Do natural differences in acoustic signals really interfere in conspecific recognition in the pan-Amazonian frog Allobates femoralis ? Luciana K. Erdtmann 1) , Pedro I.

Postal 478, Aleixo, Manaus, AM 69060-001, Brazil) (Accepted: 28 February 2011) Summary The call of the pan-Amazonian frog Allobates femoralis shows wide geographical variation, and males show a stereotyped and conspicuous phonotactic response to playback of conspe- cific calls. We evaluated the capacity of males of A. femoralis and a closely related species A. hodli to respond aggressively to natural conspecific and heterospecific calls varying in number of notes, by means of field playback experiments performed at two sites in the Brazil- ian Amazon. The first site, Cachoeira do Jirau (Porto Velho, Rondônia), is a parapatric con- tact zone between A. femoralis that use 4-note calls, and A. hodli with 2-note calls, where we performed cross-playbacks in both focal populations. The second site, the Reserva Florestal Adolpho Ducke (Manaus, Amazonas), contained only A. femoralis with 4-note calls. There, we broadcast natural stimuli of 2-note A. hodli , 3-note
