The Ecology and Behavior of Amphibians
species of anurans (fig. 7.6). Most accounts of vocal sac anatomy have focused
on taxonomic implications rather than the functional significance of structural
variation (C. Liu 1935b; Liem 1970; M. Tyler 1971, 1972, 1974, 1985a; M. Hayes
and ...
Acoustic energy that is transduced by the laryngeal apparatus acts on the buccal
cavity and vocal sac. The vibration of these structures intensifies the acoustic
signal, resonating and radiating it across the surface of the vocal sac into the air.
William E. Duellman, 1994

Hormones and Reproduction of Vertebrates
The squamous epithelium lining the vocal sac is thin, nonkeratinized, and non-

Cycloramphinae), which ...

Whereas a cavity resonator has rigid walls that are assumed to reflect most
