Perspectives and Progress in Animal Acoustic Communication

Effect of anomalous pulse timing on call discrimination by females of the gray treefrog (Hyla versicolor): behavioral correlates of neurobiology

“…Over the past 30-40 years, the communication biology of anuran amphibians has proved to be an especially edifying area for such an integrative approach (Capranica and Moffat, 1983;Gerhardt and Huber, 2002;Simmons, 2003). Cells exhibiting a variety of response characteristics exist at higher levels in the anuran auditory system and the structure of calls has been linked to these characteristics (Feng and Schellart, 1999;Gerhardt and Huber, 2002;Rose and Gooler, 2007).…”

Vocalization by extant nonavian reptiles: A synthetic overview of phonation and the vocal apparatus

“…segregation) have internal reference for the species concerned and provide accurate information to conspecific receivers about the quality or properties of the signaler (Fitch & Hauser, 2003;Simmons, 2003;Wiley, 2006). Distress signals (Figure 1a,c) have external reference with regard to the calling species and provide accurate information about the signaler beyond its own species-specific world.…”

“…When acoustic communication is achieved via vocalization (Ladich & Winkler, 2017), oral expulsions of air are emitted either as turbulent noise or as vibratory sound generated by constriction(s) somewhere along the upper respiratory tract, typically, but not exclusively, involving structures within the larynx (Fitch & Hauser, 2003;Ladich & Winkler, 2017). Such signals may be arbitrary, with no link between the acoustic structure of the emitted sound and its meaning (as in distress calls, but see above) (Fitch & Hauser, 2003;Simmons, 2003), or may be direct, with a specific link between its meaning and its entailed acoustic structure (as in advertisement calls; Fitch & Hauser, 2003). In the latter, the expulsion of air must be able to be modulated and reproduced consistently in form and pattern (Marcellini, 1978).…”

A Qualidade De Transmissão Da Vocalização Em Câmaras No Solo Da Espécie Leptodactylus Troglodytes (Anura: Leptodactylidae)

“…A comunicação se baseia no envio de uma informação de um emissor para um receptor e o veículo pelo qual essa informação é passada é chamado sinal (Simmons, 2003). A comunicação acústica é muito importante na reprodução dos anfíbios anuros, pois o macho emite o canto, a fêmea interpreta este sinal e usa suas características acústicas paraselecionar o parceiro sexual (Simmons, 2003). Neste contexto, estudos prévios têm mostrado que fêmeas, de várias espécies, exibem preferências por propriedades acústicas as quais há um alto gasto energético por parte do macho que vocaliza (Gerhardt& Huber, 2002).…”
