Summary of pairwise comparisons of FID (logged) for analyses of each species across stimulus types (i.e. where ≥5 replicates were obtained for any stimulus type).

Brackets after the species name refer to the number of significant comparisons (out of the comparisons conducted). Square brackets refer to the observed power of the analysis. Single walker (SW), multiple walkers (MW), bicycle (CYC), car (CAR) and bus (BUS).
Blanks indicate no comparison was possible, ‘NS’ is not significant, ‘*’ means P<0.05, ‘**’ means P<0.01 and ‘***’ means P<0.001.
