Assessing The Threat Of Coral Decline On Fish Diversity In Response To Temperature, Ryland Talmadge
Independent Study Project (ISP) Collection
Misali, a PECCA-protected island off the east coast of Pemba, Tanzania, is considered to be a marine biodiversity hotspot with a protected Non-Extractive Zone (NEZ) and remaining Extractive Zone (EZ). Upon protection, the island’s fringe reefs faced severe coral bleaching during the 1998 bleaching event, estimated to kill up to 70% of corals. Since the event, several others have occurred in addition to restructuring the management plan in 2006 to expand the region to 1000km. While the damage from the most recent coral bleaching event in 2020 has yet to be surveyed, this study investigates the current reef health in …
Sacred Scavengers: Vulture Conservation In Nepal, Hans Nedde
Sacred Scavengers: Vulture Conservation In Nepal, Hans Nedde
Independent Study Project (ISP) Collection
In the 1990s, a veterinary drug used to treat pain and disease in cattle nearly brought the nine vulture species of Nepal to extinction. In a span of 15 years, over 97% of vultures in Nepal perished. For the past 20 years, governments, organizations, and communities have been working together to save these vital scavengers from vanishing. From the lowlands to the Himalayas, vultures have been interacting with the environment and humans for millennia. This study explores the role that vultures play both ecologically and culturally in Nepal. It investigates vultures as a crucial ecological influence and how human action …

Energy Literacy In Portugal: A System Map And Framework To Increase Energy Literacy Through The Renewable Energy Transition, Molly S. Fox
Independent Study Project (ISP) Collection
Western society lives with a great dependence and an almost simultaneous ignorance of energy consumption (van den Broek, 2019). The systemic landscape of energy knowledge and dissemination is more critical than ever as Portugal races to meet decarbonization goals. This paper fills a knowledge gap by updating the current social landscape of energy literacy in Portugal through a comprehensive system map and framework to increase energy literacy levels through the renewable energy transition. By conducting a semi-systematic literature review, meta-narratives and themes were identified and used to create theoretical concepts, a framework, and a system map. This research found that …

Independent Study Project (ISP) Collection
The objective of this research was to learn about Isla Narganá and Isla Corazón de Jesús, Comarca Guna Yala residents’ perspectives on climate change and, to learn about what needs to be done to mitigate the effects of climate change on the islands. In April 2022, eighteen semi-structured interviews were conducted in Spanish with residents of the islands. Interviews revealed that flooding caused by sea level rise, intensification of precipitation events, extreme heat, and biodiversity loss were the most reported impacts of climate change on participants’ lives. Poor waste management opportunities were also discussed as a critical environmental issue affecting …
Comparing Amphibian Species Diversity And Abundance In Natural Forest And Cacao Agroforest At Finca La Magnita, Changuinola, Bocas Del Toro, Panamá, Lake Barrett
Independent Study Project (ISP) Collection
Amphibians are currently undergoing rapid and drastic biodiversity loss worldwide, largely due to the disease Chytridiomycosis. Because of this, efforts to conserve amphibian biodiversity are urgent and have been given increasing importance. However, studies investigating the effectiveness of agroforestry systems, a commonly used agricultural method in which trees and other elements of forests are retained on land used for agriculture, for amphibian conservation are uncommon. As a result, the capacity of agroforests to serve as a tool for amphibian conservation is unclear. To determine if agroforests can serve as a habitat for amphibians and a tool for their conservation, this …

Development And Assessment Of An Environmental Dna (Edna) Assay For A Cryptic Siren (Amphibia: Sirenidae), Krista M. Ruppert, Drew R. Davis, Md Saydur Rahman, Richard J. Kline
School of Earth, Environmental, & Marine Sciences Faculty Publications
Environmental DNA (eDNA) assays have become a major aspect of surveys for aquatic organisms in the past decade. These methods are highly sensitive, making them well-suited for monitoring rare and cryptic species. Current efforts to study the Rio Grande Siren in southern Texas have been hampered due to the cryptic nature of these aquatic salamanders. Arid conditions further add to the difficulty in studying this species, as many water bodies they inhabit are ephemeral, sometimes constraining sampling efforts to a short window after heavy rain. Additionally, sirens are known to cease activity and reside underground when ponds begin to dry …

