20.500.12556/RUL-155361 Leafhopper males compensate for unclear directional cues in vibration-mediated mate localization Ambient noise and transmission properties of the substrate pose challenges in vibrational signal-mediated mating behavior of arthropods, because vibrational signal production is energetically demanding. We explored implications of these challenges in the leafhopper Aphrodes makarovi (Insecta: Hemiptera: Cicadellidae) by exposing males to various kinds of vibrational noise on a natural substrate and challenging them to find the source of the female playback. Contrary to expectations, males exposed to noise were at least as efficient as control males on account of similar searching success with less signaling effort, while playing back male–female duets allowed the males to switch to satellite behavior and locate the target without signaling, as expected. We found altered mitochondrial structure in males with high signaling effort that likely indicate early damaging processes at the cellular level in tymbal muscle, but no relation between biochemical markers of oxidative stress and signaling effort. Analysis of signal transmission revealed ambiguous amplitude gradients, which might explain relatively low searching success, but it also indicates the existence of behavioral adaptations to complex vibrational environments. We conclude that the observed searching tactic, emphasizing speed rather than thorough evaluation of directional cues, may compensate for unclear stimuli when the target is near. biotremology vibrational communication sexual behavior of insects impact of noise on behavior metabolism of vibrational production animal behaviour entomology biotremologija vibracijska komunikacija spolno vedenje žuželk vpliv šuma na vedenje metabolizem produkcije vibracij entomologija true false true Angleški jezik Slovenski jezik Članek v reviji 2024-03-27 15:41:21 2024-03-27 15:41:26 2024-03-28 03:55:25 0000-00-00 00:00:00 2023 0 0 13 str. art. 8879 Vol. 13 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 59 2045-2322 10.1038/s41598-023-35057-z 154300163 s41598-023-35057-z.pdf s41598-023-35057-z.pdf 1 B97C6C6CFC93A0A3F713AA0F06651718 3004ce7a7976e7c92724f350dd17730076ef459d5a855c2ea64a20db2e917018 6816f82d-ec48-11ee-aa14-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182212 https://www.nature.com/articles/s41598-023-35057-z 0 475fa3b3-ec48-11ee-aa14-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182211 Biotehniška fakulteta 0 0 0
