“…Although the directionality of visual signals is unknown in nocturnal species of hylids, these species commonly have relatively rich repertoires of visual signals (as shown here for B. albopunctata), suggesting some level of importance for these stereotyped movements during intraspecific communication (Hartmann et al 2005, Toledo et al 2007, Gomez et al 2009. Moreover, visual signals in nocturnal hylids seem to function in attracting females, as reported for Aplastodiscus eugenioi (Carvalho-e-Silva and Carvalho-e-Silva, 2005) (Hartmann et al 2004), Boana curupi (Garcia, Faivovich, and Haddad, 2007) (Lipinski et al 2012), and Scinax cardosoi (Carvalho-e-Silva and Peixoto, 1991; = Ololygon cardosoi) (Moroti et al 2017). In addition, movements that produce visual signals also produce seismic signals (Narins 1990), especially when on high perches, with less stable substrates, such as breeding sites.…”

Multimodal signaling in Boana albopunctata (Anura: Hylidae): reading visual and acoustic cues. The acoustic mode of communication is important for anurans, but visual communication is beginning to be considered essential for some species, genera, and families. This study focuses on visual and acoustic signals in Boana albopunctata (Hylidae: Cophomantinae) in an attempt to increase our understanding of signaling in this nocturnal Neotropical treefrog. Visual signals were assessed to determine whether they are directed toward conspecific opponents, as has already been observed for some diurnal anurans, or associated with potential morphological asymmetries. Associations between visual and acoustic signals were explored. The results suggest that males may combine visual and acoustic signals (multimodal signaling) synergistically, thereby strengthening the efficiency of information transmission. Thus, in nocturnal anuran species, visual signals may function primarily as an alerting component and multimodal signaling may be a relevant way of communication.
