Safe Water For All: A Multi-Modal Approach To North Alabama's Water Resources, Elijah Walker
Safe Water For All: A Multi-Modal Approach To North Alabama's Water Resources, Elijah Walker
Theses
Environmental degradation is a destructive force produced by the human disturbance of pollution. It is a phenomenon that gradually evolves landscapes over time resulting in irreversible outcomes. Environmental degradation physically affects spaces’ resources, objects, and inhabiting humans. This study observes the impacts of pollution beyond physical boundaries and how it affects human identity/sense of place through the utilization of geographic information systems. Specifically, it examines cultural identity developed through human experiences and connections to landscapes containing water resources. Following, pollution contaminates water resources disrupting experiences and connections thus causing the cultural identity to disappear. The case study applied to this …
Defining The Leading Edge Of The Marine – Non-Marine Transition In The Pee Dee Basin: Influences, And Dynamic Parameters Of A Highly Dynamic System, Nicole Mchugh
Honors Theses
Among estuaries, there is a large block of co-dependent and independent variables shaping habitat and environmental conditions within a critical area. Historical data proxies and indexes from seven different stations were assessed to consider temporal and spatial variability of the marine and non-marine transition along the South Carolina Pee Dee River Basin. Historical datasets from the upper reaches of Winyah Bay and lower section of the Pee Dee River basin were compiled along with shorter termed deployments of a new instrument station installed near Georgetown, SC. This area is representative of the marine-non-marine transition in drowned river mouth estuaries. Water …
The Battle For The Sea: Tourism Development And Public Ocean Access In Jambiani, Zanzibar, Sophie Beauchesne
The Battle For The Sea: Tourism Development And Public Ocean Access In Jambiani, Zanzibar, Sophie Beauchesne
Independent Study Project (ISP) Collection
The battle for coastal access is a prevalent and controversial issue in both the Global North and the Global South (Mongeau, 2001; Ojo, 2013). Due to investment in coastal land, vulnerable communities around the world are losing their access to the sea (Ojo, 2013; Bennett, Govan & Satterfield, 2015). Battles for ocean access in the Global North tend to focus on recreational activities, but what is to be said about ocean access in the Global South, where access to the sea is needed for the survival of entire communities? (Mongeau, 2001;). Using geographical mapping, environmental condition assessments and open-ended interviews …

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 …

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 …

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 …
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 …

Global pest invasions have significantly increased in recent years. These invasions together with climate warming directly impact agriculture. Tropical climates feature extreme weather events, including high temperatures and seasonal droughts. Thus, successful invasive pests in tropics have to adapt to these extreme climate features. The intrinsic factors relevant to tropical invasion of insects have been explored in many studies, but the knowledge is rather dispersed in contemporary literature. Here, we reviewed the potential biophysical characters of successful invasive pests’ adaption to tropical environments including [1] inherent high basal stress tolerance and advanced life-history performances [2], phenotypic plasticity [3], rapid evolution …

Climate change and agriculture are strongly correlated, and the fast pace of climate change will have impacts on agroecosystems and crop productivity. This review summarizes potential impacts of rising temperatures and atmospheric CO2 concentrations on insect pest-crop interactions and provides two-way approaches for integrating these impacts into crop models for sustainable pest management strategies designing. Rising temperatures and CO2 levels affect insect physiology, accelerate their metabolism and increase their consumption, ultimately increasing population densities, which result in greater crop injury and damage, and yield loss. Whereas these direct effects are empirically demonstrated for temperature rises, they are less straightforward for …

Despite their important ecological roles for soil health and soil fertility, free-living nematodes (FLN) have received relatively limited research attention. The present study evaluated the community structure and diversity of FLN in a field setting. The experiments were conducted in on-farm and on-station field plots sown to maize (Zea mays) and beans (Phaseolus vulgaris) under four cropping practices. These farming systems included organic (compost and biopesticide use), conventional (synthetic fertilizer and pesticide applications), farmer practice (organic and synthetic amendments) and a control (non-amended plots). Nineteen genera of free living nematodes, belonging to bacterivores, fungivores, omnivores and predators were recorded. Among …
Species Diversity And Barcoding Of Macroinvertebrates From The San Antonio River, Gabrielle Silva
Species Diversity And Barcoding Of Macroinvertebrates From The San Antonio River, Gabrielle Silva
Student Research Symposium 2022 (Archived)
Macroinvertebrates are important biological indicators of health and ecological change within aquatic ecosystems. Macroinvertebrate diversity of the San Antonio (SA) River Watershed (Texas), which traverses rural and urban regions (Bexar County, TX), remains understudied compared to vertebrate counterparts of economic and conservation importance. The SA River hosts a diversity of crustaceans (crayfish), insects (beetles, dragonflies), annelids (leeches), and unidentified larvae at intermediate developmental stages. To improve ecological records of the SA River, an integrative approach is used to establish a reference macroinvertebrate species inventory and a genetic barcoding database (mitochondrial COI and/or 16S rRNA) for the SA River Mission Reach …
