Revisiting the advertisement call features of Scinax montivagus (Anura: Hylidae)

Abstract

In the present study, we revisit the advertisement call of Scinax montivagus based on new recordings from Rio de Contas, state of Bahia, Brazil. The species' call consists of a single type of multipulsed note of relatively short duration (mean = 192 ms), having two non-harmonically related emphasized frequency bands. The dominant frequency corresponds either to the lower or the higher band, or it may shift between both along call emissions. Herein, we assess and discuss call features that diverge from what is in the literature and also provide further details on the species call. We reinforce that detailed and standardized advertisement call descriptions of different Scinax species would contribute to acoustic diagnosis between them.

Reassessment of the advertisement call of topotypic Scinax squalirostris (Anura: Hylidae), with an acoustic evaluation of its occurrence in the Serra da Mantiqueira, southeastern Brazil

“…Thus, calls in the initial portion of a call series (weak/low amplitude) had their dominant frequencies concentrated in the lower band, whereas calls of middle and last portions of the series (higher and stable amplitude) had more energy in the upper frequency band. Similar between-bands shifts in dominant frequency is known for calls of other species of Scinax (e.g., Magrini et al 2011, Carvalho et al 2015, Novaes and Zina 2016, Lopes et al 2019. Also, the mean value of notes per call reported by Garey et al (2018) should be read 10, not 1 (M. V. Garey, pers.…”

“…The recent study by Lopes et al (2020) reported some differences in calls from specimens from different populations originally assigned to Scinax garbei. They inferred that these belong to three different lineages, which seem to correspond to our Scinax sp.…”
