Whose Woods These Are: Human-Environment Relationships Among Stakeholders Of South Mississippi's Longleaf Pine Ecosystem, Helen Greene Dec 2023

Whose Woods These Are: Human-Environment Relationships Among Stakeholders Of South Mississippi's Longleaf Pine Ecosystem, Helen Greene

Master's Theses

Between 1870 and 1920, the longleaf pine belt of the southeastern United States experienced an extensive and unsustainable period of logging. In the years after the logging boom the landscape of the Southeast was reforested, but fire suppression and a preference among landowners for loblolly pine resulted in a dense and less resilient forest with reduced biodiversity. This research looks at the human geography of remnants of the longleaf pine ecosystem in South Mississippi and the nature of contemporary relationships between South Mississippi residents and this ecosystem.

In an effort to make sense of the complex relationships between people and …


New Insights Into The Paleovegetation Of The Ancient Underwater Forest Located In The Northern Gulf Of Mexico, Karla Lizarraga Garcia May 2023

New Insights Into The Paleovegetation Of The Ancient Underwater Forest Located In The Northern Gulf Of Mexico, Karla Lizarraga Garcia

Master's Theses

A well-preserved remnant of an ancient bald cypress forest (hereafter, Underwater Forest) constitutes the only known archive of a glacial refuge on the once exposed continental shelf of the Northern Gulf of Mexico. This forest existed around 41-72 yBP (MIS 3-5) according to the existing dating methods applied on previous studies. As the climate conditions and sea levels changed, the vegetation of this glacial refuge shifted from bald cypress forests to open marshes, altering the vegetation dynamics. The present research analyzed four new cores (21DF-5A, 21DF-5B, 15DF-6, and 16DF-3A), which provided additional insights into the vegetation that once existed in …


Reflections On A Career Unplanned, Robert A. Glazer Jan 2023

Reflections On A Career Unplanned, Robert A. Glazer

Gulf and Caribbean Research

Sometimes life takes unexpected turns. I never planned to be a marine biologist; yet, after a long and unpredictable journey, that’s exactly where I found myself. After obtaining my B.S. in Fishery Biology from Colorado State University, I found myself meandering from job to job like a golden retriever following some vague scent. At first, I was hired by the Wyoming Game and Fish Department to work seasonally in Grand Teton National Park on the freshwater trout fisheries. Soon thereafter, I found myself cultivating oysters, clams, and other shellfish in California. The skills I developed there as an algologist led …


Impacts Of The Poultry Industry In Mississippi, Sara Watts Dec 2022

Impacts Of The Poultry Industry In Mississippi, Sara Watts

Master's Theses

This thesis examines the impacts of the poultry industry in seven counties in the Piney Woods region of South Mississippi: Wayne, Jones, Forrest, Lamar, Jefferson Davis, Marion, and Pike. Current research indicates that the poultry industry has a significant impact on the cultures and economies of rural towns throughout the United States. There is no current research that examines the effects of the poultry industry on residents of the Piney Woods.

Tropical Cyclone Storm Surge Detection In Slash Pine Radial Growth Along The Northern Gulf Of Mexico Coastline, Alyssa C. Crowell Jul 2022

Tropical Cyclone Storm Surge Detection In Slash Pine Radial Growth Along The Northern Gulf Of Mexico Coastline, Alyssa C. Crowell

Master's Theses

My thesis examines the ecological impact of tropical cyclone (TCs) storm surge on coastal slash pine (Pinus elliottii var. elliottii Engelm) communities along the Gulf of Mexico in the southern United States (U.S.). Previous research has shown slash pine radial growth trends can be examined to identify long and short-term growth changes associated with TC passage, providing insight into overall stand health and resiliency through time. However, this previous research encompasses just one site in Mississippi. My thesis expands the spatial footprint of TC-surge impact on slash pine radial growth with the addition of three new sites.

