...D. Reby; M. T. Wyman; R. Frey; B. D. Charlton; J. P. Dalmont; J. Gilbert ABSTRACT Males of several species of deer have a descended and mobile larynx, resulting in an unusually long vocal tract, which can be further extended by lowering the larynx during call production. Formant frequencies...

...Elizabeth C. Leininger; Ken Kitayama; Darcy B. Kelley ABSTRACT Phylogenetic studies can reveal patterns of evolutionary change, including the gain or loss of elaborate courtship traits in males. Male African clawed frogs generally produce complex and rapid courtship vocalizations, whereas female...

...Eileen L. McIver; Margaret A. Marchaterre; Aaron N. Rice; Andrew H. Bass Toadfishes are among the best-known groups of sound-producing (vocal) fishes and include species commonly known as toadfish and midshipman. Although midshipman have been the subject of extensive investigation of the neural...

...Ni Y. Feng; Andrew H. Bass Melatonin is a well-documented time-keeping hormone that can entrain an individual's physiology and behavior to the day–night cycle, though surprisingly little is known about its influence on the neural basis of social behavior, including vocalization. Male midshipman...

...Christian Brandt; Jens Malmkvist; Rasmus L. Nielsen; Nanna Brande-Lavridsen; Annemarie Surlykke SUMMARY American mink ( Neovison vison ) kits are born altricial and fully dependent on maternal care, for which the kits' vocalizations appear essential. We used auditory brainstem responses (ABRs...

... for blind sand-dwelling chrysochlorid golden moles. Studying the vocal behaviour of captive piebald shrews, Diplomesodon pulchellum , we documented vibrations, apparently generated by the whole-body wall muscles, from 11 (5 male, 6 female) of 19 animals, placed singly on a drum membrane. The airborne waves...

...Sabyasachi Roy; Cory T. Miller; Dane Gottsch; Xiaoqin Wang SUMMARY The natural environment is inherently noisy with acoustic interferences. It is, therefore, beneficial for a species to modify its vocal production to effectively communicate in the presence of interfering noises. Non-human primates...

...Tine K. Rubow; Andrew H. Bass SUMMARY Seasonal and circadian rhythms control fundamental physiological processes including neural excitability and synaptic plasticity that can lead to the periodic modulation of motor behaviors like social vocalizations. Parental male midshipman fish produce three...

...Aaron N. Rice; Andrew H. Bass SUMMARY Toadfishes (Teleostei: Batrachoididae) are one of the best-studied groups for understanding vocal communication in fishes. However, sounds have only been recorded from a low proportion of taxa within the family. Here, we used quantitative bioacoustic...
