| Popis: | Female crickets (Gryllidae) often rely on the quality of male acoustic signals when choosing a potential mate. This quality can be determined by the frequency and temporal structure of the calling song, and both these characteristics are known to change as males grow old. In addition, female choice is influenced by call amplitude, which is primarily a function of the distance between a singing male and the recipient female. In this study, we use a binary choice experimental design to test whether an old male, whose song appeared to be less attractive in terms of its frequency and temporal structure, may benefit from its increased amplitude. We demonstrate that increased amplitude does improve attractiveness of the calling song chirped by an older male. We also show that female preference for young males does not change with female age. These findings are discussed in light of possible behavioral strategies and spatial distribution of young and old males in the field. |