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich May 2022

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed …

Faculty Publications

The geostationary ocean color imager (GOCI), as the world’s first operational geostationary ocean color sensor, is aiming at monitoring short-term and small-scale changes of waters over the northwestern Pacific Ocean. Before assessing its capability of detecting subdiurnal changes of seawater properties, a fundamental understanding of the uncertainties of normalized water-leaving radiance (nLw) products introduced by atmospheric correction algorithms is necessarily required. This paper presents the uncertainties by accessing GOCI-derived nLw products generated by two commonly used operational atmospheric algorithms, the Korea Ocean Satellite Center (KOSC) standard atmospheric algorithm adopted in GOCI Data Processing System (GDPS) and the NASA standard atmospheric …


No More Shade: Deforestation And Rural-Urban Migration In Nigeria, Kambre Sims May 2021

No More Shade: Deforestation And Rural-Urban Migration In Nigeria, Kambre Sims

Master's Theses

Some of the most well-documented motivating factors of migration in Nigeria include education, employment opportunities, and cultural conflicts. However, as the deforestation crisis has not improved and Nigeria has maintained its spot as the country with the most deforestation on Earth, access to critical forest resources may be in danger. In light of this crisis, this paper attempts to determine if deforestation has become a new motivating factor for migration as those in rural communities seek other avenues of obtaining those vital resources. Subsequently, Nigeria is also experiencing a housing crisis within its rapidly growing urban centers; obtaining and keeping …

A View From Above: Alternative Perspectives On Smallholder Livelihoods And Agrobiodiversity Conservation In Northern Ecuador, Chris Hair

Dissertations

Food security and deintensification of agriculture are serious concerns in Latin America. Agriculture, especially at small-scale subsistence levels, is hard work, and comes with some economic and physical risk. Transitions from traditional multi-cropping to mono-cropping systems introduce two particular risks that are new to most smallholders: (1) the loss of agricultural diversity and (2) the potential for widespread failure when focusing on the cultivation of a single crop. This research explores how Small Unmanned Aerial Systems (sUAS), or drones, can be used for rapid inventories of crop diversity and to enhance crop management techniques on small-scale farms. In the community …

Geographical Analysis Of Offender Vulnerability: Modeling Coastal Hazards And Social Disorganization In Southern Mississippi, Ashleigh Nicole Price May 2019

Geographical Analysis Of Offender Vulnerability: Modeling Coastal Hazards And Social Disorganization In Southern Mississippi, Ashleigh Nicole Price

Master's Theses

Hazards research continually examines how specific groups are affected by damaging events and how their unique sociodemographic characteristics contribute to variations in resilience and recovery. Studies have shown that underprivileged communities suffer more adversely and take longer to recover from hazard events. Probationers and parolees are uniquely disadvantaged regarding demographics and economic opportunity, both of which contribute to increased vulnerability and reduced resilience. Numerous legal restrictions and widespread discrimination towards former criminals means offenders are often relegated to underserved, criminogenic neighborhoods. Given such severe social and financial limitations, offenders have little capacity to prepare for or recover from disasters.

Detecting Coastal Marsh Change From Aerial Imagery Using Spectral And Textural Methods: Pascagoula River Estuary, Mississippi, 1955-2014, Margaret Claire Bell Waldron

Master's Theses

As sea level rise accelerates, coastal marsh ecosystems are increasingly vulnerable. Vertical accretion rates must exceed or keep pace with rates of sea level rise to prevent transition to open water or inland migration of marsh vegetation. While some marsh systems along the northern Gulf of Mexico coast have remained stable, others, e.g., the marshes of the Louisiana Gulf Coast, have experienced high rates of conversion to open water. This study examined the historical extent of intertidal marsh at the mouth of the Pascagoula River in Jackson County, Mississippi to determine whether marsh extent changed during the period 1955-2014 and …


Hope For Struggling School Districts, Mary D. Travis May 2019

Hope For Struggling School Districts, Mary D. Travis

Master's Theses

Education improves the opportunities and life-chance outcomes of our children, and is a key factory in both economic and community development. Although high school graduation rates have shown improvement nationwide in recent years, public education is suffering from increasing inequality between different school districts and within the same school districts. Such inequalities widen academic outcome gaps and can result in entire school districts being branded as academic failures. However, there is also encouraging evidence of struggling schools and school districts moving toward improvement. Innovative leaders who are committed to inclusive and rigorous academics, shared leadership, and an in-depth understanding of …

The Rebel Made Me Do It: Mascots, Race, And The Lost Cause, Patrick Smith Apr 2019

The Rebel Made Me Do It: Mascots, Race, And The Lost Cause, Patrick Smith

Dissertations

Public memory is commonly tied to street names, toponyms, and monuments because they are interacted with daily and are often directly associated with race, class, and regimes of power. Mascots are not thought of in the same manner although they are present as part of everyday life. The childish or sometimes comedic nature of the mascot discounts it from many considerations of its influence, symbolism and history. Nonetheless this research focuses on the term “Rebel” as a secondary school mascot. The term possesses the trappings of race because the American vernacular ties the word to the Confederate States of America …
