Where's Our Water? Invasive Saltcedar's Thirsty Trek Across The Shoreline Of Lake Mead, Mia R. Morgan, Joseph Penrod, Ruth Kerry

FHSS Mentored Research Conference

The prolonged megadrought in Southern Nevada has exposed thousands of acres of former lakebed at Lake Mead, creating an expanding frontier for the invasive shrub Tamarix ramosissima, commonly known as saltcedar. This hardy, non-native species rapidly colonizes the receding shoreline, siphoning up to 200 gallons of water per plant daily and outcompeting native vegetation. Utilizing high-resolution satellite imagery from 2020 and 2025, this research found that saltcedar coverage within a 5 km radius of the lake increased by approximately 76.7%.

Analysis of the spatial data indicates that while the total area of infestation has exploded, the average distance of …

Finding Belonging In A Religious Dominant Society: Religion Among African Migrants In Türkiye, Garrett L. Wride, Stacey A. Shaw

FHSS Mentored Research Conference

As global migration increases each year, so does the need to understand the crossroads between inclusion, wellbeing, and religion. The experience of African migrants living in Türkiye presents itself as a unique case to study migrant wellbeing. Using quantitative and qualitative analysis, this study shows that African migrants in Türkiye belonging to the religious minority have lower scores of wellbeing and social support. Findings point to the need for policy makers and mental health practitioners to ensure migrants can access their religious communities.

Organizing To Engage: A Framework For Conflict Strategy, Paul Mason Carpenter

Dissertations

Conflict strategy can be exceedingly complex. While many of the basics are simple, even the simple can be highly complicated to execute. The Schlieffen Plan in World War I appeared straight forward, but execution was a great deal more complex. It failed and the result was years of trench warfare.  In addition, leaders entering conflict may not fully appreciate the full context, its effect, and the need for a long term result--a better state of peace.

Strategy and tactics may be challenging to transform as an engagement evolves. In addition, strategists must often commit to courses of action within very …

Workforce Dynamics In Michigan's Upper Peninsula: Trends, Shocks, And Projections Through 2030, Iryna V. Lendel

Presentations

Michigan’s Upper Peninsula is navigating a complex economic transition shaped by demographic change, workforce aging, and sectoral concentration. While the region has experienced long-term population decline, its labor force has remained stable due to rising participation among older workers. At the same time, the U.P.’s economy remains highly concentrated in extraction, construction, and production industries. These industries offer strong wages but are sensitive to economic cycles.

This presentation highlights key findings on workforce structure, industry specialization, and the region’s capacity to respond to potential shocks, including major employer closures. Evidence shows substantial skill overlap across industries, creating opportunities for worker …

The first essay investigates the geographic determinants of impact investments, assessing whether they flow to communities with lower economic connectedness—a proxy for economic mobility. It further explores how the location and type of co-investors influence investment characteristics, investor monitoring, and exit outcomes, shedding light on how traditional and impact investors interact and shape investment outcomes. The second essay examines the role of SWFs in impact investing. It analyzes the channels through which SWFs deploy impact …

Amphibole Reaction Rims Record Shear During Magma Ascent, Paul A. Wallace, Janine Birnbaum, Sarah H. De Angelis, Elisabetta Mariani, Jessica Larsen, Jackie E. Kendrick, Thomas E. Christopher, Paul D. Cole, Anthony Lamur, Yan Lavallée

School of Geography, Earth and Environmental Sciences

Mineral reaction textures are fundamental archives of geological change. Amphibole reaction rims are among the most widely used to reconstruct pre-eruptive magmatic conditions, traditionally interpreted through changes in pressure, temperature and melt composition. However, these interpretations have largely overlooked the role of deformation, ubiquitous during magma ascent. Here we show that amphibole breakdown is not only thermodynamically sensitive, but also mechanically sensitive. Using electron backscatter diffraction (EBSD) analyses of experimental and natural samples, combined with numerical simulations of crystal rotation under magma flow, we demonstrate that pyroxene nucleates topotactically on amphibole, forming rims, but can later reorient in response to …

Long-Term Assessment Of Cattail (Typha Spp.) Dynamics And Wetland Restoration In The Everglades Using Object-Based Landsat Time Series And Markov Modeling, Gideon Tandoh, Stephen Yankyera, Michael Sean Chenoweth

Research, Publications & Creative Work

Assessing long-term vegetation response to restoration requires spatially consistent monitoring approaches that capture both observed change and likely future trajectories. In the Florida Everglades, nutrient enrichment contributed to the expansion of cattail (Typha spp.) within Water Conservation Area 3A (WCA-3A), raising concerns about restoration effectiveness. This study integrates a multi-temporal Landsat time series (2004–2024), object-based image analysis (OBIA), support vector machine (SVM) classification, and Markov transition modeling to quantify and project vegetation change in WCA-3A. Object-based segmentation reduced classification fragmentation in heterogeneous marsh landscapes, while SVM improved separation among spectrally similar vegetation classes. Classification accuracies remained consistently high across sensors …
