A grave drum at rocky springs: the vocalization of Bokermannohyla alvarengai (Anura: Hylidae) from the Espinhaço Range, southeastern Brazil, with notes on its natural history
Abstract:Communication in anurans is mediated mainly by acoustic signals, which are relevant for mating, territoriality, and other social interactions (Wells 2007).
