Oscillogram and spectrogram of Neoaliturus grandidentis male calls

The male calls (vibrational signals transmitted through the plant) were recorded in Nahal Shitta, Israel, using the pickup cartridge method (Tishechkin 2022), with a EQ-7545R Preamplifier. Oscillograms and a spectrogram of the male call were prepared using the ‘spectro’ function implemented in the R package Seewave (Sueur et al. 2008). RX 9 Audio Editor v. 9.3.0.1435 was used to reduce background noise; its screen recording via Free Cam v. 8 was used to create the dynamic oscillogram and spectrogram. Terminology of vocal calls follows Bluemel et al. (2014) and Tishechkin (2021).
