Figure 2.

Comparisons of average number, length, and dry weight of invertebrates captured. For sample sizes, see Table 1. With 1-week pitfall traps and searches, only invertebrates ≥ 5 mm were taken into consideration. The asterisks indicate a significant difference (P < 0.001). (A) Average number of invertebrates captured/sample. (B) Average length of invertebrates captured (mm). (C) Average dry weight of invertebrates/sample (mg). For sticky traps and 1-day pitfall traps, dry weight was estimated by using the appropriate regression equations (19).
