Resumo: | Communication is fundamental for the survival of animals and can be genetically defined (innate) or socially learned. During the process of vocal learning small modifications occur in the vocalizations, producing geographical variations. Eupsittula cactorum, as well as other Psittaciformes, present social learning and have rely strongly on acoustic communication for social interactions. The species is a common target for trafficking, and recovered individuals have been constantly released into the wild. The present work aims to obtain information on the acoustic communication of the species and apply it on releasing protocols. We obtained recordings from four populations in Brazilian north-east and individuals under recovery at CETAS-Fortaleza. The voices of the natural populations were used to describe the vocal repertoire, where geographical variation was detected through a multinomial regression. Captive individuals were recorded before and after quarantine and monthly after release. In the presence of geographical variation, we tested the vocal similarity of the released individuals to the release areas using a multinomial regression, applied the acoustic parameters in a PCA and calculated the Euclidian distance of each vocalization to the origin and a polynomial regression to check for vocal convergence. Nine vocalizations were described, associated to specific behaviors, with no semantic redundancy. The populations presented dialects and the classification pointed that several individuals released by CETAS were released in areas that are linguistically distant. The experimental group converged vocally during quarantine, also converging to the local dialect of the region where they were released. Eupsittula cactorum demonstrated to have complex communication with vast vocal codification, yet flexible and capable of abridge the vocal differences between individuals allowing efficient communication, facilitating the reintroduction process. We suggest the use of vocalizations to determine the appropriate areas for releasing and that individuals can be previously trained with the regional dialect in order to minimize cultural differences between sylvatic and released individuals, improving individual socialization. |

Durante a aprendizagem vocal pequenas modificações surgem nas vocalizações, provocando variações geográficas. Eupsittula cactorum, assim como outros Psittaciformes, apresentam aprendizagem social e tem forte dependência da comunicação acústica para interações sociais. A espécie tem sido alvo recorrente do tráfico e indivíduos recuperados têm sido soltos na constantemente. Este trabalho objetiva obter informações sobre a comunicação acústica da espécie e aplicar isto à protocolos de soltura. Obtivemos gravações de quatro populações no nordeste do Brasil e indivíduos destinados à soltura no CETASFortaleza. Utilizamos as vozes das populações naturais para descrevermos o repertorio vocal e verificarmos a existência de variação geográfica através de uma regressão multinomial. Os indivíduos apreendido foram gravados antes de depois da quarentena e mensalmente após a soltura. Na presença de variações geográficas testamos a similaridade vocal destes com as áreas destinadas à soltura através de uma regressão multinomial e utilizamos parâmetros acústicos em uma PCA e calculamos a distância euclidiana de cada vocalização à origem e uma regressão polinomial afim de verificar se ouve convergência vocal. Descrevemos 9 vocalizações, associadas a comportamentos específicos, sem redundâncias na semântica. As populações demostraram dialetos e a classificação demonstrou que muito dos indivíduos provindos do CETAS foram soltos em locais linguisticamente distante. O grupo experimental convergiu vocalmente ao longo da quarentena, também convergindo para o dialeto local onde foram soltos. Eupsittula cactorum demonstrou possuir uma comunicação complexa, com uma vasta codificação vocal, porem flexível, capaz de diminuir as diferenças vocais entre indivíduos, afim de comunicarem-se de forma eficiente o que facilita muito processos de soltura Sugerimos utilizar as vocalizações para determinar os lugares mais apropriados à soltura e que os indivíduos sejam previamente treinados com o dialeto da região de soltura afim de minimizarem a diferença cultural entre soltos e selvagens, melhorando a socialização dos indivíduos.Universidade Federal da ParaíbaBrasilZoologiaPrograma de Pós-Graduação em Ciências BiológicasUFPBAraújo, Carlos Barros dehttp://lattes.cnpq.br/5916372318047686Martins, Bruno Araujo2019-01-02T21:22:15Z2019-01-022019-01-02T21:22:15Z2017-07-13info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttps://repositorio.ufpb.br/jspui/handle/123456789/12775porAttribution-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nd/3.0/br/info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da UFPBinstname:Universidade Federal da Paraíba (UFPB)instacron:UFPB2019-01-02T21:22:15Zoai:repositorio.ufpb.br:123456789/12775Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufpb.br/PUBhttp://tede.biblioteca.ufpb.br:8080/oai/requestdiretoria@ufpb.br|| diretoria@ufpb.bropendoar:2019-01-02T21:22:15Biblioteca Digital de Teses e Dissertações da UFPB - Universidade Federal da Paraíba (UFPB)false |
