Abundance, species richness and diversity (H[prime]) of 1992 pitfall samples did not respond significantly to burning frequency (GLM t = 0.47, 1 d.f., P = 0.72; GLM t = 0.45, 1 d.f., P = 0.73; GLM t = 0.10, 1 d.f., P = 0.94) or burning in 1992 (GLM t = 0.04, 1 d.f., P = 0.97; GLM t = 0.33, 1 d.f., P = 0.80; GLM t = 0.22, 1 d.f., P = 0.86).
Abundance, species richness [ILLUSTRATION FOR FIGURE 2A, B OMITTED] and diversity (H[prime]) of 1994 light trap samples did not respond significantly to time of sampling, burning frequency (GLM t = 1.46, 8 d.f., P = 0.38; GLM t = 1.62, 8 d.f., P = 0.35; GLM t = 1.84, 8 d.f., P = 0.32) or burning in 1994 (GLM t = 1.48, 8 d.f., P = 0.18; GLM t = 1.64, 8 d.f., P = 0.14; GLM t = 1.49, 8 d.f., P = 0.17).
The number of Lepidoptera counted in visual transects in 1994 declined significantly with burning in 1994 (GLM t = 2.77, 8 d.f., P [less than] 0.05) and declined nonsignificantly with burning frequency [ILLUSTRATION FOR FIGURE 3 OMITTED].
