Vocalization by extant nonavian reptiles: A synthetic overview of phonation and the vocal apparatus
@article{Russell2020VocalizationBE, title={Vocalization by extant nonavian reptiles: A synthetic overview of phonation and the vocal apparatus}, author={Anthony Patrick Russell and Aaron M. Bauer}, journal={The Anatomical Record}, year={2020}, volume={304}, pages={1478 - 1528} }
Among amniote vertebrates, nonavian reptiles (chelonians, crocodilians, and lepidosaurs) are regarded as using vocal signals rarely (compared to birds and mammals). In all three reptilian clades, however, certain taxa emit distress calls and advertisement calls using modifications of regions of the upper respiratory tract. There is no central tendency in either acoustic mechanisms or the structure of the vocal apparatus, and many taxa that vocalize emit only relatively simple sounds. Available…

Comparative anatomy of the middle ear in some lizard species with comments on the evolutionary changes within Squamata
- BiologyPeerJ
- 2021
The results provide an overall idea of the amount of variation of the middle ear while helping to infer the evolutionary history of the lizard middle ear and indicate high levels of homoplasy in the variation ofThe columella-extracolumella ratio, providing a better understanding of the ratio variation among lizards.
Geographic variation in the matching between call characteristics and tympanic sensitivity in the Weeping lizard
- BiologyEcology and Evolution
- 2021
This work explored the match between spectral characteristics of the distress calls and the tympanic sensitivities of two populations separated by more than 700 km, and found that populations differed in signal and receptor characteristics and that this signal variation was explained by population differences in body size.

Functional morphology of the Alligator mississippiensis larynx with implications for vocal production
- BiologyThe Journal of Experimental Biology

Morphology and laryngeal biomechanics are used to model the boundaries of the alligator's available acoustic space, providing a systematic description of the possible acoustic space that could be available to an alligator larynx.
A Chinese alligator in heliox: formant frequencies in a crocodilian
- PhysicsThe Journal of Experimental Biology

Frequency peaks in bellows of a Chinese alligator breathing a helium–oxygen mixture instead of air shift to significantly higher frequencies, showing that crocodilian vocalizations contain vocal resonance frequencies or ‘formants’.
Subglottal pressure and fundamental frequency control in contact calls of juvenile Alligator mississippiensis
- BiologyJournal of Experimental Biology
- 2011
The morphological and physiological features of sound production in alligators are investigated and it is concluded that the alligator larynx represents a sound source with only two control parameters (subglottal pressure and vocal fold adduction) in contrast to the mammalian larynX in which three parameters can be altered to modulate frequency.