School of Earth, Environmental, & Marine Sciences Faculty Publications
Aggregate and limestone mining in San Antonio's Bexar and Comal counties in Texas, USA, has caused considerable health concerns as of late. Aggregate mining actions can result in localized air quality issues in any neighborhood. Furthermore, heavy truck traffic, hauling, and transportation of the mined material contribute to pollution. In this research, PM species were sampled at four locations north of the San Antonio city limits. The data were collected using a TSI Air Quality Sampler that sampled PM1, PM2.5, PM4, PM10, wind speed, wind direction, temperature, and relative humidity. Continuous data with 1 min averages were recorded during the …

Protecting Terrapins With Teds In Virginia: Lessons From Other States, Bridget Verrekia, Shelby Fuchs
Virginia Coastal Policy Center
This paper highlights case studies about other states' efforts to require or incentivize the use of TEDs [terrapin excluder devices] and recommends policies for Virginia to adopt that have proven successful elsewhere. First, it outlines the threats to terrapins at large, as well as the threat posed by commercial and recreational crabbing, specifically. Next, it details the efforts that other East Coast states have made to combat the problem, including policies that require or incentivize the use of TEDs on crab pots, and discusses the regulatory framework currently in place in Virginia. Finally, this paper concludes by analyzing the approaches …
Building For The Future: Functional, Energy-Efficient, And Beautiful Buildings By Snøhetta, Amanda J. Oross
Building For The Future: Functional, Energy-Efficient, And Beautiful Buildings By Snøhetta, Amanda J. Oross
Student Publications
The construction industry accounts for nearly 40% of all greenhouse gas emissions, which ultimately leads to climate change. Because of a lack of global consensus and accountability on a large scale about how to combat climate change, certain countries and cities are leading the charge on mitigation, since they tend to be more progressive and homogenous. Norway is one of those countries, and happens to be the headquarters for Snøhetta, a design company, that is designing buildings that are not only energy-efficient but also functional for the space in which it resides. Snøhetta very much values the interconnection between the …
Evaluating Human Pressure On Protected Areas In East Africa, Bailey M. Ytterdahl
Evaluating Human Pressure On Protected Areas In East Africa, Bailey M. Ytterdahl
Student Publications
Protected areas (PAs) are crucial to achieving effective conservation goals and mitigate the loss of biodiversity. I investigated the following research questions: How does human pressure threaten PAs in East Africa? Is human pressure associated with the factors of country, ecosystem characteristics, size, or governance type of a PA? For this study, I used a combination of a GIS analysis and case studies to evaluate human pressure on PAs in Tanzania and Kenya. For the GIS analysis, I used 589 terrestrial PAs from the World Database on Protected Areas (WDPA). Within each PA, I summarized the landform, landcover, moisture level, …
Ecosystem Service Trade-Offs In Coral Reefs: A Global Analysis, Megan E. Keene
Ecosystem Service Trade-Offs In Coral Reefs: A Global Analysis, Megan E. Keene
Student Publications
Coral reefs are biodiversity hotspots that provide humans with extractive ecosystem services like fisheries and non-extractive services like tourism. Though no studies have examined these trade-offs among these services at a global scale, there are now large, open datasets that make this possible. Using these datasets, we asked whether spatial protection and the level of protection (World Database on Protected Areas) impacted coral reef tourism value (Atlas of Ocean Wealth). We also examined whether proximity to regions of high fishing effort, defined as the top 25th percentile of the average annual effort from Global Fishing Watch, impacted tourism values. Since …

