This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant award of $118,674 to Florida State University (FSU) will assess the impact of extreme flooding from Hurricane Helene on the population genetic structure and phenotypic traits of several freshwater fish species in the Southern Appalachian region. The project aims to resample approximately 20 previously studied sites across the upper Tennessee, Savannah, and Santee River basins to evaluate changes in the genetic diversity and physical characteristics of targeted fish populations before and after the hurricane. By leveraging pre-storm genomic data and morphological measurements, the research will investigate how extreme flooding and associated habitat disruption influence evolutionary processes in these freshwater ecosystems. The award period runs from December 1, 2024 to November 30, 2025. No sub-awards are planned under this grant.
