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 …

Larval Fish Abundance In The Benthic And Surface Drift Of The Missouri River, Ryan L. Ruskamp

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

Knowledge of the larval fish community of the Missouri River is one of the biggest gaps in fisheries research. The Nebraska Game and Parks Commission has sampled the drift of the Missouri River for many years (1983-2015), but these data have not been compiled into a unified assessment. Therefore, the objectives of this study were to: 1) quantify temporal and spatial aspects of larval fish community composition (richness) and structure (abundance) of the surface drift, 2) quantify associations of larval fish communities of the drift to different discharges of the Missouri River, 3) quantify the larval benthic drift community, and …

A Mixed Methods Case Study: Effects Of Instructors’ Beliefs On Incorporation Of Sustainability Curriculum At A Midwestern University, Anna Oetting

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

The degree to which sustainability is taught is often varied and inconsistent across colleges, departments, and higher education institutions. However, educating students and future generations regarding the different pillars of sustainability, including economic, social, and environmental topics, is increasing in importance and urgency. A mixed methods case study utilized surveys and interviews to investigate why instructors incorporate sustainability, what impacts course incorporation of sustainability, and barriers that instructors face. This study found that instructors’ beliefs regarding the importance of sustainability relate to the extent to which sustainability is incorporated into their curriculum. Topics of sustainability incorporated into a class are …

Stuck In The Net: Promoting Global Shark And Ray Populations Through National Sustainability Import Laws, Kelsey Peden

William & Mary Environmental Law and Policy Review

Shark and ray populations are crucial to a healthy oceanic ecosystem, but regulation of harm is difficult to manage for these highly migratory species. The massive decline of shark and ray populations has triggered an international response, including collaborative protections against the overharvest and sale of endangered groups. However, recent studies show that protections must extend past direct harvest because an estimated thirty to fifty percent of population kills occur through “accidental by-catch” in the fishing process. The United States has attempted to fill some of the missing protections for sharks in national waters, as well as to implement bans …

Casting Pearls Before Swine: Why The Public's Darling Right To Pollute Should Have Been Overturned In Recent Scova Decision, Thummim Park

William & Mary Environmental Law and Policy Review

This Note calls for the Virginia Supreme Court to recognize that a city’s right to freely pollute the public waterways is no longer valid under the Virginia Constitution, and to recognize that the line of Darling cases granting municipalities the public right to pollute waterways should have been overturned.

Part I will set out the foundation for this Note. It will discuss the background of Johnson v. City of Suffolk, laying the context for this Note’s discussion. Part II will engage in an analysis of the rationale for Darling. It will contextualize and compare it to current understandings …

Encouraging Sustainable Innovation: Is There Room For A Post-Grant Environmental Challenge In American Patent Law?, Samuel Habein

William & Mary Environmental Law and Policy Review

This Note examines potential changes within the American patenting system that might renew the U.S. Patent and Trademark Office’s (“USPTO”) dedication to the promotion of progress through a post-grant environmental challenge to patents. There are many ways to encourage “green” innovation by challenging practices that harm the environment, but the patent system has a unique ability to discourage environmentally harmful innovation by refusing to grant exclusionary rights—rights that many industries require to thrive. However, a post-grant environmental challenge would undoubtedly disrupt the American patent system in severe ways that this Note does not address. Therefore, this Note is not arguing …

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 …

Economic Consequences Of The Wolf Comeback In The Western United States, Dana Hoag, Stewart W. Breck, Kevin Crooks, Becky Niemiec

United States Department of Agriculture Wildlife Services: Staff Publications

Gray wolves were eradicated from most of the United States in the 1940’s but have made a comeback in parts of their historic range over the last two decades. First reintroduced into the Greater Yellowstone Ecosystem and central Idaho in the mid-1990’s, wolves have subsequently dispersed into at least 7 western states. Coloradoans became the latest state to take interest in bolstering wolf populations, as residents passed a ballot initiative in November 2020 to reintroduce a self-sustaining population of gray wolves by the end of 2023. Conflicts between people in rural areas that might incur costs (such as livestock loss) …

Nm Stat § 7-36-20: Disconnected Land And Water Policy In A Climate-Altered Peri-Urban Fringe, Annalise Porter

Water Resources Professional Project Reports

New Mexico (NM) passed a land use law in 1967 that offers tax subsidies to agricultural landowners and is implemented at the county level. This law illustrates a stark disconnect between land and water policy: there are water policy implications because of it, but it has never been discussed accordingly. With a focus on New Mexico’s primary urban county, this study estimates that in 2020, Rio Grande surface flows were used to irrigate 4,388 acres of Bernalillo County land that received the special tax valuation offered through the law. This represents a potential use of nearly 11,000 acre-feet of water, …

