Appendix A. Scatterplots of community metrics in response to low levels of urban intensity (MA-NUII) among six U.S. metropolitan areas studied by Cuffney et al. (2010). EPTr = Richness of Ephemeroptera, Plecoptera, and Trichoptera; MDS1 = nonmetric multidimensional scaling scores along axis 1; RichTol = richness-weighted community tolerance value. RTH = Richest Targeted Habitat, quantitative sampling; QQ = all taxa collected per site based on combination of RTH and QMH (Qualitative Multi-Habitat) sampling (presence-absence data).
