Figure 5. Rarefaction curves for the species richness of invertebrates of a grassland soil assemblage at three dates (winter experiment): A = pre-treatment; B = 20 days after treatment and C = 40 days after treatment. Continuous lines above and below Beauveria bassiana and lambda-cyhalothrin curves are 95% confidence limits calculated over 1000 iterations (Gotelli and Colwell, 2001).
