Filtration by Corbicula fluminea resulted in significant reductions in suspended organic matter in a Savannah River tributary. The invading clam filtered at much higher rates than the native unionid mussel Elliptio complanata, but the presence of the clam had no effect on the mussel's growth rates (Leff et al. 1990). | ||
