Appendix J. Nonmetrical multidimensional scaling (MDS) for (A) Site one and (B) Site two. Letters represent experimental treatments: T = total exclusion, H = Half-Wall Roof, W = Wall, R = Roof, and C = Control. Numbers represent the weeks when monitoring took place: (0) August 1997, (16) December 1997, (28) March 1998, (40) June 1998, (52) September 1998, (64) December 1998, (76) March 1999, (88) June 1999, and (100) September 1999. Circles identify MDS clusters based on Bray Curtis similarity analysis.
