Data from: Receiver discriminability drives the evolution of complex sexual signals by sexual selection

Flat stimulusFlat calls (F) in which the frequency among notes did not vary. This data if for Fig.1Natural stimulusNatural calls (N) in which the fundamental frequency (F0) increases in the species-typical manner (i.e. naturally) from note to note: 441 Hz, 551 Hz, 589 Hz, 606 Hz, 618 Hz, 628 Hz, 628 Hz and 628 Hz, respectively.This data if for Fig.1Extra increase stimulusExaggerated frequency increase calls (E) in which the increase in frequency among notes was exaggerated artificially using Avisoft SAS-Lab Pro.This data if for Fig.1Phonotaxis data of the three group with different frequency increasePhonotaxis data of the three group with different frequency increase(before combine the data of ratio 0.6 and 0.625)Phonotaxis data of the three group with different frequency increase (after combine the ratios of 0.6 and 0.625)Phonotaxis data of the three group with different frequency increase (after combine the ratios of 0.6 and 0.625),this data is for Fig.2Phonotaxis data of the relative attractivenessPhonotaxis data of the relative attractiveness,this data is for Fig.3Phonotaxis data of the relative attractiveness(combined data)Phonotaxis data of the relative attractiveness,combined data of 4,5,6 note numbers to E-F,N-F,or E-N
