Vocal Repertoire of Captive Capybara (Hydrochoerus hydrochaeris): Structure, Context and Function

摘要: In this work we describe the structure, behavioral context and functionality of vocal repertoire capybaras, a social Caviomorph rodent. Additionally, since territoriality is present in species, hypothesize occurrence differences among groups. We analyzed total 2069 calls emitted by 28 animals from three different The capybara’s comprised seven call types (whistle, cry, whine, squeal, bark, click tooth-chattering). vocalizations were functionally categorized as contact, alarm, distress agonistic considering their contexts. adults captive capybara groups significantly different, confirming our hypothesis groups’ differences. richness interactions mediated vocalization capybaras suggests that species’ communication an important mechanism to regulate encounters alert members group about environmental cues.
