Figure 5.

Multiple PTVs are attracted to the same sites. (A) PTVs are more likely to pause when other PTVs are present (green). Spatially randomized simulations are shown in light green and cannot account for the tendency of PTVs to pause simultaneously with other PTVs. (B) STVs are not more likely to pause when other STVs are already present (magenta). Simulations are shown for comparison (light magenta). Error bars represent 95% confidence intervals; *95% confidence intervals do not overlap.
