Call differences and calling site segregation in anuran species from central Amazonian floating meadows

Abstract: The acoustic behaviour of 15 sympatric and synchronically breeding species of frogs in an area of floating meadows near Manaus (Brazil) was studied for a period of 8 months. The calling positions of each species can be identified with certain physiognomic types of vegetation.Sound analyses were used to compare the mating calls. The main variables are dominant frequency, call duration and pulse repetition rate. Each of the 15 species has a distinct mating call and differs from the acoustic behaviour of each oth… Show more

“…all of 23 open habitat species in the Manaus area (Hodl, 1977;Zimmerman, 1982). Undoubtedly, the primary function of vocalization by anurans is for species recog nition so that females are able to track conspecific males (Greer & Wells, 1981 and many previous studies).…”

“…Calls of some Amazonian frogs species were analyzed spectrographica 11 γ by Duellman (1970; (mainly hy1 ids); Schluter (1979; )980) (hylids and microhy1 ids); Heyer (1978; and Straughan & Heyer (1976) (leptodactylids). Hodl (1977) analysed the calls of 17 species of Central Amazonian floating meadow frogs (mostly hylids). Hod 1's study was the only one to characterize the acoustics of a single Central Amazonian anuran community and presented detailed analyses of each species call measured from more than only one or two individua 1 5 .…”

“…Esta especificidade de sítio de vocalização tem sido registrada em outros estudos com comunidades de anuros (e.g. Hödl 1977, Rossa-Feres & Jim 2001e Bertoluci & Rodrigues 2002) e parece ser uma extensão filogenética adicional ao comportamento de isolamento acústico em muitas espécies (Etges 1987), que otimiza o uso de hábitats reprodutivos pela assembléia de anuros (Bertoluci & Rodrigues 2002).…”

“…O canto de anúncio é a vocalização mais freqüentemente emitida pelos machos (Wells 1977), pois contém informações espectrais e/ou temporais importantes para o reconhecimento específico (Gerhardt 1983, Ryan 1985, Cocroft & Ryan 1995, e apresenta adaptações que evitam ou minimizam a interferência acústica na comunicação (Grafe 1996, Martins & Jim 2003, Martins et al 2006, permitindo a coexistência de várias espécies no mesmo ambiente (Duellman & Pyles 1983, Cardoso & Viellard 1990, Márquez et al 1993, Bastos & Haddad 1995, Viellard & Cardoso 1996, Martins & Jim 2003e Martins et al 2006). Do ponto de vista da comunidade, a análise da vocalização indica que as espécies simpátricas vocalizam com diferenças significantes e com pequena sobreposição nos parâmetros acústicos (Duellman 1967, Hödl 1977, Cardoso & Viellard 1990, embora este padrão nem sempre seja encontrado (Chek et al 2003).…”

“…A segregação que ocorre entre as espécies de anuros durante a atividade reprodutiva está relacionada com as características físicas do hábitat (RABB 1973, CARDOSO et al 1989, com a morfologia e com o tamanho de cada espécie (CRUMP 1971, HÖDL 1977, ROSSA-FERES & JIM 2001, BERTOLUCI & RODRIGUES 2002.…”
