Conclusion

This work investigated aspects of the environmental condition, social context and morphological factors on the acoustic parameters of the Yellow Heart-tongued Frog (Phyllodytes luteolus ) advertisement call when exposed to anthropic road noise. The results show that the dominant frequency of calls is higher in environments without traffic noise. In addition, we also found that larger males can produce signals with greater intensity. As the emission of calls is the main form of communication in anurans, we concluded that P. luteolus presented characteristics in the structure of the advertisement call that may represent advantages in noisy anthropic environments. Future studies are important to investigate how different sources of noise can affect in different ways the acoustic communication and population dynamics of organisms that use the emission of acoustic signals to communicate.
