FIGURE SET

Figure 1

Figure 1. The effect of ant-following birds on the foraging success of the army ant Eciton burchellii in Panama. Shown are the standardized number of ant aggregations observed in each area of 18 paired trials (open boxes) and the difference between paired exclusion and control areas (shaded box). In the box plots, the horizontal line is the median (middle observation), the boxes show the interquartile range (25% of data points above and below the median), and the vertical bars show the range. The differences (shaded box) were significantly greater than zero (dashed horizontal line). From Wrege et al. (2005)
