Figure 2. Histogram of observed and simulated values of Wardle's (1995) index V. Observed V's were calculated for 53 morphospecies that were represented by 20 or more individuals in our total sample. Simulated V's were generated randomly from 10 simulations as described in the text. V = 0 for morphospecies with equal numbers of individuals collected from reduced wax and normal pea plots. Positive values of V indicate that more individuals were collected from normal wax peas, while negative values indicate that more individuals were collected from reduced wax peas. Greater absolute values indicate a greater disparity in collections from the two types of peas.
