Variation among vocalizations of Taraba major (Aves: Thamnophilidae) subspecies
(Taylor & Francis Ltd, 2018-01-01)
Geographical variation of bird vocalizations may be related to factors influencing sound production and sound propagation. If birds, e.g. the Great Antshrike (Taraba major), produce vocalizations that develop normally in ...
Social group signatures in hummingbird displays provide evidence of co-occurrence of vocal and visual learning
(Royal Society Publishing, 2019)
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 ...
Environmental conditions drive vocal variation in the scaled dove (Columbina squammata)
(2022-01-01)
Variations in communication systems profoundly affect bird evolution. Vocalizations mediate species recognition and therefore intra-specific variation may lead to reproductive isolation, ultimately resulting in speciation. ...
Modificações vocais e laríngeas ocasionadas pelo som basal
(Universidade Federal de Santa MariaBRFonoaudiologiaUFSMPrograma de Pós-Graduação em Distúrbios da Comunicação Humana, 2006-08-21)
The present study aimed at examining both vocal and laryngeal changes caused by the vocal fry in five female subjects without vocal complaints, signs nor symptoms, with no report of previous voice therapy, and free of ...
Análises perceptivo-auditiva e acústica de vozes de cantores líricos pré e pós aquecimento vocal
(Universidade Federal de Minas GeraisUFMG, 2013-01-14)
Objectives: Compare auditory-perceptive and vocal acoustic parameters of lyric singers pre and post vocal warm-up, developed during the research, in order to demonstrate additional data for the comprehension of the effects ...
Variations in the arrangement of South American sea lion (Otaria flavescens) male vocalizations during the breeding season: Patterns and contexts
(European Association for Aquatic Mammals (EAAM), Alliance of Marine Mammal Parks and Aquariums (AMMPA), International Marine Animal Trainers’ Association (IMATA), 2003-12)
We analysed whether South American sea lions (Otaria flavescens) varied the syntax or arrangement of vocalizations (the order in which calls were produced) according to different social contexts. Three male calls that ...
Snipe taxonomy based on vocal and non-vocal sound displays: the South American Snipe is two species
(Wiley Blackwell Publishing, Inc, 2019-10-26)
We analysed breeding sounds of the two subspecies of South American Snipe Gallinago paraguaiae paraguaiae and Gallinago paraguaiae magellanica to determine whether they might be different species: loud vocalizations given ...