Logging Impacts On Aquatic Ecosystem Quality In Michaux State Forest, Pennsylvania, Sara Baran, Timothy J. Bell, Erick R. Seager
Student Publications
Logging can affect freshwater streams around logging sites, even years after the logging has occurred. In this study, we looked into how sustainable logging in Michaux State Forest (in Adams County, Pennsylvania) has affected two streams within the state park: Mountain Creek and Birch Run. Six sites were selected along each stream, with three upstream and three downstream from the logging area. We hypothesized that the water quality would be lower at the stream sites downstream from the logged areas as compared to the upstream sites. At each site, water samples were collected, including pH, water temperature, and turbidity, as …

Sea Level Rise And Public Perceptions Of Climate Change At Otter Point Creek Estuarine Reserve, Md, Haley A. Bechtel, Meghan L. Junis, Keylen Lucero Garcia
Student Publications
Freshwater tidal marshes are essential stopover points for migratory birds traveling up and down the east coast of North America. Given the importance of these habitats, we examined the effects of sea level rise on vegetation health and vegetation migration at Otter Point Creek Estuarine Reserve. We aimed to test three predictions: 1) vegetation health will decline over time during vegetation growth periods, 2) vegetation migration of less water-tolerant species will occur with movement into higher elevation plots, 3) people will be aware that there are impacts of climate change on species around them and themselves. We used a combination …

Leveraging Land Easements For Grassland Bird Habitat Conservation, Amy N. Marigliano, Hayden E. Dubniczki, Sarah W. Westrick
Student Publications
In addressing the decline of North American grassland bird populations, it is important to consider the various interdisciplinary approaches that can be employed in their conservation. OECMs, or “other effective area-based conservation measures” encompass a wide array of strategies which can be leveraged to conserve natural landscapes and species. Land easements implemented by the Land Conservancy of Adams County (LCAC) are an example of one such strategy. The LCAC seeks primarily to preserve the rural character of Adams County but has more recently turned their focus toward environmental conservation. In partnering with the Land Conservancy, this case study aimed to …
Destruction Is A Must-See: Coastal Heritage Site Erosion And Public Perception Of Climate Change, Haley Borowy
Destruction Is A Must-See: Coastal Heritage Site Erosion And Public Perception Of Climate Change, Haley Borowy
Senior Theses
Archaeological sites in South Carolina are vanishing. As sea level rise, and therefore coastal erosion, worsen, more sites will disappear. The questions of how erosion at these sites is measured and how the public perceives the effects of climate change have been studied separately, but not together. Here, the intersection of these is discussed, alongside how sites are portrayed affects how the public perceives them, and therefore their importance. Studies on measuring coastal erosion, local news reports, government documents, and public perception of coastal management and sea level rise illuminate how people eventually decide what is worth saving.
Why Capacity Market Prices Are Too High, Todd S. Aagaard, Andrew N. Kleit
Why Capacity Market Prices Are Too High, Todd S. Aagaard, Andrew N. Kleit
Faculty Publications
The Federal Energy Regulatory Commission and regional transmission organizations have fixated on a concern that prices in electricity capacity markets are too low. In fact, however, capacity markets are significantly overpriced. The reason for this is that the administratively determined demand curves in capacity markets create conditions that procure far more electricity capacity than what is needed to meet reliability objectives. In particular, the operators of these markets systematically overestimate both the relevant peak demand for electricity and needed payments for generators to enter the market. The result is that consumer pay billions of dollars extra for excess capacity.

Atmospheric water harvesting (AWH) has been an appealing prospect for decades to overcome water scarcity in remote areas. Adsorption-based AWH technologies have gained popularity due to their adaptability, and applicability using low-grade heat sources. This study presents up-to-date and future possibilities of adsorbents and systems for adsorption-based AWH. In this review, in-depth advancements in adsorbent materials are compartmentalized into adsorption equilibrium/isotherms, adsorption kinetics, and thermal conductivity. Various systems designs and modifications have been reviewed and classified accordingly. Liquid desiccants i.e., CaCl2 and LiCl-based AWH systems produced in between 0.63 to 1.0 kg/m/d of water. Recently, metal-organic frameworks …
