Acoustic signaling is the most widespread and studied mode of communication for transmission of intraspecific information in anurans. However, alternative communication modes, such as chemical, seismic, tactile, and visual, also contribute to the behavioral repertoire of anurans. Transmission of information can occur through one of these modes (unimodal) or involve the combination of two or more (multimodal communication). In addition, the use of an anatomical structure (e.g., vocal sacs), body color, or posture of the sender can transmit information to receivers. These secondary cues could provide redundant information, reinforcing some characteristic, or bring something complementary or fundamental to the interaction between individuals. Recently, researchers have demonstrated, through field observations and experiments containing choice trials, that a range of signals, aside from acoustic signals alone, play an important role in the process of mate-choice. In addition, besides the environmental and intrinsic effects on the individual, the anurans behavior can be influenced by its pathogens. Currently, Batrachochytrium dendrobatidis is considered one of the major responsible for the decline of amphibian populations, but little is known about the sublethal effect of this fungus on anurans communication. For this, we will investigate the multimodal communication in three species of Neotropical anurans, Agalychnis callidryas, Boana albomarginata and Hylodes phyllodes, with a special focus on the body color function as visual cue and indicative of physical characteristics, together with the other communication modes in the intraspecific relations; in addition to investigating the influence of abiotic noise and Bd infection in the different communication modes, contributing to the understanding of variation in animal communication.
