Selective pressure imposed by predators promoted the emergence of distinguishable defensive behaviors that may be adaptive for the part or the entire population. This process is the group selection, since natural selection is elevated to the collective of individuals. Frogs exhibit about 30 defensive strategies, and the one of themost conspicuous is the emission of distress calls, a loud and with high vocalization,which potentially may frighten predators. Such behavior may also warn conspescific neighbors about the predator presence. In this context, it is expected that the distress call has an adaptive value for group selection, since this behavior may increase survivorship of neighbors as well. Thus, we hypothesized that conspecifics individuals will show behavioral responses to distress call playbacks. By recognizing the distress call is possible that there are postural changes, they may stop the calling activity, or they could flee away or hide. We aim to test this hypothesis and to assess the effect, if any, by means of playback experiments in the field, under natural conditions. Theferore, we selected Hypsiboas bischoffi and H. faber (Hylinae) as models for the study based on previous naturalistic observations. The selected sites are in the Atlantic rainforest in the state of São Paulo. (AU)
