Ryan S. King, Matthew E. Baker, Dennis F. Whigham, Donald E. Weller, Thomas E. Jordan, Paul F. Kazyak, and Martin K. Hurd. 2005. Spatial considerations for linking watershed land cover to ecological indicators in streams. Ecological Applications 15:137–153.

Appendix B. Scientific names, nonmetric multidimensional scaling (nMDS) Axis 1 scores, frequencies of occurrence, and tolerance values for all macroinveretebrate taxa with at least 10 occurrences in the MBSS data set (N = 295 stream sites sampled). Taxa are listed in rank order of nMDS scores. High scores correspond to watersheds with low percentage developed land.

Taxa scores represent the weighted centroid along nMDS Axis 1.

EPT = Ephemeroptera, Plecoptera, Trichoptera.  EPT taxa are generally considered sensitive to pollution (Barbour et al. 1999).

§TolVal = Tolerance value.  TolVals range from 0 to 10, where 0 = intolerant of pollution.  TolVals correspond to regional scores provided in Barbour et al (1999).  Family-level TolVals were substituted for genera lacking genus-level values.
