Data are from a comeptition experiment in which shading by the dominant species was reduced in half the plots to test experimentally for effects on surrounding species. "Parameters measured were: shading/light avail in each plot and mass, percent cover, diversity, and species richness of surrounding species" Plot Distance Treatment Shade (%) Light (%) Dry Plant (g) % Cover Simpson Div Spp Richness 1 10 S 92.7 7.3 0.00 0 0.00 0 1 20 S 59.9 40.1 7.24 50 2.93 6 1 30 S 75.7 24.3 4.62 60 1.38 2 1 40 S 30.0 70.0 24.15 100 2.25 3 2 10 U 2.6 97.4 4.04 56 2.78 7 2 20 U 5.3 94.7 0.19 57 3.73 7 2 30 U 1.5 98.5 2.72 112 2.68 6 2 40 U 4.2 95.8 1.37 79 4.10 8 3 10 S 66.6 33.4 0.33 35 3.96 7 3 20 S 27.2 72.8 1.43 77 4.83 8 3 30 S 13.0 87.0 3.24 77 3.33 5 3 40 S 21.7 78.3 1.03 52 5.98 8 4 10 U 1.3 98.7 0.55 42 4.67 7 4 20 U 14.3 85.7 8.49 138 4.46 6 4 30 U 0.0 100.0 2.63 76 4.53 7 4 40 U 16.3 83.8 5.36 92 2.27 5 5 10 U 15.9 84.1 6.81 124 3.82 6 5 20 U 9.8 90.2 1.35 52 3.81 6 5 30 U 12.4 87.6 3.41 55 3.32 7 5 40 U 18.4 81.6 20.52 98 5.47 9 6 10 U 30.9 69.1 1.48 51 3.08 6 6 20 U 6.1 93.9 2.89 72 3.27 9 6 30 U 10.1 89.9 1.44 38 3.80 6 6 40 U 9.5 90.5 5.41 64 2.34 7 7 10 S 91.7 8.3 0.00 5 2.78 3 7 20 S 95.1 4.9 3.89 56 1.87 5 7 30 S 28.2 71.8 1.59 49 1.48 5 7 40 S 91.1 8.9 1.40 90 4.10 9 8 10 S 70.2 29.8 0.00 4 2.67 3 8 20 S 88.2 11.8 0.19 32 4.06 6 8 30 S 26.2 73.8 0.22 18 2.05 3 8 40 S 17.1 82.9 0.97 30 3.19 7
