Federal Project Grant Award Summary

The National Science Foundation (NSF), Division of Molecular and Cellular Biosciences, awarded $658,292 to the University of South Dakota on January 1, 2027, through the Biological Sciences program (CFDA 47.074) to conduct collaborative research examining freshwater mussel physiological responses to multiple environmental stressors. The project, spanning through December 31, 2030, integrates subcellular biomarkers, physiological experiments, field studies, and Dynamic Energy Budget (DEB) modeling to assess how two freshwater mussel species respond to changes in water temperature and sedimentation. The research addresses a critical conservation gap, as approximately 66% of North American freshwater mussel species are threatened, endangered, or extinct due to environmental alterations from agricultural runoff and water-use projects such as dam construction.

The project delivers stage-specific and species-specific physiological data designed to inform conservation and management strategies for state, federal, and international agencies conducting mussel monitoring programs. Through the integration of machine learning and data analytics with traditional research techniques, the award advances understanding of mussel responses at the subcellular, individual, and population levels. Additionally, the project provides broader societal benefits by encouraging careers in science, technology, engineering, and mathematics (STEM) fields across three Experimental Program to Stimulate Competitive Research (EPSCoR) states and increasing public engagement through exhibits and educational displays developed with local science centers, zoos, and museums.
