Segmented regression of movement rate. The loge frequency distribution of movement rates for all dispersers combined, during their dispersal period. Movement rates were binned and the loge frequency in each bin was plotted, sensu Johnson et al. 2002 . A segmented linear regression model was fit (red lines, r2 = 0.93) for which a breakpoint of 7.118 m min-1 was identified using the R package segmented. A null model linear regression model is also shown for comparison (black, dashed line, r2 = 0.82).
