Summary

The relationship between 18 species of native unionid bivalves and the exotic zebra mussel, Dreissena polymorpha, was explored at a monitoring site in Pool 26 of the Mississippi River. From 1992 to 1993, colonization rates increased from 27% to 99.7% of unionids, and the mean number of D. polymorpha per unionid increased from 2.2 to 37.4. The number of D. polymorpha per unionid shell was related to shell length and varied among species. Four types of colonization patterns were found, each differing from the others in the relative number of colonizing D. polymorpha. Shell and ornamentation types were differentially colonized. Thick-shelled, ornamented species were more heavily colonized than were thin-shelled, unornamented species. [...]
