20.500.12556/DiRROS-20858 Vibrational noise disrupts Nezara viridula communication, irrespective of spectral overlap Insects rely on substrate vibrations in numerous intra- and interspecific interactions. Yet, our knowledge of noise impact in this modality lags behind that in audition, limiting our understanding of how anthropogenic noise affects insect communities. Auditory research has linked impaired signal perception in noise (i.e., masking) to spectral overlap. We investigated the impact of noise with different spectral compositions on the vibrational communication of the stink bug Nezara viridula, examining courtship behaviour and signal representation by sensory neurons. We found negative effects of vibrational noise regardless of spectral overlap, challenging common expectations. Noise impaired the ability of males to recognize the female signal and localise its source: overlapping noise decreased sensitivity of receptor neurons to the signal and disrupted signal frequency encoding by phase-locking units, while non-overlapping noise only affected frequency encoding. Modelling neuronal spike triggering in sensory neurons linked disrupted frequency encoding to interference-induced alterations of the signal waveform. These alterations also affected time delays between signal arrivals to different legs, crucial for localisation. Our study thus unveils a new masking mechanism, potentially unique to insect vibrosensory systems. The findings highlight the higher vulnerability of vibration-mediated behaviour to noise, with implications for insect interactions in natural and anthropogenically altered environments. biotremology vibrations noise communication neurons masking entomology neurobiology biotremologija vibracijski šum stenice spolno vedenje entomologija nevrobiologija Nezara viridula true false true Angleški jezik Slovenski jezik Neznano 2024-11-21 20:40:15 2024-11-21 20:40:15 2025-01-10 08:47:21 0000-00-00 00:00:00 2024 0 0 Ostali avtorji: Nataša Stritih-Peljhan, Aleš Škorjanc, Jernej Polajnar & Meta Virant-Doberlet; Nasl. z nasl. zaslona; Opis vira z dne 21. 11. 2024; str. 1-12 [Vol.] 7 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2024-11-19 591 2399-3642 10.1038/s42003-024-07185-3 216019971 https://doi.org/10.1038/s42003-024-07185-3 1 70c4b2ce-a840-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29467 RAZ_Janza_Rok_2024.pdf RAZ_Janza_Rok_2024.pdf 1 BBFFDC6A1EE4C43C5528158341870DBC ae6f02740b0e1de309f4254da53bddd276317169681210caf7457f30e8159fdb af8bd0c2-a840-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29468 Nacionalni inštitut za biologijo Unconventional masking 0 0 0
