Connecting morphological, behavioral, and genetic variation in Erimystax chubs
Wynn Haslam, Biology & Fish Conservation
Working with Dr. Paul Angermeier & Dr. Emmanuel Frimpong
Wynn seeks to better understand the differences between Erimystax chubs found in the Clinch and Powell Rivers. The aim of this research is to answer whether the morphological variation is related to genetic variation, if there is interspecific hybridization and if reproductive behaviors differ. Data will be assessed, and DNA will be analyzed. The outcome will be a written report and more information on species preservation will be generated.
The effects of urbanization on neural organization in wild song sparrows
Sakshi Kaul, Neuroscience
Working with Dr. Kendra Sewall
To better understand the effects of urbanization on wildlife, Sakshi will compare the Arginine vasotocin neuropeptide during development in the brain of urban and rural Melospiza melodia (song sparrows) using immunohistochemistry. This study is a means of determining the significance of animal interaction with our built environment.
Impacts of siltation on community composition and spatial distribution of stream fish ecological guilds in Tom’s Creek
Nathaniel Lambert, Fish Conservation
Working with Dr. Holly Kindsvater
Nathaniel will use the previously developed 11 sampling locations along Tom’s Creek to electrify fish and assess thalweg depth, flow, substrate composition and fish community composition; specific comparison will be made between benthic species and silt levels. Findings can be used to create impact models.
Investigating the dissemination of antimicrobial resistance genes in Salmonella Typhimurium through horizontal gene transfer
Leela Ohri, Biochemistry; National Security & Foreign Affairs
Working with Dr. Jingqiu Liao
Leela will profile antimicrobial resistance genes in Salmonella using a BLAST analysis against the Comprehensive Antibiotic Resistance Database based on Whole-Genome Sequencing data. She will then perform a population genetics analysis in combination with statistical tests to identify evidence of horizontal gene transfer and quantify its frequency. The purpose of this study is to advance the knowledge of the diversity of antimicrobial resistance genes in Salmonella in different hosts and environments and enhance our ability to tailor future treatments for maximum effectiveness.
The effectiveness of at-home water filters at removing PFAS and camping straws at removing microplastics
