Hylodes asper tem um sistema de comunicaГ§ГЈo visual complexo, destacando-se a sinalizaГ§ГЈo realizada com os membros posteriores ('foot-flagging'), que Г© a mais distintiva dentro do repertГіrio de sinais visuais. Estes sistemas de comunicaГ§ГЈo sГЈo usados durante interaГ§Гµes intraespecГficas envolvendo machos, fГЄmeas e subadultos. / Os comportamentos de sinalizaГ§ГЈo, territorial e de corte foram estudados para o anuro diurno Hylodes asper, com base nos sistemas de comunicaГ§ГЈo acГєstica e visual. asper excavate underwater chambers that are probably used to shelter the eggs and to prevent the clutch from being drifted downstream. The noise and the nearly constant and high humidity produced by the torrents and waterfalls, along with the availability of light, probably favored the evolution of contrasting colors and visual communication in H. Thus, the ambient noise produced by the water current may not interfere significantly with the acoustic communication of this species. asper are spectrally different from the noise produced by the water current. Although the ambient sound pressure levels (SPL), measured at the calling sites, are similar to the SPL of the advertisement calls, the high-pitched calls of H.

The splash zone produced by the waterfalls and torrents creates a high, nearly constant, humidity near the streams, reducing the risk of desiccation which enables the diurnal activity of H. Hylodes asper has a complex visual communication system, of which foot-flagging is the most distinctive display observed in the repertoire of visual signals. Visual and acoustic communication were used during intraspecific interactions involving males, females, and subadults.

We studied the signaling, territorial, and courtship behaviors of the diurnal frog Hylodes asper.
