CHAMPAIGN, Ill. – Man-made levees and water pollution have made an impact on the fish and other fauna of the Illinois River throughout the 20th century, but researchers at the Prairie Research Institute (PRI), University of Illinois, have taken an even longer view of human-induced changes in freshwater mussels, dating back to pre-Columbian times.
Significant size changes in mussel shells suggest that the river environment has been altered. Read the full story from the Prairie Research Institute.
This PRI-funded study was recently published in the Journal of Science of the Total Environment.
