... fitted a linear mixed-effects model to assess the effect of sex and ISI on the mean PTT, assuming an AR1 correlation structure to account for serial correlation between successive measures of PTT on the same larynx. An interaction term between sex and ISI was included in the model to determine whether...

... to explore the anatomy of the larynx and soft palate in the harbour seal ( Phoca vitulina ), and generate models for how valving mechanisms in the head and neck may function during breathing, phonating, diving and swallowing. Harbour seals have an elevated larynx and the epiglottis may rise above the level...

...Tobias Riede; Zhiheng Li; Isao T. Tokuda; Colleen G. Farmer ABSTRACT Sauropsid vocalization is mediated by the syrinx in birds and the larynx in extant reptiles; but whereas avian vocal production has received much attention, the vocal mechanism of basal reptilians is poorly understood...

... . The de-masculinization of these laryngeal features suggests an alteration in sensitivity to the gonadal hormones that are known to control the sexual differentiation of the larynx in other Xenopus and Silurana species. * Present address: David Geffen School of Medicine, University of California...

... to the larynx. Toothed cetaceans (Odontoceti) are capable of producing sounds at depth, either for locating prey or for communication. It has been suggested that during dives, air from the lungs and upper respiratory tract can be moved to the vestibular and nasal cavities to permit sound generation to continue...

... frequency and the volume of the whole larynx and ear. This is also the case for call pulse rate, indicating that for this species both spectral and temporal call parameters are biomechanically related to laryngeal size which is, in turn, largely mediated by body size. General body size effects might also...
