Lima, I.M.S; Andrade, L.G; Bittencourt, L.; Bisi, T.L.; Flach, L.; Lailson-Brito Jr., J.; Azevedo, A.F. 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 ( http://scitation.aip.org/content/asa/journal/jasa/139/5/10.1121/1.4947310) or by request ([email protected]) Best regards, Isabela Lima -- Isabela Maria Seabra de Lima Bióloga - Doutoranda no Programa de Pós-graduação em Ecologia e Evolução/UERJ Laboratório de Mamíferos Aquáticos e Bioindicadores - MAQUA Universidade do Estado do Rio de Janeiro - UERJ Rua São Francisco Xavier, 524 4º andar sala 4002 bloco E Maracanã, Rio de Janeiro - RJ CEP 20.550-013 Tel: 21 23340065
