Abstract: The present study evaluates variations in frequency and duration
parameters of whistles of four dolphin species (Sotalia guianensis,
Steno bredanensis, Stenella frontalis, and Tursiops truncatus), recorded
in the Rio de Janeiro State Coast, Southeastern Brazil. A total of 487
whistles were analyzed. Acoustic parameters of the whistles were classified
to species by discriminant function analysis. Overall classification
score was 72.5%, with the highest classification score obtained for
whistles of S. bredanensis and the lowest obtained for S. frontalis. Most
differences were among S. bredanensis and S. guianensis, species that
did not have their repertoires compared in other studies.

The publication is available online (
or by request (isabelaseabra.lima at gmail.com)
