(Universidade Estadual Paulista (Unesp), 2018-03-15)
Os anuros apresentam diferentes tipos de canto, com diferentes funções no contexto social, classificadas por observações de campo e experimentos de playback. No presente estudo descrevemos as vocalizações emitidas por ...
Rufous horneros perceive and alter temporal coordination of duets during territorial interactions
(2021-04-01)
Temporal coordination of duets consists of nonrandom overlap, alternation or association between rhythms of acoustic elements. Since duet coordination presumably requires high attentiveness between signallers, the coalition ...
Biotic and abiotic sounds affect calling activity but not plasma testosterone levels in male frogs (Batrachyla taeniata) in the field and in captivity
(Elsevier, 2020)
In animals, the expression of diverse reproductive behaviors is hormonally regulated. In particular, vocalizing during courtship has been related to circulating androgen levels, and reciprocally, conspecific vocalizations ...
Dual Function of Chip Calls Depending on Changing Call Rate Related to Risk Level in Territorial Pairs of White-Eared Ground-Sparrows
(2017-03)
Different mechanisms have been proposed for encoding information into vocalizations: variation of frequency or temporal characteristics, variation in the rate of vocalization production, and use of different vocalization ...

Song-based species discrimination in a rapid Neotropical radiation of grassland seedeaters
(Wiley, 2015-01)
Acoustic signals among newly diverged taxa have the potential to convey species identity, information that is key to reducing hybridization. Capuchino seedeaters constitute a remarkable example of recently radiated endemic ...

(WILEY-BLACKWELLHOBOKEN, 2015)
Complex Call with Different Messages in Bokermannohyla ibitiguara (Anura, Hylidae), a Gladiator Frog of the Brazilian Cerrado
(Soc Study Amphibians Reptiles, 2014-09-01)
The Gladiator Frog, Bokermannohyla ibitiguara, is a hylid endemic to the Brazilian Cerrado with a complex call composed of long and short notes. We describe the influence of male size and temperature on call properties and ...
Vocalizações de Dendropsophus nanus (Anura: Hylidae) e a modulação de comportamento ante estímulos acústicos
(Universidade Estadual Paulista (Unesp), 2010)
The aim of this study is to analyze the vocalizations of Dendropsophus nanus and its responses to the dominant frequencies of conspecific calls. There were made playback experiments by broadcasting calls of different ...
