CERC’s Toxicology Branch has a long history of working with federal, state, and tribal partners on research related to the effects of contaminants and other stressors on freshwater mussels, one of the most endangered species in North America. The unique laboratory facilities at CERC allow scientists to conduct laboratory and field studies across the life cycle of mussels providing federal, state, and tribal natural resource managers better information to protect endangered mussel species.
