Notes on the Courtship Behavior of Aplastodiscus Arildae (Cruz & Peixoto, 1985) at an Urban Forest Fragment in Southeastern Brazil (Amphibia, Anura, Hylidae)
The courtship behavior, advertisement call, and courtship call of Aplastodiscus arildae are described based on observations realized at Parque das Mangabeiras, Belo Horizonte, Minas Gerais, Southeastern Brazil. Calling males were observed at leaves above the stream or on the litter near rivulet banks approximately all year. Female is attracted by the calling male and conducted to the subterranean nest, a different place from the calling site. The courtship event involves alternated mutual touches by the couple and calls with higher repetition rate emitted by the male. Aplastodiscus arildae presents reproductive mode with aquatic eggs deposited in subterranean nests. The advertisement call and courtship call consisted of a sequence of a unique no pulsed note, but the first presents larger interval among the calls and duration and higher dominant frequency than the last.
