Is Spring Break Coming Early? Effects of Climate Change on Alabama\u27s Native Plant Phenology
Please note: no video is available for this presentation.
Climate change has significantly impacted biodiversity, prompting many species to adapt by altering their phenology—the timing of life cycle events. Shifts in plant phenology can have far-reaching ecological consequences, particularly for species that rely on these plants directly or indirectly. One critical consequence is the temporal mismatch between plants and their pollinators, a phenomenon observed in multiple species. Studies using satellite imagery have documented advances in spring phenology across the United States, but species-specific data remain limited, especially in the biodiverse and ecologically vulnerable Southeastern region.
To address this gap, we analyzed historical records from herbarium specimens of native plant species in Alabama. Our dataset consisted of 1,304 specimens from 11 species, spanning 146 years. The analysis revealed that 10 of the 11 species exhibited advanced flowering phenology, with three showing statistically significant correlations (p \u3c 0.05) between the day of year (DOY) of flowering and the collection year, as determined by Pearson’s correlation.
This study represents the first attempt to leverage herbarium specimens to investigate climate-driven changes in plant phenology in the Southeastern United States. The observed advancements in flowering phenology for most species align with global findings from previous studies. While satellite imagery has highlighted regional trends in spring phenology, its broad spatial scale cannot capture species-specific responses, underscoring the value of our specimen-based approach.
Expanding this research to include more species and specimens would help address key limitations, including the small sample size for certain species.https://digitalcommons.jsu.edu/ce_jsustudentsymp_2025/1052/thumbnail.jp
Fallen Soldiers of Calhoun County: The Stories and the Sacrifice
Please note: no video is available for this presentation.
My presentation is on the stories of Calhoun County soldiers who were killed in the line of duty from WW1 through the Vietnam War. I also include one soldier who survived and is a war hero. I chose this topic because it hits close to home for me and I want to continue preserving these soldiers\u27 stories for generations to come.https://digitalcommons.jsu.edu/ce_jsustudentsymp_2025/1003/thumbnail.jp
Targeting RNA Polymerase I in Ewing Sarcoma Therapy
Please note: no video is available for this presentation.
Ewing sarcoma is a rare and aggressive pediatric bone cancer with poor survival rates in patients, as low as in 30% in advanced or recurrent cases. There are limited treatment options, making molecularly-targeted therapy vital to explore. Through CRISPR scans of Ewing sarcoma cell lines, ribosome biogenesis was highlighted as a potential target. As RNA polymerase I is a key component of ribosome biogenesis, the cytotoxic ability of two RNA Polymerase I inhibitors, CX-5461 and BMH-21, were used on Ewing sarcoma cells. The efficacy of the drugs on two cell lines were determined via measuring cell viability, migration potential, and colony formation potential after drug treatments. RNA levels were measured after drug treatment to determine the level of inhibition of RNA polymerase I. The growth of multicellular spheroids that resemble tumors were treated and grown over time to show the growth of the cancer cells, as well as the cytotoxicity of the RNA Polymerase I inhibitors. This presentation details the results and efficacy of the two potential targeted therapies on Ewing sarcoma cell lines.https://digitalcommons.jsu.edu/ce_jsustudentsymp_2025/1001/thumbnail.jp
