Median Box plots showing the distribution of MMI values among wetland classes and statistically significant differences within classes between Phase I and II. Box area represents inner quartile range, while “whiskers” represent the upper and lower observations. MMI Result Conclusions Tests of MMI‟s response to measures of floodplain connectivity including the DTF, distance from the Missouri River Channel, and measured distance between the sample wetlands did not reveal any significant relationships between the MMI and measures of connectivity. The MMI‟s significant correlation to the mean conductivity mS/cm measure was the only indirect evidence that hydrological connectivity might be affecting wetland macroinvertebrate community structure, given that mean conductivity also had significant relationships to the DTF and distance from the Missouri River channel measure. Despite this the MMI did show consistent congruency with the other wetland assessment indices and water chemistry metrics, providing evidence that the Phase I reference sample population overall had greater wetland quality. The strongest feature of this MMI is that does not significantly respond to potential ecoregion, class, or type differences, yet it can discriminate reference candidates from the random population regardless of the spatial location of the wetland or classification. The combination of highly responsive individual macroinvertebrate metrics to multiple stressors contributes to a robust measure of biological integrity across a variety of wetland types and classes within this study population. 100 90 80 70 60 50 40 30 20 10 0 74 of 84 b 1 2 Wetland Class
