Abstract
Daphnia lumholtzi, an exotic zooplankter, recently has become establis hed in the Illinois River. This species was first detected at Illinois River Mile (IRM)121.1 near Havana, Illinois in June of 1995, and exhi bited a peak abundance of 22.5/L in August. Population trends and dens ities in the Illinois River resemble those reported in lakes and reser voirs of the southeastern United States, suggesting D. lumholtzi is ad aptable to lotic as well as lentic systems. Individuals were found at sampling sites as far upriver as IRM 195.9.
