Bioacústica e sítio de vocalização em taxocenoses de anuros de área aberta no noroeste paulista

Abstract: Abstract:The calling site and the acoustic parameters of the advertisement call were determined for 18 anuran species in six ponds in the northwest region of São Paulo State. The dominant frequency of the advertisement call was positively correlated with the CRC of the species: small size species vocalized in a higher frequency, whereas larger species vocalized in a lower frequency. The similarity in the spectral and temporal parameters of the advertisement call was high among 94% of the recorded species. The … Show more

“…This SU differed from the others by not showing plant stratification, being essentially characterized as a temporary pond in sandy soil the surroundings of which were covered by grasses ( Figure 2C). The dominant anuran species at P4 was the leptodactylid Pseudopaludicola mystacalis, a small-sized terrestrial and semiaquatic species that is abundant in wetlands of opens formations (Silva et al 2008, Ribeiro-Junior & Bertoluci 2009, Valdujo et al 2011. In shrubby vegetation zones the dominant species was a Terrarana, the craugastorid Pristimantis paulodutrai, the most abundant species in forested areas of the NC (Bastazini et al 2007).…”

“…The main environmental conflicts in the APA of NC are, currently, the disorderly land use, lack of basic sanitation, substitution of natural areas by Pinus and Eucalyptus plantations, indiscriminate intensification of cattle raising, overfishing, degradation of mangroves and predatory tourism in coastal districts (INEMA 2015). The municipalities of Esplanada, Conde and Jandaíra were considered by Silva et al (2008) as those with the most conserved areas in the NC due to their smaller degrees of urbanization.…”

“…Por outro lado, o uso do micro-habitat de vocalização também pode ser influenciado pela riqueza e composição de espécies nas taxocenoses (SILVA et al, 2008). Taxocenoses com elevada riqueza devem apresentar maior sobreposição decorrente do elevado nível de saturação espacial.…”

“…Muitos estudos tem evidenciado diferenciação no uso do micro-habitat entre diferentes linhagens de anuros SAZIMA, 2000;PRADO;POMBAL, 2005). Hilídeos e fllomedusas, animais que podem utilizar substratos verticais, frequentemente apresentam comportamento generalista no uso do substrato de canto, enquanto as demais linhagens estão mais restritas ao uso do solo ou água ROSSA-FERES, 2007;SILVA et al, 2008). Para Cardoso et al (1989) esta diferenciação está associada a presença de discos adesivos nos hilídeos, os quais possibilitam a exploração de novos substratos, com consequente redução da competição.…”
