8. Box-and-whisker plots of environmental variables collected at sites where
E. complanata was present (P) or absent (A). Conditions at sites with and
without E. complanata were compared using the Kolmogorov-Smirnov
(water chemistry, habitat, and land use variables) or Mann-Whitney U test
(habitat metrics and biological indexes)……………………..……………….20-24
9. Locations where Elliptio fisheriana (northern lance) was collected…………….25
10. Box-and-whisker plots of environmental variables collected at sites where
E. fisheriana was present (P) or absent (A). Conditions at sites with and
