The result allows for prompt development of contaminated sites. Ten years after its passage, SRRA 2.0 will soon be introduced. To assist in its strategic development, a modified Strength, Weakness, Opportunities and Threats - Analytical Hierarch Process (SWOT-AHP) will be applied to four stockholder groups to determine each groups' preferences of the current LSRP program. The four groups include government/legal entities, business/trade organizations, non-government …

Hour-Level Resolution On Consumption Pattern Of Substance Abuse, Jarrett Mauk, Rhiannon Huffines, Brittney Nelson, Tara Croft, Bikram Subedi
Scholars Week
Conventional survey-based approaches of determining the consumption statistics of drugs in communities are suffered from non-response biases, and typically underestimate the actual consumption. Time and cost-intensive conventional approaches, therefore, can’t be utilized to determine high-resolution temporal variability in drug consumption. In this study, the temporal trend of consumption of 10 illicit and 26 prescribed neuropsychiatric drugs was determined at hour-level resolution utilizing wastewater-based epidemiology. The hourly composite raw wastewater (every 10 minutes) samples were collected for three consecutive days in a typical week (total of 72 samples), analyzed for target drug residues using UPLC-MS/MS, and back-calculated the consumption rate of …

Monitoring Lesser Known Harmful Algal Blooms On The Oregon Coast, Taylor Dodrill, Tawnya D. Peterson, Matthew Hunter, Micah Rogers
OHSU-PSU School of Public Health Annual Conference
Ocean warming has expanded the niche of harmful algal blooms (HABs), including HABs previously believed to pose little risk of shellfish contamination in the Pacific Northwest. Monitoring efforts in Washington and California have demonstrated that Dinophysis spp. is a HAB of emerging concern and has been linked to diarrhetic shellfish poisoning events. However, quantitative monitoring for Dinophysis spp. on the Oregon Coast has been limited. This analysis provides a preliminary characterization of risk that Dinophysis spp. poses to shellfish consumers in Oregon. Furthermore, we assess the predator-prey interaction between Dinophysis spp. and its prey, Mesodinium rubrum, to determine whether …
Fluoride Removal From Water Using A 3d Printed Calcium Carbonate Filter, Sophia Bakar, David Kahler, Benjamin S. Goldschmidt
Fluoride Removal From Water Using A 3d Printed Calcium Carbonate Filter, Sophia Bakar, David Kahler, Benjamin S. Goldschmidt
Undergraduate Research and Scholarship Symposium
Groundwater containing high concentrations of fluoride is the most common source of drinking water in rural areas in parts of east Africa, India, and China. The elevated levels of fluoride cause skeletal and dental fluorosis, which is the weakening and decay of bone structures due to the leeching of calcium from the body as calcium and fluoride bond by the process of adsorption. Over 150 million people are suffering from some form of fluorosis due to the consumption of groundwater. Calcium carbonate has been demonstrated to influence fluoride removal in several forms. To make fluoride removal a cost-effective and user-friendly …

Total Mercury Accumulation And Spatial Distribution In Beachland Park Pond, West Hartford, Ct And Keney Park Pond, Hartford, Ct, Shane Mark Mclaughlin
Senior Theses and Projects
Ponds are ecologically important as centers for biodiversity, and those within urbanized watersheds typically have altered hydrology, morphology, and water chemistry. The accumulation of heavy metals, such as mercury (Hg), in subaqueous pond sediments has the potential to harm pond ecosystems, but the behavior of Hg in urban ponds is poorly understood. I investigated spatial variability of mercury accumulation within the sediments of two urban ponds: Beachland Park Pond in West Hartford, CT, USA, and Keney Park Pond, in Hartford, CT, USA. I collected 5 samples from 14 distinct sites around each pond’s perimeter. I analyzed the fine (<63 >μm) …63>
Movement For A Gasfield Free Northern Rivers And Its Applicability To Other Movements, Mariah Thomson
Movement For A Gasfield Free Northern Rivers And Its Applicability To Other Movements, Mariah Thomson
Independent Study Project (ISP) Collection
The Gasfield Free Northern Rivers campaign evolved into a broader social movement opposing unconventional gas extraction in the Northern Rivers, New South Wales, Australia. This movement manifested the Bentley blockade in which thousands of people collaborated to resist the invasive gas industry. This movement was successful in getting all gas exploration licenses in the region bought back by the NSW government, thus achieving the goal of keeping the Northern Rivers Gasfield Free. In this study I investigate how the GFNR campaign reached the scale of the Bentley blockade, and what aspects of this campaign and the broader movement are applicable …
The Disparity Between Scientific Consensus And American Public Opinion Of Genetically Modified Organisms And Genetic Engineering, Matthew A. Cherubino
The Disparity Between Scientific Consensus And American Public Opinion Of Genetically Modified Organisms And Genetic Engineering, Matthew A. Cherubino
Student Publications
Genetically modified organisms (GMOs) and genetic engineering (GE) are accepted as safe and useful by the consensus of the scientific community. Their diverse utility has shown promise in addressing major challenges of the 21st century, including world hunger, global warming, and the prevalence of diet-related diseases (e.g. heart disease, cancer, diabetes, etc.). A 2014 Pew Research Center survey revealed that while 88% of scientists agreed that GM foods were safe to eat, only 37% of American consumers agreed. Furthermore, only 35% of U.S. adults trusted scientists to accurately inform the public about GMOs. To explain this disparity, I synthesize information …

Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Martin
James Madison Undergraduate Research Journal (JMURJ)
This study focuses on the environmental value-action gap of students at James Madison University (JMU) in Harrisonburg, Virginia. An environmental value-action gap occurs when a person has pro-environmental beliefs but does not have congruent actions. Over 1,000 JMU students completed a survey of their residence location, environmental values, and environmental actions. Students’ preservation and utilization values were assessed using a 2-Dimensional Model of Ecological Values (2-MEV), and their frequency of environmental actions was assessed through a series of Likert-scaled statements. It was hypothesized that any value-action gap would be wider in students who resided in off-campus housing compared to students …

Health Sciences and Kinesiology Faculty Articles
Los Angeles County (LAC) low-income communities of color experience uneven asthma rates, evidenced by asthma emergency department visits (AEDV). This has partly been attributed to inequitable exposure to diesel particulate matter (DPM). Promisingly, public parks and open space (PPOS) contribute to DPM mitigation. However, low-income communities of color with limited access to PPOS may be deprived of associated public health benefits. Therefore, this novel study investigates the AEDV, DPM, PPOS nexus to address this public health dilemma and inform public policy in at-risk communities. Optimized Hotspot Analysis was used to examine geographic clustering of AEDVs, DPM, and PPOS at the …
