摘要:In 2014, the University of Minnesota, Macalester College, and the Minnesota Department of Natural Resources began work on a multi-year study of mussel health in selected Minnesota rivers. The research, funded by the Legislative-Citizens Commission on Minnesota Resources, combined experimental study with field investigation to explore relationships between specific indicators of water quality and biological measures of the health of particular organisms. Mussels are bottom-dwelling filter feeders, and are therefore important “indicator species” of stream water quality. The work described in this article was a significant component of the broader, three year project.
