To expand the scope of soundscape ecology to encompass substrate-borne vibrations (i.e. vibroscapes), we analyzed vibroscape a deciduous forest floor using contact microphone arrays followed by automated processing large audio datasets. We then focused on vibratory signaling ground-dwelling Schizocosa wolf spiders test for (i) acoustic niche partitioning and (ii) plastic behavioral responses that might reduce risk signal interference from noise conspecific/heterospecific signaling. Two closely related species - S. stridulans uetzi showed high overlap across space, time, dominant frequency. Both show males shorten their courtship in higher abundance noise, increased duration signals conspecific signals, decreased complexity signals.
