An asymmetrical representation of leader and follower signals in pairs of direction-selective neurons of the auditory pathway was suggested to represent the neural basis for the preference of females. We investigated the time\u2013intensity trading effect, which occurs when the temporal advantage of the leader signal is compensated, and can be reversed, by an additional sound pressure level of the follower. In behavioural arena trials the intensity trading of the preference of females for leader signals depends on the playback level; a higher sound pressure level (SPL) is needed for compensation at higher playback levels. We studied the simultaneous neuronal representation of leader and follower signals, and the time\u2013intensity trading function in the pair of omega-neurons in the CNS. Consistent with the behavioural data, the representation of leader and follower signals can be reversed with an additional loudness of the follower, and the steepness of the trading function depends on the playback level. We also implemented data on the neuronal representation of synchronized signals in individual receivers into computer-based agents, which performed phonotaxis in a virtual sound field. Results of these simulations closely resemble those obtained from real females with respect to the overall preference under the various time\u2013intensity trading conditions. Furthermore, in combination with the observed trading functions these simulations demonstrate, that under more realistic field conditions the ultimate success of followers in attracting females is much higher than suggested from arena trials. We discuss the evolutionary consequences for male calling strategies in synchronously calling Orthoptera.<\/jats:p>","DOI":"10.1242\/jeb.02655","type":"journal-article","created":{"date-parts":[[2007,1,18]],"date-time":"2007-01-18T01:32:04Z","timestamp":1169083924000},"page":"465-476","source":"Crossref","is-referenced-by-count":32,"title":["Neuroethology of female preference in the synchronously singing bushcricket <i>Mecopoda elongata<\/i> (Tettigoniidae; Orthoptera): why do followers call at all?"],"prefix":"10.1242","volume":"210","author":[{"given":"Ismene","family":"Fertschai","sequence":"first","affiliation":[{"name":"Institute of Zoology, Karl-Franzens-University, A 8010 Graz,Universita\u0308tsplatz 2, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ju\u0308rgen","family":"Stradner","sequence":"additional","affiliation":[{"name":"Institute of Zoology, Karl-Franzens-University, A 8010 Graz,Universita\u0308tsplatz 2, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heiner","family":"Ro\u0308mer","sequence":"additional","affiliation":[{"name":"Institute of Zoology, Karl-Franzens-University, A 8010 Graz,Universita\u0308tsplatz 2, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042500351341000_REF1","doi-asserted-by":"crossref","unstructured":"Arak, A. and Eiriksson, T.
