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.
