Daftar Isi: Supplementary material S27: A comparison between the spectra of jolting and walking pulses on each substrate

Daftar Isi:

Comparison of the average jolting pulse spectra against the average walking pulse spectra, on each substrate. Each collection of pulses (walking or jolting on each substrate) was individually sorted by magnitude and the strongest ones in the collection averaged. The purpose of this is to demonstrate a possible discrimination between the two different behaviours on each substrate on the basis of the pulse spectral features. The number of pulses chosen to be averaged for each collection differs based upon the extent of the collection of spectra and their clarity/quality (petri-dish jolting n = 15, petri-dish walking n = 40, honeycomb jolting n = 10, honeycomb walking n = 40, brood-comb jolting n = 20, brood-comb walking n = 20). All averaged pulses were high pass filtered with a cut-off at 300 Hz to remove background noise without interfering with the frequencies where the signal of interest occurs.
