Federal Grant Award Summary

The National Science Foundation (NSF) Division of Molecular and Cellular Biosciences awarded $394,798 to Louisiana State University Agricultural Center on January 1, 2027, under the Biological Sciences program (CFDA 47.074) for a collaborative research project examining freshwater mussel physiological responses to multiple environmental stressors. The project, which extends 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 regimes. This research directly addresses a critical conservation gap, as approximately 66% of North American freshwater mussel species face threats of extinction despite their essential roles as ecosystem engineers that filter water, recycle nutrients, and modify habitats.

The project will deliver evidence-based physiological data and risk assessment tools to inform mussel conservation and management strategies for state, federal, and international agencies. By combining traditional research techniques with machine learning and data analytics, the research will provide stage-specific and species-specific performance predictions under varying environmental conditions. Additionally, the project supports workforce development through STEM career encouragement for K-12 and college students across three EPSCoR (Established Program to Stimulate Competitive Research) states, and enhances public engagement via exhibits and video displays developed with local science centers, zoos, and museums. The DEB modeling approach may also yield broader applications for aquaculture and agriculture practices through improved performance predictions under changing environmental conditions.