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 …

Protected areas are intended as tools in reducing threats to wildlife and preserving habitat for their long-term population persistence. Studies on ranging behavior provide insight into the utility of protected areas. Vultures are one of the fastest declining groups of birds globally and are popular subjects for telemetry studies, but continent-wide studies are lacking. To address how vultures use space and identify the areas and location of possible vulture safe zones, we assess home range size and their overlap with protected areas by species, age, breeding status, season, and region using a large continent-wide telemetry datasets that includes 163 individuals …

European Starling Use Of Nest Boxes Relative To Human Disturbance, Bradley Blackwell, Bruce N. Buckingham, Morgan B. Pfeiffer

United States Department of Agriculture Wildlife Services: Staff Publications

gars and to engine and flight surfaces of moored aircraft. We questioned whether consistent removal of nest material would negatively affect use of a nest site, measured by a reduction in material accumulation. We conducted our study on a 2,200-ha site in Erie County, Ohio, USA (41° 22’ N, 82° 41’ W), from April 15 through June 2, 2020. We used 120 wooden nest boxes on utility poles, protected by an aluminum predator guard below the box. Our treatments included (1) twice weekly, repeated nest material removal (RMR; n = 40 nest boxes); (2) complete nest removal, but only after …

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 …

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 …

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 Of Enhanced Algae Strains And Sustainable Cultivation Processes For Production Of Algal Lipids For Biofuels And Bioproducts, Enlin Lo

USF Tampa Graduate Theses and Dissertations

The establishment of an algae industry is crucial for addressing global biofuel and bioproduct demand that meets the Sustainable Development Goals (SDG) worldwide. Photosynthetic microalgae are excellent sources for food, fiber, fuel, feed, and fertilizer, which are the 5Fs of the SDG. However, at present, algae-based materials are not cost-competitive or sufficiently sustainable. Improved productivity, lower cultivation cost, and reduced use of resources are required to transition from lab to industry, necessitating the development of superior strains that have high productivity and can tolerate environmental stress, such as temperature and salinity, so they can be cultivated at large scale outdoors …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Peru has shifted away from centralized mining management to governance among government, companies, and communities. Various mechanisms facilitate community participation, including the mining canon, dialogues, and corporate social responsibility programs. Even with these laws and mechanisms, mining pollution and conflicts continue. In this study, we ask: how do communities perceive and participate in mining governance? And what are some alternative ways, driven by community priorities, to address governance in mining contexts? We collected 53 semi-structured with agricultural actors in two Peruvian districts with mining activity and analyzed those perspectives through the lens of community-centered governance. Our analyses revealed how centering …

Geothermal Development In Kenya: Gender Based Socio-Cultural And Socio-Economic Implications, Faye N. Ricker

USF Tampa Graduate Theses and Dissertations

This dissertation is an ethnographic case study that analyzes the gendered socio-cultural and socio-economic implications for a community that was displaced in order to develop a geothermal energy system in Kenya. The implications are rendered particularly interesting because the displaced community is also one of the communities served by the geothermal power grid. The analysis employs a composite framework of Feminist Political Ecology and the Political Ecology of Climate Change Mitigation. This work explores gendered perceptions and control of energy, livelihood activities, place attachment, and the cultural/spiritual significance of geothermal energy.

Geothermal energy is a potentially promising source of low-carbon …

A Statistical Method For Quantifying Animal Interaction; Combining Time Geography And Simulation, Zachary J. Smith

USF Tampa Graduate Theses and Dissertations

Dynamic interaction (DI) describes the synchronous interaction of one or more individual animals over time. Current methods to quantify DI from tracking data are lacking. They typically require synchronized tracking data which limits their applicability to most studies. They also often do not have built-in tests of significance to evaluate interaction, and if so, rely on random walk models that lack biological realism. This research aimed to develop and evaluate a new way of measuring animal interaction that overcomes these limitations. The goal was to create a statistical method for quantifying and evaluating interaction that is relevant across computational, behavioural, …

Chemical And Carbon Isotopic Characterization Of A Karst-Dominated Urbanized Watershed: Case Of The Upper San Antonio River, Abongwa T. Pride, Walter Den, Aarin Teague

Water Resources Science and Technology Faculty Publications (Archived)

Urbanization and agriculture are two key factors that place demands on water resources and serve as sources of anthropogenic pollution into inland waterways. The San Antonio River, which is sourced from a karst aquifer, plays an important recreational and scenic role, yet effective management is often hampered by the lack of understanding of the chemical characterization of the water system. The karst-dominated Edwards Aquifer watershed in south-central Texas is an ideal watershed to understand water-rock interaction (carbonate dissolution) and anthropogenic impact on our water resources. In order to understand groundwater-surface water interactions, we made chemical and isotopic measurements over a …
