Abstract
Communication in anurans is mediated mainly by acoustic signals, which are relevant for mating, territoriality, and other social interactions (Wells 2007). Although these signals are usually conspicuous and relatively stereotyped, some Neotropical frogs display noticeable diversity and complexity in their calls. For instance, Bokermannohyla, a genus of gladiator treefrog from the Atlantic Forest, Cerrado, and Caatinga Biomes of Brazil, often have complex vocal repertoires (Carvalho et al. 2012; Nali & Prado 2014), whilst some congeners have simple and stereotyped calls emitted continuously (Carvalho et al. 2013; Taucce et al. 2015; Giaretta et al. 2016; Rocha et al. 2016).
