Entre as modalidades de produ??o de sinais vibroac?sticos est?o a estridula??o e a percuss?o. Estes sinais podem transmitir mensagens de alarme, distresse, recrutamento, ataque, ativa??o da col?nia, pistas para o provisionamento de larvas, avalia??o de recursos alimentares e n?o receptividade das f?meas. Tendo isso em vista, este estudo teve como objetivo investigar a utiliza??o de sinais ac?sticos na esp?cie Neoponera villosa (Hymenoptera, Formicidae, Ponerinae), caracterizando a estridula??o de oper?rias, gynes e machos, analisando a resposta de col?nias de N. villosa diante da estridula??o de coespec?ficos e avaliando a resposta ac?stica das col?nias ? perturba??o do ninho. Os resultados mostraram que os sinais estridulat?rios de oper?rias de N. villosa s?o compostos majoritariamente por sequ?ncias monossib?licas de chilros, sendo um chilro composto por uma ?nica sequ?ncia de pulsos. Entretanto, a maior parte dos chilros das castas reprodutivas apresentaram uma sequ?ncia de pulsos de baixa amplitude antecedendo a sequ?ncia de pulsos principal, sendo, dessa forma, constitu?dos por duas sub-unidades e caracterizando-se como chilros dissil?bicos. Os sinais estridulat?rios apresentaram ainda diferen?as significativas entre as castas quanto ao intervalo entre chilros, n?mero de pulsos por chilro, intervalo entre pulsos e taxa de emiss?o de pulsos. Diferen?as entre col?nias foram encontradas na estridula??o de gynes e machos. As col?nias de N. villosa n?o responderam aos sinais estridulat?rios de oper?rias, com mudan?a do padr?o comportamental em resposta apenas ? presen?a de companheiras de ninho e de n?o companheiras, mas sem diferen?a de resposta entre os testes com presen?a e aus?ncia de estridula??o. No contexto de perturba??o do ninho, as col?nias de N. villosa n?o responderam com emiss?o de sinais estridulat?rios, mas sim com emiss?o de sinais ac?sticos produzidos atrav?s de percuss?o. / Acoustic and vibratory signals are used by several ant species in intraspecific and interspecific interactions, although studies concerning these signal modalities are scarce. Stridulation and drumming are among the main ways of producing vibroacoustic signals. These signals can transmit messages relative to alarm, distress, recruitment, attack, colony activation, clues for provisioning of larvae, evaluation of food resources and non-receptivity of females. The aim of this study was to investigate the use of acoustic signals in Neoponera villosa (Hymenoptera, Formicidae, Ponerinae). In order to achieve our aim, we characterized workers, gynes and males stridulation; we analyzed N. villosa colonies? response to workers? stridulation and evaluated the acoustic response of N. villosa colonies to nest disturbance. The results showed that stridulatory signals of N. villosa workers are composed mainly of monosyllabic chirp trains, with chirps composed of a single sequence of pulses. Nevertheless, the majority of the chirps produced by the reproductive castes presented a low amplitude pulse sequence preceding the main high amplitude sequence of pulses. These chirps were composed of two subunits and, thus, were identified as disyllabic chirps. The stridulatory signals presented significant differences among the N. villosa castes regarding the inter-chirp interval, the number of pulses per chirp, the inter-pulse interval and the pulse repetition rate. In addition, gynes? and males? stridulation presented significant differences according to their colonies. N. villosa colonies did not respond to the emission of workers? stridulatory signals. Behavioral pattern changes occured only in response to nestmate or non nestmate presence, without any response difference between tests with stridulanting workers and mute workers. In nest disturbance context, N. villosa colonies did not respond with stridulatory signal emission, but with the emission of acoustic signals produced by drumming.

Mais especificamente, o artigo apresenta um estudo focado na adapta??o de algumas de suas composi??es as quais n?o foram escritas originalmente para serem executadas por um ?nico int?rprete (formato solo). A metodologia consiste na ?nalise deste repert?rio e suas respectivas t?cnicas composicionais. Posteriormente, extra?ram-se novas vers?es, com car?ter experimental, focados na intera??o entre instrumentos de percuss?o e recursos tecnol?gicos. Tais possibilidades foram implementadas atrav?s das oficinas de experimenta??o. Como resultado, gerou-se uma nova possibilidade de interpreta??o para a obra Clapping Music (1972). Deste modo, o trabalho aqui reportado visa apresentar as considera??es relacionadas ? performance, os processos utilizados para a implementa??o, assim como os resultados obtidos durante as oficinas. Concluiu-se que tais implementa??es, aliadas ? intera??o com recursos tecnol?gicos, proporcionaram ao int?rprete um maior aprofundamento do aspecto t?cnico/interpretativo, assim como das possibilidades de intera??o entre instrumentos de percuss?o e dispositivos eletr?nicos. / This study aims to identify, according to the literature and discography, new performance possibilities for minimalist works of American composer Steve Reich, written between 1972 and 1983. More specifically, the article presents a study focused on the adaptation of some of its compositions which were not originally written to be executed by a single performer (solo format). The methodology consists of analyzing this repertoire and their compositional techniques. Posteriorly, new versions were extracted with experimental character, focused on the interaction between percussion instruments and technological resources. Such possibilities were implemented through experimentation workshops. As a result, it generated a new possibility of interpretation for the work Clapping Music (1972). Thus, the work reported here is to present the considerations related to performance, the processes used to implement, and the results obtained during the workshops. It was concluded that such implementations, combined with interaction with technological resources, provided the interpreter further deepening of technical/interpretative aspect, as well as the possibilities of interaction between percussion instruments and electronic devices.
