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 ...

Estudo da evolução vocal de Furnariinae (Aves: Furnariidae)
(Universidade Federal de Minas GeraisUFMG, 2018-03-03)
Birds vocalisation plays important roles in birds life and its evolution is shaped by several factors. The acoustic environment exerts considerable influences in the species vocal features, being that they tend to fit in ...
Vocal divergence between two disjunct populations of Giant Antshrike (Batara cinerea) is related to environmental conditions
(Wiley-Blackwell, 2019-05-01)
Variation in the avian vocal signals emitted may have a significant impact on species evolution. Vocal divergence in suboscine species like Giant Antshrike (Batara cinerea) may be associated with selective adaptation, since ...
Rats Synchronize Locomotion with Ultrasonic Vocalizations at the Subsecond Time Scale
(2016-09)
Acoustic signals have the potential for transmitting information fast across distances. Rats emit ultrasonic vocalizations of two distinct classes: “22-kHz” or “alarm” calls and “50-kHz” calls. The latter comprises brief ...
Canto de anúncio de Hyla jimi e Hyla elianeae (Anura, Hylidae) na região de Botucatu, São Paulo, Brasil
(2004-12-01)
In this work we present a description of the advertisement call of H. jimi, the locality type, and of H. elianeae, until now unknown in the literature. Field activities were carried out from August 1997 through June 1999; ...

Diverse patterns of temporal selectivity in the evoked vocal responses of a frog from the temperate austral forest, Batrachyla taeniata (Batrachylidae)
(Taylor and Francis, 2020)
Evoked vocal responses of male frogs Batrachyla taeniata to synthetic advertisement calls and variants having different temporal features altered parametrically were studied to identify patterns of evoked vocal responses ...
Histologic Study of Acute Vocal Fold Wound Healing After Corticosteroid Injection in a Rabbit Model
(ANNALS PUBL CO, 2010)
Objectives: Injectable corticosteroids have been used in phonosurgery to prevent scarring of the vocal fold because of their effects of wound healing, and to ensure better voice quality. We histologically evaluated the ...
